AI agents have helped produce a proposed solution to a decades-old mathematical problem, and GPT-6 Astra has completed all 48 levels of a CAPTCHA-style browser game. Other OpenAI agents generated more than 15,000 edits on a German wiki they repurposed without its operator’s permission. The incidents involved different systems, but together they explain why enthusiasm about AI’s capabilities is growing alongside concern about its control. OpenAI’s chief scientist is urging caution, researchers are quitting over safety fears, and Bridgewater is proposing a 35% tax on AI token consumption to help share the economic gains. My latest article examines what these achievements actually demonstrate, where supervision is falling short, and what stronger safeguards could mean for jobs and AI investment.

Major US stock market indexes ended the week mixed, with narrow leadership again masking broader weakness. The Dow and equal-weight S&P 500 declined, while the S&P 500 and Nasdaq Composite gained, supported by Nvidia and a handful of other large stocks.

September’s poor historical record added to the cautious mood. Since 1928, the S&P 500 has fallen in 55% of Septembers, averaging a 1.1% loss, according to Citadel Securities. The pattern is far from dependable, though: Ameriprise’s Anthony Saglimbene notes that the sharpest declines have generally coincided with deteriorating market or economic conditions.

Several strategists nevertheless saw reasons to become more defensive. JPMorgan’s Andrew Tyler turned tactically cautious ahead of the September 16 Fed decision, while Wells Fargo’s Ohsung Kwon questioned whether financing constraints could slow the AI investment boom. Citadel Securities’ Scott Rubner pointed to fading support from earnings season, retail buying and corporate buybacks. He remained constructive longer term but favored trimming exposure into rallies.

Positioning complicates the bearish case. Goldman Sachs’ prime brokerage data showed US long/short hedge-fund net leverage falling to 47.6%, near the bottom of its one-year range, as shorts and hedges grew faster than longs. That leaves room for positive surprises to trigger buying as managers unwind defensive bets. Yet aggregate equity positioning remained overweight, while systematic funds had already rebuilt exposure after July’s selloff. The market therefore enters September with fewer obvious sources of incremental buying, but enough bearish positioning to amplify an upside surprise.

Nvidia rose 5.9% after agreeing to buy Hugging Face for about $13 billion in a push beyond chip sales. The platform would give Nvidia a larger role in the software ecosystem supporting demand for its hardware. DA Davidson’s Gil Luria viewed the deal as a defensive move that keeps a key platform for open AI models out of rivals’ hands.

Globally, country ETFs were mostly higher, with the global ex-U.S. equity index increasing 1.1%.

Global growth also strengthened in August: the J.P. Morgan Global Composite PMI rose to a 27-month high of 53.5, with new orders expanding at the fastest pace since May 2023. Services regained the lead at 53.7, its highest in 20 months, while manufacturing remained solid at 52.3. Activity expanded across all 21 sectors tracked by S&P Global, and inflation pressures eased to their weakest since February.

Crypto assets advanced alongside gains in several non-US equity markets, with Bitcoin and total market capitalization both rising 2.3%. Bitcoin again failed to break above $80,000, but institutional demand remained supportive, with weekly inflows reaching $987 million.

According to CME FedWatch, the implied Fed funds path changed little overall but became slightly more back-loaded. The probability of a September hike increased to 59.4% from 57.0%, while the expected timing of a second 25 bp increase moved back to January from December. Futures now imply around 25 bp of cumulative tightening by year-end 2026, slightly down from 27 bp a week earlier. John Williams and Christopher Waller initially pushed hike expectations below 50% by emphasizing recent inflation progress, before Friday’s stronger payroll report reversed much of that move. Next week’s CPI is likely to be decisive for the September meeting.

The Treasury curve, by contrast, steepened more visibly. According to Bloomberg, the 1-year yield declined 2 bp to 4.11%, while the 10-year rose 6 bp to 4.78% and the 30-year increased 3 bp to 5.24%. Long-dated Treasuries were caught in a broader global sovereign-bond selloff as higher energy prices revived inflation concerns and investors demanded more compensation for heavy government borrowing and an approaching wave of corporate issuance.

America may spend $15.07 trillion on data centers through 2050, but money and chips are no longer the only constraints. At least 75 US projects worth about $130 billion were blocked or delayed by local opposition in Q1 2026, and 71% of Americans say they would oppose an AI data center near their community. Concerns over electricity bills, water use, noise and limited permanent employment are turning zoning hearings into a material risk for the AI investment cycle. The build-out is unlikely to stop, but slower approvals and cancelled sites could delay orders for GPUs and power equipment, raise project costs and redirect investment toward communities willing to accept it.

The AI investment cycle may have found a constraint that cannot be solved by issuing bonds or ordering more chips: local consent.

U.S. equities finished the week modestly higher, but the gains were again concentrated in the largest companies. The S&P 500 rose 0.5% and the Nasdaq Composite 0.9%, yet the equal-weighted S&P 500 fell 0.5%. The style breakdown showed the same split: large-cap growth advanced 0.9%, while every mid- and small-cap segment declined. The Magnificent 7 gained 2.5%, adding more than $560 billion in market value compared with roughly $335 billion for the S&P 500 as a whole. That marked a clear reversal from the broader participation seen earlier in August.

Nvidia was the week’s main test of the AI trade. Its fiscal Q2 results were exceptionally strong: revenue rose 106% y/y to $96.2 billion, Data Center sales reached $89 billion, and management projected roughly 70% revenue growth for fiscal 2028. The shares initially jumped 8.7% after the report but finished the week only 1.3% higher after Friday’s hawkish rate repricing erased most of the post-earnings gain. Demand remains broad, with Nvidia saying supply continues to lag customer requirements. The harder question is financing the next stage of the buildout. Nvidia is increasingly helping customers and partners secure capital and backstop infrastructure projects, supporting near-term demand but also making the economics of the AI cycle more complex and reviving concerns about “circular” financing.

The macro backdrop added a second source of tension. In his first Jackson Hole speech as Fed chair, Kevin Warsh said the recent improvement in inflation was not enough to alter the Fed’s priority on price stability. Markets responded by lifting the probability of a September hike to 57.0% from 39.9% and bringing forward expectations for a second 25 bp increase to December from next summer. Stocks nevertheless absorbed the hawkish repricing relatively well, helped by resilient growth and earnings.

Six months into the U.S.-Iran war, the conflict appears to be exerting less influence on day-to-day equity trading than it did in the spring. Brent remains well above pre-war levels but has fallen substantially from its March peak as producers and shippers adapted. RBC still estimates that roughly 8 million barrels per day of Middle East supply is disrupted, yet traders largely looked through another week of stalled diplomacy. Iran has increasingly become a background inflation and energy-cost risk rather than the dominant daily catalyst for U.S. equities.

Globally, country ETFs were mostly lower, with the global ex-U.S. equity index declining 0.4%.

Crypto assets generally retreated, with Bitcoin falling 0.6% and total market capitalization declining 0.9%. The pullback was modest, and Bitcoin continued to receive support from institutional demand, with weekly inflows totaling $925 million despite the failure to break above $80,000.

According to CME data, the implied Fed funds rate curve over the next 18 months shifted higher by an average of 12 bp, leaving the implied policy rate for January 2028 around 14 bp above the prior week. The move was concentrated at shorter maturities, consistent with markets pricing a greater likelihood of near-term tightening after Warsh’s speech. Futures now imply around 39 bp of tightening by year-end, bringing a second increase into play as early as December rather than next summer.

The Treasury market reflected that shift through a pronounced flattening of the yield curve rather than a uniform rise in yields. The 1-year yield rose 12 bp to 4.13% and the 2-year climbed 10 bp to 4.34%, while the 10-year slipped 1 bp to 4.72% and the 30-year fell 6 bp to 5.21%. Part of the divergence may reflect investors taking Warsh’s inflation commitment seriously: tighter near-term policy could reduce the risk that inflation remains elevated for longer, limiting the premium demanded on long-dated bonds. Large fiscal deficits, heavy debt issuance and persistent inflation risk nevertheless remain unresolved.

Executive Summary

23/08/2026

U.S. equities pulled back, with the S&P 500 falling 1.4%, the Nasdaq Composite 2.1% and the Dow 0.9%. The weakness was broad across size and style, although value held up better than growth. Health care, energy and materials still advanced, but the market had a distinctly defensive tone. The sharpest pressure fell on semiconductors and the broader AI complex, where the move looked more like profit-taking in a crowded trade than a clear deterioration in demand.

Even within semiconductors, flows were mixed. SMH recorded $1.7 billion of outflows, while SOXX attracted about $670 million. BofA’s August Fund Manager Survey showed the same tension: long global semiconductors remained the market’s most crowded trade, but the share identifying it fell to 53% from 82% in July, while 71% of managers still did not expect a major hyperscaler to cut capital spending this year. That points to de-risking within AI rather than an outright exit from the infrastructure cycle.

Morningstar expects Nvidia to deliver another beat-and-raise quarter, while Stifel and Oppenheimer also expect results and guidance to exceed consensus. The question has shifted from whether AI demand exists to whether future revenue and cash flow can justify the scale of spending already committed. The roughly $3 trillion of future obligations discussed in our recent article is therefore better viewed as a source of greater market sensitivity than as the direct trigger for this week’s decline. With expectations already high, Nvidia’s Wednesday results may hinge less on the headline beat than on China guidance, gross margins and the product roadmap.

Macro headlines added pressure but never produced a consistent market reaction. Higher oil prices and long-term yields weighed on equities early in the week, while the Treasury’s bond-buyback announcement produced only a brief rebound. Overall, the week looked more like an orderly reset in stretched positioning than a response to one decisive catalyst.

Globally, country ETFs were mixed, with the global ex-U.S. equity index broadly flat. Chip-heavy Japan, Taiwan and South Korea declined, offset by gains elsewhere.

Business activity across the G4 strengthened further in August, with the average Flash Composite PMI rising to 53.5 from 52.9, a 39-month high. The US led at 56.0, driven mainly by services. The eurozone and UK improved to 52.1 and 52.5, while Japan climbed to 53.4. The recovery broadened toward services and final demand, although inflation remained uneven and business confidence subdued.

Crypto assets staged a sharp rebound, with Bitcoin gaining 24.3% and total market capitalization rising 22.3%. The move was helped by a sudden improvement in the policy backdrop: the SEC proposed its Regulation Crypto Assets framework, President Trump renewed pressure for passage of the Clarity Act, and the Treasury’s buyback announcement briefly pushed yields and the dollar lower. In a market heavily positioned for further weakness, that was enough to trigger a sharp reversal.

According to CME data, the implied Fed funds curve shifted higher by about 4 bp over the next 18 months as stronger economic data reinforced the case for restrictive policy. The probability of a September hike rose to 39.9% from 33.1%, while futures now imply around 26 bp of cumulative tightening by year-end 2026, up from 24 bp.

Treasuries moved only modestly on the week despite a sharp midweek swing. The 1-year yield rose 5 bp to 4.01%, the 10-year 4 bp to 4.73%, and the 30-year 1 bp to 5.27%. The Treasury’s decision to at least double long-bond buybacks briefly pushed yields lower. Investors remain focused on inflation, uncertainty over the Fed path and large fiscal deficits. With public debt above $40 trillion, the buyback program looks more like temporary relief than a solution to pressure on the long end.

Executive Summary

20/08/2026

The August 2026 Bank of America Global Fund Manager Survey shows investors leaning even further into risk, with sentiment near its most bullish levels of the past four years and equity exposure at the highest since late 2021. Cash fell to 3.5%, keeping BofA’s contrarian sell signal active, while global equity allocations climbed to a net 56% overweight. The macro backdrop remains constructive but less clear-cut: growth expectations eased slightly, yet a record 56% of managers now expect “no landing” and profit expectations are the strongest since 2021. U.S., Eurozone and emerging-market equities all saw higher allocations, while commodities also gained and bonds remained deeply underweight. The result is a market positioned for resilient growth, strong earnings and persistently firm nominal activity, with little cash left as a buffer if the outlook disappoints.

The main tension is that optimism is increasingly colliding with valuation, inflation and financing risks. Investors still expect AI capex to remain strong, and semiconductors remain the most crowded trade, though crowding concerns have eased from July’s extreme. At the same time, the AI bubble, a disorderly rise in bond yields and renewed inflation now rank almost equally as the biggest tail risks, while hyperscaler spending is seen as the most likely source of a future systemic credit event. Managers are also becoming more selective, favoring high-quality earnings, value and dividends rather than pure momentum. Overall, the survey remains bullish, but positioning is increasingly one-sided: investors are betting on strong profits and continued AI investment even as leverage rises, cash shrinks and the margin for error narrows.

The August Bank of America Global Fund Manager Survey shows investors becoming even more aggressively positioned for continued economic growth and rising corporate earnings.

Big Tech’s AI bill is far larger than reported capex suggests. According to the Wall Street Journal, nine technology companies have accumulated about $3 trillion of future lease and purchase commitments that have not yet appeared on their balance sheets. As these commitments turn into payments, hyperscalers are borrowing at an unprecedented pace, increasing bond supply and paying wider premiums even though most remain highly rated. J.P. Morgan estimates that roughly $2 trillion of the data-center buildout could ultimately be financed through investment-grade credit markets.

The consequences extend beyond technology companies. Heavy issuance is beginning to affect corporate-bond spreads and compete with government debt for investor capital, while the infrastructure itself is straining electricity systems. Sixty planned US data centers could generate annual emissions equivalent to 27 coal plants, as utilities add gas capacity and delay some coal retirements to provide reliable power. The AI boom is moving from Big Tech’s income statements into bond portfolios, power grids and carbon emissions.

The AI infrastructure boom is much larger than headline capital-expenditure figures suggest.

16/08/2026

U.S. equities were little changed at the headline level, but the underlying market was stronger than the major indexes suggested. The S&P 500 gained 0.4% and the Nasdaq 0.1%, while the Magnificent 7 lost 1.2% and the Dow fell 0.6%. Beneath the surface, however, breadth improved: large-cap value rose 1.0%, mid- and small-cap stocks gained around 1%, and the share of S&P 500 companies trading above their 200-day moving average reached its highest level since early December. Weakness was concentrated in several megacaps and selected consumer and healthcare names, while gains spread across financials, industrials, software and other parts of the market.

Strong earnings remain the main foundation. Bloomberg Intelligence estimates that S&P 500 profits are tracking about 31% above year-earlier levels, versus 23% expected before earnings season, with more than 90% of companies having reported. Margins are approaching 16%, helped by stronger productivity and early evidence that AI investment is beginning to lift profits rather than simply raise costs. 22V Research estimates AI-related productivity has added roughly 150 bp to margins. Importantly, strength extends beyond the megacaps, with positive earnings growth across almost every sector and unusually strong beat rates among mid- and small-cap companies. JPMorgan and Ed Yardeni responded by lifting their S&P 500 targets to 8,000 and 8,400, respectively.

The macro backdrop also became less threatening. Softer inflation and retail-sales data reduced expectations for a near-term Fed hike, while the lack of progress on reopening the Strait of Hormuz had little lasting impact on risk appetite. Volatility fell further, with the VIX near its lowest level since early 2026. At the same time, options markets showed unusually strong demand for upside exposure. Citadel Securities reported heavy call buying across at least 170 S&P 500 stocks, activity Steve Sosnick of Interactive Brokers described as “FOMO insurance” — investors reluctant to chase the market outright but equally reluctant to miss further gains.

Global equities also advanced, with the global ex-U.S. index up 0.6%. Asian technology markets led, with South Korea gaining 8.2% and Taiwan 3.9% as enthusiasm around AI hardware and memory demand revived. Japan rose 1.4% and broader emerging markets gained 1.5%. China moved the other way, falling 3.4%, while Brazil dropped another 4.0% as election and fiscal uncertainty triggered heavy foreign selling. Bloomberg reported more than 13.5 billion reais ($2.6 billion) of foreign equity outflows from Brazil through Wednesday.

Crypto underperformed other risk assets. Bitcoin fell 2.9% and total market capitalization declined 2.0%, pressured by fading optimism around the CLARITY Act, another regulatory delay from the SEC, and $385 million of weekly outflows from U.S. spot Bitcoin ETFs. The market is increasingly pricing slower progress on U.S. crypto legislation rather than an imminent regulatory breakthrough.

Rates markets became modestly less hawkish. CME data show the implied Fed funds curve shifted about 4 bp lower over the next 18 months as softer inflation and demand data reduced the urgency for another hike. The probability of a September increase fell to 33.1% from 44.4%, and markets pushed the likely timing of the next move from October to December. Futures now imply about 24 bp of cumulative tightening by year-end 2026, down from 30 bp a week earlier.

Treasuries, however, sent a more mixed signal. The 1-year yield fell 3 bp to 3.96%, reflecting reduced expectations for near-term tightening, while the 10-year rose 4 bp to 4.69% and the 30-year climbed 6 bp to 5.26%. The divergence suggests investors are less worried about an immediate Fed hike but still demand greater compensation for holding long-dated debt. Persistent fiscal deficits and heavy bond supply remain key concerns, helping keep the yield curve steep even as the expected policy path moves lower.

Executive Summary

08/08/2026

U.S. equities rallied broadly, with the S&P 500 gaining 3.6%, the Nasdaq Composite 5.2% and the Dow 3.0%. Unlike several recent weeks, the advance extended well beyond mega-cap technology, with large-, mid- and small-cap stocks all higher, although growth remained the clear leader.

The main catalyst was a more favorable macro backdrop. Early in the week, progress toward reopening the Strait of Hormuz eased fears of prolonged disruption to global energy supplies, pushing oil lower and reducing inflation concerns. Friday then added a second boost: the U.S. economy lost 23,000 jobs in July, while payroll gains for May and June were revised down by a combined 103,000. The weak report reduced expectations for near-term Fed tightening and pulled Treasury yields lower.

Strong earnings gave the rally a firmer foundation. Citadel Securities argued that the recent reduction in speculative retail positioning had removed some technical excess, while positive earnings surprises and an expected pickup in corporate buybacks provided additional support. That helps explain why equities responded so strongly when the macro backdrop improved. The counterpoint is sentiment: Bank of America’s Bull & Bear Indicator climbed to 9.7, its highest since 2021, suggesting that increasingly bullish positioning may itself be becoming a source of vulnerability.

Global equities moved higher alongside Wall Street, with the global ex-U.S. index up 2.9%. Brazil was the notable exception, with EWZ falling 3.6% as political and fiscal uncertainty intensified ahead of October’s presidential election. A widely expected 25 bp Selic cut to 14% offered little relief, while escalating tensions with Washington added to the country-specific risk premium.

Global economic activity also improved in July. The J.P. Morgan Global Composite PMI rose to 52.6 from 52.0, a five-month high consistent with roughly 2.6% annualized GDP growth. Services drove most of the improvement, while manufacturing remained in expansion but lost some momentum as precautionary inventory building faded. New business grew at the fastest pace since February and employment increased for the first time since April. Investment-related sectors — particularly AI, technology equipment, machinery and defense — remained an important source of strength. Inflation pressures eased as energy costs declined, although price growth remained elevated in the U.S. and Japan.

Crypto advanced with other risk assets. Bitcoin rose 3.2% and total market capitalization gained 2.1%. U.S. spot Bitcoin ETFs attracted $865 million, the strongest weekly inflow since April. The market is also becoming increasingly institutional: professional investors accounted for 72% of spot trading volume on Wintermute’s OTC desk in the first half of 2026, up from 59% a year earlier. That shift toward ETFs, derivatives and institutional trading may help explain why Bitcoin’s current drawdown has been more gradual than in previous crypto downturns.

Rates markets became noticeably less hawkish after the weak jobs report. CME data show the implied Fed funds curve shifted about 9 bp lower over the next 18 months. The probability of a September hike fell to 44.4% from 67.0%, pushing the likely timing of the next tightening move to October, while expectations for a second hike moved from January to next summer. Futures now imply around 30 bp of cumulative tightening by year-end 2026, down from 37 bp a week earlier.

Treasury yields moved lower in response. The 1-year fell 5 bp to 3.82%, the 10-year declined 8 bp to 4.65%, and the 30-year eased 7 bp to 5.20%, according to Bloomberg. The combination of softer employment, lower oil prices and easing inflation concerns gave investors more confidence that the Fed can afford to move cautiously rather than tighten aggressively.

What Happened in Semiconductors?

The correction began on June 23. By then, the PHLX Semiconductor Sector Index, or SOX, had more than doubled during the first half of 2026 and reached a record high.

The rally was not based on hype alone. According to Goldman Sachs data, it was supported by a powerful increase in consensus forward earnings. Heavy investment by hyperscalers created shortages of advanced memory and other AI-related components, pushing chip prices, margins and earnings sharply higher.

Fundamentals improved, prices followed, and semiconductors became one of the clearest winners of the AI investment cycle.

But strong trends attract capital. Very strong trends attract too much of it.

The Bank of America Fund Manager Survey shows how quickly the trade became crowded. The share of respondents identifying “long global semiconductors” as the world’s most crowded trade rose from 24% in April to 73% in May, 80% in June and 82% in July.

By late June, prices had started to move ahead of earnings estimates, while positioning had become increasingly extreme. The sector was therefore vulnerable before any obvious trigger appeared.

There was no single event behind the reversal. Instead, several concerns arrived: higher Treasury yields, the financing and free-cash-flow consequences of AI investment, reports of excess computing capacity, stronger competition, more efficient open-source AI models and doubts about whether elevated memory-chip margins could be sustained.

Profit-taking was therefore not the sole cause of the decline. It was the mechanism through which a crowded trade began to unwind. Once prices stopped rising, leveraged and momentum-driven positions became vulnerable to forced selling.

The resulting moves were extreme. SOX fell 21% in July, its worst month since October 2008, despite rebounding 8.3% during the final two sessions. By month-end, every constituent was below its June peak, and almost two-thirds had lost at least 25%.

Volatility was just as unusual. On nearly half of July’s trading days, SOX closed at least 4% higher or lower. Every one of the month’s 22 sessions had an intraday range of at least 2%, something that had not happened since 2020.

ETF flows add an important twist to the story. The largest unlevered semiconductor ETFs received approximately $6.3 billion in June and $11.8 billion in July. SOXX and SMH alone attracted a record $11.4 billion in July.

This suggests that investors were not simply abandoning semiconductors. Our interpretation is that exposure was changing hands: leveraged, momentum and single-stock investors were reducing risk, while longer-term and dip-buying investors were adding exposure through ETFs.

Still, record inflows do not prove that the crowded trade has been fully cleared. The fact that prices continued falling despite unprecedented ETF demand shows how powerful the selling pressure had become.

July was painful for the strategy, but the drawdown was concentrated in a very specific market event: the sudden unwind of one of the strongest and most crowded momentum trades of the year. Momentum strategies benefit when trends persist, but they can also face sharp pressure when those trends reverse after becoming over-owned.
