What does Costco entering the Medicare market mean for you? Well, at this time, not much.
The initial rollout is tiny: Medicare Advantage products in two states and a Medigap product in a third. The markets haven’t even been announced yet. SCAN is based in CA, so they are a major consideration as a trial state.
This is admittedly an “experiment” for Costco, but one that could have serious market implications:
Costco’s membership and cult following are driven by: high membership retention and low margins. Ultimately, if volume is high enough (it ALWAYS is), then Costco takes a hit on their margins to provide immense value to their members—with the goal of customer trust and loyalty.
Now picture that when it comes to Medicare: a corporate giant, that is NOT a healthcare dominant institution, forcing the current players to be more competitive 👀
Medicare over the last four years has been a vacuum of provider and carrier in-fighting, billing misalignment, fraud, and new-agent saturation. If all of these dynamics are tested by a company that has virtually no stake (they don’t run on healthcare…) and external market security with the brand-buffer they’ve got??? With the MONEY they’ve got?
This could be a total flop and Costco will bow out quietly and continue offering the tastiest frozen foods in the country.
OR
Costco gives the Medicare industry the most unexpected kick in the ass imaginable. Maybe its presence puts pressure on premiums and benefits, or its pharmacy footprint changes how drug benefits are delivered. MAYBE a company obsessed with protecting its brand forces a higher standard of transparency in an industry whose marketing practices have earned enormous consumer distrust.
And maybe competitors suddenly have to ask a question they haven’t always been forced to ask: Would our members actually choose us if they trusted the company standing next to us more?
Could that ultimately contribute to a healthier, more stable Medicare market?
I have absolutely no idea. But Costco entering Medicare was not on my 2026 bingo card, and I’m very interested to see what happens.
