Most (and the biggest) BCBS licensees are for-profit. Kaiser is not but is still eye wateringly expensive. For me, a silver plan will be about $700-800 next year. And then you take a look at what a bronze plan covers…

This is correct. BCBS is for profit and most others are. Kaiser Foundation Health Plan is one of the few not for profit insurances and only available in 8 states.

BCBS AL, AR, CA, KS, HI, LA, MA, MI, MN, NC, ND, RI, TN and VT are all not for profit, as far as I can tell.

Not an exhaustive list, just asked AI and quickly checked it's output with google.

Kaiser is the biggest HMO in the country (and available in DC).
