They have a program now for sellers to qualify for merchant-fulfilled Prime. I'm assuming they have to be able to guarantee they can do 2-day shipping, and there is some sort of oversight to ensure they're meeting that. I'm not sure how widespread the program is. I did purchase something within the last year that was listed as Prime, got to me in 2 days, but did not ship from an Amazon fulfillment center.
