NASA has already awarded all the ISS crew flights up through it's scheduled retirement in 2030. Boeing is contracted for 6 flights, and SpaceX for 14 (including the 6 it has already flown). NASA hasn't published the milestone payment schedules, but the total contract was for $4.2 billion, so Boeing would have needed to budget a 26% profit margin on the whole endeavor to break even at this point. That wouldn't surprise me, but they are probably quickly reaching the point where they will actually be losing money.
