Michael Belfiore reports that winners of COTS contracts will be ineligible for America’s Space Prize.

This makes sense. Bigelow probably wants to encourage as many players as possible, and he wants to encourage commercial space companies, so this spreads the wealth, increasing diversity in space access providers. And COTS winners don’t really need the prize money anyway. It’s the same philosophy that disqualified people from winning the X-Prize using government-developed hardware.
