At this point, openai and anthropic have no problems announcing these deals because is good narrative, and helps them raise funding and IPO.
The same thing happened in dotcom. Deals and partnerships were announced because it helped raise money. I recall energy companies (enron/dynegy) doing deals with network vendors. Eventually, the deals were not worth the ink on paper but it helped raise funding.
I don't see how they have an out now, not when there are so many hundreds of billions in circular loans to keep going.
