The real massive revenues that the big tech companies are having aren't going to disappear just because OpenAI goes away.

The real revenues of small and mid-sizes tech companies might, though. Which might be funny (in a Road Runner & Wile E. Coyote way) but only after considerable time and distance. Saying that, I think of those guys from The Big Short being reprimanded for celebrating their prediction of a market crash.

The financial impact if the whole AI space loses even 50% of its current "valuation" will be huge. The financial impact of the whole AI space continuing at its current velocity is... More of whatever is going on now?
