Actually I have the opposite take. This is largely a play to procure compute capacity (and I suspect, distribution via Google Cloud), and I think Dario wildly underestimated the amount of demand they would see.

I always wondered why Anthropic was not out there feverishly scrambling to procure compute like the other big players. While Altman was being laughed at as a "podcasting bro asking for trillions in investment" Dario was on Dwarkesh expounding on how tricky it is to predict the demand for capacity. Now Dario has to give equity to a competitor to get compute. (OpenAI does this too, of course, but I suspect the terms are much better.)

At this point, it's pretty clear that compute is the only moat in this business. Even as an outsider, the extreme demand curves and compute crunch were painfully obvious, so this seems like a serious strategic error on Dario's part.
