Suppose tpus were theoretically a million times better, but cannot be produced due to supply chain constraints, this action would still be rational.
My personal take is that this really shows how bottlenecked the entire supply chain is. For such an important commodity there are shockingly few players ready for scale.
1. Indeed, Google is compute-constrained, and is ready to buy any it can.
2. xAI (now SpaceXAI) has a lot of idle compute, which it resells to Cursor, Anthropic, Google, probably others as we speak.
In other words: Google is training models, xAI is not.
"Both SpaceX and Google have the option to terminate the agreement with 90 days’ notice after December 31, 2026"
In other words, this is a fake IPO booster
