Anthropic draft IPO filing shows large planned compute payments to Alphabet

A reported draft filing from Anthropic, the AI lab in which Alphabet holds a stake, lists more than $600 billion of long-term computing contracts. Within that total, Anthropic plans to pay Alphabet about $111 billion, a larger figure than the commitments named for Amazon and Microsoft. For Alphabet holders this ties a meaningful slice of cloud and compute demand to one customer whose IPO is approaching, which adds to the concentration question already raised by Alphabet's recent Cloud and capex commentary.
