Anthropic’s compute commitments reached $517 billion covering 14.8 gigawatts in the 11 months through August 2026—nearly triple the prior estimate of roughly $180 billion through 2029. The disclosure comes as Anthropic approaches profitability for a second consecutive quarter ahead of a potential Nasdaq listing at up to $100 billion raised and a $2 trillion valuation.
Amazon and Alphabet account for about 11 gigawatts and more than $300 billion of the commitment. Microsoft covers more than $30 billion and roughly 1 gigawatt. SpaceX’s Colossus contributes about $45 billion, and AMD supplies a 2 gigawatt MI450 deal.
The scale is unprecedented. Half a trillion dollars of compute committed by a company that is only now approaching profitability is the largest bet in the industry—and it was disclosed the same weekend CEO Dario Amodei asked the industry to pace capability development. The two facts reconcile if you read his essay carefully: Amodei wants to pace capability, not deployment, and 14.8 gigawatts is deployment.
The Rum Group agreement is particularly notable. Anthropic is party to a $13.7 billion six-year agreement at Maysville, Georgia, structured in three tranches of roughly $4.57 billion with a penny warrant for up to 50.8 million shares worth about $364 million. The supplier has not secured financing, but Anthropic’s obligations are not contingent on it—terms that only a company confident of its IPO signs.
On the consumer side, Anthropic ended the temporary 50 percent weekly usage boost for Claude Code that had been active since May and replaced it with a permanent 25 percent increase over the original allowance—a net reduction of about 17 percent against the summer allowance. This lands on the same week ChatGPT Pro closed to new signups and DeepSeek priced peak hours at double the off-peak rate. Three labs in seven days are rationing demand rather than chasing it.
The $517 billion is commitments rather than spend, most of it lands after 2028, and the Rum Group site does not exist yet. The number that supports the commitment is the $65 billion run rate reported last week. The number that tests it is whether two quarters near profitability become four.
