Anthropic locked in 3.5 gigawatts of compute power — then quietly disclosed in an SEC filing that the deal is contingent on its commercial success and still seeking partners to fund it. The bitcoin mining comparison landed as a headline. The fine print is more interesting.

Anthropic has contracted 3.5 GW of next-generation TPU capacity through Google and Broadcom for 2027-2031, directly competing with Bitcoin mining for electricity. The deal, disclosed via SEC filing, shows the agreement is contingent on Anthropic's continued commercial success and the parties are still seeking partners to fund deployment—details absent from Anthropic's public press release. Revenue has surged to $30B+ run-rate from $9B at end-2025, with over 1,000 customers now spending $1M+ annually.
Anthropic has signed agreements for 3.5 gigawatts of next-generation TPU compute, putting it in direct competition with the global bitcoin mining industry for cheap electricity. But the deal, disclosed in a Broadcom SEC filing and confirmed by Anthropic's blog, comes with a condition the press release omitted: Anthropic's access depends on its continued commercial success, and the parties are still looking for partners to help fund the deployment.
The numbers are large enough to be disorienting. Anthropic said its run-rate revenue has surpassed $30 billion, up from roughly $9 billion at the end of 2025, according to the company's blog post. More than 1,000 business customers now spend more than $1 million per year on Claude, doubling from 500 in less than two months, the same post shows. The company signed agreements through 2031 with Google and Broadcom for what Broadcom's 8-K describes as approximately 3.5 gigawatts of next-generation TPU capacity, expected online starting in 2027.
Bitcoin mining's electricity consumption is estimated at 13 to 25 gigawatts globally depending on hardware efficiency assumptions, according to the Cambridge University electricity consumption tracker (CBECI). Cambridge publishes this as a range reflecting methodological uncertainty across hardware efficiency assumptions, not a point estimate. Anthropic's contracted 3.5 gigawatt commitment falls within that range. The comparison is imperfect: Cambridge's figures are national-level aggregates that shift with hashrate and hardware efficiency, while Anthropic's is a contracted commitment that remains contingent on its business performance. Together they illustrate the scale of what AI infrastructure is competing for in the power market.
The SEC filing contains a detail Anthropic's blog post omitted. Broadcom says the parties are "discussing support for this deployment with operational and financial partners." A company that has locked in 3.5 gigawatts of power does not typically need to keep shopping for partners to fund the deployment. The press release called it infrastructure certainty. The filing calls it a work in progress.
This is happening as bitcoin miners are racing to sell their holdings and rebrand as AI infrastructure companies. Riot Platforms, MARA Holdings, and Genius Group disclosed selling more than 19,000 bitcoin from their treasuries in a single week, CoinDesk reported. Core Scientific, one of the largest publicly listed miners, is selling the majority of its bitcoin by the end of 2026 to fund conversion of its 1.2 gigawatt capacity toward AI data center operations through a deal with CoreWeave. More than $70 billion in AI and HPC contracts have been signed across the sector, and some miners could derive as much as 70 percent of their revenue from AI by the end of 2026, according to CoinDesk's market coverage.
The pattern is not subtle. Compute demand is rewriting power economics in real time. Miners who spent years building data center infrastructure next to cheap electricity are discovering that AI companies will pay more for the same capacity, and that selling bitcoin to fund the conversion is cheaper than raising equity in a market that currently values their mining assets at a fraction of their AI hosting potential.
Anthropic's $30 billion run-rate revenue figure suggests the company has the commercial basis to eventually consume the power it is contracting for. But "eventually" and "now" are different questions. The 3.5 gigawatt figure is a ceiling, not a baseline. The deal structure means the actual power draw in any given year will track Anthropic's revenue growth, not a fixed infrastructure timeline. That matters for grid planners, utility companies, and anyone building power infrastructure for AI workloads: the demand signal is real, but it is conditional, and it is still seeking partners.
What to watch next is whether the financial partners Broadcom and Anthropic are looking for actually appear, and whether Anthropic's revenue growth rate holds long enough to make the full 3.5 gigawatt commitment economically coherent. The scale got attention. The open question is whether it is real.
