OnePWR's $3.4 Billion AI Lab Sale Highlights Data Center Power Risks

OnePWR Solutions sold its power-generation platform to an unnamed AI lab for $3.4 billion in September, as Anthropic’s IPO filing warned of power supply risks for planned data centers.

Reached in late September, the reported arrangement covers commitments for 1.7 gigawatts of generation capacity. The figure describes equipment commitments, not electricity already being produced.

OnePWR sold its power-generation platform for $3.4 billion to an unnamed AI lab in September. The public transaction record does not identify Anthropic as the buyer or confirm the 1.7-gigawatt capacity.

Anthropic’s Nov. 2 IPO filing says some planned data centers rely on on-site natural-gas generation. The filing warns of volatile fuel costs, gas supply disruptions and pipeline constraints. The filing also lists approximately $895.4 billion in aggregate committed spending under purchase commitments and lease agreements as of and after Sept. 30, substantially all tied to computing and infrastructure. It does not connect that total to OnePWR.

Anthropic lists cryptocurrency mining operations among competitors for sites with adequate power. The competition adds context to its earlier warning that electricity constraints could raise data center costs.

On Feb. 11, Anthropic pledged to cover 100% of grid upgrades needed to connect data centers developed with partners for its workloads. For capacity leased from existing data centers, it was still exploring how to address effects on electricity prices. It also pledged to work toward adding power generation to match its data centers’ electricity needs.
