Anthropic is burning gas to feed the AI boom

Judgment

Anthropic executives and its IPO investors face a sharper tradeoff: lock in on-site natural gas turbines to keep data-center buildout on schedule, or accept delays and higher power-procurement costs while fuel and turbine shortages persist.

Basis

Anthropic's S-1, filed Monday with the SEC, says data centers are increasingly reliant on natural gas and that "competition for access to electrical supply and data center locations with adequate power availability is intense." The mechanism: Anthropic leases hyperscaler capacity but announced a $50 billion plan to expand data centers in Texas and New York; some planned sites rely on on-site gas turbines. A turbine shortage is slowing construction, so developers install on-site gas engines and simpler turbine technology to avoid grid interconnection waits, making power less efficient and more polluting. Anthropic also says competition for gas and pipeline capacity from hyperscalers "could drive up the price of natural gas," and climate change will raise electricity and water costs for cooling. Gas is 40 percent of US power generation.
