Anthropic warned in its Monday IPO filing that its growing reliance on private natural‑gas‑powered data centers could become a significant short‑term risk. The company noted that the rapid expansion of gas‑fueled facilities might push prices higher in certain regions, potentially hampering its AI projects and affecting other data‑center operators nationwide.
As the United States continues to see a surge in data‑center construction, the sector’s demand for natural gas is set to skyrocket. Many operators are choosing to build on‑site gas plants rather than wait for grid connections that could take years. Cleanview, an energy‑analysis firm, estimates that behind‑the‑meter gas projects under development will total 110 gigawatts by October 2026, up from just 20 gigawatts in July 2025.
Anthropic cautioned that competition from other gas‑fired data centers could expose it to fuel‑price volatility and supply disruptions beyond its control, raising the cost of natural gas and complicating its ability to secure firm fuel contracts.
The heightened demand arrives amid an already tight natural‑gas market. U.S. export terminals are sending increasing volumes abroad, driven by geopolitical tensions and federal export incentives. Export demand is projected to double over the next decade.
Even a modest portion of the planned data‑center pipeline could add a sizable load. BloombergNEF estimates that grid‑connected data centers alone could require an additional 15 billion cubic feet per day of natural gas by 2035, representing a 15 percent rise in overall demand. A conservative view of on‑site gas capacity would add another 3 billion cubic feet per day by the end of the decade.
Historically, Anthropic has rented compute capacity from major cloud providers such as Amazon, Google, Microsoft and SpaceX. The company currently leases space at SpaceX’s Colossus data center in Memphis, Tennessee, which is facing a lawsuit over unpermitted gas turbines.
In recent months, Anthropic has begun leasing and developing its own data‑center facilities to reduce dependence on other tech giants and gain greater operational control. The IPO highlights a $50 billion partnership with Fluidstack, announced last year, that will deliver data‑center development and operations services. The firm has disclosed plans for sites in Texas and New York.
These moves increase exposure to rising natural‑gas prices. Anthropic is also linked to large on‑site gas projects in Louisiana, Texas and West Virginia, the latter potentially becoming one of the nation’s biggest gas plants according to developer Nscale’s IPO filing.
The geographic spread of Anthropic’s facilities makes it vulnerable to regional gas‑supply shocks, especially in the Southeast where projects must compete with LNG export terminals. “It wouldn’t be surprising if you start to see gas become more expensive in Louisiana and Texas, where all the LNG projects are concentrated,” said Enrique Gonzalez, head of gas research for the Americas at BloombergNEF.
Texas, in particular, is a national hub for behind‑the‑meter data‑center development, intensifying competition for a possibly limited gas supply. Anthropic’s prospectus acknowledges this risk, noting that heightened competition for the same natural‑gas supply and pipeline capacity could drive up prices and hinder the company’s ability to lock in firm fuel contracts.
Any strain on gas supplies could also ripple into residential energy bills. Gonzalez believes producers learned from the 2022 energy crisis, when soaring gas prices spurred increased production that eventually lowered costs. While markets may not see such dramatic swings in the near future, he warned that higher hub prices could be passed on to consumers unless legislation intervenes.
Renewable energy offers a carbon‑free alternative, but Anthropic mentioned it only briefly in its filing, dismissing newer sources such as solar, wind, battery storage, nuclear and geothermal as potentially unavailable in the needed quantities or on the required timelines, or as being more costly.
