Lambda to Build Oklahoma Data Center With $500M Tax Pledge and Closed-Loop Cooling
Lambda Inc., which brands itself the Superintelligence Cloud, is building a new AI data center at MidAmerica Industrial Park in Mayes County, Oklahoma. The facility is projected to pay approximately $500 million in taxes over 10 years at current rates, generate up to 1,000 construction jobs, and support up to 100 permanent positions.
The power authority for the project is the Grand River Dam Authority, a public trust based in northeastern Oklahoma. GRDA CEO Dan Sullivan confirmed that Lambda will fund the upfront infrastructure costs required to serve the project, ensuring those expenses are not passed on to other GRDA customers. That cost-isolation structure is consistent with Oklahoma’s Data Center Customer Ratepayer Protection Act, which Lambda cited as a compliance anchor: the company is taking full responsibility for the resources and infrastructure needed to operate the facility, including paying 100 percent of its electricity costs.
Lambda has also signed the White House Ratepayer Protection Pledge and is designing the facility to function as a flexible grid customer, with the ability to shift or reduce certain computing loads during periods of peak demand — a load-shedding capability increasingly requested by grid operators managing the surge in AI data center power draw.
Water and Cooling
The facility will use closed-loop cooling technology, which Lambda says dramatically reduces water consumption compared to traditional data center cooling. Open-loop evaporative cooling — the conventional approach — draws large volumes of water and discharges thermal waste into local water systems. Closed-loop designs recirculate coolant in a sealed system, limiting freshwater intake and wastewater output.
The facility is planned for 375 megawatts of IT capacity on a 329-acre site. MidAmerica Industrial Park in Chouteau, Oklahoma, is managed by a public trust and is a designated industrial site with access to multiple interstates and logistics infrastructure.
Lambda’s Infrastructure Position
Lambda, founded in 2012 by published machine learning engineers, builds supercomputers for AI training and inference. Its customer base spans AI researchers, enterprises, and hyperscalers. The Oklahoma facility is the latest in a series of infrastructure moves: in May 2026, Lambda closed a $1 billion credit facility to expand its data center footprint, and in September 2026, NVIDIA took on a major lease position as part of a $35 billion arrangement involving Anthropic.
The Oklahoma announcement positions Lambda as a player in the large-scale AI infrastructure market. At 375 MW on 329 acres, the Mayes County campus is sized comparably to single hyperscaler data center campuses rather than co-location facilities. A $500 million 10-year tax figure is consistent with assessed plant value for a facility of that scale.
MidAmerica Industrial Park previously described it as a site ready for projects of this magnitude, having made prudent investments over the past decade to support large-scale development. GRDA’s statement that Lambda will fund upfront infrastructure costs positions the authority to avoid the ratepayer exposure that has complicated other large data center negotiations in the region.
