Yellowstone National Park is getting the largest financial gift in its history: a $105 million fund aimed at everything from scientific research to a brand-new visitor center near one of its most famous thermal areas. The money comes from Tallgrass, a Blackstone Infrastructure portfolio company, working alongside the National Park Service and the nonprofit Yellowstone Forever.
A Record-Setting Donation With Three Priorities
According to nbcmontana.com, the National Park Service, Yellowstone Forever and Tallgrass announced the creation of the fund this week, with the money split across three stated priorities: advancing conservation and scientific research, improving park infrastructure and visitor experiences, and expanding opportunities for Wyoming students and communities to experience Yellowstone. The Business Journals described the fund as a sweeping effort by Tallgrass Energy to support conservation, the visitor experience and opportunity for Wyoming residents.
The fund will also establish what's being called the Tallgrass WYld Yellowstone Initiative, per WyoFile. That outlet also notes the National Park Service estimates Yellowstone carries $1.2 billion in deferred maintenance and repairs — a backdrop that helps explain why a gift of this size is drawing so much attention.
One-Third Could Build a New Norris Geyser Basin Visitor Center
A chunk of the money has a very specific destination. A new $35 million visitor center at Norris Geyser Basin is among the projects being considered with the new fund, according to ksl.com. Wyoming Public Media reports that around a third of the donation is intended to fund that new visitor center in the Norris Geyser Basin area, while the rest is earmarked to improve park access for Wyoming students, infrastructure, research and conservation.
Importantly, the park itself is expected to retain control over how the money actually gets spent. Per the same account from Wyoming Public Media, Yellowstone is expected to get the final say in how to use the funds, and Tallgrass has said it will have no involvement in how the park uses the money.
Who Is Tallgrass, Exactly?
Tallgrass's own identity comes with a wrinkle. The Business Journals described the company behind the gift as Tallgrass Energy, while WyoFile characterized Tallgrass as a multi-commodity infrastructure company based in Colorado.
What is clear is that Tallgrass recently exited the oil business. The company sold its oil business last month for $2.5 billion to a Canadian company, Wyoming Public Media reported, a sale that preceded this week's announcement of the Yellowstone fund.
How Big Is This Gift, Really?
Multiple outlets have cast the $105 million fund as a watershed moment for the park's finances. Wyoming Public Media reported that the donation, from Blackstone portfolio company Tallgrass, is the largest financial gift in National Park Service history, while WyoFile separately described it as the largest single private gift in the agency's history.
Former Yellowstone superintendent Dan Wenk put the scale of the gift in blunt terms, telling 891khol.org, “It certainly exceeds, by many times, the largest previous donations to Yellowstone National Park.”
Why the Timing Matters for Wyoming and the Park
The gift lands at a moment when Yellowstone's popularity and its price tag are both climbing. The National Park Service reported that Yellowstone welcomed 4,762,988 recreation visits in 2025, and separately found that tourism to the park contributed $828 million to the local economy and supported 8,560 local jobs. Against that backdrop, and the park's $1.2 billion deferred maintenance estimate cited by WyoFile, a fund aimed at infrastructure, research and access for Wyoming communities touches nearly every pressure point the park is currently facing.
