The Yellowstone $105 million gift comes from Tallgrass, a Blackstone portfolio company, and goes to Yellowstone National Park, as reported on October 19, 2026. The gift is for conservation, research, infrastructure improvements and visitor access. Officials call it the largest single private gift in National Park Service history. This story could not verify that ranking. The $105 million is 3.05 times the $34,471,459 revenue that Yellowstone Forever reported for its fiscal year ending February 2026, according to ProPublica.
Who announced the $105 million Conservation and Stewardship Fund and what it funds
The National Park Service, Yellowstone Forever, a nonprofit, and Tallgrass announced the creation of the $105 million Conservation and Stewardship Fund to provide long-term support for the park, according to NBC Montana. WyoFile reports that Yellowstone National Park and Tallgrass have launched a $105 million conservation and stewardship fund and called it the largest single private gift in the agency's history. Yellowstone spans more than 2.2 million acres across Wyoming, Montana and Idaho, and was established in 1872 as the world's first national park.
A portfolio company is a business that an investment firm owns or has invested in. WyoFile reported that Tallgrass, which is building an AI power hub near Cheyenne, has operated in Wyoming for more than a decade.
Among the projects the fund will pay for is a $35 million visitor center at Norris Geyser Basin. Steven Davidson, senior vice president at Tallgrass, said of the sprawling basin: "There's no place for you to sit and engage with a ranger directly." He said the center will offer opportunities for experiences that are a bit more interactive.
Interior Secretary Doug Burgum said in a press release: "This historic $105 million investment honors that legacy, bringing together the best of American enterprise and conservation to expand access to Yellowstone and inspire the next generation to experience America's great outdoors." He thanked Blackstone, Tallgrass and Yellowstone Forever for their partnership and extraordinary commitment.
Yellowstone Forever Form 990 records put the $105 million fund in scale
Yellowstone Forever is one of the three groups that announced the fund. Its latest Form 990 is the annual information return that U.S. nonprofits file with the federal government. For the fiscal year ending February 2026, the filing reports revenue of $34,471,459 and contributions of $25,096,994, according to ProPublica's Nonprofit Explorer. That year ended before the fund was announced.
The $105 million fund is 3.05 times that revenue and 4.18 times those contributions. The sources do not say over how many years the $105 million will be paid. The nonprofit's contributions were $34,396,651 in the fiscal year ending February 2025 and $15,526,996 in the year ending February 2024, so its contributions have swung widely from year to year.
Can the largest private gift claim in National Park Service history be checked?
The ranking rests on what officials say. The Form 990 filings cover one nonprofit, so the Yellowstone Forever records cannot test a claim about every gift the agency has received. No list of earlier Park Service gifts was pulled for this story.
The claim is narrow. It covers a single gift, not total private giving to national parks. The records here show scale, not rank. Checking the claim would take a dated list of Park Service gifts with amounts.
