On July 4, 2026, as the USA marks its 250th birthday, a library will open within the North Dakota Badlands that appears much less like a civic establishment than a manifesto inbuilt stone and metal. Designed by the worldwide structure agency Snøhetta, the Theodore Roosevelt Presidential Library in Medora would be the nation’s solely carbon-neutral presidential library—a monument to conservation, management, and the rugged individualism of the twenty sixth president, rising from the very panorama that made Roosevelt who he was.
Finishing it required one ultimate reward. On Thursday, that reward arrived: $26 million from Kenneth C. Griffin, founder and CEO of the $69 billion hedge fund Citadel. The library’s west wing will bear his identify.
It was not the most important examine Griffin has ever written. Not even shut. However it’s actually revealing.
The collector of American founding myths
To know what Griffin is doing in Medora, it helps to start out in Philadelphia—or, extra exactly, at a Sotheby’s public sale in November 2021, the place Griffin paid $43.2 million for a primary printing of the USA Structure, outbidding an web collective of 17,000 cryptocurrency fanatics who had crowdfunded beneath the identify ConstitutionDAO. The value set an all-time report for a e-book, manuscript, or historic doc offered at public sale.
Then, this previous spring, Griffin quietly did one thing stranger: He purchased the one different surviving first printing of the Structure nonetheless in non-public palms—the so-called Van Sinderen copy—for an undisclosed sum. He now owns each of them. Of the roughly 500 copies printed for delegates to the 1787 Constitutional Conference in Philadelphia, 13 are identified to outlive. Eleven are held by establishments just like the Library of Congress and the Nationwide Archives. The opposite two belong to at least one man.
Griffin has loaned each copies to museums for public show—one to the Nationwide Structure Heart in Philadelphia, and a donation of $15 million to the Structure Heart, the most important single reward in that group’s historical past. The opposite was loaned to the South Road Seaport Museum in New York, the place it anchors an exhibition referred to as The Promise of Liberty: Phrases That Formed a Nation.
A portfolio of patriotism
Griffin’s philanthropic report is huge. He has given an estimated $2 billion to charitable causes—and notably various: Harvard, the College of Chicago, Chicago’s Museum of Science and Business, the Artwork Institute of Chicago. However working by a major slice of his giving is a particular, recurring topic: America itself, as an thought.
He has funded the restoration of the Lincoln Memorial. He made the most important donation in Navy SEAL Basis historical past and the most important non-public reward ever to the Name of Responsibility Endowment, a veterans’ employment fund. He gave $30 million to the Nationwide Medal of Honor Museum Basis. By way of Griffin Catalyst, his civic engagement initiative, he introduced a sweeping dramatic presentation of American WWII historical past to audiences in New York and Miami.
And now: a presidential library for Theodore Roosevelt, within the Badlands, opening on the nation’s 250th anniversary.
Every reward is defensible, even admirable, in isolation. Taken collectively, they type one thing that appears much less like philanthropy and extra like curation—a deliberate, decades-long effort to color a selected imaginative and prescient of American historical past: constitutional, militarily honorable, frontier-spirited, and outlined by meritocratic striving fairly than inherited privilege.
“In our nation’s 250-year historical past, few People have embodied the spirit of management as totally as Theodore Roosevelt,” Griffin mentioned in Thursday’s announcement. “His imaginative and prescient, braveness, and dedication to public service left a permanent mark on our nation.”
TR was the unique trust-buster—a capitalist who believed in vigorous markets and equally vigorous civic accountability, who thought nice males had an obligation to public life, and who constructed his id within the very Badlands the place Griffin has now written his identify on a constructing.
The stress on the core
What complicates the portrait—and makes it a extra fascinating story—is that Griffin has been one of many Republican Celebration’s most dependable megadonors and fiercest critics of its present course. He spent greater than $100 million on conservative candidates within the 2024 election cycle, however declined to again now-President Donald Trump.
The break grew to become extra public and pointed in Could 2025, when Griffin appeared on the Milken Institute’s International Convention and described Trump’s tariff regime as having “regretfully—already unleashed an period of crony capitalism.” He referred to as it “terrifying to look at” and described companies lobbying the White Home for tariff exemptions as “nauseating“—the spectacle of a authorities selecting winners and losers because the antithesis of the American story he has spent a whole bunch of thousands and thousands setting up.
By Could 2026, he was again to writing GOP checks—$5 million to the Congressional Management Fund for Home Republicans—however his critique of the administration’s financial course has remained constant.
Maybe the selection of Teddy Roosevelt is deliberately symbolic—a lion of the Republican Celebration whose heterodox positions and social liberalism paint a special imaginative and prescient of what the occasion, and nation, might be. Clearly, Griffin doesn’t thoughts that concept of the Republican Celebration—and that concept of America.
