Summary
Ken Griffin, the billionaire founder and CEO of Citadel, has expanded his ownership of rare American founding documents by acquiring a second original first-edition printing of the U.S. Constitution, making him the sole private collector of both known surviving copies. This acquisition follows Griffin's landmark 2021 purchase of the first copy for $43.2 million at Sotheby's, which set a record as the highest auction price ever paid for a book, manuscript, or historic document.
The newly acquired Constitution makes its public debut on May 27, 2026, at the South Street Seaport Museum in Lower Manhattan, where it headlines the exhibition "The Promise of Liberty," a display timed to commemorate the 250th anniversary of American independence. This public unveiling adds to Griffin's broader philanthropic strategy surrounding these documents. His previously acquired Constitution copy remains on permanent loan to the National Constitution Center in Philadelphia, where it is accessible to the general public.
Griffin's commitment to public access extends beyond lending arrangements. In a major philanthropic gesture, he donated $15 million to the National Constitution Center—the single largest gift in the organization's history—and pledged to loan both his first-edition copies of the Constitution and Bill of Rights to the Pennsylvania institution for public exhibition. This donation reflects a deliberate strategy to ensure that these exceptionally rare historical artifacts, of which only a handful of first printings survive, serve educational and civic purposes rather than remaining purely private holdings.
The concentration of both known surviving private copies in Griffin's collection underscores the extreme scarcity of these founding documents. By securing both remaining copies and committing them to public display through museum loans, Griffin has positioned himself as a custodian of critical American historical artifacts while maintaining private ownership. This approach aligns with institutional investor and family office strategies of leveraging significant cultural acquisitions for both preservation and philanthropic impact.
