Ken Griffin bought a rare first-edition copy of the U.S. Constitution at Sotheby’s in November 2021 for $43.2 million. (forbes.com)

Subsequent reporting through 2024–2025 consistently describes the document as his copy, noting that he has loaned it for public exhibition (first to Crystal Bridges Museum of American Art in 2022, and then to the National Constitution Center in Philadelphia, where it is to be displayed through the U.S. 250th anniversary exhibits into 2026).

There is no record of any resale—at auction or privately—of this specific Constitution copy since the 2021 Sotheby’s sale. Given the extremely high-profile nature of the document and the extensive coverage of Griffin’s subsequent loans and related historic-document purchases, a resale (especially at roughly double the original $43.2 million price) would almost certainly have generated prominent press, yet none exists.

Because Griffin still appears to own and loan the document and no evidence shows a resale within a year of the 2021 auction—let alone at about twice the price—the prediction that “in one year, he’ll sell it for twice as much” did not come true.
