Chicago hedge-fund billionaire Kenneth Griffin said he won a $43.2 million first-edition copy of the U.S. Constitution at a Sotheby’s auction on Thursday—and now he intends to lend it to a free Arkansas art museum.

The 53-year old founder and chief executive of Citadel caused a stir Thursday when he outbid a large group of cryptocurrency investors who had crowdfunded more than $40 million earlier in the week in a frenzied attempt to win the document, the last surviving first edition in private hands.
