In January, SoftBank contributed $50 million to the foundation for Donald Trump's future presidential library. The company said it would fund construction and operation. Presidential libraries preserve an administration's records and serve as monuments to its account of power. SoftBank's gifts to the Reagan and George W. Bush libraries came after those presidents left office. This payment arrived during Trump's term, before his library existed. In March, the Department of Energy leased federal land in Ohio to an affiliate of SoftBank's SB Energy. The former Portsmouth uranium-enrichment site is planned to hold a 10-gigawatt data center campus, supplied by at least 9.2 gigawatts of new gas generation.

Senators Elizabeth Warren and Richard Blumenthal and Representative Melanie Stansbury asked whether the timing raised bribery concerns. No published evidence connects the contribution to the lease. The two events expose a direct route between political remembrance and AI infrastructure. A corporation can honor a sitting president through an institution shaping his historical image while seeking federal land for one of the world's largest computing projects. The material chain includes a Cold War site under cleanup, gas plants, transmission lines, private servers and a commemorative foundation. SoftBank confirmed the dates and described the gift as resembling its previous library donations. Those checks reached former presidents. This one was deposited two months before the federal agreement was announced.
