Toward the end of Michael Lewis’s seductive new book, “Going Infinite: The Rise and Fall of a New Tycoon,” about the epic collapse of the cryptocurrency exchange FTX and its enigmatic founder, Sam Bankman-Fried (SBF, as he’s known), Lewis describes flying in 2022 from California to D.C. As the plane descended, Bankman-Fried, who was then one of the wealthiest people on the planet and a massive donor to political campaigns, told Lewis that he had explored whether it would be legally possible to pay Donald Trump to not run for president in 2024. Through an unknown channel, Bankman-Fried’s team unearthed, Lewis writes, “the not terribly earth-shattering news that Donald Trump might indeed have his price: $5 billion.” Lewis, who at this point had spent a great deal of time with Bankman-Fried and his colleagues, does not appear to have found this extraordinary claim worth looking into further.
