Sam Bankman-Fried was ready to shell out some major cash to stop Donald Trump from running for president in 2024, according to author Michael Lewis.

The fallen crypto billionaire, who is set to stand trial over the collapse of his cryptocurrency exchange FTX, was willing to put up $5 billion to keep Trump out of the 2024 presidential race, having deemed him an existential threat to democracy, Lewis told 60 Minutes in an interview broadcast Sunday.

The journalist unpacked Bankman-Frieds logic while promoting his new book, Going Infinite: The Rise and Fall of a New Tycoon, which reportedly contains an anecdote about the proposal.

He took the view that all the big existential problems are gonna require the United States government to be involved to solve em, Lewis said on the news show. And if the democracy is undermined, all these problems are less likely to be solved. And he saw Trump trying to undermine the democracy, and he thought, Trump belongs on the list of existential risks.
