Going Infinite — The Rise and Fall of a New Tycoon

Going Infinite Review

Michael Lewis published Going Infinite while Sam Bankman-Fried was on trial for fraud, and the timing could not have been more awkward. Lewis had spent a year with SBF and FTX before the collapse; his book, by his own account, was meant to be the story of an eccentric genius reshaping global finance through effective altruism and cryptocurrency. What he ended up with was a portrait of a man who may have committed one of the largest financial frauds in history — and Lewis had to decide how to write it anyway.

His decision was to be honest about his own uncertainty. This is either the book’s greatest strength or its most frustrating quality, depending on what you want from it. Lewis does not conclude that SBF is a calculating fraudster or an oblivious idealist who lost control of something too large for him to manage. He presents the evidence for both interpretations and acknowledges he cannot determine which is true. The prosecutors and the jury concluded otherwise, but Lewis is writing journalism, not a verdict.

What Going Infinite captures brilliantly is the atmosphere of FTX at its height: the absurdity of the Bahamas compound, the effective altruism culture that convinced everyone involved they were saving the world, the incompetence that apparently coexisted with genuine trading brilliance, the way SBF’s particular brain — possibly autistic, certainly unusual — processed risk and relationships in ways that made him simultaneously compelling and unknowable.

Lewis is a beautiful writer and Going Infinite is a beautifully written book. It is less satisfying as a forensic account of how the fraud happened, because Lewis is candid that he does not entirely know, and the prosecutors’ version was still being constructed when he wrote it.

For readers who want narrative intimacy with one of the strangest financial stories of the decade, this is the essential text. For readers who want accountability and explanation, it will frustrate.

Our rating: 4.0/5 — An unusual Lewis book — more impressionistic than analytic — but the intimate access to SBF makes it irreplaceable as a document of the FTX era.

The Access Problem

Lewis’s access to Sam Bankman-Fried before the FTX collapse was extraordinary and, in retrospect, complicated. He met SBF in early 2021, when FTX was a rising force in cryptocurrency and Bankman-Fried was being discussed as a potential future billionaire-philanthropist of historic scale. Lewis spent roughly a year embedded with SBF and his team, attending meetings, traveling with them to events, and interviewing Bankman-Fried extensively. He was present in the Bahamas compound in the final weeks before the collapse.

This level of access is what makes Going Infinite irreplaceable as a document of FTX at its height. No other journalist was inside the operation for this long, with this level of cooperation. It is also, inevitably, what makes the book complicated. Lewis had built a journalistic relationship with his subject, and that relationship constrained what he could write and how he could frame it even when the subject was eventually convicted on multiple counts of fraud.

Sam Bankman-Fried’s Conviction

SBF was convicted in November 2023, one month after Going Infinite was published, on seven counts of fraud and conspiracy. He was subsequently sentenced to 25 years in federal prison. Lewis, writing before the verdict, had framed the book around his genuine uncertainty about whether SBF was a calculating fraudster or an idealist who had lost control of a system too complex for him to manage. The jury’s verdict did not resolve Lewis’s intellectual uncertainty, but it resolved the legal question.

Lewis has been candid in subsequent interviews that the timing was difficult and that the conviction required him to explain publicly why his book took the position it did. His explanation — that he is a journalist reporting what he observed, not a prosecutor determining guilt — is consistent with his approach across his career, but it tested the limits of the approach in a way that the previous books had not.

Effective Altruism at FTX

One of Going Infinite’s most valuable contributions is its account of the effective altruism culture that pervaded FTX. SBF was a committed effective altruist who had taken the philosophy seriously enough to organize his entire financial life around it: earning as much as possible in order to give as much as possible to causes with the highest expected utility per dollar. This ideology was not peripheral to the FTX operation; it was load-bearing in the organizational culture and in the decision-making patterns that prosecutors would later characterize as fraud.

Lewis’s portrait suggests that SBF’s effective altruism was genuine — that he genuinely believed what he said about giving — and that this genuineness was compatible with the financial practices that led to the collapse. The ideology may have made it easier, not harder, to rationalize decisions that harmed FTX’s customers: if the end goal was planetary benefit, intermediate financial arrangements were a second-order concern.

Whether this explanation exculpates, mitigates, or simply contextualizes the fraud is a question Going Infinite raises without resolving — which is either its greatest virtue or its central failure, depending on what you expect financial journalism to do.

Going Infinite was published in October 2023, one month before Sam Bankman-Fried’s conviction on seven counts of fraud and conspiracy in November 2023. He was subsequently sentenced to 25 years in federal prison in March 2024 — a legal conclusion that arrived after Lewis had completed the manuscript and which Lewis has addressed in subsequent interviews without revising the book’s deliberately open-ended framing.
