The Public Spat Between Binance’s CZ and OKX’s Star Xu Just Got Ugly — and Billion-Dollar Bets Are Involved

Changpeng Zhao released his autobiography on April 8, 2026. The book, Freedom of Money, was marketed using all the language of a thoughtful, post-incarceration reckoning, including reflections written in a federal prison cell using $0.05-per-message terminals, meditations on minimalism, and 72 life principles. CZ is currently richer than Bill Gates, with an estimated net worth of $110 billion. In October 2025, President Trump granted him a pardon.

In February 2026, he was present at the inaugural World Liberty Financial Forum in Mar-a-Lago. A reformed man returning to the arena with hard-won wisdom was how the book was framed. He was on X offering the founder of a competing exchange a $1 billion bet over his divorce status within a day of the article’s publication. This memoir is not the product of a man at peace, whatever else it may be.

Star Xu, the founder of OKX, Binance’s most direct and significant rival in the international cryptocurrency exchange market, is the person on the other side of that bet. The two have been connected for over ten years, dating back to the early days of OKCoin, the exchange that came before OKX, where CZ was employed prior to starting Binance. A single passage in the memoir tore apart that history, which was apparently never fully resolved.

CZ (Binance) vs Star Xu (OKX) — Key Facts & Dispute Timeline

According to CZ, during a dinner in 2025, Huobi founder Leon Li informed him that Star Xu had personally reported Li to Chinese authorities. CZ links this action to Li’s approximately 90-day soft detention by Chinese police in 2020. The accusation is specific, grave, and ascribed to a third party. In a post that went viral on cryptocurrency Twitter, Xu immediately and visibly denied the claim, calling it “completely false information” and characterizing CZ as having “a long-standing habit of making misleading statements to the public, the media, and the world.”

Then Xu continued. He resurfaced evidence that OKCoin had first published in 2015 the day after the memoir was released. According to Xu, notarized video and QQ chat logs show two versions of a contract sent from CZ’s account to early Bitcoin investor Roger Ver, with the later version having a six-month termination clause that was absent from the original.At the time, CZ defended himself by claiming that his QQ account might have been accessed by someone else. In 2026, Xu summed up that defense in four words: “Do you believe that?” When you read those posts in order, it’s like watching someone carefully arrange papers on a table; they’re not yelling, they’re just organizing things and taking a step back.

Feuds between individuals who have spent years together in the same rooms have a unique texture. Unlike the type of social media conflict that burns brightly and then fades, the CZ-Xu animosity has a precise, accumulated quality. From somewhat similar beginnings, these two men created rival empires. A 364-page memoir revealed their shared acquaintances, overlapping histories, and seemingly unresolved grievances. It’s like watching someone who has been waiting a very long time for a suitable moment to say certain things as Xu methodically works through the thread, supporting each claim with ten years’ worth of documentation.

It’s worth looking at the $1 billion wager itself to see what it reveals. In response to Xu’s inquiry about his divorce status, CZ declared on X that he was legally divorced and offered to wager any amount Xu desired. Xu had suggested that CZ might be lying about his marital status to conceal Binance equity ownership, citing the Bezos and Gates divorces as examples of appropriate asset separation.

He refused to provide documentation because he was worried about his ex-wife’s privacy. “As the UBO of a regulated company, publicly offering a $1 billion bet is hardly professional conduct,” Xu said, declining the wager. One of those things that is hard to write about is the contrast between CZ’s book and CZ’s actions in the day that followed its publication. Of the 72 principles in the memoir, Principle 16 promotes minimalism and stoic detachment. Stoic minimalists are not usually known for their nine-figure Twitter wagers on personal disputes.

The feud has, somewhat unintentionally, achieved what a cautious memoir would typically attempt to avoid: it has put two conflicting public records side by side in real time. The book, with its account of growth-era oversights, administrative compliance failures, and the contrast with Sam Bankman-Fried, is on one side. The DOJ’s November 2023 findings, on the other hand, reveal that Binance processed hundreds of millions in ransomware proceeds and darknet market activity while deliberately facilitating transactions for Hamas, Al Qaeda, ISIS, and Palestinian Islamic Jihad. At the time, Treasury Secretary Janet Yellen made a straightforward statement: Binance’s shortcomings “allowed money to flow to terrorists, cybercriminals, and child abusers.” Prosecutors uncovered internal Binance communications in which a compliance officer joked that the exchange could promote itself as the place to go when “washing drug money” was too challenging elsewhere. Forgetting paperwork does not naturally result in a four-month sentence and a $4.3 billion corporate penalty. Readers are asked to accept a single framing in the memoir. Another is provided by Xu’s thread and the congressional investigations into the World Liberty Financial arrangements that preceded Trump’s pardon.

Xu stated he had no interest in relitigating old disputes, even though he proceeded to do so with substantial documentation. It’s still unclear whether this dispute escalates further or whether both men eventually step down. It is evident that the original story has been amplified by a book that was intended to reframe it. A careful image rehabilitation exercise would typically work very hard to avoid the kind of contested public record that the memoir has found itself in due to the conflict with Xu. This is not how the first week of publication was supposed to go, regardless of what CZ intended when he wrote the book on a federal prison terminal between $0.05 messages—the prison origin story is actually one of the more striking details of the entire episode.
