Former Binance CEO Changpeng Zhao, better known as CZ, and OKX CEO Star Xu have entered a public dispute on X that quickly escalated from questions about CZ’s past narrative to a $1 billion challenge.
In the first part of the exchange, Star Xu said he wanted to revisit CZ’s long-circulated story about selling a house to buy Bitcoin, raising questions about how that account was presented and whether key personal details behind it had been left out.
Star Xu Challenges CZ’s Divorce Claim
The dispute then moved further into personal territory. In a follow-up post, Star Xu wrote that he would publicly apologize if CZ could produce a divorce agreement signed by both parties as of today. Xu argued that if such a document could not be shown, then describing himself as divorced in media appearances and in his book would be misleading to the public.
CZ Responds With a $1 Billion Bet
CZ answered the accusation directly. In his response, CZ said he is officially divorced but would not post legal documents online out of respect for his former wife’s privacy. He also said he was willing to bet $1 billion, or any amount chosen by the other side, on the truth of his statement. According to CZ, the matter could be verified privately through lawyers rather than through documents published on social media.
The Dispute Expands Into Corporate Conduct
The exchange did not stop there. In another post, Star Xu argued that both OKX and Binance are reviewed by multiple regulators and suggested it was inappropriate for the ultimate beneficial owner of a regulated company to publicly propose a $1 billion bet. That response pushed the argument beyond personal accusations and into questions about executive conduct and corporate responsibility.
At the center of the latest clash are two connected issues: Xu’s attempt to challenge the truth behind CZ’s well-known “sell a house to buy Bitcoin” story, and the more explosive disagreement over whether CZ’s public divorce claim can be backed by the type of documentation Xu demanded.
For now, the controversy is being driven almost entirely by public posts on X. The personal claims involved in the dispute have not been independently verified through public records, which means the current episode remains a high-profile social media confrontation rather than a formally documented legal development.
The latest back-and-forth adds a new personal layer to tensions between two of crypto’s best-known exchange figures. What started as a challenge to CZ’s past narrative has now turned into a broader public fight over credibility, privacy, and the limits of what industry leaders are willing to say in full view of the market.
