Polymarket has opened a new market on the identity of Bitcoin creator Satoshi Nakamoto. The market follows the coming release of “Finding Satoshi,” an online documentary due on April 22. Early betting placed Adam Back in front with 56% odds. The new pool brings a long-running crypto mystery back into public view.

Polymarket market puts Satoshi debate back in focus

The market lets users bet on who the documentary will name as Satoshi. Traders can choose from several well-known names tied to past theories. Adam Back held the top spot when the market opened. His odds stood at 56% in early trading.

The documentary is called “Finding Satoshi.” Matthew Miele and Tucker Tooley directed the film. It follows author William Cohan and investigator Tyler Maroney for four years. Their search combines interviews, records, and technical analysis.

The film also looks at Bitcoin’s early years. It tracks how the network grew and gained influence. That broader story frames the search for its creator. The documentary is scheduled to premiere online on April 22.

Michael Saylor is among the people featured in the film. The documentary uses those interviews to test old claims. It also compares public statements with past records. That method is part of the film’s central investigation.

New film enters a long-running search for Bitcoin’s creator

The question around Satoshi’s identity has persisted for nearly two decades. Many reports, books, and films have tried to answer it. None has produced proof that ended the debate. That long history explains interest in the new Polymarket market.

An HBO documentary returned to the issue in October 2024. “Money Electric: The Bitcoin Mystery” pointed to Peter Todd. The case leaned on Todd’s technical background and early Bitcoin work. Todd rejected the claim, and the film failed to win broad support.

Other names still appear often in crypto discussions about Satoshi. Len Sassaman remains one of the most cited candidates. Hal Finney also stays central in many past theories. Both names now appear in the new Polymarket pool.

The new market turns that debate into a live trading event. Each change in odds reflects trader views, not proof. Still, the market offers a clear snapshot of current sentiment. That makes it a fresh measure of public interest.

Adam Back leads market but denies being Satoshi

Back’s lead follows recent reporting that renewed scrutiny of his history. He is a British cryptographer and the creator of Hashcash. Hashcash predates Bitcoin and shares ideas with proof-of-work systems. That link keeps his name close to the Satoshi debate.

New York Times journalist John Carreyrou recently named Back as a leading candidate. The report cited language patterns and old mailing list material. It also referred to records from a 2024 London court case. Timing links around early Bitcoin milestones also drew attention.

Back has repeatedly denied that he created Bitcoin. For now, the public still lacks proof that identifies Satoshi. Arkham estimated Satoshi’s holdings at about 1.1 million Bitcoin. At current prices in the report, that stash was worth about $82 billion.

The mystery also carries financial weight because Satoshi’s coins remain untouched. Those holdings have never moved in a way that proved ownership. Until that changes, most claims will stay open to challenge. That uncertainty helps keep markets and documentaries focused on the question.
