Resolution criteria on PolyGram: This market will resolve to 'Yes' if the identity of Satoshi Nakamoto, the pseudonymous creator or creators of Bitcoin, is definitively proven between market creation and the listed date, 11:59 PM ET. Otherwise, this market will resolve to 'No'. The resolution source for this market will be definitive evidence confirming the identity of Satoshi Nakamoto, such as a transfer from one of the original Satoshi wallets. However, a credible consensus of reporting will also be used.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.
Market outcomes
| April 30 | 0% YES | 100% NO |
| June 30 | 1% YES | 99% NO |
| December 31 | 6% YES | 95% NO |
Satoshi Nakamoto's identity remains unconfirmed nearly sixteen years after Bitcoin's 2009 launch, despite numerous claims and investigations. The market settles to Yes only if definitive proof emerges—either through cryptographic evidence such as a transaction from an original Satoshi wallet, or through credible consensus reporting. The 0% implied probability on Polymarket's order book reflects the extreme difficulty of proving identity for someone who has maintained operational security across multiple decades and jurisdictions.
Historical precedent suggests such revelations rarely occur without voluntary disclosure. The cases of Ross Ulbricht (Silk Road) and Edward Snowden involved law enforcement and whistleblowing respectively, but neither parallels the cryptographic anonymity Satoshi maintained. Cypherpunk culture, which birthed Bitcoin, was explicitly designed to enable pseudonymous activity. The longer someone remains unidentified, the lower the probability of accidental exposure becomes, as digital forensics improve but so too do the methods of those seeking to remain hidden.
Traders should monitor developments in blockchain forensics, regulatory investigations into early Bitcoin wallets, and any statements from figures historically associated with Bitcoin's development. Recent reporting from investigative journalists periodically surfaces new theories linking Satoshi to known developers, yet none have achieved the definitive proof required for settlement. The market's zero probability reflects that no credible catalyst currently exists on the horizon before the 2026 deadline, and the burden of proof remains extraordinarily high.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
The mechanics for trading "Satoshi's identity be proven by...?" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$48K in lifetime turnover and $13K of resting liquidity puts this market in the above the median by volume for pop culture contracts on PolyGram. Order-book depth is modest — expect a couple of cents of slippage on $1k+ trades.
Last 24 hours alone saw $89 in turnover, consistent with the market's lifetime daily-average pace.
The market has been open for around a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a 2-hour dispute window opens, and if uncontested the payout is final. Contested outcomes escalate to UMA token holders.
This prediction market is scheduled to close on 31 December 2026. After the resolving event occurs, settlement typically clears within 24 hours once the UMA optimistic oracle confirms the outcome. All payouts are in USDC on the Polygon network.

When the outcome is determined, winning YES shares pay out $1.00 each in USDC, while losing shares pay $0. Settlement is handled by the UMA optimistic oracle on Polygon — a proposer submits the result, a two-hour dispute window opens, and if uncontested, payouts are distributed automatically. You can withdraw your winnings to any Polygon wallet.
Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
