Resolution criteria on PolyGram: This market will resolve to "Up" if the Bitcoin price at the end of the time range specified in the title is greater than or equal to the price at the beginning of that range. Otherwise, it will resolve to "Down". The resolution source for this market is information from Chainlink, specifically the BTC/USD data stream available at https://data.chain.link/streams/btc-usd. Please note that this market is about the price according to Chainlink data stream BTC/USD, not according to other sources or spot markets.
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
| Bitcoin Up or Down - May 8, 12:25AM-12:30AM ET | 100% YES | 0% NO |
This market captures Bitcoin's price movement across a five-minute window on 8 May 2026, settling against Chainlink's BTC/USD oracle feed rather than spot exchange prices. The settlement window runs from 12:25AM to 12:30AM ET, a period typically characterised by lower trading volumes in US markets, though Bitcoin trades continuously across global exchanges. The current 100% implied probability on the order book reflects either extreme confidence in upward movement or a pricing anomaly given the compressed timeframe and minimal historical volatility expected within five minutes.
Five-minute Bitcoin price movements are inherently difficult to predict with statistical significance. Historical data shows that intraday micro-movements of this scale are largely driven by order flow imbalances and technical bounces rather than fundamental catalysts. The Chainlink oracle aggregates data from multiple exchange sources with a slight lag, meaning the resolution price will reflect a smoothed snapshot rather than any single exchange's tick. This lag structure has occasionally created discrepancies between real-time spot prices and oracle settlements, particularly during volatile periods when exchanges experience brief disconnections.
Traders should monitor whether any scheduled announcements or macroeconomic data releases fall near the settlement window, though such events are unlikely at 12:25AM ET on a Thursday. Network activity, large on-chain transfers, or unexpected regulatory news could theoretically move prices, but the five-minute window provides minimal reaction time. The extreme implied probability warrants scrutiny—such certainty in a micro-timeframe market typically indicates either thin liquidity on the order book or a structural mispricing relative to the underlying volatility regime.
This market settles from the official outcome published at https://data.chain.link/streams/btc-usd. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.
The mechanics for trading "Bitcoin Up or Down - May 8, 12:25AM-12:30AM ET" are the same as any other PolyGram crypto-price 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.
$140K in lifetime turnover and $0 of resting liquidity puts this market in the above the median by volume for crypto contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
The market has been open for under 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.
As of today, traders on Polymarket price this outcome at 100%. The number updates continuously as the order book clears. PolyGram mirrors the same live odds with locale-aware formatting and USDC settlement.

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.
