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, 3:55AM-4:00AM ET | 0% YES | 100% NO |
This market resolves based on whether Bitcoin's price according to Chainlink's BTC/USD data stream is higher or equal at 4:00AM ET on 8 May 2026 compared to 3:55AM ET the same morning—a five-minute window. The 0% implied probability on Polymarket's order book reflects the extreme difficulty of profitable prediction over such a compressed timeframe. Five-minute price movements in Bitcoin are driven almost entirely by microstructure dynamics: order flow imbalances, algorithmic execution, and latency arbitrage rather than fundamental information. Historical analysis of similar ultra-short-duration markets shows that crowd-implied probabilities near 0% or 100% typically indicate either genuine information asymmetry or, more commonly, rational market participants declining to commit capital where transaction costs and slippage exceed expected returns.
The catalysts relevant to this window are limited to real-time market microstructure. Bitcoin's overnight volatility in May 2026 will depend on concurrent activity across major exchanges and whether any macroeconomic data releases or regulatory announcements occur in the preceding hours. Chainlink's BTC/USD feed aggregates price data from multiple sources with a slight lag, meaning the resolution price reflects market consensus rather than a single exchange's snapshot. Traders should note that five-minute windows often see mean reversion following larger moves, though this pattern is neither consistent nor exploitable after accounting for trading costs. The current order book formation suggests minimal liquidity at either outcome, typical for markets where the expected value of participation is negative for most participants.
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, 3:55AM-4:00AM ET" 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.
$114K in lifetime turnover and $0 of resting liquidity puts this market in the top 30% by volume for up or down 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 0%. 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.
