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 9, 12:55AM-1:00AM ET | 100% YES | 0% NO |
This market captures Bitcoin's price movement across a five-minute window on 9 May 2026, using Chainlink's BTC/USD oracle data as the settlement source. The resolution hinges on whether the price at 1:00AM ET meets or exceeds the price at 12:55AM ET—a narrow timeframe that isolates intraday volatility rather than directional conviction. The current 100% implied probability on Polymarket's order book reflects either extreme confidence in upward movement or minimal liquidity at the ask, a distinction worth examining before committing capital.
Five-minute Bitcoin price windows historically exhibit near-random walk characteristics, with resolution outcomes clustering around 50-50 splits across comparable micro-timeframe markets. The 100% reading suggests either a significant imbalance in order flow or a thin book where small bids have moved the probability ceiling. Comparable ultra-short-duration markets on Polymarket typically show probabilities gravitating towards 50% as settlement approaches, particularly when the underlying asset trades continuously without scheduled halts.
Traders should monitor Chainlink's data feed stability and any scheduled maintenance windows that could affect price reporting between 12:55AM and 1:00AM ET. Bitcoin spot markets across major exchanges—Coinbase, Kraken, Binance—will determine the oracle's input, with any flash crashes or liquidity events during this specific five-minute window potentially creating resolution disputes. The absence of major economic announcements or cryptocurrency-specific catalysts scheduled for that precise window means price movement will likely reflect ambient market microstructure rather than fundamental shifts.
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 9, 12:55AM-1:00AM 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.
$69K in lifetime turnover and $0 of resting liquidity puts this market in the above the median by volume for bitcoin contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
Last 24 hours alone saw $69K in turnover, well above the lifetime daily-average for this market — a clear sign of news catalysing trader activity right now.
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.

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.
