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, 8:40PM-8:45PM ET | 100% YES | 0% NO |
This market tracks whether Bitcoin's price on the Chainlink BTC/USD data stream will close higher or flat over a five-minute window on 9 May at 8:40–8:45 PM ET. The settlement relies exclusively on Chainlink's oracle feed rather than spot exchange prices, which can occasionally diverge during periods of network congestion or data latency. The current orderbook on Polymarket shows 100% implied probability for an up move, reflecting either extreme confidence in upward momentum or minimal liquidity at current pricing levels.
Five-minute price windows in Bitcoin typically resolve "up" roughly 50–52% of the time under normal market conditions, given the asset's intraday volatility and the randomness of tick-level price action. The 100% crowd probability here is unusually skewed and suggests either that traders expect a significant directional catalyst immediately before the window, or that the orderbook depth is shallow enough that a single large order has anchored sentiment. Historical precedent shows such extreme probabilities in short-window markets often reflect illiquidity rather than genuine conviction about directional moves.
Traders should monitor Bitcoin's spot price action in the hours preceding the window, particularly any major announcements from Federal Reserve officials, significant options expiry events, or large on-chain transfers that might signal institutional positioning. Chainlink's feed aggregates prices from multiple exchanges with a slight lag, so traders familiar with the feed's historical behaviour relative to spot markets may identify arbitrage opportunities if the oracle price diverges from real-time exchange data during the settlement window.
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, 8:40PM-8:45PM 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.
$203K in lifetime turnover and $0 of resting liquidity puts this market in the top 10% 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.
Last 24 hours alone saw $203K 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.

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.
