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, 7:00PM-7:05PM ET | 0% YES | 100% NO |
This market resolves based on whether Bitcoin's price according to Chainlink's BTC/USD data feed is higher or unchanged at 7:05PM ET on 8 May 2026 compared to 7:00PM ET that same evening. The five-minute window captures intraday volatility during US evening hours, a period typically characterised by lower trading volumes than Asian or European sessions. Resolution hinges entirely on Chainlink's oracle data rather than spot market prices, introducing a potential basis between this contract and actual exchange trading.
The 0% implied probability on Polymarket's order book reflects extreme confidence in a downward movement during this specific window. Such extreme probabilities on short-duration contracts often emerge when liquidity is sparse or when the order book has been shaped by a small number of positions. Five-minute price movements in Bitcoin are largely unpredictable without material news catalysts; historical precedent suggests that micro-timeframe directional bets typically reflect either technical positioning or the absence of competing liquidity rather than fundamental conviction.
Traders should monitor whether any scheduled announcements, regulatory filings, or macroeconomic data releases fall within or immediately precede the settlement window. Bitcoin's price action on any given evening often correlates with US equity futures and Treasury yields, particularly during periods of heightened volatility. The Chainlink feed's specific methodology and any potential latency between spot prices and oracle reporting could affect settlement outcomes, making familiarity with the data stream's mechanics relevant to position assessment.
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, 7:00PM-7:05PM 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.
$194K 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 $194K 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 0%. 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.
