Resolution criteria on PolyGram: This market will resolve to "Up" if the BNB 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 BNB/USD data stream available at https://data.chain.link/streams/bnb-usd. Please note that this market is about the price according to Chainlink data stream BNB/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
| BNB Up or Down - May 31, 1:15AM-1:20AM ET | 100% YES | 0% NO |
This market tracks whether BNB's price on the Chainlink BNB/USD data stream will be higher or equal at 1:20AM ET on 31 May 2026 compared to 1:15AM ET that same morning—a five-minute window. The 100% implied probability reflects the order book's current assessment on Polymarket, where traders are pricing an extremely high likelihood of either a price increase or flat movement during this brief intraday period.
Five-minute price movements in major cryptocurrencies like BNB are historically volatile and difficult to predict with certainty, yet the market's probability distribution suggests traders view downward movement as negligible within this specific window. Historical precedent shows that ultra-short-term crypto price predictions often reflect current momentum and bid-ask dynamics rather than fundamental shifts. The extreme probability skew indicates either strong conviction about near-term upward pressure or minimal trading activity establishing a thin order book where small positions have outsized influence on implied odds.
Traders should monitor BNB's broader market conditions in the hours preceding the settlement window, including Bitcoin's price action and any announcements from Binance or regulatory developments that might affect sentiment. The Chainlink data stream's specific pricing methodology matters here—resolution depends on their oracle's reported BNB/USD rate rather than spot exchange prices, so understanding any potential discrepancies between Chainlink's feed and live market quotes becomes relevant. Liquidity conditions on major BNB trading pairs during Asian trading hours (when this window falls) will influence actual price movement.
This market settles from the official outcome published at https://data.chain.link/streams/bnb-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.

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.
