Resolution criteria on PolyGram: This market will resolve to "Up" if the XRP 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 XRP/USD data stream available at https://data.chain.link/streams/xrp-usd. Please note that this market is about the price according to Chainlink data stream XRP/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
| XRP Up or Down - May 31, 11:20AM-11:25AM ET | 100% YES | 0% NO |
This market resolves based on whether XRP/USD on Chainlink's data feed closes at or above its opening level during a five-minute window on 31 May 2026 at 11:20–11:25 AM Eastern Time. The current order book on Polymarket reflects a 100% implied probability for "Up," indicating traders are pricing near-certainty that the price will not decline during this specific five-minute interval. This extreme probability typically emerges when the settlement window is either imminent or when market participants perceive minimal downside risk within such a compressed timeframe.
Five-minute price movements in XRP historically exhibit low volatility relative to daily or weekly swings, particularly during regular trading hours when liquidity is stable. Comparable micro-window markets on XRP have shown that achieving 100% probability reflects the statistical rarity of sharp reversals within minutes rather than fundamental conviction about directional bias. The Chainlink feed aggregates prices from multiple exchanges, which can introduce minor latency differences that occasionally create arbitrage opportunities between the feed timestamp and spot market execution.
Traders monitoring this market should note that XRP's price action on 31 May will depend on broader cryptocurrency market conditions and any regulatory announcements affecting the asset. Recent volatility in XRP has been tied to SEC litigation developments and institutional adoption signals. The five-minute window itself carries execution risk; any flash crash or feed anomaly during 11:20–11:25 AM ET could trigger resolution, though such events remain statistically uncommon during standard market hours.
