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 4, 5:30PM-5:45PM ET | 100% YES | 0% NO |
This market resolves based on whether XRP/USD on Chainlink's data feed closes higher or flat during a fifteen-minute window on 4 May 2026 from 5:30PM to 5:45PM ET. The current order book on Polymarket reflects a 100% implied probability for an upward or flat close, indicating traders are pricing near-certainty that XRP will not decline during this specific interval. Such extreme probabilities on short-duration price windows typically emerge when liquidity is thin or when the market structure itself creates asymmetric risk—a fifteen-minute window offers minimal time for significant adverse price movement.
Historical precedent suggests that ultra-short timeframe crypto markets often trade at extreme probabilities due to the difficulty of orchestrating coordinated downward pressure within such compressed periods. Comparable fifteen-minute resolution markets on major assets have occasionally resolved contrary to consensus when unexpected news breaks or when thin order books amplify minor sell-side pressure. The Chainlink data feed itself introduces a dependency on oracle reporting accuracy and timeliness, which has occasionally lagged spot market movements by seconds during volatile periods.
Traders should monitor XRP's broader market conditions in the hours preceding the window, including any regulatory announcements or macroeconomic data releases that could trigger volatility. The settlement window closes at 21:45 UTC on 4 May, allowing approximately sixteen hours from the resolution period for Chainlink data to be finalised and confirmed. Any scheduled maintenance on Chainlink infrastructure or unexpected data feed disruptions could affect settlement mechanics.
This market settles from the official outcome published at https://data.chain.link/streams/xrp-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 "XRP Up or Down - May 4, 5:30PM-5:45PM 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.
$3K in lifetime turnover and $0 of resting liquidity puts this market in the below the median by volume for crypto prices contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
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.
