Resolution criteria on PolyGram: This market will resolve to "Up" if the Ethereum 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 ETH/USD data stream available at https://data.chain.link/streams/eth-usd. Please note that this market is about the price according to Chainlink data stream ETH/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
| Ethereum Up or Down - May 3, 11:45PM-12:00AM ET | 100% YES | 0% NO |
This market settles based on whether Ethereum's price according to Chainlink's ETH/USD data feed is higher or equal at 12:00AM ET on 4 May compared to 11:45PM ET on 3 May—a fifteen-minute window. The current 100% implied probability on Polymarket's order book reflects extreme confidence in upward movement or flat price action over this specific interval. Such compressed timeframes create unusual market dynamics; the probability is being formed by traders pricing in either technical momentum, scheduled events, or simply the statistical likelihood that price remains stable during a quarter-hour window.
Fifteen-minute price movements in cryptocurrency are typically driven by intraday volatility rather than fundamental shifts. Historical precedent suggests that such tight windows rarely resolve to "Down" unless a sharp liquidation cascade or flash crash occurs. The 100% probability on the order book may indicate either thin liquidity at the extremes or genuine consensus that downward movement is improbable. Comparable ultra-short-window markets on Polymarket have shown that extreme probabilities often reflect the difficulty of pricing tail-risk events rather than certainty of outcome.
Traders should monitor Ethereum's technical setup heading into the settlement window, including support levels and order flow. Major announcements affecting broader crypto sentiment—such as regulatory news or macroeconomic data releases—could theoretically trigger sharp moves, though such events are less predictable at intraday frequencies. The Chainlink data feed itself is the sole arbiter; spot market prices across exchanges may diverge slightly from Chainlink's aggregated pricing, creating potential basis risk for traders relying on alternative sources.
This market settles from the official outcome published at https://data.chain.link/streams/eth-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 "Ethereum Up or Down - May 3, 11:45PM-12:00AM 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.
$7K in lifetime turnover and $0 of resting liquidity puts this market in the below the median 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.
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.
Resolution is sourced from https://data.chain.link/streams/eth-usd. Settlement is executed by the UMA optimistic oracle on Polygon, with a 2-hour dispute window before payouts clear.
This prediction market is scheduled to close on 4 May 2026. After the resolving event occurs, settlement typically clears within 24 hours once the UMA optimistic oracle confirms the outcome. All payouts are in USDC on the Polygon network.

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.
