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 11, 6:55PM-7:00PM ET | 50% YES | 50% NO |
This market captures a five-minute window for Ethereum's price movement on 11 May 2026, settling against Chainlink's ETH/USD data feed rather than spot exchange prices. The resolution hinges on whether the closing price at 7:00PM ET exceeds or matches the opening price at 6:55PM ET, a timeframe where intraday volatility and order flow dynamics dominate price discovery.
Five-minute price windows in cryptocurrency typically exhibit mean-reversion characteristics, particularly during regular trading hours when institutional participation is steady. Historical analysis of similar ultra-short-duration markets shows that without significant news events or market dislocations, these windows resolve based on microstructure factors—bid-ask spreads, order book depth, and algorithmic trading patterns. The current 50% implied probability on Polymarket's order book reflects genuine uncertainty; neither directional bias nor technical setup appears decisive for such a compressed timeframe.
Traders should monitor Ethereum's broader market structure in the hours preceding the window, including Bitcoin's trajectory and any macroeconomic data releases scheduled for that afternoon. Chainlink's feed aggregation methodology means the resolution price reflects a time-weighted median across multiple exchange sources, reducing single-venue manipulation risk but introducing slight latency relative to spot markets. Liquidity conditions on major venues and any scheduled smart contract activity or network events would be the primary catalysts affecting price direction during this specific five-minute interval.
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 11, 6:55PM-7:00PM 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.
$0 in lifetime turnover and $5K 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 50%. The number updates continuously as the order book clears. PolyGram mirrors the same live odds with locale-aware formatting and USDC settlement.

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.
