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 - June 1, 4:55AM-5:00AM ET | 100% YES | 0% NO |
This market resolves based on whether the Chainlink ETH/USD data feed records a higher price at 5:00AM ET on 1 June 2026 than at 4:55AM ET that same morning—a five-minute window capturing intraday volatility. The settlement relies specifically on Chainlink's oracle pricing rather than spot exchange data, which can diverge slightly during low-liquidity periods.
Five-minute price movements in cryptocurrency are predominantly driven by order flow imbalances and algorithmic trading rather than fundamental news. Historical analysis of similar ultra-short-window markets shows that without scheduled announcements or exchange maintenance windows, these outcomes distribute roughly evenly between up and down moves. The current 100% implied probability on Polymarket's order book suggests either extremely thin liquidity at the ask side or a data feed anomaly; such extreme probabilities on random intraday windows typically reflect market microstructure rather than genuine conviction.
Traders should monitor whether any Ethereum-related announcements are scheduled near the resolution window, though major news typically occurs during US business hours rather than pre-market periods. Chainlink feed health and any planned maintenance on major exchanges during this window would be material. The five-minute timeframe means that large spot trades or futures liquidations cascading through the market could influence the Chainlink price feed's reading, though such events are unpredictable. Given the settlement window is nearly two years away, current pricing may simply reflect minimal trading activity rather than meaningful probability assessment.
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 - June 1, 4:55AM-5:00AM 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.

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.
