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 4, 12:15AM-12:30AM ET | 100% YES | 0% NO |
This market captures a fifteen-minute window for Ethereum's price movement on 4 May 2026, settling against Chainlink's ETH/USD data feed rather than spot exchange prices. The resolution hinges on whether the closing price at 12:30AM ET meets or exceeds the opening price at 12:15AM ET—a narrow timeframe where intraday volatility typically dominates over directional conviction.
The 100% implied probability on Polymarket's order book reflects an extreme skew toward "Up," suggesting either minimal liquidity on the "Down" side or a structural imbalance in how traders are positioning. Historically, fifteen-minute price windows show near-random walk behaviour; comparable micro-timeframe markets rarely sustain probabilities above 70% without significant event catalysts. The current probability likely reflects thin order depth rather than genuine conviction about price direction, making this a liquidity-driven rather than fundamentals-driven market state.
Traders should monitor Ethereum network activity and broader crypto market moves in the hours preceding the window, though no scheduled announcements typically drive such short-term moves. Chainlink feed latency and any flash crashes on major exchanges could create discrepancies between the feed price and spot markets. The settlement window closing in 2026 allows substantial time for position accumulation, but the fifteen-minute resolution window itself remains subject to ordinary market microstructure noise rather than predictable catalysts.
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 4, 12:15AM-12:30AM 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.
$13K 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.

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.
