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
| NYA (NYA) Up or Down on May 14? | 52% YES | 49% NO |
The NYSE Composite Index (NYA) will close on Thursday, 14 May 2026, and this market resolves based on whether that closing price exceeds the prior trading day's close. The current order book on Polymarket reflects a 52% implied probability for an up move, suggesting traders view the outcome as marginally more likely to favour gains than losses on that specific day. This probability is formed through continuous trading activity and represents the aggregated positioning of market participants pricing single-day directional movement in a broad-based equity index.
Single-day equity index movements are inherently difficult to predict with conviction, which typically results in probabilities clustering near 50% for directional bets. Historical analysis of the NYA shows roughly even distributions of up and down days across most periods, with daily moves influenced by overnight developments, macroeconomic data releases, and shifts in risk sentiment. The 52% lean toward "Up" suggests marginal bullish positioning rather than strong directional conviction, consistent with how prediction markets typically price binary daily outcomes when fundamental catalysts remain uncertain.
Traders monitoring this market should track scheduled economic releases in the days preceding 14 May 2026, including employment data, inflation reports, and Federal Reserve communications that could shift equity sentiment. Corporate earnings announcements and geopolitical developments in early May will also inform positioning. The settlement window closes at 20:00 UTC on the resolution date, allowing traders to adjust positions based on intraday price action before final settlement against the official NYSE closing price.
This market settles from the official outcome published at https://www.wsj.com/market-data/stocks. 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 "NYA (NYA) Up or Down on May 14?" 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 $39 of resting liquidity puts this market in the below the median by volume for nya 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 52%. 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.
