PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Both platforms rely on the same core logic of comparing the closing price on September 14, 2026, to the prior day's closing price, using Pyth data as the primary source.Primary resolution logic: Pyth (https://pythdata.app/explore/Equity.US.NVDA%2FUSD)

Core resolution logic:

Resolution is based on the closing price of NVIDIA (NVDA) on September 14, 2026.
The closing price is compared to the closing price on the most recent prior trading day.
If the September 14th close is higher, the market resolves to 'Up'. If lower, it resolves to 'Down'.
Equal closing prices result in a 50-50 resolution.

Edge cases & clarifications:

No Trading on 9/14: If NVIDIA (NVDA) does not trade during the regular session on September 14, 2026, the market will resolve 50-50.
Pyth Data Failure: If Pyth data is unavailable, the official closing price published by the primary exchange will be used.
Stock Split/Reverse Split: Resolution will be based on split-adjusted prices as displayed on Pyth.

Timing: Resolution will occur after the regular trading hours on September 14, 2026, once the closing price is confirmed from Pyth or the primary exchange.Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.

Polymarket

This market will resolve to "Up" if the Close price for NVIDIA (NVDA) on September 14, 2026 is higher than the Close price for NVIDIA (NVDA) on the most recent prior trading day. This market will resolve to "Down" if the Close price for NVIDIA (NVDA) on September 14, 2026 is lower than the Close price for NVIDIA (NVDA) on the most recent prior trading day. E.g., ordinarily, a market on Monday would refer to the previous Friday for its most recent closing price, unless that Friday were a market holiday, in which case it would refer to Thursday, or the next most recent trading day. If the two specified closing prices are exactly equal, this market will resolve 50-50. Closing prices will be used exactly as published by Pyth, without rounding. If NVIDIA (NVDA) does not trade at all during the regular session, the market will resolve 50-50. For a standard full trading session, the closing price refers to the Pyth "Close" value of the 1-minute candle corresponding to the final minute of regular trading hours on the primary exchange. If either of the relevant days has no valid Pyth Close value for the 1-minute candle corresponding to the end of regular trading hours on the primary exchange, the market will use the last valid Pyth price achieved during the regular trading hours of the primary exchange as the effective closing price. If no valid Pyth price exists for that trading day due to a system outage, data failure, or other technical disruption, the official closing price published by the primary exchange on which the listed security trades will be used to determine the closing price for that day. Only prices achieved during the regular trading hours of the primary exchange on which the listed security trades (typically 9:30 AM – 4:00 PM ET) will be considered. In the event of a stock split, reverse stock split, or similar corporate action affecting the listed security during the listed time frame, this market will resolve based on split-adjusted prices as displayed on Pyth. The resolution source for this market will be Pyth, specifically the "Close" values for the relevant 1-minute candle available at https://pythdata.app/explore/Equity.US.NVDA%2FUSD. Historical 1-minute candles may be accessed by appending a Unix timestamp (seconds) to the Pyth chart URL using the "t=" parameter. Any timestamp within the listed market time frame may be used to view the relevant candle data (e.g., https://pythdata.app/explore/Equity.US.NVDA%2FUSD?t=1773432000).

Opinion

This market will resolve to "Yes" if the official "Close" price for NVIDIA (NVDA) on the trading day specified in the title is strictly higher than the price specified in the title. A "Close" exactly equal to the specified price resolves to "No". If the market is not open on the specified day (exchange holiday or unscheduled closure), or NVIDIA (NVDA) does not trade at all during that day's regular session, this market resolves 50-50 — each side is paid at half value; this is not a refund. In the event of a stock split, reverse stock split, or similar corporate action affecting NVIDIA (NVDA), this market resolves on split-adjusted prices, and the price specified in the title is adjusted proportionally. The resolution source for this market is Yahoo Finance, specifically the NVIDIA (NVDA) "Close" prices available at https://finance.yahoo.com/quote/NVDA/ under "Historical Prices". If that data is unavailable due to an outage or other technical disruption, the official price published by the primary exchange on which NVIDIA (NVDA) trades governs.

Frequently asked questions

Prediction market odds often offer a different perspective than traditional analyst forecasts. While analysts rely on fundamental and technical analysis, this market reflects the collective wisdom of traders who are putting their capital at risk. This can lead to a more accurate prediction, as traders are incentivized to make informed decisions. Currently, the implied probability of the stock going up or down, as reflected in this market, may differ from the average analyst rating. It’s important to consider both sources of information when forming your own opinion on NVIDIA’s future performance.

Polymarket and Opinion can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Prices on Polymarket and Opinion can diverge due to several factors. Each platform attracts a different user base with varying risk appetites and information access. Polymarket might have more sophisticated traders, while Opinion could have a broader range of participants. Furthermore, trading fees and platform-specific rules can influence pricing. Market sentiment can also shift independently on each platform based on news flow or influential traders. These differences contribute to potential discrepancies in the probabilities offered for this market, even though they both address the same underlying question about the NVIDIA stock.
