The Ole Miss win contract on Kalshi stood at a market-implied probability of 41.0%, down 1 percentage point over 24 hours, with $930K traded in the Oct 23, 2026 · 1:54 PM ET snapshot. According to PredictionBubbles, the contract appears among sports markets approaching resolution, with 3 days remaining.
The supplied material does not identify Ole Miss’s opponent, the sport or the contract’s full settlement conditions. It also provides no explanation for the probability decline, limiting what can be concluded about the move beyond the change in traders’ pricing.
According to PredictionBubbles, its sports page covers 573 open markets: 210 on Kalshi and 363 on Polymarket. The embedded visualization displays the 300 largest by traded volume, while the full board covers the entire tracked set. Its coverage includes individual games, series, championships and season totals.
The site separates markets by trading activity, price movement and approaching deadlines. Its movement ranking uses the absolute probability change over the previous 24 hours, while its volume ranking uses total turnover. Contracts without a dependable resolution deadline are excluded from the ending-soon list.
PredictionBubbles republishes exchange data every 15 minutes, although trading on the venues continues between updates. The displayed probability refers to the first listed outcome: for example, a contract priced at 70¢ represents a 70% market-implied probability. The site describes volume as total trading reported by the venue, rather than a measure of the size of a probability move.
For context, PredictionBubbles identified the Shakhtar Donetsk contract to win the 2026-27 UEFA Champions League Championship as its most-traded open sports market at the latest refresh, with $34.6M traded on Polymarket. PredictionBubbles is an information service displaying prices from the two exchanges; it does not take wagers, hold funds or provide trading accounts.
Polymarket’s contract on whether the U.S. will record at least 7,500 measles cases in 2026 was priced at 22.5%, down 4.5 percentage points, with $219K traded, in the supplied market update published Oct 23, 2026, at 1:54 PM ET.
The figures show traders assigning a lower probability to the threshold being reached. They do not establish any change in reported measles cases: the supplied material contains no case-count update or public-health announcement explaining the move.
According to predictionbubbles.net, its market-movers tracker measures probability-point changes over 24 hours, using prices from Polymarket and Kalshi and refreshing every 15 minutes. The supplied page records a venue-data snapshot at 23 Oct 2026, 17:39 UTC.
The accompanying news summary identified no significant new platform headline in the preceding 30 minutes. Its search results instead resurfaced a Pentagon memo concerning nonpublic information; the material provides no connection between that memo and the measles contract.
The $219K trading figure offers context, but the supplied excerpt does not include the contract’s order-book depth, probability history or settlement criteria. According to predictionbubbles.net, trading volume and liquidity provide context for price changes but do not determine its movers ranking.
