A Kalshi contract on Matteo Berrettini winning was priced at 87.0%, up 23.0 probability points, with $719K traded, according to the supplied market update. PredictionBubbles’ Oct. 26, 13:43 UTC snapshot placed the contract among its largest upward sports movers.
The figures show a substantial repricing, but the supplied material does not identify the event, opponent or contract settlement terms. It also provides no explanation for the change.
How the move is measured
According to PredictionBubbles, its movers board compares market-implied probabilities over 24 hours using prices from Kalshi and Polymarket. Rankings reflect the size of the probability-point change, rather than the relative percentage increase; trading volume does not affect a market’s position.
The supplied page carries a later refresh time of 26 Oct 2026, 14:13 UTC. It describes a universe of 2,003 markets lasting longer than 14 days, excluding same-week fixtures. Only open contracts with a valid day-earlier comparison qualify, and the board updates every 15 minutes.
What the available figures establish
The $719K traded figure adds activity context to Berrettini’s price increase, but the supplied excerpt does not include his individual market card or specify the period covered by that amount. Nor does it establish whether the 87.0% price persisted into the later snapshot.
PredictionBubbles distinguishes changes in pricing from evidence about the underlying outcome. Its methodology notes that moves can reflect news, trading in thin order books or participants responding to one another; the available material does not establish which, if any, drove this contract.
What it means for prediction markets
Magnitude: The reported increase is 23.0 probability points, not a 23.0% relative gain.
Timing: The Berrettini summary references 13:43 UTC, while the supplied page was refreshed at 14:13 UTC. The two snapshots should not be treated as interchangeable.
Interpretation: The 87.0% price records market expectations, not a confirmed result. Missing event details and settlement terms limit further assessment.
Activity: The reported $719K traded provides context, but does not by itself establish order-book depth or explain the repricing.
