Infiniti Intelligence Hourly Briefing — Oct 26, 2026 · 3:24 AM ET

Polymarket’s contract on an Iran coup attempt by December 31, 2027 was priced at 27.5%, down 13.5 probability points over 24 hours, with $110K traded. According to PredictionBubbles, the contract ranked among the largest downward moves in its political/election category.

The figures accompanied the Oct 26, 2026 · 3:24 AM ET update. PredictionBubbles’ underlying venue-price snapshot was timestamped 26 Oct 2026, 07:09 UTC; the service updates its board every 15 minutes.

A sharp repricing, without an identified catalyst

The decline shows a lower market-implied probability for the specified outcome, not evidence that a coup attempt has occurred or been prevented. The supplied reporting does not identify a news event or other catalyst behind the move.

The contract’s December 31, 2027 deadline also matters: this is pricing for an outcome over that horizon, rather than a standalone assessment of immediate political instability in Iran. The supplied material does not include the contract’s detailed resolution criteria.

How the move is ranked

According to PredictionBubbles, the board compares prices from Polymarket and Kalshi across 2,043 markets with lifespans longer than 14 days. It ranks eligible open contracts by the absolute size of their 24-hour probability-point changes, excluding those without a valid day-earlier comparison.

Trading volume and liquidity provide context but do not determine that ranking. The $110K traded figure therefore sits alongside the Iran contract’s price decline; it does not, by itself, establish how deep the market was or what drove the repricing.

What it means for prediction markets

• Measure the decline correctly: The reported move is a fall of 13.5 probability points to 27.5%, not a 13.5% relative decrease.
• Separate price action from event evidence: The board documents changing market prices, while the supplied reporting offers no identified catalyst for the Iran move.
• Keep the deadline and rules in view: The outcome concerns a coup attempt by December 31, 2027. Detailed resolution criteria are not included in the supplied material.
• Treat volume as context: The $110K traded figure does not establish liquidity or explain why the probability fell.

The Kalshi market for “Moyuka Uchijima wins” was priced at a 1.0% implied probability, down 18.0 percentage points, with $1.1M traded, in the supplied snapshot published Oct 26, 2026 · 3:24 AM ET.

A sharp move without a confirmed catalyst

The accompanying news-search summary identified no significant new platform headline in the preceding 30 minutes. It provided no fresh reporting explaining the change in Uchijima’s market price.

According to predictionbubbles.net, its sports board measures probability changes over the last 24 hours and reports total traded volume where the exchange makes it available. Those measures describe repricing and accumulated trading activity; they do not establish what prompted a move.

Reading the snapshot

PredictionBubbles says it aggregates prices from Kalshi and Polymarket and refreshes its data every 15 minutes, while trading on the exchanges continues between updates. The supplied price should therefore be read as a snapshot rather than a continuously updated quote.

The supplied material does not identify Uchijima’s opponent, the event, the contract’s resolution terms or the state of play. Without those details, the decline cannot reliably be attributed to a sporting development or interpreted as a confirmed result.

What it means for prediction markets

• Price is not resolution: A 1.0% implied probability indicates traders assigned a low chance to the outcome at the snapshot time; it does not confirm that the contract has settled.
• Volume has limits: The $1.1M figure represents total traded volume, not necessarily money traded during the decline.
• Context remains missing: Contract wording, resolution rules and event status are needed to assess the move beyond its reported size.
