Club Brugge jumps 55 points to 64% as Inter falls 70 points to 8% on Kalshi

Club Brugge climbed 55 probability points to 64.0% on Kalshi, while Inter dropped 70 points to 8.0%, marking the sports board’s sharpest repricing in the supplied Oct 13, 2026 update. Reported trading volume stood at $1.1M for Club Brugge and $1.2M for Inter.

Atletico was listed at 99.0%. The update, published at 4:54 PM ET, does not provide the remainder of that entry or identify the exact outcomes covered by these contracts, limiting conclusions about what drove the moves.

Large moves, limited contract detail

According to predictionbubbles.net, its board measures probability changes over the preceding 24 hours in points, rather than percentage changes. The Club Brugge and Inter figures therefore describe substantial shifts in market pricing, not proportional increases or decreases in their odds.

The supplied material does not establish whether the contracts concern individual matches, qualification or a championship. Nor does it identify a news event behind the repricing. The opposing moves alone are insufficient to conclude that traders were responding to the same development.

Reading the volume correctly

According to predictionbubbles.net, displayed volume represents total trading where the venue supplies that information. The $1.1M and $1.2M figures should not be treated as money traded solely during the latest 24-hour window, or as the value of positions still open.

PredictionBubbles aggregates Kalshi and Polymarket prices and refreshes its data every 15 minutes. Its probabilities reflect contract prices, not verified chances of an outcome; even Atletico’s 99.0% reading remains a market assessment rather than a settled result.

What it means for prediction markets

• Contract wording is essential: Without the exact questions and settlement rules, the Club Brugge, Inter and Atletico readings cannot reliably be compared as competing outcomes.
• Movement and volume measure different things: The 55-point rise and 70-point decline capture repricing; the reported volumes capture cumulative trading activity.
• The catalyst remains unconfirmed: The available material supports a sharp change in prices, but not an explanation for it.
