Vancouver Whitecaps FC win the 2026 MLS Cup priced at 13.0% on Polymarket, down 5.5 points, on $408K traded

Vancouver Whitecaps FC’s contract to win the 2026 MLS Cup was priced at 13.0% on Polymarket, down 5.5 probability points over 24 hours, with $408K traded, according to PredictionBubbles’ movers listing. The figures were reported on Oct 26, 2026, at 2:24 PM ET.

PredictionBubbles placed the Vancouver contract among declining sports markets. The supplied material does not identify a match result, team announcement or other specific catalyst for the repricing.

How the move is measured

PredictionBubbles compares prices from Polymarket and Kalshi over a 24-hour window, updating its board every 15 minutes. The supplied snapshot was read from the venues on 26 Oct 2026 at 18:18 UTC.

The board orders contracts by the absolute change in implied probability, rather than their relative percentage change. Vancouver’s decline is therefore a 5.5-point move—not a 5.5% decrease. Trading volume provides context but does not affect a contract’s position in the ranking.

Scope and limits

According to PredictionBubbles, the board covers 1,998 markets with lifespans longer than 14 days and excludes same-week fixtures. Only open contracts with a valid 24-hour price comparison qualify. Its main table displays the top 150 of 541 markets that moved at least one probability point.

Those filters make the listing a measure of repricing within a defined market universe, not a comprehensive assessment of sports outcomes. The $408K traded figure adds activity context, but the supplied material does not establish order-book depth or explain why traders lowered Vancouver’s implied championship probability.

What it means for prediction markets

• Lower market-implied chance: The 13.0% price reflects a weaker assessment of Vancouver Whitecaps FC winning the 2026 MLS Cup than 24 hours earlier, not a settled outcome.
• Movement and activity are separate: The 5.5-point decline determines the contract’s movement ranking; the $408K traded figure does not.
• The catalyst remains unidentified: The listing documents a price change, but the supplied reporting does not connect it to a specific development.
• Timing matters: These figures describe a dated snapshot on a board refreshed every 15 minutes, rather than a fixed probability.
