Nashville SC win the 2026 MLS Cup priced at 21.5% on Polymarket, up 4.7 points, on $349K traded

Nashville SC’s contract to win the 2026 MLS Cup was priced at 21.5% on Polymarket, up 4.7 probability points, with $349K traded, according to PredictionBubbles’ movers listing. The contract appeared among the board’s upward sports moves, rather than as its lead item.

How the move is measured

PredictionBubbles compares prices over 24 hours and updates its rankings every 15 minutes using data from Polymarket and Kalshi. The supplied snapshot records venue prices read on 27 Oct 2026, 08:13 UTC; the accompanying headline was published Oct 27, 2026 · 4:39 AM ET.

The board orders markets by the size of their probability-point changes, not their relative percentage gains. Nashville’s increase therefore represents a 4.7-point shift in the market’s assessment—not a 4.7% relative rise. Trading volume provides context but does not affect that ranking.

What the listing establishes

According to PredictionBubbles, the ranking covers 2,048 markets lasting longer than 14 days, excluding same-week fixtures. Only open contracts with a valid 24-hour price comparison qualify. Its broader movers table displays the top 150 of 504 markets that changed by at least one probability point.

The supplied material does not identify a Nashville-specific development behind the increase. It establishes a price change and reported trading volume, but does not provide the contract’s order-book depth or explain whether new information or trading activity drove the repricing.

What it means for prediction markets

• The signal is a higher market price: Nashville’s implied probability reached 21.5% after a 4.7-point increase over the comparison window. That change is not independent confirmation of its championship prospects.
• Volume and liquidity are different measures: The reported $349K traded adds context, but the supplied material does not establish how much trading the market could absorb without moving.
• The catalyst remains unverified: The listing alone does not support attributing the move to a match result, team announcement or other specific event.
