Aidan Mayo’s win contract on Kalshi was priced at 73.0%, with $1.4M traded, in the Oct 22, 2026 · 2:24 PM ET update. According to PredictionBubbles’ most-active listing, the sports contract was among the day’s busiest markets by traded volume.

That placement measures trading activity, not the size of a change in Mayo’s implied chances. The supplied material does not identify his opponent, the fixture date or the contract’s settlement terms.

Activity is not the same as movement

According to PredictionBubbles, its most-active module orders contracts by 24-hour traded volume. That is separate from its main movers ranking, which compares the absolute change in implied probability over 24 hours, expressed in probability points.

The distinction matters for interpreting the Mayo contract. A 73.0% price describes the market’s current assessment, while the $1.4M figure describes trading activity. Neither establishes whether Mayo’s price rose or fell during the day; no contract-specific 24-hour change is included in the supplied material.

A snapshot with limits

PredictionBubbles says it draws prices from Polymarket and Kalshi and updates the board every 15 minutes. The supplied page records a venue-data snapshot of 22 Oct 2026, 18:17 UTC.

Its main movement ranking covers 1,986 markets that live longer than 14 days, excluding same-week fixtures to avoid allowing near-settlement swings to dominate. Those movement-screen rules should not be confused with the separate volume-based listing in which the Mayo contract appears.

What it means for prediction markets

• 73.0% is a price-implied assessment, not a confirmed result. The supplied material provides no match outcome.
• $1.4M traded signals activity, not necessarily repricing. Without a prior price, the direction and magnitude of any change remain unknown.
• Key contract details are absent. The opponent, fixture timing and settlement rules are needed to interpret precisely what the Mayo win contract covers.
