Cavaliers vs. Hawks priced at 27.5% on Polymarket, down 21.0 points, on $2.0M traded

The “Cavaliers vs. Hawks” market on Polymarket stood at a 27.5% implied probability, down 21.0 percentage points over 24 hours, with $2.0M traded, according to the supplied PredictionBubbles snapshot. The board defines its displayed probability as the price of a market’s first outcome; the supplied material does not identify which outcome that is for this matchup.

A reused snapshot, not a fresh update

The figures come from PredictionBubbles’ Oct. 30, 02:30 UTC crawl, which covered 579 open sports markets with $779.9M traded. The summary explicitly discloses that this was the same crawl used for the Oct. 29 2224 edition. The story’s publication timestamp—Oct 29, 2026 · 10:39 PM ET—therefore should not be read as evidence of a newer market observation.

According to PredictionBubbles, its sports feed refreshes every 15 minutes and combines 237 Kalshi markets with 342 Polymarket markets. The exchanges trade continuously, so a published board snapshot can differ from prices subsequently available on either venue.

Movement and volume measure different things

PredictionBubbles separates its ranking of absolute 24-hour probability changes from its ranking of total traded volume. The Cavaliers–Hawks figures describe both a substantial price decline and accumulated trading activity, but the supplied material gives no explanation for the move. It also does not establish that the $2.0M was traded during that 24-hour period.

For broader context, PredictionBubbles identified the Polymarket contract asking whether Shakhtar Donetsk will win the 2026-27 UEFA Champions League Championship as its most-traded open sports market at the last refresh, with $37.3M traded. That volume ranking is separate from the board’s list of biggest probability movers.

What it means for prediction markets

• Outcome identification matters: The 27.5% reading applies to the first listed outcome, not necessarily to a Cavaliers win or a Hawks win.
• The decline is in percentage points: The reported 21.0-point move measures the change in implied probability over 24 hours, not a 21.0% relative decline.
• Repeated data is not a second signal: The disclosed reuse of the crawl means the later edition does not independently confirm further movement.
• Cross-venue comparisons require care: According to PredictionBubbles, related Kalshi and Polymarket contracts can differ in wording and resolution rules.
