Georgia’s Kalshi contract to win the College Football Playoff National Championship was priced at 18.0%, up 2.0 percentage points, with $4.0M traded, according to PredictionBubbles’ sports-board snapshot. The supplied summary identifies the board reading as Oct. 28, 05:25 UTC.
PredictionBubbles defines its probability-change measure as the move over the previous 24 hours. Georgia’s increase therefore reflects a higher market-implied championship chance over that period, rather than a change in an independently calculated forecast.
The $4.0M figure represents total traded volume, not trading confined to the past day. The supplied material does not identify a specific development behind Georgia’s price increase or provide its ranking among championship contenders.
According to PredictionBubbles, its sports page tracks 557 open markets across Kalshi and Polymarket: 227 on Kalshi and 330 on Polymarket. Its embedded display includes the 300 largest markets by volume, while the full board covers all 557.
PredictionBubbles refreshes its data every 15 minutes, although trading on the underlying venues is continuous. The site aggregates exchange-published prices and does not accept wagers, hold funds or offer accounts.
The board’s largest sports market by total traded volume at the last refresh was the Polymarket contract on whether Shakhtar Donetsk would win the 2026-27 UEFA Champions League Championship, with $36.5M traded, according to PredictionBubbles. That volume ranking is separate from the board’s ranking of absolute probability moves over 24 hours.
Polymarket’s contract on whether Spider-Man: Brand New Day will be the top-grossing movie of 2026 was priced at 93.5%, up 2.0 percentage points, with $735K traded, in the supplied market snapshot published Oct 28, 2026 · 1:24 AM ET.
The price represents a strong market-implied likelihood, rather than confirmation of the film’s eventual box-office ranking. The supplied material contains no box-office receipts or competing films’ results against which to assess that expectation.
The accompanying news summary reported no significant new platform headline in the preceding 30 minutes. Its search surfaced only coverage already used on Oct. 27, referring to the NBA preferred-partner deal and an incomplete reference to CFTC-NBA news. That summary does not establish a film-specific explanation for the contract’s move.
According to predictionbubbles.net, its culture-market board reports probability changes over the last 24 hours and refreshes data every 15 minutes. It defines traded volume as cumulative trading activity where published by the venue—not the amount traded during the latest price move.
The outlet aggregates culture contracts from Kalshi and Polymarket, with 48 markets listed in the supplied page: 12 from Kalshi and 36 from Polymarket. It also cautions that related contracts across venues may use different wording and settlement rules. The supplied page does not include the Spider-Man contract’s specific resolution criteria.
