The Polymarket contract on whether Avengers: Doomsday will be the top-grossing movie of 2026 was priced at 6.6%, down 3.4 percentage points, with $1.2M traded in the supplied Oct 28, 2026 · 9:54 AM ET snapshot.
The move signals a decline in the market-implied likelihood of the film finishing first. The supplied news-search summary, however, identified no significant new platform headline in the preceding 30 minutes. It does not establish a fresh news catalyst for the price change.
According to predictionbubbles.net, its culture-market board measures probability changes over the last 24 hours and reports total traded volume where the venue makes that figure available. The $1.2M figure should therefore be distinguished from money traded during the decline itself.
PredictionBubbles says its culture coverage currently includes 48 open markets: 12 from Kalshi and 36 from Polymarket. Its data refreshes every 15 minutes, while trading on the underlying venues continues between updates.
The supplied source page explains the board’s methodology but does not include the Avengers: Doomsday contract’s individual listing or resolution terms. The specific price and volume figures come from the supplied headline; the material does not establish the box-office measurement or eligibility rules that will determine the result.
Darian Mensah’s Kalshi contract to win the Heisman Trophy was priced at a 21.0% implied probability, down 2.0 percentage points over 24 hours, with $2.1M traded. The figures accompanied the Oct 28, 2026 · 9:54 AM ET report.
According to PredictionBubbles, its sports board was unchanged at the Oct. 28, 13:26 UTC reading. The supplied material does not identify a news event or sporting development behind the decline.
PredictionBubbles aggregates 514 open sports markets across Kalshi and Polymarket: 188 from Kalshi and 326 from Polymarket. Its embedded display features the 300 largest markets by traded volume, while the full board covers all 514.
The site separates activity from price movement. Its volume rankings measure total trading, while its movers list ranks absolute probability changes over the last 24 hours. Mensah’s $2.1M figure therefore describes trading activity, not the scale or direction of the latest repricing.
According to PredictionBubbles, both exchanges feed a pipeline refreshed every 15 minutes, although trading on the venues is continuous. The 21.0% reading is consequently a published snapshot rather than a guarantee of the price available afterward.
PredictionBubbles displays exchange prices and does not accept wagers, hold funds or offer accounts. It also cautions that related contracts across venues may have different wording and resolution rules; the supplied material includes no comparable Polymarket price for Mensah.
