Alex Rybakov wins priced at 1.0% on Kalshi, down 55.0 points, on $1.2M traded

The Kalshi contract on Alex Rybakov winning stood at a market-implied probability of 1.0%, down 55.0 percentage points over 24 hours, with $1.2M traded, according to PredictionBubbles. Its Oct. 29 snapshot identified the contract as the largest downward mover on its sports board.

A sharp move, with limited event detail

The supplied summary places the board’s crawl at Oct. 29, 05:11 UTC, with 527 open markets and $769.0M in traded volume. The story’s publication timestamp is Oct. 29, 2026 · 1:09 AM ET.

The material does not identify Rybakov’s opponent, the event, the contract’s resolution deadline or the reason for the decline. The price move therefore cannot be tied to a particular sporting development from the information provided.

Board totals reflect different snapshots

The supplied PredictionBubbles page shows a different count: 545 sports markets, comprising 219 on Kalshi and 326 on Polymarket. Those figures should be kept separate from the summary’s 527-market snapshot rather than treated as a single synchronized reading. PredictionBubbles says its data refreshes every 15 minutes.

The site ranks movers by the absolute change in market-implied probability over 24 hours, while its volume rankings measure total trading. Its supplied page names “Will Shakhtar Donetsk win the 2026-27 UEFA Champions League Championship?” as the most-traded sports contract at the last refresh, with $36.9M traded on Polymarket.

PredictionBubbles aggregates exchange prices rather than setting them or accepting wagers. It also cautions that related contracts across Kalshi and Polymarket can differ in wording and resolution rules, limiting direct comparisons.

What it means for prediction markets

• The decline is in percentage points: Rybakov’s 55.0-point fall is a change in implied probability, not a 55.0% relative decline.
• Volume and movement describe different things: The $1.2M figure is total traded volume; the supplied material does not establish how much traded during the decline.
• A low price is not a resolution: The 1.0% reading reflects traders’ pricing, while the material provides neither a confirmed sporting outcome nor the contract’s settlement terms.
• Snapshot timing matters: The differing board totals and 15-minute refresh cycle mean the figures should be read with their respective timestamps and context.
