Andrey Rublev wins priced at 1.0% on Kalshi, down 42.0 points, on $893K traded

The Kalshi contract on Andrey Rublev winning was priced at 1.0%, down 42.0 probability points, with $893K traded, in the snapshot accompanying the Oct 27, 2026 · 11:09 AM ET report. According to PredictionBubbles’ movers board, it was the largest downward move in the sports category.

The supplied material does not identify the competition covered by the contract or explain what triggered the decline. The sports ranking is separate from the board’s lead item, so it should not be read as identifying Rublev as the biggest mover across all categories.

How the move is measured

According to predictionbubbles.net, the board compares venue prices over 24 hours and refreshes every 15 minutes. Its supplied snapshot was read from the venues on 27 Oct 2026, 15:05 UTC, covering Polymarket and Kalshi.

The rankings measure changes in probability points, rather than relative percentages. Rublev’s 42.0-point decline therefore describes the change in the contract’s implied probability—not a 42.0% relative fall. Trading volume provides context but does not affect a market’s place in the ranking.

Scope and limits

PredictionBubbles says its ranking spans 2,011 markets that remain live for more than 14 days, excluding same-week fixtures to prevent short-lived settlement swings from dominating. Only open contracts with a valid 24-hour comparison qualify. The supplied table displayed the top 150 of 503 markets moving by at least one probability point.

The $893K traded figure adds context to Rublev’s repricing, but the supplied material does not establish the contract’s order-book depth or a news catalyst. The price move alone cannot explain why traders changed their assessment or establish the eventual result.

What it means for prediction markets

• A sharp change in pricing: The 1.0% price and 42.0-point decline show a substantial downward reassessment over the board’s 24-hour measurement window.
• A category-specific distinction: Rublev led downward sports moves within the board’s eligible universe, not necessarily all sports contracts or all markets.
• Important information remains missing: Without the competition, resolution terms or a documented catalyst, the snapshot supports analysis of the repricing—not a conclusion about its cause.
