Several factors can shift odds significantly before Stage 1 concludes. Weather forecasts—particularly wind, rain, or extreme heat—can favor certain rider types and trigger repricing. Announcements about injuries, mechanical issues, or team strategy changes influence trader sentiment on specific competitors. Pre-race media coverage and expert commentary often spark buying or selling waves as new analysis reaches the market. On race day itself, live footage and real-time developments during the stage create rapid price swings as traders react to breakaways, crashes, and positioning. Close finishes or photo-finish scenarios may also cause temporary volatility as the outcome becomes uncertain.
