Bracket families

12 clusters across 13 contracts.

These contracts were grouped by title similarity. The headline aggregate combines all clusters; verify the cluster you actually need before quoting a number.

Heads-up — heterogeneous clusters

The top two clusters share only 27% of their title tokens — “Will Tadej Pogacar win Stage” vs “Will Quinn Simmons win Stage 9 in the 2026 Tour de France”. The headline aggregate weights both, so the number on this page is meaningful only if the clusters resolve to the same question.

Analysis

This represents an estimated 9% chance that Filippo Ganna wins Stage 1 of the 2026 Tour de France, based on aggregated market data. The probability reflects that Ganna faces substantial competition from sprinters and time-trial specialists, with Tadej Pogacar and Kevin Vauquelin currently favored. Stage 1 format and weather conditions closer to July 2026 will clarify whether it suits Ganna's sprint capabilities or favors other riders. Ganna's current form, any pre-tour injuries or illness, and his team's tactical positioning will be critical determinants. The stage will resolve on approximately July 4, 2026, when results are finalized. Market pricing remains relatively illiquid, with minimal 24-hour trading volume on this specific contract, suggesting limited consensus about the likelihood.

  • Stage 1 terrain and finish type in the 2026 Tour route design — whether it's a sprint finish where Ganna's speed applies or a hilly/time-trial format favoring other specialists
  • Ganna's competitive fitness and health status in early July 2026, including any injuries or illness preventing peak performance
  • Team tactics and positioning — how Ganna's team deploys resources to support or protect him versus competitors' strategic choices
  • Historical head-to-head performance between Ganna and named competitors (Pogacar, Evenepoel, Vauquelin, Arensman) in similar stage formats
  • Market liquidity and contract volume are very low ($0 24h volume on Ganna's contract), indicating high uncertainty and limited analytical consensus

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
