Analysis

The 9% probability indicates markets assess Nathan Florence has roughly a 1-in-11 chance of winning the Wave of the Winter award in 2026. The low odds likely reflect competitive depth in professional surfing, where multiple elite athletes compete across variable ocean conditions throughout the season. Factors supporting higher odds would include consistent high placements in major competitions or favorable swell patterns at key events. The main catalyst determining this probability will be results from major surfing competitions as they occur throughout the winter season, with year-end award voting providing final resolution.

  • Nathan Florence's historical placement rates in Wave of the Winter voting compared to current year competition field
  • Volume and consistency of high-scoring waves Florence produces relative to competing professional surfers
  • Ocean swell patterns and scheduling of major surfing events during the winter period affecting opportunity for standout performances
  • Voting methodology for Wave of the Winter award and any changes to judge panels or criteria for 2026
  • Results from significant competitions held prior to and during the winter season that influence year-end voting

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.
