Analysis

This 68% probability reflects market expectations that Jannik Sinner will win the 2026 Men's Singles title at Roland Garros, scheduled for late May. Sinner's ranking, recent performance, and clay-court consistency have established him as the clear favorite, though the market assigns roughly 32% combined probability to other contenders. The price is primarily driven by his status as world number one and track record on European clay surfaces. Upcoming tournaments in spring 2026, injury reports, and performance at earlier clay events this season will likely adjust the probability meaningfully. The contract shows minimal trading volume ($3 in 24 hours), suggesting limited recent conviction shifts despite the high odds. Historically, favorites in Grand Slams face unpredictable challenges from Form variance, surface conditions, and draws that can alter outcomes substantially.

  • Sinner's current ATP ranking and clay-court win rate relative to other top-10 competitors in May 2026
  • Trading volume and price movement across competing contracts (Musetti at 3¢, Zverev at 12¢) indicating whether the 68¢ reflects consensus or concentrated bets
  • Results from warm-up clay tournaments in April-May 2026 immediately preceding Roland Garros
  • Injury or fitness status updates for Sinner and top 5 rivals in the 60 days before the tournament
  • Head-to-head records and recent match outcomes between Sinner and the 12¢-priced contenders

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.
