Analysis

This 18% probability estimates Lorenzo Musetti's chances of winning the ATP Rome tournament. The market reflects his status as a solid but not elite competitor on clay, where he has shown capability but inconsistent results against top-ranked opponents. The key factors driving this level are Musetti's historical performance at Rome, his current ranking and form relative to other contenders, and the strength of the competing field. The tournament itself will serve as the ultimate data point, with results beginning in the coming weeks and culminating in a champion. Movements in this probability would reflect injury announcements, recent warm-up tournament outcomes, and any shifts in the broader ATP rankings that indicate momentum changes among the field.

  • Musetti's historical win-loss record and seeding at Rome over the past three years relative to other Italian players and clay-court specialists
  • Current ATP ranking and recent match results in clay-court events leading into Rome
  • Injury status or withdrawal announcements by top-seeded players, which would increase draw accessibility for lower-seeded competitors
  • Head-to-head records and performance data of Musetti against the top five favorites currently priced in the market
  • The tournament draw configuration once announced, including Musetti's projected path to the final based on seeding

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.
