Analysis

This probability represents the likelihood that Mirra Andreeva will defeat Maja Chwalinska by winning the first two sets without dropping a set. The 25% estimate suggests markets view this as a meaningful possibility but not the most likely outcome—traders assign roughly 57% to an Andreeva 2-0 victory based on contract pricing, with alternative scenarios like Chwalinska winning 2-1 (14%) or Andreeva winning 2-1 (21%) splitting the remaining probability. The probability reflects relative playing strength, recent form, and head-to-head history between the two players. A straight-sets win requires dominant performance rather than a competitive three-set match, making this outcome more specific than simply picking a winner. The match itself will resolve all uncertainty once played.

  • Recent ATP/WTA rankings and seeding differential between Andreeva and Chwalinska establish baseline competitive gaps
  • Head-to-head record and performance patterns in previous meetings, if any, directly indicate stylistic matchups
  • Surface type and venue conditions of the scheduled match (hard court, clay, grass) favor different playing styles and influence set-win probabilities
  • Recent form and injury status of both players in the weeks leading up to the match affect confidence in dominant performance
  • Contractual pricing shows markets assign 57% to the 2-0 outcome specifically, implying 43% probability that the match goes to at least three sets regardless of winner

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.
