Analysis

The market is pricing a 95% probability that Honey Deuces—a beverage sold at the US Open tennis tournament—will exceed 650,000 units sold in 2026. This reflects strong confidence in baseline demand, likely driven by the drink's established presence at the tournament and typical attendance levels. The probability drops significantly at higher thresholds: 77% for 750,000 units and 29% for 900,000 units, suggesting traders see limited upside beyond normal sales patterns. Resolution depends on the actual sales figures reported after the tournament concludes in September 2026, making final ticket sales, tournament weather, and vendor performance key determinants of outcome.

  • US Open 2026 total attendance figures relative to historical averages will directly affect baseline concession sales volumes
  • Honey Deuce pricing and per-capita purchasing rates compared to 2024-2025 tournament data will determine whether sales reach stated thresholds
  • Tournament duration and scheduling (weather delays, extended matches) could increase or decrease total venue hours and sales opportunities
  • Competitive beverage options and vendor inventory allocation may shift consumer preferences toward or away from Honey Deuces
  • Official sales reporting from USTA or venue operators must be disclosed to definitively resolve the contract by the stated threshold amounts

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.
