Analysis
This contract measures whether Costco's total monthly foot traffic in August 2026 will exceed 93 million visits. The 51% probability indicates traders slightly favor a result above this threshold, though the outcome remains uncertain. Costco's traffic typically reflects consumer spending patterns, economic confidence, and seasonal retail activity. August represents a back-to-school and late-summer shopping period, which historically drives warehouse traffic. The resolution will depend on actual foot-traffic data Costco reports, likely in late August or early September when the company releases monthly operational metrics. Economic conditions, gas prices, and employment levels heading into August will influence consumer behavior. The tight clustering of contracts around 93-96 million visits suggests traders view the likely outcome in this narrow band, with the 51%-49% split indicating genuine disagreement about whether August traffic stays below or above the 93 million threshold.

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.
