Polymarket delay is measured from the first onchain outcome proposal to resolution (UMA challenge window, minimum 2h by protocol). Kalshi delay is settlement_ts - close_time (exact from API), where close_time is the scheduled market close, not the real-world event end. Kalshi auto-generated parlay markets (Exotics) are excluded. Both anchors are lower bounds on total user wait from the real-world event ending.

How this pair was selected

Auto-generated pairs require: both providers in the same benchmark for seven consecutive days, at least 1000 samples per provider, observable third-party search demand, and a public /products/[slug] page on OCB. Editorially curated pairs (like this one) may publish early when search demand is high and data is accruing — panels with fewer than 100 samples are shown as provisional. The full pair ledger is versioned in the public repo.

Live data refreshes via ISR within 60 seconds of a new run. Sources are the same Prometheus queries surfaced on the parent benchmark pages.
