Check settlement rules before comparing contracts. Matched outcomes may settle differently. These are stored prices; record update times do not certify live quotes. Differences exclude fees and available size.

Known rule differences between venues

Kalshi settles on CF Benchmarks real-time indices (e.g. BRTI); Polymarket on Binance USDT-pair 1-minute candle highs/lows. A brief wick on one source may not appear on the other.
Windows differ: Polymarket counts from market creation; Kalshi rungs count from each rung's own start date (e.g. Feb 5, 2026 for some 2026 lows).
Kalshi rungs are strict ('Above $99,999.99', 'Below $55,000'); Polymarket rungs are inclusive. They differ only at exactly the level.

A shared identity alone does not make a price difference executable.
