Where Polymarket and Kalshi price the same outcome differently, right now.
What you're looking at. Each row is a single real-world outcome that both venues quote, matched at the specific-question level (not by broad title), where their YES prices currently disagree. The bar shows each venue's price on a 0–100% axis; the shaded span is the gap.
How gaps this size have behaved (backtested: past behaviour, not a prediction or advice).
