FAQ

Which prediction market has the best odds?

It changes game by game. Across the 174 outcomes we can compare right now, Kalshi and Polymarket US differ by a median of 1 points after taker fees, and Kalshi is the cheaper place to buy 45% of the time. The board highlights the cheaper US venue for every outcome.

What does "after fees" mean?

Kalshi and Polymarket charge a taker fee of rate × contracts × price × (1 − price) when you buy at the ask: 0.07 on Kalshi, 0.0695 on Polymarket US and 0.05 on Polymarket sports markets. "After fees" adds that fee to the price, so you compare what one $1 contract really costs. Maker orders and volume rebates can cost less.

Why is Polymarket greyed out?

Polymarket’s international site doesn’t accept US users. We show its price for reference only. Polymarket US is the separate CFTC-regulated app for US customers.

Is there arbitrage between Kalshi and Polymarket?

Almost never after fees. A gap of a point or two is usually smaller than the two taker fees combined. Use the arbitrage calculator to check a specific pair of prices.
