How did you compare Polymarket US and Kalshi prices?

For each team we took the best ask (the price to buy one contract) on each venue in the same minute and added that venue's published taker fee at that price. Polymarket US prices come from PredictionMarketsPicks' Polymarket US snapshot table, checked against Polymarket US's public feed; Kalshi prices come from Kalshi's public market data. A gap under half a cent counts as the same price. Only games that had not kicked off are included.

Why Polymarket US often prints half a cent lower

Two things drive most of the gaps on this page:

Tick size. In this read, Polymarket US quoted college football game markets in half-cent steps (20.5¢, 55.5¢), while Kalshi's game markets quoted in whole cents. When both books sit at the same spot, Polymarket US's ask can land half a cent inside Kalshi's.
Fees. Both venues charge a taker fee that scales with price × (1 − price), so it peaks at 50¢ and shrinks toward 0¢ and 100¢. Polymarket US's published rate is slightly lower than Kalshi's. See Polymarket US fees and our Kalshi fee calculator for the exact schedules.

Kalshi was cheaper on 1 of the 62 sides in this read. The venue that's cheaper on one team isn't always the cheaper one on the other team in the same game, because each venue's book is its own.

How we priced it

Polymarket US: the latest reading in PredictionMarketsPicks' Polymarket US snapshot table for each game-winner market, checked against Polymarket US's public feed at 2:33 p.m. ET. Games where the two disagreed at that minute (1) are left out.
Kalshi: Kalshi's public market data for its college football game-winner markets, read at 2:33 p.m. ET.
All-in price: best ask plus that venue's taker fee at that price, per contract. Kalshi rounds its fee up to the next cent per order, so a one-contract order pays slightly more than shown; at 100 contracts the difference disappears.
Same price: a gap under half a cent (0.50¢). All-in prices show two decimals so you can see why a pair counts as the same.
Only games that had not kicked off at 2:33 p.m. ET, and only books with both a bid and an ask no more than 15¢ apart.
