| Kalshi | Polymarket | |
|---|---|---|
| Regulation | CFTC-regulated US exchange | Onchain, USDC settlement |
| Account | KYC, US bank funding | Crypto wallet |
| Cost | Per-contract trading fee | Maker/taker plus gas |

| Best for | Weekly game-by-game trading | Season-long and CFP futures |
Which venue for which trade
Weekly game trading where you want a clean US-regulated rail and predictable settlement belongs on Kalshi. Conference-title, playoff-field and Heisman futures usually price better on Polymarket, where long-dated capital is more patient and the crowd is larger.
Cross-venue spreads on the same game are common in the first hour after a starting quarterback is ruled out. That is the single most repeatable college football edge on the board, and it usually closes within a few hours.
Quick answers
Is Kalshi legal in the US?
Kalshi operates as a CFTC-regulated designated contract market, which is why it can offer event contracts to US residents directly.
Which has lower total cost?
Kalshi's per-contract fee is predictable; Polymarket can be cheaper on large size but adds gas and stablecoin conversion friction.
Can I hedge across both?
Yes. Buying the same outcome cheaper on one venue and selling it richer on the other is the standard cross-venue arb, limited mainly by depth and capital lockup.
