If this is your first time trading on Kalshi, keep these differences in mind which differentiate Kalshi from a traditional sportsbook:
- Funding: Kalshi takes dollars from your bank account or debit card. Polymarket runs on USDC.
- Oversight: The CFTC regulates Kalshi as a federal exchange, which allows users in states like California and Texas to join in on the fun.
- Depth: Polymarket is especially useful for trading on season long markets. Kalshi posts thick single game and player boards for every MLB slate while still offering futures contracts
