Which platform should I start with?

If you're in the US, Kalshi is the most straightforward — CFTC-regulated, standard bank deposits, no crypto wallet needed.

Which has the lowest fees?

Fee structures change and vary by trade type. Check each platform's current fee schedule. Keep in mind that low fees don't help if the platform has thin liquidity — slippage can cost more than the fee savings.

Are these platforms safe?

Kalshi and Polymarket US both have CFTC regulation. The international version of Polymarket runs on crypto, which carries smart contract and custody risk on top of normal trading risk. Research each platform before depositing.

Should I use more than one?

If you're serious about it, yes. Different platforms price the same events differently, and having accounts on 2–3 lets you take the best number every time. That's also how arbitrage works.
