Frequently Asked Questions
Is Kalshi a legit Polymarket alternative?
Yes — Kalshi is CFTC-regulated and operates legally in all US states. It offers fewer markets than Polymarket but with clearer regulatory protection.
What's the difference between Polymarket and Limitless?
Polymarket is the largest crypto prediction market with the deepest liquidity. Limitless runs on Base with continuous (perpetual) markets and lower fees, but smaller volume.
Can I use one account to trade Polymarket and Kalshi?
Yes, with PredictEngine. One signup, one deposit, and your funds are allocated across Polymarket, Kalshi, and Limitless. Cross-venue arb runs automatically.
Why use multiple prediction markets instead of just Polymarket?
Different venues quote the same event at different prices — that's where arbitrage edges come from. Plus regulatory diversification: Kalshi remains accessible if Polymarket has US regulatory issues.
