Kalshi — deeper editorial note
Kalshi is the cleaner default US research path in our rankings: regulated event-contract framing, mandatory KYC, and a wider listed-contract mix than a politics-only specialist.

PredictIt — deeper editorial note
PredictIt is best treated as a politics overlay, not a full replacement for Kalshi. Use it to stress-test election market wording, limits and settlement expectations.

Portfolio thinking for US users
Many US researchers do not need to “pick a forever platform.” Kalshi covers a wider regulated event-contract set; PredictIt adds politics depth. Using both for research is normal; funding both is optional.
What we would not do
We would not recommend PredictIt as a general replacement for Kalshi across economy/weather contracts, and we would not treat either venue as a crypto on-ramp.
How GammaPredict would decide
We do not push a single winner. Start from region + KYC preference + market category, then compare liquidity on the specific event you care about. Platform-level scores can hide thin markets.
Next steps: open the side-by-side compare tool, read both profiles, and confirm eligibility on the platform itself.
FAQ
Kalshi or PredictIt for US beginners?
Start with Kalshi for a broader regulated event-contract path, then open PredictIt if politics depth is the job.
Do both require KYC?
Yes — both are account/KYC oriented rather than wallet-first.
What if I want crypto markets?
Neither is the crypto story. Compare Polymarket only if eligible, or see crypto prediction markets.
Is this legal advice?
No. GammaPredict is editorial only. Confirm products, states and tax treatment yourself.
