PredictIt review (2026): the small, legal US prediction market
Published 2026-05-22 · Last reviewed 2026-05-22
TL;DR
- PredictIt operates under a CFTC no-action letter granted to Victoria University of Wellington.
- Strict limits: $850 invested per market, 5,000 traders per market.
- Best-in-class political coverage; weak everywhere else.
PredictIt is the dorm-room prediction market: tiny position caps, deep political coverage, and a regulatory cliffhanger that won't quit.
The headline verdict
PredictIt is a niche venue worth knowing about, not a primary trading platform. The $850-per-market cap means it can't be your main book. But for certain political markets — congressional control, presidential primaries, individual Senate races — PredictIt has been the canonical prediction-market venue for a decade.
What's good
- Legality. US-legal under a CFTC no-action letter; PredictIt accepts US users without geo-restriction.
- Political market depth. Long-running coverage of US elections, individual races, and policy outcomes — often listed before Kalshi catches up.
- Resolution track record. Years of clean, timely settlements on political contracts.
- USD funding. Standard ACH and debit-card funding.
What's bad
- $850 cap per market. Hard limit; you cannot scale beyond it.
- 10% profit fee + 5% withdrawal fee. The highest fee structure in the category.
- Web-only. No native mobile apps.
- Limited market types. Almost exclusively political. No sports, no crypto, no admissions.
- Regulatory uncertainty. The CFTC moved to revoke the no-action letter in 2022; PredictIt's continued operation is contingent on ongoing litigation.
Who should use PredictIt
Political junkies trading small. Researchers studying market-based forecasting. Anyone who wants exposure to a specific congressional race that hasn't been listed on Kalshi yet.
Who should not
Anyone trading real size. Anyone who needs low fees. Anyone whose interest is non-political markets.

Frequently asked questions
Is PredictIt legal in the US?
Yes — PredictIt operates under a long-standing CFTC no-action letter granted to Victoria University of Wellington for academic research. The CFTC moved to revoke it in 2022; ongoing court actions have kept PredictIt running.
What is PredictIt's position limit?
$850 of total investment per market and 5,000 unique traders per market. These caps are the trade-off for the no-action letter status.
What are PredictIt's fees?
10% on profits and 5% on withdrawals. By far the highest fees in the category — a deliberate constraint of the research-exemption model.
Is PredictIt better than Kalshi?
Only for niche political markets that Kalshi hasn't listed. For everything else — fees, scale, mobile app, market selection — Kalshi is better.
