PredictIt Review 2026: Is the Academic Prediction Market Still Worth It?
PredictIt is the original US political prediction market. Operated as a research project by Victoria University of Wellington, it lives under a CFTC no-action letter with tight position limits. For small-scale, US political trading it is still useful, but Kalshi has eclipsed it on liquidity, fees, and market breadth.

The 30-second verdict. PredictIt is a legitimate but aging US political prediction market. It has lived under legal uncertainty for years (the CFTC tried to revoke its no-action letter in 2022, but federal courts granted a preliminary injunction that let it keep operating). The $850 per-market position cap, 10% fee stack, and narrow political-only focus make it hard to recommend for serious traders in 2026. Use it for small-dollar political bets or research; use Kalshi for everything else.
Pros and cons

- Longest track record of any US-legal prediction market (operating since 2014)

Where it falls short
- Tight $850 maximum position per market caps upside for serious traders

- Politics-only (no sports, economics, weather, or crypto markets)
- Ongoing legal uncertainty around its CFTC no-action status
- No mobile app; web-only interface
- No sign-up bonus or promotions

What is PredictIt?
PredictIt is a real-money political prediction market operated by Victoria University of Wellington in partnership with US academic researchers. It launched in 2014 under a CFTC no-action letter that permits real-money trading on political events for research purposes, subject to strict limits.
Unlike Kalshi, PredictIt is not a fully regulated exchange. Its legal status has been contested: the CFTC moved to revoke the no-action letter in 2022, but federal courts granted PredictIt a preliminary injunction that has kept it operating. As of 2026, trading continues and the litigation remains unresolved.
Markets and coverage
PredictIt lists roughly 30 to 80 active markets at any given time, all focused on US and occasionally international politics:
- Presidential, Senate, House, and gubernatorial elections
- Presidential approval ratings and policy milestones
- Primary nomination odds and debate participation
- Supreme Court vacancies and confirmations
- Occasional international political events (UK, Canadian elections)
Flagship markets (presidential election, party control) see respectable volume but nothing close to Kalshi or Polymarket. Most markets trade in the tens of thousands of dollars per day, not millions.
Fees and costs
PredictIt’s fee structure is the harshest of any platform in our rankings:
- 10% profit fee on net winnings per market, charged at market resolution
- 5% withdrawal fee on all money taken off the platform
- Combined effective fee on a winning position often exceeds 15%
There are no deposit fees, no monthly fees, and no spread markups beyond the natural bid-ask. Still, the profit-fee plus withdrawal-fee combination is a serious drag on returns, especially for frequent traders.
Legal status and safety
PredictIt operates under a 2014 CFTC no-action letter. In 2022, the CFTC attempted to revoke that letter, which would have shut the platform down. PredictIt (with academic partners) sued in federal court, and the Fifth Circuit granted a preliminary injunction that has allowed operations to continue while the underlying case works through the courts.
Funds on PredictIt are held in pooled accounts, not segregated like Kalshi. If the platform lost its court case and had to wind down, there would likely be an orderly return of user balances, but there is no formal regulatory guarantee.
For US traders who want regulatory protection, Kalshi is the safer choice. For non-US political trading, Polymarket offers deeper markets without US access.
PredictIt vs Kalshi: which should you use?
For US political markets in 2026, Kalshi wins on almost every metric:
- Position limits: Kalshi has no $850 cap. You can size positions freely.
- Fees: Kalshi’s 1 to 3% trading fee is far lower than PredictIt’s 10% profit fee plus 5% withdrawal fee.
- Market breadth: Kalshi covers politics, economics, sports, weather, and more. PredictIt is politics-only.
- Regulatory protection: Kalshi is a CFTC DCM with segregated funds. PredictIt relies on a contested no-action letter.
- Liquidity: Kalshi’s flagship markets trade 10 to 50x the volume of PredictIt equivalents.
The one place PredictIt still holds value: its historical dataset is the deepest of any real-money US political market, which matters for researchers and quantitative traders with back-testing needs.

Visit PredictItFrequently asked questions
Is PredictIt still legal in the US?
Yes, as of 2026. PredictIt operates under a CFTC no-action letter. The CFTC attempted to revoke that letter in 2022, but federal courts granted a preliminary injunction that has kept the platform operating while litigation continues.
Why is the $850 position limit so low?
The $850 cap is a condition of PredictIt’s CFTC no-action letter, which permits real-money trading specifically as an academic research tool. Lifting the cap would require full CFTC exchange designation (like Kalshi has).
Are PredictIt fees really 15%?
It depends on your trading pattern. You pay 10% on net profits per market at resolution, plus 5% when you withdraw. On a pure winner you net about 85%, but high churn and many small wins can compound the friction.
Does PredictIt offer non-political markets?
No. PredictIt is politics-only. For economics, sports, weather, or crypto markets, use Kalshi or Polymarket.
Can I use PredictIt outside the US?
No. PredictIt is open to US residents only. International users should use Polymarket.
What happens to my money if PredictIt loses its court case?
The academic operator would have to wind down orderly. Historically PredictIt has indicated it would return user balances. Still, there is no formal regulatory backstop.
