About PredictIt
PredictIt occupies a strange regulatory niche that tells you everything about how prediction markets have been treated in the United States. Operated by Victoria University of Wellington (New Zealand), PredictIt was granted a CFTC no-action letter in 2014 -- not approval, not regulation, but a letter saying the CFTC would not take enforcement action against the platform as long as it operated within strict limits. Those limits: no more than 5,000 traders per market, no more than $850 invested per question per trader, and the platform must serve an academic research purpose. The academic angle is real -- researchers at universities including Stanford, Wharton, and MIT have published peer-reviewed papers using PredictIt data to study crowd forecasting accuracy. In August 2022, the CFTC revoked PredictIt\'s no-action letter and ordered the platform to wind down by February 2023. PredictIt sued, arguing the revocation was arbitrary and violated administrative procedure. A federal court issued an injunction allowing PredictIt to continue operating while the case played out. As of early 2026, PredictIt remains operational in a legal limbo -- allowed to exist by court order but without the regulatory blessing it once had. This uncertainty matters for users: the platform could be forced to close with relatively short notice if the court case resolves unfavorably. The $850 per-contract cap creates an unusual market dynamic. Because no single trader can risk more than $850 on a question, PredictIt markets are dominated by small-dollar participants rather than whales. Academic research suggests this cap actually improves prediction accuracy for moderate-probability events (30-70% range) because prices reflect a genuine crowd consensus rather than the risk appetite of a few large players. However, the cap reduces liquidity and creates persistent mispricings at the extremes -- contracts at $0.01-$0.05 and $0.95-$0.99 often do not move efficiently because the potential profit per contract is too small to justify the effort of trading. The 5,000-trader limit per market means popular events (presidential primaries, general elections) fill up quickly, locking out latecomers entirely.
Key Features
Political Market Specialization
PredictIt focuses almost exclusively on U.S. political events -- elections, legislation, Supreme Court decisions, and policy outcomes. This narrow focus means the community has deep political expertise. Traders include political operatives, campaign staff, journalists, and policy analysts who bring genuine insider knowledge (publicly available information, not illegal insider trading) to the market.
Academic Research Foundation
PredictIt is not a commercial venture -- it is a research platform operated by a university. The data generated by PredictIt has been used in over 100 academic papers studying the accuracy of prediction markets versus polls, the speed of information incorporation, and the behavioral economics of crowd forecasting. If you trade on PredictIt, you are contributing to published research.
$850 Position Limit
The \$850 maximum investment per question per trader is a regulatory constraint, not a feature. But it has an unexpected benefit: it prevents whale manipulation. No single trader can move a PredictIt market with capital alone. This makes PredictIt prices a purer signal of crowd belief, not capital concentration. Academic studies have shown PredictIt is better calibrated than Iowa Electronic Markets (another academic market) for this reason.
Real USD Trading
PredictIt trades in real U.S. dollars, not cryptocurrency or play money. You fund via credit card, debit card, or bank transfer. This means the results reflect genuine financial stakes, even if the stakes are capped. The academic literature is clear that real-money prediction markets outperform play-money markets on accuracy.
Continuous Trading Until Resolution
PredictIt markets remain open for trading until the event resolves, allowing prices to update continuously as new information emerges. During primary season, you can watch PredictIt prices react in real time to debate performances, poll releases, and endorsement announcements. This makes the platform a living dashboard of political probability.
How It Works
Create an Account
Sign up with email and verify your identity. PredictIt requires SSN for U.S. residents (for tax reporting and compliance with their CFTC no-action letter terms). International users can also participate with passport verification.
Deposit Funds
Fund your account via credit card, debit card, or bank transfer. Minimum deposit is $5. There is no deposit fee, but the 5% withdrawal fee means you should plan to keep funds on platform until you are done trading, rather than depositing and withdrawing frequently.
Browse Political Markets
Markets are organized by category: presidential elections, Congressional races, policy outcomes, Supreme Court decisions, and more. Each market shows the current Yes/No price, number of traders, and resolution criteria. Check whether a market has hit its 5,000-trader cap before planning a trade.
Trade and Track
Buy Yes or No shares at the current market price or set a limit order. Your maximum investment per question is $850. Track your positions and sell at any time before resolution. If your prediction is correct, each share pays $1.

Review Summary
Notable Case Studies
2024 Presidential Primary Trading
A political science graduate student used PredictIt to trade Republican primary markets, buying "No" on candidates she assessed as media-inflated but electorally weak. She cross-referenced PredictIt prices against her own model built on FEC fundraising data, state-level polling, and endorsement patterns.
Policy Outcome Hedging
A renewable energy company executive bought "Yes" contracts on "Will Congress pass an EV tax credit extension?" on PredictIt at \$0.45. If the credit was extended, his company's stock would benefit and the PredictIt position was redundant. If the credit was not extended, the \$850 PredictIt payout would partially offset the business impact.

Actually used for academic research
I used PredictIt data for my thesis on crowd forecasting. The fact that this is a university-operated platform with published research behind it gives it credibility that Polymarket and Kalshi don't have. Yes it's slow, yes the fees are high, but the data quality is peer-reviewed.
Still the best for down-ballot races
Kalshi does the big markets better but PredictIt has Senate and House races that nobody else lists. If you care about whether the Montana Senate seat flips, this is where you go. Niche but valuable.
Used it for the election
Made some money on the presidential market but between fees and the 850 cap it wasn't life changing. Fun though. Interface looks like it was built in 2014 because it was.
The data nerd's choice
I'm a political data analyst and PredictIt is part of my daily workflow. The prices tell me what politically engaged people with money on the line actually think, not what polls say. It's a different signal and it's valuable. Yes the fees suck. I pay them anyway.
The fees though
10% of profits PLUS 5% on withdrawal. Do the math. Win a trade that makes $100 profit, they take $10. Withdraw your $190 and they take another $9.50. You keep $80.50 on what should have been a $100 win. That's brutal. Kalshi and Polymarket don't do this.
TRADER LIMIT IS SO ANNOYING
Wanted to trade the special election market and it was already capped at 5000 traders. So I just... can't? What kind of market locks you out because too many people want to participate? That defeats the entire purpose. And there's no waitlist or anything. You just can't trade. Ridiculous.
The OG political prediction market
Been on PredictIt since 2016. The community is amazing. You're trading against political consultants, former Hill staffers, and campaign nerds. The conversations in the comments are worth more than the trades sometimes.
good for politics
If all you want to trade is politics it's fine. The $850 limit is annoying though.
MIGHT SHUT DOWN ANY DAY AND THEY ACT LIKE EVERYTHING IS NORMAL
They are literally being sued by the CFTC and could be forced to close and they barely acknowledge it on the site. I have money in open markets that won't resolve for months. What happens to my money if they shut down before the market resolves?? Nobody will give me a straight answer. I'm not depositing another dime until the court case is settled.
it is what it is
It works. Fees are high. Interface is old. But it's been around for 10 years and the political markets are deep. Use it for what it is.
