PredictIt Review 2026: Fees, Markets & Features

Trading on PredictIt

PredictIt is the longest-running prediction market in the United States, originally launched in 2014 under a CFTC no-action letter as an academic research project operated by Victoria University of Wellington. After a protracted legal battle - the CFTC attempted to revoke the no-action letter in 2022 - PredictIt won a court challenge in July 2025 and emerged as a fully CFTC-registered exchange. The platform survived where others did not, and its political-only focus has created a dedicated community of political traders who have been refining models on this platform for over a decade.

Trading is straightforward: buy Yes or No shares in political markets, priced from $0.01 to $0.99. Position limits, once capped at $850 per contract, have been expanded to $3,500 following the regulatory resolution. Markets cover elections, policy outcomes, and political appointments.

Fee Structure Deep Dive

PredictIt's fee structure is the most punitive in the industry. The platform charges 10% on gross profits per market plus a 5% fee on all withdrawals.

Fee Worked Examples

At a $0.20 contract: you buy 100 shares at $0.20 ($20 invested). If the event resolves Yes, you receive $100. Gross profit: $80. PredictIt takes 10% = $8. Net after profit fee: $72. When you withdraw the $92 balance, the 5% withdrawal fee takes $4.60. Actual take-home profit: $67.40 on $20 risked. Effective fee rate on gross profit: 15.8%. Run these numbers through our fee calculator to compare against other platforms.

At a $0.50 contract: 100 shares cost $50. Resolution at $1.00 yields $50 gross profit. Profit fee: $5. Withdrawal fee on $95: $4.75. Take-home profit: $40.25 on $50 risked. Effective rate: 19.5% of gross profit.

At a $0.80 contract: 100 shares cost $80. Resolution at $1.00 yields $20 gross profit. Profit fee: $2. Withdrawal fee on $98: $4.90. Take-home profit: $13.10 on $80 risked. Effective rate: 34.5% of gross profit. High-probability contracts are where PredictIt's fees become most destructive - the withdrawal fee alone ($4.90) exceeds the profit fee ($2) when the gross margin is thin.

Walk through a portfolio-level example: you invest $1,000 across 10 markets, earn gross profits of $200, and take losses of $50 in others. PredictIt takes 10% of the $200 in winning markets - $20 - regardless of your losses elsewhere. Your net P&L is +$150, minus $20 in profit fees, leaving $130. When you withdraw your $1,130 balance, the 5% withdrawal fee takes another $56.50. Your actual take-home on a $150 net profit is $73.50 - a 51% effective fee rate.

The fees do not net across markets. A $100 gain in one market and a $100 loss in another results in $10 in fees on a net-zero trading outcome. This is fundamentally different from platforms like Polymarket, where the 2% fee applies only to net winnings. Use our EV calculator to model how PredictIt's fee structure affects your expected value across a portfolio of positions.

Market Coverage

PredictIt is politics-only: presidential elections, congressional races, gubernatorial contests, Supreme Court nominations, cabinet appointments, and policy outcomes like government shutdowns or legislation passage. There are no economics, sports, entertainment, or climate contracts.

Within that niche, PredictIt offers granularity that other platforms sometimes lack. Individual House races, state-level primaries, and obscure appointment markets appear on PredictIt before they surface on Kalshi or Polymarket. The platform's community of political specialists creates demand for deep-cut political contracts that a broader platform might not list.

The trade-off is obvious: if you want to trade anything outside US politics, PredictIt is not the platform. But for political specialists who want the deepest menu of political event contracts with the longest historical dataset, PredictIt remains the reference standard.

Tax Treatment

PredictIt does not issue 1099 forms automatically in all cases, and the platform's tax reporting has historically been less streamlined than brokerage-integrated platforms like ForecastEx. Traders are responsible for tracking their own gains and losses across individual contracts.

The 10% profit fee is deducted before your payout, but whether that fee is deductible as a trading expense depends on how your event contract activity is classified for tax purposes. The 5% withdrawal fee adds another layer of complexity. Maintain detailed records of every trade: purchase price, sale or settlement price, profit fees deducted, and withdrawal fees paid. A spreadsheet or portfolio tracker is not optional here - it is a necessity for tax compliance.

PredictIt has historically provided year-end transaction summaries, but the format and completeness have varied. Do not rely solely on PredictIt's records for tax filing.

Onboarding and Funding

PredictIt's signup process is straightforward: email registration, identity verification, and agreement to the platform's terms. Verification typically takes minutes to a few hours. Time from signup to first trade is generally under one day, faster than ForecastEx but comparable to Kalshi.

Funding options include credit cards, debit cards, and bank transfers (ACH). Credit card deposits are notable - most other prediction market platforms do not accept credit cards. The $3,500 per-contract position limit means you do not need a large bankroll to access every available market, but it also constrains sizing for traders who want to deploy more capital into high-conviction positions.

Withdrawals are processed via check or ACH, and the 5% withdrawal fee applies to the entire withdrawal amount (not just profits). This creates an incentive to minimize withdrawal frequency and keep capital on the platform - a structural advantage for PredictIt and a cost for traders who prefer to manage bankroll across multiple platforms.

Who PredictIt Is Best For

Political Specialists with Large Edges

PredictIt serves traders who have genuine informational edges large enough to overcome the fee drag. If your model consistently identifies $0.10+ mispricings in political markets, PredictIt can still be profitable despite the fees. Use our breakeven calculator to determine exactly how large your edge needs to be. If your edges are thinner than $0.10, the math does not work - consider the same political markets on Kalshi or Polymarket where you keep more of what you earn.

Political Junkies and Community Participants

PredictIt's decade-plus history has produced a community of political traders with deep institutional knowledge. Forum discussions, historical calibration data, and established market conventions create an ecosystem that newer platforms have not replicated. If you value the community and historical context alongside your trading, PredictIt offers something unique.

Researchers and Data Analysts

Over 10 years of political market data, including prices, volumes, and resolution outcomes, makes PredictIt a research asset. Academic papers, forecasting models, and political analysis have been built on PredictIt data. If your primary goal is research rather than profit maximization, the fee structure matters less.

The Comeback Tax

PredictIt's survival is remarkable, and the community knowledge embedded in the platform - years of political trading history, calibrated user bases, and established market conventions - has real value. But the economics are brutal. A trader who is profitable on Kalshi at a 3% effective fee rate would need roughly 3-4 times the edge to achieve the same return on PredictIt after fees.

Before committing capital, calculate your expected edge per market and subtract the 10% profit fee plus the 5% withdrawal fee from your projected returns. If the number is still positive with a meaningful margin of safety, PredictIt's political market depth may be worth the cost. If not, the same political markets on Kalshi or Polymarket will let you keep more of what you earn.
