PredictIt Platform Guide 2026
The original U.S. prediction market, running under a CFTC no-action letter since 2014. Deep political markets, loyal community, and a fee structure that punishes active traders.

Our Take
PredictIt is the original U.S. prediction market — founded in 2014 and still operating under a CFTC no-action letter granted for academic research. The platform has deep political market history and a loyal community, but its dual-fee structure (10% on profits + 5% on withdrawals) makes it expensive compared to modern CFTC-licensed competitors. Best for political researchers and casual traders who prefer PredictIt's format. Not recommended for high-volume traders where fees compound significantly.
Key Strengths
Deep Political Markets
The longest-running U.S. political prediction market with a dedicated community and years of historical data.
Accessible Entry Point
$10 minimum deposit and $3,500 position cap makes it low-barrier for casual traders.
CFTC Oversight
Operates under a CFTC no-action letter. While not a full DCM, it's been under CFTC regulatory oversight since 2014.
Research & API Access
Historical data is publicly available and well-documented. API access enables academic and quantitative research workflows.
Established Community
Active trader community with strong political market focus and long institutional memory around U.S. elections.
Familiar Interface
Clean, straightforward interface that political traders have used for years. Well-documented market rules.
Key Considerations
Expensive Dual-Fee Structure
10% on profits + 5% on withdrawals — significantly higher than modern CFTC-licensed platforms. At scale, these fees substantially erode returns. In plain English: PredictIt takes a dime out of every dollar you earn, then takes another nickel from every dollar you withdraw. On a $100 profit, you'd keep about $80.50 after both fees.
Not a Licensed DCM
PredictIt operates under a legacy no-action letter, NOT as a modern CFTC Designated Contract Market. Less regulatory protection than Kalshi.
Custodial Funds
Customer funds are held custodially, not in segregated bank accounts like DCM-licensed platforms. Less protection if the platform faces financial difficulties.
Limited Market Categories
Primarily focused on U.S. politics and policy. No weather, crypto, or broad economics markets that competitors offer.
Low Liquidity Outside Major Events
Order books thin quickly outside presidential elections and major Senate races. Niche markets can be difficult to exit.
Limited Regulatory Status
PredictIt operates under an updated CFTC no-action letter (July 2025), governed by the Prediction Market Research Consortium. It is not a licensed DCM — less regulatory protection than Kalshi or Polymarket US.

What Is PredictIt?
PredictIt is the original U.S. prediction market, launched in 2014 as a research project by Victoria University of Wellington (original 2014–2025 partner; governance transferred to Prediction Market Research Consortium / PMRC per CFTC Letter 25-20, July 2025). It operates under a CFTC no-action letter that allows binary event contracts as an academic research tool — not as a fully licensed Designated Contract Market.
Each contract trades between $0.01 and $0.99, representing the market's implied probability of an outcome. If you buy a "Yes" contract at $0.65, you pay 65 cents for a contract that pays $1.00 if the event happens. Your maximum loss is capped at what you paid — but PredictIt takes 10% of your profits when you win and 5% of your balance when you withdraw.
In plain English: PredictIt takes a dime out of every dollar you earn, then takes another nickel from every dollar you withdraw. On a $100 profit, you'd keep about $80.50 after both fees.
PredictIt's parent company, Aristotle, separately pursued full CFTC licensure. In September 2025, Aristotle Exchange DCM, Inc. and Aristotle Exchange DCO, Inc. received full CFTC DCM and DCO designation. On March 9, 2026, Aristotle sold those licensed exchange entities to Underdog. PredictIt itself was not part of that sale and continues operating under its original no-action letter.
Regulatory Note
PredictIt operates under a CFTC no-action letter, NOT as a licensed DCM/DCO. Aristotle Exchange's DCM + DCO (approved Sept 5, 2025) were sold to Underdog on March 9, 2026; Aristotle retained PredictIt which continues under its no-action framework.
Market Categories
PredictIt's market selection is heavily weighted toward U.S. politics and policy. Unlike Kalshi or Polymarket, PredictIt does not offer weather, crypto price, or broad financial markets. If political trading is your primary interest, PredictIt's depth is unmatched in the U.S. market.

Fees
PredictIt's fee structure is its most significant competitive disadvantage. Unlike modern CFTC-licensed platforms, PredictIt charges fees on both profits and withdrawals, which compounds over time for active traders.
In plain English: PredictIt takes a dime out of every dollar you earn, then takes another nickel from every dollar you withdraw. On a $100 profit, you'd keep about $80.50 after both fees.
Profit Fee
Charged on net winnings when a market resolves in your favor
Withdrawal Fee
Charged on the amount you withdraw from your account
Position Cap
Maximum per-contract position (raised in 2025 revised agreement)
The Double Fee Trap
On a $100 profit: PredictIt takes $10 (profit fee). Remaining balance = $190. Then 5% withdrawal fee on $190 = $9.50. You net $80.50 from a $100 win. By contrast, Kalshi's formula-based fee on a comparable trade is typically under $2. The gap widens significantly at scale.
Hidden Cost: The Spread
Beyond the stated fee, bid-ask spreads on thin PredictIt books can be wide outside major events. The combination of spread cost + 10% profit + 5% withdrawal makes PredictIt expensive for all but the most accurate traders.
Deposits & Withdrawals
PredictIt supports credit/debit card and PayNearMe funding. The minimum deposit is $10 and the maximum position per contract is $3,500. All withdrawals incur the 5% fee.
| Method | Timeframe | Fee |
|---|---|---|
| Credit/debit card | Varies by card | None for deposits; 5% on withdrawals |
| PayNearMe | Varies | PayNearMe network fees may apply |
| Compliance review | Case-by-case | N/A |
Position Cap Reality Check
The $3,500 cap applies per contract, not per account. You can hold multiple contracts simultaneously, but no single market position can exceed the cap. This was raised from $850 in a 2025 revision to the no-action agreement.
Liquidity & Execution
PredictIt's liquidity is highly uneven. Presidential elections and major Senate races attract substantial volume with reasonably tight spreads. Beyond those marquee events, liquidity drops off sharply — niche state races and policy markets can have wide spreads and shallow order books.
High Liquidity
- • Presidential elections
- • Congressional control
- • Major Senate races
- • High-profile nominations
Spreads: tighter (varies by event)
Medium Liquidity
- • Policy outcomes
- • Senate seat control
- • Budget negotiations
- • Major economics data
Spreads: moderate (varies by timing)
Low Liquidity
- • State-level races
- • Niche policy props
- • Far-dated markets
- • Sports markets
Spreads: wide (thin order books)
The $3,500 position cap also limits institutional participation, which reduces overall depth compared to licensed DCM platforms where larger positions are permissible.
Trust & Resolution Rules
PredictIt operates under CFTC oversight via its no-action letter, but the fund protection and resolution mechanisms are meaningfully different from a fully licensed DCM. Here's what you actually get — and where the gaps are.
CFTC Regulatory Oversight
PredictIt operates under a CFTC no-action letter and has been under CFTC oversight since 2014. This provides meaningful baseline regulatory accountability even without full DCM status.
Published Resolution Rules
Each market has published resolution criteria available on the market page. Resolution authority rests with PredictIt staff following documented rules, with an established history of outcomes.
Custodial Funds — Not Segregated
Unlike CFTC-licensed DCMs, PredictIt holds customer funds custodially rather than in fully segregated bank accounts. This means less protection if PredictIt faces financial difficulties. Kalshi's segregated fund model is more protective.
Edge Case: Market Cancellations
PredictIt has a history of market cancellations under ambiguous circumstances. Always read the resolution rules tab carefully before trading, especially on political markets with contested outcomes or changing circumstances.
Edge Case: Ambiguous Wording
Political markets can have resolution criteria that become contested when real-world events unfold unexpectedly. PredictIt staff make final resolution calls with limited dispute recourse for traders who disagree.
Taxes
Event contract taxation remains an evolving area. Here's what PredictIt traders need to know for 2026 filing.
1099 Reporting
PredictIt issues 1099 forms for users who meet IRS reporting thresholds. You'll receive these by January 31 for the prior tax year. Keep records of all trades regardless of whether you receive a 1099.
Ordinary Income
Event contract gains are generally treated as ordinary income, not capital gains — taxed at your regular income tax rate. The 10% profit fee PredictIt charges is deducted before 1099 reporting, but verify this with a tax professional.
Tax Disclaimer
This is general information, not tax advice. Event contract taxation is complex. Whether the 10% PredictIt profit fee is deductible as a trade expense and how the 5% withdrawal fee interacts with your tax basis are questions that require a qualified tax professional. Keep detailed records of all trades, fees paid, and net proceeds.

Who Should Use PredictIt?
Best For
Political market researchers
If U.S. politics is your primary focus, PredictIt has the longest public history and deepest community in political trading. Invaluable for research workflows.
Traders who prefer PredictIt's format
Long-time users with years of market intuition built on PredictIt's specific contract structures and resolution patterns.
Casual traders with small stakes
The $10 minimum deposit and $3,500 position cap make PredictIt accessible for low-stakes political trading without significant capital exposure.
Prediction market history enthusiasts
PredictIt is where modern U.S. prediction market history was made. Trading here connects you to a decade of political forecasting data.
Not Ideal For
High-volume traders
The 10% profit + 5% withdrawal fee structure compresses returns significantly at scale. A trader winning $10,000/year on PredictIt pays $1,000 in profit fees + ~$450 in withdrawal fees. The same edge on Kalshi would cost a fraction of that.
Sports, crypto, or weather traders
PredictIt simply doesn't offer these markets. If you want to trade Fed rate decisions, BTC milestones, or temperature records, use Kalshi or Polymarket.
Traders needing deep liquidity
Outside of presidential elections and major Senate races, PredictIt's order books are thin. Wide spreads on niche markets make entry and exit expensive.
Users who want licensed DCM protection
PredictIt operates under a legacy no-action letter, not a CFTC Designated Contract Market license. Funds are custodial rather than segregated. For maximum regulatory protection, Kalshi is the better choice.
Summary
PredictIt is the original U.S. prediction market — founded in 2014 with a loyal political trading community and a decade of historical data. For researchers, political junkies, and casual traders who love the format, it still offers genuine value. The platform has demonstrated staying power through years of CFTC scrutiny and the sale of Aristotle's licensed exchange entities to Underdog in March 2026.
The honest tradeoff: the dual-fee structure (10% on profits + 5% on withdrawals) is the platform's biggest handicap. Active traders who migrate to Kalshi will find dramatically lower costs for comparable political markets. PredictIt's natural home is the political researcher and the casual trader who values its specific community and format over fee efficiency.
In plain English: PredictIt takes a dime out of every dollar you earn, then takes another nickel from every dollar you withdraw. On a $100 profit, you'd keep about $80.50 after both fees.
