PredictIt is one of the longest-running real-money political prediction markets in the United States, built around the idea that people with skin in the game make better political forecasts than polls alone. It operates under a specific regulatory arrangement — a CFTC no-action letter — which has shaped almost everything about how the platform is structured: the small per-market position caps, the politics-only focus, the academic-research framing. Understanding those constraints explains why PredictIt works the way it does.

TL;DR

• PredictIt is a US-accessible, real-money political prediction market operated under a CFTC no-action framework.
• Per-market position caps (as of this writing, $850 per market; verify directly with PredictIt for current terms) keep individual exposure small.
• Fees are higher than most alternatives — check current terms at predictit.org before trading.
• Markets cover US politics almost exclusively: elections, nominations, legislative outcomes, approval ratings.
• Use CoinRithm's PredictIt hub to browse live PredictIt markets and odds without creating an account. CoinRithm is not PredictIt and does not execute real trades.

What Is PredictIt

PredictIt is a real-money prediction market where users buy and sell shares on political outcomes — primarily US elections, legislative events, nominations, and approval ratings.

It was founded with an academic-research mission and is operated by Victoria University of Wellington, a New Zealand university, under a CFTC no-action letter that permits it to operate in the US under conditions that keep its scale limited. That regulatory framing is not a technicality — it is the foundation of PredictIt's entire design.

Unlike crypto-native platforms, PredictIt requires no blockchain wallet. You can fund an account with standard payment methods and trade directly in dollars. The trade-off is the structural constraints baked into the no-action framework: small position caps, a narrower market catalog, and fees that are higher than most newer alternatives.

Ground truth: PredictIt's regulatory status has been contested. In 2022, the CFTC moved to revoke its no-action letter. PredictIt challenged that in court and, as of mid-2026, continues to operate. Regulatory status can change. Before depositing real money, verify PredictIt's current operational status and your own jurisdiction's rules at predictit.org.

How the CFTC No-Action Letter Works

A no-action letter from the CFTC is not a license. It is a statement that the CFTC staff will not recommend enforcement action against a platform that meets specific conditions. PredictIt's conditions are what create its characteristic structure.

The conditions included requirements like:

• Limiting market participation to a capped number of traders per market
• Capping individual investment per market at a set dollar amount
• Operating for academic and research purposes, not pure commercial trading
• Reporting market data to academic researchers

These are the reasons PredictIt is politics-only (narrower scope is easier to justify under the research framing), why position caps exist (keeping stakes small limits the commercial-trading argument), and why its user base has stayed relatively niche compared to CFTC-regulated exchanges like Kalshi that hold full CFTC designation as Designated Contract Markets (DCMs).

How PredictIt Works

The core mechanics are the same as any prediction market.

1. Markets are created around specific political questions with defined outcomes, resolution rules, and an end date.

2. Users buy shares in one or more outcomes. Share prices range from $0.01 to $0.99 and reflect the market's collective estimate of the probability of that outcome.

3. Prices shift as new information arrives — polling, news, endorsements, official announcements. Traders update positions accordingly.

4. The market resolves when the real-world event occurs, according to rules defined when the market was created.

5. Winners collect $1.00 per share. Losers' shares become worthless.

Simple example:

A market asks: "Will the Democratic candidate win the presidential primary in State X?"

If "Yes" shares are priced at $0.62, the market implies roughly a 62% probability. If you buy Yes shares at $0.62 and that outcome resolves, each share pays $1.00 — a profit of $0.38 per share, before fees.

Resolution rules are specific. PredictIt defines what sources it uses to resolve markets, what counts as a qualifying outcome, and what happens in edge cases (withdrawn candidates, delayed results). Read the rules for each market before buying.

PredictIt's Market Focus

PredictIt's catalog is almost entirely US politics. That is both its strength and its principal limitation.

Markets you will find on PredictIt:

• Presidential election outcomes (national and by state)
• Congressional races (House and Senate seats)
• Presidential approval ratings
• Cabinet nominations and Senate confirmation outcomes
• Legislative and budget outcomes
• Party primary outcomes
• Governor and Senate special elections

Markets you will not find:

• Crypto price outcomes
• Sports outcomes
• Geopolitics (non-US)
• Entertainment
• Economic indicator markets (Fed rate decisions, GDP, etc.)

For users who want to trade on US political events specifically, this narrow focus is a feature — PredictIt often has the deepest liquidity on US political races, with active traders who follow the political calendar closely. For users who want broader market variety, PredictIt will feel limiting fast.

Fees and Position Caps

This is where PredictIt diverges most sharply from competitors. Verify current terms at predictit.org before trading, as these can change.

As of this writing (mid-2026):

What those fees mean in practice:

Suppose you invest $100, win, and net $40 in profit on a market. PredictIt takes 10% of that profit ($4.00). Then when you withdraw, you pay 5% on the amount withdrawn. On a $140 withdrawal, that is another $7.00. Total fee drag: $11.00 on a $40 profit.

That is a meaningful percentage of your return, especially on smaller positions. For full side-by-side fee comparisons across platforms, read Prediction Market Fees Comparison.

The position cap is both a constraint and a feature. A hard cap of ~$850 per market means your maximum loss on any single market is bounded. That appeals to casual political observers who want to put a small, defined amount of money on an election outcome without worrying about runaway exposure. It also means you cannot scale a winning edge — serious traders who find good opportunities hit the ceiling quickly.

PredictIt vs Other Platforms

The short comparison relevant to the most common questions:

PredictIt vs Kalshi:

Kalshi is a CFTC-registered Designated Contract Market (DCM), which means it operates under a full exchange license rather than a no-action letter. Kalshi accepts US residents, has broader market categories (economics, weather, entertainment alongside politics), allows larger position sizes, and generally has lower fees. For most US users interested in political markets, Kalshi has become the stronger option — though PredictIt's community around US elections remains engaged.

PredictIt vs Polymarket:

Polymarket is a crypto-native platform that requires a crypto wallet and USDC on Polygon. Its fee structure is lower and its market catalog is far broader, but US access is restricted. PredictIt is the reverse: US-accessible, politics-only, no crypto required.

How CoinRithm Covers PredictIt Markets

CoinRithm aggregates prediction markets from multiple sources — including PredictIt — and surfaces them in one place for research. You do not need a PredictIt account to see what is trading or at what odds.

What CoinRithm shows for PredictIt markets:

• Live market odds and probability for each outcome
• Odds history (how prices have moved over time)
• Market volume and activity
• Resolution rules pulled from PredictIt
• Cross-source comparison (see if a similar market exists on Kalshi or Polymarket at different odds)

The PredictIt hub on CoinRithm is the starting point for this. You can also browse the full prediction markets hub for all sources combined, or use the compare page to see the same event priced differently across platforms.

CoinRithm is not PredictIt. CoinRithm does not execute real trades and is not a broker. What you see on CoinRithm is aggregated data for research.

Researching PredictIt Markets Before Trading

The strongest use of CoinRithm before touching real money on PredictIt is in the research and calibration phase.

Paper trading on CoinRithm:

CoinRithm's mock trading feature lets you take positions on prediction market events using simulated USD (minimum $10) before risking real money anywhere. This is useful for:

• Testing whether your read on a political race is correct before committing real dollars
• Understanding how odds move during an election cycle
• Getting comfortable with position sizing without actual financial risk

This is not PredictIt paper trading — CoinRithm's mock system is entirely separate from PredictIt. But it covers the same markets, which makes it a useful calibration tool.

Odds history:

Before buying on PredictIt, check whether the price you are seeing is near a peak or a trough in recent movement. The odds history charts on CoinRithm show this. Buying at $0.80 on a market that was at $0.55 three weeks ago and just spiked on a single news story is a different decision than buying at $0.80 on a market that has been stable for months.

Cross-platform comparison:

If the same real-world event is priced at 70% on PredictIt and 62% on Kalshi, that gap is meaningful. Cross-platform price differences exist because different platforms have different trader bases, liquidity conditions, and market structures. The compare page surfaces these discrepancies.

Resolution rules:

Before any trade, read the resolution rules for that specific market. PredictIt's rules define exactly what counts — which source they use, what happens in delayed results, what happens if a candidate withdraws. Misreading the rules is the most common beginner mistake across all prediction market platforms.

Is PredictIt Legal and Safe

Legal status:

PredictIt operates under a CFTC no-action letter that has been in active legal dispute. As of mid-2026, it continues to operate. Its long track record — over a decade of US political markets — reflects the stability of its core model, but the regulatory situation is more complex than a simple "yes, it is licensed" answer.

For US residents, PredictIt is the clearest pathway to real-money US political prediction markets without needing cryptocurrency. It is not a fully-licensed exchange in the way Kalshi is. Always verify current operational and legal status before depositing.

Platform safety:

PredictIt has operated for over a decade and has an established track record of resolving markets and processing withdrawals. It is not a fly-by-night operation. The practical risks are:

• Regulatory change could affect account access or the ability to withdraw
• Markets occasionally produce disputes about resolution (PredictIt has a defined process for these)
• The fee structure means you need to win meaningfully to net a real return

Risk factors to manage:

1. Position caps mean per-market exposure is bounded, which limits catastrophic loss but also limits return
2. Read resolution rules before every trade
3. Verify PredictIt is available in your jurisdiction — check directly with PredictIt
4. Only use money you can afford to lose; prediction markets are not guaranteed income

Common Mistakes

Not reading resolution rules. Markets resolve on specific criteria. A "Yes" resolution might require a formal nomination to the Senate — not just a media announcement. Read the rules for every market before buying.

Ignoring fees. PredictIt's fee structure is high relative to alternatives. A trade that looks profitable at face value may net very little after the 10% profit fee and 5% withdrawal fee are applied. Calculate actual returns, not just win/loss.

Treating polls as prices. A candidate polling at 60% nationally is not the same as a market pricing them at 60%. Markets incorporate information polls do not, including money, time, and trader incentives. They can diverge significantly — and either can be wrong.

Assuming the cap is a limit on risk. The ~$850 per-market cap limits how much you can put in per market. It does not prevent you from holding multiple markets simultaneously, or from being wrong across many markets at once.

Not checking odds history. A price of $0.75 means very different things depending on whether it moved there from $0.40 last week or has sat there for months. Use CoinRithm's odds history charts before making the trade.

Confusing probability with certainty. An 85% implied probability still means a 15% chance of being wrong. High-confidence markets can and do resolve against the favorite.

Frequently Asked Questions

What is PredictIt in simple terms

PredictIt is a website where you can buy and sell shares on US political outcomes using real money. If you buy a "Yes" share at $0.60 and that outcome happens, your share pays $1.00. If it does not happen, your share is worth nothing. Prices represent what the market collectively thinks the probability of each outcome is.

Is PredictIt legal in the US

PredictIt operates under a CFTC no-action letter, which means CFTC staff committed not to pursue enforcement while PredictIt met specific conditions. That arrangement has been disputed legally and its status has changed over time. As of mid-2026, PredictIt is operating. Verify current status directly with PredictIt before depositing money.

How does PredictIt make money

PredictIt charges a 10% fee on profits per market and a 5% fee on withdrawals, as of this writing. These are materially higher than most competing platforms. Check current fee terms at predictit.org, as terms can change.

What is the PredictIt position limit

As of mid-2026, PredictIt caps individual investment per market at approximately $850. This limit stems from the conditions of its CFTC no-action arrangement. Verify the current cap directly with PredictIt, as it is subject to change.

Does PredictIt require cryptocurrency

No. PredictIt uses US dollars and accepts standard payment methods like bank transfer and card. You do not need a crypto wallet.

What markets does PredictIt offer

PredictIt focuses almost exclusively on US political markets: presidential and congressional elections, nominations, approval ratings, legislative outcomes, and primary races. It does not offer crypto, sports, or entertainment markets.

Can I research PredictIt markets without creating an account

Yes. CoinRithm's PredictIt hub shows live PredictIt market odds, odds history, and resolution rules without requiring a PredictIt account. CoinRithm is not PredictIt and does not execute real trades.

How is PredictIt different from Kalshi

Kalshi holds a full CFTC Designated Contract Market (DCM) license, accepts all US residents, offers a broader range of markets, and generally has lower fees. PredictIt operates under a no-action letter with strict position caps and a politics-only catalog. For most US users, Kalshi now provides a more robust regulated option — but PredictIt retains a dedicated community around US election markets.

Can I paper trade PredictIt markets

Not on PredictIt itself. CoinRithm offers mock trading on prediction market events (including events sourced from PredictIt) using simulated USD, with a $10 minimum per position. This is CoinRithm's own simulated trading feature — it is not connected to PredictIt and does not involve real money.

What happens when a PredictIt market resolves

Winning shares pay $1.00 each. Losing shares pay $0.00. PredictIt takes its 10% profit fee on net gains per market at resolution. You can then withdraw remaining funds, subject to the 5% withdrawal fee.

Conclusion

PredictIt occupies a specific and durable niche in the prediction market landscape: US-accessible, fiat-funded, politics-only, built for casual political traders who want real stakes without crypto complexity. Its constraints — the position caps, the politics-only catalog, the higher fees — are not accidents. They are structural outcomes of the regulatory arrangement that allows it to operate.

For US political events specifically, PredictIt has depth and an established community. For users who want broader market variety, lower fees, or larger position sizes, alternatives like Kalshi now offer a more direct regulated path.
