Are Prediction Markets Legal? A 2026 Regulatory Guide

"Are prediction markets legal?" is the first question most people ask when they discover platforms like Kalshi and Polymarket. The answer is nuanced — it depends on where you live, which platform you use, and what you're trading. But the short answer for US residents in 2026: yes, prediction markets are legal, and the regulatory landscape is more favorable than it's ever been.

This guide covers everything you need to know about prediction market legality: federal regulation, state-by-state access, tax obligations, and the regulatory status of each major platform.

The Federal Regulatory Framework

Prediction markets in the United States are primarily regulated by the Commodity Futures Trading Commission (CFTC), the same federal agency that oversees futures and options trading on commodity exchanges.

The CFTC classifies prediction market contracts as event contracts — binary options that pay out based on whether a specific real-world event occurs. These are legally distinct from sports betting (regulated by state gaming commissions) and securities (regulated by the SEC).

How the CFTC Regulates Prediction Markets

The CFTC's authority over prediction markets is established through the Commodity Exchange Act (CEA). Under the CEA, exchanges that list event contracts must either:

Register as a Designated Contract Market (DCM) — the full regulatory framework that Kalshi has achieved
Obtain a no-action letter — a temporary regulatory accommodation (like PredictIt's arrangement)
Operate outside CFTC jurisdiction — applicable to platforms that don't serve US customers (like Polymarket)

The DCM registration is the gold standard. It requires the exchange to:

Maintain minimum capital requirements
Segregate customer funds from company assets
Implement market surveillance programs
Submit to regular CFTC audits and reporting
Comply with anti-money laundering (AML) and know-your-customer (KYC) requirements
Maintain adequate technology safeguards

The 2024 Election Market Watershed

A landmark moment for prediction market regulation came when Kalshi won its federal court case to list election event contracts. The CFTC had initially opposed political event contracts, arguing they were similar to gaming. A federal judge disagreed, ruling that political event contracts were legitimate hedging and information-discovery tools that fell within the CEA's framework.

This ruling effectively confirmed that:

Political prediction markets are legal under federal law
The CFTC cannot ban event contracts simply because they relate to elections
Prediction markets serve a legitimate economic purpose (price discovery, hedging, information aggregation)

The decision opened the door for Kalshi to offer a full suite of political markets and strengthened the legal foundation for the entire prediction market industry.

Platform-by-Platform Legal Status

Kalshi: Fully Regulated

Legal status: CFTC-registered Designated Contract Market (DCM)

Kalshi has the strongest legal standing of any prediction market platform. Its DCM designation means:

Available in all 50 US states — no geographic restrictions for US residents
Segregated customer funds — your deposits are held in FDIC-insured bank accounts, separate from Kalshi's corporate funds
1099 tax reporting — Kalshi issues annual tax forms to the IRS
CFTC oversight — regular audits, compliance requirements, and market surveillance
Deposit insurance — customer funds held in FDIC-insured banks (up to federal limits)

If you're a US resident and want to trade prediction markets with maximum legal protection, Kalshi is the definitive choice.

Risk factors: Regulatory frameworks can change. Congress could theoretically pass legislation restricting event contracts, and the CFTC could impose new rules on DCMs. However, after the 2024 court ruling and the industry's growth, significant regulatory rollback is considered unlikely.

PredictIt: Regulatory Gray Area

Legal status: Operating under a CFTC no-action letter (contested)

PredictIt operates under a 2014 no-action letter from the CFTC, which essentially says the Commission won't take enforcement action against the platform as long as it meets certain conditions:

Operated for academic research purposes by Victoria University of Wellington
Individual position limits of $850 per market
Maximum of 5,000 active traders per market
No institutional or algorithmic trading

The legal situation has been unstable:

2022: The CFTC moved to withdraw the no-action letter, arguing PredictIt had evolved beyond its academic research purpose into a commercial operation
2023: A federal court temporarily blocked the withdrawal
2024-2026: Legal proceedings continue with no final resolution

What this means for traders: PredictIt is currently legal to use. However, its long-term legal status is genuinely uncertain. Traders should:

Not keep large balances on the platform unnecessarily
Be prepared for a scenario where PredictIt is required to wind down
Consider Kalshi as a more legally stable alternative

Polymarket: Outside US Jurisdiction

Legal status: Not registered with the CFTC; US residents face restrictions

Polymarket operates on blockchain infrastructure and is not registered with any US financial regulator. The platform officially restricts US residents from creating accounts and trading.

How this works in practice:

Polymarket blocks US IP addresses from depositing funds
New account creation requires verification that may screen for US residency
The platform's terms of service prohibit US persons from trading

Legal risk for US residents: Using Polymarket from the US involves potential legal risk. While no individual US trader has been prosecuted for using Polymarket, the platform itself settled with the CFTC in 2022 for operating an unregistered exchange and paid a $1.4 million fine. The CFTC's position is clear: US residents should use CFTC-regulated platforms.

For non-US residents: Polymarket is the largest and most liquid prediction market globally. In most international jurisdictions, using Polymarket is not restricted by local law, though regulations vary by country.

Metaculus: No Regulatory Issues

Legal status: Not a financial exchange; reputation-based only

Since Metaculus doesn't involve real-money trading, it falls entirely outside financial regulations. There are no legal restrictions on using Metaculus from any jurisdiction. It's simply a website where you make predictions and track your accuracy.

Manifold: Mostly Play Money

Legal status: Play-money component is unregulated; sweepstakes markets operate under partner license

Manifold's primary play-money system (using "mana") is not a financial product and faces no regulatory restrictions. Their real-money "sweepstakes" markets operate through a licensed partner entity that provides regulatory compliance.

State-by-State Considerations

Unlike sports betting, which requires state-by-state legalization, prediction markets regulated by the CFTC are governed by federal law and are available nationwide.

Kalshi: Available in all 50 states + DC. Federal CFTC regulation preempts state gambling laws for properly registered exchanges.

PredictIt: Available to all US residents under the current no-action letter arrangement.

Sports betting comparison: As of 2026, sports betting is legal in approximately 38 states plus Washington DC. Prediction markets have a meaningful access advantage — residents of states that prohibit sports betting can still legally use Kalshi.

States With Special Considerations

Some states have broad gambling definitions that could theoretically capture prediction markets. However, the CFTC's federal authority over event contracts has, to date, been sufficient to preempt state-level concerns. No state has successfully blocked a CFTC-regulated prediction market from serving its residents.

Tax Obligations

Prediction market profits are taxable income in the United States. Here's what you need to know:

How Profits Are Taxed

The IRS treats prediction market gains as income. The specific tax treatment depends on the type of contract and how it's classified:

Kalshi contracts: May qualify as Section 1256 contracts under the Internal Revenue Code, which provides a favorable tax treatment:

60% of gains taxed at the long-term capital gains rate (0-20%)
40% of gains taxed at the short-term rate (ordinary income, 10-37%)
This blended rate is advantageous for most traders
Losses can be carried back 3 years or forward indefinitely

Note: Tax treatment is subject to IRS interpretation and may vary. Consult a tax professional for your specific situation.

PredictIt winnings: Reported on 1099-MISC as other income. Taxed at ordinary income rates. The 10% profit fee PredictIt charges is deductible as a trading expense.

Polymarket profits: No US tax forms are issued. Traders are responsible for self-reporting all gains and losses. Crypto-to-crypto transactions may trigger additional taxable events.

Reporting Requirements

Kalshi issues 1099 forms annually, making tax compliance straightforward. Your broker integration or tax software can import these directly.

PredictIt issues 1099-MISC for net winnings above the reporting threshold.

Polymarket and other crypto platforms don't issue US tax forms. You must maintain your own records of:

Every trade (date, market, shares, price, fees)
Conversion transactions (USD to USDC, USDC to USD)
Resolution payouts
Net gains and losses

Record-Keeping Best Practices

Regardless of platform, maintain records of:

Trade log: Date, platform, market name, side (Yes/No), shares, entry price, fees
Resolution log: Date, outcome, payout, exit fee
Deposit/withdrawal log: Dates, amounts, conversion rates (for crypto platforms)
Annual summary: Net P&L per platform, total fees paid, tax owed

Many traders use spreadsheets or portfolio tracking tools. Your Prediction Edge offers portfolio tracking that can help organize your trades across platforms.

Anti-Money Laundering (AML) and Know Your Customer (KYC)

Regulated prediction markets must comply with federal AML and KYC requirements:

Kalshi KYC

Government-issued ID verification required
Social Security Number required for tax reporting
Address verification
Sanctions screening

PredictIt KYC

Government ID and SSN required
Address verification
Background checks

Polymarket KYC

Varies — some features require ID verification through partners
Crypto wallets can be used pseudonymously for basic trading
Enhanced verification may be required for larger deposits

KYC requirements serve two purposes: preventing money laundering and ensuring accurate tax reporting. They're standard across all regulated financial platforms and shouldn't be a concern for legitimate traders.

International Legal Landscape

Prediction market regulation varies significantly by country:

Generally Permissive

United Kingdom — gambling-regulated platforms like Betfair cover event markets
Australia — prediction markets allowed under gambling regulation
Canada — limited regulation, generally accessible
Most of EU — varies by country, generally accessible for non-regulated platforms

Restrictive

China — all gambling and speculative trading prohibited
India — legal status unclear; varies by state
Saudi Arabia — gambling prohibited

Evolving

Japan — crypto-related regulation rapidly evolving
South Korea — gambling restrictions but crypto trading permitted
Brazil — new regulatory framework for digital assets under development

For non-US traders, Polymarket is the most accessible platform with the deepest liquidity. Local regulations should be checked before trading on any real-money platform.

Frequently Asked Legal Questions

Is prediction market trading the same as gambling?

Legally, no. The CFTC classifies event contracts as derivatives, not gambling products. This distinction is based on the economic purpose of prediction markets: they serve as tools for price discovery, risk hedging, and information aggregation. The 2024 federal court ruling reinforced this classification by finding that political event contracts are legitimate financial instruments.

Practically, the activity has similarities to gambling (you're wagering money on uncertain outcomes), but the regulatory treatment is distinct.

Can I get in trouble for using Polymarket from the US?

No individual US trader has been prosecuted for using Polymarket. However, the platform officially restricts US residents, and using it involves violating the platform's terms of service. The CFTC's enforcement actions have been directed at the platform itself (the 2022 settlement), not individual users.

That said, using an unregulated offshore platform carries inherent risks: no fund protection, no regulatory recourse if something goes wrong, and potential future enforcement risk. US residents are better served by Kalshi.

Do I need to report small prediction market profits?

Yes. The IRS requires reporting of all income, including prediction market profits, regardless of amount. Kalshi and PredictIt issue tax forms that make this easy. For Polymarket, you're responsible for self-reporting.

Are prediction markets available to people under 18?

No. Kalshi requires users to be 18+. PredictIt also requires 18+. Polymarket's terms require users to be of legal age in their jurisdiction. Metaculus and Manifold (play money) may have lower age requirements.

Can a prediction market trade be reversed or voided?

On regulated platforms (Kalshi), markets resolve according to pre-published rules. Resolution disputes follow the platform's arbitration process, with CFTC oversight as a backstop. Trades are generally final once executed.

On unregulated platforms (Polymarket), resolution is handled by the platform's committee with UMA's oracle as a dispute resolution mechanism. There have been instances of disputed resolutions.

The Regulatory Outlook for 2026 and Beyond

The prediction market industry is on a strong legal trajectory:

Positive trends:

Kalshi's successful court challenge established strong legal precedent
Growing bipartisan political support for prediction markets as information tools
Increasing academic recognition of prediction market accuracy
CFTC under the current administration appears supportive of market innovation

Potential risks:

Congressional action could restrict specific event types (unlikely but possible)
State attorneys general could challenge federal preemption (untested)
A major market manipulation scandal could trigger regulatory backlash

Most likely outcome: Continued growth under the current regulatory framework, with potential for additional exchanges to receive DCM designation and more event types to be approved for trading.
