Are Prediction Markets Legal in the US? Tax & Compliance

The Current Legal Landscape for Prediction Markets in the US

Prediction markets in the United States occupy an uncertain legal position that has evolved significantly since their emergence in the early 2000s. Unlike traditional financial markets, which operate under clear SEC or CFTC jurisdiction, prediction markets have largely avoided direct federal regulation by operating offshore or through legal interpretations that classify them differently from conventional derivatives.

The core issue is jurisdictional ambiguity. The Commodity Futures Trading Commission (CFTC) has authority over derivatives and futures contracts, which prediction markets superficially resemble. However, many platforms argue that their contracts—essentially binary bets on real-world events—fall outside this definition because they involve real-world outcomes rather than commodity prices. The SEC, meanwhile, has shown limited interest in regulating prediction markets, viewing them as distinct from securities trading.

In practice, this means that major platforms like Polymarket operate from offshore jurisdictions (Polymarket is based in the Cayman Islands) and explicitly restrict access to US residents through terms of service—though enforcement remains minimal. Other platforms have attempted to navigate US regulations more directly, with varying degrees of success and legal clarity.

The lack of explicit prohibition doesn't mean prediction markets are legal everywhere in the US. State-level gambling laws create additional complexity. Some states classify prediction markets as gambling, which can expose traders to liability depending on local statutes. Federal law, specifically the Unlawful Internet Gambling Enforcement Act (UIGEA) of 2006, prohibits financial institutions from processing payments for illegal gambling, but it explicitly exempts certain types of prediction markets—specifically those operated by exchanges regulated by the CFTC or those involving commodities or currencies.

Federal Regulation: CFTC, SEC, and the Gray Zone

The Commodity Futures Trading Commission has been the primary federal body examining prediction markets, though its approach has been cautious and limited. In 2007, the CFTC granted relief to the Iowa Electronic Markets (IEM), a university-operated prediction market focused on political and economic events. This relief allowed IEM to operate without full CFTC registration, establishing a precedent that certain prediction markets could exist outside standard derivatives regulation.

However, this relief was narrowly tailored to IEM's specific structure: it's operated by a university, involves no real money (only play money), and serves primarily educational purposes. It does not create a blanket exemption for commercial prediction markets accepting real money from the general public.

In 2022, the CFTC took a more aggressive stance, issuing enforcement actions and warnings against platforms offering prediction markets without proper registration or exemptions. The agency has signaled that it views many prediction markets as unregistered derivatives exchanges or futures contracts, bringing them squarely within CFTC jurisdiction. This has created a chilling effect on some platforms, particularly those attempting to serve US users directly.

The SEC has largely stayed out of the prediction market space, viewing most contracts as neither securities (they don't represent ownership or debt instruments) nor investment contracts under the Howey test. However, if a prediction market platform itself issued tokens or conducted an ICO, the SEC would likely assert jurisdiction over those offerings.

The practical result: prediction markets exist in a legal limbo. Platforms either operate offshore and serve US traders informally, or they attempt to structure themselves as exempt under narrow CFTC relief provisions. Neither approach is risk-free.

State-Level Gambling Laws and Local Restrictions

While federal law creates one layer of uncertainty, state gambling laws add another. Prediction markets could theoretically be classified as gambling in states with broad anti-gambling statutes, though enforcement against individual traders is rare.

States vary widely in their approach. Some states, like Nevada, have relatively permissive gambling laws and have shown interest in regulating prediction markets more formally. Others, like Utah, have strict prohibitions on gambling that could theoretically encompass prediction markets. Most states fall somewhere in between, with ambiguous statutes that don't explicitly address prediction markets.

The distinction between "gambling" and "prediction markets" often hinges on whether the activity is considered a game of chance versus a game of skill or information. Prediction markets are typically defended as the latter—traders succeed based on their ability to assess probabilities and gather information, not pure luck. However, this argument has not been tested in court for most prediction markets, leaving the legal status uncertain.

In practice, state enforcement against individual traders is minimal. Regulators are more likely to target the platform operators than individual users. Still, traders in states with strict gambling laws should be aware of the theoretical risk.

Tax Obligations: What the IRS Expects

Regardless of the legal ambiguity surrounding prediction markets themselves, the Internal Revenue Service has a clear position: all income derived from prediction market trading is taxable. This is perhaps the most straightforward legal requirement for US traders.

The IRS treats prediction market winnings as either ordinary income or capital gains, depending on the trader's specific situation and the classification of the activity. For most casual traders, winnings are likely classified as ordinary income, taxable at marginal rates. For traders who engage in frequent, substantial trading activity, the IRS might classify the activity as a "trade or business," which has different implications for deductions and self-employment tax.

Here's what traders need to know:

• Reporting requirement: All prediction market gains must be reported on your tax return. The IRS doesn't care that the platform is offshore or unregulated—taxable income is taxable income.
• Form 1099 complications: Most offshore prediction market platforms do not issue 1099 forms to US traders, since they're not US-regulated entities. This means you're responsible for tracking and reporting your own gains. The IRS expects you to maintain detailed records of all trades.
• Ordinary income vs. capital gains: If you're a casual trader, your gains are likely ordinary income. If you're a full-time trader or engage in substantial trading activity, you may qualify for "trader" status, which allows you to deduct trading expenses and potentially claim capital gains treatment. This is complex and requires professional guidance.
• Loss deductions: If you incur losses, you can generally deduct them against gains. However, the rules for deducting losses vary depending on whether you're classified as a trader or investor.
• Self-employment tax: If your prediction market activity is substantial and classified as a trade or business, you may owe self-employment tax in addition to income tax.

The practical challenge is that offshore platforms typically don't provide the documentation needed to file taxes accurately. Traders must manually track all transactions, calculate gains and losses, and report them to the IRS. Failure to do so can result in penalties, interest, and potential criminal charges for tax evasion.

Record-Keeping and Compliance Best Practices

Given the legal and tax complexity, traders should establish robust record-keeping practices from the start. This serves two purposes: it ensures accurate tax reporting and it provides documentation if the IRS ever questions your filings.

At minimum, maintain records that include:

• Date and time of each trade
• Description of the contract (what event it predicted)
• Amount wagered or invested
• Outcome and amount won or lost
• Exchange rate (if applicable) at the time of the trade and when proceeds were withdrawn
• Any fees paid to the platform

Many prediction market platforms provide trade history exports or APIs that allow traders to download transaction data. Use these tools to maintain organized records. Consider using tax software designed for traders or consulting a CPA who understands cryptocurrency and derivatives trading, as they'll be familiar with similar record-keeping requirements.

Additionally, maintain documentation of your methodology and research. If the IRS questions your trading activity, demonstrating that you're engaged in a legitimate information-gathering and analysis process strengthens your position. This is particularly important if you're claiming "trader" status for tax purposes.

Finally, consider the jurisdictional issue when choosing a platform. Platforms that explicitly restrict US access (like some fully compliant exchanges) may offer better legal clarity, even if they're less convenient. Platforms that operate offshore and serve US traders informally carry higher regulatory risk but may offer better odds or more markets. Weigh these factors based on your risk tolerance and the scale of your trading.

Regulatory Trends and Future Outlook

The legal landscape for prediction markets in the US is evolving. Several trends suggest the regulatory environment may become clearer—though not necessarily more permissive—in the coming years.

First, there's growing interest in prediction markets among policymakers and academics. Some economists and policy experts advocate for regulated prediction markets as tools for forecasting and decision-making. This has led to proposals for legislative frameworks that would create explicit exemptions or licensing regimes for prediction markets. However, these proposals remain in early stages and face opposition from gambling interests and other stakeholders.

Second, the CFTC has signaled that it may pursue more enforcement actions against unregistered platforms. The agency has the authority and apparent willingness to shut down or restrict prediction market platforms that don't comply with derivatives regulation. This could push more platforms toward either offshore operations or explicit regulatory compliance.

Third, there's potential for state-level regulation. Some states are exploring frameworks that would explicitly permit and regulate prediction markets. These could provide legal clarity for traders in those states, though they might also impose restrictions or licensing requirements.

For traders in 2026, the practical implication is that the legal status remains uncertain but the tax obligation is clear and unchanging. Expect continued regulatory scrutiny of platforms, but don't expect that scrutiny to affect individual traders' tax obligations.

Choosing a Platform: Legal and Practical Considerations

When evaluating prediction market platforms, consider both legal and practical factors:

Offshore platforms (like Polymarket): These operate outside US jurisdiction and typically don't restrict US access, though their terms of service may discourage it. Advantages include broader markets, higher liquidity, and no KYC (know-your-customer) requirements. Disadvantages include regulatory uncertainty, lack of consumer protections, and the responsibility for tax reporting falls entirely on you.

Compliant or semi-compliant platforms: Some platforms attempt to operate within US regulatory frameworks, either through CFTC exemptions or by restricting access to non-US residents. These offer greater legal clarity and may provide better documentation for tax purposes. However, they may have fewer markets or lower liquidity.

Play-money platforms: Some platforms operate with play money rather than real money, which sidesteps many legal issues. These are clearly legal but lack financial stakes and real-world trading dynamics.

The best prediction markets for your situation depend on your priorities: legal certainty, market variety, liquidity, or tax documentation. There's no universally "best" choice, but understanding the legal implications of each platform type helps you make an informed decision.

Frequently Asked Questions

Can I legally trade on prediction markets in the US?

Legally, it's complicated. Most prediction markets operate in a gray zone—not explicitly prohibited by federal law but also not explicitly permitted. Offshore platforms serve US traders informally. State-level gambling laws add another layer of uncertainty. Tax authorities clearly expect you to report all gains. If you choose to trade, do so with awareness of the regulatory risks and tax obligations.

Do I have to report prediction market winnings to the IRS?

Yes, absolutely. All prediction market gains are taxable income. The IRS doesn't care that the platform is offshore or unregulated. You're responsible for tracking and reporting all gains, even if the platform doesn't issue a 1099 form.

What if I lose money on prediction markets?

You can generally deduct losses against gains. If your losses exceed gains, you may be able to carry losses forward to future years, though the rules are complex. Consult a tax professional for specific guidance on your situation.

Is prediction market trading considered gambling?

It depends on the jurisdiction and the specific market. Some states might classify it as gambling, while others wouldn't. Federal law provides exemptions for certain types of prediction markets. The distinction often hinges on whether the activity involves skill or chance. Most prediction market advocates argue that successful trading requires skill and information analysis, not luck.

Should I use a VPN to access prediction markets?

Using a VPN to circumvent geographic restrictions violates the terms of service of most platforms and could expose you to legal or account-closure risks. It's not recommended. If you're concerned about legal access, research platforms that explicitly permit US traders or consult a lawyer in your jurisdiction.

What documentation do I need for the IRS?

Maintain detailed records of all trades, including dates, amounts, outcomes, and gains or losses. Export transaction history from your platform if possible. If you're claiming "trader" status, document your research methodology and decision-making process. Keep records for at least seven years, as that's the IRS's standard audit period.

Final Thoughts: Navigate Carefully

Prediction markets offer genuine opportunities for informed traders to profit from their forecasting ability. However, the legal landscape in the US remains uncertain, and tax obligations are unambiguous. Before trading significant amounts, understand the regulatory risks in your jurisdiction, establish robust record-keeping practices, and consult a tax professional. The combination of legal ambiguity and clear tax expectations means that responsible traders must be proactive about compliance, even when the regulatory environment itself is unclear.
