The landscape of prediction markets is shifting rapidly, with a high-stakes legal battle brewing between federal and state regulators. This conflict will determine not only who governs platforms like Kalshi and Polymarket but also how your profits and losses are taxed. Understanding this dispute is crucial for anyone trading event contracts, especially when cryptocurrency is involved.

The High-Stakes Battle for Prediction Markets Heats Up

A regulatory storm is gathering over the booming prediction market industry. At its center is a fundamental question: are event contracts a financial derivative or a form of gambling? The answer will have billion-dollar consequences for regulators, the platforms themselves, and every user calculating their tax bill.

On one side is the U.S. Commodity Futures Trading Commission (CFTC), the federal agency that oversees derivatives markets. The CFTC argues that prediction markets, which they call "event contracts," are financial instruments used for hedging risk and price discovery. On the other side are numerous state gaming commissions, which see these platforms as a new form of online betting that falls under their jurisdiction—and their tax authority.

The stakes are enormous. The total volume for prediction markets was estimated to be $44 billion in 2025, according to reporting cited by North Carolina State University's Poole College of Management poole.ncsu.edu. States, seeing a massive, untaxed revenue stream, are challenging the federal government's authority. In a February 2026 op-ed, CFTC Chairman Michael S. Selig noted that platforms face "an onslaught of state-driven litigation across the country, with nearly 50 active cases" cftc.gov. This regulatory clash has now escalated into direct legal action, creating significant uncertainty for traders.

Who Regulates Event Contracts: The CFTC vs. State Gaming Commissions

Understanding the two opposing arguments is key to grasping the potential tax implications. Each side's position is rooted in different laws and financial motivations.

The CFTC's Claim: Exclusive Federal Jurisdiction

The CFTC’s position is that Congress has already given it the authority to regulate these products. The agency grounds its claim in the Commodity Exchange Act (CEA), which grants the CFTC "exclusive jurisdiction" over commodity futures and swaps prokopievlaw.com.

In the eyes of the CFTC, an event contract—whether it's based on an election outcome, a future inflation rate, or the winner of a sporting event—is a type of derivative. It derives its value from an underlying event, similar to how an oil future derives its value from the price of oil.

Chairman Selig has been vocal, calling state-level lawsuits a "power grab" that "ignores the law and decades of precedent" cftc.gov. The agency points to a long history of overseeing these markets, beginning with its approval of the Iowa Electronic Markets in 1992.

The States' Counter-Argument: A Push for Tax Revenue

State governments argue that if it looks like a bet and pays out like a bet, it should be regulated—and taxed—like a bet. They see the CFTC's classification as a regulatory loophole that allows platforms to operate nationwide, even in states where online sports betting is illegal, while avoiding state-level taxes and licensing fees.

The financial incentive for states is massive. For example, North Carolina charges sports betting operators a $1 million upfront license fee and an 18% tax on gross wagering revenue. This generated over $132 million in tax collections for the state in 2025 alone, according to research from Poole College of Management poole.ncsu.edu. States see prediction markets as siphoning away this potential revenue, which funds public services, education, and state programs.

A Timeline of the CFTC's Recent Regulatory Onslaught

The conflict has escalated significantly in 2026, with the CFTC taking a newly aggressive stance to defend its jurisdiction.

February 17, 2026: The CFTC files an amicus ("friend of the court") brief in the U.S. Court of Appeals for the Ninth Circuit. The case involves a dispute between a prediction market operator and the Nevada Gaming Control Board. In its brief, the CFTC formally asserts that federal law preempts any state gaming regulations for CFTC-registered event contracts cftc.gov.
March 16, 2026: The Commission publishes an Advance Notice of Proposed Rulemaking (ANPR) in the Federal Register, signaling its intent to create a more comprehensive federal framework for prediction markets. This move is a clear step toward solidifying its regulatory control.
April 2, 2026: In a major escalation, the CFTC announces it has filed suit directly against the states of Arizona, Connecticut, and Illinois. The lawsuits seek to block these states from enforcing their gaming laws against CFTC-registered platforms, setting the stage for a landmark legal showdown.

Why This Fight Matters for Your Taxes: Three Potential Scenarios

The outcome of this regulatory war will directly impact how you report your prediction market activity and how much tax you pay. The key difference lies in whether your winnings are treated as capital gains or gambling income.

Feature	Scenario 1: CFTC Wins (Status Quo)	Scenario 2: States Win	Scenario 3: Hybrid Model
Regulator	CFTC (Federal)	State Gaming Commissions	CFTC & States (Split)
Tax Treatment	Capital Gains/Losses	Gambling Income/Losses	Mixed & Complex
Primary Tax Form	Form 8949 & Schedule D	Schedule 1 & Schedule A	Both, depending on the contract
Tax Rate on Gains	Short-term capital gains rates (same as ordinary income)	Ordinary income rates	Ordinary income rates
Loss Treatment	Losses offset gains. Up to $3,000 in net losses can offset ordinary income.	Losses can only offset gambling winnings. Requires itemizing deductions.	Extremely complicated; depends on contract type.

Scenario 1: CFTC Wins (The Status Quo Prevails)

If the courts side with the CFTC, event contracts will be definitively classified as commodity derivatives.

Tax Treatment: Your net profits are treated as short-term capital gains, taxed at your ordinary income tax rates (which range from 10% to 37% for the 2025 tax year, depending on your bracket).
Reporting: You report all your trades on IRS Form 8949, and the net result is carried to Schedule D (Capital Gains and Losses).
Losses: This is the most favorable scenario for traders with losses. You can use your losses to offset any other capital gains (from stocks, crypto, etc.). If you have more losses than gains, you can deduct up to $3,000 of net capital losses against your regular income each year, per IRS rules irs.gov.

Scenario 2: States Win (A Shift to Gambling Rules)

If states win the right to regulate prediction markets as gambling, the tax picture changes dramatically for the worse.

Tax Treatment: Your winnings are considered "Other Income" and are taxed at your ordinary income tax rate.
Reporting: You report your total winnings on Schedule 1 of your Form 1040.
Losses: This is the critical difference. According to the IRS, you can only deduct gambling losses if you itemize your deductions on Schedule A. Even then, you can only deduct losses up to the amount of your winnings irs.gov. You cannot use gambling losses to offset other income.

Scenario 3: A Hybrid Model Emerges

It's also possible that a court ruling or new legislation could split jurisdiction. For example, contracts based on economic data (e.g., inflation) might remain with the CFTC, while contracts on sports outcomes could be deemed gambling and fall to the states.

This would create a significant compliance headache. You would need to meticulously track which type of contract you traded and apply two different sets of tax rules on the same return. A platform like dTax would become indispensable, as it could potentially differentiate between contract types based on API data and apply the correct tax treatment automatically.

The Crypto Angle: How DeFi Prediction Markets Complicate Taxes

While the current legal battle focuses on centralized platforms like Kalshi, the world of decentralized finance (DeFi) adds another layer of complexity. DeFi prediction markets like Augur and Gnosis operate on public blockchains without a central company.

This creates several unique tax challenges:

Gas Fees: Every on-chain action—placing a trade, claiming a reward, adding liquidity—requires a gas fee paid in a cryptocurrency like ETH. Each gas fee payment is a disposal of your crypto, which is a taxable event that must be tracked.
Crypto-to-Crypto Transactions: Winnings are often paid out in stablecoins (like USDC) or a protocol's native token, not cash. Receiving these tokens is a taxable event. Subsequently swapping them for another crypto or cashing out to your bank account are additional, separate taxable events.
Jurisdictional Chaos: If it's unclear who regulates a US-based company like Polymarket, it's even less clear who regulates a global, decentralized software protocol.

Manually tracking these countless micro-transactions is a near-impossible task. This is where a comprehensive crypto tax software is essential. dTax can connect directly to your wallets to automatically import and categorize every transaction, from the initial trade and associated gas fee to the final crypto-to-fiat conversion, ensuring no taxable event is missed.

How to Prepare Your Taxes Amid Regulatory Uncertainty

While the experts battle it out in court, you still have a tax filing obligation. Here’s what you can do to prepare:

Keep Meticulous Records: Regardless of the outcome, the IRS requires you to report your income. Keep detailed records of every trade: date, platform, contract details, amount wagered, amount won or lost, and any transaction fees.
Assume the Status Quo (For Now): Until the courts or Congress rule otherwise, the prevailing guidance is to treat prediction market activity as capital gains and losses. Be prepared to file Form 8949.
Use a Dedicated Tax Tool: The complexity of these transactions, especially in DeFi, makes specialized software a necessity. dTax is designed to handle the nuances of event contracts and crypto transactions, helping you generate the necessary tax forms, including Form 8949, with accuracy.

Frequently Asked Questions

Are winnings from prediction markets like Polymarket considered gambling income?

Currently, under CFTC guidance, they are not. They are treated as derivatives, and the resulting profits are taxed as short-term capital gains. You report these on Form 8949. However, this classification is the core issue being challenged by state regulators, so this treatment could change in the future depending on court rulings.

What happens if I lose money on a prediction market?

Under the current capital gains treatment, your losses are valuable. You can use them to offset other capital gains from stocks or crypto. If your total capital losses exceed your gains, you can deduct up to $3,000 of that net loss against your ordinary income per year. This is significantly more flexible than the rules for gambling losses, which can only offset gambling winnings.

Do I have to report my prediction market activity if I didn't cash out to my bank account?

Yes. A taxable event occurs when you close your position in a contract and realize a gain or loss, not when you transfer the money to your bank. For example, if you win a contract and are paid in USDC stablecoins, you have a taxable gain at that moment, based on the fair market value of the USDC you received. Swapping that USDC for another asset or cashing out to USD are separate transactions with their own tax consequences.
