Why Tax Reporting for Prediction Markets Is Getting More Complex

The prediction market industry has exploded. Platforms like Kalshi now operate under full CFTC regulation, Polymarket handles hundreds of millions in volume monthly, and mainstream traders are flowing in from stock markets, sports betting, and crypto. With that growth comes increased IRS scrutiny.

The core challenge? Prediction markets don't fit neatly into any single tax box. Are your profits gambling winnings? Investment income? Derivative contract gains? The answer depends on the platform you used, how you structured your trades, and whether you used cryptocurrency to fund your account.

The IRS hasn't issued a definitive ruling specifically for prediction markets, but existing tax law — particularly around Section 1256 contracts, gambling income rules, and crypto property rules — absolutely applies. Ignoring this isn't an option in 2026, especially as platforms begin issuing 1099 forms more aggressively and the IRS cross-references third-party reporting data.

If you're newer to this space, the beginner's step-by-step guide to science and tech prediction markets is a great place to build your foundation before diving into the tax layer.

How the IRS Currently Classifies Prediction Market Income

This is the section most traders get wrong, and it's where mistakes get expensive.

Gambling Income vs. Investment Income

The IRS draws a clear line: gambling income is reported on Schedule 1 (line 8b), while investment income flows through Schedule D and Form 8949. The distinction matters because:

• Gambling losses can only offset gambling winnings (not other income), and only if you itemize deductions
• Capital losses can offset capital gains, with up to $3,000 per year deductible against ordinary income if losses exceed gains

The good news: regulated prediction markets like Kalshi — which are CFTC-regulated designated contract markets — are increasingly treated as financial instruments rather than gambling. This likely means Section 1256 treatment for eligible contracts, which gives you a favorable 60/40 split (60% long-term capital gains, 40% short-term) regardless of how long you held the position.

For crypto prediction market tax considerations, the rules layer further — since funding with crypto creates a separate taxable event at the point of conversion.

Section 1256 Contracts: The Trader's Best Friend

If your prediction market trades qualify as Section 1256 contracts, you automatically get:

• The 60/40 capital gains split (often saving traders 5-15% in taxes)
• The ability to carry back losses up to 3 years
• Mark-to-market accounting at year end

Whether your specific trades qualify depends on the platform's regulatory structure. Kalshi's CFTC-regulated contracts have a stronger case for Section 1256 treatment than offshore or crypto-settled markets. Consult a tax professional familiar with derivatives to confirm your platform's status.

Step-by-Step: How to Track and Report Your Prediction Market Profits

Here's a practical numbered process to follow from January through tax filing:

1. Download all transaction histories from every platform you used in 2025 (January through December). Most platforms offer CSV exports.
2. Categorize each trade — note the platform, contract type, entry price, exit price, and settlement date.
3. Identify your platform's regulatory status — CFTC-regulated (likely Section 1256), offshore/unregulated (likely gambling or other income), or crypto-settled (property rules apply).
4. Calculate your net profit or loss per platform — don't mix platform types when netting gains and losses.
5. Record crypto-funded trades separately — each time you converted crypto to fund a bet, log the fair market value of the crypto at conversion time. That's a taxable event on its own.
6. Check for 1099 forms — Kalshi and other regulated platforms may issue 1099-B forms. Match these to your own records.
7. Complete the correct forms — Form 6781 for Section 1256 contracts, Form 8949 + Schedule D for capital gains, Schedule 1 for gambling income.
8. Document your trader status if applicable — if you trade at high volume, you may qualify as a professional trader, unlocking additional deductions for software, subscriptions, and data services.

Platform Comparison: Tax Treatment by Market Type

Different platforms create very different tax situations. Here's a quick reference:

Platform Type	Regulatory Status	Likely Tax Treatment	Key Form
Kalshi	CFTC-regulated DCM	Section 1256 contracts	Form 6781
Polymarket (crypto)	Offshore / crypto-settled	Property (crypto rules)	Form 8949
Sports prediction markets	Varies / gambling-adjacent	Gambling income	Schedule 1
Binary options platforms	Varies	Section 1256 or gambling	Form 6781 or Sch. 1
Offshore prediction markets	Unregulated	Gambling or other income	Schedule 1

Key takeaway: Using multiple platforms means you may need to file multiple forms and follow multiple sets of rules in the same tax year. This is exactly why platform-specific record keeping from day one matters so much.

If you've been exploring Kalshi API trading strategies, note that algorithmic trades generate the same tax obligations as manual ones — sometimes with higher volume that makes record keeping even more critical.

Crypto-Settled Prediction Markets: The Double Tax Trap

Platforms like Polymarket settle in USDC or other crypto assets. This creates a two-layer tax problem that catches traders off guard every year.

Layer 1 — Funding your account: If you convert ETH or BTC to USDC to fund your trades, you've just sold a capital asset. The gain or loss on that crypto is immediately taxable, regardless of what you do next.

Layer 2 — Your actual prediction winnings: The profit from the resolved market is then taxed again, typically as either ordinary income or capital gains depending on how you classify the contract.

Example: You convert $5,000 worth of ETH (original cost basis: $2,000) to USDC. You've just realized a $3,000 capital gain. You then win $2,000 on a prediction market. That $2,000 is taxable income on top of the crypto gain. Your actual profit was $2,000, but your taxable events total $5,000 in transactions.

This is why the step-by-step guide to science and tech prediction market tax considerations recommends separating crypto wallets used for prediction markets from your regular crypto holdings — it makes cost basis tracking dramatically simpler.

Deductions and Offsets: Keeping More of What You Earn

Smart traders don't just track income — they track everything that can legally reduce their tax bill.

What You May Be Able to Deduct

If you qualify as a professional trader (meaning trading is your primary business activity), you can potentially deduct:

• Subscription fees for platforms like PredictEngine or data services
• Software and tools used for research and automation
• Home office expenses if you trade from a dedicated workspace
• Education costs directly related to trading strategy

If you're classified as a hobby trader or investor, your deductions are more limited — but you can still offset gains with losses within the same category.

Loss Harvesting for Prediction Markets

Just like stock traders harvest losses in December, prediction market traders can do the same. If you have unrealized losses on open contracts near year-end, consider closing them before December 31 to lock in the deduction for that tax year. Then re-enter similar (not identical — watch wash sale rules if they apply) positions in January.

For traders using smart hedging strategies with arbitrage, position exits for tax purposes can often be timed to coincide with natural hedge adjustments, minimizing disruption to your overall strategy.

Record Keeping: The Foundation of a Clean Tax Filing

The single biggest mistake prediction market traders make is poor record keeping. The IRS can audit up to 3 years back (or 6 years if they suspect substantial underreporting), so your records need to be organized and retained.

Minimum records to keep for every trade:

• Platform name and account ID
• Contract name and description
• Date opened and date closed
• Amount wagered / invested (in USD)
• Settlement amount (in USD)
• Crypto conversion amounts and fair market values (if applicable)
• Any fees paid

Use a dedicated spreadsheet or crypto/trading tax software like Koinly, TaxBit, or CoinTracker if you have crypto-settled trades. For pure USD platforms, a well-organized CSV export + spreadsheet is usually sufficient.

Frequently Asked Questions

Are prediction market winnings taxable in 2026?

Yes, prediction market winnings are taxable in the United States regardless of the platform or amount. The specific tax treatment depends on the platform's regulatory status, with regulated markets like Kalshi potentially qualifying for favorable Section 1256 treatment. You're required to report all winnings even if you don't receive a 1099 form.

Do I have to report small prediction market wins under $600?

Yes. The $600 threshold only determines when platforms are required to issue 1099 forms to you — it does not set a floor for what you must report. The IRS expects you to self-report all taxable income, including prediction market profits below $600, on your annual return.

What's the difference between Section 1256 treatment and gambling income for prediction markets?

Section 1256 treatment applies to qualifying regulated contracts and gives you a 60/40 long-term/short-term capital gains split, which typically lowers your effective tax rate. Gambling income is taxed at ordinary income rates, and losses can only be deducted if you itemize. Regulated CFTC markets like Kalshi have a stronger case for Section 1256; offshore or crypto-settled platforms typically don't qualify.

How do crypto-funded prediction markets affect my taxes?

Every time you convert cryptocurrency (like ETH or BTC) to fund a prediction market account, you trigger a taxable event based on the crypto's gain or loss since you acquired it. Your prediction market winnings are then taxed separately. This double-layer tax situation is why keeping a detailed cost basis record for all crypto used in prediction trading is essential.

Can I deduct prediction market losses?

Yes, but the rules depend on classification. Losses on Section 1256 contracts can offset other capital gains and may be carried back up to 3 years. Gambling losses can offset gambling winnings but only if you itemize deductions, and they cannot reduce other income. Professional traders may have more flexible loss treatment if their trading activity qualifies as a business.

Will prediction market platforms send me a 1099 in 2026?

Regulated US platforms like Kalshi are required to issue 1099-B forms for qualifying transactions above certain thresholds. Offshore or crypto-settled platforms typically do not issue 1099s, but that doesn't reduce your reporting obligation — the IRS still expects you to report the income. Always reconcile any 1099s you receive against your own records before filing.

Final Thoughts: Build Your Tax Strategy Before You Trade

The traders who come out ahead in prediction markets aren't just the best at picking outcomes — they're the ones who treat their trading operation like a real business, and that means taking taxes seriously from day one.

Start every calendar year with a clean record keeping system, know the regulatory status of every platform you use, and don't wait until March to figure out what you owe. If your annual prediction market volume exceeds $25,000 or you're trading on multiple platforms with crypto, working with a CPA who specializes in derivatives or crypto is almost always worth the cost.

Tools like PredictEngine are built for serious traders who want data-driven edges — and that same rigor should apply to how you manage the financial and tax side of your operation. Whether you're just scaling up as a new prediction trader or managing an established hedging portfolio, a solid tax playbook is as important as any trading strategy you deploy.
