Crypto Gambling & Sweepstakes: 2026 Tax Rules

Crypto gambling has exploded in popularity over the past few years. Online casinos, sports betting platforms, prediction markets, and sweepstakes contests now accept (and pay out in) Bitcoin, Ethereum, and stablecoins. The tax rules, however, have not kept pace with the technology. Whether you won big on Stake.com, cashed out a Polymarket position, or received a crypto sweepstakes prize, the IRS expects you to report every dollar of it.

This guide covers the 2026 tax rules for crypto gambling winnings, loss deductions, prediction markets, offshore reporting requirements, and more. For a broader overview of crypto taxation, see our complete crypto tax guide for 2026.

How Crypto Gambling Winnings Are Taxed

The IRS treats gambling winnings as ordinary income under IRC Section 61. This applies equally whether you are paid in dollars, Bitcoin, or any other cryptocurrency. The taxable amount is the fair market value (FMV) of the crypto at the moment you receive it.

Here is the key distinction: crypto gambling creates two taxable events, not one.

1. The gambling win itself. The FMV of the crypto you receive is ordinary income. Report it on Schedule 1, Line 8b (Other Income).
2. Later disposal of the crypto. When you sell, trade, or spend the winnings, you recognize a capital gain or loss based on the difference between your cost basis (the FMV at receipt) and the sale price.

Example: A Winning Bet

The same logic applies to sweepstakes prizes, giveaway winnings, and any other form of gambling payout received in crypto. For more on how crypto income is taxed generally, see our guide on crypto income from staking, mining, and airdrops.

W-2G Thresholds and Reporting

Traditional casinos and licensed U.S. gambling platforms issue Form W-2G when winnings exceed certain thresholds. The key thresholds for 2026 are:

Important: Even if no W-2G is issued, the income is still taxable. Many crypto-native platforms (both domestic and offshore) do not issue W-2Gs at all. The absence of a tax form does not mean the absence of a tax obligation.

Deducting Crypto Gambling Losses

You can deduct gambling losses, but the rules are strict:

• Itemizers only. You must itemize deductions on Schedule A. If you take the standard deduction, you cannot claim gambling losses.
• Capped at winnings. Losses are deductible only up to the total amount of gambling winnings you report. You cannot use gambling losses to offset wages, investment income, or other earnings.
• Documentation required. You need a detailed log of every session: dates, amounts wagered, amounts won or lost, the platform used, and the type of wager.

Example: Wins and Losses in the Same Year

Over the course of 2025, you have the following results across various crypto casinos:

• Total winnings: $12,000
• Total losses: $18,000

You report $12,000 in gambling income on Schedule 1. If you itemize, you can deduct up to $12,000 of losses on Schedule A. The remaining $6,000 in losses is not deductible and cannot be carried forward to future years.

Prediction Markets: Polymarket, Kalshi, and Others

Prediction markets have grown rapidly, with platforms like Polymarket and Kalshi allowing users to bet on real-world outcomes (elections, economic data, sports). The tax treatment of prediction market payouts is an evolving area.

The IRS has not issued formal guidance on whether prediction market winnings are classified as gambling income, capital gains, or something else. Here is what we know:

• Kalshi is a CFTC-regulated exchange. Some tax professionals argue that Kalshi contracts should be treated as Section 1256 contracts (60/40 long-term/short-term capital gains). However, the IRS has not confirmed this treatment.
• Polymarket operates offshore and uses crypto for settlement. Most practitioners treat Polymarket payouts as gambling income (ordinary income) until the IRS says otherwise.

Our recommendation: Treat prediction market winnings as gambling income on Schedule 1, Line 8b. This is the most conservative approach and protects you if the IRS later classifies these payouts as ordinary income. If you have significant prediction market activity, schedule a consultation to discuss your specific situation.

Until the IRS issues specific guidance on prediction markets, the safest approach is to treat all payouts as gambling income. Being conservative now avoids penalties later.

Offshore Crypto Casinos and Reporting Obligations

A large share of crypto gambling happens on offshore platforms: Stake.com, BC.Game, Roobet, Rollbit, and dozens of others. These platforms typically do not collect Social Security numbers, do not issue W-2Gs, and do not report to the IRS.

None of that changes your obligation. All gambling income is taxable regardless of the platform’s location or reporting practices.

Beyond income taxes, offshore crypto gambling can trigger additional reporting requirements:

FBAR (FinCEN Form 114)

If you held crypto in an offshore casino account and the aggregate value of all your foreign financial accounts exceeded $10,000 at any point during the year, you must file an FBAR. This form is filed separately from your tax return through the BSA E-Filing System. The deadline is April 15, with an automatic extension to October 15.

Penalties for failing to file an FBAR are severe: up to $10,000 per violation for non-willful failures, and up to $100,000 or 50% of the account balance (whichever is greater) for willful violations. Criminal penalties are also possible.

Form 8938 (FATCA)

If your foreign financial assets exceed certain thresholds ($50,000 for single filers, $100,000 for married filing jointly at year-end), you may also need to file Form 8938 with your tax return. For a detailed breakdown of these requirements, see our guide on FBAR and Form 8938 for crypto.

Professional Gamblers and Schedule C

If gambling is your primary source of income and you engage in it regularly with the intent to profit, you may qualify as a professional gambler under the IRS definition. Professional gamblers report income and expenses on Schedule C rather than Schedule 1 and Schedule A.

The advantages of professional gambler status include:

• Business expense deductions. You can deduct travel, software subscriptions, internet costs, and other expenses related to your gambling activity.
• Losses offset all income. Unlike recreational gamblers, professional gamblers can deduct losses against their full income (not just winnings).
• Net operating losses. If your losses exceed your total income, you may be able to carry the loss forward.

The downside is that Schedule C income is subject to self-employment tax (15.3% on the first $168,600 of net earnings for 2026). This is a significant additional cost that does not apply to recreational gamblers.

Qualifying as a professional gambler requires meeting a high bar. The IRS looks at factors like the time spent, consistency of activity, whether you maintain business-like records, and whether you depend on the income for your livelihood. Casual bettors who have a day job will almost certainly not qualify.

Record-Keeping Best Practices

The single most important thing you can do to protect yourself is maintain detailed records. For every gambling session, document:

• Date and time of the session
• Platform used (name and URL)
• Type of wager (slots, sports bet, poker, prediction market)
• Amount wagered (in crypto and USD equivalent)
• Amount won or lost (in crypto and USD equivalent)
• Transaction hashes for on-chain deposits and withdrawals
• Screenshots of bet confirmations and account balances

Sweepstakes and Giveaway Prizes

Crypto sweepstakes and promotional giveaways follow the same rules as gambling winnings. If you receive crypto as a prize (from a social media contest, exchange promotion, or sweepstakes entry), the FMV at the time of receipt is ordinary income.

The platform running the sweepstakes may issue a Form 1099-MISC for prizes valued at $600 or more. As with W-2Gs, the absence of a form does not eliminate your reporting obligation. If you won $200 in BTC from a Twitter giveaway, that $200 is taxable income.

Lost or Stolen Crypto from Gambling Platforms

If an offshore casino exit-scammed or you lost crypto due to a platform hack, you may wonder whether you can claim a tax deduction. Unfortunately, the Tax Cuts and Jobs Act (TCJA) suspended personal casualty and theft loss deductions through 2025. For 2026, these rules remain largely unchanged unless Congress acts. For more on this topic, see our article on lost and stolen crypto tax deductions.

Bottom Line: What to Do Next

Crypto gambling is taxable. Every win, every sweepstakes payout, every prediction market cash-out counts as income. The IRS does not care whether the platform issued a form or operates offshore. Your responsibility is to report accurately and keep detailed records.

Here is a quick action checklist:

1. Report all winnings on Schedule 1, Line 8b as ordinary income.
2. Track your losses in a detailed log if you plan to itemize deductions.
3. Check FBAR thresholds if you used any offshore gambling platform.
4. Export your transaction history from every platform before year-end.
5. Consult a specialist if you have complex activity across multiple platforms.
