Prediction Market Tax Guide 2026: Country-by-Country Overview

The tax implications of prediction market earnings differ substantially across jurisdictions and hinge on variables such as trading volume, whether this represents your primary source of income, and how your tax authority interprets USDC-denominated transactions. This overview covers the essential regulatory framework — always engage a qualified tax advisor in your region for personalised guidance.

United States

• Access to most prediction market services is restricted for US-based participants (Polymarket implements geographic restrictions) — though direct blockchain participation remains technically possible
• The IRS classifies digital assets as property; every USDC transaction may constitute a reportable taxable event
• Earnings from prediction markets are ordinarily categorised as short-term capital gains (taxed at ordinary income rates for positions held under 12 months)
• Kalshi (operating under CFTC oversight) generates 1099 documentation; decentralised platforms do not — participants must self-report all transactions
• Active traders may potentially qualify for trader tax status, enabling mark-to-market accounting treatment

United Kingdom

• A gambling exemption may apply: earnings could be entirely exempt from taxation if classified as gambling activity
• Investment classification triggers capital gains tax: the £3.000 annual exemption threshold applies in 2026
• Income derived from professional trading activity is subject to income taxation — National Insurance contributions may also be due
• HMRC guidance remains inconclusive regarding the precise tax status of prediction market transactions

Germany

• Under §23 EStG: gains from private asset disposals below €600 annually are exempt from taxation
• USDC holdings retained for more than one year: resulting gains may qualify for tax exemption under German cryptocurrency tax law
• High-frequency trading activity typically results in ordinary income tax classification
• Glücksspielgewinne (gambling-derived winnings) ordinarily escape taxation — though the regulatory classification remains ambiguous

Australia

• The ATO characterises digital assets as property: capital gains taxation applies upon sale or exchange
• Assets retained for a minimum of 12 months qualify for a 50% capital gains tax discount
• Gambling-derived income is customarily non-taxable unless the participant qualifies as a professional gambler

Best Practices Globally

• Export your transaction ledger from PolyGram to facilitate accurate tax computation
• Leverage specialised crypto accounting platforms (Koinly, CoinTracking) for precise gain/loss determination
• Maintain comprehensive documentation of every USDC transaction, encompassing initial purchase and final liquidation
• Retain a tax specialist with expertise in cryptocurrency and blockchain-based assets in your country

FAQ

Does PolyGram report my earnings to tax authorities?

PolyGram presently does not furnish tax reporting documents to participants. Individual users bear full responsibility for disclosing prediction market earnings to their respective tax jurisdictions.

Is USDC treated differently from volatile crypto for tax?

Across most tax regimes, USDC remains classified as a digital asset subject to identical rules as Bitcoin or Ethereum. Although its price stability streamlines gain computation, the underlying tax framework remains unchanged.

What records should I keep?

Retain all transaction receipts documenting the execution date, quantity, entry and exit prices, and final outcome. PolyGram supplies downloadable transaction records — retrieve these on a recurring basis.
