The taxation of prediction market earnings differs substantially across jurisdictions and hinges on elements such as trading volume, whether trading constitutes your primary occupation, and your country's regulatory stance on crypto-based transactions like USDC settlements. This overview covers the principal tax frameworks — always engage a qualified tax adviser in your region for personalised guidance.
United States
- Access to most prediction market platforms is restricted for US-based participants (Polymarket implements geographic restrictions) — though decentralised on-chain alternatives remain technically available
- The IRS classifies crypto holdings as tangible property; each USDC transaction may constitute a reportable taxable event
- Earnings from prediction markets are generally taxed as short-term capital gains (at standard income tax rates for positions held under 12 months)
- Kalshi, which operates under CFTC oversight, generates 1099 documentation; decentralised platforms do not — participants must self-declare
- Active traders may be eligible for trader tax status classification (permitting mark-to-market methodology)
United Kingdom
- Potential gambling exemption: returns may escape taxation if the activity qualifies as gambling under UK law
- Capital gains classification applies a £3,000 annual exemption threshold for the 2026 tax year
- Activities deemed professional trading incur income tax obligations — National Insurance contributions may also be due
- HMRC has not yet issued binding clarification on how prediction markets should be categorised for tax purposes
Germany
- Under §23 EStG, private transaction gains not exceeding €600 annually are exempt from taxation
- USDC holdings maintained beyond 12 months may qualify for tax exemption under German cryptocurrency law
- Regular or intensive trading activity typically results in ordinary income tax classification
- Glücksspielgewinne (gaming winnings) ordinarily carry no tax burden — though applicability to prediction markets remains ambiguous
Australia
- The ATO classifies crypto as property; capital gains tax applies when positions are closed
- Assets retained for 12 months or longer qualify for a 50% capital gains tax discount
- Gaming winnings are typically non-taxable unless the participant is classified as a professional gambler
Best Practices Globally
- Export your full transaction ledger from PolyGram to support tax documentation
- Leverage automated tax calculation platforms (Koinly, CoinTracking) to determine realised gains and losses
- Maintain comprehensive records covering all USDC movements, including entry and exit transactions
- Retain a tax professional with expertise in cryptocurrency and digital asset treatment
FAQ
- Does PolyGram report my earnings to tax authorities?
- PolyGram does not presently furnish tax documentation to participants. Responsibility for declaring prediction market income rests entirely with the individual in their respective jurisdiction.
- Is USDC treated differently from volatile crypto for tax?
- Across most jurisdictions, USDC remains classified as a crypto asset subject to identical taxation rules as BTC or ETH. Although its price stability reduces computational complexity in gain determination, the underlying tax regime remains unchanged.
- What records should I keep?
- Retain all transaction receipts documenting the date, quantity, entry price, exit price, and settlement outcome. PolyGram supplies downloadable trade records — maintain regular exports for your records.
