The tax implications of prediction market earnings differ substantially across jurisdictions and hinge on variables such as trading volume, whether this constitutes your primary occupation, and how your region treats USDC-denominated transactions. This overview covers the essentials — always engage a qualified tax adviser within your own territory for personalised guidance.
United States
- Many prediction market platforms restrict access for US-based participants (Polymarket implements geographic filtering) — though blockchain-based activity remains technically available
- The IRS classifies digital assets as property; each USDC transaction may trigger a taxable event
- Earnings from prediction markets are ordinarily subject to short-term capital gains tax (taxed at ordinary income rates if positions are closed within 12 months)
- Kalshi (operating under CFTC oversight) generates 1099 forms; decentralised platforms do not — individuals must self-declare
- Traders with sufficient volume and intent may qualify for trader tax status, enabling mark-to-market treatment
United Kingdom
- A gambling exemption may apply: returns could be non-taxable if the activity qualifies as gambling
- Investment classification results in capital gains tax: a £3,000 annual exemption threshold exists for 2026
- Income-generating trading activity is taxed as earnings — National Insurance contributions may be due
- HMRC has not issued comprehensive guidance on how prediction markets should be categorised
Germany
- §23 EStG permits tax-free treatment of private transaction gains below €600 annually
- USDC held for longer than 12 months may qualify for exemption under German cryptocurrency tax law
- Regular, active trading typically falls under income tax rather than capital gains
- Glücksspielgewinne (gambling-related returns) ordinarily escape taxation — though regulatory classification remains ambiguous
Australia
- The ATO views digital assets as property: capital gains tax applies upon sale or exchange
- A 50% discount on capital gains applies to assets retained for 12 months or more
- Gambling-related returns are typically not subject to tax, provided the individual is not classified as a professional gambler
Best Practices Globally
- Export your full transaction ledger from PolyGram to support tax filings
- Leverage crypto tax calculators (Koinly, CoinTracking) to determine your gain or loss positions
- Maintain comprehensive documentation of every USDC movement, including deposit and withdrawal events
- Engage a tax specialist with cryptocurrency expertise relevant to your country
FAQ
- Does PolyGram report my earnings to tax authorities?
- PolyGram presently does not furnish tax documentation to participants. You bear sole responsibility for declaring prediction market income according to your local tax rules.
- Is USDC treated differently from volatile crypto for tax?
- Across most jurisdictions, USDC remains a digital asset subject to identical taxation as Bitcoin or Ethereum. Its price stability reduces the complexity of calculating gains but does not alter the fundamental tax framework.
- What records should I keep?
- Retain documentation of every transaction including timestamp, quantity, entry and exit prices, and settlement outcome. PolyGram allows you to download your transaction history — save copies on a regular basis.
