Taxation of prediction market earnings differs substantially across jurisdictions and hinges on variables such as trading volume, whether it constitutes your primary source of income, and your country's stance on USDC-denominated transactions. This overview covers the essential regulatory landscape — always engage a qualified tax adviser in your region for personalised guidance.
United States
- Access to most prediction market venues is restricted for US residents (Polymarket implements geographic restrictions) — though blockchain-based activity remains theoretically reachable
- The IRS classifies digital assets as property; every USDC transaction may trigger a taxable event
- Earnings from prediction markets are likely taxed as short-term capital gains (taxed at ordinary income rates if positions are closed within 12 months)
- Kalshi (CFTC-authorised) generates 1099 documentation; decentralised platforms do not — traders must report independently
- Active traders may qualify for trader status (permitting mark-to-market election)
United Kingdom
- Possible gambling exemption: winnings may escape taxation if the activity qualifies as gambling
- Investment classification results in capital gains tax: £3,000 exemption threshold applies in 2026
- Income-generating trading activity is taxed as earned income — National Insurance contributions may be due
- HMRC guidance on prediction markets remains non-definitive
Germany
- §23 EStG: gains below €600 annually from private transactions are exempt
- USDC holdings exceeding one year: potential exemption under German cryptocurrency tax law
- Active trading typically results in ordinary income tax liability
- Glücksspielgewinne (gambling proceeds) ordinarily escape taxation — though prediction market classification remains ambiguous
Australia
- The ATO categorises digital assets as property; capital gains tax applies upon realisation
- 50% reduction in capital gains tax for holdings exceeding 12 months
- Gambling proceeds are ordinarily untaxed unless the participant is a professional gambler
Best Practices Globally
- Export your full transaction record from PolyGram for use in tax filings
- Employ dedicated crypto accounting tools (Koinly, CoinTracking) to determine gains and losses
- Maintain comprehensive documentation of every USDC movement, including conversions to and from fiat
- Retain a tax specialist with expertise in digital assets within your country
FAQ
- Does PolyGram report my earnings to tax authorities?
- PolyGram presently does not furnish tax documentation to participants. You bear full responsibility for disclosing prediction market income according to your local rules.
- Is USDC treated differently from volatile crypto for tax?
- Across most jurisdictions, USDC remains subject to identical tax rules as Bitcoin or Ethereum. Its price stability makes gain computation more straightforward but does not alter the underlying tax classification.
- What records should I keep?
- Retain all transaction receipts showing timestamp, quantity, entry and exit prices, and settlement outcome. PolyGram supplies downloadable transaction records — retrieve them on a regular schedule.
