The taxation of earnings from prediction markets differs substantially across jurisdictions and hinges on several variables: your trading volume, whether this constitutes your primary occupation, and your country's approach to USDC-denominated transactions. This overview covers the principal tax considerations — you should always seek guidance from a qualified tax adviser familiar with your local rules.
United States
- Most prediction market platforms restrict access for US-based users (Polymarket implements geographic blocking) — though direct blockchain engagement remains technically available
- The IRS classifies crypto holdings as property; each USDC transaction may trigger a taxable recognition event
- Winnings from prediction markets are ordinarily taxed as short-term capital gains (at ordinary income rates if positions are closed within 12 months)
- Kalshi, operating under CFTC oversight, generates 1099 reporting forms; decentralised platforms do not — meaning traders must independently report their income
- Active traders may potentially qualify for trader tax status, which permits mark-to-market election
United Kingdom
- A potential gambling exemption exists: winnings may escape taxation if the activity qualifies as gambling under HMRC rules
- If treated as investment activity: a £3,000 annual capital gains tax exemption applies in 2026
- Activities classified as professional trading are subject to income tax — National Insurance contributions may also be due
- HMRC has not yet issued authoritative guidance on how prediction markets should be classified for tax purposes
Germany
- Under §23 EStG: gains from private asset disposals below €600 annually are exempt from taxation
- Holding USDC for more than one year: gains may qualify for exemption under German cryptocurrency tax law
- Regular or high-frequency trading typically results in ordinary income tax classification
- Glücksspielgewinne (gambling-related winnings) ordinarily escape taxation — though the classification of prediction market activity remains uncertain
Australia
- The ATO regards crypto as a capital asset: capital gains taxation applies upon realisation
- A 50% capital gains tax concession is available for assets retained beyond 12 months
- Gambling-related winnings are ordinarily not taxable unless the participant is classified as a professional gambler
Best Practices Globally
- Export your full transaction log from PolyGram to support your tax filing
- Leverage specialist crypto accounting platforms (Koinly, CoinTracking) to determine your precise gains and losses
- Maintain comprehensive documentation of all USDC transactions, including deposits and withdrawals
- Engage a tax professional with expertise in cryptocurrency matters within your country
FAQ
- Does PolyGram report my earnings to tax authorities?
- PolyGram does not presently furnish tax documentation to participants. You bear sole responsibility for declaring your prediction market income according to your country's requirements.
- Is USDC treated differently from volatile crypto for tax?
- Across most jurisdictions, USDC remains a cryptocurrency asset governed by identical tax rules as Bitcoin or Ethereum. Although its price stability makes gain computation more straightforward, the underlying tax classification remains unchanged.
- What records should I keep?
- Retain all transaction confirmations showing the date, quantity, entry and exit prices, and settlement outcome. PolyGram allows you to download your transaction history — ensure you retrieve this regularly for your records.
