Taxation of earnings from prediction markets differs substantially across jurisdictions and hinges on elements such as trading volume, whether this represents your primary occupation, and your country's stance on USDC-denominated activity. This overview covers the principal considerations — always seek guidance from a qualified tax adviser in your region before making decisions.
United States
- Many prediction market platforms restrict access for US residents (Polymarket implements geographic restrictions) — though blockchain-based trading remains technically available
- The IRS categorises crypto holdings as property; each USDC transaction may trigger a taxable event
- Gains from prediction markets are likely classified as short-term capital gains (taxed at ordinary income rates if positions closed within 12 months)
- Kalshi (operating under CFTC oversight) generates 1099 forms; decentralised platforms do not — individuals must report independently
- Active market participants may qualify for trader tax status (permitting mark-to-market election)
United Kingdom
- Possible gambling exemption: winnings may be exempt from tax if the activity qualifies as gambling
- Investment classification triggers capital gains tax: £3,000 exemption threshold applies in 2026
- Trading undertaken as a profession is treated as income — National Insurance contributions may be due
- HMRC has not issued authoritative guidance on how prediction markets should be classified
Germany
- §23 EStG: gains from private asset disposals below €600 annually are exempt
- Holding USDC beyond 12 months: gains may be exempt under German cryptocurrency tax rules
- Active trading is likely classified as income-generating activity
- Glücksspielgewinne (gambling prizes) are ordinarily tax-exempt — though the classification of prediction markets remains ambiguous
Australia
- The ATO treats crypto as tangible property: capital gains tax applies upon sale
- Assets retained for 12 months or longer qualify for a 50% CGT reduction
- Gambling winnings are ordinarily not taxed unless the individual is classified as a professional gambler
Best Practices Globally
- Export your full transaction log from PolyGram for use in tax compliance
- Leverage dedicated crypto accounting tools (Koinly, CoinTracking) to compute profit and loss positions
- Maintain comprehensive documentation of every USDC movement, 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 prediction market income according to your local tax rules.
- Is USDC treated differently from volatile crypto for tax?
- Across most jurisdictions, USDC remains classified as a digital asset and faces identical tax treatment as BTC or ETH. Although its price stability makes gain computation simpler, the underlying tax framework remains unchanged.
- What records should I keep?
- Retain all transaction confirmations showing timestamps, quantities, entry and exit prices, and settlement outcomes. PolyGram supplies downloadable transaction records — ensure you retrieve these on a regular basis.
