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 region's treatment of USDC-denominated transactions. This overview covers essential regulations — always seek advice from a qualified tax adviser in your location before making decisions.
United States
- Access to most prediction market platforms is restricted for US-based participants (Polymarket applies geographic restrictions) — though on-chain participation remains technically available
- The IRS categorises crypto holdings as tangible property; each USDC transaction may trigger a taxable event
- Earnings from prediction markets are generally subject to short-term capital gains treatment (taxed at ordinary income rates for holdings under 12 months)
- Kalshi (operating under CFTC oversight) generates 1099 documentation; decentralised platforms do not — taxpayers must report independently
- Active traders may qualify for trader tax classification (permitting mark-to-market election)
United Kingdom
- Possible gambling exemption: returns may be exempt if the activity qualifies as gambling
- Investment classification triggers capital gains tax: £3,000 exemption threshold applies in 2026
- Income-generating trading activity may incur National Insurance obligations alongside income tax
- HMRC has not released authoritative guidance on how prediction markets should be classified
Germany
- §23 EStG: gains under €600 annually from private transactions are exempt
- USDC positions retained beyond 12 months: gains may be exempt under German Krypto-Steuerrecht rules
- Regular trading activity typically results in income tax liability
- Glücksspielgewinne (gambling-related returns) ordinarily escape taxation — though prediction market classification remains ambiguous
Australia
- The ATO categorises crypto as property: capital gains obligations arise on sale
- Assets retained for 12+ months qualify for a 50% capital gains discount
- Gambling-related returns are ordinarily untaxed unless the participant is classified as a professional gambler
Best Practices Globally
- Export your full transaction ledger from PolyGram for use in tax filings
- Employ dedicated crypto accounting platforms (Koinly, CoinTracking) to compute gains and losses
- Maintain comprehensive documentation of all USDC activity, including fiat conversion points
- Engage a tax specialist with crypto expertise relevant to your country
FAQ
- Does PolyGram submit my earnings data to revenue agencies?
- PolyGram presently does not produce tax documents for individual accounts. Self-reporting of prediction market returns remains your obligation under applicable law.
- Is USDC subject to different tax rules than other cryptocurrencies?
- Across most jurisdictions, USDC remains classified as a digital asset governed by identical tax principles as Bitcoin or Ethereum. Its price stability streamlines gain computation but does not alter underlying tax consequences.
- What documentation must I retain?
- Retain all transaction receipts containing timestamps, quantities, entry and exit valuations, and settlement details. PolyGram supplies downloadable transaction records — obtain copies on an ongoing basis.
