How prediction market earnings are taxed depends heavily on your location and personal circumstances—including how frequently you trade, whether this constitutes your main source of revenue, and the way your country treats USDC-denominated activity. This overview covers the essential tax frameworks across major jurisdictions. For your own situation, always seek guidance from a qualified accountant familiar with your region's rules.
United States
- Most prediction market platforms restrict access to American residents (Polymarket implements geographic blocking) — though blockchain-based trading remains technically available
- The IRS classifies cryptocurrency holdings as property; every USDC transaction may trigger a taxable event
- Earnings from prediction markets are generally treated as short-term capital gains (taxed at ordinary income rates when held fewer than 12 months)
- Kalshi, being CFTC-regulated, generates 1099 reporting forms; decentralised platforms do not — meaning you must declare your own income
- Those engaged in active trading may potentially claim trader tax status, allowing mark-to-market accounting treatment
United Kingdom
- Potential gambling exemption: winnings might escape taxation if the activity qualifies as gambling under HMRC rules
- If treated as an investment: the £3,000 capital gains tax allowance applies annually in 2026
- Income classification for professional traders — National Insurance contributions may be due
- HMRC guidance on prediction markets remains non-specific and lacks clarity
Germany
- §23 EStG provisions: gains below €600 annually from private asset sales escape taxation
- USDC positions retained beyond one year may qualify for exemption under German cryptocurrency tax law
- Regular trading activity typically results in ordinary income tax assessment
- Glücksspielgewinne (gaming profits) ordinarily face no tax — though how prediction markets fit this category remains ambiguous
Australia
- The ATO views cryptocurrency as property: capital gains tax applies when you sell or dispose
- A 50% reduction in capital gains tax applies to assets held longer than 12 months
- Gambling profits are typically not taxable unless you operate as a professional gambler
Best Practices Globally
- Export your full transaction log from PolyGram to support your tax filings
- Employ dedicated crypto tax platforms (Koinly, CoinTracking) to compute your gains and losses automatically
- Maintain comprehensive documentation covering every USDC movement, including deposits and withdrawals
- Engage a tax specialist with expertise in cryptocurrency matters within your country
FAQ
- Does PolyGram report my earnings to tax authorities?
- PolyGram presently does not furnish tax documentation to members. You bear sole responsibility for declaring your prediction market income according to your local tax requirements.
- Is USDC treated differently from volatile crypto for tax?
- Across most jurisdictions, USDC remains classified as a cryptocurrency asset and faces identical tax rules as Bitcoin or Ethereum. Its price stability makes gain computation simpler but does not alter the underlying tax framework.
- What records should I keep?
- Retain all transaction receipts showing date, quantity, entry and exit prices, and settlement details. PolyGram allows you to download your transaction history — save copies on a regular basis.
