Frequently Asked Questions
Do I have to pay taxes on Polymarket profits?
In most countries, yes. In the US, prediction market profits are taxable as gambling winnings or capital gains. Some countries like the UK and Canada may not tax casual gambling winnings. Always check your local laws.
How does the IRS treat Polymarket?
The IRS hasn't issued specific guidance on prediction markets. Most tax professionals treat it as either gambling (Form 1040 Schedule 1) or short-term capital gains (Form 8949). Wins and losses are netted annually.
Can I deduct my Polymarket losses?
In the US, gambling losses can be deducted but only up to the amount of your winnings. You cannot use gambling losses to reduce other income. Keep detailed records to support deductions.
Is withdrawing USDC a taxable event?
Moving USDC isn't taxable. However, converting USDC to USD (or other currencies) may trigger a taxable event if USDC's value changed since you acquired it. In practice, USDC is usually 1:1 with USD.
What records should I keep?
Keep records of all deposits, withdrawals, trade confirmations, and market resolutions. Screenshot your trade history regularly. This documentation is essential if audited.
Do I need to report small profits?
Technically, yes. In the US, all income is taxable regardless of amount. However, enforcement focus is typically on larger amounts. Always consult a tax professional.
