We'll Help You Maximize Your Prediction Market Profits
Polymarket, Kalshi, PredictIt, and on-chain prediction venues are taxed as a moving target across provinces and states. We do prediction market tax planning, reconciliation, and reporting all year long, so when filing season comes, there are no surprises.
We'll help you simplify your prediction market tax challenges.
Tracking hundreds of contract resolutions across Polymarket, Kalshi, and PredictIt is the part most accountants quietly hand back to you. We don't.
- ×Contract classification complexity — binary contracts, scalar markets, and on-chain resolutions each have different income vs. capital gains treatment.
- ×Wagering vs. investment confusion — the IRS may treat your activity as gambling, hobby, or trader status — and the CRA tests are different again.
- ×Inaccurate reconciliation between centralized venue statements, on-chain wallets, and USDC deposits/withdrawals.
- ×Unclaimed losses on losing contracts that most filers leave on the table.
Clean books. Verified gains. Zero scramble at year-end.

Questions you may have about our prediction market tax accounting.
How are prediction market winnings taxed in Canada vs the US?
Canada often treats prediction market activity as business income (100%) or capital gains (50% inclusion) depending on intent and frequency. The US splits between Section 1256 (Kalshi), ordinary income, and gambling rules. We handle both.
What about on-chain markets like Polymarket?
Every USDC deposit, contract buy/sell, and resolution is a potentially taxable event. We classify each one — income vs. capital, ordinary vs. business — and reconcile it against the on-chain record.
Do you work with both Kalshi and Polymarket traders?
Yes. Kalshi issues a 1099-B and falls under CFTC rules. Polymarket is on-chain and unregulated in the US — the tax treatment is very different and we handle each correctly.
Can you defend a CRA or IRS audit?
Yes. Every engagement produces an audit-ready record with reconciled wallet data, cost basis rationale, and on-chain proofs. Our crypto lawyer leads defense if needed.
What does it cost to work with you?
Pricing depends on annual trade volume and venue coverage. Most clients land between a flat annual fee for filing-only and a monthly retainer for ongoing strategy. We'll quote during the strategy call.
We're one of the few firms that understand prediction markets from a tax accounting perspective.
