Before you check
Are Polymarket and Kalshi winnings taxable?
For US taxpayers, yes. Income from all sources is taxable whether or not you receive a form. The open question is how it is taxed: as capital gains, Section 1256 contracts, other income or gambling. The IRS has not ruled on prediction-market contracts, which is why we calculate all four side by side instead of picking one.
Which tax treatment is correct for prediction markets?
There is no IRS ruling yet. OddsFile shows the estimated result of each treatment with the assumptions spelled out, so you and your tax professional can make the call with real numbers. We never recommend a treatment and we never file anything.
Does Kalshi send a 1099 for my trading gains?
Kalshi’s 1099s cover items like interest and rewards; the trading result appears on its annual Profit and Loss statement as a single FIFO net figure, not trade-by-trade cost basis. Our report rebuilds every fill and settlement, reconciles to that figure and keeps an audit trail if you are ever asked.
Will I get a Form 1099-DA for Polymarket or Hyperliquid?
Form 1099-DA reporting by US custodial brokers starts with 2025 digital-asset sales. On-chain activity from a self-custodied wallet usually is not reported by a broker, so the record-keeping is on you. Our exports are built from on-chain data and venue APIs, one row per disposal.
What is the difference between FIFO and HIFO?
They decide which lot a sale closes. FIFO sells your oldest shares first. HIFO sells the highest-cost shares first, which usually realizes the smallest gain. Switch between them in the report and every number, export and treatment updates. Use one method consistently and keep the records that support it.
