A Kalshi prediction market display in New York

Here's the lowdown

  • Prediction market profits are taxable, but a trade that looks like an investment is not automatically a capital gain.

  • Gambling, capital-asset and Section 1256 contract rules handle gains, losses and reporting in very different ways.

  • Clients should save every trade, settlement, fee and tax form instead of waiting until filing season to rebuild the record.

A simple contract creates a hard tax question

Prediction markets make uncertainty look tidy. Buy a contract for 40 cents. Collect $1 if the event happens. Walk away with a 60-cent profit.

Then tax season arrives and the clean little trade gets messy.

The contract may feel like a stock because it has a market price and can be sold. It may feel like a bet because the payoff depends on a game, election or other event. Some contracts also trade on federally regulated exchanges.

Those labels are not interchangeable on a tax return. The right answer depends on what the contract legally is, how the platform operates and which tax rule applies to that product.

The capital-gain answer is not automatic

Investors often assume that a trade on a financial-looking app belongs on the capital-gains schedule. That is the dangerous shortcut.

If a prediction contract is treated as a capital asset, its holding period matters. The IRS capital-gains rules generally treat an asset held for one year or less as short term. A net short-term gain is taxed at ordinary income rates.

Long-term gains can receive lower rates, but many event contracts settle in days or months. They may never get close to a one-year holding period.

Capital treatment also changes the loss math. Capital losses first offset capital gains. If losses are larger, most individuals can deduct only up to $3,000 of the remaining net loss against other income for the year and carry the rest forward.

That can produce a surprise when a client has many winning and losing contracts but little net cash profit.

Gambling rules create a different mismatch

If a contract is treated as gambling, the reporting path changes.

The IRS gambling guidance says gambling winnings are fully taxable. A casual gambler must report the winnings even when the payer does not send a Form W-2G.

Losses do not simply erase winnings everywhere on the return. A casual gambler generally must itemize deductions, keep records and claim losses only up to the amount of gambling income reported.

That is why someone can feel close to break-even while the return still looks lopsided. Gross wins may appear as income, while the loss benefit depends on a separate deduction and the taxpayer's facts.

The record rule is strict for a reason. The IRS tells gamblers to keep a diary or similar log plus receipts, tickets, statements or other proof showing wins and losses.

Regulated contracts add a third possibility

Some traders point to federal market regulation and assume that every prediction contract receives futures-style tax treatment. That shortcut is risky too.

The IRS uses Form 6781 for gains and losses from qualifying Section 1256 contracts. Those contracts follow mark-to-market rules, which treat positions as sold at fair market value at year-end.

But a platform's regulator, marketing language or trading screen does not settle the tax classification by itself. The specific contract still has to fit the tax law's definition.

That is the core problem: three familiar tax systems sit nearby, but the public IRS pages do not place every prediction-market product into one universal bucket.

The platform tax form is evidence, not the whole answer

A client may receive a tax form from the platform, or nothing at all. Neither outcome makes the profit disappear.

The form can show how the platform reported the activity. It does not replace a review of the contracts, trading statements and applicable rules.

Tax advisers do not all reach the same answer today. Some view short-lived event contracts as producing ordinary income. Others see capital or regulated-contract arguments for particular products. That disagreement is a warning against one blanket rule for every app and market.

Build the file before the return

Clients should download their full transaction history while it is still easy to get. The file should show each contract, purchase price, sale or settlement amount, dates, fees and withdrawals.

They should also separate open positions from settled positions and save any Form 1099, W-2G or other tax document the platform provides.

For advisers, the first question is not, "How much did you win?" It is, "What exactly did you buy?"

Bottom line: prediction markets made event betting look like trading. Tax law has not made the classification look nearly as simple. Keep the evidence, review the actual contract and do not choose the friendliest tax label after the result is known.
