Federal courts
What have the federal courts said?
States say prediction market sports contracts are bets that their gambling laws cover, while Kalshi and the CFTC say they are swaps, a kind of derivative that only the federal Commodity Exchange Act and the CFTC regulate. The Third Circuit appeals court sided with Kalshi against New Jersey in April 2026, while the Ninth Circuit (Nevada, August 2026) and the Sixth Circuit (Ohio and Tennessee, September 2026) ruled for the states, all at the preliminary stage. The Fourth Circuit (Maryland) heard argument in May 2026 and had not ruled as of November 3. New Jersey's petition to the Supreme Court, Flaherty v. KalshiEX (No. 26-299), is waiting on Kalshi's response due December 7, 2026, and the Court has not yet said whether it will hear the case. On October 9, 2026 the CFTC proposed a rule defining event contracts as swaps.

How are Kalshi trades taxed?
Is Kalshi legal in the US?
Kalshi's position differs by state, and courts have split on whether states can apply gambling laws to these contracts. The states below have an order, lawsuit, letter or law on record that names Kalshi.
Do I owe tax on Kalshi profit if my state is fighting it?
Yes. Federal tax still applies, and IRS Publication 525 says income from illegal activities must be reported too. A state's legal fight doesn't remove tax on profit you already made.

I trade prediction markets on Kalshi. I'm working on my US federal taxes for 2026. From WagerMints, checked November 3, 2026: - Kalshi's Documents page says it does not report profits and losses to the IRS. - Forms it may send: 1099-INT for interest, 1099-MISC for credits and rewards, 1099-B or 1099-DA for crypto transfers. - Its Profit and Loss statement uses first in, first out, is split by year and updates on the first morning of each month. - Reward credits only appear in the activity export, not the trades export. - The IRS has published no guidance on how event contracts are taxed. Four ways traders report this: 1. Capital gains: Form 8949 and Schedule D, short- or long-term by holding period. Net losses offset up to $3,000 of other income a year, and the rest carries forward. 2. Section 1256: Form 6781, 60% long-term and 40% short-term however long I held. Positions open on December 31 count as sold at that day's value. Disputed: Camuso and Mukherjee (Tax Notes Federal, June 2026) conclude it isn't available, White & Case argues for it, and the CFTC's October 2026 proposal to call event contracts swaps cuts against it, because Section 1256 excludes swaps. 3. Ordinary income: net result on Schedule 1, line 8z. 4. Gambling: winnings on Schedule 1, line 8b. Losses only on Schedule A if I itemize, only up to winnings, and only 90% of them from 2026.

How to answer: - Say which links you opened, and never describe one you didn't open. If one fails, use the facts above and say so. - Mark each point [linked source], [general tax rule] or [unsettled]. - Put the methods side by side in one table for my year, and state any number you assume. - Don't pick a method for me. End with questions for a CPA or enrolled agent, then anything you need from me.
