Where are prediction markets legal?
Each venue is available or restricted state by state. These are the 22 states where at least one of Kalshi, Polymarket and Robinhood has a case, as of Oct 23, 2026 (Polymarket: Oct 21, 2026); every other state has no order, lawsuit or cease-and-desist we found.
Why there is more than one way to file
Federal appeals courts are split over whether these contracts are gambling that a state can license or exchange products that only the CFTC regulates. A ruling on state licensing is not a tax ruling, and the IRS has issued no guidance on event contracts. Because no court or agency has settled what these contracts are, people file them more than one way. Of the people we’ve seen file, these are the three most common ways, and Realize supports each of them. The same trades can be priced under each route, side by side.
| Route | Form | What it does |
|---|---|---|
| Gambling income, section 165(d) | Schedule 1; losses on Schedule A | Winnings are reported in full. Losses can be deducted only if you itemize, at 90% of losses and capped at winnings (tax years beginning after Dec 31, 2025). |
| Standard capital gains | Form 8949 and Schedule D | Each closed contract is a sale. Gain or loss is short or long term by holding period, and net losses can offset other gains. |
| Section 1256 | Form 6781 | 60% of the net gain or loss is treated as long term and 40% as short term. Open positions are marked to market at year end, and a net loss can be carried back three years. |

Appeals courts4 rulings
Prediction market appeals: what have the federal courts decided?
As of Oct 23, 2026 (Polymarket: Oct 21, 2026), the Third, Ninth and Sixth Circuits have ruled in these cases on whether sports event contracts are swaps and whether federal law preempts state gambling law, and their rulings point different ways. The Third Circuit’s ruling for Kalshi is a preliminary-injunction ruling: it held that Kalshi is likely to succeed, not that it has won. A ruling binds the federal courts in the states its circuit covers.
| Court | Case | Ruling | What it held | Source |
|---|---|---|---|---|
| Third CircuitApr 6, 2026 | Kalshi’s case | For Kalshi | Ruled for Kalshi: it is likely to succeed in showing that federal law preempts New Jersey's ban on its sports contracts. | Opinion |
| Ninth CircuitAug 28, 2026 | Kalshi’s case | For the states | Ruled for Nevada: sports contracts likely aren't swaps, so states can enforce. Kalshi has asked the full court to rehear the case. | Opinion |
| Ninth CircuitAug 28, 2026 | Robinhood’s case | For the states | In an unpublished memorandum (No. 25-7831), affirmed the denial of Robinhood's request for a temporary restraining order in Nevada, concluding that sports-related contracts are not swaps under the Commodity Exchange Act and following its published Kalshi opinion (No. 25-7516) filed the same day. Robinhood has petitioned the Supreme Court. | Opinion |
| Sixth CircuitSep 25, 2026 | Kalshi’s case | For the states | Ruled for Ohio and Tennessee: Kalshi hasn't shown its sports contracts are swaps, and even if they were, federal commodities law doesn't preempt the states' gambling laws. Kalshi asked the full court to rehear on Oct 9, 2026. | Opinion |

Supreme Court3 petitions
Can a state block a CFTC-regulated prediction market?
Unresolved as of Oct 23, 2026 (Polymarket: Oct 21, 2026). Three petitions ask the Supreme Court whether federal commodities law preempts state gambling law, and none has been granted. Meanwhile, the state orders and agreements listed below have switched some markets off.
Who gets to regulate sports contracts on a federally registered exchange: only the federal regulator, or the states too? The Court is being asked whether federal commodities law preempts state gambling laws, not whether anyone must stop, and not how the trades are taxed.
- No. 26-299Filed Sep 2, 2026Flaherty v. KalshiEXNew Jersey (state gaming regulators). From the Third Circuit, No. 25-1922, which ruled for Kalshi on Apr 6, 2026.Kalshi's response is due Nov 9, 2026, extended at Kalshi's request from Oct 8.

Questions6 questions
Questions people ask.
Short answers, from the status files as of Oct 23, 2026 (Polymarket: Oct 21, 2026).
Where are prediction markets switched off?
As of Oct 23, 2026 (Polymarket: Oct 21, 2026): Robinhood in Michigan (sports stopped by agreement since Sep 9, 2026); Kalshi in Washington (switched off since Sep 2, 2026); Kalshi in Michigan (switched off since Jun 29, 2026); Kalshi in Nevada (switched off since Mar 20, 2026); Polymarket in Nevada (switched off since Jan 29, 2026); Robinhood in Nevada (sports stopped by agreement since Dec 1, 2025). In the other 19 states listed here, a case or letter is live and nothing is switched off.
Which states have sued prediction market companies?
As of Oct 23, 2026 (Polymarket: Oct 21, 2026), officials or a city in 11 states have sued at least one of Kalshi, Polymarket and Robinhood: Connecticut, Kentucky, Maryland, Massachusetts, Michigan, Nevada, New Mexico, New York, Rhode Island, Washington and Wisconsin.
What have the federal appeals courts decided?
The Third Circuit, in Kalshi’s case on Apr 6, 2026: Ruled for Kalshi: it is likely to succeed in showing that federal law preempts New Jersey's ban on its sports contracts. The Ninth Circuit, in Kalshi’s case on Aug 28, 2026: Ruled for Nevada: sports contracts likely aren't swaps, so states can enforce. Kalshi has asked the full court to rehear the case. The Ninth Circuit, in Robinhood’s case on Aug 28, 2026: In an unpublished memorandum (No. 25-7831), affirmed the denial of Robinhood's request for a temporary restraining order in Nevada, concluding that sports-related contracts are not swaps under the Commodity Exchange Act and following its published Kalshi opinion (No. 25-7516) filed the same day. Robinhood has petitioned the Supreme Court. The Sixth Circuit, in Kalshi’s case on Sep 25, 2026: Ruled for Ohio and Tennessee: Kalshi hasn't shown its sports contracts are swaps, and even if they were, federal commodities law doesn't preempt the states' gambling laws. Kalshi asked the full court to rehear on Oct 9, 2026.
Has the Supreme Court taken a prediction market case?
Not as of Oct 23, 2026 (Polymarket: Oct 21, 2026). Three petitions ask it to: No. 26-299, Flaherty v. KalshiEX; No. 26-338, Robinhood Derivatives v. Dreitzer; No. 26-344, North American Derivatives Exchange v. Nevada. The next date on the docket is Nov 9, 2026: Kalshi's response to New Jersey's petition is due.
Does a state ruling change how prediction market trades are taxed?
Courts are split on whether these contracts are state gambling or CFTC-regulated exchange products. A licensing ruling is not a tax ruling, and the IRS has issued no guidance on event contracts. That open question is why people file three common ways; Realize supports each.
