What changed (newest first)

Where Wisconsin sits in the national fight

Wisconsin is in the Seventh Circuit, which has not issued an appeals ruling on sports event contracts that we know of. Federal appeals courts elsewhere are split, all at the preliminary-injunction stage: the Third Circuit sided with Kalshi (April 6, 2026), the Ninth (August 28, 2026) and Sixth (September 25, 2026) sided with the states, and three Supreme Court petitions (Nos. 26-299, 26-338, 26-344) are pending; none has been granted. Read how the Supreme Court petitions work.

What Wisconsin Residents Can Trade

Users of these platforms in Wisconsin can trade on a diverse portfolio of real-world events. Contracts are typically structured as "Yes/No" questions, with prices ranging from 1¢ to 99¢, reflecting the market-perceived probability of an outcome. Common categories include:

  • Sports: Outcome of games (e.g., "Will the Green Bay Packers win their next game?"), player performance, championship winners.
  • Politics & Government: Election outcomes, passage of legislation, judicial appointments.
  • Economics & Finance: Federal Reserve interest rate decisions, inflation rates, GDP growth, cryptocurrency prices.
  • Weather & Climate: Hurricane landfalls, daily temperature records in major cities.
  • Science & Entertainment: Box office numbers, award show winners.

Tax and Compliance Considerations for WI Residents

Gains from trading on prediction markets are generally considered taxable income by the IRS↗ (opens in a new tab). While the specific tax treatment can be complex and may depend on your trading frequency and strategy (e.g., short-term vs. long-term capital gains, ordinary income), residents should assume all profits are subject to federal and Wisconsin state income tax.

Kalshi provides a downloadable profit-and-loss statement for your trades (its 1099s cover interest, rewards and crypto transfers). It is crucial for traders to maintain accurate records and consult with a tax professional in Wisconsin to ensure full compliance with all reporting requirements.

What could change the status

Dates we are watching: Nevada's responses to the Robinhood and Crypto.com Supreme Court petitions are now due November 13 and 16, 2026 (both extended in October), and Kalshi's response to New Jersey's petition is due November 9, 2026 (deadlines can be extended); the earliest the Supreme Court could act on the petitions is a conference in December 2026 or January 2027 (our estimate, not a scheduled date); Kalshi asked the full Sixth Circuit to rehear the case on October 9, 2026, and the court has not ruled; the CFTC's October 9, 2026 interim final rule takes effect only when it is published in the Federal Register, which had not happened as of October 14, 2026. We re-check this page when any of these happen and log the change above.
