# Wisconsin Attorney General Prediction Market Enforcement
|
|
|
|
**Type:** State enforcement action
|
|
**Jurisdiction:** Wisconsin
|
|
**Filed:** April 25, 2026
|
|
**Lead:** Attorney General Josh Kaul
|
|
|
|
## Overview
|
|
|
|
Wisconsin Attorney General Josh Kaul filed a lawsuit against five major prediction market platforms on April 25, 2026, alleging they operate as illegal gambling operations by offering "disguised sports betting through 'event contracts'" without state gambling licenses.
|
|
|
|
## Defendants
|
|
|
|
- Kalshi
|
|
- Polymarket
|
|
- Robinhood
|
|
- Coinbase
|
|
- Crypto.com
|
|
|
|
## Legal Theory
|
|
|
|
**Core allegations:**
|
|
- Platforms circumventing gaming regulations by relabeling sports bets as prediction markets
|
|
- Collecting fees "for every bet that's made" without state gambling license
|
|
- Operating in violation of Wisconsin state gambling regulations
|
|
|
|
**Relief sought:**
|
|
- Court declaration that sports-related event contracts are illegal under Wisconsin law
|
|
- Shutdown of unauthorized betting operations in Wisconsin
|
|
|
|
## Tribal Gaming Context
|
|
|
|
The Oneida Nation participated in the enforcement action, emphasizing that licensed tribal gaming operators face strict oversight (audits, consumer protections, state compact requirements) while prediction market platforms operate without equivalent requirements, creating unfair competitive advantage.
|
|
|
|
Governor Tony Evers recently signed legislation legalizing online sports betting exclusively through tribal compacts in Wisconsin. Implementation is still under negotiation, but the compact structure gives tribal nations exclusive rights to online sports betting in the state.
|
|
|
|
## Coordination Pattern
|
|
|
|
Filed one day after 38 state attorneys general filed an amicus brief in the Massachusetts Supreme Judicial Court prediction market case (April 24, 2026), demonstrating coordinated timing and messaging across multiple state enforcement actions.
