New York attorney general sues Coinbase, Gemini over ‘unlicensed gambling’

Grounds for suing Coinbase and Gemini’s prediction platform

The Attorney General urged Coinbase and Gemini to settle the penalty, waive illegal gains, and reimburse the alleged customers. Remarking on the matter, James further added, 

Besides the alleged illegal operations, James flagged flaws in the 18-21 age requirement, which exposed underage users to access such platforms.

The NYAG added, 

Additionally, the NYAG claimed that Coinbase and Gemini lacked licenses from the New York State Gaming Commission, suggesting this was done to avoid tax obligations, raising concerns about their operations in the state.

Coinbase fights back

However, Coinbase CLO Paul Grewal dismissed these allegations with claims to fight back and noted, 

Looking back, Coinbase and Gemini launched their betting platforms in response to the rise in popularity of prediction markets during the 2024 U.S. presidential election. In mid-December 2025, both launched ⁠their respective prediction markets, which now operate in all 50 U.S. states.

Now, as they face gambling allegations, competitor Polymarket has moved ahead by announcing plans for a native stablecoin.

Final Summary

• The New York Attorney General’s gambling allegations have put Coinbase and Gemini into the spotlight.
• Polymarket and Kalshi were also banned and ceased, back in 2022 and 2025, respectively, but things are normal now.
