Crypto Legal Roundup: Polymarket, Tornado Cash, and Celsius Cases Update
Key crypto legal battles involving Polymarket, Tornado Cash, and Celsius are shaping up for 2026 courtroom action.

The outcome could carry significant weight for how courts treat executive accountability in crypto firm failures that wiped out billions in customer funds. No ruling on that motion has been issued yet.
Taken together, these cases illustrate how crypto enforcement is maturing from regulatory skirmishes into full-scale federal litigation with multiyear timelines. Continue reading at Cointelegraph.
