#纽约与polymarket互诉预测市场合法性
New York and Polymarket countersue each other, with a positive clash over regulation of prediction markets
The timeline of the lawsuit on September 24 is actually very clear.
Step one: during the daytime on September 24, New York State Attorney General Letitia James formally filed a lawsuit against Polymarket, asking the court to restrict it from conducting related business in New York and to seek back relevant proceeds and penalties. New York argues that Polymarket’s event contracts are subject to New York’s applicable laws.
Step two: later that same evening, Polymarket turned around and sued New York State Attorney General James and other state officials in the federal court in Manhattan, seeking to stop New York from regulating its prediction markets. In other words, this is not one-sided oversight—both sides entered litigation on the same day to confront each other.
So what’s truly worth paying attention to in this countersuit isn’t just whether Polymarket can continue operating in New York. It’s that both sides are fighting over a bigger question: what regulatory framework should govern prediction markets and event contracts.
New York’s core position is that this kind of contract constitutes a business that must be regulated under state law; Polymarket, meanwhile, is trying to use the lawsuit to prevent New York from regulating it.
The logic of transmission is also straightforward: New York sues → regulatory uncertainty increases → Polymarket countersues → both sides enter the judicial process → other states and similar platforms pay attention → compliance expectations across the prediction market industry are repriced.
But there’s another possibility too. If the court ultimately clarifies the regulatory boundaries for event contracts, it could actually give the entire industry clearer rules.
In my view, what truly matters this time isn’t who wins first, but how the court ultimately defines event contracts—and whether that definition will affect other prediction market platforms.
For near-term focus, watch three key nodes: whether the court takes limiting measures, whether other jurisdictions follow suit, and how subsequent rulings define the regulatory boundaries.
On September 24, New York filed first, Polymarket then countered, and both sides officially pushed the regulation issue for prediction markets into the judicial arena.
