IB banning opening new put option positions in GME

Shit, I traded hundreds of GME puts today, if not thousands. Still have a lot of orders in but I guess play is over.
Though I don’t think MMs have anything to say in terms of IB and vice versa. MMs trade with exchanges, while all brokers simply submit orders to exchanges.
Unless the ban is at the exchange level.

I mean if I buy puts on IB and if a MM is on the other side of the trade & wants to hedge that short put, he will need to short the stock. If there is not enough stock out there accessible by MMs to short, then hence why the ban on opening new long puts (That's my assumption).

Puts are only set for closing, which in reality helps the rally. Once people close out their put positions, MMs will essentially cover i.e. buy.

The guys at IB are fueling the rally further or helping it.
 
I deleted that comment because I think That might not be correct.

It is indeed correct. The stock is standing rock solid above $300 (Now at $345 with 40 mins to close). 29-Jan expiry (next Friday) has some 300k puts OI and 150k calls OI. The fact that all those puts are out there means that a lot of them are actually hedged with short stock or at best with other long puts in farther expires.

With such a trajectory in the last 2 weeks and the stock is not collapsing, it only means one thing, it probably isn't over yet.
