PFOF only applies to traditional markets when orders are matched by brokers to market makers without sending to a central exchange, right? But on prediction markets, Kalshi is the exchange AND the broker, so PFOF as a concept doesn't really apply?

Please correct me if I'm wrong @spiderduckpig, I don't have much first hand experience of US markets and PFOF.

@spiderduckpig also you might want to extend the market, it's about to expire.
