I wonder if this ban for market makers will affect Robinhood. SEC Chairman Gary Gensler said that a full ban of payment for order flow is “on the table.” Payment for order flow is a practice where brokers send trade orders to market makers that execute those trades in return for a portion of the profits Gensler says the practice has “an inherent conflict of interest.” Market makers make a small spread on each trade, but that’s not all they get, he said “They get the data, they get the first look, they get to match off buyers and sellers out of that order flow,” he said. “That may not be the most efficient markets for the 2020s.”
