Robinhood’s stock fell on Monday after the brokerage app received news that there might be a possible ban on paying for order flow.

SEC Chairman, Gary Gensler said in an interview with Barron’s on Monday that a complete ban on paying for order flow is “on the table.”

As a result, Robinhood’s shares dropped 6.9% to $43.64 per share.
