Robinhood is backing a push to eliminate SEC Rule 611, the regulation that requires brokers to execute trades at the best available price. The effort, if successful, could reshape how retail orders are handled and open the door for blockchain-based trading systems. But critics warn it could undermine price protections for everyday investors.
What Rule 611 does
Rule 611 is the core of the SEC's order protection rule. It forces brokers to route orders to the venue offering the best price, regardless of where that venue is. For retail traders, that's meant to guarantee they get the best deal on a given stock or ETF. The rule has been a fixture of U.S. equities markets for decades.
The argument for scrapping it
Proponents say eliminating Rule 611 could lower trading costs. Without the obligation to hunt for the best price, brokers might execute trades faster or at a cheaper internal cost. The change could also open the door for innovation in blockchain-based equity markets — think decentralized exchanges that don't route through traditional venues. That's the argument Robinhood is lining up behind.
The risks for retail investors
Critics aren't buying it. They warn that removing Rule 611 could erode price fairness for retail investors. Without the requirement, a broker could fill an order at a worse price and pocket the difference. For the average trader, that might mean paying more for stocks without knowing it. The timing isn't great either — retail investors have been burned by opaque order routing before.
No formal SEC proposal has been filed yet. The push appears to be an early positioning move — testing the waters ahead of a possible rulemaking. Whether the regulator will take up the issue is the open question. For now, the debate sits at the intersection of market structure and crypto's ambitions to rewrite it.
