SEC kills PDT rule, and broker stocks get giddy

Bye-bye, $25k handcuffs

The SEC just took a sledgehammer to one of retail trading’s oldest annoyances: the pattern day trader rule. That means smaller accounts may no longer have to sit on their hands after a few trades, and that’s music to the ears of app-based brokerages like Webull and Robinhood.

For these platforms, more freedom for users usually means more clicks, more trades, and more opportunities to monetize the chaos. If you’re a brokerage built on engagement, this is the kind of rule change that can turn a slow Tuesday into a very busy one.

Prediction markets: the shiny new toy

Then there’s the other catalyst making investors swoon: prediction markets. Bernstein’s Gautam Chhugani said volumes could hit about $240 billion in 2026 and climb to $1 trillion by 2030, which is a pretty bold way of saying this space might go from niche internet gamble to serious business.

If regulators stay friendly, prediction markets could become another high-margin product for retail platforms that already live and die by trading activity. That’s why the rally wasn’t just about one rule change — it was about the possibility of a whole new revenue lane opening up.

The takeaway

Webull, Robinhood, Interactive Brokers, and Schwab all stand to benefit if retail trading gets easier and speculative products get broader acceptance. The near-term boost comes from more active trading; the longer-term upside comes from a bigger menu of things to trade.

Big picture: when the rules loosen and the toys multiply, brokerages usually find a way to make money — and investors love that story.
