Thursday marks the first day that the Pattern Day Trader rule no longer applies to accounts under $25,000 — the most significant change to retail trading access in a generation, and a potential windfall for three publicly traded brokerages.

PDT Rule Eliminated 

The U.S. Securities and Exchange Commission (SEC) approved FINRA’s elimination of the PDT designation and its $25,000 minimum equity requirement on April 14, with the new intraday risk-based margin framework taking effect Thursday, June 4. 

For 25 years, any margin account holder who executed four or more day trades in a rolling five-business-day period was flagged as a pattern day trader and locked out unless they maintained a $25,000 floor. That rule is now gone.

Robinhood

Robinhood Markets, Inc. (NASDAQ:HOOD) came into the day with more fanfare than any broker. 

The company posted a countdown clock on X, and its official account announced: “June 4: The PDT rule will be eliminated, and the $25,000 minimum account balance requirement will officially end. We will be wiping all past PDT flags clean. Soon, customers will be able to trade on Robinhood without worrying about day trading limits again.” 

Robinhood followed-up with a celebratory X post Thursday morning that read: "Robinhood has lifted PDT restrictions. No more $25K minimum, no more flags. Happy trading." 

Robinhood boasts 27.4 million funded customers and $623 million in Q1 transaction-based revenue — plus a $17 billion margin book. Its core user base of small-account active traders is exactly who this rule change was built for.

The company, at last check, is trading at $85.35 and up 3% with a market cap of $77.2 billion.

Webull

Webull Corp. (NASDAQ:BULL), at $6.06 and up 2.88 % with a market cap of $3.2 billion, may have the most direct operating exposure. The company confirmed day-one implementation and U.S. CEO Anthony Denier has been vocal for weeks. 

“Eliminating the $25,000 PDT threshold removes an arbitrary wealth barrier that has penalized smaller accounts for decades,” Denier said in a prior statement. 

On Webull’s Q1 earnings call, he added that he expects at least a 20% increase in transaction volume over time, and flagged a separate opportunity: account consolidation. 

“It is quite common for active smaller AUM clients to have multiple brokerage accounts,” Denier said. “The removal of the PDT and being a first mover is really significant for us to do a consolidation of a lot of those client assets.” 

Webull’s average account size is just under $5,000, meaning the majority of its user base was directly constrained by the old rule.

Interactive Brokers

Interactive Brokers Group (NASDAQ:IBKR), at $84.33, is the lone decliner of the three. The stock price is down 3.24% with a $145 billion market cap.

The firm confirmed it was “ready for the removal of the $25,000 PDT requirement and corresponding intraday margin rules, and will implement the changes on June 4 for eligible securities clients.” 

Interactive Broker’s clientele skews wealthier and more institutional, meaning fewer of its users were directly blocked by the $25,000 floor.

Still, a broader surge in retail trading activity broadly benefits the firm’s volumes and margin book.

Brokerages have until October 20, 2027, to fully phase in the new intraday margin framework. Therefore, the impact will be staggered across platforms and quarters. 

But Thursday marks the start of the clock — and all three stocks are watching the same tape.
