FINRA's new PDT rule (effective June 4, 2026) removes the $25K minimum equity requirement, replacing it with intraday margin standards. This lowers barriers for small-account active traders and could increase engagement with retail brokers like Robinhood, which benefits from higher trading activity through options, equities, and margin revenue. Key risks include phase-in delays through Oct 2027, uncertain adoption rates by brokers, and regulatory uncertainty around how the new framework will actually be enforced.

Post argues Robinhood will inevitably succeed as a financial platform due to its user-friendly interface, growing market share, and expanding product offerings. Key risks include regulatory challenges, competition from established brokers, and dependence on retail trading volume.
