Robinhood Markets Surges 14% on August 21 for Best Single-Day Gain Since September 2025

Robinhood Markets shares jumped 14% on Friday, August 21, making it the top performer in the S&P 500 for the session and the stock's best single-day gain since September 2025. The rally was fueled by a broader surge in crypto-linked equities as Bitcoin prices rose, with Robinhood climbing alongside Coinbase, up 8.89%, and Marathon Digital, up 9.64%, reflecting higher trading volumes across retail crypto and equity markets. Robinhood had already gained nearly 5% in pre-market trading before extending those gains through the session.

The stock's advance helped lift the Nasdaq to a positive close on what was also August monthly options expiration day, a session shaped by roughly 25 million SPX contracts of open interest with the 7,650 SPX level serving as a key gamma concentration point. Despite Friday's strong performance, Robinhood remains down approximately 7.8% year to date.
