Context
Robinhood, once considered a symbol of speculation on the stock market, now meets the requirements for inclusion in the S&P 500 - the company demonstrates stable profits and has reached key thresholds for market capitalization and liquidity, Bloomberg writes. Inclusion in the index means that the securities of the retail app will now end up in the portfolios of pension and index funds around the world.
Robinhood IPOed in 2021 - in the midst of a pandemic boom in meme stocks, the agency recalls. Thanks to its user-friendly mobile app, the broker became a favorite tool for retail traders to transact in high-risk assets like GameStop and AMC. In the first quarter of 2025, Robinhood reported a 77% year-over-year growth in transaction revenue - mainly driven by cryptocurrencies.
AppLovin, a developer of an ad promotion app, also IPO'd in 2021. AppLovin has become one of the most notable stocks on the market, with its stock price rising 278% in 2023 and more than 700% in 2024. By the close of trading on Friday, the company's securities had posted a 51% gain since the start of 2025.
AppLovin is in the business of integrating targeted advertising into mobile apps and games, giving advertisers access to a wide audience via smartphones. Earlier this year, AppLovin even offered to buy out the US segment of TikTok from China's ByteDance.
