**Ken Griffin became closely associated with Situational Awareness in July 2026 after Citadel purchased most of the hedge fund's public equity portfolio.** Situational Awareness LP, founded by former OpenAI researcher **[Leopold Aschenbrenner]()**, had grown into one of the fastest-growing AI-focused hedge funds, managing more than **$20 billion in assets**.

## Ken Griffin and GameStop \| Citadel’s Role in the Meme Stock Saga Explained
**Ken Griffin became a central figure during the 2021 GameStop short squeeze because of his connections to Citadel LLC and Citadel Securities.** Citadel Securities acted as a market maker that executed trades for retail brokerages, including Robinhood, while **Citadel LLC**, Griffin’s hedge fund, operated as a separate investment business. At the same time, **Citadel LLC invested approximately $2 billion in Melvin Capital** alongside Point72 after the hedge fund suffered heavy losses from its short position in GameStop. Griffin later testified before the **U.S. House Committee on Financial Services**, stating that Citadel Securities had **no role in Robinhood’s decision to restrict GameStop trading**.
**The GameStop controversy brought intense public attention to Griffin and Citadel.** Many retail investors questioned the relationships between Citadel, Robinhood, and Melvin Capital after trading restrictions took effect during the meme stock rally.

**Today, the GameStop episode remains one of the defining moments of Ken Griffin’s career.** The event sparked lasting debates about **short selling, payment for order flow, market transparency, and retail investor access**.
