Citadel LLC + Citadel Securities — the unambiguous apex winner of the GME event
The PFOF chokepoint. Citadel Securities controls ~40% of US retail equity order flow via payment-for-order-flow. Q1 2021 during the GME extreme volatility: Robinhood generated $331 million in PFOF revenue, of which $142 million came directly from Citadel Securities. The retail order flow Robinhood aggregated routed to Griffin's market maker — the apex counterparty to every 'rebellious' retail trade.
The Melvin $2 billion injection — 3 days before the halt. Jan 25 2021: Citadel LLC (hedge fund) injected $2 billion into collapsing Melvin Capital alongside Point72's $750 million.
The Sequoia spiderweb. January 2022: Citadel Securities received $1.15 billion investment from Sequoia Capital + Paradigm at $22 billion valuation. Sequoia is also a pre-IPO backer of Robinhood (which monetized via $32 billion July 2021 IPO) and holds overlapping LP positioning with major hedge funds nominally 'defeated' in January 2021. At the cap-table layer, the 'retail vs hedge fund' binary collapses into a single VC-backed ecosystem.
Political Consolidation. Griffin is among the largest individual donors to US Republican / libertarian political infrastructure.
