Citadel Securities has reported a record trading revenue of $9.7 billion for the year 2024, marking a 55% increase compared to the previous year. This achievement positions Citadel among the largest trading firms globally, surpassing some of Europe's major banks, including Barclays and Deutsche Bank. The firm’s revenue growth is attributed to its role in executing trades for platforms like Robinhood, which has been under scrutiny for regulatory violations. In related news, Robinhood has agreed to pay $29.75 million to settle claims from the Financial Industry Regulatory Authority (FINRA) regarding various violations, including supervisory failures and issues related to the trading of GameStop and AMC stocks. This settlement follows a separate $45 million agreement with the U.S. Securities and Exchange Commission earlier this year. Robinhood's Gold subscription service is reportedly generating $15.5 million in monthly recurring revenue, and the company is preparing for its second annual Gold event on March 26, 2025.
