In November 2020, his net worth surpassed $20 billion according to "Bloomberg News" due to an increase in returns and valuation from Citadel and Citadel Securities. The increase was largely due to Citadel's sister firm Citadel Securities doubling their profit to $2.36 billion during the first half of the 2020 compared to $982 million for the same period the year before. The increase in revenue was due to increased volatility, volume and retail trader engagement. As of November 2020 his 85% stake in Citadel Securities is worth an estimated $11.2 billion according to "Bloomberg News".
