Citadel Investments, the hedge fund owned by billionaire Ken Griffin, is facing its worst annual return since 2018 after a failed bet on natural gas, a major source of its profits. According to a source familiar with the matter, the flagship fund had a return of 9.3% as of December 18. The fund profited across equities, fixed income, credit, and quantitative strategies, and even made a small profit on commodities, including natural gas, after suffering losses at the beginning of the year. Even so, with less than two weeks left in the year, it could become Citadel Investments' sixth year with a return below 10% since its inception in 1990, highlighting the company's reliance on commodity trading in recent years, which has fueled its high returns. Ken Griffin has previously stated that Bitcoin will be disrupted by a more advanced cryptocurrency based on the Ethereum blockchain, but ultimately, the digital dollar will disrupt the entire cryptocurrency space, and the only way to value cryptocurrencies is to hope that someone will buy them at a higher price in the future.
