Citadel slashes Micron stake by 87% despite chip stock's 671% surge

Ken Griffin's Citadel Advisors has slashed its stake in Micron Technology by 87%, reducing its position from roughly 4.6 million shares to 600,523 shares over the last three months. The move comes even as Micron shares surged 671% over the past year amid the AI memory boom. The reduction was not isolated. Citadel also cut its Taiwan Semiconductor Manufacturing stake by 87%, trimming roughly 3.5 million shares, and reduced STMicroelectronics holdings by 44%. The hedge fund made broad cuts across sectors, including General Electric (down 72%), Citigroup (down 63%), and Tesla (down 41%). This suggests Citadel may have been reducing overall risk rather than making a bearish call on semiconductors specifically. Micron's fiscal third quarter 2026 revenue reached $41.5 billion, up 346% year over year.

Hedge fund giant Citadel is looking to buy US shale oil production assets, sources say.

Hedge fund giant Citadel is looking to buy US shale oil production assets, sources say. September 4, 2026 at 12:04 PM GMT+0 * Citadel is exploring acquisitions of U.S. shale oil production assets, according to sources familiar with the matter. * The move would extend the firm's push into physical energy after its 2025 purchase of Paloma Natural Gas, now rebranded as Apex Natural Gas. * Citadel's interest underscores a broader trend of trading houses and financial firms seeking direct control of energy supply. A strategic shift. Citadel, the $71 billion hedge fund run by Ken Griffin, is looking to buy U.S. shale oil production assets, according to people familiar with the matter. The potential acquisitions would mark a significant expansion of Citadel's energy footprint, which has primarily focused on natural gas through its Apex Natural Gas unit. The firm entered upstream production in 2025 with the acquisition of Paloma Natural Gas for around $1 billion, giving it a foothold in the Haynesville shale, a major gas-producing region. Since then, Apex has been on an acquisition spree, agreeing in December to buy Texas natural-gas assets from Comstock Resources (CRK) for about $430 million and separately acquiring Haynesville assets from Azul Resources (AZUL). Apex is now operating about 14 rigs, up sharply from its initial footprint. While Citadel's focus so far has been on gas, the new interest in oil assets signals a potential pivot. "They see opportunities in the oil patch that align with their trading strengths," said one industry source, who asked not to be named because the discussions are private. Citadel declined to comment. The move comes as shale oil producers face pressure from lower crude prices, which have made some drilling uneconomical. This has created buying opportunities for well-capitalized buyers like Citadel, which can leverage its trading platform to hedge and market production. The broader context. Citadel's expansion reflects a growing trend of financial and trading firms moving into physical energy assets. Gunvor, for example, has been in talks to buy Silver Hill Energy Partners' Haynesville gas assets for an estimated $1.2 billion-$1.5 billion. Vitol has also invested in U.S. gas-producing and export-linked facilities. The Haynesville basin has become particularly valuable due to its proximity to Gulf Coast LNG terminals, where exports are booming. "The basin's appeal is tied to LNG expansion and AI-driven power demand," noted an energy analyst. This has made it a hotspot for M&A, with Comstock recently agreeing to sell minority stakes to Azerbaijan's SOCAR (403550.KS) for $1.65 billion. For Citadel, owning physical assets offers more than just a bet on energy prices. It provides supply assurance, valuable information about regional flows, and the ability to optimize marketing and transport. This vertical integration is a central motive behind the strategy. What's next? A deal is not assured merely because sources report discussions. If Citadel proceeds, it would likely face regulatory scrutiny, though such acquisitions are generally approved. The company would also need to manage the operational risks of oil production, which differ from gas. In the medium term, more M&A is expected as producers seek capital and position for future demand. Citadel's entry could encourage other financial firms to follow suit, potentially reshaping the landscape of U.S. shale ownership. For now, investors and competitors will be watching to see if Citadel converts its interest into action. As one banker put it, "When Citadel moves, it moves big."

Santander and Citadel plan over 1.5M SF of Brickell office towers to fill Miami's supply gap

Two major office towers in Miami's Brickell district could deliver over 1.5 million square feet of leasable space by the early 2030s, addressing a critical shortage of large office blocks. Santander broke ground in April 2026 on a 50-storey tower at 1401 Brickell Avenue, spanning over 1 million square feet with 560,000 square feet of marketable offices. The project is expected to complete by summer 2029. Citadel is planning a $2.5 billion waterfront tower along Brickell Bay Drive, totalling 1.7 million square feet. The firm will occupy approximately 560,000 square feet, leaving roughly 1 million square feet available for other tenants. Vertical construction could begin in Q4 2026. Brickell's Class A direct vacancy stood at 11.8% in Q2 2026, with average asking rents reaching $93.03 per square foot. Trophy office rents have climbed to $250 per square foot.

Chris Foster leaves Citadel after $2B gas crisis trading profits.

Chris Foster leaves Citadel after $2B gas crisis trading profits. 2026-09-03 11:43:26 Chris Foster, the senior portfolio manager whose London-based team generated approximately $2 billion in trading profits during Europe's energy crisis, is leaving Ken Griffin's Citadel. Foster's aggressive positioning in European natural gas markets during 2022, when Russia's invasion of Ukraine sent energy prices into convulsions, helped Citadel surpass Bridgewater Associates to become the most profitable hedge fund of all time. His departure comes as European natural gas markets have normalized from the panic-driven extremes of 2022, with prices stabilized and the continent having diversified supply sources away from Russian pipeline gas. Foster's team generated $2 billion from 2022 gas crisis. Foster's team accounted for approximately $2 billion of the roughly $8 billion in total profits that Citadel's commodities division generated in 2022. The $8 billion haul was instrumental in pushing Citadel past Bridgewater Associates to become the most profitable hedge fund of all time, a title Ray Dalio's firm had held for years. When Russia curtailed natural gas flows to Europe, prices whipsawed violently. Foster's team, operating out of Citadel's London office, was positioned to capitalize on those moves. Returns across Citadel's commodities business started to come back to earth in 2023 and into 2024 and 2025. Citadel acquired Paloma assets for $1 billion in March 2025. In March 2025, Citadel completed the acquisition of Paloma Natural Gas assets in the Haynesville Shale for approximately $1 billion. The acquired assets were subsequently rebranded as Apex Natural Gas, giving Citadel a direct foothold in US natural gas production. Foster donated £25 million to Oxford college before exit. Foster made headlines by donating £25 million to Mansfield College at Oxford University, his alma mater. The gift was reported as the largest single donation in the college's roughly 200-year history. Faq. What profits did Chris Foster's team generate at Citadel during the 2022 energy crisis? Chris Foster's team generated approximately $2 billion in trading profits during 2022, which accounted for a significant portion of Citadel's commodities division's total $8 billion profit that year. The team capitalized on volatile European natural gas markets when Russia curtailed gas flows to Europe following its invasion of Ukraine. What natural gas assets did Citadel acquire in March 2025? In March 2025, Citadel completed the acquisition of Paloma Natural Gas assets in the Haynesville Shale for approximately $1 billion. The acquired assets were rebranded as Apex Natural Gas, providing Citadel with direct ownership in US natural gas production operations.

Citadel demands Marshall Wace executives hand over messages in Dan Shatz recruitment dispute

Citadel is seeking court orders to compel two senior Marshall Wace executives to provide communications regarding the recruitment of Dan Shatz, a former Citadel credit portfolio manager. Shatz joined Marshall Wace as global head of credit in late 2024. Citadel alleges that Marshall Wace partner Anthony Clarke and co-portfolio manager Alan Hofmeyr were heavily involved in recruiting Shatz and met him in London during his noncompete period. The firm claims Marshall Wace has produced limited communications since a June court order. The dispute stems from an arbitration battle between Shatz and Citadel, where he worked until summer 2023. Shatz claims he is owed a "significant eight-figure" amount after raising internal concerns about potential securities violations. Citadel alleges Shatz violated his noncompete agreement. Marshall Wace declined to comment.
