Billionaire Ken Griffin Just Increased His Position in This Artificial Intelligence (AI) Stock by Over 1,600% (Hint: It's Not Nvidia)

Ken Griffin's Citadel Advisors significantly increased its stake in Microsoft (MSFT) by 1,636% in Q2, valuing the position at nearly $985 million, marking its most aggressive AI-related buy. This substantial investment, alongside similar moves by other prominent hedge funds like Millennium Management and Tiger Global, signals strong institutional conviction in Microsoft's AI-driven growth trajectory. The company's robust financial performance, including $281.7 billion in revenue and $101.8 billion in profits with 15-16% year-over-year growth, is largely attributed to its strategic integration of OpenAI's GPT-5 and its leading position in the booming cloud market via Azure.

Analysis

Ken Griffin's Citadel Advisors significantly increased its Microsoft (MSFT) stake by 1,636% in Q2, valuing the position at approximately $985 million and marking it as the firm's most aggressive AI-related buy. This substantial investment, alongside increased positions in Nvidia (414%) and Amazon (158%), highlights strong institutional conviction in key AI beneficiaries, despite Griffin's cautious public commentary on AI's broader market impact. Other major hedge funds, including Millennium Management and Tiger Global, also bolstered their Microsoft holdings in the same quarter. Microsoft's financial performance supports this investor confidence, with the company reporting $281.7 billion in revenue (+15% YoY) and $101.8 billion in profits (+16% YoY) for its latest fiscal year ending June 30, 2025. This robust growth is largely fueled by a massive AI tailwind, driven by the strategic integration of OpenAI's GPT-5 across its product lineup and its leading position in the cloud market via Azure, which is capitalizing on the deployment of generative AI applications. Despite a valuation exceeding 33 times forward earnings, the premium is justified by Microsoft's sustained growth and strategic diversification in AI partnerships, including Anthropic's Claude LLMs. Citadel's hedging strategy, involving both call and put options, indicates a sophisticated approach to managing risk while maintaining significant exposure to potential upside. Wall Street analysts largely concur, with 57 out of 58 rating MSFT a buy or strong buy, projecting an average 12-month upside of approximately 21%.
