### Billionaire Ken Griffin of Citadel Backs Palantir and Broadcom, Reduces Nvidia Stake

Billionaire investor Ken Griffin of Citadel is making significant moves in the artificial intelligence (AI) sector, as revealed by the recent quarterly Form 13F filings. Griffin’s hedge fund has boosted its investments in Palantir Technologies and Broadcom, while notably downsizing its stake in Nvidia. These filings, mandatory for institutional investors managing at least $100 million, provide insight into the latest buying and selling activities of top Wall Street money managers.

During the quarter ending in June, Citadel increased its positions in Palantir Technologies by a staggering 1,140% and in Broadcom by 64%. Palantir, a leader in AI-driven data-mining, operates through two core segments: Gotham and Foundry. Gotham aids federal governments in data collection and mission planning, while Foundry helps businesses streamline operations using AI and machine learning. Broadcom, renowned for its AI networking solutions, has developed the Jericho3-AI fabric, capable of connecting up to 32,000 GPUs to maximize their computing potential.

Despite this aggressive buying in Palantir and Broadcom, Citadel drastically cut its holdings in Nvidia by 79%. Nvidia, which has added over $3 trillion to its market capitalization since the start of 2023, leads the market in AI-GPUs, accounting for 98% of GPUs shipped to data centers in the past two years. However, Citadel’s reduction in Nvidia shares signals caution due to historical trends of tech bubbles and increasing competition from companies like Advanced Micro Devices and internal developments by Nvidia's largest customers.

Palantir and Broadcom’s dual reliance on AI and other robust business segments perhaps contributes to Griffin’s confidence in their stability. Palantir’s services for government and business data integration provide a safeguard against any potential AI market fluctuations. Similarly, Broadcom’s diversification into wireless chips, optical components, and cybersecurity solutions adds layers of security beyond its AI products.

Nvidia’s lack of recent insider stock purchases and the looming threat from competitors appear to justify Citadel's decision to pare down its investment. As AI technology continues to evolve, Griffin’s strategic repositioning underscores the volatility and rapid changes characterizing this sector. While Nvidia remains a formidable force, the data suggests its valuation needs to be carefully monitored amidst burgeoning competition and the unpredictable trajectory of AI developments.
