Does billionaire Ken Griffin know something Wall Street doesn't? The Citadel Chief Sold More Than 80% of His Broadcom Stock and Is Switching to Another Artificial Intelligence (AI) Stock-Split Stock Instead

    • Ken Griffin's fund, Citadel, is a “pod shop” in which the firm allocates capital to mini-teams that have wide autonomy over what they invest in.

    • In the second quarter, Citadel dumped most of its position in custom artificial intelligence chipmaker Broadcom.

    • The company jumped into one of the most prominent AI stocks on the market.

    One of the richest people in the world, Ken Griffin, has an estimated net worth of over $50 billion, according to Forbes, thanks to his career in finance. The Harvard graduate founded Citadel in 1990 and has grown the company into one of the largest hedge funds in the world and a major market maker.

    Even though the company owns thousands of shares, investors are always curious about what the “smart money” on Wall Street is up to. In the second quarter of the year, Citadel dumped most of its stake in the custom chipmaker Broadcom (NASDAQ:AVGO) and instead switched to another popular artificial intelligence (AI) stock.

    The “Magnificent Seven” have become household stocks because of their massive technology holdings, market caps of more than $1 trillion, and because investors expect them to be the big winners from the artificial intelligence boom. Broadcom was not part of the Magnificent Seven, but has recently emerged as a comparable company. The stock price is up about 91% in the past year and now has a market cap of about $1.63 trillion.

    Broadcom makes custom chips for AI workloads that include hyperscalers like OpenAI, AlphabetAnd Metaplatforms have taken a great interest in it. While Nvidia (NASDAQ: NVDA) is the premier pick-and-shovel play for AI, creating graphics processing units that can perform multiple tasks at once, Broadcom focuses on application-specific integrated circuits (ASICs) that make one particular task more efficient. For example, Meta used the chips it designed with Broadcom specifically for its AI models aimed at generating ads and organic content.

    Wall Street analysts are still bullish on Broadcom and its custom AI chips. Mizuho analyst Vijay Rakesh recently reiterated his outperform rating on the stock and issued a $410 price target, implying an upside of 21% from current levels. Calling Broadcom the “King of AI Custom Silicon,” Rakesh sees ASIC's revenues rising and the company gaining broader interest in the AI ​​space.

    In the second quarter, Citadel sold about 82% of its long position in Broadcom. Several reasons can explain the sale. The company trades at 50 times forward earnings. Broadcom also still has a fairly small customer list in its custom chip business. While those few customers could potentially generate tens of billions in revenue for the company over time, things could become problematic if AI infrastructure spending dries up. It's also entirely possible that Citadel simply makes a profit after a good run.
