Ken Griffin has built a fortune spotting inflection points before the crowd, and his latest move is a bet that a plain-vanilla index fund tied to gold can outgun the market’s flashiest trades. While Bitcoin, Nvidia and the S&P 500 have defined this cycle’s risk-on boom, Griffin is quietly steering capital toward a different kind of winner, one that reflects his growing conviction that the next phase of the cycle will reward defense as much as offense.

Instead of chasing the same momentum names that have already multiplied, he is leaning into an exchange-traded fund that tracks bullion and has, so far this year, outpaced those headline-grabbing assets. For an investor whose flagship hedge fund has already delivered double-digit gains, the shift underscores a broader message to Wall Street: when someone with Griffin’s track record rotates into a conservative hedge, it is worth asking what he sees coming.

Why Ken Griffin’s gold ETF bet matters now

At the core of Griffin’s latest repositioning is a new stake in the SPDR Gold Shares ETF, a move that signals he is willing to trade some upside in speculative tech for the perceived safety of hard assets. One of Griffin’s more notable trades in the third quarter was starting a position in the SPDR Gold Shares ETF, identified as the Gold Shares ETF on the NYSEM, which tracks the price of physical gold rather than a basket of companies. In a year when digital assets and chipmakers have dominated headlines, the fact that this fund is described as “crushing” Bitcoin, Nvidia and the broad S&P 500 in 2025 reframes the narrative about what is actually working in portfolios.

Griffin’s choice is not just a tactical trade, it is a macro call on how investors will behave if growth cools and volatility returns. Reporting on his move into this index fund notes that investors often buy gold in times of uncertainty and when they fear that inflation or policy mistakes will ultimately hurt economic growth, a pattern that helps explain why the Gold Shares ETF has been able to outpace risk assets so far this year. The analysis of this shift, laid out in detail in a piece on how Billionaire Ken Griffin Buys an index fund that is outperforming those benchmarks, frames gold as a hedge against exactly the kind of late-cycle risks that are now creeping into the outlook.

Inside Citadel’s playbook: from AI winners to defensive hedges

To understand why this gold-heavy index fund is so striking, it helps to look at how aggressively Griffin has embraced the artificial intelligence boom. Earlier this year, filings showed that Microsoft, trading under the ticker MSFT on the NASDAQ, ranks as Griffin’s largest holding, and that Citadel Advisors more than doubled its stake in the tech giant as part of a broader push into AI leaders. Coverage of those moves notes that Microsoft (NASDAQ: MSFT) sits at the top of his portfolio and that Citadel Advisors increased its exposure to a cluster of artificial intelligence stocks, underscoring how central the theme has been to his equity strategy.

That same reporting, which details how Griffin more than doubled his stakes in several AI names, shows a manager who is anything but shy about owning the future of computing. Yet his willingness to pair those aggressive growth bets with a sizable allocation to a gold ETF suggests he is not treating AI as a one-way trade. Instead, he is building a barbell: on one side, high-conviction positions in companies like Microsoft that are driving the AI buildout, and on the other, a liquid, commodity-backed index fund that can cushion the portfolio if those same growth expectations start to deflate.

From Nvidia trimming to Bitcoin skepticism

Griffin’s pivot toward gold also fits with a broader pattern of cooling enthusiasm around the most crowded trades of the cycle, especially Nvidia and Bitcoin. One detailed breakdown of his positions explains that Billionaire Ken Griffin Sold 79% of Citadel’s stake in Nvidia, a reminder that even as the chipmaker’s shares surged, he was willing to lock in gains and reduce exposure. That decision looks more deliberate when set against the backdrop of Nvidia’s extraordinary run, with another analysis pointing out that Nvidia (NASDAQ: NVDA) shares have advanced 1,080% since January 2023 as demand for artificial intelligence infrastructure exploded.

Other billionaire investors have been making similar adjustments, rotating out of Nvidia and into vehicles tied to digital assets, but Griffin’s path has been more nuanced. One report notes that Yet the hedge fund managers who sold Nvidia and bought the iShares Bitcoin Trust, trading on the NASDAQ under the ticker IBIT, were effectively swapping one high-volatility asset for another, as described in coverage of how Yet the managers moved between Nvidia and Bitcoin Trust. A separate analysis of the fourth quarter shows that In the same period, several prominent managers sold Nvidia, listed as NVDA, and bought Bitcoin exposure through an ETF, a pattern captured in a piece that notes how In the fourth quarter those trades reshaped their largest positions excluding options contracts. Griffin, by contrast, is using a gold index fund as his primary hedge, a choice that distances him from the Bitcoin trade even as peers embrace it.

Citadel’s performance and Griffin’s appetite for risk

Griffin’s decision to lean into a conservative hedge carries more weight because it comes from a manager whose core strategies are still delivering strong returns. Citadel’s multistrategy Wellington fund, its largest vehicle, finished 2024 up 15.1%, according to a person familiar with the results, a performance that kept it firmly in the top tier of multistrategy funds. A separate discussion of those numbers, shared among market watchers, reiterates that Ken Griffin’s Citadel multistrategy Wellington fund finished 2024 up 15.1%, even as the S&P 500 was up 27%, highlighting how his approach prioritizes risk-adjusted returns over simply matching the index.

That performance sits on top of a broader empire that spans hedge funds, market making and asset management, all housed under the Citadel brand that Griffin founded and still leads. Within that structure, Citadel Advisors is described as one of the most successful hedge funds in history as measured by net gains, a point underscored in coverage that refers to how Billionaire Ken Griffin runs Citadel Advisors and has built it into a powerhouse. When a manager with that record chooses an index fund tied to gold over doubling down on Bitcoin or Nvidia, it sends a signal about how he is calibrating risk at this stage of the cycle.

The billionaire behind the trade: lifestyle, real estate and signaling power

Griffin’s investment decisions are amplified by the public fascination with how he spends his money, which in turn shapes how investors read his moves. Profiles of his personal life highlight a string of eye-catching purchases, including a $90 m St. Tropez home and a $45 m dinosaur skeleton, with the same report also spelling out that he bought a $90 million St. Tropez property and a $45 million fossil as part of a broader pattern of trophy acquisitions. Those details, laid out in a feature on how Billionaire Ken Griffin has made some of his most extravagant and unusual purchases, reinforce his image as someone who is comfortable making bold, highly visible bets when he believes the asset is worth it.

That same instinct shows up in his real estate footprint in Palm Beach, where he has assembled a mega-estate on a stretch of coastline often referred to as Billionaires’ Row. Local coverage describes how Palm Beach has long been a playground for the world’s elite, but that Griffin’s holdings there represent a new scale of ambition, with one profile calling it a Legacy of Luxury Unfolds on Billionaires Row in Palm Beach. Another rundown of his major purchases and philanthropy notes that Palm Beach resident Ken Griffin has become one of the area’s most prominent buyers and donors, with the piece on What to know about his spending and giving detailing how Ken has reshaped parts of the local landscape. When someone with that level of visibility and signaling power chooses a gold index fund that is described as Crushing Bitcoin and Nvidia rather than the flashiest new token or stock, it reinforces the idea that caution is becoming fashionable again among the very top tier of investors.

What Griffin’s gold move signals for everyday investors

For individual investors watching from the sidelines, the temptation is to treat Griffin’s latest trade as a simple tip sheet: buy the same index fund and hope for the same outcome. The reality is more complicated. The analysis of his gold ETF position emphasizes that the fund is beating Bitcoin, Nvidia and the S&P 500 in 2025, but it also notes that this outperformance is tied to a specific macro backdrop of uncertainty and concern about future growth. The piece that frames how Index Fund That is Crushing Bitcoin and Nvidia in 2025 makes clear that gold’s edge is not guaranteed to persist if inflation cools faster than expected or if risk appetite roars back.

What I take from Griffin’s move is less a directive to copy his trades and more a reminder to think in terms of balance and scenario planning. He is still heavily invested in AI leaders like Microsoft through Citadel Advisors, as documented in the reporting on his largest holdings, but he is pairing that exposure with a defensive position in a gold-backed ETF that can help if those growth bets stumble. For investors who have spent the last few years chasing Bitcoin, Nvidia and the S&P 500, the message is straightforward: even the most aggressive, well-resourced players are now carving out room for hedges. In a market where the S&P 500, often shortened to simply 500 in shorthand references, has already delivered strong gains, following Griffin’s example may mean not abandoning growth, but making sure there is something in the portfolio that can hold up if the music slows.
