For months, billionaire Ken Griffin famously blasted the artificial intelligence boom as a massive overhyped bubble, openly dismissing the technology's outputs as garbage. But that aggressive skepticism is officially dead. In a stunning philosophical U-turn that has sent shockwaves through Wall Street, the Citadel founder has completely reversed his stance, declaring that he was wrong and warning that the real AI supercycle hasn't even begun.
When a titan of Griffin's stature pivots this hard, active investors must pay attention. As the mastermind behind the most profitable hedge fund in human history, Griffin commands a personal net worth of over $50 billion and orchestrates a global market making empire. His macro shifts dictate where billions of dollars of institutional liquidity flow next.
This newfound AI bullishness is already bleeding directly into Citadel's massive portfolio. In a calculated tactical rotation, Griffin has aggressively trimmed his exposure to early-stage crowded AI winners. He slashed his position in Nvidia by 13.4% liquidated 19.2% of his Microsoft shares, cut his exposure to Amazon by over 40%.
But this wasn't a retreat from tech. It was a reallocation of capital. Griffin is rotating out of overextended hardware providers and positioning Citadel at the absolute vanguard of the next infrastructure wave. Let's break down the data from his latest 13F filing and unpack the top five powerhouse stocks Ken Griffin is aggressively buying right now to front run the next leg of the AI revolution.
Let's begin with the absolute crown jewel of Ken Griffin's architectural portfolio shift, Micron Technology, trading under ticker symbol MU. Looking at the filing data, Citadel aggressively increased its position in Micron by over 50% loading up on an additional 1.5 million shares to bring their total stake to a massive 1.6 billion dollars.
Griffin clearly sees that the agentic AI era is shifting from raw processing power to massive memory and storage demands. Micron is capitalizing heavily on severe global memory shortages. In its last reported quarter, revenue tripled year-over-year to 23.86 billion dollars with gross margins hitting a spectacular 75%.
Management is already guiding for next quarter revenue to surge to 33.5 billion dollars. With gross margins climbing to an eye-popping 81%. The company is rapidly evolving from a cyclical memory supplier into an elite AI infrastructure titan. Key catalysts include the rollout of their revolutionary 245 terabyte data center solid state drives, which slash data center rack space requirements by 82%.
With its advanced next generation DRAM technology vastly outperforming standard modules in power efficiency, Micron boasts an exceptional growth profile while still trading at a remarkably cheap 14 times forward earnings. Pivoting from the massive data demand in core memory, the second powerhouse on our list is SanDisk Corporation, ticker symbol SNDK.
Another massive high conviction play where Ken Griffin is capitalizing on a heavily misread market trend. Looking at portfolio, Citadel increased its stake by over 50% scooping up an additional 205,000 shares to bring their total holding to 386 million dollars. While short-sighted investors recently dumped memory names out of cyclical fears, Griffin is front running a structural under supply in the AI NAND super cycle.
SanDisk is executing a fundamental reset. In its recent fiscal third quarter, revenue skyrocketed 251% year-over-year to nearly 6 billion dollars while gross margins expanded to an exceptional 78.4%. Management is guiding for another explosive quarter ahead projecting revenue to reach approximately $8 billion with gross margins climbing toward 80%.
The company is effectively crushing traditional industry cyclicality through its revolutionary new business model, locking in five multi-year customer agreements that secure a staggering $42 billion in minimum contractual revenue. Future catalysts are highly compelling, including the upcoming ramp of high-density BICS8-based enterprise solid-state drives designed to eliminate severe AI inference bottlenecks.
Backed by an extended joint venture providing superior cost economics and a debt-free balance sheet, SanDisk represents a premier infrastructure play. While memory and NAND storage provide the baseline architecture, the third stock on our list represents the undisputed baseline for all advanced silicon processing globally.
rading under ticker symbol TSM. Looking at 13F, Citadel increased its holding by nearly 35% adding 1 million shares to bring its total investment to a staggering $1.4 billion. Griffin's thesis here is brilliant. He is completely bypassing the fierce architecture wars between standard GPUs and custom accelerators.
Whether hyperscalers deploy Nvidia's newest Blackwell architecture or build custom AI chips to break their software dependence, TSMC wins either way because it fabricates virtually 99% of all AI server accelerators globally. This architecture-agnostic moat is driving historic financial performance. In its latest quarter, high-performance computing reached a record 61% of total revenue, propelling gross margins to an exceptional 66.2%.
The future catalysts for TSMC are highly compelling, led by the high-volume production ramp of their next-generation 2-nanometer node. This advanced technology carries massive pricing power with wafer prices expected to exceed $30,000. Backed by an industry-leading 72% pure foundry market share and massive global capacity expansions, TSMC remains a remarkably valued, highly profitable foundation for the next leg of the AI super cycle.
Stepping away from back-end semiconductor fabrication and into the world of applied, real-world robotics, our fourth stock is Tesla, ticker symbol TSLA, a company where Ken Griffin is aggressively betting on its transition from a pure automaker to a physical AI powerhouse. Looking at its holdings, Citadel absolutely loaded up on Tesla, expanding its position by a staggering 134.79% to bring its total ownership to 2.1 million shares, valued at $778 million.
While retail investors sweat over Tesla's headline forward PE ratio of 190 times, Griffin understands that traditional accounting metrics are completely mispricing this tech giant. Because Tesla invests so aggressively in expansion, its accounting earnings heavily mask its true economic powerhouse status.
Operationally, the business model is proving its resilience. Tesla's retail sales in China surged over 22% year-over-year in May, while European registrations skyrocketed over 46% in April. This core automotive stability gives Tesla a pristine net cash balance sheet that funds its real growth catalysts, full self-driving technology and the monetization of its upcoming robotaxi fleet.
Furthermore, with SpaceX approaching its highly anticipated IPO, analysts place an 80% probability on a blockbuster Tesla-SpaceX merger next year. Such a combination would unify Elon Musk's autonomous data, XAI models, and Starlink global connectivity under one massive ecosystem umbrella, triggering a massive institutional revaluation.
Finally, completing this infrastructure rotation by connecting physical AI back to the massive internet ecosystem, our fifth stock is Meta Platforms, trading under ticker symbol M E T A. Looking at portfolio, Griffin expanded his Meta holding by a massive 128.58% purchasing an additional 1 million shares to build a total stake worth $1 billion.
While short-sighted investors are punishing Meta for its massive capital expenditure cycle, Griffin is capitalizing on a critical trend that Nvidia just confirmed. Recommendation systems are driving a massive wave of infrastructure spending. Meta is directly converting this data infrastructure into immediate monetization.
In its core advertising business, AI-driven performance gains accelerated ad price growth by 12% year-over-year in the latest quarter. Overall revenue is tracking toward a powerful 27% year-over-year expansion to finish 2026 at $255.4 billion. The primary catalyst for Meta are its rapidly scaling non-advertising revenue levers.
This includes the launch of premium consumer and business Meta One chatbot subscriptions starting at $7.99 per month, which are unlocking recurring software revenue engines. Simultaneously, weekly business conversations on WhatsApp surged tenfold in the first quarter, while user adoption of Meta's AI smart glasses tripled year-over-year.
Currently trading at a clear valuation discount relative to its Magnificent Seven peers, Meta represents a premier de-risked opportunity to capture the monetization phase of the AI super cycle. Ken Griffin's massive portfolio overhaul proves that the early speculative phase of the AI trade is over. By rotating billions of dollars away from traditional megacaps and into hardware infrastructure and software monetization giants, Citadel is front-running the real super cycle. The data is clear. Now it's time to position your portfolio accordingly.
