Who Is Buying AMD? Hedge Fund Activity in 2026

Advanced Micro Devices has positioned itself as the primary challenger to NVIDIA's AI GPU dominance — and hedge funds are placing significant bets on whether AMD can capture meaningful share. With the MI300 series gaining traction and a robust product roadmap, AMD's story in 2026 is one of AI opportunity and competitive execution. The question: are the world's smartest investors buying in?

In this analysis, we examine which hedge funds are buying, selling, and holding AMD based on the latest SEC 13F filings and what their moves signal about AMD's competitive position.

AMD at a Glance

Who's Buying AMD in 2026?

Based on Q4 2025 13F filings, several major hedge funds have been increasing their AMD positions:

1. Citadel Advisors (Ken Griffin)

Citadel holds a $3.9 billion position in AMD, comprising approximately 18.4 million shares. The fund increased its AMD stake by 7.41% in Q4 2025. This measured but meaningful increase suggests Citadel sees AMD as a strong secondary play on AI infrastructure, diversifying beyond NVIDIA exposure.

2. Millennium Management (Israel Englander)

Millennium boosted its AMD holdings by approximately 20% in Q4, bringing its total position to over $2.8 billion. Multiple pods within Millennium are independently bullish on AMD's data center GPU trajectory, particularly the MI300X and upcoming MI400 series.

3. Two Sigma Investments

Two Sigma increased its AMD exposure by roughly $900 million in Q4, with systematic strategies detecting favorable earnings revision momentum and increasing institutional accumulation patterns in the stock.

4. D.E. Shaw & Co.

D.E. Shaw added approximately $700 million to its AMD position in Q4 2025. The quant fund's models identify AMD as having strong momentum characteristics correlated with AI infrastructure spending trends.

5. Coatue Management (Philippe Laffont)

Coatue increased its AMD stake by 25% in Q4, with the tech-focused fund viewing AMD as the best risk-reward way to play the AI GPU competition. At a lower valuation than NVIDIA, Coatue sees AMD offering more upside per dollar of investment.

6. Tiger Global Management (Chase Coleman)

Tiger Global added approximately $1.5 billion in AMD stock during Q4 2025, seeing the company's competitive improvements as a catalyst for market share gains in the AI accelerator market.

Who's Selling AMD?

AMD has seen some notable institutional selling, particularly from funds with valuation concerns:

1. Berkshire Hathaway (Warren Buffett)

Buffett has never held AMD and has historically avoided semiconductor stocks with cyclical earnings profiles and intense competitive dynamics. Berkshire's absence is notable given the stock's prominence.

2. Renaissance Technologies

Renaissance reduced its AMD position by approximately 18% in Q4 2025. The quant fund's models may be detecting competitive headwinds from NVIDIA's Blackwell architecture and custom AI chip alternatives from hyperscalers.

3. Bridgewater Associates (Ray Dalio)

Bridgewater trimmed its AMD stake by roughly 22%, consistent with its macro-driven rotation away from high-beta semiconductor stocks toward more defensive positioning.

4. Several Growth-to-Value Rotators

Some funds that bought AMD in the sub-$100 range during 2023-2024 have been taking profits as the stock more than doubled. These are portfolio management decisions rather than thesis changes.

What AMD's Institutional Activity Signals

The AI GPU Competition Is Real

AMD's MI300 series has gained meaningful traction with cloud providers and enterprises. While NVIDIA still dominates with 80%+ market share in AI training GPUs, AMD has captured approximately 10-15% of the AI inference market — and institutional investors are betting this share grows. Citadel's $3.9 billion position with a 7.41% increase reflects cautious optimism about AMD's competitive trajectory.

The NVIDIA Alternative Thesis

Many hedge funds are buying AMD not as a replacement for NVIDIA but as a portfolio complement. Enterprise customers want a second source for AI chips to avoid vendor lock-in, and AMD is the most credible alternative. Funds like Millennium and Coatue hold both NVDA and AMD, sizing positions to reflect each company's competitive position.

Data Center Transformation

AMD's data center revenue — spanning EPYC server CPUs and Instinct AI GPUs — now represents approximately 50% of total revenue, up from 25% in 2022. This transformation from a PC-centric company to a data center-focused company is exactly the narrative shift that attracts institutional capital.

Valuation Relative to NVIDIA

At approximately 30x forward earnings, AMD trades at a meaningful discount to NVIDIA's 40x+. For hedge funds with strong AI conviction but valuation discipline, AMD offers similar thematic exposure at a lower multiple. This relative value argument is a key driver of institutional accumulation.

Sector Context: The AI Chip Landscape

AMD's competitive position must be understood within the broader AI semiconductor ecosystem:

• NVIDIA remains the dominant AI GPU provider — AMD is the strongest challenger
• Broadcom and Marvell compete in custom AI chips (ASICs), a different segment
• Intel continues to struggle with its AI accelerator strategy, leaving AMD as the primary x86 alternative
• Custom chips (Google TPU, Amazon Trainium, Microsoft Maia) are growing but serve primarily their creators
• The total addressable market for AI chips is projected to exceed $300 billion by 2027

For hedge funds, AMD represents a way to diversify AI exposure beyond NVIDIA while maintaining conviction in the secular trend. The competitive dynamics favor a duopoly structure where both NVIDIA and AMD benefit.

Frequently Asked Questions

How many hedge funds own AMD?

Over 3,800 institutional investors report holding AMD in their Q4 2025 13F filings. Among hedge funds specifically, approximately 850+ hold AMD positions, making it one of the most widely held semiconductor stocks in institutional portfolios.

What is Citadel's position in AMD?

Citadel Advisors holds approximately $3.9 billion in AMD stock (18.4 million shares) as of Q4 2025, having increased the position by 7.41% from the prior quarter.

Is AMD a better investment than NVIDIA?

This is the central debate in semiconductor investing. AMD offers a lower valuation multiple and potential market share gains, while NVIDIA offers dominant market position and proven execution. Most institutional investors hold both stocks in different sizes. Neither is objectively "better" — it depends on your investment thesis and risk tolerance.

Should I buy AMD because hedge funds are buying it?

Institutional activity is a valuable signal but not a standalone investment thesis. Multiple major funds are accumulating AMD, which suggests professional conviction. However, 13F data is delayed, strategies differ, and past institutional buying doesn't guarantee future returns. Use Freenance Smart Money to stay informed, and always make decisions based on your own research.
