Billionaire Mandel's Lone Pine Capital Completely Exits Meta, Shifts Focus to Taiwan Semiconductor in Latest 13F Filing

The most consequential financial disclosure of the quarter arrived on February 17, 2026, when institutional investors managing $100 million or more in assets filed their quarterly Form 13F filings with regulators. These documents provide a window into the investment moves made by Wall Street’s most sophisticated portfolio managers over the preceding three months. Among the most striking repositioning decisions came from Stephen Mandel’s Lone Pine Capital, a hedge fund built on a foundation of value and growth investing that recently made a dramatic strategic pivot.

One of the most notable moves in these quarterly filings: Mandel’s fund completely liquidated its entire position in Meta Platforms, a holding that had delivered substantial returns over the prior two years. Simultaneously, Taiwan Semiconductor Manufacturing has become the portfolio’s new No. 1 holding, benefiting from an accelerated appreciation in chip sector valuations driven by artificial intelligence demand.

Why Lone Pine Capital’s Stephen Mandel Completely Exited His Meta Position

At the end of Q3 2025, Mandel’s Lone Pine Capital maintained 1,322,260 shares of Meta, representing approximately $971 million in invested capital and accounting for 7.1% of the fund’s total portfolio. By year-end 2025, every share of this social media giant had been removed from the fund’s holdings.

The decision to exit appears multifaceted. First, straightforward profit-taking likely played a role. Meta had been a continuous position since Q3 2023, and during the two-year holding period, shares had more than doubled in value. Mandel’s funds typically hold positions for an average of just 16.5 months, indicating management’s comfort with locking in gains when valuations advance materially.

However, the timing of this exit suggests additional factors beyond simple profit realization. In late October, Meta’s shares experienced a sharp pullback following the company’s AI capital expenditure guidance, which exceeded Wall Street expectations. Mark Zuckerberg has been systematically expanding his company’s AI spending commitments on a near-quarterly basis, a pattern that appears to have concerned Mandel’s investment committee. The scale and pace of Meta’s AI infrastructure investments raised questions about the timing of meaningful financial returns from these outlays.

This decision may ultimately prove regrettable for the portfolio. Meta maintains rock-solid advertising assets that command premium pricing from marketers globally. Even if the bulk of the company’s AI investments require several more years to meaningfully impact financial results, the exit appears premature given the company’s durable competitive advantages in social media.

Taiwan Semiconductor Manufacturing Emerges as Lone Pine’s New Top Holding

With Meta completely removed from the portfolio, Taiwan Semiconductor Manufacturing, more commonly known as TSMC, has ascended to become Lone Pine Capital’s largest position by market value. This transition is particularly noteworthy because Mandel’s fund has actually been systematically trimming its stake in the world-leading chip fabricator over the past three years. The shift occurred solely because TSMC’s stock price has experienced such a dramatic surge that the remaining position, though smaller, now represents the portfolio’s highest market value.

The primary driver of this appreciation is straightforward: the artificial intelligence revolution. Global demand for graphics processing units (GPUs) has skyrocketed, compelling TSMC to expand its monthly chip-on-wafer-on-substrate production capacity at an unprecedented pace. With AI hardware demand substantially outpacing available supply, Taiwan Semiconductor enjoys a healthy backlog of customer orders and meaningful pricing flexibility on its advanced offerings.

Yet it’s important to recognize that TSMC’s business foundation extends well beyond the current AI boom cycle. The company functions as a critical supplier of advanced semiconductors for smartphones, personal computers, and Internet of Things applications—segments that provide steady, predictable revenue streams independent of AI dynamics.

Mandel appears drawn to TSMC’s valuation efficiency as well. With a forward price-to-earnings multiple of approximately 21, this represents reasonable pricing for a nearly $2 trillion enterprise projected to expand sales by 24% in 2027. The combination of secular growth drivers, near-term AI tailwinds, and reasonable valuation metrics creates a compelling investment case for sophisticated portfolio managers evaluating semiconductor exposure.

Understanding the Strategic Shift: From Social Media to Advanced Semiconductors

The repositioning from Meta to Taiwan Semiconductor reflects a broader market reorientation toward the industries and companies positioned to benefit most directly from AI infrastructure buildout. Social media platforms, while benefiting from AI applications in content moderation and targeting, require massive upfront capital investments before demonstrating tangible returns. By contrast, chip manufacturers sit at the foundation of AI infrastructure, capturing revenue immediately as data centers expand capacity.

This strategic pivot by Mandel’s Lone Pine Capital exemplifies how even sophisticated institutional investors are recalibrating their portfolios in response to accelerating semiconductor demand. The decision to exit a profitable Meta position and allow the remaining TSMC stake to drive returns—despite trimming the position over time—demonstrates the magnitude of the AI chip cycle now underway.
