Billionaire Money Managers Have a Clear Favorite Artificial Intelligence (AI) Stock -- and It's Not Nvidia or Palantir

Billionaire fund managers are strategically reallocating AI exposure, largely divesting from high-performing Nvidia and Palantir due to concerns over historical tech bubble patterns and their elevated valuations, notably Palantir's 137 P/S ratio. Conversely, Meta Platforms has emerged as the favored AI investment among top managers, appearing as a significant holding for several, driven by its robust advertising revenue, successful AI integration for ad performance, future metaverse potential, substantial cash reserves, and a comparatively reasonable valuation.

Analysis

Analysis of recent 13F filings reveals a significant strategic rotation within the artificial intelligence (AI) sector by prominent billionaire fund managers. Despite exceptional performance, with stock price increases of approximately 1,150% for Nvidia (NVDA) and 2,810% for Palantir (PLTR) since the start of 2023, influential investors including Stanley Druckenmiller and Stephen Mandel have completely exited or substantially reduced their positions. This divestment appears driven by two primary concerns: the historical precedent of tech bubbles bursting after periods of intense hype, and prohibitively high valuations. Specifically, Nvidia's trailing price-to-sales (P/S) ratio exceeds 30, while Palantir's is at an extreme 137, levels seen as unsustainable. Conversely, Meta Platforms (META) has emerged as the clear institutional favorite. It stands as the top holding for four major funds, including Tiger Global and Coatue Management. This preference is underpinned by Meta's dominant advertising business, which accounted for nearly 98% of its $89.8 billion in sales in the first half of 2025 and is supported by 3.48 billion daily active users. The company's investments in AI are already yielding tangible results, enhancing ad-targeting and contributing to a recent revenue beat. Furthermore, Meta's strong financial position, with over $47 billion in cash and a projected annual sales growth rate of 15% or more, supports a valuation considered reasonable at a 25.8 forward P/E ratio.

Key Decisions for Investors

• Investors holding Nvidia and Palantir should note the profit-taking by top-tier managers, which signals concerns over extreme valuations and the potential for a market correction in high-flying AI names.
• Consider Meta Platforms as a potentially more defensive AI investment, as its strong institutional backing is rooted in a profitable core advertising business, successful near-term AI integration, and a more reasonable valuation.
• The observed market rotation suggests a shift in strategy from speculative, pure-play AI stocks to established technology leaders that are embedding AI into existing, revenue-generating platforms, warranting a review of AI portfolio allocations.
• Monitor Palantir's price-to-sales ratio, cited at an exceptional 137, as its ability to sustain such a premium is a key risk factor highlighted by the institutional divestment.
