Key Takeaways
  • • Bill Ackman, founder of Pershing Square Capital Management, says AI hyperscalers' revenue growth will exceed analyst estimates over the next several years, per his November 2 quarterly letter to investors.
  • • Ackman estimates hyperscalers could earn pre-tax returns on invested capital of 15% to 25%, which he calls conservative.
  • • Pershing Square argues analyst estimates penalize hyperscalers for current buildout costs while underweighting future revenue and free cash flow, and that capital intensity will fall under either growth scenario.
  • • Ackman says hyperscalers have virtually no net debt and can fund most capex from core cash flows, distinguishing them from debt-strained neocloud providers.
  • • The Nasdaq 100 has fallen toward correction territory since its early October peak, erasing roughly $2 trillion in index value.
Summary
Bill Ackman, the billionaire founder of Pershing Square Capital Management, remains bullish on the largest spenders on artificial intelligence infrastructure despite growing investor unease over capital expenditure. In his quarterly letter, shared on November 2, Ackman acknowledged that the so-called picks-and-shovel trade has outperformed AI hyperscalers this year, but argued that the market is underestimating the biggest capex spenders.

The backdrop is a mixed third-quarter earnings season. Big Tech firms have largely reported strong results, yet investors are demanding evidence of returns on heavy AI spending. According to the report, the sell-off since the early October peak has pushed the Nasdaq 100 toward correction territory and removed about $2 trillion from the index. Pershing Square holds stakes in several of the largest spenders, including Microsoft, Meta, and Amazon.

Ackman wrote that analyst estimates penalize hyperscalers for the cost of the buildout today while assigning limited value to the significant future growth in revenue and earnings those investments are likely to generate. He said it is "highly probable" that hyperscaler revenue growth will exceed analyst estimates over the next several years. If it does not, he expects the companies to reduce capital expenditure from current levels. Under either scenario, he expects lower capital intensity and meaningfully higher free cash flow than current consensus implies.

Ackman estimated pre-tax return on invested capital of 15% to 25% for the hyperscalers, which he described as conservative. He argued the ultimate returns could be substantially higher because the companies can monetize capacity through higher-value inference services and first-party applications, rather than only through wholesale compute rental.

Ackman also cautioned against conflating the funding concerns and debt issues facing neocloud companies, which provide cloud computing to AI customers, with the spending of hyperscalers. He stated that the hyperscalers "are in a vastly stronger financial position," with virtually no net debt and the ability to finance the substantial majority of their capital expenditures from core business cash flows.
