Bill Ackman's Pershing Square Made Amazon Its Fourth-Largest Holding by Dumping Alphabet. Here's the Thesis Behind the Switch.
Pershing Square Capital Management, led by Bill Ackman, sold Alphabet shares in Q4 2025 and said it did so to free cash for a new Microsoft position, while keeping Amazon as its fourth-largest holding at about 10% of assets. Pershing Square’s mid-year update expects Amazon earnings growth above 20% annually, citing AWS revenue growth of 37% and Q2 operating income up 43% to $27 billion.

The 30-second read
Why it matters
For traders, the actionable element is sentiment and positioning read-through: AMZN is framed as benefiting from AWS AI demand and retail margin improvement, while GOOG is framed as a capital-reallocation sale without new Alphabet-specific negatives.
Market read
This is primarily a fund-thesis and positioning update, not a new AMZN/GOOG corporate disclosure. It may modestly support AMZN sentiment if traders track large-investor conviction, but it is unlikely to be a standalone catalyst.
What to watch
The article cites AWS and operating income growth but does not quantify inference workload absorption timing, competitive pricing pressure, or the durability of retail margin expansion.
Background
The piece describes Pershing Square’s portfolio rotation, selling Alphabet while maintaining a large Amazon position, and reiterates the firm’s earnings-growth thesis for AMZN.
Ticker impact
Pershing Square kept Amazon as its fourth-largest holding after selling part of Alphabet, reiterating >20% annual earnings growth driven by AWS and e-commerce.
Near-term impact likely limited because it is a 13F/thesis update rather than a new AMZN corporate disclosure; sentiment may support dips.
The newest concrete items are Pershing Square’s stated rationale and cited operating metrics (AWS growth acceleration, operating income jump) but the trading catalyst is fund positioning commentary, not a fresh AMZN filing or guidance print.
Pershing Square started selling Alphabet in Q4 2025 and cited freeing cash for Microsoft, implying reduced conviction versus its prior stance.
Limited direct price impact expected; any effect is indirect via sentiment from a large investor trimming.
The text provides no Alphabet-specific new fundamentals, guidance, or regulatory/legal developments, only that Pershing Square reduced exposure.
Market effects
Reinforces the market narrative that cloud AI demand (AWS) can reaccelerate growth and support margins, which can influence broader large-cap cloud sentiment.
Primarily US large-cap tech sentiment; no explicit regional macro linkage.
AI infrastructure and cloud capex absorption themes can affect global tech risk appetite, but the article is fund-thesis focused.
Counterpoint
Pershing Square’s bullish framing may underweight the risk that AI-driven capex keeps free cash flow pressured longer than expected, even if revenue growth accelerates.
