Ackman Sold Alphabet for Netflix. The Real Rotation Is From AI Capex to Cash Flow

Pershing Square Holdings’ interim report for the six months ended June 30, 2026 records that the firm exited Alphabet and established a new Netflix position. The same report says Pershing Square made six new investments during the period after market dislocation created opportunities below its estimate of intrinsic value. Pershing Square moved from an AI infrastructure spender to a cash-generating media platform.

Berkshire Hathaway’s June 2026 investment was a company-level purchase, not proof that Warren Buffett personally placed the trade. The SEC offering document says the investment added to a position Berkshire Hathaway had built since the third quarter of 2025, while Pershing Square’s exit occurred over the same six-month reporting period. The two investors are expressing different cash-flow horizons, not necessarily opposite views of AI.

The timing matters. Berkshire Hathaway added Alphabet through a negotiated private placement, while Pershing Square’s public disclosure came after the first half had ended. That makes the episode a useful portfolio-construction signal, but a weak short-term trading signal: neither filing shows that one investor reacted directly to the other.

Alphabet’s operating business is not deteriorating. Q2 revenue rose 24% to $119.8 billion, Search revenue increased 17% to $63.3 billion, and Google Cloud revenue surged 82% to $24.8 billion. The tension is capital intensity: AI investment lifted growth while pushing quarterly free cash flow to negative $5.9B.

Netflix delivered less top-line growth than Alphabet, but its earnings profile is already shaped by monetization rather than capacity construction. Q2 revenue rose 13% to $12.56 billion, operating margin reached 33.4%, and free cash flow was $1.525 billion. Pershing Square’s report adds that Netflix has expanded its operating margin from 21% to roughly 31.5% over its investment period and converts about 90% of earnings into free cash flow. Netflix turns scale into cash before the next investment cycle begins.

The important second-order effect is not that Netflix replaces Alphabet in the AI economy. It is that the two companies sit at different points in the spending cycle. Alphabet is committing heavily to servers, networking, data centers, and energy, while Netflix is using cloud infrastructure, content, and distribution partners to scale a finished consumer product. The nearer-term beneficiaries are the channels that monetize viewing, not every company exposed to AI spending.

The linkage is asymmetric. Amazon and Broadcom can benefit from a broad infrastructure cycle, but the filings do not show that Pershing Square’s Netflix purchase materially changes their revenue. By contrast, Roku and Comcast sit closer to the point where viewing becomes advertising, subscription, or bundle revenue. That makes them more sensitive to the durability of streaming demand.

The evidence supports a narrower conclusion than “Ackman sold AI.” Alphabet is producing exceptional growth: Q2 revenue rose 24%, Cloud revenue rose 82%, and Cloud operating margin expanded to 35.6%. But the company is spending at a scale that temporarily overwhelms free cash flow. Netflix is growing more slowly, yet its 33.4% quarterly operating margin, $1.525B of free cash flow, roughly $3B advertising target, and large buyback authorization make the earnings path easier to see. Pershing Square chose visible monetization over maximum optionality.

That does not make Netflix the safer business. Its $25.1B content obligation balance and dependence on hit-driven programming create a different form of duration risk. Nor does Berkshire Hathaway’s Alphabet purchase prove that the market is wrong about AI spending. The most defensible reading is that the post-2025 megacap trade is separating into two buckets: companies funding the next platform layer and companies harvesting the current one.
