Why the chill has lifted on Netflix for Ackman and others
Pershing Square Capital Management, run by Bill Ackman, disclosed it bought 3.15 million shares of Netflix (about 4.9% of its ~$23B portfolio). In its interim report, it said Netflix has “won the streaming wars,” projecting double-digit revenue growth and slower content-cost growth, citing a valuation discount. Netflix shares rose 3.4%. Netflix also projected ~$3B 2026 ad revenue and reported Q1 2026 revenue of $12.25B (+16% YoY).
How this was made

The 30-second read
Why it matters
The key new information is Pershing Square’s disclosed purchase and its explicit bull-case framing around streaming dominance, margin expansion from content cost discipline, and a rapidly scaling advertising business.
Market read
Traders can reassess Netflix’s near-term sentiment and valuation support given a high-profile re-entry plus concrete ad-business traction details and a same-day market reaction.
What to watch
The article also notes studio closures in Games; traders may discount the ad thesis if overall content economics or engagement metrics deteriorate.
Background
Ackman exited Netflix in 2022 after a painful period tied to the first subscriber decline in a decade, and Pershing Square is now re-entering with a sizable stake.
Ticker impact
Pershing Square disclosed it bought 3.15 million Netflix shares, about 4.9% of its portfolio, citing double-digit revenue growth and a valuation discount.
Shares already jumped 3.4% on disclosure; further upside depends on whether ad revenue and buyback execution confirm the bull case.
This is a fresh, attributable position disclosure plus specific thesis points (ad commitments, FCF conversion, buyback authorization) and a same-day price reaction, but it is not a new Netflix guidance print or earnings release.
Market effects
Reinforces the streaming sector narrative that advertising can materially de-risk monetization and support higher multiples than pure subscription-only models.
Limited direct regional spillover; primarily US large-cap sentiment for media/streaming.
Netflix’s global ad reach and sold-out FIFA Women’s World Cup sponsorships highlight international demand strength for streaming ad inventory.
Counterpoint
A large buyback and ad growth narrative may not offset subscription churn risk or content cost inflation if competitive intensity returns.
