Ackman’s $400M Netflix Redemption Bet Just Dropped the Final Verdict on the Streaming Wars

Bill Ackman lost more than $400 million on Netflix in 2022, bailing on his $1 billion position just months after buying in. Now he’s back with a stake that makes up 4.9% of Pershing Square’s entire portfolio, sending Netflix stock up as much as 4.7% in Thursday trading. That’s not just a random hedge fund flip play. The streaming sector has spent nearly a decade burning tens of billions in cash chasing market share, with most investors writing off every player as permanently unprofitable. The past year has been particularly rough for Netflix, too. Its stock is down 42% from its June 2025 highs, after a failed bid to acquire Warner Bros. Discovery and widespread concerns over slowing user engagement. Even top insiders sold off earlier this year, with the CEO and CFO both dumping stock in early August. Third quarter revenue guidance also came in slightly below analyst expectations after Q2 earnings, leading most Wall Street firms to mark Netflix as a mature, low-growth stock unworthy of a premium multiple. That’s what makes Ackman’s return so jarring, and why the market reacted so sharply to the news.

Pershing Square disclosed the 3.15 million share position in its semiannual report released Wednesday evening. The stake is a meaningful endorsement for a fund that only holds fewer than a dozen concentrated positions at any given time. The firm’s shareholder letter makes its case explicitly: Netflix has effectively won the streaming wars. Pershing expects the company to compound revenue at a double-digit rate, with content costs growing more slowly than revenue to drive consistent margin expansion. The operational metrics back that argument. Netflix’s ad-supported tier is gaining traction fast, with 2026 U.S. Upfront advertising commitments nearly doubling year over year. The company expects the ad tier to generate approximately $3 billion in revenue in 2026, creating a genuine second revenue engine outside of traditional subscriptions. Its recent push into live sporting events is also drawing in new viewer segments that historically never used Netflix, broadening its audience base without steep increases to content costs. Right now, Netflix trades at 24 times earnings, well below its three-year average multiple of 43. The broader market posted only modest gains Thursday, with the S&P 500 and Dow up 0.2% and the Nasdaq up 0.1%. Netflix’s 3.5% mid-morning gain outpaced all three indexes by a wide margin, driven entirely by the Pershing Square disclosure.

For years, streaming platforms competed almost exclusively on subscriber count, throwing cash at expensive original content and steep subscriber discounts to hit quarterly targets. That model left nearly every major player bleeding cash, with no clear path to sustainable profitability. Netflix’s current playbook is the first proven blueprint for long-term streaming success that other platforms will be forced to copy. It monetizes price-sensitive users through the ad tier instead of pushing them to churn with repeated price hikes. It adds high-demand live sports content to attract ad-friendly, high-income viewers that never cared about its scripted original slate. It keeps content cost growth under control, instead of overpaying for every high-profile showrunner or IP that hits the market. The current valuation discount is unsustainable for a company with consistent double-digit revenue growth and expanding margins. The recent insider sales and soft Q3 guidance are short-term noise, not structural threats to the business. Institutional investors will follow Ackman’s lead over the next two quarters, pushing Netflix’s earnings multiple back up to at least 35 by the end of 2025.
