Billionaire hedge fund manager Bill Ackman has re-entered Netflix (NASDAQ: NFLX), building a new position worth approximately $1 billion through his firm Pershing Square Capital Management.

The move marks a striking reversal for Ackman, who first bet heavily on Netflix back in early 2022, committing roughly $1.25 billion of Pershing Square’s capital to the streaming giant.

At the time of that initial investment, Netflix shares had already suffered a steep sell-off driven by slower-than-anticipated subscriber growth, which Ackman appeared to view as a buying opportunity.

In shareholder communications following that purchase, Ackman expressed strong confidence in Netflix’s competitive advantages and its capacity to translate market leadership into sustained earnings growth.

Those convictions were short-lived in practice, however, as Ackman reversed course within weeks of establishing the position and sold his entire stake at a significant loss.

The speed of that exit drew considerable attention from Wall Street, given the size of the original commitment and the abrupt nature of the reversal.

Despite the painful outcome of that trade, Ackman indicated that he never stopped monitoring Netflix and continued to follow the company closely in the years that followed the exit.

Netflix has undergone considerable transformation since 2022, expanding its advertising-supported subscription tier, cracking down on password sharing, and delivering stronger financial results across consecutive reporting periods.

The company’s evolution into a more diversified revenue business appears central to the renewed investment thesis that has brought Ackman back to a stock he once abandoned under pressure.

Ackman’s new $1 billion stake signals that Pershing Square views the current moment as fundamentally different from the circumstances that led to the 2022 loss, though the firm has not publicly detailed the full scope of its updated rationale.

The re-entry will be closely watched by investors, given Ackman’s prominence in activist and high-conviction investing circles and the high-profile nature of his previous Netflix misstep.

Netflix remains one of the most widely followed stocks in the global entertainment and technology sectors, and institutional positioning in the company tends to attract significant market commentary.
