(Bloomberg) -- Reed Hastings’s fortune was already on the decline before Netflix Inc., the streaming giant he co-founded, reported its surprising first-quarter earnings.

Now with Netflix shares plunging 31% after it lost subscribers for the first time in a decade and the firm forecasting that 2 million more will soon leave, his wealth wipeout ranks among the biggest in the world, according to the Bloomberg Billionaires Index.

Hastings, 61, has a net worth of $3.6 billion, down 46% from the start of the year. That’s the second-steepest drop among U.S. billionaires tracked by the Bloomberg index, exceeded only by Ernest Garcia III, the chief executive officer of Carvana Co., which has tumbled 58% this year.

His wealth is still mostly tied to the performance of Netflix. In 2020, he cashed in on pandemic-fueled subscriber growth with a stock sale worth $616 million.

While Hastings has said for years that he doesn’t want advertising and is fine with password sharing, the company is changing course after losing 200,000 subscribers in the first quarter. It said it would introduce a cheaper, ad-supported option in coming years and will start cracking down on people circulating their login information.

Some mega hedge funds may also be feeling the pain. 

Hedge fund Pershing Square Capital Management made a big bet on Netflix in January, when Bill Ackman tweeted that he’d bought 3.1 million shares of the company.  

Chase Coleman’s Tiger Global Management owned more than 1 million shares of Netflix as of year-end, while Philippe Laffont’s Coatue Management had about 931,000 shares. Netflix was Maverick Capital’s fourth-biggest U.S. stock position as of Dec. 31, holding more than 420,000 shares.

Other hedge funds, including Viking Global Investors and D1 Capital, ditched their Netflix stakes entirely at the end of last year. It was a particularly interesting move for D1, as founder Dan Sundheim said in 2019 that Netflix could trade above $1,000 a share by 2024. It was trading at $240.49 at 9:35 a.m. in New York.
