Squid Game, the biggest and most-watched series on Netflix is estimated to be worth almost $US900 million ($A1.2 billion) for the streaming giant, Bloomberg News reports.
The nine-episode thriller, in which contestants play childhood games with deadly consequences in a bid to win 45.6 billion won ($A52 million), became an international hit when it launched last month.
In comparison to its estimated net worth, the show cost just $US21.4 million ($A28.8 million) to produce, Bloomberg said.
According to the report, about 132 million people have watched at least two minutes of the show in its first 23 days, easily breaking the record set by US drama Bridgerton, which was streamed by 82 million accounts in its first 28 days.
Netflix had earlier announced the show had amassed 111 million fans, but Bloomberg said those figures were based on slightly older data.
