As of 2024, the most viewed live stream event was the “FIFA World Cup 2022 Final” between Argentina and France, which took place on December 18, 2022. The final match, which saw Argentina win 4-2 in a penalty shootout after a 3-3 draw, attracted an estimated 3.5 billion total viewers, making it the most-watched live stream event in history across various platforms, including television and online streaming.
However, if we’re specifically talking about live streaming on platforms like YouTube, the most viewed live stream event was the “YouTube Live Stream of the 2023 Indian Premier League (IPL) Cricket Final”, which drew more than 25 million simultaneous viewers during the peak of the event, according to YouTube’s metrics for the IPL.
Note that live stream viewership records can fluctuate rapidly, especially with large events like sports finals, music concerts, or gaming tournaments. So while the World Cup holds the title for the broadest audience, platform-specific records may vary.
