Euphoria Season 3 Trailer Breaks HBO Max Record

HBO's Euphoria Season 3 trailer drew nearly 100 million views within 48 hours of release, becoming the largest original-series debut in HBO Max history. The trailer follows a four-year hiatus and previews a season that jumps five years forward with a darker, film-noir-inspired tone. Warner Bros. Discovery did not name the previous 48-hour record holder, but the performance places Euphoria alongside past HBO tentpoles such as Game of Thrones and The Last of Us. The trailer's record arrival underscores strong fan anticipation ahead of the show's April 12, 2026 premiere and contributes to a broader trend of massive trailer launches for major streaming tentpoles.
