Below’s commanding 98% market-implied odds stem from its sustained global chart dominance since the October 8 premiere, including record English-language viewership of 21.2 million in a single week and consistent top-three placement on Netflix’s worldwide TV rankings through late October. Strong critical reception, with an 87% Rotten Tomatoes score, combined with Josh Hartnett’s star power and the limited-series format’s binge appeal, has driven trader consensus around its momentum. Newer drops such as Lupin Part 4 or Nobody Wants This Season 3 could spark an upset if they post sharper weekly gains or capture broader international audiences before the October 27 snapshot.
