Monster: The Lizzie Borden Story seized the top US Netflix ranking within days of its September 17 premiere, driving the market’s overwhelming 98.2% implied probability through strong initial streaming metrics and franchise momentum from prior Ryan Murphy true-crime seasons. All eight episodes dropped simultaneously, capitalizing on built-in audience interest in the anthology’s shift to its first female subject, even amid mixed critical reception around 44% on Rotten Tomatoes. Sustained chart leadership through the weekend has reinforced trader consensus on its dominance for the week. An upset would require a major new release or sharp mid-week drop-off in viewership, scenarios that remain possible given the volatility of binge-driven streaming performance.
