Obsession’s market-implied 100% probability on a $24-27 million fourth weekend reflects its unprecedented theatrical legs as a sub-$1 million horror romance. The Curry Barker-directed Focus Features release opened modestly in mid-May but posted rare consecutive weekend gains driven by exceptional word-of-mouth and viral social buzz, culminating in a modest 7% drop to $25.6 million domestically last frame—the largest fourth-weekend haul ever for the genre. With domestic totals already exceeding $152 million and limited competition on the horizon, traders see little room for deviation. An upset into adjacent ranges would require either a sudden influx of major new releases or an abrupt erosion of audience engagement that current exit polls and tracking have not signaled.
