Obsession’s exceptional box-office trajectory since its May 15 wide release underpins the 92.9% market-implied odds. The low-budget horror title delivered a modest $17.2 million opening yet posted a rare 39% second-weekend increase, a hold pattern rarely seen outside major event films, and has already cleared $126 million domestically with strong per-screen averages persisting into mid-June. Its sub-$1 million production cost and positive critical reception have fueled word-of-mouth that continues to drive attendance weeks after competitors opened. The Devil Wears Prada 2’s earlier May 1 debut produced a larger initial gross but lacks comparable sustained momentum, while Mandalorian & Grogu, Mortal Kombat II, and Backrooms trail further behind. An upset would require one of those titles to post historically unprecedented multi-week holds through June 30, an outcome that current tracking and historical precedent make highly improbable.
