**Strong post-opening legs and a decelerating but still robust weekly pace are the main drivers behind the near-even split between sub-$900 million and $900–920 million outcomes by August 31.** Released July 31 with a record $360 million domestic debut, the film reached roughly $786 million domestically by August 17 after a $145 million second weekend and an estimated $70 million third frame. This places it on track to add another $110–140 million over the next two weeks, depending on holdover strength and minimal late-summer competition. Traders appear focused on whether typical 40–50% weekend drops will keep the cumulative total below or push it just over the $900 million threshold by month-end, consistent with recent box-office tracking models projecting a final domestic total in the low-to-mid $900 millions. Historical Marvel legs and the absence of major new releases support modest upside, while the already-steep drop from opening weekend caps expectations for a larger surge.
