**Spider-Man: Brand New Day** delivered a record $360 million domestic opening weekend but followed with an estimated $145 million in its second frame, landing comfortably below the 180 million threshold that now carries 100% implied probability on Polymarket. The roughly 60% drop aligns with historical patterns for major superhero launches, including Avengers: Endgame, while still ranking as the third-highest second weekend ever. Strong word-of-mouth, minimal competition, and continued international strength have sustained momentum, yet the sophomore figure remains far short of higher brackets. Final actuals and any late adjustments will confirm resolution, with only extreme reporting anomalies likely to shift the current trader consensus.
