Karuppu, featuring Suriya and Trisha Krishnan, premiered on May 15, achieving a remarkable box office opening despite facing significant release challenges. The film garnered approximately ₹20.66 crore globally on its first day, with ₹14.40 crore net earned in India alone. It ran across 4,891 shows nationwide, with the Tamil version leading the charge, contributing nearly ₹12 crore net and recording an overall occupancy of 54%. Evening and night screenings were particularly popular, with night occupancy in Tamil regions exceeding 75%. The Telugu dubbed version also performed well, bringing in ₹2.40 crore net from 1,443 shows. Tamil Nadu emerged as the strongest market, generating around ₹10.50 crore in gross collections. Despite the film's strong performance, it faced hurdles, including cancelled morning shows due to financial disputes between producers and financiers. Director RJ Balaji reassured fans about the team's efforts to resolve these issues, emphasizing the film's challenging journey over the past 32 months. Karuppu marks a significant reunion for Suriya and Trisha, who last appeared together in the 2005 film Aaru.
