Overview
- The film opened on October 2 with Rs 2.35 crore India nett on Friday, dropped to Rs 1.50 crore on Saturday, and remained flat at Rs 1.50 crore on Sunday, taking the three‑day India nett to Rs 5.35 crore.
- Trade tracker Sacnilk reported 23.6% overall occupancy on Sunday with 149,651 footfalls that day and a cumulative weekend footfall of about 515,512.
- The Tamil version generated the largest share of receipts (Rs 95 lakh on Day 3) while the Telugu release underperformed (Rs 55 lakh on Day 3) and an unnamed distributor said Telugu‑state returns were 'underwhelming' at roughly Rs 80 lakh.
- Some outlets list the film’s three‑day India gross as Rs 6.10 crore while others report Rs 6.3 crore, and Koimoi called Sigma the lowest opening weekend for a Kollywood directorial debut in 2026.
- Jason Sanjay’s family pedigree drove early curiosity but the weak start increases the film’s reliance on weekday holds and word‑of‑mouth to avoid a poor theatrical run.
