What's actually confirmed
IIM Indore, this year's conducting institute for CAT, opened registration on 3 August 2026 and set 15 September 2026, 5:00 PM IST as the closing time on the official portal, iimcat.ac.in. Candidates who have not yet submitted and paid for their application must complete both steps before the portal closes today; a saved but unpaid form does not count as a completed registration.
What comes next
Once registration closes, the next fixed date on IIM Indore's published calendar is 4 November 2026, when admit cards become available for download from the same portal. CAT 2026 itself is a single-day exam on Sunday, 29 November 2026, run as a computer-based test in three sessions across roughly 170 cities nationwide — unchanged from the schedule announced when the form opened in August.
If you're reading this before 5 PM today
Candidates still completing their form should keep a copy of the payment confirmation and downloaded application form, since IIM Indore has repeatedly flagged iimcat.ac.in as the only official CAT website and warned against unofficial portals claiming to process late applications. Some past CAT cycles have seen registration deadlines extended by a few days, but there is no official word from IIM Indore on any extension for 2026 as of this update; candidates should treat today's 5 PM deadline as final unless the change appears directly on iimcat.ac.in.
