CSAB 2026 Seat Matrix – Available Seats in NITs, IIITs & GFTIs
Understand how CSAB seats are formed, which institutes participate, and what to expect in 2026
How CSAB 2026 Seat Matrix is Formed
The CSAB 2026 seat matrix is not a fixed pre-determined set of seats. It is formed dynamically after JoSAA 2026 Round 5 concludes (July 16, 2026), based on two sources:
- Vacated seats from JoSAA 2026: In every JoSAA round, some candidates who receive allotment do not report to their institutes. These seats become "vacated" and are transferred to CSAB. The number of vacated seats varies by institute and branch, but typically runs into the thousands across all NITs, IIITs, and GFTIs.
- Supernumerary NEUT seats: CSAB creates additional seats (over and above the sanctioned intake) specifically for candidates from North Eastern states and Union Territories. These are typically 2–5 seats per institute and are only available to NEUT-eligible candidates.
Once the seat matrix is finalized, it is published on the CSAB portal at the start of registration. Candidates can view available seats by institute, branch, and category before filling their choice list.
