CSAB 2026 All India Quota Vacant Seats: Real Data

CSAB's official "Tentative Seat Vacancy" document lists every institute-program-quota-category row with at least one unfilled seat. Summing every row tagged All India (AI) quota gives a headline figure of 9,816 vacant seats — the largest single quota block in the entire CSAB 2026 vacancy pool, ahead of Home State quota (2,766) and Other State quota (2,683) combined.

All India quota is used by all IIITs — since IIITs don't split seats by home state at all, every IIIT seat is effectively AI quota, allotted purely on national merit regardless of a candidate's domicile. GFTIs also use AI quota, specifically for candidates applying from outside that GFTI's home state, alongside their separate Home State and Other State allocations. Of the 9,816 vacant AI-quota seats, GFTIs hold 6,188 (63%) and IIITs hold 3,628 (37%).

Because AI quota draws applicants from the entire country rather than one state, it carries no domicile restriction — any CSAB-eligible candidate can apply. That breadth is also why it has the largest vacancy pool: it spans a wider set of institute-branch combinations than a state-restricted quota ever could, so a similar proportional vacancy rate compounds into a much larger absolute number.

At IIITs, there is no home-state or other-state split — every single seat, across every branch and category, is allotted under All India quota. This means the 3,628 vacant IIIT seats shown here represent the complete IIIT vacancy picture for CSAB 2026, not a subset. If you're targeting an IIIT in CSAB Special Rounds, AI quota vacancy data is the only figure that matters.

At GFTIs, seats are typically split three ways: Home State quota (for candidates domiciled in that GFTI's state), Other State quota (for candidates from other states, capped per GFTI), and All India quota (for candidates from anywhere, without a per-state cap in the same way OS quota works). The 6,188 vacant GFTI AI-quota seats sit alongside the separate 555 Home State and 202 Other State GFTI vacancies tracked elsewhere on this site — together, these three pools make up a GFTI's total vacancy.

For out-of-state candidates without a domicile advantage at a particular NIT or GFTI, AI quota is usually the most relevant quota to track, since it's open to everyone nationally and, at 9,816 vacant seats, currently represents the largest open opportunity pool in the CSAB Special Round vacancy data.
