IIM waitlist movement for the CAT 2025 cycle (2026-28 batch) is now in full swing. IIM Ahmedabad released its final admission offers on April 13, 2026, IIM Bangalore on April 20, IIM Calcutta on April 24, and most JAP IIMs (Lucknow, Kozhikode, Indore, Raipur, Trichy, Shillong) on May 7, 2026. If you are sitting on a waitlist at any IIM, the next eight weeks — late May through mid-July — are the most consequential period of the admission cycle. This guide explains exactly how movement works, what realistic conversion odds look like, and the exact playbook to follow if your name is on a waitlist.
The CAT 2025 final-offer timeline at a glance
- April 13, 2026 — IIM Ahmedabad final offers released (iima.ac.in).
- April 20, 2026 — IIM Bangalore final results.

- May 7, 2026 — IIM Lucknow, IIM Indore, IIM Kozhikode, IIM Raipur and other JAP IIMs released final results together.
- May 2026 onward — Round 1 acceptances close, waitlist conversion emails begin.
Why IIM waitlists move at all
A single CAT 2025 high-percentiler often holds offers from three or four IIMs simultaneously — say, IIM-A, IIM-B, IIM-L and IIM-I. When that candidate accepts IIM-A, the seats they vacate at B, L and I move down each of those waitlists. This cascade is the engine of waitlist movement. The higher you sit in the IIM pecking order, the more candidates above you are likely to drop off — which is why lower-tier IIMs (Lucknow, Kozhikode, Indore) historically see the largest general-category waitlist movement, often 300-600+ places between May and July.
Expected May-July 2026 movement: realistic numbers
| IIM | Typical Gen WL movement (R1 to R3) | Best-case conversion range |
|---|---|---|
| IIM Ahmedabad | 20-60 places | WL 1-40 likely |
| IIM Bangalore | 30-100 places | WL 1-70 likely |
| IIM Calcutta | 60-150 places | WL 1-120 likely |
| IIM Lucknow | 300-600 places | WL 1-500 likely |
| IIM Kozhikode | 400-700 places | WL 1-600 likely |
| IIM Indore | 300-600 places | WL 1-500 likely |
Caveat: these are historical bands, not guarantees. Movement varies year-on-year based on overlap with ISB PGP, IIM-A/B/C acceptance behaviour, and the FMS / SPJIMR / MDI converts in the same talent pool.
How IIM final composite scores work
Most IIMs build the final merit list using a composite of:
- CAT 2025 percentile — ~25-33%
- WAT (Written Ability Test) — ~10-15%
- Personal Interview — ~25-30%
- Academic profile (Class 10, 12, graduation) — ~15-20%
- Work experience + diversity — ~15-25%
This is why two candidates with identical CAT percentiles can land on opposite ends of a waitlist — academic consistency and WAT-PI strongly influence final position.
The waitlist playbook: what to do this week
- Accept your best confirmed offer. Pay the fee. This is non-negotiable — never sit waitlist-only with no confirmed seat.
- Keep higher-preference waitlist slots active. Most IIMs charge a nominal “waitlist confirmation fee” (~₹2,000-5,000). Pay it if the IIM is genuinely higher in your preference order.
- Track movement weekly. Check the official admission portal of each IIM you are waitlisted at — Wednesdays and Fridays are common update days.
- Watch for conversion emails. Once converted, you typically have 5-7 days to accept and pay fees. Miss the deadline, lose the seat.
- Have a Plan B ready. If you are waitlisted at IIM-L #400 in general and have an FMS / SPJIMR / MDI offer, do the math on placements, fees and ROI before assuming you’ll convert.
What about reserved-category waitlists?
OBC-NC and SC/ST waitlists move differently — they often move further at top IIMs (A, B, C) because the candidate pool is smaller, and stagnate at lower IIMs because most reserved candidates accept their top IIM offer. Check your specific IIM’s category-wise waitlist numbers via the official portal, not via secondary sources.
Common waitlist mistakes
- Declining a confirmed B-school seat too early “because IIM-L will surely convert” — it might not.
- Not tracking the official portal because “they’ll email me” — many IIMs publish movement on the portal first, email later.
- Missing the acceptance deadline after conversion because the email landed in spam.
- Comparing your WL position to last year’s conversion numbers without adjusting for cohort size changes.
Looking ahead: CAT 2026 cycle for next year’s aspirants
If you missed the cut this year and are gearing up for CAT 2026 (exam on November 29, 2026, conducted by IIM Indore), the conversion lesson is clear: raw CAT percentile alone does not guarantee an IIM seat. Academic consistency, work-experience signal and WAT-PI prep all compound. Start now. Read our companion guide on the upcoming CAT 2026 notification for the full timeline.

Frequently asked questions
How long does IIM waitlist movement continue?
The bulk of movement is done by end of July 2026. Marginal movement at some IIMs continues into early August before the academic year begins.
Will my IIM Lucknow waitlist at #400 convert?
Historically yes, but this is not guaranteed. IIM-L general-category waitlists have moved 400-600 places in past years. Track the official portal weekly.
Can I accept seats at two IIMs simultaneously?
No. Once you accept and pay fees at one IIM, you must withdraw from others. Holding multiple seats is against the IIMs’ admission policy.
What if I get converted but the deadline passes?
The seat is forfeited and offered to the next candidate. Always check your admission portal and registered email daily during May-July.
