Quick Verdict
On the closing-rank evidence available, IIT Bombay is the tougher admit: its JoSAA 2026 closing rank tightened to 7360, while IIT Guwahati's closing rank rose to 10732, one of the largest year-on-year increases of any IIT (Careers360). That gap means a lower rank clears a seat at Bombay than at Guwahati, at least at the margin where each institute's least-competitive branch sits.
Snapshot

Detailed Analysis
The clearest branch-cutoff signal in the data is the JoSAA "last closing rank" -- the rank of the final seat filled in Round 2, open category, in 2026. For IIT Bombay this fell from 7847 in 2025 to 7360 in 2026, and it corresponds to the institute's Chemistry (4-Year Bachelor of Science) programme -- typically one of the least sought-after seats on campus (Careers360). A tightening closing rank, even in the least-competitive branch, points to Bombay pulling in stronger applicants across the board rather than easing up anywhere.
IIT Guwahati moved the opposite direction. Its last closing rank rose from 9243 to 10732 -- a jump of 1489 ranks, the fourth-largest increase recorded among all 23 IITs in the 2026 Round 2 data -- and that closing rank belongs to Biosciences and Bioengineering (Careers360). In practice, that means the weakest seat at Guwahati became noticeably easier to clear year over year, even as Bombay's equivalent seat became harder.
Institutional context helps explain some of the gap. IIT Bombay ranks #3 overall in NIRF 2025 with a score of 81.62, while IIT Guwahati sits at #11 overall (score 67.67) though it holds a respectable #8 specifically in the Engineering category (NIRF; KollegeApply). Guwahati -- a government-owned institute established in 1994 with a 285-hectare campus in Assam -- is younger and smaller in overall reputation than Bombay, which likely feeds into its comparatively softer closing ranks (KollegeApply).
One important caveat: the sourced facts do not include branch-by-branch, category-wise (General/OBC/SC/ST/EWS) rank tables for individual engineering branches such as Computer Science, Electrical, or Mechanical at either institute. The only branch-linked numbers available are each institute's single least-competitive seat. So while the aggregate trend clearly favors Bombay as the harder admit, a reader specifically comparing, say, CSE-to-CSE cutoffs between the two cannot be given precise figures here -- that data simply isn't in the researched facts. Separately, IIT Guwahati released its JEE Advanced 2026 cutoff for the first round of BTech admissions (Shiksha), and it also published GATE 2026 results and branch-wise M.Tech qualifying/admission cutoffs on March 19, 2026, distinguishing the "GATE qualified" threshold from the actual admission cutoff (Jagran Josh) -- but no comparable GATE cutoff figures for IIT Bombay appear in the sourced facts, so that axis can't be compared here either.
Verdict
IIT Bombay wins on branch cutoffs: its overall closing rank tightened in 2026 even at its softest branch, and its far stronger NIRF standing (#3 vs #11 overall) reinforces that it pulls tougher applicants institute-wide (Careers360; NIRF). IIT Guwahati is the runner-up here, but it's the sensible pick if your rank specifically clears its 2026 closing threshold (10732) and not Bombay's (7360) -- in that scenario, a seat at Guwahati, in a branch like Biosciences and Bioengineering, is the realistic option over no IIT seat at all.
Frequently Asked Questions
Q: Which IIT has the tougher closing rank overall, Bombay or Guwahati?
IIT Bombay: its 2026 closing rank of 7360 is much tighter than Guwahati's 10732 (Careers360).
Q: Did IIT Guwahati's cutoff get easier in 2026?
Yes -- it rose by 1489 ranks year over year, the 4th-largest increase among all IITs (Careers360).
Q: What does "closing rank" mean in this comparison?
It's the rank of the last seat filled in JoSAA Round 2 2026, open category (Careers360).
Q: Which branch had the last closing rank at each institute in 2026?
Chemistry (4-Year BSc) at IIT Bombay and Biosciences and Bioengineering at IIT Guwahati (Careers360).
Q: Is there branch-wise data comparing CSE, Electrical, or Mechanical cutoffs specifically?
No -- the sourced facts only give each institute's single least-competitive branch closing rank, not a full per-branch, per-category table.
Q: How do the two institutes compare in NIRF 2025?
IIT Bombay is #3 overall (score 81.62); IIT Guwahati is #11 overall (score 67.67) and #8 in Engineering (NIRF; KollegeApply).
Q: When was the JEE Advanced 2026 cutoff released for IIT Guwahati?
For the first round of BTech admissions in 2026 (Shiksha).
Q: Does GATE (M.Tech) cutoff data show the same gap?
Not comparably -- the sourced facts cover only IIT Guwahati's GATE 2026 results and cutoff announcement timeline, with no matching IIT Bombay GATE figures to compare against (Jagran Josh).
