TL;DR
Swiggy listed on the NSE/BSE on November 13, 2024. Less than five months later, it was added to the Nifty Next 50 effective March 28, 2025, after joining the Nifty 100 during the semi-annual index review. This rapid progression tells pre-IPO investors three things: (1) quality private companies can transition to large-cap club quickly, (2) early index inclusion can unlock passive fund demand and liquidity, and (3) robust pre-IPO positioning—including understanding lock-ins and valuation bands—can materially affect outcomes post listing.

1) Why Swiggy’s “fast entry” is a big signal
Speed matters. Swiggy’s IPO closed in early November 2024 and the stock listed on Nov 13, 2024. By the March 2025 semi-annual review, NSE Indices confirmed Swiggy’s inclusion in the Nifty Next 50 (NN50) from the close of March 27, 2025—a transition of roughly 4.5 months post listing. For a fresh listing to reach NN50 that quickly, it needs to meet the Nifty 100 criteria first (NN50 = Nifty 100 minus Nifty 50) and clear liquidity/size thresholds in time for the scheduled review. That’s precisely what happened.
Why this is important for pre-IPO investors:
- Validation & signalling: Joining NN50 via Nifty 100 suggests strong free-float market cap and trading metrics—both are signals public markets take seriously.
- Institutional discovery: Being in Nifty 100/Next 50 puts the stock squarely on screens of passive and quasi-passive mandates that mirror or tilt toward these indices.
- Liquidity step-change: Index additions can draw index funds/ETFs that track NN50, adding an incremental buyer base. While exact flows vary by AUM, India’s passive ecosystem has been expanding rapidly, with strong growth in 2025.
2) From unlisted to index-ready: the timeline that mattered
- Nov 2024: Swiggy lists on the NSE/BSE on Nov 13, 2024.
- Feb 21, 2025: NSE Indices’ Index Maintenance Sub-Committee announces semi-annual replacements; Swiggy is added to Nifty 100 and consequently Nifty Next 50. Effective March 28, 2025 (close of March 27).
- Mechanics: Per NSE methodology, Nifty Next 50 constituents are the Nifty 100 members not in Nifty 50; additions depend on rank by full market cap, liquidity screens, and (for Nifty 100) thresholds like 1.5× size versus the smallest constituent and either F&O availability or sufficiently high turnover.
So, what made it “fast”? Swiggy cleared the Nifty 100 bar within the very first eligible semi-annual window after listing—allowing NN50 inclusion at the same cut-off.
3) What changes when a stock enters the Nifty Next 50
a) Passive demand “on tap”
India’s passive AUM has expanded in recent years, and multiple funds track the Nifty Next 50—via ETFs and index funds. Inclusion typically triggers portfolio realignments by these vehicles around the effective date, creating a one-off demand pulse and, more importantly, ongoing baseline demand as fresh flows come in. (Magnitude varies by the total AUM tracking NN50 and by fund-level flows.)
b) Coverage & liquidity
NN50 stocks often see wider institutional coverage, tighter spreads, and deeper order books over time, especially if they graduate to F&O eligibility (subject to SEBI/NSE norms). While index inclusion doesn’t guarantee performance, it raises visibility and reduces friction for large pools of capital.
c) Pathway to Nifty 50
NN50 is the staging area for potential future Nifty 50 entrants. Movement depends on sustained free-float market cap, liquidity, and the semi-annual rank relative to current Nifty 50 members. Some NN50 constituents graduate; others don’t—but the optionality premium is real.
4) The SEBI lock-in clock: reading supply overhangs
For pre-IPO investors, a key calendar is the lock-in release:
- Non-promoter pre-IPO shareholders: Typically 6 months lock-in from allotment (i.e., post listing, the 6-month clock matters). A sizeable unlock can create incremental supply, affecting near-term price action.
- Minimum Promoter Contribution (MPC): 20% of post-issue capital usually locked for 18 months (reduced from 3 years in 2021), with caveats if fresh proceeds are majority earmarked for capex (can require 3 years). Promoter holding above MPC: generally 6 months.
- Anchors: A staggered 30/90-day unlock structure exists for anchor investors in book-built IPOs.
Why this matters: If index inclusion (buy-side demand) coincides with lock-in expiries (sell-side supply), the net effect on the stock can swing either way. Smart pre-IPO investors map both index dates and unlock dates to gauge near-term balance.
5) Lessons for pre-IPO investors (actionable)
- Underwrite the “indexability” early
When evaluating unlisted shares, don’t just model TAM, growth, and unit economics—score index readiness post-listing: - Could the issuer enter Nifty 100 within the first review cycle?
- Does free-float sizing and turnover look adequate at IPO pricing?
- Is F&O eligibility plausible (helps liquidity screens)?
Swiggy’s case shows that fast Nifty 100 → Next 50 pathways are possible when these boxes tick. - Track semi-annual review windows
NSE rebalances in March and September (based on data ended January and July). Position sizing into/around these windows can be crucial for both pre-IPO exit planning and post-listing adds. - Map unlocks vs. passive flows
Build a calendar of: - Lock-in releases (6-month, 18-month)
- Index effective dates (implementation usually at close on the day before the effective date)
- ETF/index fund rebalancing practices
This triangulation helps anticipate short-term supply/demand. - Expect dispersion
Index inclusion alone doesn’t ensure price appreciation. Managerial execution, competitive intensity, sector cycles, and flows into passive products all matter. Treat inclusion as one input in a broader mosaic. - Pre-IPO valuation discipline
A quick march to NN50 can de-risk liquidity, but it doesn’t immunize against multiple compression if growth under-delivers. Leave a margin of safety in pre-IPO pricing bands.

7) FAQs (for pre-IPO & unlisted share investors)
Q1) How soon after listing can a company enter Nifty Next 50?
There’s no fixed “X months” rule. Nifty Next 50 is simply the set of Nifty 100 constituents not in Nifty 50. If a newly listed company meets Nifty 100 criteria by the next semi-annual review (size and liquidity thresholds), it can be added, which in turn makes it eligible for NN50 at the same review. Swiggy’s inclusion became effective March 28, 2025, roughly 4.5 months after listing.
Q2) Does Nifty Next 50 inclusion guarantee price performance?
No. It supports liquidity and introduces passive demand, but performance still depends on fundamentals, flows, and market conditions.
Q3) What are the standard SEBI lock-ins I should track as a pre-IPO investor?
- Non-promoter pre-IPO: usually 6 months.
- Promoter MPC (20%): typically 18 months (3 years if most fresh proceeds are capex).
- Promoter holding above MPC: generally 6 months.
- Anchors: 30/90-day stagger. Always verify the final prospectus for specifics.
Q4) How big are the flows from NN50 indexers?
AUM varies across ETFs and index funds; several large funds track NN50 and re-align holdings at rebalance. The broader passive AUM base in India has grown meaningfully, which is supportive—but exact stock-level flows depend on each fund’s AUM on the date.
Q5) Where can I learn more about the exact index rules?
NSE Indices publishes methodology documents and press releases for each rebalance and inclusion/exclusion list.
8) Conclusion & Next Steps
Swiggy’s swift journey—listing in Nov 2024, Nifty 100 & Nifty Next 50 inclusion by Mar 2025—is a case study in how top private companies can become index-relevant rapidly. For pre-IPO investors, this underscores the value of:
- diligencing index readiness (size/liquidity) before the IPO,
- aligning positions around rebalance windows, and
- mapping lock-in releases against passive inflows.
If you want to source the next Swiggy-like opportunity before the crowd, or exit efficiently around these milestones, UnlistedCorner is built for you—from vendor listing to investor execution—with the research, compliance help, and market access you need.
