NSE IPO: OFS structure, valuation cues, key risks

NSE files DRHP, ending a long wait

National Stock Exchange of India Ltd has taken the first formal step towards a public listing by filing its draft red herring prospectus (DRHP) with SEBI. The DRHP is dated June 17, 2026, and social media discussion has quickly shifted from “when” to “how big” and “at what price”. Posts also frame the IPO as a milestone because NSE sits at the centre of India’s capital markets ecosystem. The filing is being read as the culmination of a process that began in December 2016, when NSE filed an earlier DRHP for a Rs 10,000-crore issue. Several commentators link the renewed momentum to regulatory clarity after the long-running co-location matter, which some analysts say removed a key overhang. Market chatter also notes that NSE’s IPO committee has hired 20 lead managers, signalling operational readiness. The most repeated investor takeaway is structural: this listing is designed primarily as a shareholder monetisation event, not a capital raise for NSE.

100% OFS: what investors should know upfront

The NSE IPO is structured as a 100% book-built Offer for Sale (OFS) with no fresh issue component. Existing shareholders can sell up to 148,905,525 equity shares (about 14.89 crore), with face value Re 1 each. Multiple posts highlight that the OFS represents close to 6% of NSE’s paid-up equity capital, meaning the float on offer is relatively small versus the company’s overall size. Because it is an OFS, NSE will not receive any proceeds from the issue, and the entire amount will go to the selling shareholders. This distinction matters for investors assessing what changes in the business after listing, since there is no new equity capital being injected through the IPO. Another frequently cited point is that NSE shares will be listed on the BSE mainboard, mirroring the arrangement under which BSE’s own shares are listed on NSE. The offer is described as being made under Regulation 45 of the SECC Regulations read with Rule 19(2)(b) of SCRR and Regulation 31 of SEBI ICDR Regulations. Social media commentary treats the “listing on rival exchange” angle as symbolic, but also practical within the regulatory framework.

Who is selling: PSU holders and global investors

Online discussion names a wide set of selling shareholders, including SBI, Morgan Stanley, Temasek, and CPPIB. There is also repeated mention of public sector entities monetising part of their holdings, including State Bank of India, Bank of Baroda, Stock Holding Corporation, GIC, New India Assurance, National Insurance Company, and United Insurance Company. The presence of both domestic financial institutions and global investors is being interpreted as evidence of long-term institutional ownership in the exchange. At the same time, investors on forums are focusing on what an OFS-heavy shareholder mix implies for supply and post-listing liquidity. Some posts highlight that the issue size has been fixed at 6% of paid-up capital, which sets a ceiling on how much exits can happen through this single transaction. That constraint may reduce near-term stake-sale overhang, but it does not remove the possibility of future sell-downs if regulations and market conditions permit. The key point remains that the sellers, not NSE, are the beneficiaries of IPO proceeds. For retail and long-only investors, this shifts attention to business fundamentals and valuation discipline rather than IPO-funded expansion plans.

Operating performance: FY26 slowdown becomes the headline

Alongside the listing news, the most discussed fundamental datapoint is NSE’s FY26 performance versus FY25. Revenue from operations fell 3% year-on-year to Rs 16,601 crore in 2025-26, from Rs 17,141 crore in FY25. This comes after a strong FY25, when revenue had risen 16% on stronger trading activity. Social media links the FY26 dip to the market regulator’s derivatives reforms, which slowed trading activity and weakened volumes across cash, equity futures, and options segments. The framing is not that NSE is losing relevance, but that near-term revenue sensitivity to trading intensity has become more visible. Some posts call this a “core operating performance” wobble after years of strong growth narrative. For an exchange business that investors often treat as an infrastructure compounder, even a single-year decline is being used to anchor valuation debate. The implication is that investors may not be willing to extrapolate peak-cycle trading activity into future earnings multiples without a margin of safety.

Cost mix: technology spend takes one-fifth of expenses

Another datapoint circulating widely is expense composition, particularly technology spend. Discussions cite that technology spending made up one-fifth of NSE’s total FY26 expenses, even as revenue growth slowed. The market is reading this in two ways, depending on the poster. One camp sees the higher tech spend share as supportive of resilience, capacity, and system robustness for an exchange that runs critical market infrastructure. The other camp treats it as a margin pressure risk if trading activity stays softer for longer. The context does not provide absolute expense numbers, but the 20% share is enough to keep technology investment at the centre of the cost narrative. This also ties into investor memory of earlier governance and market-structure controversies, where surveillance, latency, and systems have historically been hot-button topics. With listing closer, the expectation on disclosure quality and ongoing systems investment is likely to rise. For now, the factual takeaway is simple: tech is a meaningful cost line in FY26, at a time when topline growth has slowed.

Size and structure: why it could be India’s biggest IPO

Several posts describe the NSE IPO as potentially India’s biggest-ever public offering, based on issue-size estimates. One widely shared estimate pegs the public issue at around Rs 29,780 crore, while other references cluster in the Rs 25,000-30,000 crore range. These figures are presented as estimates rather than final numbers, because the IPO is still at the DRHP stage and a price band is not yet announced. In comparisons circulating online, an issue of about Rs 30,000 crore would exceed Hyundai Motor India’s roughly Rs 27,859 crore IPO and LIC’s Rs 20,557 crore offer, both cited as benchmarks. Separately, posts mention a valuation expectation of over Rs 5 lakh crore, with unlisted-market pricing often used as an indicative anchor. There is also discussion that only about 6% of paid-up capital is being offered, reinforcing that a large valuation can coexist with a relatively small percentage of shares sold. Investors should read “biggest IPO” claims as conditional on final pricing and allocation, but the scale narrative is clearly driving attention.

Valuation cues: unlisted prices and peer multiple math

Valuation is where the conversation becomes most fragmented, with different anchors used across threads. One analyst quote shared on social media says NSE trades around Rs 1,950-2,170 in the unlisted market and around 45x FY26 earnings, calling it rich but below BSE at around 70x and MCX at around 80x. Another widely circulated peer-multiple exercise takes BSE Limited’s P/E of 66.67x and applies it to FY2026 EPS of Rs 41.62 to imply a price of about Rs 2,774 per share. That same exercise implies a market cap of about Rs 6.87 trillion (about US$12.6 billion at Rs 94.65 per US dollar), positioning NSE among India’s largest listed companies if achieved. Separately, social posts cite unlisted trading around Rs 1,975 per share and sketch upside scenarios using assumed listing multiples, but those are opinions rather than disclosed IPO guidance. The consistent theme is that investors are benchmarking NSE as an exchange infrastructure business with premium multiples, while also questioning how much premium is justified after FY26’s revenue decline. Until the price band is out, the market is likely to keep triangulating between unlisted trades, listed peers, and FY26 earnings.

IPO mechanics and timing: what is known, what is not

At this stage, the most concrete information is the filing itself and the OFS structure. The DRHP has been filed with SEBI, and the listing venue is BSE mainboard. Commentators repeatedly note there is no fresh issue, so NSE receives zero proceeds, and this matters for interpreting the IPO’s purpose. On market microstructure, some posts also emphasise that NSE shares have not had a prior formal public market, which is why unlisted trading references are being watched closely. A frequently asked question in forums is about grey market premium (GMP), and the repeated answer is that a widely tracked GMP typically emerges only after the price band and subscription window are announced, so there is no active GMP yet at the DRHP stage. There is also a social media timeline expectation that listing could be later in 2026, with one post suggesting December 2026, but it remains an expectation rather than a confirmed date in the shared context. For investors, the practical next steps to watch are the SEBI review process, any updates to the offer details, and final pricing disclosures. Until then, most valuation debate is best treated as indicative.

Key numbers mentioned online (from DRHP coverage)

What the social conversation gets right, and what to treat cautiously

The strongest factual consensus is on structure: this is an OFS-only IPO and NSE will not raise new capital through it. The second clear consensus is on the FY26 revenue slowdown and the link being made to derivatives reforms and softer trading activity across key segments. The third is that the listing is planned on BSE, which is unusual in optics but consistent with the arrangement between the two exchanges. Where investors should be more cautious is on “largest IPO” certainty, because issue size depends on the eventual price band and demand at book-building. Similarly, implied valuation outputs based on peer multiples are useful reference points, but they are not official pricing signals. Unlisted prices give an indicative sentiment read, but they do not replicate listed-market liquidity or price discovery. Finally, projections of upside based on assumed future PAT growth or assumed listing multiples are opinions, not DRHP facts. For now, the clearest analytical frame from the available context is to balance NSE’s dominant position and infrastructure-like profile against near-term trading-linked cyclicality and valuation expectations.
