NSE IPO 2026: DRHP dates, sellers, and OFS size

Why NSE’s IPO filing matters now

India’s largest stock exchange, the National Stock Exchange (NSE), is expected to take a key step toward listing by filing its draft red herring prospectus (DRHP) with the Securities and Exchange Board of India (SEBI). Multiple reports and sources cited across publications indicate the filing could happen in June 2026, bringing the long-running listing plan closer to execution. The proposed public issue is described as a pure offer for sale (OFS), meaning NSE itself is not expected to receive any proceeds from the IPO. Instead, existing shareholders will sell part of their holdings.

The development is closely watched because it involves some of the largest domestic and global financial investors, and because NSE’s listing has been anticipated for years. The DRHP filing is also important because it typically brings clarity on the offer structure, the list of selling shareholders, risk factors, and the operating and financial disclosures that investors track.

DRHP filing window: early June to mid-June signals

The timeline has been described in different ways across reports, but the common point is a June filing. One set of sources indicated NSE may file the DRHP on June 15 or June 16. Another report cited a broader window between June 5 and June 15. There were also mentions that the exchange and its bankers planned to proceed by the end of the first week or in the early part of the second week of June.

CNBC-TV18 reported that NSE initially targeted a June 14 deadline, but the filing could happen as early as the beginning of June. Separately, sources cited by Business Today pointed to the filing happening “this week” and even referenced Wednesday as a potential moment when the IPO moves a step closer. Taken together, the reports suggest a DRHP submission is expected in June 2026, with the timing clustered around early-to-mid June.

Pure OFS structure: no fresh issue for NSE

Across the reports, the IPO is repeatedly described as entirely an offer for sale, with no fresh issue component. This means NSE is not expected to raise new capital from the offering, and the proceeds would go to selling shareholders. One report also referenced NSE’s board approving an IPO through an OFS on 6 February 2026, following SEBI’s no-objection clearance.

The OFS-only structure matters for investors because it positions the IPO primarily as a liquidity event for current owners rather than a capital-raising exercise for the exchange. In such issues, market participants closely track who is selling, how much is being offered, and whether large shareholders are reducing exposure or choosing to stay invested.

Who may sell: PSUs and global investors in focus

A broad group of shareholders have been cited as potential sellers. Reports said over a dozen institutional and corporate investors are expected to sell shares. Names mentioned include State Bank of India (SBI), Bank of Baroda (BoB), Stock Holding Corporation of India (SHCIL), Indian Bank, The New India Assurance Co. Ltd, The Oriental Insurance Co., General Insurance Corporation of India (GIC), National Insurance Co. Ltd, and ICICI Lombard.

On the global and private capital side, potential sellers cited include CPPIB (Canada Pension Plan Investment Board), Temasek (including references to Temasek affiliate Aranda Investments), and ChrysCapital. Other institutional names mentioned in the wider selling group include Morgan Stanley and GS Strategic Investments.

In one account, some top domestic shareholders were said to plan to sell around 10% each of their shareholding. CNBC-TV18 also reported that institutional participation is high, with most offering near 10% of their existing stake.

LIC’s stance: may hold, even as others sell

Life Insurance Corporation of India (LIC), described as the biggest investor in some reports, may not sell in the IPO, according to people aware of the matter cited in coverage. At the same time, other reporting mentioned LIC among those being nudged to participate. The shareholder data quoted across reports also varies: one Hindi-language excerpt listed LIC at 10.72% and SBI plus SBI Capital Markets at around 7.5%. A Fortune India account described LIC at 10.7%, while another cited figure described LIC at 12.5%.

Given the differences, the consistent point is that LIC is among the largest shareholders and its decision on participation is closely watched because it can influence how the sale is perceived and how much stock ultimately comes to market.

Expected dilution and offered stake: 4% to 5% range cited

Several reports pointed to modest dilution at the company level. CNBC-TV18 indicated NSE is expected to dilute around 4% to 5% equity through the proposed IPO. Another snippet referred to dilution of around 4% to 4.5%. Separately, it was reported that a little more than 5% of NSE’s shareholding has been offered for sale in the IPO, driven by institutional shareholder participation.

The same coverage noted retail shareholder participation is negligible, with fewer than 500 retail shareholders offering shares for sale. This helps explain why the sale appears geared toward institutional and strategic shareholders.

Deal sizing and timing: Rs 20,000 crore cited, listing targeted by December

One report described the “National Stock Exchange’s Rs 20,000 crore IPO” as nearing launch with a June DRHP filing expected. Another estimate put the IPO size at around Rs 22,000 to Rs 23,000 crore (converted from Rs 220-230 billion), depending on valuation and stake sale.

On timelines beyond filing, there is also a reported target for listing before December 2026. While a filing does not guarantee immediate approval or listing, it anchors the process around a formal SEBI review.

Eligibility conditions and EOI deadline referenced

A specific eligibility condition was mentioned in one report: the issue would allow only shareholders who held fully paid-up NSE shares since June 2025 to sell. The same report said eligible investors must file expressions of interest (EOIs) by April 27, 2026.

These details, if reflected in the final DRHP, would shape which shareholders can participate in the OFS and how much stock could realistically be offered.

Key facts at a glance

Market impact: what investors will watch

For markets, the immediate impact of a DRHP filing is usually informational rather than operational. Investors and intermediaries track the seller list, the proportion of shares actually offered, and how concentrated selling is among public sector institutions versus global investors. The OFS-only nature also means pricing and allocation dynamics will be shaped by supply from existing holders, not by any primary capital requirement for NSE.

Another factor is the reported stake holdings and selling intentions among public sector and institutional shareholders. SBI and its subsidiary SBI Capital Markets were reported to own around a 7.5% stake together, and SBI was also described elsewhere as holding 3.23% with SBI Capital Markets at 4.33%. If large holders sell portions of their stakes, that may influence the free float expected post listing.

Analysis: why this filing is a critical milestone

The consistent thread across the reports is that NSE and its bankers are moving toward a June DRHP filing after prior delays, with the board having approved an IPO through OFS on 6 February 2026. That makes the coming filing a key process step, because it formalises the offer in SEBI’s public domain and sets the stage for regulatory review.

The coverage also highlights a sell-side skew toward institutions. With retail participation described as negligible and institutional participation described as high, the eventual offer size and liquidity are likely to hinge on how much the large domestic and global shareholders choose to tender. The mention that a little more than 5% of shareholding has been offered for sale provides one quantitative snapshot of how the OFS pool could shape up.

What happens next

The next confirmed milestone, based on the reporting, is the DRHP filing with SEBI in June 2026. After the filing, the process typically moves through regulatory review and updates to offer documents, which would clarify final selling shareholders, the exact OFS size, and the timeline for the listing that some reports expect before December 2026.
