NSE IPO DRHP filed: key details of 6% OFS

NSE files DRHP after a long wait

National Stock Exchange of India (NSE) has filed its draft red herring prospectus (DRHP) for its IPO. Social media discussion focused on the filing as the biggest step in a process delayed for years. Posts cited the DRHP as a 607-page document filed with SEBI and the BSE on Wednesday, June 17, 2026. The proposed listing is planned on BSE, mirroring how BSE is listed on NSE. The IPO is structured as an offer for sale, so it is about shareholder exits rather than raising fresh capital. Several market participants online framed it as a milestone because the listing plan had remained stalled for nearly a decade. The delay has been widely linked to regulatory concerns, especially the co-location controversy. The filing means SEBI now formally begins its review process.

What the DRHP says about the offer structure

The issue is entirely an offer for sale (OFS) by existing shareholders. The DRHP notes a face value of Rs 1 per equity share. The OFS size is up to 148,905,525 equity shares, which is described as nearly 6 percent of NSE’s paid-up capital. Because it is a pure OFS, there is no fresh issue of shares. That point mattered in online debate because it changes how investors read the “use of proceeds”. In an OFS, proceeds typically go to selling shareholders, not the company. Social commentary also highlighted that the OFS percentage is well above SEBI’s minimum public float requirement for very large companies, as cited in some reports. The headline takeaway from the draft is that the company is moving from “expected” to “filed”.

Listing venue: why NSE plans to list on BSE

The DRHP filing notes that NSE shares will be listed on BSE. This detail became a major talking point because it is unusual for a stock exchange to list on its closest peer. Online posts drew a simple parallel, noting that BSE’s own shares are listed on NSE. Market participants described the cross-listing structure as a practical outcome of exchange competition and market structure. Some investors also viewed it as an attempt to broaden the potential investor base. Others focused on the optics of India’s largest exchange listing on the rival venue. The filing itself does not change trading operations immediately, but it sets the stage for a public float. The listing venue is also relevant for settlement and price discovery once the stock starts trading. For now, the key fact is that NSE chose BSE for the listing.

Issue size estimates and why numbers vary online

The most shared number on social media was the estimated IPO size. Based on an unlisted market valuation of around Rs 5 lakh crore, several posts estimated the issue at roughly Rs 30,000 crore. Other reports cited a broader band, including Rs 25,000-30,000 crore, and some posts mentioned Rs 30,000-32,000 crore. The variation largely reflects that final pricing is not set at the DRHP stage. Some commentary also referenced grey market cues and an “indicative” view of valuation, not an official price band. Investors compared it with recent mega issues to frame scale. Posts cited Hyundai Motor India’s 2024 IPO and LIC’s earlier offering for context. The consistent point across sources is that it could rank among India’s largest capital market offerings. The filing is the trigger, but the final number depends on SEBI observations and final offer terms.

Selling shareholders: SBI emerges as the biggest seller

The list of selling shareholders was another heavily discussed detail. State Bank of India (SBI) is described as the largest selling shareholder in the DRHP. Reports cited SBI offering up to 24.75 million shares. Other selling shareholders mentioned in reports include MS Strategic (Mauritius) Ltd and Canada Pension Plan Investment Board. Names also included Aranda Investments (Mauritius) Pte Ltd and Bank of Baroda. State-linked institutions and insurers were also cited, such as GIC Re and The New India Assurance Company. National Insurance and United India Insurance were also referenced in the seller list. Social chatter interpreted this as a partial monetisation by long-standing institutional holders. The DRHP structure indicates the float comes from these exits, not from dilution.

How the book-building allocation is expected to work

The offer is to be made through the book-building process, as noted in the shared context. Allocation rules referenced in posts were specific and widely repeated. Not more than 50 percent of the net offer is to be allocated to qualified institutional buyers (QIBs). Not less than 15 percent is reserved for non-institutional bidders (NIIs). Not less than 35 percent is reserved for retail bidders. These are standard category splits that investors look for while planning applications. Online discussion also focused on whether retail would get meaningful room given the issue size. The draft stage does not provide a price band, so application amounts are unknown today. Still, the reservation percentages set expectations on demand distribution. Investors will watch how the final prospectus confirms these allocations.

Timeline so far: board approvals and SEBI NOC

Several posts mapped the sequence of approvals leading into the filing. NSE’s board cleared the DRHP on Monday, according to the shared updates. The IPO committee of the exchange also met to conclude the DRHP filing process. The board had earlier approved the proposed IPO on February 6. This approval followed NSE receiving a No Objection Certificate (NOC) from SEBI in January 2026, as cited in the context. Together, these steps are being treated as a formal unblocking of the listing path. The DRHP filing is not the end of the process, but it is the first public regulatory milestone. The remaining steps now depend on SEBI’s review of the draft. Social media commentary framed this as a shift from speculation to a structured timeline. The filing also revives investor interest in NSE’s unlisted market narrative.

Regulatory overhang: why the co-location issue is still cited

The co-location controversy continues to feature in public discussion around the listing. Multiple posts said NSE’s listing plans were stalled for nearly a decade due to regulatory concerns. The co-location matter was repeatedly cited as the central issue behind the long delay. Some commentary also noted that NSE is yet to close out settlement proceedings with SEBI on the co-location matter, as referenced in one report. This context explains why the DRHP filing is being treated as a turning point. At the same time, investors are reading the filing as a sign of regulatory progress rather than a clean slate. The draft submission does not automatically resolve historical issues, but it signals forward movement. Market participants are likely to track SEBI’s observations closely for any references to risk factors. Online, this has translated into a split narrative of relief and caution. The next phase will test how quickly the review proceeds.

What happens next after the DRHP submission

After a DRHP submission, SEBI reviews the draft before issuing final observations. A widely circulated estimate said the review process typically takes between 30 and 90 days. Once SEBI’s observations are received, the company proceeds to file the final prospectus with the Registrar of Companies. Only then are the price band and bidding dates typically finalised and announced. Some market chatter also speculated about possible listing windows later in the year, but those timelines were framed as expectations rather than confirmed schedules. For investors, the immediate next step is to watch for SEBI’s comments and any changes between draft and final documents. The final issue size will also become clearer at that stage. Until then, comparisons to prior mega IPOs remain directional. The filing is the start of the public process, not the finish line.
