NSE IPO 2026: DRHP due June 19 at Rs 500,000 crore valuation

NSE moves closer to a long-awaited listing

India’s largest stock exchange, the National Stock Exchange (NSE), is expected to take a key step toward a public listing with the filing of its Draft Red Herring Prospectus (DRHP) with SEBI. Media reports citing sources familiar with the matter indicate the draft papers could be filed this week, with one reported target date being Thursday, June 19, 2026. Other reports also suggested a June 15 or June 16 filing window, indicating the process is at an advanced stage.

The potential IPO is being tracked closely because of its scale and because NSE has been preparing for a listing for years. The draft filing is a procedural milestone, but it signals that the exchange is ready to move from preparation to execution. Sources also indicated that the issue could come to the market in the October to November period, between Navratri and Diwali.

What the DRHP filing signals

The DRHP is the core disclosure document required for an IPO in India. For NSE, filing the draft papers would formally begin SEBI’s review process for the public issue. Reports said SEBI has already granted in-principle approval, clearing what was described as a significant hurdle for the exchange.

Separately, reports also referenced a no-objection certificate granted by SEBI in January, followed by approval from the NSE board on February 6. Together, these developments indicate regulatory and internal clearances have been progressing, allowing NSE to move toward the draft filing.

IPO structure: pure OFS, no fresh issue

Multiple reports said the IPO is expected to be structured as a pure offer-for-sale (OFS), with no fresh issue of shares. That means the proceeds would go to selling shareholders, not to NSE as new capital.

Sources indicated that the offer size could be around 4% to 5% of NSE’s equity capital. This is higher than SEBI’s minimum public float requirement of 2.5% for companies valued above Rs 10,000 crore, as cited in the reports.

Valuation expectations: Rs 500,000 to 525,000 crore range

Reports indicate NSE may seek a valuation of about Rs 500,000 crore to Rs 525,000 crore. The exchange is already valued at over Rs 500,000 crore in the unlisted market, according to market participants cited in media coverage.

One report also cited an implied valuation of about Rs 500,000 crore based on unlisted share prices in the Rs 1,950 to Rs 2,050 range. Another cited unlisted shares trading near Rs 2,080, while a separate update said shares were trading above Rs 2,000 as of June 16.

A comparison in the coverage also noted that at an expected valuation of about Rs 514,000 crore, NSE would be more than three times the size of BSE, which was cited at a market capitalisation of about Rs 165,000 crore.

Issue size estimates: Rs 20,000 to 25,000 crore

On deal size, reports pointed to an expected issue size of about Rs 21,000 crore to Rs 25,000 crore. Another estimate said a 4% to 5% stake sale through an OFS could raise about Rs 20,000 crore.

While the exact size will depend on the final offer structure and price discovery, the numbers being discussed place the offering among the biggest in India’s capital markets, as described in the reports.

Shareholding: large base, key institutional holders

NSE is reported to have around 1.8 lakh shareholders. Among institutional holders, the Life Insurance Corporation of India (LIC) was specifically mentioned with a 10.72% stake. State Bank of India was also referenced as one of the primary institutional shareholders in the reports.

Because the issue is expected to be a pure OFS, the participation and intentions of existing shareholders will be central to the final structure. The DRHP is expected to clarify which shareholders are selling and the size of their respective stakes on offer.

Potential timing: October to November window

Sources indicated that the IPO could reach the market between Navratri and Diwali, putting the probable launch window in October to November. This timing would still depend on SEBI’s review, any queries raised during the process, and the time taken to incorporate clarifications into the final offer documents.

For investors, the timeline matters because it sets expectations for when a high-profile listing could open for subscription, subject to the standard regulatory sequence after the DRHP filing.

Market impact and why this matters

The market significance comes from the size of the offering, the expected valuation, and the fact that NSE is central to India’s trading and market infrastructure. A listing of a Rs 500,000 crore to Rs 525,000 crore entity would be a major capital market event and would likely attract broad investor attention.

The reported structure as a pure OFS also matters. Since there is no fresh issue, the IPO is primarily a liquidity event for existing shareholders rather than a capital-raising exercise for the exchange. That distinction affects how investors interpret the use of proceeds and the post-issue shareholding pattern.

What to watch next

The immediate next step is confirmation of the DRHP filing with SEBI and the details in the draft document. Investors will also watch for clarity on selling shareholders, the final size of the offer, and the updated timeline for the public issue.

For now, the consistent message across reports is that NSE’s IPO preparations have moved into the final stretch, with the draft filing expected shortly and a potential launch later in the year, subject to regulatory review.
