NSE IPO Draft Papers Filed: ₹30,000 Cr OFS in 2026

Filing signals a long-awaited listing attempt

India’s largest stock exchange, the National Stock Exchange (NSE), has filed draft papers with the Securities and Exchange Board of India (SEBI) for an initial public offering. The filing positions NSE’s issue as one of the biggest listings expected in the country this year, alongside a potential Reliance Jio offering that has been widely anticipated. The DRHP submission is the latest step in a process NSE has been pursuing for years. The market is watching this closely because the exchange is a core piece of India’s financial infrastructure, and its IPO would be a landmark event for the primary market.

Several reports around the filing describe the offer as potentially the largest IPO in Indian stock market history. Estimates cited by industry participants put the IPO size at about ₹30,000 crore, which would surpass the previous record for the biggest IPO in India. The filing itself does not disclose final price bands or a confirmed valuation, which is typical at the draft stage.

IPO structure: a pure offer for sale

The proposed IPO is entirely an offer for sale (OFS). That means NSE will not issue any fresh shares in the transaction, and the exchange itself will not receive proceeds from the offer. Instead, the proceeds will go to the selling shareholders who are reducing their stakes.

According to the draft documents, the public issue will include up to 148,905,525 equity shares, described in multiple reports as about 148.9 million shares. This is also stated as roughly 14.89 crore shares. The sale represents about 6% of NSE’s total shares, as per the filings referenced in the coverage.

Who is selling: domestic and global investors

The set of selling shareholders includes large Indian institutions and global investors. Among those named as divesting shares through the IPO are State Bank of India (SBI), the Canada Pension Plan Investment Board (CPPIB), and Singapore’s Temasek.

Other investors listed in the reports and draft-related summaries include General Insurance Corporation of India, The New India Assurance Company, National Insurance Company, United India Insurance Company, Bank of Baroda, Stock Holding Corporation of India Limited, MS Strategic (Mauritius) Ltd, and Aranda Investments (Mauritius) Pte Ltd. One report also noted that there are ten investors divesting shares, while another described nearly 15 crore shares being sold by 23 shareholders, reflecting the broader set of selling holders cited across sources.

What the DRHP does and does not reveal yet

At this stage, the draft papers do not provide specifics on pricing or a final valuation. However, the broader reporting around the issue includes estimates and market references that investors are using to frame expectations.

One report said that the NSE IPO is pegged at roughly ₹29,780 crore in the grey market and that, at that size, the valuation is seen at over ₹5 trillion. The same report cited indicative grey market prices of at least ₹2,000. These are not official issue parameters, but they reflect how market participants are discussing the deal’s scale.

Regulatory timeline: SEBI review and listing window

Coverage of the filing indicates that regulatory review is a key near-term milestone. Market analysts quoted in the reports said such approvals typically take two to three months. Another account described SEBI’s draft prospectus review process as generally taking between 30 and 90 days.

Separately, one report said that after Indian regulatory clearances, the public offer could take at least 3 to 4 months, even though NSE has not provided a detailed timeline. The exchange is also described as having received a no-objection certificate (NOC) from SEBI earlier this year, which cleared the way for the DRHP filing.

Background: NSE’s earlier listing attempt and regulatory overhang

NSE has been trying to list since 2016, when it first submitted IPO papers. That attempt was stalled due to an ongoing regulatory inquiry, and later reporting references the co-location controversy as part of the regulatory issues that kept the listing plan on hold for nearly a decade.

The current filing is therefore being seen as the culmination of a multi-year effort to reach the public markets. NSE is described as India’s largest stock exchange and the world’s most active derivatives exchange, with leadership in the cash equities and equity derivatives segments for over a decade.

How big could it be: record comparisons and shareholder base

Multiple reports frame the IPO as a record-breaking listing if it comes in around the estimated ₹30,000 crore. That would surpass Hyundai Motor India’s IPO, which is cited at ₹27,859 crore (and also referenced as ₹27,870 crore in another report) and closed in mid-October 2024. The reporting also compares the scale against LIC’s ₹20,557-crore offer.

One report said NSE has around 1.8 lakh shareholders. A wide shareholder base and a large OFS size can both influence deal logistics, including allocation design, offer scheduling, and investor education.

Primary market context: volatility, geopolitics, and a pickup in filings

The filing arrives during a period when IPO activity has been uneven. The primary market has been relatively quiet amid weaker investor risk appetite following the recent Middle East conflict. Several large offerings were postponed, although reports noted that as tensions eased and there were indications the Iran war may be nearing an end, IPO activity began to pick up.

Data cited from an Equirus Capital report said that India’s primary market saw a slowdown, with 23 companies raising more than ₹27,000 crore via IPOs so far in 2026 amid heightened volatility and macroeconomic uncertainty. At the same time, the pipeline is building again, with insurtech firm Turtlemint Fintech Solutions slated to launch its IPO on June 19 and jewellery maker Advit Jewels set to open its issue on June 23.

Market impact: what a pure OFS means for investors

For investors, the structure matters as much as the headline size. Because NSE’s IPO is a pure OFS, the transaction does not raise new capital for the exchange. It is primarily a liquidity event and a route for existing investors to pare exposure. That can shape how investors interpret the offer, particularly in terms of use of proceeds and post-listing capital plans.

The size and prominence of the issue could also influence market attention and liquidity across the broader IPO calendar. Reports describe NSE’s offering as one of two mega IPOs expected this year, alongside Reliance Jio, and also cite other high-profile expected offerings such as Jio Platforms, SBI Funds Management (also referenced as SBI Mutual Fund), and Zepto.

Key facts at a glance

Analysis: why this filing matters for the IPO pipeline

NSE’s filing is a meaningful signal for the primary market because it tests whether risk appetite can absorb very large, institution-heavy offers after a period of volatility. It also sets a benchmark for other large issuers that are reportedly preparing to file.

The listing attempt is also notable because it follows years of delays linked to regulatory processes. The DRHP filing, coupled with the earlier SEBI no-objection certificate referenced in the reports, indicates that the process has moved from an uncertain phase into a formal review window.

Conclusion: next steps hinge on SEBI observations

NSE’s DRHP filing sets the stage for what is widely expected to be a record-scale IPO in India, structured entirely as an OFS of about 14.89 crore shares, or around 6% of the exchange. The next visible milestone is SEBI’s review and final observations, a process described as typically taking 30 to 90 days, with broader estimates suggesting the overall listing process may take 3 to 4 months after regulatory clearances. The timeline for launch and the final price will be clearer once the regulatory review progresses and the offer details are updated.
