Everything You Need to Know About the NSE IPO Before You Apply

Everyone has an opinion on the NSE IPO. Your broker says subscribe. Your WhatsApp group says it’s overpriced. The grey market says 12% listing gains. Your uncle says it’s the safest bet in years.

None of them have read the numbers.

This is not a hype piece. The NSE IPO is genuinely one of the most interesting listings India has seen in a long time. But interesting and worth investing in are two different things. Here’s the full picture so you can decide for yourself.

What Is This IPO, Actually?

The National Stock Exchange of India is going public. The same exchange where you’ve been buying and selling stocks for years is now offering you a chance to own a piece of it.

The IPO opens on September 17 and closes on September 21, 2026. Shares are expected to list on BSE on September 24, 2026.

The quick facts:

• Price band: Rs 1,700 to Rs 1,785 per share
• Lot size: 8 shares
• Minimum investment: Rs 14,280 (at upper band)
• Issue size: Approximately Rs 21,500 to Rs 22,500 crore
• IPO type: 100% Offer for Sale (OFS)
• Listing exchange: BSE

That last point deserves its own section.

The OFS Problem (Read This Before Anything Else)

This is a 100% Offer for Sale. Every single rupee you invest goes to the existing shareholders who are selling their stake. Not one rupee goes to NSE as a company.

That is not automatically a red flag. Many great companies have done OFS IPOs. But it does mean:

• NSE isn’t raising money to grow, build, or expand
• The people who built it are cashing out
• You’re buying someone else’s exit, not funding someone’s vision

When you see a 100% OFS, the first question to ask is: why are insiders choosing to sell now? Sometimes the answer is that the business is mature and they simply want liquidity. Sometimes the answer is that the valuation is about as good as it’s going to get for a while.

With NSE, both are probably true.

The Business: Genuinely Exceptional

Set the OFS concern aside for a moment. The underlying business is remarkable.

NSE controls 92.99% of India’s cash equity market. In derivatives, the dominance is even more extreme. The registered investor base grew from 30.87 million in March 2020 to 129 million in March 2026. That’s 4x growth in six years.

The financials tell the same story:

• Net profit margin (FY26): 55%
• EBITDA margin (FY26): 75.48%
• Debt: Zero

A 75% operating margin. No debt. A near-monopoly on India’s trading infrastructure. For long-term investors, this is the kind of business that compounds quietly for decades. The question is never whether NSE is a good business. It clearly is. The question is what price you’re paying for it.

The Numbers That Worry Me

Here’s what the hype pieces aren’t telling you.

FY26 revenue fell. NSE’s revenue from operations came in at Rs 16,601 crore in FY26, down 3.1% from Rs 17,140 crore in FY25.

FY26 profit fell harder. Profit after tax dropped to Rs 10,302 crore, down 15.5% from Rs 12,188 crore the previous year.

This is not a company growing into its valuation. This is a company being listed in the year its earnings declined. The reason is SEBI’s F&O (Futures and Options) curbs, which squeezed derivatives volumes significantly. NSE’s entire business model runs on transaction fees. Fewer derivatives trades means less revenue, less profit.

The risk is not that NSE is a bad business. The risk is that its single biggest revenue driver, the derivatives segment, is now directly in SEBI’s crosshairs. SEBI changed the rules once. They can change them again.

Valuation: Cheaper Than BSE, Expensive vs the World

At the upper price band of Rs 1,785, NSE is priced at:

• 42.89x FY26 earnings (P/E)
• 13.76x FY26 book value
• 26.61x FY26 revenue

For context, BSE currently trades at 54.28x earnings. So NSE is cheaper than BSE on a PE basis, despite being roughly 3.4x BSE’s revenue and 4x its profit. On a relative basis, NSE looks like the better value of the two.

But compare it to global exchanges and the picture changes. NASDAQ trades at a fraction of its listed market cap. Euronext even lower. NSE is being valued at roughly 1.2–1.3% of the market cap of stocks listed on it. Global peers average well below 0.2%.

The counter-argument is that India is a growth market and NSE deserves a premium. That argument isn’t wrong. But “deserves a premium” and “this specific premium at this specific moment, with falling profits” are different things.

The Regulatory Risk Is Real and Specific

NSE isn’t just exposed to generic market risk. It has a specific, documented history with regulators.

The co-location scandal, where certain brokers allegedly got preferential access to trading servers for years, resulted in penalties and prolonged scrutiny. The IPO itself was delayed for years partly due to regulatory concerns stemming from that episode.

SEBI approved the IPO. But the co-location case isn’t fully closed in public memory. And the F&O curbs that already hurt FY26 profits show that SEBI is comfortable intervening in NSE’s core revenue model when it deems necessary.

Regulatory risk with NSE isn’t theoretical. It’s already showing up in the income statement.

Grey Market Premium: What It Means and What It Doesn’t

The GMP (Grey Market Premium) is currently sitting around Rs 218 to Rs 222 per share, suggesting a potential listing premium of roughly 12% over the upper price band.

A few things to understand about GMP:

• It’s an unofficial market. There’s no regulation, no enforcement, no guarantee.
• GMP reflects short-term listing sentiment, not long-term value.
• It can change dramatically in the days between now and listing, especially if market conditions shift.
• Listing gains and long-term returns are completely different conversations.

If the GMP holds, someone applying at the upper band of Rs 1,785 might see the stock list around Rs 2,000. That’s a decent short-term return on a retail lot. But past big IPOs have seen GMP evaporate by listing day when broader markets got volatile.

Don’t apply to NSE IPO because of GMP. Apply or don’t apply based on your actual view of the business.

How to Apply (If You Decide To)

Via UPI (easiest for retail investors):

1. Open your broker app (Zerodha, Groww, Upstox, Angel, etc.)
2. Go to IPO section and find NSE IPO
3. Enter lot size and bid price (bid at Rs 1,785 to maximise allotment chances)
4. Enter your UPI ID
5. Approve the mandate on your UPI app within the deadline

Via ASBA (through your bank):

1. Log in to your bank’s net banking
2. Go to the IPO/ASBA section
3. Enter your demat account details, lot size, and price
4. Submit; the amount is blocked, not debited, until allotment

Important: Apply only once across all platforms. Multiple applications using the same PAN are rejected. If oversubscribed (almost certain), retail allotment is by lottery — one lot per lucky applicant.

So Should You Apply?

Apply if:

• You want long-term exposure to India’s capital markets growth story
• You’re comfortable holding through potential post-listing volatility
• You see this as a 5–10 year hold, not a quick flip
• You understand that a near-monopoly exchange in a country growing its investor base 4x per decade is a structurally sound bet

Think twice if:

• You’re hoping for guaranteed listing gains. The GMP suggests upside but nothing is guaranteed with a Rs 22,000 crore issue.
• You’re worried about valuation. At 43x declining earnings, this is not a cheap stock.
• You’re uncomfortable with regulatory risk. SEBI has intervened in NSE’s revenue model before and can do so again.
• You’re expecting the same 54x re-rating as BSE. Whether that premium expands from here is genuinely uncertain.

NSE is a great business at a fair-to-full price, being sold partly because profits just dropped 15%. The long-term bull case is India’s investor growth story. The short-term risk is that the IPO is coming at peak valuation during a year of declining earnings.

The One Thing Most People Are Missing

Everyone is debating whether NSE deserves a higher PE than BSE. That’s the wrong conversation.

The right question is this: what happens to NSE’s earnings if SEBI continues tightening F&O regulations?

Derivatives are NSE’s crown jewel. They’re also increasingly under regulatory scrutiny, with SEBI citing retail investor losses in options trading as a concern. If that scrutiny deepens and volumes fall further, FY26’s 15.5% profit decline won’t be an anomaly. It’ll be the beginning of a trend.

NSE’s monopoly position doesn’t protect it from that risk. If SEBI decides that options trading needs to be curtailed for retail investor protection, NSE can’t simply pivot to another revenue stream overnight.

That’s not a reason to never invest. It’s a reason to size your position with that risk in mind.

The business is exceptional. The timing is imperfect. The price is fair but not cheap.

Apply with clear eyes, not because everyone else is.
