NSE IPO valuation: pricey P/E, options risk in focus

Social media discussion around the NSE IPO is splitting into two clear camps: those calling the price “fair” versus those calling it “fully priced” for a business with visible regulatory and growth sensitivities. The core debate is not whether NSE is a strong franchise, because most posts accept it is India’s dominant exchange. The debate is whether the IPO price offers enough downside protection for new buyers. Many comments focus on the headline P/E multiple, but also on what happens when one-off items and near-term run-rate profits are considered. Another frequent thread is NSE’s revenue concentration in derivatives, particularly weekly options, and the risk of slower growth or regulatory tightening. Some posters also compare NSE’s valuation to global exchange operators, which trade at notably lower earnings multiples. There is also a practical angle: unlisted-share buyers from recent months are sitting on losses versus the IPO band and will face a lock-in. Put together, the conversation is less about the business quality and more about entry price and risk-reward.

IPO basics investors are using for valuation

The NSE IPO opens on 17 September 2026 with a price band of ₹1,700 to ₹1,785 per share. At the upper end, the offer values NSE at up to about ₹4.42 lakh crore, or roughly $16 billion, based on the figures cited in social posts and reports. At the lower end, the valuation is discussed as about ₹4.2 lakh crore. The issue size referenced in discussions is around ₹22,569 crore, also described around ₹22,561.57 crore in another snippet. Investors are required to bid for a minimum of 8 shares, which affects retail ticket size and participation behavior. Sources cited in the conversation say the band is 15 percent to 20 percent below roadshow expectations. The same thread notes the valuation is also materially below what private market sales implied earlier, including a reference to private sales in 2024. Those “discount to expectations” facts are being used by some to argue the IPO is reasonably priced.

Headline P/E versus adjusted P/E: why the range matters

A widely shared number in the debate is FY26 EPS of about ₹41.6, which implies a P/E around 43x at ₹1,785. Posts also cite a headline P/E of 42.9x at the upper price band. However, FY26 profit included a one-off ₹1,391 crore SEBI settlement provision, and several commentators adjust for it. Stripping out that provision brings the multiple closer to about 38x, according to the same threads. Another approach used in social posts is a Q1 FY27 run-rate, which puts the multiple at about 35x. At the lower band of ₹1,700, the headline multiple is cited around 40.8x. Put together, the “honest range” repeated in discussions is about 35x to 43x, depending on whether one-offs and run-rate are considered. That range matters because sentiment shifts sharply between “fair” and “expensive” once investors move from 35x to 43x.

NSE versus BSE: a discount that still raises questions

Several posts frame the IPO as “cheaper than BSE” on a P/E basis, and the numbers shared support that in some comparisons. One cited table puts NSE at 43x versus BSE at 47.8x, while other threads compare NSE around 43x to BSE around 53x or 54x. There is also a claim that NSE is priced below BSE per rupee of profit because NSE’s FY26 profit fell 15.5% while BSE’s rose 88%. Another snippet adds that BSE’s profits were helped by options volumes NSE has lost, which complicates simple peer comparisons. Social posts also mention a “roughly 30% discount” to BSE on FY27 earnings estimates, despite NSE being nearly three times the size. But that perceived bargain is paired with a warning: the discount can reflect different growth expectations and different business mix risks, not only mispricing. Commentators point out that if the market is paying a high multiple for BSE, that does not automatically make NSE’s multiple attractive. The common conclusion is that the valuation gap is interesting, but it does not by itself create a margin of safety.

The options dependence risk that keeps coming up

The most repeated business risk in the thread is NSE’s dependence on the options segment for around 60% of its revenue. A key detail repeatedly highlighted is that a majority of this options revenue is tied to weekly options. That concentration is described as a “key concern” and something investors should monitor closely. The logic is straightforward: if weekly options activity slows, or if regulations change the economics, revenues could be more volatile than investors expect from an exchange franchise. Some posters link this directly to valuation comfort, arguing that high multiples need more diversified and predictable revenue streams. Others counter that NSE’s dominant market position supports resilience, but even they concede concentration is a factor. The context also mentions “regulatory overhangs,” which amplifies this sensitivity. Because the discussion is based on public commentary, it does not quantify the exact regulatory outcomes, but it treats the risk as real and near-term. As a result, many social posts argue the IPO price leaves limited room for an earnings miss.

Growth signals investors are comparing across exchanges

A major support point for the “valuation is not cheap” side is recent growth divergence between NSE and BSE. One set of posts says NSE’s FY26 profit fell 15.5% while BSE’s rose 88%, and that this partly explains why NSE looks cheaper per rupee of profit. Another comparison says NSE’s net profit growth in Q1 FY27 was 11% year-on-year versus 65% for BSE. These are not being presented as long-term forecasts, but they shape near-term sentiment about momentum and premium multiples. Some commentators explicitly say that looking only at FY26 earnings may not give a true picture, because the growth outlook differs across the two exchanges. Others use a longer lens, citing that NSE’s profit CAGR over the last five years is “just 8%” and that “this year could see an earnings decline,” in one investor post. In that framing, a mid-to-high 30s or low 40s P/E starts to look demanding. The bullish counterpoint in the thread is that the pricing is “neither cheap nor expensive,” suggesting a balanced view rather than a deep-value entry. Overall, the growth comparison is central to whether investors see the IPO multiple as justified.

Global peer multiples: why the premium feels uncomfortable

Another recurring argument is that NSE’s IPO valuation is expensive compared with global peers. Posts cite Nasdaq, ICE (Intercontinental Exchange) and Cboe Global Markets trading at about 26x, 23x and 21x trailing twelve-month earnings, respectively. Against those, NSE’s roughly 35x to 43x range stands out as a premium. A separate thread broadens the peer set, saying NSE’s valuation implies a forward multiple of 35x to 38x FY2028 earnings, higher than the 23x to 31x range for operators such as Nasdaq, CME Group, Deutsche Börse, HKEX and LSEG. Social commentary also argues that these global peers have a more diversified revenue mix and have delivered better growth than NSE in the last two years. The core implication is not that NSE should trade exactly at global multiples, but that a premium needs strong, visible growth and diversification. Because the same discussion flags slower derivatives growth outlook and regulatory risks, the premium becomes harder for some investors to accept. This is why several posts conclude that the IPO does not offer sufficient margin of safety at the current pricing. It is also why “wait for listing” is a common strategy shared online.

The unlisted-share angle and the six-month lock-in

The IPO is also being viewed through the lens of recent unlisted trading. Social posts say buyers of unlisted NSE shares at ₹2,025 to ₹2,040 are already about 12% “underwater” at the top of the IPO band. This matters because it changes the near-term supply and sentiment dynamics after listing. The same thread notes these unlisted holders are locked in for six months after listing, meaning they cannot immediately exit even if the listing price disappoints. Some market veterans also highlight that unlisted prices are based on relatively few trades and are not directly comparable to a widely discovered listed-market price. One comment adds that the difference between the last unlisted price and the closure price before filing of the RHP was around ₹175, suggesting that gap could translate into grey market premium expectations. Another point is that the IPO band is said to be 15% to 20% below roadshow expectations, which can be read as an attempt to improve IPO optics versus prior unlisted levels. Still, for new buyers, the unlisted backdrop acts as a warning that private-market pricing can be optimistic. This is feeding the cautious “wait for better entry points” narrative.

So is the IPO overpriced, or simply fully priced?

Across posts, the most defensible takeaway is that the IPO appears “ok” on a relative basis to BSE but expensive versus global exchanges. The valuation depends heavily on which earnings base investors use: FY26 reported, FY26 adjusted for the SEBI settlement provision, or a Q1 FY27 run-rate. Using those bases, the discussion anchors NSE’s multiple broadly between about 35x and 43x, and as high as 48x at the upper end in some commentary. The margin-of-safety question then turns to business mix and growth: around 60% of revenue tied to options, much of it weekly, is the key concentration risk highlighted. On growth, the context repeatedly contrasts NSE’s weaker recent profit trajectory with BSE’s stronger recent growth rates. Supporters of the pricing point out that the band is below earlier unlisted and roadshow expectations, and that NSE remains the dominant exchange with over 90% share in equities cash turnover value. Skeptics respond that dominance does not automatically offset a premium multiple when regulatory overhangs are part of the story. A pragmatic view repeated online is to consider waiting for post-listing price discovery rather than chasing the IPO. In short, the debate is less about “overpriced versus underpriced” and more about whether investors are being compensated for the risks at the offered multiple.

What investors are watching after listing

The social conversation suggests a small checklist that will likely dominate post-listing scrutiny. First is whether options growth, especially weekly options, stays robust enough to support earnings expectations. Second is how any regulatory actions affect volumes, product structure, or revenue economics, given the repeated mention of regulatory overhangs. Third is whether NSE’s profit trajectory stabilises after FY26, particularly because FY26 included the ₹1,391 crore settlement provision that distorts comparisons. Fourth is whether the valuation gap to BSE narrows through NSE upside, BSE downside, or some combination. Fifth is how the stock trades once pre-IPO and unlisted holders eventually become free to sell after the six-month lock-in. Finally, investors are likely to keep one eye on global peer multiples, because that is the benchmark being used to argue that NSE is at a premium. None of these points decides the investment case alone, but together they determine whether a 35x-43x earnings multiple proves sustainable. That is why the prevailing tone online is cautious and valuation-driven rather than celebratory.
