NSE IPO 2026: BSE volumes, valuation after DRHP filing

Introduction: NSE’s IPO milestone puts BSE in focus

NSE’s filing of its draft red herring prospectus (DRHP) has shifted the market conversation from “if” to “what next” for India’s exchange sector. One of the more unusual outcomes is that the listing of NSE could create direct, near-term business benefits for its main rival, BSE. The logic is mechanical rather than sentimental: NSE shares are expected to list on BSE, turning a competitive event into a potential fee and volume opportunity for BSE. At the same time, the filing also raises a tougher question for BSE shareholders. If NSE becomes a listed, priced benchmark, will BSE continue to enjoy a scarcity premium as the only listed exchange play in India? With BSE’s stock already up about 44% in 2026, analyst commentary is increasingly separating sentiment-driven moves from fundamentals.

What the DRHP filing changes and what it does not

Analysts broadly describe the DRHP filing as a confirmation event rather than a new trigger for BSE. Paresh Bhagat, Chairman of Mangal Keshav Financial, called investor re-evaluation a “fairly natural knee-jerk reaction,” but argued that structurally little changes for BSE’s core business. The IPO is described as a pure offer-for-sale, meaning no fresh capital is raised for NSE and the transaction mainly transfers stakes from existing shareholders. The filing removes the long-running uncertainty around whether NSE’s listing will happen, but does not directly alter BSE’s earnings trajectory or balance sheet. What does change is that markets can move from indirect speculation to a direct, priced comparison between NSE and BSE once the listing happens. That pricing anchor may influence how investors value BSE going forward.

Why NSE’s listing can still help BSE operationally

A central point in the debate is that NSE’s shares are expected to be traded on BSE. Regulatory rules referenced in the text indicate that NSE cannot list on its own platform and will trade only on BSE and the Metropolitan Stock Exchange of India (MSEI). This creates a straightforward revenue pathway for BSE: more trading activity in NSE shares can mean higher fee-based revenues. The listing is also seen as a potential boost to BSE’s cash-market activity, where its market share has been stuck at about 6-8% for years. While the direct effect depends on actual trading behaviour after listing, the structure makes BSE a necessary venue for secondary-market turnover in NSE shares.

The key investor issue: BSE’s rally is already pricing in NSE

Several analysts argue that much of the “NSE listing advantage” has already been reflected in BSE’s stock price. Sourav Choudhary, MD at Raghunath Capital, said most positives tied to NSE’s eventual listing are already in the price, with BSE having been re-rated over the past few years. He also linked that re-rating to BSE’s own earnings growth and derivatives market-share gains, not only the IPO narrative. In this framing, the next leg of upside depends more on earnings delivery than event-driven optimism. If BSE continues to grow its derivatives franchise and maintain operating leverage, the stock can still create value through profit growth and earnings upgrades. But Choudhary said analysts do not expect a meaningful further re-rating in BSE purely because NSE filed its DRHP.

NSE as a benchmark: valuation discipline becomes harder

Ishan Tanna, Senior Associate at Ashika Capital, took a more constructive near-term view. He said the DRHP filing ends a decade-long uncertainty and provides a direct valuation benchmark for India’s exchange industry. That benchmark could initially work in BSE’s favour by drawing attention to capital market infrastructure businesses and the structural growth opportunity from increasing financialisation in India. However, Tanna also stressed that once NSE is listed, investors are likely to compare valuations, growth prospects, and profitability metrics of both exchanges more rigorously. That makes valuation discipline more important for BSE at current price levels. Tanna’s view also implied that the investment decision should be driven more by valuation and time horizon than by the IPO timeline alone.

Scarcity premium at risk as NSE becomes investable

A major theme is that BSE has benefited from being the only listed, pure-play Indian exchange for years. That “only listed exchange” status supported a scarcity premium and helped the stock’s strong run, including the roughly 44% rise in 2026, which the text notes has outpaced the Nifty’s negative return. NSE’s listing would end that exclusivity and create a transparent peer benchmark. One analyst observation in the text notes the comparison is “unflattering” on one count: NSE generates nearly four times BSE’s profits at higher margins, yet trades at a lower valuation multiple. If the market continues to value NSE cheaper despite stronger profitability, BSE’s premium could come under pressure. Alternatively, a strong public valuation for NSE could validate the overall exchange theme and bring more investor attention to both names.

Market mechanics: index inclusion and forced buying

Another channel of potential benefit for BSE is index-related flows. The text states that NSE will be included in BSE’s major indices after listing. If that occurs, mutual funds tracking those indices would need to buy NSE shares, which can increase institutional trading activity on BSE. Higher turnover would typically support transaction-fee revenues for an exchange, aligning with the view that NSE’s debut can be a direct revenue opportunity for BSE. The text also argues that as a listed entity, NSE will be obliged to disclose developments and price-sensitive information on the platform, increasing transparency around the country’s leading exchange. That transparency may affect how investors evaluate the sector once public filings start coming regularly.

Competition context: the late-2025 expiry day reshuffle

The competitive backdrop between the two exchanges has also shifted recently. The text points to an expiry day reshuffle in late 2025 that reversed the structural advantage BSE had enjoyed. This matters because derivatives market share is repeatedly cited as a driver of BSE’s recent performance. If competition in derivatives remains intense, investors may focus less on the IPO headline and more on whether BSE can sustain its gains in F&O. That is also why multiple analysts emphasised earnings delivery and business execution as the key variables after the DRHP event.

What analysts are telling clients about BSE vs NSE

Gaurav Sharma, head of research (equity) at Globe Capital Market, said BSE has run ahead of fundamentals and saw better risk-reward in NSE, citing its stronger earnings profile and dominant share in revenue-generating turnover, along with a potential re-rating catalyst from the IPO. In contrast, Sunny Agrawal, head of fundamental retail research at SBI Securities, attributed BSE’s outperformance to sustained market share gains in derivatives and said he expects BSE’s earnings growth to continue outpacing NSE’s. Another view in the text, attributed to “Dr Singh,” described the NSE IPO as a major benchmark event for valuing exchange businesses, and suggested a strong NSE valuation could benefit BSE by highlighting the sector’s profitability and attractiveness. Separately, the text notes unlisted NSE shares have risen nearly 4% over the same period, based on data from Unlisted Arena, as investors position for an IPO-led re-rating.

Key numbers and claims mentioned so far

Conclusion: a revenue opportunity, but also a tougher benchmark

NSE’s DRHP filing reduces uncertainty around a listing that has been anticipated for years, and it brings the Indian exchange sector closer to having a clear, publicly traded benchmark. For BSE, the listing structure itself could support volumes and fee revenues because NSE shares are expected to trade on BSE and be added to key BSE indices. But the same event also ends BSE’s scarcity advantage and invites sharper scrutiny of relative valuation and profitability, especially given the text’s point that NSE generates nearly four times BSE’s profits at higher margins. The immediate debate for investors is whether BSE’s current price is justified by ongoing earnings delivery, particularly in derivatives, rather than by the IPO timeline alone. The next major checkpoint will be when NSE’s offer details and valuation become clearer, and when markets can compare both exchanges using disclosed, listed-company metrics.
