Why It Happened: The Real Story Behind June 18, 2026’s Move
Today’s dip in BSE shares, despite its recent operational successes, can be largely attributed to the National Stock Exchange’s official filing of its Draft Red Herring Prospectus (DRHP) for a mega IPO. This move has shifted market attention, creating a direct valuation comparable that was previously absent.
1. NSE’s Mega IPO Filing Creates Valuation Pressure?
The National Stock Exchange (NSE) officially filed its preliminary IPO papers with SEBI on June 17, 2026, for an estimated ₹30,000 crore public issue. This is poised to be the largest IPO in Indian stock market history. This development immediately puts BSE’s valuation under scrutiny, as investors now have a clear, albeit future, alternative for investing in an exchange. The market often reacts to such significant news by re-evaluating existing players.
2. BSE’s Derivatives Market Share Gains Face Scrutiny?
BSE has made significant strides in the derivatives segment, even surpassing NSE in notional F&O turnover in April 2026, capturing 55.4% of the market. This shift was primarily driven by BSE’s lower transaction charges following the Securities Transaction Tax (STT) hikes in February 2026. However, NSE still maintains a dominant 66% share in options premium turnover, which is a key revenue driver. The market is now weighing BSE’s operational gains against NSE’s overall size and profitability.
3. Regulatory Clarity for NSE’s Decade-Long IPO Journey?
NSE’s IPO journey was stalled for nearly a decade due to regulatory hurdles, including the co-location controversy. The exchange’s settlement application in June 2025 and SEBI’s no-objection certificate in February 2026 finally cleared a major path for the IPO. This regulatory clarity, culminating in the DRHP filing, signals that the long wait for NSE’s public listing is nearing its end, making it a tangible investment prospect for the first time in years.
The Broader Picture: What This Means for Indian Markets
The impending NSE IPO is a landmark event for Indian capital markets. It introduces a direct, publicly traded competitor to BSE, which has been the sole listed exchange for some time. While BSE has shown remarkable growth, particularly in its equity derivatives segment with revenue more than doubling in FY26 to ₹3,134 crore, NSE remains significantly larger in terms of overall profitability. For instance, NSE’s consolidated profit after tax for FY26 was ₹10,302 crore, almost four times BSE’s ₹2,487 crore. This disparity in scale and profitability will inevitably influence how investors perceive the two exchanges.
The market is now in a phase of reassessment. BSE’s stock has seen a strong surge of 54.31% in the last 12 months and 58.13% year-to-date on the NSE, outperforming the Nifty 50. However, the arrival of a larger, more profitable peer like NSE on the public markets could lead to a re-evaluation of BSE’s current valuation multiples. The “battle of the bourses” is not just about market share in trading segments, but also about investor perception and valuation in the public domain.
What the Data Shows for Investors
The data clearly shows that BSE has delivered strong operational performance, with its Q4 FY26 net profit rising 61% year-on-year and revenue growing 85%. This robust growth, especially in its equity derivatives segment, highlights its ability to innovate and capture market share. The average daily notional turnover for equity derivatives on BSE skyrocketed to ₹245 trillion in Q4 FY26.
However, NSE’s financial scale is considerably larger. Its total income for FY26 stood at ₹18,713 crore, with a profit after tax of ₹10,302 crore. This pattern suggests that while BSE is a strong growth story, NSE’s established dominance and higher profitability margins (PAT margin at 62.9% versus BSE’s 52.3%) present a different investment profile. The upcoming NSE IPO, being an Offer for Sale (OFS), means existing shareholders are selling their stakes, not that the company is raising fresh capital. This means the IPO will primarily offer liquidity to existing shareholders and a new investment avenue for the public.
Frequently Asked Questions
1. Has NSE’s IPO been officially filed?
Yes, the National Stock Exchange (NSE) officially filed its Draft Red Herring Prospectus (DRHP) with SEBI on June 17, 2026, for an initial public offering estimated at around ₹30,000 crore.
2. How does BSE’s recent performance compare to NSE’s?
BSE reported a 61% jump in Q4 FY26 net profit and 85% revenue growth, marking its highest-ever performance in 150 years. It also gained significant market share in notional F&O turnover in April 2026, reaching 55.4%. In contrast, NSE reported a 15% decline in profit after tax to ₹10,302 crore in FY26 compared to FY25, though its Q4 FY26 PAT rose 19% sequentially to ₹2,871 crore.
3. What is the expected timeline for the NSE IPO?
While the DRHP has been filed, the NSE IPO is expected to take at least three to four months to list after receiving all necessary regulatory clearances, likely before December 2026.
4. What are the key differences between investing in BSE shares now versus waiting for the NSE IPO?
Investing in BSE shares now means investing in an already listed entity with a proven track record of recent strong operational growth and market share gains in specific segments. Waiting for the NSE IPO means gaining exposure to India’s largest exchange by volume and profitability, but it involves waiting for the listing process to complete and evaluating its valuation at the time of the IPO. NSE’s IPO will introduce a direct, larger comparable for BSE in the public markets.
The Bottom Line
Today’s market activity and the latest news highlight a fascinating dynamic between India’s two major exchanges. BSE’s strong operational performance and significant gains in the derivatives market are clear, tangible facts for investors to consider. However, the official filing of NSE’s mega IPO introduces a powerful new variable, creating a direct valuation benchmark that will shape market perceptions. The data shows BSE’s impressive growth, but also NSE’s sheer scale and profitability. Investors now have a clearer understanding of both the immediate opportunities and the future landscape of exchange investments in India.
