NSE IPO: Exchange Flags Derivatives Reliance and AI Risks in DRHP

As the National Stock Exchange (NSE) prepares for a massive ₹30,000 crore public issue, its draft red herring prospectus (DRHP) has provided a candid look at the significant operational and regulatory hurdles ahead. The filing reveals a heavy dependence on specific trading segments and a growing landscape of technological and artificial intelligence risks.

High Reliance on Derivatives Trading

A critical takeaway from the NSE’s filing is the exchange's concentrated revenue model. In FY26, transaction charges accounted for a staggering 78.65% of the exchange's operating revenue. Even more striking is the reliance on the derivatives segment, with options trading alone contributing 60.22% to the total revenue from operations.

The exchange noted that recent regulatory interventions by SEBI to tighten the equity derivatives framework have already moderated trading activity across both cash and derivatives segments. NSE cautioned that further regulatory tightening, increased transaction taxes, or a shift in investor preference toward alternative asset classes could significantly impact trading volumes and overall profitability.

The DRHP highlights a history of intense regulatory oversight. NSE disclosed that it has received various show-cause notices, warning letters, and advisory communications from SEBI regarding operations, governance, and technology.

Financial implications of these regulatory hurdles are already evident. The exchange reported paying over ₹643 crore in October 2024 to settle proceedings related to its Trading Access Point (TAP) architecture and network connectivity. Additionally, a settlement of ₹40.35 crore was made in July 2025 following regulatory inspection findings. Ongoing legal proceedings regarding co-location and dark fibre matters remain unresolved, posing potential reputational and financial risks.

Technology Failures and Cyber Vulnerabilities

Given its entirely electronic ecosystem, NSE identified technical stability as a primary risk. The exchange recalled the significant February 2021 technical outage, which paralyzed risk management and settlement systems, forcing a trading halt for over five hours.

Cybersecurity remains a constant battleground. The exchange disclosed a massive distributed denial-of-service (DDoS) attack in May 2025, which saw nearly 395 million hits within just 11 minutes. While operations remained largely intact, the incident caused significant slowdowns in webpage access.

The Emerging Challenge of Artificial Intelligence

NSE has identified AI and machine learning as dual-edged swords. While AI aids in surveillance and analytics, the exchange warned that flawed algorithms could lead to biased outcomes or regulatory breaches. Furthermore, the rise of AI-driven algorithmic trading could amplify market volatility and facilitate sophisticated forms of market manipulation.

The exchange also flagged "AI-powered" threats, including deepfake-enabled impersonation and data leakage through third-party AI tools. As regulations evolve, NSE anticipates stricter compliance requirements regarding the transparency and auditability of AI systems used in financial markets.

Key Takeaways

  • Revenue Concentration: NSE is heavily reliant on derivatives, with options trading contributing over 60% of its total operating revenue.
  • Regulatory & Legal Costs: The exchange has faced significant financial penalties, including a ₹643 crore settlement related to its TAP architecture.
  • Tech & AI Risks: Beyond traditional cyberattacks, the exchange faces new threats from AI-driven market manipulation and algorithmic volatility.
