NSE IPO: Exchange Flags Major Risks in Landmark ₹30,000 Crore Filing

The National Stock Exchange (NSE) has officially filed its Draft Red Herring Prospectus (DRHP) for a massive ₹30,000 crore IPO, marking a historic moment for the Indian capital markets. While the issue is poised to be the largest in the country's history, the exchange has transparently disclosed several critical risk factors ranging from regulatory scrutiny to the complexities of Artificial Intelligence.

Heavy Reliance on Derivatives Trading

A significant portion of NSE's financial health is tied to a narrow segment of market activity. In FY26, transaction charges accounted for 78.65% of the exchange's operating revenue. Even more striking is the concentration within that figure: options trading alone contributed 60.22% of the total revenue from operations.

NSE warned that this reliance creates a vulnerability to regulatory shifts. Recent SEBI measures aimed at strengthening the equity derivatives framework have already caused a moderation in trading activity across both cash and derivatives segments. Any further tightening of regulations, increased transaction taxes, or a shift in investor preference toward alternative asset classes could significantly impact profitability.

The exchange's journey toward an IPO has been long, hampered by regulatory challenges for nearly a decade. In its filing, NSE disclosed receiving various show-cause notices, warning letters, and advisory communications from SEBI regarding governance, technology, and compliance.

Financial implications from these regulatory issues are already visible. NSE noted substantial settlement costs, including a payment of over ₹643 crore in October 2024 related to its Trading Access Point (TAP) architecture. Additionally, the exchange paid ₹40.35 crore in July 2025 following a regulatory inspection. Legal proceedings regarding the long-standing co-location and dark fibre matters also remain unresolved.

Technological Vulnerabilities and AI Risks

As a fully electronic platform, NSE identifies technology and cybersecurity as primary operational risks. The exchange cited past incidents, such as the February 2021 technical failure that caused a five-hour trading halt across all segments, and a massive DDoS attack in May 2025 that saw 395 million hits in just 11 minutes.

さらに、人工知能（AI）の台頭は新たなリスクの領域をもたらしています。NSEは、AIが監視を支援する一方で、偏った、あるいは不正確な出力を生成する可能性があることを強調しました。また、AI主導のアルゴリズム取引が市場のボラティリティを増幅させ、規制当局が検知困難な巧妙な形態の市場操縦を可能にするのではないかという懸念も高まっています。

集中リスクとIPOの構造

当取引所は、顧客に関する「集中リスク」にも直面しています。2026年度（FY26）の営業収益の46.78%を上位10社の取引会員が占めています。これら主要プレーヤーの間で業務上の混乱が生じた場合、取引所の収益に深刻な打撃を与える可能性があります。

今度のIPOは、1,489万株（14.89 crore shares）の売出し（OFS）として完全に構成されており、既存株主が保有株の約6%を売却することを可能にします。これが成功すれば、今回の発行はインドのプライマリーマーケットにおける新たなベンチマークとなるでしょう。

主なポイント

  • 収益の集中: NSEはデリバティブに大きく依存しており、オプション取引が総営業収益の60%以上を占めています。
  • 規制および法的コスト: 当取引所は、2024年末の643億ルピー（₹643 crore）の支払いを含む、規制当局との和解による多額の資金流出に直面しています。
  • 台頭するAIの脅威: 従来のサイバー攻撃に加え、NSEはAI主導の市場操縦やアルゴリズムによるボラティリティの増大を、将来の重大なリスクとして特定しています。
