As the National Stock Exchange (NSE) moves closer to one of the country’s most awaited public offerings, its Draft Red Herring Prospectus (DRHP) reveals that the country’s largest stock exchange is also one of its most sophisticated technology platforms.
Behind every buy and sell order executed on Dalal Street lies a massive digital infrastructure built to process billions of transactions with near instantaneous speed. According to the DRHP, NSE operates 7 data centres equipped with more than 14,000 servers, nearly 60 petabytes of storage capacity and over 2,500 racks, making it one of the largest technology infrastructures in India’s financial ecosystem.
The scale of operations is staggering. NSE’s platform connects more than 2 lakh trading terminals across over 1,400 cities and towns. On an average day, the exchange processes between 12 billion and 14 billion messages. During periods of heightened market activity, these numbers surge significantly. On March 24, 2026, NSE recorded its highest-ever single-day traffic of 21.89 billion order messages while executing 201 million trades.
The exchange’s technology systems are designed for speed and reliability. NSE’s infrastructure can process around five million messages per second while delivering microsecond response times across equity, derivatives and currency segments. The exchange has further upgraded its architecture to provide order acknowledgements within nanoseconds, a critical requirement in today’s algorithm-driven trading environment.
Technology spending has emerged as a key priority for the exchange. NSE spent Rs 1,314.6 crore on technology related operating expenses in FY26, compared with Rs 786.2 crore in FY24. Its IT capital expenditure stood at Rs 422 crore in FY26, accounting for nearly 72 per cent of total capital spending.
Resilience is another cornerstone of NSE’s infrastructure strategy. The exchange operates a primary data centre supported by a fully mirrored disaster recovery facility and a near data centre that replicates data in real time. To ensure operational readiness, NSE conducts live trading operations from its disaster recovery site twice every year.
The DRHP also underscores NSE’s focus on cybersecurity. As a designated Critical Information Infrastructure entity, the exchange reported zero data breach incidents during FY24, FY25 and FY26.
For investors evaluating the IPO, the DRHP offers a reminder that NSE is no longer just a marketplace for securities. It has evolved into a technology powerhouse where data centres, servers and digital resilience are as important as trading volumes and market share.
