NSE Uses AI Surveillance as IPO Plans Advance
The National Stock Exchange of India uses artificial intelligence to watch trading activity.
The technology looks for unusual behaviour that could suggest market manipulation or insider trading.
The exchange has been using its own algorithms for about two or three years.
It does not say publicly how many cases the systems have found or stopped.
NSE is also preparing to sell shares to the public through an IPO in September 2026.
The exchange says this IPO is meant to help investors discover its value, not to take advantage of a particular market moment.
More Indians are investing, with the registered investor base rising sharply since 2020.
NSE says it will need stronger technology and cybersecurity systems to support this growth.
It also says foreign investors may return to India when global investment conditions change.
The National Stock Exchange of India has used homegrown AI algorithms for two or three years to detect behavioural patterns, manipulation and insider trading.
NSE Chief Business Development Officer Sriram Krishnan said the exchange does not publish statistics on detected or prevented malpractices.
NSE's IPO is scheduled for September 17-21, 2026, with a price band of Rs. 1,700 to Rs. 1,785 per share.
NSE officials said its registered investor base grew from about 3.1 crore in March 2020 to more than 13 crore by April 2026.
The exchange said it must expand technology infrastructure, cybersecurity measures and online trading capacity as India's investor base grows.

NSE's Position
Market Considerations
Timing of the IPO
NSE's Position
NSE says the IPO is not intended to time the market and is designed to facilitate price discovery for long-term investors.
Market Considerations
The IPO is taking place amid high oil prices, a falling Indian rupee and geopolitical tensions, conditions that may affect investor decisions.
Foreign investor activity
NSE's Position
NSE says foreign portfolio investors can invest wherever they find better opportunities and may return to India after a global market correction or an AI-sector downturn.
Market Considerations
Foreign investors may choose overseas markets when they perceive India as lacking AI-focused investment opportunities or carrying greater risks.
Investor growth
NSE's Position
NSE officials say the expansion of India's investor base is sustainable because only 13.3 crore of the country's 140 crore people currently trade in capital markets.
Market Considerations
Supporting much larger participation will require major investment in online trading infrastructure and systems to address cybercrime and related threats.
