India’s planned initial public offering of the National Stock Exchange (NSE) raises concerns that it could reduce activity in the country’s unlisted share market, often described as a “shadow” market. Several reports say NSE accounts for about half of trading in this segment, meaning any change to the exchange’s market structure or pricing could spill into off-exchange trading.

The IPO is widely seen as long-delayed, and outlets link that delay to the growth of unlisted trading volumes. With a public debut, market participants expect liquidity and trading preferences to shift, potentially drawing some activity away from unlisted deals. The Business Line piece frames the risk as “hollowing out” parts of the unlisted ecosystem, while India Today emphasizes that a large share of trades could be “at risk.”

Across the coverage, the main point is the potential impact on unlisted trading rather than a specific regulatory action. Both sources focus on the size of NSE’s role in unlisted-market activity and the possibility that IPO-related changes could alter where and how shares trade.
