A Historic Nifty 50 Switch Is Coming: BSE Takes Wipro's Spot

MUMBAI — Stock exchange operator BSE Limited will enter India’s benchmark Nifty 50 index on September 30, 2026, replacing IT services company Wipro Limited. The change was officially announced on August 10, 2026, by NSE Indices Limited—a subsidiary of the National Stock Exchange of India (NSE)—following the regular semi-annual review of broad-market indices by its Index Maintenance Sub-Committee (Equity). The adjustment will take effect after the close of trading on September 29, 2026.

Free-Float Valuation Metrics and Index Criteria

According to official releases from NSE Indices, the inclusion of BSE Ltd follows a surge in its average free-float market capitalisation. Under Nifty 50 index methodology, an eligible non-constituent stock can replace an existing member if its six-month average free-float market capitalisation is at least 1.5 times that of the smallest index constituent.

During the six-month review period ending July 2026, BSE recorded an average free-float market capitalisation of 1.41 trillion rupees (₹1,40,879 crore). In contrast, Wipro logged an average free-float market capitalisation of 559.30 billion rupees (₹55,930 crore), making it the smallest constituent within the eligible Nifty 50 universe.

NSE Indices noted that TVS Motor Company and Divi's Laboratories were the next highest-ranked eligible entities. However, they were not considered for inclusion because the remaining lowest-ranked Nifty 50 constituents did not meet the required 1.5-times free-float market capitalisation multiplier threshold.

Market Dynamics and Sectoral Shift

The index swap highlights shifting capital allocation trends across Indian financial markets. The inclusion of Asia’s oldest stock exchange operator reflects increased retail market participation, expanding demat account additions, and higher trading volumes across derivatives and cash market segments.

Conversely, Wipro's exclusion marks a shift for one of India's oldest listed IT exporters. The IT sector has faced headwinds stemming from reduced discretionary technology spending among European and North American clients, slower deal conversions, and global macroeconomic uncertainties. The replacement will also automatically apply to the Nifty 50 Equal Weight Index.

Following its exit from the Nifty 50, Wipro will transition into the Nifty Next 50 index alongside new entrants such as Hitachi Energy India, Polycab India, Vedanta Aluminium Metal, and Vodafone Idea. Concurrently, Indian Hotels, Lodha Developers, REC, Shree Cement, and United Spirits will step down from the Nifty Next 50.

Quote Section

"BSE Ltd. has been included in the Nifty 50 index as the 6-month average free-float market capitalization of the company within the eligible universe was at least 1.5 times the 6-month average free-float market capitalization of the smallest constituent, i.e., Wipro Ltd," stated official press releases published by NSE Indices Limited on August 10, 2026.

Why It Matters

The inclusion of BSE in the Nifty 50 will trigger mandatory portfolio rebalancing by passive index funds, exchange-traded funds (ETFs), and institutional funds tracking the benchmark. Passive funds tracking the Nifty 50 will be required to reallocate capital by purchasing BSE shares and divesting Wipro holdings prior to the September 30 effective date.
