NSE Indices announced that BSE Ltd will replace Wipro Ltd in the benchmark Nifty 50 index effective September 30, 2026. Driven by BSE's strong free-float market capitalization growth, the semi-annual reshuffle triggers substantial passive fund reallocations, moving Wipro to the Nifty Next 50 alongside four other additions
MUMBAI — NSE Indices Ltd, the index services subsidiary of the National Stock Exchange (NSE), announced on August 10, 2026, that BSE to replace Wipro in Nifty 50 as part of its semi-annual broad-market index reconstitution. The periodic adjustment will officially take effect on September 30, 2026, following the close of trading on September 29. The index reshuffle, decided by the Index Maintenance Sub-Committee (Equity), reflects the substantial surge in trading volumes and market capitalization for Asia's oldest stock exchange operator, while pushing IT services leader Wipro Ltd out of the 50-stock benchmark index for the first time in over a decade.
Technical Qualification and Free-Float Market Cap Criteria
The decision for BSE to replace Wipro in Nifty 50 followed strict quantitative eligibility criteria established under the Nifty index methodology. According to official data released by NSE Indices Ltd, BSE Ltd registered a six-month average free-float market capitalization of ₹1,40,879 crore during the review period. In contrast, Wipro Ltd recorded an average free-float market capitalization of ₹55,930 crore, making it the smallest constituent within the benchmark index universe.
Under NSE governance rules, a non-member stock becomes eligible for inclusion in the Nifty 50 if its six-month average free-float market capitalization is at least 1.5 times that of the smallest existing constituent. Because BSE’s free-float market capitalization exceeded Wipro’s by more than 2.5 times, the Index Maintenance Sub-Committee approved the direct replacement. NSE Indices noted that secondary contenders, including TVS Motor Company Ltd (₹84,566 crore) and Divi's Laboratories Ltd (₹82,930 crore), met basic criteria but did not meet the required market capitalization threshold relative to remaining index constituents.
Broader Index Churn Across Nifty 100 and Nifty Next 50
The semi-annual review extends beyond the headline benchmark, triggering significant realignments across parent indices. Following its exit from the premier 50-stock index, Wipro Ltd will be integrated into the Nifty Next 50 index. Simultaneously, BSE Ltd will join the Nifty 100 index.
As part of the Nifty 100 and Nifty Next 50 reconstitution, five constituents will be replaced. Indian Hotels Co Ltd, Lodha Developers Ltd (Macrotech Developers), REC Ltd, Shree Cement Ltd, and United Spirits Ltd will exit the Nifty 100 and Nifty Next 50 indices. Joining BSE Ltd and Wipro Ltd as new entrants in the Nifty Next 50 are:
NSE Indices confirmed that all changes apply equally to the respective equal-weight index variants, ensuring comprehensive alignment across passive portfolio structures.
Market Impact on Capital Flows, Investors, and Asset Managers
The requirement for BSE to replace Wipro in Nifty 50 carries immediate financial implications for domestic mutual funds, exchange-traded funds (ETFs), and international institutional investors tracking NSE benchmarks.
Passive Capital Realignment: Financial analysts from quantitative research firms project that index-tracking funds will reallocate hundreds of millions of dollars ahead of the September 29 execution date. Passive inflows into BSE shares are estimated between $630 million and $740 million, driven by mandatory ETF buying.
Outflow Pressure on Wipro: Conversely, index-tracking funds exiting Wipro to mirror the updated Nifty 50 composition are expected to generate passive outflows estimated between $200 million and $250 million. However, absorption by incoming Nifty Next 50 passive funds will partially offset selling pressure.
Derivative Segment Eligibility: In accordance with index maintenance rules, only securities listed and traded in the Futures & Options (F&O) segment on the NSE are eligible for Nifty 50 inclusion. BSE's active derivative status satisfied all liquidity and trading availability benchmarks.
