BSE to Join Nifty 50, Replacing Wipro From September 30: What Investors Need to Know
BSE Ltd is set to enter the benchmark Nifty 50 index, replacing IT major Wipro, in a significant change announced as part of NSE Indices’ latest semi-annual index review. The reshuffle will become effective from September 30, 2026, based on the closing prices of September 29.
The announcement marks a major milestone for BSE, as the stock exchange operator moves into India’s flagship 50-stock benchmark following a sharp rise in its market capitalisation and free-float market capitalisation.
BSE to Replace Wipro in Nifty 50
According to the latest index review announced by NSE Indices on August 10, BSE will replace Wipro in the Nifty 50. The change is part of the regular semi-annual review of the benchmark index.
Under the Nifty 50 methodology, an eligible stock can qualify for inclusion when its average free-float market capitalisation is sufficiently higher than that of the smallest existing constituent. In this case, BSE’s average free-float market capitalisation was at least 1.5 times that of Wipro, supporting its inclusion in the index.
The change will take effect after the market closes on September 29, 2026, with BSE becoming a Nifty 50 constituent from September 30, 2026.
BSE Shares React to Nifty 50 Inclusion
BSE shares came into focus following the announcement, with the stock witnessing a sharp move as investors assessed the potential impact of its entry into the benchmark index.
The inclusion is particularly significant because Nifty 50 constituents are widely tracked by index funds, exchange-traded funds and other passive investment products. As a result, stocks entering or leaving the index can experience additional buying or selling activity around the effective date.
BSE shares were reported to have gained more than 3% during trading amid expectations surrounding the Nifty 50 inclusion.
Why Is BSE’s Nifty 50 Entry Important?
BSE’s inclusion represents more than just an index reshuffle. It highlights the stock’s rapid rise in market value and its increasing importance within India's capital-market ecosystem.
Being included in the Nifty 50 can potentially increase a company's visibility among domestic and global investors. More importantly, passive funds tracking the index generally need to adjust their portfolios when the index composition changes.
This could create additional demand for BSE shares around the implementation date, although the actual impact will depend on the stock's index weight, fund flows and market conditions.
Wipro Set to Exit the Nifty 50
While BSE enters the benchmark index, Wipro will move out of the Nifty 50.
Wipro has been part of the index for a long period, although it had previously exited the benchmark during 2013 following a demerger-related change before returning later that year. The latest exclusion comes as BSE's free-float market capitalisation has risen substantially relative to Wipro's position.
The removal could also result in selling pressure from passive funds that track the Nifty 50, as these funds typically need to reduce or eliminate their exposure to stocks removed from the index.
Potential Passive Fund Flows
One of the key factors attracting investor attention is the potential for passive investment flows following BSE's inclusion.
Market estimates cited after the announcement suggest that BSE could receive significant buying from passive funds, while Wipro could face corresponding outflows following its removal. The exact amount of these flows can change depending on index weights, prices and fund positioning.
Therefore, investors are likely to closely watch both stocks as the September 30 implementation date approaches.
What Happens Next?
The index change will not take effect immediately.
The announced timeline is:
The September 29 closing session could therefore become an important trading event, as index-tracking funds prepare for the new Nifty 50 composition.
Bottom Line
BSE's entry into the Nifty 50 marks a major development for India's capital-market landscape. The stock exchange operator will replace Wipro in the benchmark index from September 30, following NSE Indices' semi-annual review.
For BSE investors, the inclusion could bring greater visibility and potential passive fund demand. For Wipro shareholders, the exclusion could create short-term index-related selling pressure.
However, index inclusion or exclusion alone does not determine the long-term fundamental performance of a company. Investors will still need to track earnings, valuations, business growth, market conditions and future cash flows alongside the impact of the index reshuffle.
