As West Bengal awaits the outcome of Assembly Elections 2026, its contribution in the Indian economy and market capitalization of the Indian stock market remains interesting. West Bengal is India's six largest state economies, hosting nearly 300 listed companies, according to data from Ace Equity. Despite the sizable number of listed companies, West Bengal contributes Rs 17.45 lakh crore out of Rs 463.3 lakh crore in India Inc's mcap, or contributing little more than 3.75 per cent to the total BSE market capitalisation, highlighting a relatively modest but well-diversified presence in India’s equity markets.

It was followed by names like Coal India Ltd (mcap of Rs 2.95 lakh crore), Britannia Industries Ltd (mcap of Rs 1.37 lakh crore) and Tata Consumer Products Ltd (mcap of Rs 1.15 lakh crore). Other top names like Linde India (Rs 62,341 crore), Berger Paints India (Rs 53,893 crore) and Hindustan Copper Ltd (Rs 53,709 crore) also command a valuation of more than 50,000 crore. Names like GRSE, UCO Bank, ITC Hotels, Bandhan Bank, CESC, Himadri Speciality Chemical, Exide Industries, Shyam Metalics, EIH and Emami are also valued between Rs 20,000-35,000 crore.

Assembly Elections in West Bengal were carried out in two phases- April 23 and April 29, with results to be declared on Monday, May 04, 2026. Voter turnout in West Bengal exceeded 90 per cent, competing welfare versus governance narratives dominated the election. Exit polls suggest the Bharatiya Janata Party (BJP) is set to win West Bengal and outseat ruling All India Trinamool Congress (TMC) with 155-160 seats in the 294-member assembly. Incumbent TMC is projected to win 125-130 seats, while up to five seats may go to others as per the prima-facie polls. A BJP win shall end 15 years of TMC rule and signalling a major political shift in a state.
