Why BSE, CDSL and Other Stocks Are the Ultimate Winners of the IPO Boom

Synopsis: India’s primary market is heading into one of its more active IPO cycles in years, with Zepto’s Rs. 11,000 crore issue, Razorpay’s $600 million filing, and anticipated listings from Reliance Jio and NSE already in the pipeline and four listed market infrastructure companies are set to capture the financial flows that follow.

India’s capital markets are entering a period of unusual concentration. A cluster of marquee primary market filings is queued for the coming months, spanning consumer tech, fintech, and some of the country’s most prominent unlisted institutions. When these listings arrive, the direct beneficiaries will not be sector peers; they will be the companies that operate the infrastructure through which every listing fee, demat account opening, mutual fund SIP, and post-listing registry mandate flows. Four names in that layer sit at the centre of this cycle, each with a distinct but equally direct exposure.

1. BSE

BSE is India’s oldest stock exchange and the primary listing venue for a large portion of the high-profile names in the current IPO queue. For each company that lists on its platform, BSE earns listing fees, processes application volumes, and sees associated transaction activity across its derivatives and currency segments rise in tandem. This is direct revenue linkage, not a macro proxy. The scale of individual listings matters: a Reliance Jio or NSE debut would rank among the most significant in the exchange’s history by application volume and listing-day turnover alike.

FY26 already showed how sharply that leverage operates. Revenue rose to Rs. 5,148.1 crore and net profit doubled to Rs. 2,421.83 crore. BSE’s market capitalisation currently stands at Rs. 1,69,534 crore, with the stock delivering 54.31 percent returns over the past year. A pipeline weighted toward large-cap and consumer-facing names is precisely the listing profile that drives sustained application volumes and exchange-related fee income over an extended window, not just in the listing month.

2. CDSL

Central Depository Services Limited holds the demat account through which every retail investor participates in an IPO, from application through allotment and into post-listing settlement. When a high-visibility listing arrives, it typically triggers a wave of first-time account openings from investors entering equity markets specifically for that issue. CDSL earns processing fees on IPO applications and account maintenance charges on every demat account for the duration of its active life. Each large listing thus becomes a dual revenue event: immediate income at application and recurring income from the accounts that result.

FY26 captured that compounding effect clearly. CDSL became Asia’s first depository to cross 18.01 crore active demat accounts, adding 2.71 crore new accounts during the year alone. Standalone income reached Rs. 1,096 crore. With under 10 percent of India’s population currently holding a demat account, every large-name listing, whether a consumer-facing issue like Zepto or an institutional heavyweight like Reliance Jio, pulls in a fresh cohort whose maintenance fees recur for years after the IPO closes.

3. CAMS

Computer Age Management Services operates as a Registrar and Transfer Agent for India’s mutual fund industry, running the back-end processing infrastructure through which SIP registrations, redemptions, and AUM administration flow. Its connection to the IPO cycle runs through a well-established post-listing pattern: investors who receive allotments frequently deploy proceeds into mutual funds in the weeks that follow, and many first-time market entrants initiate SIPs shortly after their initial exposure to equity markets through an IPO.

CAMS captures a dominant share of that flow. The company holds approximately 68 percent of the mutual fund RTA market, administers assets of Rs. 55.1 lakh crore, and processes 65 percent of all new SIP registrations in the country. Each listing cycle that brings fresh investors into the financial system expands CAMS’ active account base in the months that follow. Given its AUM-linked fee structure, incremental inflows translate to bottom-line growth with limited additional operating cost. The revenue from IPO-driven financialisation accrues slowly, but it compounds.

4. KFin Technologies

KFin Technologies, trading as KFintech, operates across two distinct parts of the market infrastructure stack. On the issuer side, it manages corporate registries, handles shareholder servicing, and runs the settlement and compliance work that newly listed companies require from their first day on exchange. On the fund administration side, it acts as an RTA for mutual funds and alternative investment structures, with a growing international presence across Southeast Asia and the Middle East.

FY26 revenue came in at Rs. 1,301.5 crore, up 19.3 percent year-on-year. The sharper figure is in global fund administration, where assets under management expanded 381.5 percent to $45.7 billion. As India’s listed universe grows with each new IPO cohort, KFin tech’s corporate registry and investor servicing business expands alongside it. Each new issuer represents a recurring service contract, not a one-time engagement, covering shareholder communications, annual report processing, and regulatory compliance. That makes its domestic revenue base structurally tied to the pace of primary market activity over time.

A sustained IPO wave reshapes capital markets well past the listing date. Demat accounts opened, SIPs initiated, mutual fund AUM accumulated, corporate registry mandates assigned: all of it routes through this layer of market infrastructure. Whether India’s forthcoming primary market cycle plays out over one year or three, BSE, CDSL, CAMS, and KFintech are where the structural demand settles first, and where its compounding shows up reliably on the income statement in the quarters that follow.
