India’s ₹1 lakh crore club, classified by industry.

Every Indian company above ₹1,00,000 crore in market capitalisation or annual revenue, grouped into 11 sectors. 82 companies, each figure cross-checked against two independent sources on the same trading day.

Method, and what we will not claim

Market capitalisations are as at the close of 28 August 2026 and were taken independently from Screener.in and Groww. Where the two disagreed by more than 2% we recorded both rather than choosing the flattering one. Revenue is shown only where it independently clears ₹1 lakh crore.

Three cautions. Market caps move daily, so treat these as a dated snapshot rather than a live feed. Revenue is not comparable across sectors — for banks and insurers the figure is total income, which is a different measure from a manufacturer’s sales. And several companies sit within 15% of the threshold, so an ordinary market move takes them in or out.

We could not obtain exchange-primary quotes: NSE blocks automated access and BSE’s public endpoint returns classification data without market cap. Everything here therefore rests on two established data providers, not on NSE or BSE directly. We would rather say that than imply a precision we do not have.

82 companies, 11 sectors

Ordered by market capitalisation within each sector.

The conglomerate view

Ranked by the combined market capitalisation of listed group entities. Combined figures carry real caveats — holding structures double-count, and group boundaries are a judgement call. Each caveat is stated rather than smoothed over.

Large private companies, ranked on revenue

Market capitalisation does not apply here, so these are ordered on disclosed revenue. Several are frequently confused with a similarly named sibling entity — where that risk exists, it is spelled out.

Seven things most published lists still get wrong

Each of these was confirmed against filings, exchange intimations or company statements during compilation. All are recent enough that widely circulated directories still carry the superseded version.

Six places where two companies share one name

The commonest way a business directory becomes wrong is by summing two entities that describe the same revenue, or by attributing a listed company’s figures to its unlisted namesake.

Six names that changed while everyone kept using the old ones

Directories go stale here first. Each of these is a legal rename or demerger completed recently enough that most published lists still carry the superseded name.

These are not our clients. They are the benchmark our clients are measured against.

MNB Research builds AI systems for Indian SMEs, not for the companies on this list. We publish the list because the operating standard these firms set — instant response, 24/7 coverage, reconciled numbers — is the standard their smaller competitors are now judged by, usually without a comparable budget.

Each sector above maps to research and to products we already run. That mapping is the useful part of a directory like this.

Sources

Market capitalisation and revenue figures were taken independently from two providers on 28–29 August 2026 and reflect the 28 August 2026 close. Corporate actions were confirmed against company filings and press releases.

• Screener.in — company financials
• Groww — company profiles and market data
• LTM Limited — name-change intimation to the exchanges
• IBEF — sector data used across MNB Research

NSE and BSE primary quote endpoints were not accessible to automated retrieval, so no figure here is exchange-primary. Where our two sources diverged materially we recorded both. Figures are a dated snapshot, not a live feed.
