01Two businesses
India's oil and gas producer — and a refiner too
Oil and Natural Gas Corporation is India's largest producer of crude oil and natural gas, majority-owned by the Government of India. Its overseas arm, ONGC Videsh, holds oil and gas assets in other countries.
Three businesses under one share price
Reliance Industries started out in textiles and petrochemicals and is now India's most valuable listed company. Its oldest engine, oil-to-chemicals (O2C), runs the Jamnagar refining complex and turns crude oil into fuels, polymers and polyester. Profits there rise and fall with global refining margins, which is why the segment is valued as a capital-heavy commodity business.
02The records side by side
On revenue the two have grown at much the same pace: ONGC compounded at about 8% a year (FY2018–FY2026) and Reliance Industries at about 9% (FY2019–FY2026). By revenue, Reliance Industries is about 1.6 times the size of ONGC. ONGC kept 7.5% of revenue as net profit in FY2026; Reliance Industries kept 8.9% of revenue as net profit in FY2026.

03What each price assumes
Work backwards from each share price and you can see what buyers are taking for granted — the rate each company must sustain to justify what it costs, against what its own record supports.
04What decides each one's value
- Crude oil pricesHigher prices lift ONGC's realisations, though government levies have capped the gains in the past.
- Production volumesMany fields are mature; new deep-water projects need to offset natural decline.
- Jio's revenue per userThe network is already built, so each tariff increase drops almost straight to profit. How far revenue per user can rise without losing subscribers is the biggest single swing factor in the group's value.
- Retail's store economicsRetail is worth what each store earns once it matures, not how many stores open. Slower same-store growth would shrink this part of the valuation faster than any other.
05What could go wrong
- Government interventionWindfall taxes and pricing controls have taken away upside before.
- Field declineWithout new discoveries, output falls year after year.
- The holding-company discountMarkets often value conglomerates below the sum of their parts, and that discount can last for years.
- New energy is still a betThe solar, battery and hydrogen projects are early, capital-hungry and not yet proven at scale.
