SEBI has approved the IPO of Indian Gas Exchange (IGX), India's first gas trading platform. The issue is entirely an offer for sale of 1.67 crore equity shares by promoter Indian Energy Exchange (IEX), meaning IGX itself receives no fresh capital. IGX facilitates spot and forward trading in natural gas, functioning as an exchange under petroleum sector regulation. The approval signals a potential listing that would make IGX a publicly traded gas market infrastructure entity.

Indian Gas Exchange (IGX) is India's first automated, digital natural gas trading platform, launched in 2020. It operates as a gas exchange where buyers and sellers trade natural gas through spot and forward contracts, similar to how IEX operates for electricity. IGX is a subsidiary of Indian Energy Exchange (IEX), which itself is a publicly listed exchange for electricity.

The IPO structure here is critical for exam purposes: it is a pure Offer for Sale (OFS), meaning existing shareholder IEX is selling its stake. No new shares are issued, so IGX gets zero proceeds — all money goes to IEX. This distinction between a fresh issue and an OFS is a recurring SEBI exam concept.

SEBI's role is to vet the Draft Red Herring Prospectus (DRHP) and issue observations (commonly called 'approval') before any company can proceed with an IPO. SEBI does not guarantee the quality of the issue — it only ensures disclosure norms are met.

For the broader gas market context: India's gas sector is regulated by PNGRB (Petroleum and Natural Gas Regulatory Board), while the exchange itself, as a securities market infrastructure, falls under SEBI's purview. Understanding which regulator governs which layer of a market — the commodity versus the exchange — is a classic SEBI exam distinction.
