The Indian Gas Exchange (IGX), a platform for natural gas trading, plans to launch an Initial Public Offering (IPO) by December 2026. The IPO, an offer for sale by existing shareholders, is expected to raise Rs 600-700 crore through the sale of approximately 22% equity. This move is partly driven by regulatory requirements for its parent company, Indian Energy Exchange (IEX), to reduce its stake. IGX also plans to introduce longer-term contracts on its platform.
