With Adani Group's surprise entry into the coveted 5G spectrum auction, Gautam Adani will be in direct competition with Mukesh Ambani as they later this month take part in the auction of airwaves able to provide fifth-generation (5G) telecom services. However, the competition between the two billionaire Gujarati businessmen will not yet be seen as a full-fledged market clash regardless of overlaps. Reliance Jio holds the maximum market share in the Indian telecom industry. The other two relevant players are Sunil Bharti-led Airtel and Kumar Mangalam Birla-owned Vodafone Idea Limited.
