InterGlobe Aviation (IndiGo) stock fell nearly 5% to ₹5,755 from ₹6,050 after co-founder Rakesh Gangwal's family announced selling a 3.1% stake worth around ₹7,000 crore via block deals. This stake sale continues the family's phased exit since 2022 amid governance disputes, causing market concern over promoter dilution despite IndiGo's operational strength.
