Jio IPO grey market premium points to 22% listing gain

Ahead of Jio Platforms' October 28 stock market debut, its grey market premium has held at about 22% over the IPO price for roughly 10 days, unusually steady for a $3.1 billion issue. If that holds, Mukesh Ambani's telecom and digital firm would become India's second most valuable company after parent Reliance Industries, overtaking Bharti Airtel.
