In Mumbai, the party began before the stock market listing.
Social media posts show large-scale private gatherings held at the Reliance Corporate Park near Mumbai this week, which included dozens of food stalls serving Indian street food, dance performances and jam sessions blending devotional music with contemporary rhythms.

"Given the Ambani family's unique wedding celebrations, its IPO festivities are also expected to be out of the ordinary," said Ambareesh Baliga, an independent market analyst in Mumbai.
