In a Land of Lavish Weddings, This Prenuptial Party Takes the Cake

When a member of one of India’s wealthiest families gets married, big-name guests and showstopping pomp and circumstance are nothing unusual. But it’s not every day that the invitees include royalty, business titans, Bollywood luminaries and Rihanna, for three days of a pre-wedding spectacular, months ahead of the actual ceremony.

The lavish festivities getting underway on Friday for Anant Ambani, whose father heads Reliance Industries, have seized public attention in India despite — or perhaps because of — how they underscore gaping inequality in a country that has enjoyed economic growth yet where millions still live in profound poverty.

Mr. Ambani, 28, the younger son of Mukesh Ambani, will welcome the guests at a sprawling venue in the western Indian state of Gujarat, along with his fiancée, Radhika Merchant. Ms. Merchant, 29, comes from a family that owns health care businesses and is trained in Indian classical dance.

The couple started the festivities earlier this week with a community feast: hosting thousands of people from neighboring villages and serving them Gujarati delicacies.

But for the main event starting Friday night, more than 1,000 guests, including some of the world’s richest people, are expected. Notable invitees include Bill Gates, Mark Zuckerberg of Meta and Bob Iger of Walt Disney; present and former prime ministers of Canada, Sweden and Qatar; the king and queen of Bhutan; and Bollywood stars Amitabh Bachchan, Shah Rukh Khan and Madhuri Dixit. Among the luxurious touches planned are chartered flights for the guests and people available to iron their clothes or help apply their makeup.

The guest list is part of the pageantry. Guests are not just (or not even) friends, but attractions in their own
