The Met Gala has outdone itself, even before it’s begun.

The annual gala at the Metropolitan Museum of Art — the flashy fashion extravaganza that highlights the city’s social scene every May — is expected to raise more than $31 million this year, the biggest gross in the event’s 77-year history.

The money haul — and the avid interest the gala inspires — further cements its place as the pre-eminent benefit among the city’s cultural institutions, and one the world’s most sought-after tickets. The Met’s take dwarfs events like a September gala for the New York Philharmonic (which brought in nearly $4 million) and the 2024 event for the Whitney Museum of American Art, which raised some $5.2 million.

The $31 million figure does not reflect the seven-figure cost of staging the gala, which will kick off on Monday evening with the procession of pop stars, fashion icons and sporting-world superstars striding the red carpet, enduring countless flashbulbs, and surrounded by a swarm of publicity and eager onlookers.

The gala will act, as always, as the opening of a Costume Institute exhibition: This year’s is entitled “Superfine: Tailoring Black Style,” examining 300 years of Black fashion and the vibrant history of Black dandyism.

That emphasis is a significant departure from the department’s largely monochromatic past: This is the Met’s first fashion exhibition devoted entirely to designers of color, and is being seen as part of a larger effort to diversify the collection. It is also a rarity for its focus on men’s wear.

As such, it drew an array of Black celebrities to help host the event — including Colman Domingo, Lewis Hamilton, ASAP Rocky and Pharrell Williams. LeBron James, whose Los Angeles Lakers were bounced from the N.B.A. playoffs last week, is the honorary chair.
