World Sevens Football (W7F) confirmed the first four clubs competing in its inaugural tournament on Thursday, with Manchester United, Bayern Munich, Ajax, and Benfica joining the upstart's first competition this May.
Fashioned after tennis' Grand Slams, W7F is a series of tournaments, bringing together top clubs in major cities worldwide.
The debut three-day tournament will take place in the immediate lead-up to the May 24th 2025 UEFA Women's Champions League final, allowing the W7F launch to strategically capitalize on the excitement surrounding one of the sport's annual tentpole events.

W7F is the sport's latest 7v7 venture, with the US-based The Soccer Tournament spearheading the rise of the abbreviated game with its annual $1 million competition.
Like all future W7F contests, May's inaugural tournament will include a total of eight 7v7 clubs. Additionally, teams will compete in matches with two 15-minute halves, all on a field half the size of a full-team regulation soccer pitch.
In each W7F tournament, teams will vie for a share of a $5 million prize pool, with $2.5 million going to the champion while the runner-up banks $1 million.
As for the other four clubs joining the just-announced quartet in May, W7F is still negotiating with various teams, with the possibility of participation from non-European clubs still on the table.
A North American tournament is in the works for this fall, and W7F is also currently mapping out a four-year run-up to create five annual competitions across different continents.
