Alcaraz will open his title defense later in the week against the winner of the first-round clash between American rising star Ben Shelton and Argentine clay specialist Francisco Cerundolo. The most anticipated storyline of the 2026 event is the farewell run of 14-time Barcelona champion Rafael Nadal, who confirmed last month that 2026 will be his final professional season. Nadal has been placed in the bottom half of the draw and will play his first-round opener on Tuesday, April 14 against a qualifier to be determined over the weekend of qualifying matches. The April 13 Day 1 schedule includes 16 first-round men's singles matches and 8 first-round men's doubles matches across 7 competition courts. The iconic Pista Central will open at 11:00 AM local time, with the first match pitting former top-10 player Casper Ruud of Norway against French wild card entry Hugo Gaston, followed by a matchup between 12th seed Alejandro Davidovich Fokina of Spain against Australian qualifier Max Purcell. The third and final match on Center Court will see 2023 Barcelona finalist Stefanos Tsitsipas of Greece take on Spanish veteran Roberto Bautista Agut, scheduled to start no earlier than 6:00 PM local time to accommodate prime-time broadcast audiences across Europe, Latin America and North America. Outer courts will also host high-stakes matches, including a clash between former world No. 3 Dominic Thiem and 18th seed Lorenzo Musetti on Pista 1 at 12:00 PM local time, and an all-Spanish matchup between wild card Pablo Carreno Busta and qualifier Jaume Munar on Pista 2 at 1:30 PM local time.

Tournament director Albert Costa noted in a pre-event press conference that the 2026 edition features 18 of the world's top 25 players competing for the €2.8 million total prize pool and the iconic Conde de Godo trophy.
