The Rotterdam Open dates to the early 1970s, with Arthur Ashe taking the inaugural singles title before the event settled at the Rotterdam Ahoy arena. The indoor hard-court ATP 500, established in 1974, has been staged at Rotterdam Ahoy in the Netherlands ever since, and after years on carpet it switched to indoor hard courts in 1999 to fall in line with ATP standardization. Slotted in the early-February window just after the Australian Open, it stands as the season's first event at the 500 tier — the entry point to the European indoor swing rather than a fall finale like Vienna or Basel.
The character is pure indoor: a fast, true bounce under the Ahoy roof, no weather variables, and a tournament built as a full-week spectacle. The ABN AMRO Open is unusual in that wheelchair tennis is integrated into the same arena in the same week; the tournament has hosted it since 2009 and grown into the largest indoor wheelchair event in Europe. Directed by former Wimbledon champion Richard Krajicek, it routinely draws record Dutch crowds — attendance surpassed pre-pandemic figures of roughly 120,000, reaching 126,963 visitors in 2024.
The honour roll runs deep. Roger Federer holds the record for most singles titles with three, the last as a 36-year-old in 2018 — the tournament's oldest champion. The recent era reads like a who's-who of the new top tier: Daniil Medvedev won in 2023 over Jannik Sinner, Sinner took the 2024 crown over [Daniil Medvedev], and Carlos Alcaraz captured the 2025 title, his first on indoor hard. Alex De Minaur, a two-time finalist in 2024 and 2025, finally broke through to lift the trophy at the 2026 edition over Felix Auger-Aliassime, 6-3, 6-2.
The event remains commercially robust. As of February 2025, ABN AMRO extended its title sponsorship through the 2028 edition, and the 2026 prize pool climbed to roughly €2.46 million, with the singles winner banking €460,555 and 500 ranking points.
