The Campeonato Argentino Abierto de Polo is the Super Bowl of polo. Thirty thousand people pack into the Campo Argentino de Polo in Buenos Aires while the rest of the polo world watches from wherever they can find a screen. Known universally as the Palermo Open, this is the third and final leg of the Argentine Triple Crown, and winning it is the single greatest achievement the sport offers. No other polo tournament on earth approaches its intensity, its history, or its atmosphere. The 2026 edition, the 133rd, begins October 31 and builds toward an estimated final on December 6.
The Argentine Open operates at the 40-goal handicap with 8-chukker matches, a standard that exists nowhere else. Eight chukkers instead of six means longer matches, deeper horse strings, and a gruelling test of stamina and depth that separates the great teams from the merely good. The pressure of playing at 40 goals is immense: every player on the field is rated 9 or 10, the best in the world, and the margin for error is essentially zero.
The 2026 field reads like a who’s who of the sport. La Natividad La Dolfina enters at a perfect 40 goals: Adolfo Cambiaso, the greatest player in history at 50 years old, playing alongside his 22-year-old son Poroto Cambiaso and the Castagnola brothers, Camilo and Barto. A father and son, two brothers, four 10-goalers, the maximum possible rating. Their main challengers include Ellerstina Indios Chapaleufu (36 goals) with the Pieres brothers, Facundo and Gonzalito, carrying decades of rivalry with La Dolfina. Las Monjitas (35 goals) bring Juan Martin Nero, holder of the all-time record with 12 Argentine Open titles, alongside David Stirling, the only non-Argentine 10-goaler in modern polo. La Irenita (34 goals), anchored by Pablo Mac Donough, and La Hache (34 goals), captained by Hilario Ulloa, round out a field that carries more combined major titles than any other annual sporting event.
The storyline that hangs over the 2026 Argentine Open is Cambiaso. At 50, playing with his son at the highest level of the sport, every final could be his last. The crowd at Palermo knows this. When he rides onto the field, 30,000 people understand they may be watching the end of an era that has lasted more than three decades. The Cambiaso-Nero rivalry, which defined a generation of Argentine Opens through their years together at La Dolfina, now plays out on opposite sides. Nero, with his record 12 titles, facing the man he won most of them alongside.
For fans watching from outside Buenos Aires, the timezone is straightforward. Buenos Aires runs at UTC-3 year-round with no daylight saving. The estimated final on December 6 at 16:30 local time translates to 19:30 in London, 20:30 in Central Europe, and 14:30 in New York, all comfortable viewing slots. For fans in Tokyo, the 04:30 start the following morning means setting an alarm or catching highlights. For Australian viewers in Sydney, the 06:30 AEDT start is early but manageable.

The atmosphere on final day at Palermo is unlike anything else in polo. Buenos Aires in early December is deep spring, warm and bright, and the city turns its attention to the Cathedral. The stands fill hours before the first throw-in. The noise builds through the match. When the final bell sounds, the winning team does a victory lap on horseback while the crowd roars. It is the greatest single day in polo’s calendar, played at a venue that earned its nickname for a reason.
Exact semi-final and final dates are typically confirmed mid-season. Following the Hurlingham Open in September-October and the Tortugas Open in October, the Argentine Open is where the season, and possibly the Triple Crown, is decided.
