Second place went to Canada's Eric Lamaze on stallion Hickstead in 36.51 seconds, earning 57,000 euros.
Third place went to Germany's Marco Kutscher on stallion Cornet Obolensky, picking up 38,000 euros for his 37.40-second performance.
The overall leader in the Tour, Belgium's Patrick McEntee, sat the Rio leg out. He has a comfortable margin over the next closest rider in the competition, Germany's Meredith Michaels-Beerbaum, who was also absent.
After Rio, the GCT goes to the Dutch town of Valkenswaard later this month before wrapping up with the finals in November in Doha, Qatar.
Athina Onassis, the 24-year-old multi-millionaire patron of the show bearing her name, was photographed casually riding with Charlotte Casiraghi, fourth-in-line in Monaco's princely dynasty, and fellow horse-lover.
