"Firstly congratulations to Max, he did a great job today," Hamilton said before the podium celebrations.
"It was such a tough race. Got a good start and gave it absolutely everything but at the end of the day they just had the upper hand this weekend."
Red Bull boss Christian Horner told Verstappen on the team radio after the victory: "Sheer class Max, that was classy. What a drive. What a drive".
He admitted after the race he was beyond nervous about the team's early stop strategy that ultimately decided the race.
Verstappen won the race by just 1.3 seconds.
The crucial moment may have been lap 54 when Hamilton was bizarrely 0.5 seconds slower, despite being on a charge with the fresher tyres.
