Duplantis came to Tokyo as a big favorite and lived up to everyone's expectations.
The Swede has dominated pole vault for the past two years and is the only one who has managed six meters so far this summer.
In the Olympic final in the Japanese capital, the entrance height was 5.55 and Duplantis managed it by a ridiculous margin.
He looked to fly a meter over the crossbar.
- It's among the sickest I've seen!
A shock opening.
I have never seen a jump with a larger margin at those heights, says SVT's expert Alhaji Jeng.
Injured Lavillenie cried openly
At the same time, rival Renaud Lavillenie competed injured, with both feet wrapped, after a miss on the warm-up where he landed heavily with his feet first.
Lavillenie went in at 5.70, passed it on the first try, and then cried openly in front of the TV cameras.
He limped between jumps and then stood over until 5.87 where he made an attempt, but interrupted and grinned badly.
Before Duplanti's second jump - at 5.80 - it had started to blow, but there was nothing that seemed to affect "Mondo" which was high above.
When the bar was raised to 5.92, four jumpers remained.
Duplantis, Lavillenie, brass Thiago Braz and American Christopher Nilsen.
Lavillene had two chances, of which the first attempt was really good, but the pain was simply too much.
At the same time, Duplantis continued to impress and managed seemingly easily in the first attempt.
Nilsen managed in second and Braz tore himself out, but snatched the bronze.
Nilsen set a new personal best
The battle for the gold was thus between Duplantis and Nilsen, who surpassed himself and put the personal best, 5.97, in the first attempt.
The answer from Duplantis?
A monster jump where he was high, high above the bar.
Then a gesture with his hands towards the stands as if to say "take it easy".
Nilsen made three attempts at 6.02 but was never really close and Armand Duplantis, who is still faultless, has thus secured the Olympic gold even though he will continue to jump on his own and chase the world record.
The medal is Sweden's fifth at the Games in Tokyo.
In total, there have been two gold and three silver.
