Mondo Duplantis suffers shock home defeat as Marschall ends 40-meet winning streak

The aura of invincibility surrounding Armand 'Mondo' Duplantis finally cracked on Sunday, as the Swedish superstar was beaten in the pole vault for the first time in nearly three years — and in front of his own adoring home crowd at the Stockholm Diamond League.

Australia's Kurtis Marschall produced the performance of his life to claim a maiden Diamond League title, clearing 5.90 metres to deny the multiple world-record holder and end an extraordinary streak of 40 consecutive victories stretching back to July 2023.

It was a result that stunned the Stockholm stadium and sent shockwaves through the athletics world, a rare off-day for a competitor who has rewritten the record books and redefined what is possible in his event.

The night the streak ended

Duplantis cleared 5.80 metres but then faltered at the heights that have become routine for him, failing twice at 6.00m and once at 6.05m. With the Swede unable to go clear, Marschall's 5.90m proved enough to seal a famous victory.

The defeat was Duplantis' first since a loss in Monaco in July 2023, an astonishing run of dominance that had seen him win virtually everything in sight, including Olympic gold and a long succession of world records. For once, however, the bar refused to stay up.

Marschall, by contrast, kept his composure throughout, clearing his heights cleanly and capitalising the moment the door cracked open. Knowing that one good clearance might be enough, the Australian held his nerve under the kind of pressure that has undone so many in the past, and his celebration as he secured the win spoke to years of near-misses behind the great Swede.

“Beating Mondo, here in Stockholm of all places, is something I'll never forget. I'm going to take it and run — this is the confidence boost I've been chasing for years.”

A rare human moment for the great Swede

Duplantis has set such impossibly high standards that even a clearance of 5.80m felt like an aberration. The Swede has made a habit of saving his best for the biggest occasions, and a home crowd had arrived expecting another assault on his own world record rather than a defeat.

Yet the loss, far from diminishing him, served as a reminder of how relentless his standards have been. Streaks of 40 victories are almost unheard of in any individual sport, and even the greatest competitors are entitled to an occasional off-night.

Why the result matters

Marschall's win is more than a one-off shock; it injects fresh jeopardy into a discipline that had threatened to become a procession. With a global championship season approaching, the result suggests the Australian is closing the gap on the sport's dominant figure.

• Marschall won with a clearance of 5.90m
• Duplantis managed 5.80m but failed at 6.00m and 6.05m
• The defeat ended a 40-meet winning streak dating back to July 2023
• It was Duplantis' first loss since a defeat in Monaco in 2023

For Marschall, the victory is a long-awaited reward for years of consistency just below the very top, and a statement that the pole vault may finally have a genuine rivalry to savour.

It also matters for the wider health of the event. A discipline carried for years by a single transcendent star benefits enormously from a credible challenger, and the prospect of Duplantis being pushed all the way at the sport's major meetings can only add to the drama. Sunday's result, however isolated it may yet prove, gives the pole vault a narrative beyond one man chasing his own records.

Background

Duplantis, who competes for Sweden but was raised in Louisiana, has been the defining figure of his event for years, breaking the world record on numerous occasions and clearing heights once thought unattainable. His showmanship and consistency have made him one of athletics' biggest draws and a guaranteed highlight of any Diamond League programme.

Marschall, a former world indoor medallist, has long been among the leading challengers but had never managed to topple the Swede on the Diamond League circuit. Doing so in Stockholm, the scene of some of Duplantis' greatest triumphs, made the achievement all the more remarkable.

What happens next

Duplantis will be eager to reassert his dominance at the next Diamond League stop, and few expect his stumble to mark the start of any genuine decline. But Marschall has shown the rest of the field that the Swede is beatable, and a discipline that had become a one-man show suddenly has a compelling new storyline heading into the heart of the season.
