Ukrainian President Volodymyr Zelenskyy’s attire at a June 24 NATO summit in the Netherlands has sparked a heated debate among users of Polymarket, a crypto-based prediction platform.
The controversy centers around a market asking whether Zelenskyy would wear a suit before July. For the bet to be settled, there must be photo or video evidence of him wearing a suit between May 22 and June 30.
The market attracted nearly $79 million in trading volume. Though it was initially resolved in favor of “yes,” the outcome has been challenged twice and is now pending a final ruling.
On July 1, Polymarket acknowledged the dispute, stating that “a consensus of credible reporting has not confirmed that Zelenskyy has worn a suit.”
Arguments over what makes a suit
The debate over Zelenskyy’s outfit has ignited a flurry of discussion on social media, with users dissecting whether he was actually wearing a suit, a coordinated blazer with a collared shirt and trousers, or if his choice of footwear disqualifies the look altogether.
Supporters of the “suit” classification argue that the outfit is made of matching fabric, features a consistent color palette, and maintains a formal appearance—suggesting that specific cuts or footwear shouldn’t matter.
Critics, however, contend that Zelenskyy wore a black shirt and a black jacket resembling a casual blazer rather than a classic suit jacket. They also point to his trainers, arguing the casual shoes break the formal continuity, meaning it doesn’t meet the standard definition of a suit.
A community-run X (formerly Twitter) account, Polymarket Intel, declared the outfit a suit. But when consulted ChatGPT, it disagreed—describing the ensemble as a military-style field jacket or tactical coat, not a traditional suit.
Meanwhile, Canadian men’s fashion writer and commentator Derek Guy—known as the “menswear guy” on X—added to the ambiguity rather than resolving it. On June 26, he weighed in by saying he believes Zelenskyy’s outfit is “both a suit and not a suit.”
Second time’s the charm
This isn’t the first time Zelenskyy’s wardrobe has stirred controversy on Polymarket. A similar betting market, which closed on May 31, triggered debate over whether an outfit he wore during a meeting in Germany that month qualified as a suit.
Polymarket ultimately ruled that the outfit did not count as a suit. However, fashion expert Derek Guy chimed in again, stating that Zelenskyy was technically wearing a suit—citing the definition as “a garment where the jacket and pants have been cut from the same cloth.”
Zelenskyy has faced criticism in the past for opting not to wear a suit during formal meetings with world leaders.
However, as Politico reported on March 22, Zelenskyy has said he won’t return to wearing suits until the war with Russia is over.
A March 5 report from Ukrainian outlet The Kyiv Independent echoed this sentiment, explaining that the president intentionally chooses a more casual, military-style outfit to reflect the ongoing conflict—adding that “if he puts on a suit, it means he agrees that the war is over.”
Polymarket controversy
Polymarket has found itself at the center of several controversies this year, including a heated dispute in January over the proposed TikTok ban. In that case, bettors clashed over whether the outcome met the conditions—TikTok was technically banned, but still accessible when the market closed.
To resolve such bets, Polymarket relies on blockchain oracles from the UMA Protocol, which pull in external data to verify real-world events and determine outcomes. However, UMA has faced criticism and accusations of being manipulated or acting unpredictably. One notable example was a $7 million betting market in March tied to a Ukrainian mineral deal, which drew allegations of oracle tampering.
On Thursday, blockchain-based economic database Truf.Network released a report highlighting the deeper issue: verifying truth in decentralized markets is inherently difficult. The report noted that outcomes often depend on fragmented, unverifiable, and potentially manipulated data.
“It’s not about who decides the truth, but whether everyone can verify it,” the report stated. “When no one can verify a price, who won, what the score was, or even if it rained yesterday, the market itself collapses.”
It added, “If the person verifying the outcome is also betting on the game, truth becomes debatable.”
