Developing Twelve Fresh Accounts Called the Exact Ballon d'Or Top Five for $264,000. The Blockchain Found Them in Three Days. It Cannot Name Them.
French police are investigating, Groupe Amaury has filed a complaint, and a betting-analysis firm has traced three accounts to one wallet and a fourth to a Revolut cash-out. The case is the best evidence yet for the claim that prediction markets are transparent, and the best evidence yet that transparency is not enforcement.

Harry Kane won the Ballon d'Or at the London Palladium on October 26, the first Englishman in 25 years, ahead of Kylian Mbappé, Lamine Yamal, Rodri and Lionel Messi in that order. Three days before the ceremony, the French financial outlet Upside had already flagged that twelve Polymarket accounts, all created between October 1 and October 20, had staked about $264,000 on exactly that order. Seven of the twelve bet on nothing else. Six placed their first trade within fifteen minutes of being opened. The first withdrawal came nineteen minutes after the result was read out. The twelve collected about $200,000.
By Friday the case had a police unit, a complaint and a second forensic report. It still does not have a name.
What the chain shows
The second report, from the betting-analysis firm BETINT, is the one InGame's Daniel O'Boyle wrote up on Friday, and it is a good illustration of what public ledgers can and cannot do. BETINT found four accounts worth examining. Three of them drew funds from a single crypto wallet, which it treated as a shared source. A fourth was linked by nothing but timing, placing similar bets at similar moments. The four cleared $32,500 together. The three wallet-linked accounts still hold their winnings in crypto. The fourth rolled its proceeds into an NBA market, cashed out at roughly half its stake and withdrew to a Revolut account, whose know-your-customer file, BETINT notes, could identify the user. WellPlayed's read of Upside's earlier work found a similar thread: an account called kraben006, which bought Kane at 37 cents, sold at 67 and reinvested in the exact-position markets, moved money through a wallet associated with Deblock, a French financial app with its own identity records.
There is more in the ledger. A new account won $112,000 on Kane at an average price of 64 cents. An older account that had correctly called the 2024 and 2025 winners bought Kane one minute before voting closed. On October 9, with no news anyone can point to, the market on Mbappé finishing above Yamal moved from 27 cents to 46, and BETINT's linked accounts were 96% of the money on that side that day, about $6,000 in a market that barely traded.
Dan Zimmermann, BETINT's co-founder, put it carefully: "The fact they used a shared funding source suggests some attempt to obscure the trades," and the splitting across wallets looks like what "an amateur insider" would think of as concealment. He also noted the bets were smaller than certainty would justify, which could mean second-hand knowledge or an "internal conversation" rather than a copy of the results. BETINT's conclusion was that "it is likely they knew the result." Likely is the right word. Nothing here is proven, and France Football insists the winner was chosen by an independent vote.
Who is investigating, and what they can reach
Groupe Amaury, which has organised the award for 70 years, said on October 31 it was filing a complaint over "a possible leak of the results." France Football contacted the SCCJ, the police service responsible for gambling. The New York Times reported on November 4 that police were treating it as suspected insider trading. A French law-enforcement source told reporters that the way the accounts managed their positions also pointed that way.
Two facts about jurisdiction sit underneath all of this. First, Polymarket is blocked in France; the gambling regulator ordered internet providers to cut access in July, and the accounts, if French, were trading over a VPN. Second, Polymarket is, as NBC News described it in March, part-registered in the United States and part in Panama. Whichever side of that line these accounts sat on, a French police complaint about a French award reaches it only through the identity records of a payments app.
Polymarket's own rules, updated in March after the Iran-strike and Maduro episodes, prohibit trading on "stolen confidential information" and bar anyone holding "a position of authority or influence" over an outcome from trading it. Its chief legal officer, Neal Kumar, said then that "markets thrive on clarity." The company says it runs a "multi-layered monitoring system" and refers cases to law enforcement. We found no statement from Polymarket on the Ballon d'Or accounts in any of the reports we read, and two outlets said it had been asked. Whatever the monitoring system saw, Upside saw it first and published it before the ceremony.
The case for the ledger
The strongest argument on Polymarket's side is the one we would make for it: a sportsbook would never have let anyone see this. The reason Upside could flag the accounts on October 23, three days before the ceremony, and the reason BETINT could tie three of them to one wallet, is that every trade and every transfer is public. Compare the Clase pitch-rigging case now on trial in Brooklyn, where a DraftKings investigator testified on Thursday that his company had 160 geolocation pings from accounts at the pitcher's house, data nobody outside the company saw for two years. On a prediction market the amateurs are caught by other amateurs in days. That is a real property and we do not want to argue it away.
The same transparency also cuts against reading too much into it, and this week supplied the example. The Times reported on Friday that a single trader had put $622,608 on a Democrat in Michigan and $191,277 on Pete Ricketts in Nebraska shortly before Times/Siena polls were published. On Sunday The Block traced the account, dubdubdub2, through two years of history: a $1.05 million Mamdani position held to resolution, DeFi yield farming, a $783,000 loss on Hyperliquid in the 26 hours before the Senate bets, and a habit of trading at 3 a.m. Two academics who reviewed the data read it as a wealthy directional bettor, not a poll insider. Vincent Grégoire of HEC Montréal: "It's almost impossible to tell from the data." On-chain pattern-matching produces suspects. It does not produce cases, and sometimes the suspect is just rich and nocturnal.
Where that leaves the market
So grant the defence everything. Grant that the chain is more transparent than a book, that the twelve accounts might be a leak from a journalist's dinner rather than a copy of the count, that nothing is proven, and that the police complaint is the right venue for all of it. The argument that survives is about the market, not the traders.
An exact-order top-five market on an award decided by a jury of journalists, with the count finished before the ceremony, is a market whose result exists on paper, somewhere, while the contracts are still trading. That is not an information-aggregation problem. It is a leak with a price feed. Ben Schiffrin of Better Markets said in March that "insider trading regulation does not work if it is left to the platforms to police themselves," and the Ballon d'Or case is a cleaner test of that line than the Iran bets were, because here there is no national-security excuse for opacity and no US agency with a reason to look. The CFTC regulates Polymarket's American exchange. The French award, the French bettors and the offshore venue are, for the regulator, someone else's problem. For France Football, the venue is blocked and the complaint is against persons unknown.
What would move us: Polymarket publishing what its monitoring flagged and when, or the SCCJ naming a suspect from the Revolut or Deblock records. The first would show the "multi-layered system" works on something other than hindsight. The second would show that the ledger's trail ends somewhere. Until one of them happens, the twelve accounts are the strongest argument that prediction markets are transparent, and the strongest argument that transparent and policed are different words.
