He knew what was coming before the market discovered it.
Em Nova York, um engenheiro de segurança do Google com mais de uma década de casa foi preso por usar dados internos confidenciais para apostar em mercados de predição e acumular cerca de US$ 1,2 milhão em ganhos. Michele Spagnuolo explorou sua posição privilegiada dentro de uma das maiores empresas de informação do mundo para transformar conhecimento antecipado em vantagem financeira — uma transgressão que os mercados de predição, por sua própria natureza, não estavam preparados para detectar. O caso levanta uma questão mais ampla sobre o que acontece quando a assimetria de informação encontra sistemas projetados para funcionar apenas quando todos partem do mesmo ponto de partida.
- Spagnuolo tinha acesso ao fluxo bruto de dados de busca do Google antes que qualquer tendência se tornasse pública — e usou isso para apostar com precisão cirúrgica em resultados que já conhecia.
- Operando sob o pseudônimo 'AlphaRaccoon', ele movimentou US$ 2,7 milhões em apostas entre outubro e dezembro de 2025, apostando em nomes obscuros como D4vd enquanto o mercado apostava em celebridades conhecidas.
- A promessa de anonimato das criptomoedas falhou: transações em blockchain deixaram rastros públicos permanentes que o FBI usou para ligar múltiplas carteiras digitais a um documento de identidade italiano — o dele.
- Preso e levado a tribunal federal em Nova York, Spagnuolo foi solto após pagar fiança de US$ 2,25 milhões; o Google o afastou imediatamente e o Polymarket declarou cooperação com as autoridades.
- O caso expõe uma vulnerabilidade estrutural nos mercados de predição: eles dependem de equilíbrio informacional entre os participantes — e quando alguém de dentro entra no jogo, toda a lógica do sistema desmorona.
Michele Spagnuolo passou mais de uma década dentro da divisão de segurança do Google, observando padrões de busca se formarem antes de chegarem ao público. Em 2024, começou a usar esse acesso privilegiado para apostar no Polymarket, plataforma de predição que paga em criptomoedas. Quando as autoridades federais o alcançaram, ele havia acumulado cerca de US$ 1,2 milhão em ganhos.
O esquema era preciso. Usando materiais internos de marketing disponíveis a funcionários do Google, Spagnuolo antecipava quais termos e pessoas dominariam as buscas — e apostava contra o mercado. Enquanto outros apostavam em figuras como Bianca Censori ou Donald Trump como a pessoa mais buscada de 2025, ele colocou seu dinheiro em D4vd, um músico que mal aparecia nas odds. A aposta foi feita em novembro, quando Spagnuolo já sabia que D4vd — que havia ganhado notoriedade após ser preso sob suspeita de homicídio — liderava as buscas na plataforma.
Entre outubro e dezembro de 2025, ele movimentou cerca de US$ 2,7 milhões sob o pseudônimo 'AlphaRaccoon', circulando criptomoedas por diferentes carteiras digitais na tentativa de apagar o rastro. Mas o blockchain, por mais que prometa anonimato, registra tudo de forma permanente. O FBI rastreou as carteiras até uma conta vinculada a um documento de identidade italiano — pertencente a Spagnuolo.
Detido numa quarta-feira e apresentado ao tribunal federal de Nova York, o engenheiro — cidadão italiano residente na Suíça — foi liberado após pagar fiança de US$ 2,25 milhões. O Google o afastou imediatamente, classificando o uso dos materiais internos como uma grave violação de política, ainda que os documentos em si fossem de circulação rotineira entre funcionários. O Polymarket declarou cooperação com as investigações.
O caso ilumina uma fragilidade estrutural dos mercados de predição: eles funcionam sob a premissa de que os participantes partem de bases informacionais semelhantes. Spagnuolo não apostava no futuro — apostava no presente que só ele enxergava. A ironia não passa despercebida: um especialista em segurança da informação, contratado para proteger dados, usou exatamente esse acesso para enriquecimento próprio. O processo segue na Justiça federal americana, e a pergunta sobre como regular a interseção entre informação privilegiada e mercados de predição permanece, por ora, sem resposta.
Michele Spagnuolo had access to something most people will never see: the raw data flowing through Google's search infrastructure. For more than a decade, he worked in the company's security division, watching patterns emerge before they became public knowledge. In 2024, he began placing bets on Polymarket, a prediction platform that pays out in cryptocurrency. By the time federal authorities caught up with him, he had turned that access into approximately $1.2 million in winnings.
The mechanics of the scheme were straightforward enough. Spagnuolo used confidential marketing materials available to Google employees to anticipate which search terms would trend, which people would dominate the platform's attention. Then he bet against the crowd. When everyone else was wagering that celebrities like Bianca Censori or President Donald Trump would be Google's most-searched person in 2025, Spagnuolo placed his money on D4vd, a musician whose name barely registered on the betting odds at the time. He made that bet in November, according to court documents, already knowing that D4vd had become the top search result across Google's platforms. The musician, who had recently gained notoriety, was imprisoned on suspicion of murdering a teenager.
Between October and December of 2025, Spagnuolo moved roughly $2.7 million through Polymarket's system. He operated under the handle "AlphaRaccoon," cycling cryptocurrency through different digital wallets in an attempt to obscure the trail. But blockchain transactions, for all their promise of anonymity, leave permanent public records. The FBI, working with the U.S. Attorney's Office for the Southern District of New York, traced the wallets back to a single point of origin: an account registered with an Italian identity document. That document belonged to Spagnuolo.
He was detained on a Wednesday and brought before federal court in New York. The charges centered on violations of insider trading laws—using material nonpublic information to place bets, essentially. Spagnuolo, an Italian citizen living in Switzerland, was released after posting a $2.25 million bail. Google moved quickly to distance itself from the conduct, placing him on leave and issuing a statement that the marketing materials he had accessed were routine internal documents, but that using them for personal betting constituted a grave breach of company policy. Polymarket, the platform where the bets were placed, said it was cooperating with investigators.
The case exposes a peculiar vulnerability in the modern financial ecosystem. Prediction markets have grown into a significant corner of the digital economy, attracting billions in wagered value. They operate on the assumption that dispersed information and open betting will produce accurate forecasts. But that system depends on participants operating from roughly equal informational footing. When someone with access to proprietary data enters the market, the entire premise collapses. Spagnuolo had spent twelve years inside one of the world's largest information companies, watching data move before it reached the public. He knew how to read the signals. He knew what was coming.
The investigation revealed the granular details of his betting patterns. He wagered against popular figures and toward obscure ones. He timed his bets with precision. The court documents suggest a person who understood not just what would happen, but when the market would discover it. He was, in effect, trading on the gap between what he knew and what everyone else believed.
Neither Spagnuolo nor his legal representatives responded to requests for comment from American media outlets. His professional profiles show a career built on information security—the very discipline meant to prevent exactly this kind of breach. The irony is sharp: a man hired to protect data used it to enrich himself. The case now moves through federal court, with the question of what happens when insider access meets prediction markets still largely unanswered.

How did the FBI actually connect the dots? Cryptocurrency is supposed to be hard to trace.
It wasn't the cryptocurrency itself that gave him away—it was the registration. One wallet was tied to an Italian ID document. That single anchor point let them unwind the whole network.
So he made a fundamental mistake. He got lazy on one account.
Or he thought one legitimate registration wouldn't matter if the others stayed anonymous. But blockchain doesn't forget. Every transaction is permanent and visible. The FBI just had to find the thread.
What strikes you most about the D4vd bet?
That he knew before the market knew. He placed money on someone with almost no odds, then that person became the top search result. He wasn't predicting—he was reporting. He already had the answer.
Did Google know what he was doing?
No indication of that. They found out when the FBI showed up. But the fact that he had access to these materials at all—that's on them. He was in security. He had clearance.
What does this mean for prediction markets going forward?
It means they're only as fair as the information asymmetry allows. If insiders can access data before the public, the market becomes a casino where one player sees the cards. That's not prediction—that's theft.
