一名谷歌软件工程师因涉嫌利用公司机密信息在Polymarket平台下注，获利超过120万美元，面临联邦指控。这是近几个月来针对这家热门预测市场服务用户的第二起内幕交易起诉案。
根据司法部公布的法庭文件，米凯莱·斯帕尼奥洛被控于去年年底使用公司内部工具查询谷歌2025年热门搜索数据。随后，在谷歌通过年度年度搜索报告公开相关信息数周前，他据称在Polymarket上下注数百万美元，赌多位名人是否会跻身当年谷歌搜索量最高的人物榜单。
2025年搜索量最高的人物最终是歌手D4vd，去年一名15岁少女的肢解尸体在一辆登记在他名下的汽车后备箱中被发现后，他引发了全国关注。斯帕尼奥洛使用用户名“AlphaRaccoon”在Polymarket下注，在市场普遍认为D4vd上榜概率极低的情况下，他精准押注D4vd会进入搜索量最高人物榜单，获利数百美元。
在年度搜索数据公开数日后，斯帕尼奥洛的Polymarket账户据称将数百万美元加密货币转移至一个加密钱包。
斯帕尼奥洛被控商品欺诈、电信诈骗和洗钱。商品期货交易委员会也以类似理由对其提起民事诉讼。
针对居住在瑞士的意大利公民斯帕尼奥洛的指控于周三公开。美国纽约南区检察官办公室向哥伦比亚广播公司新闻证实，他于周三在纽约被捕，并在地方法官面前以225万美元保释金获释。
哥伦比亚广播公司新闻已联系斯帕尼奥洛及其律师置评。
谷歌发言人表示，斯帕尼奥洛已被停职，这家科技巨头正与执法部门合作。
“该员工使用了所有员工都可使用的工具访问我们的营销材料，但利用此类机密信息下注严重违反了我们的政策，”该发言人说道。
Polymarket在X平台上表示，该交易员已被平台标记。一位发言人表示，公司与联邦当局密切合作，称Polymarket是“迄今为止美国首个因合作促成内幕交易指控的预测平台”。
就在斯帕尼奥洛被控案发生一个月前，一名美国特种部队士兵因涉嫌在突袭抓捕委内瑞拉前领导人尼古拉斯·马杜罗的消息公开前下注获利超40万美元而被捕。该士兵已不认罪。
这两起案件凸显了人们对预测市场上可能发生内幕交易的担忧，近年来这类平台的人气急剧上升。今年早些时候，一名数据分析师在接受《60分钟》采访时表示，他发现其他Polymarket账户通过精准押注美国军事行动获利数百万美元，有时胜率高得令人难以置信。
Polymarket表示，其平台禁止内幕交易，并会监管不当行为，将违法行为移交联邦当局。
“区块链交易具有透明性和可追溯性，不良行为者会留下痕迹，”该公司发言人说道。“我们致力于维护准确、公平、透明的市场，同时执行我们的规则，并与监管机构和执法部门合作。”
Google employee accused of making over $1.2M on Polymarket through insider trading
May 27, 2026 / 11:00 PM EDT / CBS News
A software engineer at Google is facing federal charges after allegedly betting on confidential company information on Polymarket, netting more than $1.2 million in profits, the second insider trading prosecution against a user of the popular prediction market service in recent months.
In court papers released by the Justice Department, Michele Spagnuolo was accused of using an internal company tool late last year to look up data on Google’s top-trending searches of 2025. He then allegedly placed millions in bets on Polymarket on whether or not various celebrities would rank among the most searched people on Google that year, weeks before the company released that information publicly in its annual Year in Search report.
The most widely searched person of 2025 ended up being D4vd, a singer who drew nationwide attention last year after a 15-year-old’s dismembered body was found in the trunk of a car registered to him. Using the Polymarket username “AlphaRaccoon,” Spagnuolo was accused of correctly betting hundreds of dollars that D4vd would show up in the most widely searched people, at a time when the market assessed the odds of D4vd appearing as fairly slim.
Days after the Year in Search data was publicly announced, Spagnuolo’s Polymarket account allegedly transferred millions of dollars in cryptocurrency to a crypto wallet.
Spagnuolo was charged with commodities fraud, wire fraud and money laundering. The Commodity Futures Trading Commission also sued him in civil court on similar grounds.
The charges against Spagnuolo, an Italian citizen who lives in Switzerland, were unsealed on Wednesday. He was arrested in New York on Wednesday and appeared before a magistrate judge who released him on $2.25 million bond, the U.S. Attorney’s Office for the Southern District of New York confirmed to CBS News.
CBS News has reached out to Spagnuolo and his attorney for comment.
A Google spokesperson said Spagnuolo has been placed on leave, and the tech giant is working with law enforcement.
“The employee accessed our marketing material using a tool available to all employees, but using such confidential information to place bets is a serious breach of our policies,” the spokesperson said.
Polymarket said on X that it flagged the trader. A spokesperson said the company worked closely with federal authorities, calling Polymarket “the only prediction platform to date whose cooperation has led to insider trading charges in the United States.”
The charges against Spagnuolo came one month after a U.S. special forces soldier was arrested for allegedly winning over $400,000 by betting on the raid to capture former Venezuelan leader Nicolás Maduro before news of the raid was made public. The soldier pleaded not guilty.
The cases have highlighted concerns about the potential for insider trading on prediction markets, which have surged in popularity in recent years. Earlier this year, a data analyst told “60 Minutes” he has spotted other cases of Polymarket accounts raking in millions by correctly betting on U.S. military operations, sometimes achieving an unbelievably high win rate.
Polymarket has said insider trading is prohibited on its platform, and it polices misconduct and refers illegal acts to federal authorities.
“Blockchain trading is transparent, traceable, and bad actors leave footprints,” the company spokesperson said. “We are committed to maintaining accurate, fair, and transparent markets as well as enforcing our rules and working with our regulators and law enforcement.”
