<p class="is-style-lead">Polymarket has referred nearly 100 suspicious crypto wallets to law enforcement as the prediction market platform expands its monitoring of possible insider trading.</p><div id="cn-block-summary-block_fb520a7b2b4957fa848616fd14a462f6" class="cn-block-summary"><div class="cn-block-summary__nav tabs"><span class="tabs__item is-selected">Summary</span></div><div class="cn-block-summary__content"><ul class="wp-block-list"><li>Polymarket referred nearly 100 suspicious wallets to authorities as insider-trading concerns grew across prediction markets.</li><li>Bloomberg analysis found about $200 million in flagged trades, concentrated heavily in geopolitical prediction markets.</li><li>Recent prosecutions involving Venezuela and Google-linked wagers have increased scrutiny of nonpublic information misuse cases.</li></ul></div></div><p>The referrals come as a <a href="https://www.bloomberg.com/graphics/2026-polymarket-traders-who-knew-the-future/?srnd=phx-crypto" rel="noopener noreferrer nofollow">Bloomberg analysis</a> of Polysights data found that about $200 million in Polymarket trades during the first half of 2026 showed characteristics associated with “potential insider activity.”&nbsp;</p><p>Much of the flagged activity involved geopolitical markets tied to Iran and Venezuela. The data does not prove that every flagged trade involved illegal conduct, but it shows the volume of activity now facing closer review as prediction markets draw more regulatory attention.</p><p>You might also like: <a href="https://crypto.news/hashkey-taps-kbank-bpmg-in-south-korea-stablecoin-payments-push/" rel="noopener noreferrer nofollow"> HashKey taps Kbank, BPMG in South Korea stablecoin payments push </a></p><h2 class="wp-block-heading" id="strong-polymarket-expands-surveillance-as-suspicious-trades-rise-strong"><strong>Polymarket expands surveillance as suspicious trades rise</strong></h2><p>Polymarket Chief Legal Officer Neal Kumar said the company’s internal process had resulted in nearly 100 wallet referrals to authorities. The platform has also strengthened surveillance as regulators examine whether traders may have used confidential information to gain an advantage in event contracts. Because Polymarket records transactions on a public blockchain, investigators can trace wallet activity, funding flows and trading patterns even when users trade through pseudonymous addresses.</p><figure class="wp-block-embed is-type-rich is-provider-x wp-block-embed-x"><div class="wp-block-embed__wrapper"><blockquote class="twitter-tweet"><p>Polymarket Refers Nearly 100 Suspicious Wallets to Law Enforcement<br><br>Polymarket said it has strengthened its insider-trading surveillance and referred nearly 100 suspicious wallets to law enforcement.

Analysts can examine signals such as newly created wallets, unusually concentrated positions and trades placed shortly before major events.&nbsp;</p><p>Those signals can direct attention toward accounts that deserve further review. However, a “suspicious” label does not establish insider trading, and a referral does not mean authorities will file charges.</p><p>In addition, the growing scrutiny follows a U.S. case involving Army Master Sergeant Gannon Ken Van Dyke. As previously reported by crypto.news, the Department of Justice <a href="https://crypto.news/us-soldier-faces-doj-charges-over-maduro-prediction-bets/" rel="noopener noreferrer nofollow">accused</a> Van Dyke of using classified information about a U.S. military operation targeting Venezuelan President Nicolás Maduro to place Polymarket trades. Prosecutors said he made about $409,881 after placing more than $33,000 in bets linked to Maduro’s removal.</p><p>The CFTC filed a parallel case, while the Justice Department brought charges tied to the alleged use of classified information. The case provides one of the clearest examples of authorities treating prediction-market activity as part of a broader criminal investigation. It also shows why wallet referrals can matter: on-chain records can preserve a visible trading trail even when the public does not know the trader’s identity when the transactions occur.</p><h2 class="wp-block-heading" id="strong-google-linked-case-adds-to-insider-trading-concerns-strong"><strong>Google-linked case adds to insider-trading concerns</strong></h2><p>A separate case involved a Google engineer accused of using unreleased company data to trade on Polymarket. As crypto.news <a href="https://crypto.news/polymarket-trader-accused-of-making-1-2m-using-google-insider-data/" rel="noopener noreferrer nofollow">reported</a> in May, U.S. prosecutors and the CFTC charged Michele Spagnuolo over allegations that he used confidential Google search trend information to place about $2.7 million in prediction-market wagers. Authorities said the trades generated about $1.2 million in profit.</p><p>That case broadened the focus beyond military and government information. It showed that prediction markets can attract traders with access to private corporate data as well as sensitive state information. The allegations also raised questions about how platforms monitor markets whose outcomes depend on information controlled by a small group of employees, officials or contractors.</p><h2 class="wp-block-heading" id="strong-iran-markets-bring-geopolitical-trading-under-closer-review-strong"><strong>Iran markets bring geopolitical trading under closer review</strong></h2><p>Geopolitical markets have drawn some of the strongest scrutiny in 2026. <a href="https://crypto.news/senators-target-death-linked-markets-on-kalshi-polymarket-after-iran/?utm_source=chatgpt.com" rel="noopener noreferrer nofollow"></a>More than <a href="https://crypto.news/senators-target-death-linked-markets-on-kalshi-polymarket-after-iran/" rel="noopener noreferrer nofollow">$529 million traded on Polymarket markets</a> tied to the timing of strikes on Iran, while several newly created wallets drew attention after making profitable positions before major events. Six Democratic senators later urged the CFTC to restrict contracts tied to death, citing national security and public safety concerns.</p><p>The Bloomberg analysis places those earlier cases within a wider pattern. According to the Polysights data, many flagged trades involved markets linked to Iran and Venezuela. Polymarket’s decision to refer nearly 100 wallets shows a more active surveillance approach, although the company has not said that every referred wallet broke the law or used nonpublic information.</p><p>Prediction markets also face wider regulatory pressure. As crypto.news reported on July 19, France <a href="https://crypto.news/france-orders-isps-to-block-polymarket-as-scrutiny-widens/" rel="noopener noreferrer nofollow">ordered</a> internet service providers to block Polymarket after regulators cited unauthorized gambling, weak identity checks and concerns about market integrity. The Czech Republic has also restricted access, while European regulators continue to examine whether some event contracts fall under existing financial rules.</p><p>Lawmakers designed most insider-trading rules around securities markets, while prediction contracts can cover politics, military operations, technology and corporate data. That makes enforcement more complex when traders use information that the public cannot access.&nbsp;</p><p>Polymarket’s referrals give authorities wallet-level data to review, but investigators still need evidence connecting specific trades to unlawful use of confidential or classified information.</p><p>Read more: <a href="https://crypto.news/coinbase-backs-clarity-act-trump-ethics-fight-deepens/" rel="noopener noreferrer nofollow"> Coinbase backs tougher CLARITY Act as Trump ethics fight deepens </a></p>
