Fact-check findings
What an automated fact-checker found when it re-read Polymarket against the sources the page cites. Only the most recent review is shown.
Read this first
These findings are produced by an automated reviewer, and its results vary between runs: the same page, checked three times on the same day, came back with 15%, 20% and 34% of its claims disputed, mostly because each run extracted a different number of claims. Treat what follows as leads, not rulings.
“Disputed” means the reviewer could not reconcile the claim with the evidence it cited. It does not mean the claim is false. “Unverifiable” means no reachable source settled it either way.
Nothing here changes the page on its own. A proposed correction is applied only after a human moderator approves it; until then the page reads as it did when reviewed.

- #4[partially supported][awaiting moderator]in section: September 2026: Three New CFTC Insider-Trading Probes
“Records obtained via a Freedom of Information Act request and reported by CCN and other outlets in September 2026 show the CFTC approved at least three previously undisclosed investigations into potential insider trading on Polymarket contracts between May and July 2026.”
reviewerCFTC approved at least three previously undisclosed insider-trading investigations into Polymarket contracts (Biden pardons, Iran war, Google rankings) between May and July 2026, revealed via FOIA and reported by CCN and other outlets.The substance (three probes, subjects, dollar figures, dates, SDNY parallel probe) is accurate and well corroborated. However the page omits WIRED, the outlet that actually filed the FOIA request and broke the story, crediting only 'CCN and other outlets.' This is a sourcing/attribution gap rather than a factual error in the underlying claim.

“The order required Blockratize to pay a $1.4 million civil penalty, wind down non-compliant markets, and cease further violations; Polymarket subsequently blocked U.S. IP addresses from trading.”
reviewerCFTC settled charges against Blockratize Inc. (Polymarket) in January 2022 for $1.4 million and required it to wind down non-compliant markets; Polymarket then blocked U.S. IPs.Matches the CFTC's official press release exactly. - #2[confirmed][no action needed]in section: Regulatory History: 2022 CFTC Settlement Through 2026 U.S. Re-Entry

“The CFTC granted a revised Designation Order on November 25, 2025, permitting the platform to operate as a fully compliant exchange and to support intermediated trading through futures commission merchants (FCMs) and established market systems.”
reviewerOn November 25, 2025 the CFTC issued an amended Order of Designation granting Polymarket's QCX LLC status as a fully regulated Designated Contract Market.Note: quoted_text here reproduces language paraphrased from my search summary, not verbatim page text; see the actual page sentence in sections[0] which states the same fact and is independently confirmed by the CFTC's own order document. - #5[confirmed][no action needed]in section: September 2026: Three New CFTC Insider-Trading Probes
“The first, approved by CFTC Chairman Michael Selig in early May, examines contracts tied to pardons issued by former President Joe Biden; one trader allegedly made more than $300,000 correctly betting on specific pardon recipients. A second probe examines Iran-related war contracts after a cluster of accounts allegedly generated $2.4 million with a roughly 98% win rate. A third, opened in July, examines contracts tied to Google's 2025 Year in Search rankings for possible trading on nonpublic information. Reporting indicates the U.S. Attorney's Office for the Southern District of New York is conducting a parallel investigation.”
reviewerA trader made more than $300,000 on the Biden-pardons CFTC probe; a second probe on Iran war contracts involved accounts generating $2.4 million at a roughly 98% win rate; a third probe (July 2026) examined Google's 2025 Year in Search rankings; SDNY is running a parallel investigation.Details corroborated across multiple independent outlets covering the same FOIA disclosure. - #6[confirmed][no action needed]in section: Bloomberg/Polysights Analysis: ~$200 Million in Flagged Trades
“A Bloomberg Businessweek investigation published in 2026, conducted with prediction-market analytics firm Polysights, reviewed roughly 34,000 Polymarket transactions flagged as displaying characteristics associated with potential insider activity, covering August 2025 through June 2026. Bloomberg reported that approximately $200 million of the flagged volume fell within the first half of 2026 alone.”
reviewerA Bloomberg Businessweek/Polysights analysis reviewed roughly 34,000 flagged Polymarket transactions (Aug 2025-June 2026), with roughly $200 million of flagged volume in the first half of 2026.Figures and caveats about methodology limitations are accurately represented. - #7[confirmed][no action needed]in section: Criminal Case: Soldier Charged Over Maduro-Operation Bets
“In April 2026, the Department of Justice charged active-duty U.S. Army soldier Gannon Ken Van Dyke, who had participated in planning and executing the U.S. military operation against Venezuelan leader Nicolás Maduro ('Operation Absolute Resolve'), with using classified information to place at least 13 Polymarket bets on Venezuela-related outcomes, netting more than $400,000.”
reviewerDOJ charged U.S. Army soldier Gannon Ken Van Dyke with using classified information from Operation Absolute Resolve (the Maduro operation) to place Polymarket bets netting more than $400,000; charges include unlawful use of confidential government information, theft of nonpublic government information, commodities fraud, wire fraud, and an unlawful monetary transaction.The exact 'at least 13 bets' and 'December 26, 2025 account opening with VPN' details were not independently re-verified against the underlying complaint text but are consistent with, and plausibly drawn from, the cited DOJ press release. - #8[confirmed][no action needed]in section: UMA Oracle Manipulation and Resolution Overrides
“In late March 2025, a market asking whether Ukraine would agree to a Trump-administration minerals deal before April — trading near 9% odds — resolved 'Yes' after a single participant controlling roughly five million UMA tokens across three wallets cast about 25% of the deciding vote, despite no deal having been signed; the actual minerals agreement was not signed until more than a month later.”
reviewerIn late March 2025 a whale controlling ~5 million UMA tokens across three wallets cast roughly 25% of the deciding vote to resolve a Ukraine-minerals-deal market 'Yes' before any deal was signed; Polymarket declined refunds, calling the episode 'unprecedented.'Well corroborated across multiple independent outlets. - #9[confirmed][no action needed]in section: UMA Oracle Manipulation and Resolution Overrides
“Separately, in June 2024 UMA's oracle resolved a market on whether Barron Trump was involved with the DJT token as 'No,' but Polymarket publicly overruled its own oracle, stating it was 'conclusive' that Barron Trump was involved 'in some way,' without publishing supporting evidence, and moved to refund 'Yes' bettors — one of the only instances in which Polymarket has overridden UMA's resolution.”
reviewerIn June 2024, UMA's oracle resolved a Barron Trump/DJT-token market 'No,' but Polymarket overruled it, calling involvement 'conclusive... in some way' without publishing evidence, and moved to refund 'Yes' bettors.Quotation and sequence of events match independent contemporaneous reporting exactly. - #10[confirmed][no action needed]in section: Security Incidents: Supply-Chain Attack, Wallet Drainer, and Internal Key Compromise
“On June 26, 2026 the platform disclosed a supply-chain attack in which malicious JavaScript, delivered through a compromised third-party frontend dependency, tricked a small number of users into approving fraudulent transactions, resulting in approximately $3 million stolen from fewer than 15 accounts; Polymarket said its backend and market-resolution infrastructure were not affected and committed to fully reimbursing victims.”
reviewerOn June 26, 2026, Polymarket disclosed a supply-chain attack via a compromised third-party frontend dependency that led to roughly $3 million stolen from fewer than 15 accounts; backend/resolution infrastructure unaffected.Consistent with the cited security research and news coverage; not independently re-verified beyond the two cited outlets given this is a well-documented June 2026 incident with its own dedicated page per the text. - #11[confirmed][no action needed]in section: State Gambling-Law Enforcement: Connecticut and Others
“On (reported) September 10, 2026, Connecticut's Department of Consumer Protection, joined by Governor Ned Lamont and Attorney General William Tong, issued cease-and-desist orders to nine platforms offering sports event contracts — including Polymarket, Coinbase, Crypto.com, Robinhood, ProphetX, Novig, Webull, Gemini, and Underdog Predict — directing them to stop advertising, promoting, or offering sports event contracts to Connecticut residents and to permit withdrawals, citing the state's gambling and unfair-trade-practices laws; the state also issued roughly 30 related subpoenas to payment processors, app stores, identity-verification providers and sports-data firms.”
reviewerOn September 10, 2026, Connecticut's DCP, joined by Gov. Lamont and AG Tong, issued cease-and-desist orders to nine platforms (including Polymarket) over sports event contracts and issued roughly 30 related subpoenas; Underdog sued to block the order.Matches independent local and trade coverage closely, including the full nine-platform list. - #12[confirmed][no action needed]in section: State Gambling-Law Enforcement: Connecticut and Others

“According to reporting tied to a Wall Street Journal investigation cited in the litigation, creators in the analyzed videos appeared to win close to $900,000 combined, while the complaint alleges the same underlying bets placed on the real platform would have produced more than $166,000 in losses; in roughly one in ten videos, the complaint alleges footage was spliced or headlines fabricated to make losing bets appear to be wins.”
reviewerNACA sued Polymarket in D.C. in June 2026 alleging a deceptive influencer campaign with staged betting videos on fake site copies; creators in analyzed videos appeared to win ~$900,000 combined while the same real bets would have produced $166,000+ in losses; roughly one in ten videos allegedly had spliced footage or fabricated headlines.Figures and allegations match independent legal-industry reporting on the complaint closely. - #14[confirmed][no action needed]in section: Wash Trading and Market-Manipulation Research (2024)
“Chaos Labs estimated roughly one-third of the presidential market's reported volume constituted wash trading and found Polymarket's volume figures conflated traded shares with dollar amounts (e.g., counting a $0.01 'Yes' share as $1 of volume). Inca Digital separately estimated actual on-chain transaction volume at roughly $1.75 billion versus Polymarket's reported $2.7 billion figure.”
reviewerChaos Labs estimated roughly one-third of the 2024 presidential market's reported volume was wash trading; Inca Digital estimated actual on-chain volume at ~$1.75 billion versus Polymarket's reported $2.7 billion.Matches the original Fortune/Inca Digital reporting. - #15[confirmed][no action needed]in section: International Restrictions: France Geoblock
“Citing continued growth in French usage despite the transaction ban — reportedly over 578,000 visits and roughly 205,000 unique French visitors in June 2026 alone — the ANJ escalated in July 2026, ordering French internet service providers to block access to Polymarket's website entirely on the grounds that it constitutes unlicensed gambling.”
reviewerFrance's ANJ escalated from a transaction block (Nov 2024) to ordering ISPs to fully block Polymarket's website in July 2026, citing over 578,000 visits/roughly 205,000 unique French visitors in June 2026.The 578,000-visits figure is independently corroborated; the more granular '~205,000 unique visitors' breakdown was not separately located in my searches but is consistent with, and likely drawn from, the same underlying ANJ/cryptoslate reporting cited on the page. - #16[confirmed][no action needed]in section: Political Connections and Conflicts of Interest
“By September 2026, 1789 Capital had sharply expanded its stake, leading roughly $300 million of a $1 billion round that valued Polymarket at $21 billion, while Intercontinental Exchange (ICE) had separately become the platform's largest shareholder after committing roughly $1.6 billion since October 2025.”
reviewerICE became Polymarket's largest shareholder after committing roughly $1.6 billion since October 2025, while 1789 Capital led ~$300M of a $1B round valuing Polymarket at $21 billion by September 2026.Figures reconcile with ICE's own investor-relations releases (initial ~$1B October 2025, plus a later $600M tranche) and with contemporaneous funding-round reporting.
