Polymarket Paid Creators to Post Fake Betting Videos
TechCrunch reports that The Wall Street Journal investigation found Polymarket paid online creators to post deceptive videos depicting lucrative bets and winnings on its prediction-market site. WSJ analysed roughly 1,100 videos and reviewed instructional materials Polymarket provided to creators; many videos were filmed on near-perfect copies of the Polymarket website and showed trades that were not real. A marketing contractor reportedly amplified those posts with a "social-media army," and creators were discouraged from disclosing payments. Some creators later added partner tags after journalistic inquiries. Razeen Khan, a college student who worked with Polymarket, compared the content to idealised commercials. Polymarket said it will audit its promotional content and stated its commitment to accurate, transparent markets.
Hackers stole funds from Polymarket users
Polymarket, a prediction market platform, confirmed hackers stole users’ funds after a compromise at a third-party vendor allowed malicious code to be injected into its website for some users. Polymarket said it has contained the incident, is contacting affected users and will refund victims in full. Blockchain monitoring firm PeckShield reported a related phishing campaign and estimated about $3 million in cryptocurrency was stolen; a blockchain analyst said losses affected more than 11 victims. Polymarket’s spokesperson confirmed the theft but declined to provide further details. The breach follows separate recent scrutiny of Polymarket over deceptive promotional content, which the company said it would audit.
Polymarket Raises $300M from Donald Trump Jr.'s Fund
Polymarket, a popular decentralized prediction market, has reportedly secured $300 million in funding from 1789 Capital as part of a larger round aiming for $1 billion. 1789 Capital, where Donald Trump Jr. serves as a partner, previously injected $200 million into the platform. This massive capital influx occurs amidst escalating regulatory conflicts. Polymarket and other prediction sites are currently facing lawsuits from at least 20 state governments attempting to regulate sports wagers, while federal authorities, backed by the Trump administration, push for the Commodity Futures Trading Commission (CFTC) to serve as the sole regulator.
