Few companies already have explicit policies; many are still developing guidance, while experts urge proactive training, monitoring, and clearer rules—especially as exchanges expand oversight and regulators explore liability for corporate employees.

Polymarket Putin Exit Bet Sparks Buzz, But No Proof Yet

A large Polymarket bet (~$409,000) that Vladimir Putin will leave office by December 31, 2026 has drawn attention to prediction-market activity, but NBC News notes there’s no evidence of an imminent ouster amid the ongoing Ukraine conflict. The piece also highlights ongoing concerns about insider trading on such platforms and references a separate DOJ case involving bets tied to Venezuela. In short, a big wager doesn’t guarantee Putin’s departure, though it underscores speculative interest around his presidency.

Young men chase fast money in prediction markets

CBS News reports that prediction markets like Kalshi and Polymarket attract many young men seeking quick profits and the thrill of risk. About 40% of 18–34-year-olds use these markets, and men comprise the vast majority of users (roughly 3 million of Kalshi’s 4 million). Traders wager on yes/no events and even “mention markets” for phrases spoken by public figures; some wins are sizeable, but most users lose money, with a median ROI around -8% and a small share capturing most profits (0.1% on Polymarket). Personal stories show big early wins followed by losses, reflecting high risk tolerance and the appeal of social status from success, while insider-trading scrutiny remains a concern. Experts note this activity may appeal to financially anxious individuals who overestimate their odds.

Former BigLaw attorney denies insider-trading charges in Boston case

Nicolo Nourafchan, a former mergers-and-acquisitions attorney who worked at Sidley Austin, Latham & Watkins, and Goodwin Procter, pleaded not guilty in a Boston federal court to leading a decade-long insider-trading scheme prosecutors say netted tens of millions by siphoning confidential information on roughly 30 deals and passing tips to traders and go-betweens. He’s joined by 14 other charged defendants, including his brother Lorenzo Nourafchan and co‑conspirator Robert Yadgarov; several others have pleaded guilty. Prosecutors say participants used disposable phones, encrypted messaging, face‑to‑face meetings, and coded language (e.g., before Amazon’s 2022 iRobot deal). The SEC has a parallel civil suit against 21 defendants. A conviction on the gravest counts carries up to 25 years in prison.
