OpenAI Fires Employee for Insider Trading on Prediction Markets
OpenAI has fired an employee after alleging the worker used confidential OpenAI information to place trades on prediction markets such as Polymarket. The company told Wired the activity violated its policy prohibiting employees from using inside information for personal gain. The article notes prediction markets, including Polymarket and the regulated exchange Kalshi, allow wagers on real-world events and have markets about OpenAI product announcements and potential IPO timing. Kalshi recently fined and banned an editor associated with MrBeast for a separate alleged insider trading incident. OpenAI did not name the employee, and a company spokesperson emphasized the breach of internal policy. The story highlights enforcement actions and the scrutiny of prediction-market activity tied to corporate insiders.
Kalshi's DC Ad Push Amid Prediction-Market Regulation
CNBC's Morning Squawk highlights market moves and a Washington push by prediction-market operator Kalshi. Kalshi opened a Washington, D.C. office in January and has launched a local billboard campaign emphasizing its ban on insider trading and compliance with U.S. law, part of an effort to differentiate from rival Polymarket as members of Congress introduce at least eight bills to regulate prediction markets. The newsletter also notes Bank of America and Morgan Stanley beat expectations in early earnings, Broadcom and Meta expanded a partnership tied to Meta's custom AI chips, and reports that United Airlines CEO pitched a potential merger with American Airlines earlier this year. CNBC discloses it holds a minority investment in Kalshi.
Bipartisan Bill Targets Sports Betting on Kalshi, Polymarket
Senators Adam Schiff (D‑CA) and John Curtis (R‑UT) introduced bipartisan legislation that would bar prediction‑market platforms Kalshi and Polymarket from permitting wagers on sports events or casino‑style games. The bill excludes state‑regulated sportsbooks such as FanDuel and DraftKings. Schiff and Curtis argue prediction contracts function as sports bets despite being federally regulated by the Commodity Futures Trading Commission (CFTC). Kalshi recently reported dramatic growth — its Super Bowl trading volume topped $1 billion (a ~2700% year‑over‑year increase) — and the company faces recent legal issues including a temporary ban in Nevada and criminal charges in Arizona. Both Kalshi and Polymarket announced new screening and rule changes to limit insider trading and manipulation; Kalshi warned the bill could push users to offshore markets.
