C3.ai CEO Thomas Siebel sold 444,248 shares of Class A Common Stock on September 15 and 16, 2026, at a weighted average price of $10.77 per share, totaling roughly $4.8 million. The sale came shortly after the company's stock dropped 40% over the past year, reflecting broader growth concerns in the AI software sector. His direct holdings stayed unchanged because of a simultaneous option exercise, but he still controls about 8.6 million shares through trusts.
The executive sale is not an isolated event. C3.ai CFO Andrew Ng previously sold 100,000 shares worth $1.2 million in November, signaling that leadership has been taking advantage of weaker valuations. The stock's decline mirrors wider unease about the technology sector and the pace of AI monetization.
Meanwhile, the Trump administration is preparing to showcase America.gov, a new AI tool designed as a one-stop shop for federal government services. The event at the Andrew W. Mellon Auditorium in Washington, D.C., is expected to feature President Donald Trump, Vice President JD Vance, and industry figures such as Elon Musk and Nvidia CEO Jensen Huang. Panel discussions will cover AI, energy, health, space, and agriculture.
On the international front, the United States and China have agreed to hold a super intelligence dialogue by November. The talks will focus on developing AI in ways that benefit both countries, with experts addressing ethics, bias, and explainability. A White House official described the dialogue as more structured than previous efforts, though tensions over AI development remain high.
Secretary of State Marco Rubio cautioned that a proposed US-China emergency warning line for AI incidents is still an early concept. Rubio said the idea may not be ready for signing before Chinese President Xi Jinping's expected US visit and stressed that AI policy needs a global approach.
In other AI-related developments, DraftKings reportedly uses AI-powered player segmentation to identify users likely to lose and then targets them with more marketing, though the company denies the claims. Meta's Muse Charm app is drawing attention because it can monitor personal finances and move money to better deals, potentially compressing bank margins. Pendle also launched the ORBIO token on Robinhood, letting users trade universal AI credits tied to staked ORBIO tokens.
