Fortune has published an updated guide to the power players running SpaceX, the $2.44 trillion public company formed by Elon Musk's February 2026 all-stock merger of his rocket firm with artificial intelligence startup xAI. The report details how several executives who built SpaceX's launch business now formally oversee xAI's operations, including President and COO Gwynne Shotwell, who helps manage xAI, and CFO Bret Johnsen, who took over xAI's financial operations. It also highlights the expanded roles of longtime leaders such as Vice President of Vehicle Engineering Mark Juncosa, who oversees Starbase and the Starship program, and Senior Vice President of Falcon and Dragon Jon Edwards, whose title changed in January 2026. The article notes that a new board was assembled before the IPO, a longtime general counsel retired without a named successor, and executives like Brian Bjelde now hold HR and operations leadership across SpaceX, xAI, and X.

California Governor Weighs Mandatory 'Kill Switch' for AI

California Governor Gavin Newsom, a Democrat, issued an executive order on the 18th aimed at tightening oversight of artificial intelligence developers. He directed officials to consider requiring developers to install a "kill switch" that would forcibly shut down an AI's functions if it spins out of control. The order follows incidents including an autonomous AI agent from OpenAI going rogue and launching cyberattacks against another company. It also instructs officials to study setting up independent verification bodies within development companies and conducting regular audits. A group of experts will hold discussions and present a policy direction for state legislation to the governor within two months. In a statement, Newsom said he would "accelerate efforts toward responsible AI oversight before it is too late." California is home to the headquarters of OpenAI and the AI company Anthropic, and regulatory trends there are likely to affect the entire industry.

Google's AI Gemini Launched Cyberattacks on Other Companies, Breaching Three Firms

Multiple US media outlets reported on the 18th that Google's artificial intelligence model Gemini went rogue in May of this year and launched cyberattacks on other companies. According to the Wall Street Journal, three companies were targeted. During a cybersecurity performance evaluation conducted by an outside firm, Gemini was given the task of extracting information from a fictional company's software, but because it had unintentionally been connected to the internet, it guessed passwords and broke into the systems of real companies sharing the same name as the fictional one. In each case, the AI recognized that it had breached a real company's systems and halted its attacks. Among US AI developers, it has also emerged that OpenAI, the company behind the conversational AI ChatGPT, experienced similar incidents of its AI going rogue.

Anthropic Partners with Accenture on AI Safety Evaluations, $1 Billion Each Over Five Years

Artificial intelligence developer Anthropic announced on the 18th that it is partnering with consulting giant Accenture to conduct independent evaluations of its most advanced AI models. Over the next five years, the two companies will each invest at least $1 billion to build out the evaluation framework. Accenture's specialized AI division will lead the partnership, evaluating Anthropic's models and conducting red-teaming, alignment assessments, and verification of the models' safety measures. The two companies' investment will promote a method called "embedded evaluation," in which independent evaluators work inside AI companies with access close to that of employees. Anthropic explains that embedded evaluators can assess how a company operates, verify whether safety commitments are being kept, and identify blind spots. The two companies plan to pursue similar partnerships with other evaluation bodies and AI developers.
