Meta Platforms shares rose 1.5% to $748.11 after early traction for its new Muse artificial intelligence agent continued to drive market optimism ahead of the Meta Connect conference on September 23–24. Wells Fargo analyst Ken Gawrelski kept an Overweight rating and raised his price target to $796 from $640, saying recent model launches and early Muse traction give Meta a story to tell at Connect. Citing SensorTower, the firm said U.S. Muse downloads hit a record 264,000 on September 19 and daily active users reached 448,000 on September 18. Meta launched Muse in the U.S. on September 8 as a personal AI agent that can send email, book travel, fill out forms, and keep working after the app closes, running on the Muse Spark model and available on iOS, Android, muse.ai, and WhatsApp. Barron's reported that OpenAI's GPT-6 Sol and Luna and Anthropic's Claude Opus 5.5 were relatively low-cost models that were still overshadowed by Muse, and that Anthropic is unlikely to launch a Muse competitor because it sells mainly to businesses. Meta is up 15% since the beginning of the year and is trading close to its 52-week high of $760.66 from September 2025.
Anthropic's Claude Opus 5.5 is cited as overshadowed by Muse, and it is said unlikely to launch a Muse competitor.

42 State AGs Build AI Agent Liability Framework as Congress Stalls
A bipartisan coalition of 42 state attorneys general is building the liability framework for agentic AI that Congress has yet to codify, filling a federal regulatory void confirmed by the Congressional Research Service. In December 2025, the coalition, led by officials from Pennsylvania, New Jersey, West Virginia, and Massachusetts, issued a coordinated letter to 13 major AI companies including Anthropic, Apple, Google, Meta, Microsoft, OpenAI, and xAI, demanding chatbot safeguards with a response deadline of January 16, 2026. State AGs are repurposing existing UDAP statutes, consumer protection laws, civil rights frameworks, and antitrust authority to police AI behavior, an approach that produced a first-of-its-kind settlement by Texas Attorney General Ken Paxton with healthcare AI company Pieces Technologies over false accuracy claims. Connecticut's AI Responsibility Act, signed in May 2026, grants the state AG exclusive enforcement authority under CUTPA starting October 1, 2026, with a mandatory one-year cure period through September 2027, while New Jersey's Fair Price Protection Act, effective August 2027, allows a private right of action for surveillance pricing with treble damages and no cure period. The Pennsylvania AG has sought preliminary injunctions against an AI company for falsely representing a chatbot as a licensed psychiatrist, and the Florida AG launched a criminal investigation in April 2026 after a violent incident involving a chatbot. State AGs filed seven antitrust actions in 2026 alone, surpassing the prior two years combined, including a 30-state coalition continuing the monopolization case against Live Nation and twelve states suing to block the Paramount-WBD merger despite federal declination.
Meta's Muse Chatbot Sparks AI Narrative Shift, Fastest App Store Adoption Since ChatGPT
Meta Platforms' Muse chatbot has driven AI stocks higher this week and may have triggered a broader tonal shift in the AI narrative and how consumers use the technology. Futurum CEO Daniel Newman said the new Muse agentic platform is "taking over the internet," with the fastest adoption in the App Store since ChatGPT. Newman noted that Meta's Muse Spark model, the new model released first, tested and benchmarked on pinnacle very close to leading edge models from OpenAI and Anthropic. He said the launch followed a period in which investors questioned Meta's exploding CAPEX and its Reality Labs investments, and after Meta went all in on its super intelligence lab with elite hires costing hundreds of millions and billions on individual talent. Newman added that Muse arrived "out of nowhere" after a week of AI doomerism, and that bringing AI to consumers this way was needed to get the next leg up of optimism on the AI trade.
Palo Alto Networks launched a worldwide annual subscription that puts Unit 42's security testing on a continuous cycle, sending shares up about 3.45% to $387.485 Wednesday morning. The service draws on Anthropic's Claude Mythos 5, OpenAI's GPT-5.6-Cyber and open-weight models, and Palo Alto says it can test applications, APIs, cloud systems, code and networks, then prioritize fixes and recommend virtual patches. The company frames the distinction as whether those tests lead to fewer openings for attackers rather than a longer list of alerts. At $387.485, the shares stood 66.17% above the $233.18 GF Value shown for September 23. Annual contracts could make Unit 42's revenue steadier, but model usage and specialist work carry costs, and renewals, customer results and margins will show whether the launch earns its place in the valuation.
