United Bars AI Agents as Anthropic Files for IPO and CSU Builds Bots

Enterprise boundaries around autonomous software agents, public-market valuations for frontier model developers, and bio-inspired mechanical hardware converged this week across three major technology disclosures. While United Airlines moved to block third-party artificial intelligence assistants from executing passenger ticket purchases, San Francisco model developer Anthropic updated its initial public offering paperwork with a target valuation between $1.26 trillion and $1.4 trillion, and mechanical engineers at Colorado State University demonstrated modular shape-shifting robots modeled on elephant trunks.

According to reporting by The Verge, United Airlines updated its customer contract to prohibit passengers from using personal AI assistants—such as Meta's Muse and OpenAI's Dots—to complete flight bookings on its website or mobile app. The carrier stated that bookings submitted through unauthorized automated agents may be canceled without refunds, citing privacy risks when passengers hand login credentials and payment cards to third-party systems as well as federal regulatory requirements, such as personally attesting that checked luggage does not contain explosives. Speaking at an industry event on Tuesday, United CEO Scott Kirby added a commercial rationale for blocking automated intermediaries: "To be honest, I don't want to create another middleman." The restriction mirrors similar guardrails introduced by eBay and several major banks, even as travel platforms like Expedia and Booking.com build internal AI booking tools.

In the capital markets, the San Francisco Examiner reported that Anthropic and CEO Dario Amodei updated their IPO filing on Tuesday to offer at least 825 million shares priced between $70 and $78 each. Across roughly 18 billion outstanding shares, the pricing range values the Claude developer between $1.26 trillion and $1.4 trillion, which would make Anthropic the 13th most valuable publicly traded company globally while sitting up to 37% below a $2 trillion valuation floated over the summer and below a $1.5 trillion target discussed last month. Combined with $26 billion in separate concurrent stock purchases by existing backers Google and Nvidia, the offering remains on track to surpass SpaceX's record $75 billion public listing earlier this year. Anthropic's filing detailed quarterly revenue growth of 132% in Q1, 144% in Q2, and 46% in Q3 alongside more than $900 billion in future infrastructure commitments, drawing analysis from University of Florida professor Jay Ritter, Morningstar analyst Malik Ahmed Khan, Renaissance Capital strategist Avery Marquez, Synovus portfolio manager Dan Morgan, and Wharton professor David Hsu.

Meanwhile, in physical robotics, The Press reported that Colorado State University Department of Mechanical Engineering associate professor Jianguo Zhao and Ph.D. co-first authors Mahmud Hasan Saikot and Sydney Spiegel published a new study in Nature Machine Intelligence detailing modular shape-shifting robots inspired by elephant trunks. Using a "tensegrity" architecture of stiff rods held together by tensioned cables that contract via small motors, each lightweight module features dual gripping claws at both ends rather than heavy magnets. Individual units can crawl and grasp objects independently or link together into longer snake-like assemblies and multi-legged walkers capable of climbing obstacles, crossing gaps, and assembling structures for space exploration, search and rescue, and manufacturing.
