SoftBank Shares Jump 7% After $11.1 Billion Bond Sale to Fund Final OpenAI Payment

CNBC Technology ↗

SoftBank shares jumped more than 7 percent after the Japanese investor issued $11.1 billion in bonds, split between $10 billion in dollar notes and 1 billion euros in euro notes, to fund its OpenAI bet. Proceeds will cover the $10 billion final tranche of the $30 billion follow-on investment SoftBank committed to OpenAI, expected to close October 1. The bond sale brings SoftBank's total OpenAI investment to $64.6 billion once complete. Shares gave back part of the gain later in the session, reflecting investor uncertainty over the economics of Masayoshi Son's OpenAI bet.

Palo Alto Networks CEO Says Slowing Down AI Is Unrealistic, Extinction Threat Extremely Small

CNBC Technology ↗

Palo Alto Networks CEO Nikesh Arora said calls to slow down AI development are unrealistic, arguing that some companies would keep advancing at the frontier regardless of any coordinated pause. He said the odds of AI causing human extinction are extremely small, pushing back on the roughly 10 percent probability some researchers have floated. Arora argued that trying to stop the most capable labs would be counterproductive since they tend to be the most responsible developers. His comments align him with Nvidia CEO Jensen Huang, putting the two executives at odds with more cautious warnings from the CEOs of Anthropic and OpenAI.

Darktrace CEO: AI Agents Are the New Insider Threat

Bloomberg Technology ↗

Darktrace CEO Ed Jennings says AI agents are becoming a new kind of insider threat as companies rapidly deploy autonomous systems with access to sensitive data and infrastructure. As Darktrace launches new tools to track shadow AI, agent identities, and behavior, Jennings discusses why cybersecurity is racing to catch up with adoption and what happens when agents act beyond their intended roles. He argues behavioral monitoring could help companies safely capture the benefits of AI while limiting the risk of agents overstepping their roles. Jennings made the comments in an interview with Bloomberg Television.

Meta Introduces Muse Charm, a Palm-Sized Device for Its AI Agent

Bloomberg Technology ↗

Meta unveiled Muse Charm, a keychain-sized pendant activated by a fingerprint sensor that lets users carry its Muse AI assistant everywhere without a phone. The device is about the size of a small wireless earbuds case, with a roughly 2 inch touchscreen, built-in 5G connectivity, and hardware for voice interaction, and is set to ship during the December holiday period. Meta unveiled it alongside $1,299 VR glasses at its Connect conference as it pushes deeper into AI-powered hardware. The launch follows Muse's rise to the top of the Apple and Android app stores in the US since its September 8 debut.

AI Evaluators Raise Ideological Bias Concerns for Trump, Industry

Bloomberg Technology ↗

Independent groups that evaluate AI models for safety risks have become a flashpoint in the broader political fight over how fast AI should advance, with their assessments now shaping industry practice and financial markets. Evaluators such as METR are drawing growing interest from Anthropic, Meta, and other AI developers as a preferred check on harmful models, and Microsoft has become the latest company to publicly back the approach. Critics, including some aligned with the Trump administration, worry the evaluators could import ideological bias into judgments about which models are safe to release. The debate underscores how model evaluation, once a niche technical function, has become central to AI policy.

Business Insider Tech ↗

The medical AI startup known as the ChatGPT for doctors was valued at $15 billion in a new funding round, after raising nearly $800 million over the past year. Investors in the round included Nvidia, Thrive Capital, Kleiner Perkins, Andreessen Horowitz, and Sequoia Capital. The company gives physicians AI-generated, citation-backed answers to clinical questions and has seen rapid valuation growth since raising its first outside capital last year. The jump reflects continued investor appetite for AI applications in healthcare despite broader questions about inflated AI valuations.

Google Tests Letting Gemini Call Businesses for You

TechCrunch AI ↗

Google is testing a new Gemini feature called Call for Me that lets the AI phone businesses on a user's behalf to check product availability, book reservations, reschedule appointments, or place items on hold. The beta requires Pixel 11 owners in the US who subscribe to Gemini and the beta version of Google's Phone app, and callers can watch a live transcript or take over the call at any time. The rollout comes as rival AI agents including Meta's Muse and Instinct also gain the ability to make phone calls on users' behalf. Google said years of experimentation were needed because real-world conversations are nuanced.

ElevenLabs CEO Talks $22 Billion Valuation, Margins, and AI Disclosure Ahead of IPO

TechCrunch AI ↗

The AI voice startup is reportedly valued at $22 billion and pacing toward $600 million in annual recurring revenue, more than half of it from enterprise customers. CEO Mati Staniszewski declined to share gross margin figures but said the company is willing to let profits compress if it expands its reach, adding that efficient model fine-tuning helps offset costs. He avoided committing to a specific IPO date, saying the company is laying the groundwork to go public in the next few years depending on market conditions. Staniszewski also said businesses should currently disclose when customers are talking to an AI voice agent, though he expects that norm to fade within five years as the technology becomes ubiquitous.

PrismML Brings Its Tiny LLMs to Qualcomm-Powered Smart Glasses

TechCrunch AI ↗

The Caltech-founded startup unveiled a 1-bit language model called Bonsai, tuned for Qualcomm's Snapdragon AR1 Gen 1 platform used in smart glasses. The 2 billion parameter model runs locally on-device, letting wearers ask what they are looking at in real time using both vision and language. It compresses larger models roughly 4 times over while preserving performance, aiming to offer open-weight AI that runs on-device as an alternative to cloud-dependent assistants. No smart glasses product using the technology has been announced yet.

Island reported roughly $200 million in annual revenue as of September 2026, growing about 100 percent per year. It plans to use the new funding to expand from securing browsers into a broader control layer for the AI agents operating inside companies.
