LATEST DEVELOPMENTS
Anthropic began its IPO roadshow, pricing shares at $70–$78 to raise up to $64.4B. The Claude maker could be valued at up to $1.4 trillion, below the $2T once floated.
Details
The offer: Anthropic and some existing shareholders plan to sell 825 million shares at $70 to $78 each. At the top price, that brings in up to $64.4 billion.
Two valuations: Counting stock options and restricted stock, the top price puts Anthropic at about $1.4 trillion. Without them, it is about $1 trillion.
Lower than expected: Earlier estimates ran from $1.5 trillion to $2 trillion. Worries over heavy infrastructure spending and shaky AI stocks pulled the number down.
Big tech buys in: A separate $26 billion private placement is backed by Google, Nvidia, Microsoft and AMD, among others.
Fast growth: Run-rate revenue stood near $81 billion on October 31, a $10 billion jump in one month. Its last private round valued it at $965 billion.
What’s next: Shares are set to trade on the Nasdaq as “ANT”. The roadshow started Tuesday, and the listing is reportedly planned for next week.
Takeaway: Anthropic is asking for less than the hype suggested, which leaves room for investors to bid the price up. The debut will be a real test of how much Wall Street still believes in the AI boom.
Google released Gemini 4 Carbon, its strongest AI model yet, built for hard coding, research and cybersecurity work. It is open to paid developers, businesses and AI Ultra subscribers.
Details
The launch: Google announced Gemini 4 Carbon on November 10, two weeks after giving it to cybersecurity defenders first. Google calls it its strongest model for cybersecurity, long agent tasks, software engineering and scientific reasoning.
Carbon vs Argon: Google says Gemini 4 Argon is still the better pick for most coding and knowledge work. Carbon is for harder jobs like complex debugging and open-ended research, and it uses more tokens to reason and check its work.
Benchmarks: Carbon ranks #1 on CursorBench 4.0, Perplexity’s WANDR and Zapier’s AutomationBench, at more than 2x lower cost per task than the next best outside model. Some of the other results come from internal or pre-release tests.
New /swarm feature: In preview inside Google Antigravity, it turns one prompt into a coordinated team of agents. Carbon takes the heavy thinking roles while lighter models handle the parallel work.
Who gets it: Developers on the paid Gemini API tier, businesses through Gemini for business, and Google AI Ultra subscribers in the Gemini app, Antigravity and AI Mode in Search. Its full cyber abilities stay gated behind the Fairwind Program.
Pricing: $2 input / $10 output per million tokens until November 30, the same as Argon. After that it doubles to $4 / $20.
Safety: In Google’s simulated attack tests, Carbon blocked 99% of attack paths. Google admits its defenses against sophisticated prompt injection can still improve.
Takeaway: Google now has a two-model lineup: Argon for everyday work and Carbon for the hardest problems. The low launch price is a clear push to win developers before it doubles on November 30.
eBay appears to have blocked third-party AI agents, including Meta’s Muse, from browsing its listings. eBay has not confirmed a new crackdown, but it is building its own gateway for approved agents.
Details
What happened: A Verge reader had used Meta’s Muse for weeks to build a daily digest of watches for sale on eBay. Last weekend, Muse said it was blocked from the site and could no longer pull links or details.
The workaround problem: The Verge recreated the issue with other searches. In some cases, Muse sent users to outside sites that mirrored eBay listings instead.
eBay’s response: A spokesperson declined to say whether new limits were added. eBay points to concerns about unauthorized data scraping and being careful about who gets access.
Earlier rules: eBay had already banned “buy-for-me” agents and LLM-driven bots from placing orders without human review. Until recently, though, agents could still browse listings.
eBay’s own plan: The company is building an Agentic Gateway, a controlled entry point for selected outside agents. It has also launched its own Shopping Agent to 3% of US app users.
Wider trend: Amazon has also blocked Muse from its platform, while Walmart lets approved agents buy through its own gateway.
Takeaway: Big retailers want to control how AI shops on their sites, not hand that power to outside agents. If the blocks keep spreading, AI shopping agents will only be as useful as the stores allow.
