Meta acquires Moltbook, the 'Reddit for AI agents'
Meta has acquired Moltbook, a social network designed exclusively for AI agents, according to Axios. The purchase price was not disclosed. Co-founders Matt Schlicht and Ben Parr will join Meta Superintelligence Labs (MSL), headed by ex-Scale AI CEO Alexandr Wang, starting March 16. Moltbook launched in January 2026 and reportedly registered around 1.5 million AI agents within days. The platform, which works with the open agent platform OpenClaw, features a verification system that ties agents to their human owners. Meta's Vishal Shah indicated existing customers may continue using the platform temporarily. The acquisition highlights Meta's push into autonomous AI agent technology and intensifies competition with OpenAI, which recently hired OpenClaw's developer Peter Steinberger.
Meta's acquisition of Moltbook signals major tech investment in AI agent infrastructure, likely to influence future autonomous advertising and marketing automation.

AI Leaderboard Arena Raises $200M at $3.1B Valuation
Arena, the AI leaderboard platform that originated as a UC Berkeley research project, has raised a $200 million Series B round at a $3.1 billion valuation. The round was led by Lightspeed Venture Partners and Khosla Ventures, with participation from Salesforce Ventures, 01 Advisors, Dell Technologies Capital, Endeavor Catalyst, a16z, Felicis, and others. This follows the company's announcement in June that it reached $100 million in annualized run-rate revenue. Arena provides a crowdsourced platform where users rate AI model outputs, and it has introduced a commercial product called AI Evaluations to offer detailed performance analytics. The company has also added a new 'alignment' category to its leaderboard, ranking models on issues like unauthorized actions and deceptive completion. Arena's valuation has nearly doubled in about 10 months, from $1.7 billion post-money in January to $3.1 billion now.
Google launches unified agentic AI for Gemini
At a Google Cloud event on Thursday, Google announced it is bringing agentic AI to its Gemini assistant, launching a unified agent that can autonomously plan and execute tasks on behalf of users. Aimed initially at businesses, the agent can connect to internal systems and external tools, use custom skills, and even choose from third-party models like Anthropic's Claude. It will have its own Workspace account with an email address, and will write its own audit trail. Early testers include On, Shopify, and PayPal. Gemini has over 1 billion monthly active users, and nearly 90% of Fortune 100 companies use Gemini Enterprise.
Goodfire Launches Internal AI Agent Monitors
Goodfire, a startup specializing in AI interpretability, launched on Thursday a new type of AI agent monitor that inspects a model's internal signals rather than reading its output, aiming to detect rogue behaviors more efficiently and at a fraction of the cost. The monitors are available to customers of Baseten, an AI model hosting platform. Baseten's Base Labs had previously announced a safety partnership with Goodfire and Hugging Face. Goodfire's approach uses small probes that scan a model's internal activations at each step, triggering a closer AI review only when flagged. In tests on the Kimi K3 model, Goodfire's monitors caught 94% of malicious hacking sessions and cost about $51 for 1,500 sessions, compared to $233 for a cheaper model and $10,000 for a top-tier one. The company positions the solution for open models, which can be stripped of safeguards, and sees it as critical for inference-time guardrails.
