Summary · why it matters

HiddenLayer, an Austin-based startup, has raised $100 million in Series B funding to formalize a new standalone category of AI agent security, signaling a shift in enterprise protection as autonomous agents become core to operations. The round, announced on September 2, 2026, was led by Delta-v Capital with participation from Ten Eleven Ventures, Morgan Stanley, M12, and Booz Allen Ventures. This investment is part of a broader surge: over the past five weeks, more than $150 million has flowed into the niche, including a $50 million raise by AIR. HiddenLayer CEO Chris Sestito said the funding will help the company "keep growing the purpose-built team and platform required to meet that moment as agentic AI becomes core to how enterprises operate." The category encompasses Agentic Runtime Security and Agent Harness Security, addressing the need to monitor agents during operation and secure their environments. Industry moves like Broadcom's AgentMinder and Okta's Agent SSO underscore the trend toward treating agents as first-class citizens requiring dedicated protection.

A $5,000 investment in Palantir Technologies could be worth between $4,629 and $8,161.50 by 2031 under a five-year scenario model built on current data. The base case projects shares at $217.44 for a 23.62% total return and a stake of about $6,181, the bull case targets $287.10 for a 63.23% return and $8,161.50, and the bear case puts the stock at $162.84 for a 7.42% loss and $4,629. Palantir posted second-quarter 2026 revenue of $1.935 billion, up 92.83% year-over-year, with a Rule of 40 score of 155 and adjusted free cash flow of $1.22 billion at a 63% margin, and management raised full-year 2026 revenue guidance to $8.150 to $8.158 billion. Total remaining deal value reached $13.1 billion, up 83%, net dollar retention expanded to 157%, and CEO Alex Karp said demand for AI sovereignty has been unleashed. The stock trades near $175.91 at a P/E of roughly 250 and a beta of 1.621, and the model carries a 0.9 confidence score with a hold recommendation.

Digital Realty Launches ServiceFabric MCP Across 800 Data Centers

Digital Realty made ServiceFabric MCP available on September 15, a software layer that lets AI agents design, monitor and troubleshoot network connections across more than 800 data centers, including third-party sites. The launch follows second quarter results reported on July 23, when Core FFO per share, excluding net promote, rose to $2.13 from $1.87 a year earlier, while the headline figure of $2.65 included a $188 million net promote. Renewal leases in the quarter were signed at rates 25.4% higher on a cash basis, and signed leases waiting to start added up to a $1.9 billion backlog of annualized base rent at 100% share. Management lifted its 2026 Core FFO per share outlook, excluding net promote, to $8.15 to $8.20, even as the company carried about $18.6 billion of debt at June 30, 2026 and set its 2026 development spending outlook, net of partner contributions, at $4.25 billion to $4.75 billion. Digital Realty calls MCP an emerging standard still being validated, and the announcement puts no dollar figure on what it could add to revenue.

Meta Acquires AI Startup Stilla.ai to Bolster Business Agent

Meta Platforms acquired AI startup Stilla.ai on September 9, a move aimed at strengthening its agentic AI capabilities and opening new monetization beyond advertising. The company plans to integrate Stilla.ai's team and technology into Meta Business Agent, which helps businesses interact with customers across its platforms. Longer term, Meta envisions customers using AI agents to inquire about products, discuss pricing, and potentially complete purchases without leaving its ecosystem, creating an AI-driven commerce layer across Facebook, Instagram, Messenger, and WhatsApp. Meta cautioned that Stilla.ai remains a small startup and the deal is unlikely to materially affect revenue or earnings per share in the near term, with infrastructure, product development, and integration needed before meaningful transaction-related revenue emerges. According to the Insider Monkey Database, 254 hedge funds held positions in Meta during the second quarter, down from 262 at the end of the first quarter, while short interest stood at approximately 1.13% of outstanding shares, or roughly 28.81 million shares, as of August 31.
