MCP Is Becoming the USB-C Cable of the AI World
The article profiles the Model Context Protocol (MCP), which Anthropic introduced in November 2024 as an open standard for connecting large language models to external data sources and tools. MCP is often compared to a USB-C port for AI applications. The piece highlights broad adoption by companies including Block, Apollo, Zed, Replit, Windsurf, Microsoft, OpenAI, Amazon, and Google. Vienna-based AI startup newsrooms.ai uses MCP to link AI assistants to social platforms, CMS, and newsletter systems. Developer enthusiasm is reflected in Sublayer CEO Scott Werner calling MCP a 'universal plugin system.' The article also covers security warnings from Docker's Ajeet Singh Raina, who flagged issues with OAuth, command injection, code execution, and unlimited network access. Figma's Director of Engineering Emil Sjölander says MCP provides AI models with access to the 'private internet,' enabling design and development tools such as Figma and Cursor to work together.
MCP is emerging as a standard integration layer for AI agents and tools across major tech companies, which could shape agentic media workflows and AI-driven advertising infrastructure, though the article does not announce a direct AdTech product or deal.

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.
OpenAI's revenue reportedly $20B less than projected
OpenAI has reportedly informed investors that its annualized revenue is approaching $50 billion, a figure $20 billion lower than the previously reported $70 billion. The earlier figure was based on attempts by OpenAI's own investors to compare with Anthropic's run rate. Discrepancies arise from differing calculation methods; Anthropic includes sales made by cloud partners, while OpenAI does not. OpenAI has raised substantial capital, including $122 billion in a March 2026 funding round, but its leaked 2025 financials showed revenues of $13 billion with significant spending. The company's IPO has been postponed to early 2027.
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.
