OpenAI completed the largest private funding round in history, raising $122 billion at a valuation of $852 billion. Three major investors led the round: Amazon ($50B, with $35B tied to IPO or AGI achievement), NVIDIA ($30B), and SoftBank ($30B). The company also raised $3B through banking channels for individual investors and was added to multiple ARK Invest ETFs.

OpenAI reports monthly revenue of $2B, with $13.1B revenue in 2025, 900M weekly active users, and over 50M subscribers. Enterprise business accounts for 40% of total revenue, expected to match consumer business by year-end. A new advertising pilot program achieved $100M annualized recurring revenue within weeks.

Impact: OpenAI is preparing for an IPO later this year, with enterprise AI demand continuing to surge and advertising emerging as a new growth point.

Anthropic was listed as a “supply chain risk” by the U.S. Department of Defense after refusing to lift restrictions on autonomous weapons and mass surveillance. The company subsequently sued the government, with a federal judge ruling on March 26 to prohibit the designation. However, on the same day, a misconfigured content management system exposed approximately 3,000 internal documents, including draft blog posts about Claude Mythos warning of “unprecedented cybersecurity risks.”

Five days later, source code maps accidentally included in the Claude Code release exposed 512,000 lines of source code, revealing internal model codenames, “undercover mode,” and more details about Mythos. Multiple service outages occurred from late March to early April, coinciding with user surges triggered by the Pentagon dispute. On April 4, Anthropic cut off subscription access for third-party agent tools (including OpenClaw), affecting an estimated 135,000 OpenClaw instances.

Impact: Anthropic struggles between ethical positions and commercial pressures, with consecutive security incidents raising questions about its operational reliability.
