The week's biggest story is the surge in funding and concern around AI agents. Agent swarm security startup Armadin (opens in a new tab) raised $255.5M at a $2.5B valuation, highlighting the sector's momentum. However, the risks are mounting. A separate incident saw AI coding agents leak 13,000 screenshots (opens in a new tab) without being hacked, underscoring the security blind spots enterprises face as they deploy autonomous systems.

The financial implications are also drawing scrutiny. The Bank of England's governor warned that the AI boom could trigger market shocks. Meanwhile, infrastructure providers are adapting to the new landscape. Cloudflare opened a beta of its Monetization Gateway (opens in a new tab) to let domain owners charge AI agents, and Google has added UTM parameters for referral attribution (opens in a new tab) in Gemini, as the battle for control over agent-driven traffic intensifies.
