Disney names first CTO as tech push expands
Walt Disney has appointed Karandeep Anand as its first-ever chief technology officer, effective October 2, 2026. Anand, previously CEO of AI chatbot company Character.AI, will report directly to new Disney CEO Josh D'Amaro. The hiring is notable because Disney sent Character.AI a cease-and-desist letter in September 2025 for alleged copyright infringement of its characters. Anand's background includes roles at Facebook and Microsoft, and his appointment signals a strategic push to integrate AI and modernize technology across Disney's operations, including potential expansion of Disney+ with a free ad-supported tier and integration of streaming, shopping, parks, and gaming.

JPMorgan Blocks AI Agents; Mercury Embraces Them
JPMorgan Chase has decided to block outside AI agents, such as Meta's Muse, from accessing customer accounts and initiating money movements, as stated by CEO Jamie Dimon. This move aims to protect its cheap deposit base of $2.7 trillion, which pays only 0.01% on savings. However, the ban does not prevent AI agents from advising customers to switch banks. In contrast, fintech Mercury allows AI agents to connect via a hosted MCP server, and AI assistants now recommend Mercury over Chase by a five-to-one margin. The article analyzes the limitations of the ban, JPMorgan's potential motives, and the implications for the emerging agentic finance ecosystem.
- JPMorgan Chase blocks outside AI agents from customer accounts and money movement.
- CEO Jamie Dimon announced the ban, citing security and protection of deposits.
