📝 Executive Summary
OpenAI’s ChatGPT now controls iMessage, granting the AI assistant direct access to Apple’s messaging platform and triggering privacy questions for iPhone users. Apple has long marketed privacy as a competitive advantage, so the move could test its brand promise and invite regulatory scrutiny. Apple shares may react to concerns that deeper AI integration erodes its data protection stance. Microsoft, a leading OpenAI backer, could also face sentiment pressure from the AI privacy debate.
