Apple’s stock fell 5% Thursday, wiping out $202 billion in market value, after reports suggested delays in rolling out an upgraded version of its Siri assistant.

The tech giant had planned to release new Siri features with iOS 26.4 in March, but testing issues may push some updates to iOS 26.5 in May and iOS 27 in September.

Problems include Siri relying too heavily on ChatGPT responses instead of Apple’s own AI, despite agreements to use Google’s Gemini AI models.

Analysts say Apple’s success with AI features and the revamped Siri is critical for its stock, which is also facing pressure from rising memory and storage costs for new iPhones, MarketWatch has reported.

Despite these challenges, experts note that Apple is managing supply constraints better than competitors, and strong AI execution this year could boost investor confidence.
