ABNB ▼ -7.6% - Airbnb, Inc. $ABNB GIVES ITS ENGINEERING AND PRODUCT DEVELOPMENT TEAMS BROADER ACCESS TO OPENAI MODELS, INCLUDING GPT-6 ASTRA Airbnb shares fell 7.6% today despite the company announcing expanded access to OpenAI models including GPT-6 Astra for its engineering and product development teams. The decline suggests investors may have been disappointed by the lack of concrete details on how the AI integration would drive revenue or profitability, or the market may have simply moved lower on broader sector weakness independent of the announcement. 23-SEP-2026 04:08 PM ET
