Overview

• Meta will begin using voice and text interactions with Meta AI to tailor feeds and advertising across Facebook, Instagram, WhatsApp and other apps starting December 16, with in‑app and email notices to users beginning October 7.
• Users cannot opt out other than by not using Meta AI, and Meta says conversations touching on religion, sexual orientation, political opinions, health, racial or ethnic origin, philosophical beliefs or union membership will not inform advertising.
• Personalization from AI chats depends on Accounts Center linkage, so WhatsApp interactions will not shape Facebook or Instagram unless accounts are connected, and the change will initially exclude the EU, the UK and South Korea.
• OpenAI’s Instant Checkout is live in the United States, letting ChatGPT users buy compatible items directly in chat for single‑product purchases today, with carts, more merchants and wider regional availability planned.
• OpenAI open‑sourced its Agentic Commerce Protocol built with Stripe, with Etsy as the first implementation and Shopify support promised, as analysts highlight risks of algorithmic gatekeeping and potential disadvantages for small merchants.
