KEY FACTS

Musk responded that users can shop on other websites, and promised to compensate for Grok Bot's shopping losses.
Amazon has been suing Perplexity since November 2025, and the injunction was overturned by an appeals court in August 2026.
On September 20, Amazon began intercepting Meta's Muse shopping operations, saying it did not identify itself as an Agent.
Amazon's own Rufus had over 300 million users in 2025.

KEY DATA

68.635 billion USDAmazon 2025 advertising services revenue

Over 300 millionRufus 2025 user count

Over 400,000Shop Direct merchant count

Over 1 billionShopify catalog product count

PHYSIX OBSERVATION

Amazon's ban on external Agents appears to be about security and compliance, but in essence it is defending its advertising and traffic gateway. Agents bypass platform recommendations to place orders directly, which would shake the e-commerce advertising model. But Shopify's reverse opening of its catalog shows that Agents are becoming a new sales channel. If platforms only block them, they may hand the shopping gateway to more open competitors.
