a16z Weekly Chart Report: Agent Shopping Blocked by E-commerce Platforms; Consumer Intent Remains Lagging

An a16z weekly chart report indicates that the agent economy is facing headwinds. Cloudflare data shows that 403 Forbidden responses received by agents and crawlers have increased significantly since summer, roughly doubling compared to earlier levels. The article cites NRF data stating that return rates and return costs have doubled and tripled respectively since 2019. It also references a survey indicating that 42% of consumers completely distrust AI shopping agents. Similarweb data reveals that AI shopping activity occurs primarily in the intermediate stage between discovery and purchase, rather than at the checkout point.
