What happened?
Walmart updated its Media Library operating guide on October 6, 2026. According to the guide, sellers can upload videos and rich-media content such as Brand Highlights through Seller Center. Video files are limited to 100 MB, titles may not exceed 200 characters, and video processing typically takes less than 60 seconds. The platform also emphasized that AI-generated content must be accurate and truthful, that sellers must own the rights required to use the content, and that the content must comply with product detail policies. Some categories, including alcohol, tobacco, and firearms, may not be eligible for the related rich-media features. The update affects daily asset uploads and content reviews for brand sellers, sellers using AI-generated main images or videos, and cross-border teams seeking to improve conversion through video. If AI assets exaggerate a product’s size, efficacy, color, accessories, or use results, the content may be removed and could create product compliance or account risks in serious cases.
What does this mean for cross-border sellers?
Walmart brand sellers can use videos and Brand Highlights in Seller Center to showcase products, but assets must meet file, title, and product detail policy requirements. AI-generated content that exaggerates product information or lacks the necessary rights may be removed and could create product compliance or account risks.
