This week in FMTC’s Affiliate Roundup: Mobile apps are pushing users to web checkout to avoid app store fees and unlock more revenue control. Levanta now lets Amazon and Walmart sellers book flat-fee creator deals with affiliate-level performance tracking. Just 1.6% of Amazon’s third-party sellers drive half of U.S. marketplace sales, highlighting growing concentration at the top.


• Mobile apps are shifting users to web-based checkout and subscriptions to bypass app store fees, capture first-party data, and boost revenue as app-to-web monetization goes mainstream.

• OpenAI is expanding its agentic commerce tools, enabling ChatGPT to handle product discovery and in-chat checkout as it deepens its push into AI-powered shopping.

• Levanta’s new Paid Placements feature lets Amazon and Walmart sellers secure flat-rate creator content while measuring results end-to-end through affiliate-level performance tracking and conversions. 

• New research from HypeAuditor and the IMTB finds that clearly tagging sponsored posts with #ad doesn’t harm engagement and can actually boost interaction and trust for influencers.

• Just 1.6% of Amazon’s third-party sellers — under 8,000 accounts — now generate half of the U.S. third-party GMV, showing intensified concentration at the top.

• OpenAI has begun rolling out ads in ChatGPT, making the chatbot a new advertising platform with guardrails to keep ads outside sensitive chats as conversational AI becomes a fresh battleground for ad dollars.

• Retail data shows online shoppers are clicking more but converting less. Clicks rose ~2% in 2025 while transactions fell ~5%, with average order value up as buyers research extensively before consolidating purchases.
