Key takeaways from an industry expert interview on Meta Business Agents:

Strong ad spend: Q1/Q2 spend up 30%+ YoY at the expert's company, Q3/Q4 forecast 20%+; two-year stacked growth topped 60% in Q2 — slowdown is just tough comps.
Reels is the biggest tailwind, rising from under 30% to near 40% of Meta spend (4-5pt tailwind); click-to-messaging ads roughly doubled as a share of spend, lifting CPMs.
Shopping ads (Amazon/Shopify integrations) keep users on-platform; overlay ads on creator content are genuinely new incremental inventory.
Business Agents lead with analytics, unifying multi-stack data so even one-person businesses get a single metrics view — the BI layer is the real new thing. Brand linking (paid brand names becoming live links when mentioned in WhatsApp/Messenger/IG chats) may evolve into an auctioned ad product; current $10-30/month pricing drives upgrades.
The expert pegs long-term ad TAM including chatbots at $3T+ annually, with micro/small businesses the biggest beneficiaries of AI ad tools.
