Retail is the whole consumer-spending universe, $35 trillion in 2025. Online is 1 channel inside it, 1 dollar in 5. The analysts cannot even agree on the 2030 total, $36 trillion to $51 trillion, because each counts retail differently. So I make no call on the total. I make the call on the mix.
By 2030 retail stops being a place. The transaction starts in the feed, the search box or the agent, and the store becomes the warehouse and the returns desk. Physical retail is not dead. Passive physical retail is.
My call: 3 in 10 retail dollars are bought online or by an AI agent by 2030, against the analysts' 1 in 4. The extra comes from 2 waves the trend line does not contain: agents that shop for you, $3 to $5 trillion by 2030 on the consultancies' count, and social commerce, TikTok Shop, SHEIN, Temu, where the feed is the shop window.
The money confirms it: retail media, the ads retailers sell on their own shopper data, was $184 billion in 2025. Consensus says $312 billion by 2030. I say $400 billion. Amazon owns half of it, my 2015 call, landed on card 41.
Sellers say omnichannel. The tape says most retailers still run separate inventory, loyalty, online and store systems. By 2030 disconnected retail is not omnichannel. It is dead weight.
The warning: retailers spend on AI theatre while margins stay hostage to logistics, labor and returns. The winners use data and automation to cut friction, stockouts, returns and the cost of winning a customer.
On track
