For most of commerce’s history, the middleman was a merchant — someone who bought goods, held inventory and sold them on. The chain was physical, and the margins were earned by moving goods.
That chain has been replaced. The new middlemen of commerce do not hold inventory; they hold attention. They do not move goods; they move decisions. And their share of the value is taken not from the goods but from the moments — the click, the order, the recommendation. They are not merchants. They are the toll collectors of the digital economy.
The inventory-less middle
The defining feature of the new middlemen is that they do not take possession of anything.
The platforms connect buyers and sellers, but the goods move directly from the seller to the buyer. The middleman takes no inventory, no risk of stock, no cost of storage. What they provide is the marketplace — the discovery, the trust, the payment, the logistics coordination. Their margin is taken from the transaction, not from the goods.
This is a fundamentally different economics: the merchant earned from spread; the platform earns from toll.
The attention as the asset
The new middlemen’s true asset is not goods but attention — and attention is the scarce resource.
The buyer has limited attention and the seller has a need to be seen. The middleman owns the channel through which the two meet: the search, the feed, the marketplace, the recommendation. Every seller must pass through the channel, and the channel takes a share. The more the attention concentrates, the higher the toll — which is why the platforms have grown so valuable.
This is the insight that explains the platforms’ profitability: they monetize the moment of decision, not the product.
The data advantage
The new middlemen compound their position with data that no merchant ever had.
They see every search, every click, every purchase, every abandoned cart. They know what you are considering before you buy, and they know what you bought before and after. The data lets them optimize the moment — the price shown, the product suggested, the timing of the push — with a precision that a physical merchant could not approach. The toll is collected by the most informed toll-collector in history.
The data is the moat: the more the transactions flow through, the sharper the optimization, the harder it is to bypass.
The fees that compound
The share the new middlemen take is not a single fee; it is a stack of them.
There is the listing fee, the transaction fee, the payment fee, the advertising fee for prominence, the logistics fee for fulfillment. Each is small; together they can take a substantial slice of the seller’s margin. The seller who wants to be seen must pay for the seeing, and the paying is continuous. The toll is small at each gate and large at the end.
This is why the sellers’ complaints about platforms are so consistent: the fees compound, and the alternative to paying them is invisibility.
The dependency it creates
The new structure creates a dependency that is economic and almost inescapable.
The seller depends on the platform for discovery, and the platform depends on the seller for supply. But the dependency is asymmetric: the platform can function with many sellers, while an individual seller cannot easily function without the platform. The balance of power sits with the channel. The seller’s business is, in effect, conducted on terms set by the middleman.
This is the structural tension of the new commerce, and it is not going away.
The consumer’s position
For the consumer, the new middlemen offer genuine convenience — and a quieter cost.
The convenience is real: the comparison, the recommendation, the seamless payment, the fast delivery. The cost is the concentration itself — the narrowing of what is shown, the elevation of what is sponsored, the shaping of choice by the platform’s incentives. The consumer sees a marketplace; the marketplace sees a customer, with all the information that implies.
The consumer is not the middleman’s customer; they are the middleman’s inventory — the attention being sold.
The honest conclusion
The new middlemen of commerce are not merchants, and they have changed what middlemen are.
The merchant moved goods; the new middlemen move decisions. The merchant took a margin; the new middlemen take a toll, continuously, on the moments of the digital economy. Their power is built on attention, data and the compounding of small fees — and it is as structural as any infrastructure in the economy.
The question is not whether the toll will be collected; it is whether the collectors will be held to the standards of the infrastructure they have become. The platforms are the public squares and marketplaces of the modern economy, and the terms on which they operate shape the commerce of everyone within them. The new middlemen are not going anywhere. The debate is about what we demand of them, and who the commerce of the future truly serves.
