Every era had its leverage. Here is what it looks like now.

Leverage is the ability to get more out of the business than you put into it, because you control something others need and cannot easily get. Every economic era has had its own version of that scarce thing.

In agrarian economies it was land. Whoever held the fertile fields set the terms for everyone who worked them. In the industrial era it was capital and machinery: a factory let a few owners produce at a scale no craftsman could match.

In the twentieth century, leverage moved to distribution and brand. Owning the shelf space, the dealer network or the name customers trusted mattered more than owning the plant. Then software and the internet added network effects, where each new user made the product more valuable for the next.

Each of these moats rested on something being hard to copy. Land is fixed. Factories take years to build. Brands take decades of trust. Networks take a critical mass of users.

AI changes the pattern. Analysis, writing, code, design and even strategy can now be rented by anyone at almost no cost. The intelligence that used to set a company apart is becoming a commodity, available equally to you and to every competitor.

What stays scarce is what the law or a contract lets you keep for yourself: a granted patent, an exclusive licence, a trade secret, a proprietary dataset, a regulatory approval. These are not skills. They are rights. And rights cannot be prompted into existence by a competitor.

The businesses that keep their margins in the next decade will be the ones that deliberately acquire and protect those rights, not the ones with the cleverest AI stack.
