Culminating Point

Anyone attacking becomes a little weaker with every step forward. That sounds contradictory, but the reason is simple: the path back to one’s own supply lines grows longer. Troops tire, equipment wears down, losses add up. At some point there is a moment at which the attacker still just holds the upper hand — and after which he no longer does. This turning point is exactly what is called the culminating point, or in German, the Kulminationspunkt. The Prussian military theorist Carl von Clausewitz described it roughly 200 years ago.

Why the turning point is often recognized too late

The tricky thing about the culminating point is that, from the inside, it hardly feels like a turning point. Whoever is currently succeeding sees mainly the success. The costs of that success sit elsewhere on the balance sheet and grow inconspicuously. Clausewitz’s warning was therefore: the most dangerous moment is not the defeat, but the victory just before it.

An attacker who shoots past his culminating point does not simply lose momentum. He suddenly finds himself far out in front, without reserves, with long supply lines — and therefore vulnerable. Napoleon’s campaign to Moscow in 1812 is the classic example. He captured the city and had nevertheless already lost, because he had long since passed the point.

For analysts and investors, the term is therefore of interest. It describes a situation in which the visible success figures and the actual strength diverge. One is not looking for the moment of failure, but for the last moment before it.

What brings the point about

Behind the culminating point there is always a mismatch between what is being consumed and what is being replenished. Militarily, that means ammunition, fuel, provisions, rested soldiers. Economically, it means capital, personnel, computing power, or simply the patience of investors. As long as supply flows faster than consumption, strength grows. Once that ratio tips, the curve tips with it.

An image makes it tangible: a runner in a mid-race sprint at first gets faster. His lead grows visibly. But his oxygen reserve has been dropping the whole time. The culminating point is the last step at which he still gains ground. After that, he draws on substance that is no longer there.

It is important to distinguish this from a peak in the sense of a record. A record value can be determined exactly in hindsight. The culminating point, by contrast, is a strategic judgment about the future: from here on, further advancing no longer pays off. Clausewitz’s practical recommendation was therefore to switch to the defensive in time — that is, to secure the advantage rather than gamble it away.

The term in the AI race and in market commentary

In business texts, the culminating point tends to come up when someone is warning of overextension. A company expands rapidly into new markets, opens locations, buys up competitors. Revenue and attention rise. At the same time, debt and complexity rise along with them. The analysts' question then is: where is the point beyond which growth costs the company more than it brings in?

The term currently comes up especially often in commentary on the AI boom. Major providers are building data centers for tens of billions of dollars and training ever-larger models. Each new model generation costs a multiple of the previous one, while the gain in capability turns out smaller. Skeptics speak of an approaching culminating point: beyond some point, the next, even larger model no longer pays off.

However, the term should not be confused with a forecast. It names a pattern, not a date. Whether a race has already passed its culminating point can usually only be said in hindsight. Anyone who reads it in a headline should therefore above all ask one question: which concrete figures actually indicate that supply is growing scarcer?
