Capex Forecast

Companies spend money on two very different things. One is ongoing costs like salaries, electricity, or advertising. The other is acquisitions that last many years: factory buildings, machinery, trucks, server halls. This second group is called Capital Expenditures in English, Capex for short. A capex forecast is a company’s public announcement of how much of this it plans to spend in the coming year. It is usually stated when quarterly results are presented, often as a range such as “between 90 and 100 billion dollars.”

What the number reveals about the AI boom

Artificial intelligence requires enormous amounts of computing power. This computing power resides in data centers: large halls full of specialized chips, cooling systems, and power connections. Such halls are classic capital expenditures. When a corporation significantly raises its capex forecast, it is indirectly saying: We expect demand for AI to keep growing.

That’s why investors now watch the capex forecasts of Microsoft, Alphabet, Amazon, or Meta almost as closely as their profits. Combined, these corporations plan to spend triple-digit billions of dollars per year. A large portion of this ends up with chipmakers like Nvidia. A customer’s forecast is thus a revenue promise for its suppliers.

The stock market’s reaction is not always positive. A high forecast can signal confidence or trigger fear. That’s because the money is spent upfront, while the profit from it remains uncertain. Some stock prices have fallen after a raised capex forecast because investors had doubts about whether the spending would pay off.

How such a number comes about

The finance department collects the plans from all divisions. How many data centers are to be built? How many chips have been ordered? Which plots of land and power lines are already secured? This results in a sum that the executive board adjusts up or down and then publishes.

The distinction between expenditure and cost on the balance sheet is important. A data center is not booked entirely as a cost in the year it is built. Instead, the amount is spread over its estimated useful life, roughly five or six years. This annual reduction in value is called depreciation. A high capex forecast therefore does not immediately reduce profit, but does so gradually over several years.

Forecasts are statements of intent, not contracts. They are often revised upward during the year as demand increases. They can also be delayed, for instance if chips or power connections are not available in time. That is precisely why experts always compare the old forecast with the new one: the direction of the change says more than the number itself.

Where the number shows up in the news

Four times a year, major publicly traded companies present their results. The announcements that follow almost always include a sentence about the planned level of investment. Phrases like “the company is raising its investment forecast to 120 billion dollars” refer to exactly this. The English term “guidance” means the same thing: an outlook provided by the company itself.

Such announcements move entire industries. Rising capex forecasts from AI companies support the share prices of chipmakers, networking firms, cooling technology providers, and even power utilities. Falling forecasts have the opposite effect. Anyone who understands this term can therefore make sense of many stock market headlines that at first glance sound like mere accounting.
