Private Investment Contribution to US GDP Growth

## What this measures

Percentage points of annualized real GDP growth that came from gross private domestic investment: business spending on equipment, structures and software, housing, and the change in inventories.

## Why it matters

Investment is the most volatile part of GDP and often turns first in a slowdown. Business equipment and software spending also carries the AI build-out into the national accounts.

## How to read it

Inventories swing this series hard: a quarter of restocking adds growth that the next quarter often gives back. Read it over several quarters and beside the consumer and trade contributions.

## What it does not say

It does not separate inventories from fixed investment, or business from residential investment. It is revised with each BEA estimate.
