Artificial intelligence is becoming a major force behind business investment in the United States, with spending in AI-related categories climbing sharply during the second quarter of 2026 and reaching a record annualised rate of $1.5 trillion.
Commerce Department data shows private investment in AI-related sectors rose by roughly $300 billion compared with the same period a year earlier, an increase of about 25 per cent. The latest figures mark one of the strongest periods of AI-driven capital spending in recent years and point to continued demand for computing infrastructure and digital technology.
The biggest increase came from investment in computers and peripheral equipment, which has more than doubled over the past two years. Spending on communication equipment, software and data centres also continued to rise, contributing to the overall increase.
Over the past two years, total business investment in AI-related categories has grown by about $500 billion, or 50 per cent. The trend suggests that companies are continuing to allocate large amounts of capital to hardware, networking equipment and computing capacity linked to AI deployment and development.
Economists have increasingly focused on AI investment as a contributor to broader economic activity. Estimates suggest that direct AI investment has accounted for roughly a quarter to a third of recent US GDP growth, making it one of the stronger sources of private-sector expansion.
The composition of the investment surge is particularly notable. While software spending remains substantial, much of the recent acceleration has been concentrated in physical infrastructure such as servers, networking equipment and computing systems. That reflects the growing demand for the hardware required to train and run AI models at scale.
Analysts say the current investment cycle differs from earlier technology booms because it is being driven by a broad range of industries rather than a small group of technology companies. Manufacturers, healthcare providers, financial institutions and other large businesses are investing in AI systems to improve productivity, automate processes and support new digital services.
The strength of AI-related investment has helped offset weaker activity in some other areas of business spending. Corporate investment has remained relatively resilient despite higher borrowing costs and ongoing uncertainty around trade policy and global growth.
Whether the current pace can be sustained remains an open question. Some economists have warned that AI infrastructure spending could moderate if demand slows, financing conditions tighten or companies become more cautious about capital expenditure. Others argue that the build-out of computing capacity is still in its early stages and could continue for several years.
For now, the latest investment figures suggest that AI has become an important driver of US business spending, with companies committing record levels of capital to the technology and the infrastructure that supports it.
