Revenue at US companies providing AI infrastructure has risen by $400bn since 2022, which at first glance seems to suggest that AI has been a meaningful driver of economic growth recently. But official numbers tell a different story. AI technology has lifted real US economic activity by about $160 billion since 2022, or 0.7% of GDP. Yet only around $45 billion, or 0.2% of GDP, of AI-spurred growth has been recorded in official statistics. That leaves roughly $115 billion uncounted, according to the analysts.
