TLDR: A recent study highlights that generative AI tools generated an estimated $97 billion in consumer surplus in the U.S. in 2024, a significant economic contribution largely overlooked by traditional GDP measurements. This ‘welfare revolution’ benefits users directly, dwarfing the revenue earned by AI companies.
While official economic indicators like Gross Domestic Product (GDP) may not yet fully reflect the impact of Artificial Intelligence, a new study reveals that generative AI tools contributed an astounding $97 billion in consumer surplus to the U.S. economy in 2024 alone. This substantial figure, detailed in research by Avinash Collis, an assistant professor at Carnegie Mellon University’s Heinz College, along with Felix Eggers, Erwin Diewert, and Kevin Fox, suggests a ‘welfare revolution’ is already underway, even if a ‘productivity revolution’ is still brewing.
The findings indicate that the economic benefits of generative AI are primarily accruing to users rather than the companies developing these technologies. For context, the $97 billion in consumer surplus significantly overshadows the approximately $7 billion in U.S. revenue recorded by major generative AI players like OpenAI, Microsoft, Anthropic, and Google last year. This disparity explains why AI’s true economic contribution remains largely invisible in conventional GDP calculations.
Economists have encountered similar phenomena in the past, notably with the introduction of personal computers, which took nearly two decades to show a significant impact on measured productivity. As Nobel laureate Robert Solow famously quipped in 1987, ‘You can see the computer age everywhere but in the productivity statistics.’ The current situation with AI appears to echo this historical pattern.
To bridge this measurement gap, the researchers developed a new metric called GDP-B (B for benefits). Instead of focusing on what people pay for a good or service, GDP-B assesses what individuals would need to be compensated to give up that good or service. Their methodology involved a nationally representative survey of U.S. adults conducted in late 2024, which found that 40% were regular users of generative AI. A subsequent survey determined that the average user would require $98 to forgo these tools for just one month. By multiplying this average valuation by an estimated 82 million users and then by 12 months, the $97 billion annual surplus emerges.

This research underscores the growing importance of measuring benefits alongside costs, especially as more digital goods and services become available for free. The absence of AI’s full value in GDP statistics does not equate to its absence in real-world impact. The study concludes that AI’s value proposition is already embedded in millions of browser tabs and smartphone keyboards, signifying a profound, albeit statistically elusive, transformation in consumer welfare.
