A new study led by Yale University suggests that investors are increasingly rewarding businesses expected to benefit from the rapid expansion of AI, with companies linked to growing AI adoption consistently delivering stronger stock market performance.
The research examined an enormous dataset containing 380 trillion AI tokens, making it one of the most comprehensive analyses of real-world AI activity conducted to date. The data was obtained from OpenRouter, a platform that connects users with more than 400 AI tools, including DeepSeek, GPT, and Claude. Covering the period from January 2024 to April 2026, the dataset represents roughly 2% of global monthly AI usage from millions of anonymous users.
According to the researchers, firms with the greatest exposure to AI-related growth outperformed those with the least exposure by an average of 0.64% each week. They describe this performance gap as the “AI Premium,” reflecting investor confidence that AI will improve future productivity and profitability.
The findings indicate that the impact extends well beyond technology companies. Businesses in retail, consumer goods, manufacturing, and other industries requiring significant physical infrastructure also appear to benefit from positive investor expectations surrounding AI. The researchers say this demonstrates a growing belief that AI has the potential to reshape operations across many sectors rather than remaining limited to software companies.
To measure AI adoption, the researchers developed a weekly indicator called the “AI Factor,” tracking changes in global AI consumption. They then compared this measure with stock market performance to identify companies whose share prices rose alongside increased AI activity. Their analysis suggests that investors are assigning higher valuations to businesses expected to benefit from advances in AI, even if those gains have not yet materialized.
The strongest AI-related market effects were observed in Europe, the U.S., and other developed economies where investment, infrastructure, and advanced AI development are concentrated. The trend appeared weaker in China and many emerging markets.
The study also found that investors place greater value on intensive AI usage involving advanced commercial models, experienced users, paid subscriptions, and more sophisticated prompts rather than casual experimentation with open-source or free systems.
Researchers also explored the relationship between AI adoption and employment by combining stock market information, labor statistics, and AI usage data. They found that occupations centered on communication, teaching, persuasion, and interpersonal interaction received more favorable market expectations than jobs dominated by repetitive analytical or routine scientific tasks.
The report additionally noted a sharp rise in agentic AI, with autonomous systems accounting for more than 50% of AI token usage by 2026. Early evidence suggests that companies positioned to benefit from this next generation of AI are beginning to receive higher market valuations.
As the public becomes increasingly aware of how businesses like AI Maverick Intel Inc. (OTC: AIMV) are leveraging AI in their product offerings, we could see the premium attached to AI use in enterprises rising significantly.
