The "AI Premium" phenomenon: Stocks of companies that investors consider future beneficiaries of AI grow 0.64% faster per week.
The market has already begun rewarding companies that investors believe will benefit from the adoption of artificial intelligence — even if those companies are not yet actively using AI. A study conducted by economists from several leading universities has identified a persistent gap in returns between such "potential beneficiaries" and the rest of the market. This gap has been termed the "AI premium."
The analysis is based on a colossal dataset — 380 trillion tokens collected by the OpenRouter platform from January 2024 to April 2026. This dataset covers over 400 models, including GPT, Claude, and DeepSeek, and represents approximately 2% of global monthly AI consumption. To assess the impact of technology on the stock market, the researchers developed a special indicator — the "AI factor" — which records changes in global neural network consumption on a weekly basis.
Companies were then divided into two categories: those whose stocks show high sensitivity to the growth in AI popularity, and those whose securities barely react to such changes. Comparing the returns of these groups revealed a significant gap. Stocks of "sensitive" companies yielded investors an average of 0.64% more per week. This difference was defined as the "AI premium."
Key Findings and Unexpected Patterns
The first and perhaps most important discovery: the premium has extended far beyond the technology sector. Not only IT giants are seeing higher returns, but also retailers, consumer goods manufacturers, and even representatives of heavy industry. Investors expect a broad increase in labor productivity across all areas of business. As one of the study's co-authors, Aleh Tsyvinski, noted, the AI story is not just a technological narrative but a much broader one, affecting companies and workers in all parts of the economy.
The second unexpected factor is geography. The bulk of the "AI premium" is concentrated in the US and Europe. These regions are closely tied to the creation of infrastructure and the construction of modern data centers. In China and emerging markets, this effect is significantly weaker. Market mechanisms reward proximity to cutting-edge developments, which are currently available to only a few.
The third discovery concerns the structure of the users themselves. It would be logical to assume that the market is driven by millions of ordinary users. However, a detailed analysis revealed a completely different picture. The financial premium is formed exclusively by the professional segment. This includes complex, lengthy queries and paid subscriptions. As co-author Nicola Borri emphasized, the premium is set precisely by professionals working with advanced AI, not by those who occasionally try free or open models. Investors value the depth of technology integration, not mass reach.
My comment: This pattern is an excellent signal for long-term investors. 0.64% per week may seem insignificant, but on an annualized basis, it provides an impressive head start. It is important to understand: the market is advancing not current financial performance, but expectations. A company may not use AI at all today, but if investors believe in its prospects, they will actively buy its securities. This confirms that the AI era is not just hype, but a structural shift that has already begun to reshape market capitalization.
