AI talk dominates corporate communications. In a recent BCG analysis of 4,800 quarterly earnings calls, it was the most-mentioned topic by CEOs globally. But which companies are translating that talk into measurable performance—and how?

Most evidence on AI adoption today comes from these communications or from self-reported surveys. Both have limitations: corporate communications reflect what company leaders think investors want to hear, and surveys reflect what companies say about themselves. To cut through the noise, we developed an outside-in measure of AI adoption and applied it to more than 600 US public companies. Our findings push back on three threads of the public conversation around AI:

• The public narrative is that AI adoption is widespread and that companies are seeing real benefits from it. An FT analysis of S&P 500 filings found 75% of companies mentioned AI on earnings calls in the past year, with 87% of those mentions wholly positive. In contrast, we find that only 6% of firms in our sample qualify as real adoption leaders. But this select group is capturing meaningful value from AI, with industry-adjusted total shareholder returns (TSR) over the past three years running 9 percentage points above median.
• Many analysts argue AI value is a hype story driven by investor exuberance rather than fundamentals. But among the leading 6%, return outperformance is driven entirely by fundamentals—revenue growth and margin expansion—not by higher price-to-earnings (P/E) multiples.
• Public discourse frames AI as a tool for increasing efficiency and reducing headcounts. The recent wave of layoff announcements referencing AI reinforces this narrative. However, among the leading 6%, the dominant path to value generation is growth, not efficiency—and these firms are increasing headcount at a 3 percentage points higher compound annual growth rate (CAGR) than the median firm in our sample (between 2022–2025).

What’s more, by studying AI adoption leaders, we’ve traced their journey—identifying the strategies that enabled these companies to translate AI into competitive advantage.
