Morgan Stanley: The adoption rate of AI is increasing.
In a report released on November 6, 2025, Morgan Stanley pointed out that corporate adoption of artificial intelligence (AI) is shifting from the “storytelling” stage to the “proving results” stage, with more and more companies achieving measurable financial and operational gains. This trend not only validates the long-term value of AI, but also reveals new market dynamics to investors.
According to Wind Trading Desk, the report notes that the “measurable” benefits companies are gaining from AI are steadily increasing. The core impacts for investors are:
First, the efficiency improvements brought by AI will support profit expansion for companies. It is expected that by 2026, the net profit margin of the S&P 500 index will increase by 30 basis points due to this.
Second, market leadership will spread from a handful of tech giants to a broader group of “AI adopters”, providing investors the opportunity to capture growth outside the technology sector.
Finally, although the market is worried about a valuation bubble, the report uses detailed data to compare the current situation with the dot-com bubble of 1999, demonstrating that the solid fundamentals behind today’s high valuations provide confidence for long-term investor holdings.
Quantifiable AI Benefits Become Increasingly Apparent, Momentum of Application Continues to Strengthen
The measurable benefits companies are gaining from AI are steadily increasing. Through systematic analysis of around 7,400 earnings call transcripts and 6,100 industry conference summaries, Morgan Stanley found:
Among companies identified by analysts as “AI adopters,” 24% mentioned quantifiable AI impact in Q3 2025, higher than 21% in Q2 and 15% in the same period last year.In the broader S&P 500 index, 15% of companies reported measurable AI benefits in Q3 2025, also above the Q2 figure of 14% and 11% for the same period last year.
These gains are mainly seen in six areas, with “productivity improvement” (such as operational efficiency) and “financial impact” (such as cost savings and revenue growth) being mentioned most often. It’s noteworthy that the AI benefits companies are currently mentioning are more focused on cost reduction, which is mentioned almost twice as frequently as revenue growth. This indicates that, in the early stage of AI integration, companies are mainly focused on boosting internal efficiency and streamlining operations through technology, rather than immediately achieving top-line growth.
Tech and Communication Sectors Lead, While Industry-Wide Penetration is Underway
The report clearly states that AI application is not limited to the tech sector. While technology firms lead in demonstrating quantifiable AI benefits, the catch-up momentum in other industries is also significant.
Industry Leaders: In Q3 2025, 39% of companies in the tech sector mentioned quantifiable AI benefits, ranking first. Next are the communication services sector (26%) and the financial sector (16%).
Fastest Growing Catch-Ups: In year-on-year terms, the energy sector showed the most remarkable progress, with the proportion of companies mentioning quantifiable AI benefits surging from 0% last year to 10%. The tech sector’s penetration also rose from 26% to 39%, demonstrating a continuing deepening trend.
Industry Detailed Groups: Within the tech sector, the “software and services” sub-industry showed the most prominent AI application results, with as many as 59% of companies reporting quantifiable benefits, far exceeding other sub-industries.
This cross-industry diffusion trend validates Morgan Stanley’s view that in the next 6–12 months, market leadership will spread from a few giants to a much broader set of industries, with sources of profit growth becoming more diversified.
This Is Not 1999: Essential Differences Between the Current Market and the Dot-Com Bubble
As AI triggers a capital expenditure boom, fears of a repeat of the 1999–2000 dot-com bubble have arisen in the market. Morgan Stanley’s report deeply analyzes this and reaches one clear conclusion: the current era is fundamentally different. Market fundamentals are much healthier today than in 2000.
1. Higher index quality, better cash flow: Today’s large caps have a median free cash flow yield of about 3.5%, almost three times the 1.2% seen in 2000. In addition, after adjusting for profit margins, the forward P/E for the S&P 500 is about 35% lower than at the peak of the dot-com bubble. This indicates that today’s market is led by more profitable, cash-generating companies.
2. More reasonable valuations for top companies, stronger profitability: The top 10 stocks by weight in the S&P 500 have a median forward P/E of 31x, much lower than the 44x peak in 1999 and even below the 35x level in 1998, a 13x valuation discount compared to 1999. More importantly, their median operating profit margin is more than 20% higher than in 1999.
3. Completely different macro environment: The 1999–2000 period was a classic late economic cycle, with the Federal Reserve raising rates to curb overheating. Now, the market is emerging from a “rolling recession” into the early stages of a “rolling recovery,” with the Fed in a rate-cutting mode. Easy monetary policy provides strong support for high valuations.
4. Healthier credit markets: The telecom construction boom in the late 90s was largely debt-driven, with most participants rated BBB/BB and rapidly rising leverage. By contrast, today’s AI capital expenditures are led by “hyperscale computing firms” with extremely strong balance sheets—such as Microsoft (AAA rating), Google, and Meta (AA rating)—which have ample cash reserves and low reliance on debt markets. Modern credit markets are also much deeper and broader, with healthier risk dispersion than in the past.
In summary, Morgan Stanley’s report paints an optimistic picture for investors of accelerated AI application, continuing improvement in profitability outlook, and potential expansion in market breadth. At the same time, through rigorous data comparison, the report robustly refutes “bubble theory,” believing that with strong underlying fundamentals and a favorable macro environment, current market valuations are sustainable.
