AI can become genuinely useful while investment in it still outruns durable returns. That tension makes “dot-com boom 2.0?” a fair question—but the historical analogy can illuminate risks, not tell us whether or when markets will crash.
What the dot-com comparison can—and cannot—tell us
The comparison is mainly about market structure, investment and realized returns in the United States. Both periods saw rapid appreciation in companies associated with a transformative technology and a large technology buildout. But a resemblance is not a forecast: Federal Reserve Vice Chair Philip N. Jefferson said on November 21, 2025, “Of course, much has changed over the past quarter-century, so history can only be a useful reference and not a predictor of future outcomes.”
That distinction matters for developers. Faster code generation may be valuable, but it does not establish that a company will earn a return on its AI spending—or that the technology has raised economy-wide productivity. The available evidence does not settle whether AI will produce a market crash or establish a comprehensive effect on developers’ jobs or purchasing choices.
AI and dot-com markets share a boom, but not the same foundations
Stock appreciation
In his November 2025 comparison, Jefferson noted that dot-com firms’ stock prices rose more than 200% from 1996 to 1999, while the Nasdaq stock price index rose about 215% over that period. He said AI-related firms had risen less over the period he assessed. These are historical figures and observations as of his speech, not current returns or a guarantee about what comes next. Federal Reserve Board: Jefferson’s November 21, 2025 speech.
#1 Best Overall
Earnings and valuations
Jefferson’s key distinction was the earnings base. Many dot-com companies had little or no realized earnings and relied on speculative revenue prospects. By contrast, the public companies most associated with AI generally had established and growing earnings streams at the time of his speech. He also said their price-to-earnings ratios remained below dot-com-era peaks.
That does not mean every AI company is profitable, that current valuations are sound, or that established companies cannot lose money on an investment cycle. It means the public-market leaders Jefferson was discussing did not have the same broad absence of earnings that characterized many dot-com firms. Earnings can cushion a company without proving that its AI spending will pay off.
How broad the speculation was
Jefferson counted more than 1,000 publicly listed dot-com companies near that boom’s peak, compared with about 50 publicly traded AI-focused enterprises by the measure he used. The groups are not defined alike: many companies use AI without being AI-focused, and the public count excludes private AI firms. Private capital can also make it harder to see how many businesses are presenting themselves as AI-focused. The figures therefore indicate a difference in public-market breadth, not a complete count of all firms exposed to either technology.
Rank #2
Debt and financing
Jefferson described limited reliance on debt among the relevant firms in both periods “for the most part.” That qualified observation should not be read as a balance-sheet inventory of the entire AI infrastructure ecosystem or every private financing arrangement. It does not establish that all AI-related investment is unleveraged.
What the investment contribution figures actually measure
A January 2026 analysis by the Federal Reserve Bank of St. Louis compares how selected investment categories contributed to real GDP growth. Its categories are information-processing equipment, software, research and development, and data centers. On this measure, the listed categories contributed 0.97 percentage points to real GDP growth in the first three quarters of 2025, compared with 0.81 percentage points in 2000. The 2025 average uses available Q1–Q3 data; the 2000 figure covers all four quarters. The 2025 total includes data centers, for which the source says comparable 2000 data were unavailable. Federal Reserve Bank of St. Louis: “Tracking AI’s Contribution to GDP Growth”.
| Investment category or measure | 2000 | First three quarters of 2025 |
|---|---|---|
| Information-processing equipment contribution to real GDP growth | 0.58 percentage points | 0.42 percentage points |
| Software contribution to real GDP growth | 0.11 percentage points | 0.35 percentage points |
| Listed AI-related categories’ combined contribution | 0.81 percentage points for the comparable categories listed; data centers unavailable for 2000 | 0.97 percentage points, including data centers |
| Share of GDP growth attributed to identified categories | 28% | 39%, or 36% excluding data centers |
These are annualized contributions to real GDP growth, not investment totals or rates of return. The 2025 contribution figures average available Q1–Q3 data, while the 2000 comparison uses the full year. The Q3 2025 data-center observation uses an imputed September value because the latest actual observation was August. Data centers are included in the 2025 total but lack a comparable 2000 figure, so the combined totals are not perfectly like-for-like.
Rank #3
The numbers show that these selected categories made a substantial contribution to measured growth; they do not show whether the investment earned its cost, increased productivity per worker, or produced social value. Nor does a declining contribution necessarily mean investment levels have fallen: as the St. Louis Fed explains, a category’s contribution can shrink when investment growth slows even while the level of investment remains elevated.

Why reported AI adoption is not the same as a productivity payoff
Federal Reserve analysis cautions that headline adoption rates do not reveal how intensively firms use AI. A company can report adoption while usage remains shallow. Likewise, experiments may find that AI improves particular tasks without showing a corresponding increase in aggregate productivity. Federal Reserve Board: “The AI Buildout and the Economy: Publicly Available Data to Assess AI’s Impact”.
For software work, generating or revising code faster is a task-level result. It does not automatically mean more software ships, quality improves, total engineering output rises, or the firm becomes more productive. Review, testing, security, product decisions and other bottlenecks can absorb the time saved. The cited analysis does not establish whether AI has or has not raised developer productivity overall.
Rank #4
Capital spending figures show the scale of the buildout, not its eventual payoff. The Federal Reserve’s accessible adoption data report that Amazon, Google, Meta, Microsoft and Oracle spent $131 billion on capital expenditure in Q4 2025 and $412 billion for the year—about 1.31% of U.S. GDP. The figures exclude leases. They describe five companies’ reported spending, not all AI investment or the return on that investment. Federal Reserve Board: “Monitoring AI Adoption in the US Economy, Accessible Data”.

History offers a mechanism, not a template. A 2004 New York Fed analysis found that computer and software spending—supported by Y2K preparations and internet growth—drove investment growth in the late 1990s before slowing in 2000. It also said overly optimistic profit expectations in communications industries likely contributed to an unsustainable investment surge in 2000. Useful technology and excessive investment can coexist: demand or expected profits may fail to justify the capacity built.

In a February 2026 speech, Federal Reserve Governor Michael S. Barr outlined conditional risks to the AI buildout: capability gains could stall, electricity supply or distribution could constrain data centers, capital could prove insufficient, or demand might not use the capacity built. Business-process transformation takes time, so near-term adoption may not immediately translate into productivity. Barr described a downside scenario in which limited progress on difficult tasks or an AI bust leaves modest productivity gains that later fade. These are risks he identified, not predictions; he also noted that many large companies making current investments are highly profitable, unlike many firms in the earlier boom. Federal Reserve Board: Barr’s February 17, 2026 speech.

What to watch instead of trying to call a crash
The useful question is whether spending turns into durable returns. These indicators help distinguish a productive buildout from capacity that has run ahead of its use:
- Utilization and demand: Are AI services and data-center capacity being used enough to support the investment?
- Power and delivery: Can electricity supply and distribution keep pace with planned infrastructure?
- Integration: Are firms changing workflows so task-level gains translate into more output, rather than being absorbed by adjustment costs or bottlenecks?
- Earnings: Do companies’ realized results support the expectations embedded in their valuations?
- Returns on investment: Does the buildout generate durable economic value and returns that justify its cost?
None of these measures alone predicts a crash. The comparison is most useful as a reminder that transformative technology, rising investment and financial excess can appear together—and that only realized demand and returns show whether the investment was justified.
