in the AI Investment Frenzy
How AI hype is fueling a risky corporate debt buildup reminiscent of the 1990s tech bubble
The AI boom is dazzling investors with skyrocketing stocks and eye-popping deals. But beneath the shiny surface, troubling signs hide in plain sight. This article breaks down how massive corporate debt, weak short-term AI returns, and parallels to the late-1990s tech bubble raise red flags for today’s AI investing climate. Learn why understanding these hidden risks can safeguard your portfolio before the music stops.
Why Is Everyone Going All In on AI — And Should Investors Worry?
Earlier in 2025, OpenAI inked a staggering $300 billion deal with Oracle, sending Oracle shares rocketing 50%. Oracle then leveraged its surge to snap up Nvidia hardware, which in turn propelled Nvidia stock to fresh all-time highs. Nvidia responded by committing $100 billion back into its OpenAI partnership. This whirlwind is pushing massive amounts of capital in a loop revolving mainly around Nvidia — the AI darling of Wall Street.
Some cynics call it a Ponzi scheme, but isn’t it only a Ponzi if there’s no real value? Well, according to a recent MIT study, 95% of corporate investments in generative AI have delivered zero return on investment so far. That calls the sustainability of this frenzy into serious question.
The Productivity Puzzle
The same study shows about 40% of businesses use AI large language models for simple tasks — drafting emails, summarizing texts, note-taking. Also, a “shadow AI economy” has bloomed, where employees use consumer AI tools to boost individual productivity.
That sounds promising at the individual level. Yet, the billions of dollars are meant to help businesses slash labor costs and optimize operations — not just help workers type faster. The big question: Does this individual productivity bump translate into real corporate profits? If not, the huge capital inflows into AI investments might be unjustified.
Sky-High Corporate Debt
This enthusiasm has a darker side: the way it’s financed. Companies across tech giants are borrowing heavily:
- Google ramped up $10 billion in debt in 2025 alone
- Meta’s debt hit $28 billion since 2022
- Microsoft’s debt jumped from $27 billion to $46 billion over the past year
- Oracle is carrying nearly $90 billion in debt and increasing it quarterly
In total, US tech firms issued about $157 billion in bonds in 2025 — a 70% increase from last year. JP Morgan estimates AI-related debt now makes up 14% of the entire corporate debt market.
Debt isn’t just free money — it must be paid back with interest. Companies banking on AI to create new revenues need returns to justify this risk. The problem: short-term ROI on AI investments remains highly questionable at best.
History Repeats? Lessons From the 1990s Tech Bubble
This high-stakes game feels hauntingly familiar. In the late 1990s, internet stocks soared as companies poured billions into web infrastructure. The NASDAQ 100 was melting up, driven by giants like IBM, AT&T, Cisco, Walmart, Intel, GE, and Microsoft.
Warnings rang out from experts and academics:
- Stanford noted the tech sector’s growth was causing structural economic imbalances
- Nobel laureate Robert Shiller cautioned about speculative excesses
Despite forewarnings in 1996–1997, investors kept bidding internet stocks higher. The peak didn’t arrive until March 2000—three years later—toppling the NASDAQ 100 by 80% and bankrupting many over-leveraged tech firms.
The takeaway? Markets can remain irrational longer than you can stay solvent. Early investors profited for years but many who joined late lost everything.
What Might Trigger the AI Bubble to Burst?
The 1999 tech crash was triggered by the Federal Reserve raising interest rates to cool overheated markets. Currently, we see a similar pattern:
- Semiconductor-focused ETFs, strongly tied to AI stocks, are in a parabolic run
- The Fed has been lowering interest rates recently, fueling speculation
- When rates begin rising, the frothy market may unravel rapidly
As long as borrowing stays cheap, speculative bets on AI will likely continue. But once the Fed tightens, companies burdened with AI debt but lacking profitable returns may face defaults and crashing valuations.
Data Callout: AI-Driven Corporate Debt Growth
In 2025, US tech firms issued $157 billion in new bonds, a 70% surge from 2024. JP Morgan reports that AI-related debt now accounts for 14% of the entire US corporate debt market, underscoring the scale of risk woven into this seemingly unstoppable rally.
Risks and What Could Go Wrong
- High Debt Loads: Companies accumulating massive AI-related debt must produce profits to pay interest and principal. Failure could lead to defaults and credit events, dragging down stocks.
- Questionable ROI: With 95% of generative AI investments reportedly yielding no returns so far, the economic benefit may lag far behind valuations.
- Regulatory or Ethical Fallout: Emerging AI use cases, such as in adult content or controversial applications, could invite backlash or regulation, hitting companies unexpectedly.
- Interest Rate Hikes: Rising rates could choke off cheap borrowing, exposing debt risks and triggering sell-offs reminiscent of the dot-com bust.
- Market Sentiment Shifts: Investor enthusiasm can evaporate quickly if growth disappoints, leading to steep price corrections.
Actionable Summary
- AI investment hype is driving massive corporate debt issuance, particularly among tech giants like Oracle, Nvidia, Google, Meta, and Microsoft.
- Short-term returns on AI projects remain poor; most generative AI investments show zero ROI according to MIT research.
- The current cycle closely resembles the late 1990s tech bubble, which ended in an 80% peak-to-trough NASDAQ 100 collapse.
- Federal Reserve policies, especially interest rates, will be a key trigger for whether the AI boom continues or bursts.
- Investors should watch debt levels, earnings reports, and Fed moves to gauge risk and position accordingly.

Frequently Asked Questions (FAQs)
Q1: Why are AI stocks rallying despite low short-term returns?
AI hype fuels investor optimism, low interest rates enable cheap borrowing, and tech firms reinvest heavily hoping for long-term gains. This creates a feedback loop that drives prices higher, even without immediate profits.
Q2: What does 95% of AI investments producing zero ROI mean?
It means most corporate AI projects have yet to deliver measurable financial returns, suggesting the technology’s business impact is still developing or uncertain in the short term.
Q3: Should investors be worried about corporate debt related to AI?
Yes. High debt levels increase financial risk, especially if AI investments fail to generate expected profits, leaving companies vulnerable to defaults when debt matures.
Q4: How similar is today’s AI boom to the 1990s tech bubble?
Both involve massive speculative investment, rapid stock price increases, and heavy corporate spending amid uncertain profits, all before rising interest rates cooled the market.
Q5: What signals should investors watch for to identify a market peak?
Monitor Federal Reserve interest rate changes, corporate earnings on AI projects, debt issuance trends, and shifts in investor sentiment as key indicators of a potential bubble peak.
