Are We in an AI Bubble? Why This Time Might Be Different

Artificial intelligence (AI) has been one of the biggest drivers of market enthusiasm over the past two years. With share markets — especially in the US — hitting record highs, many investors are asking the same question: Are we in another tech-style bubble?

What’s Fueling the Bubble Talk

• AMP Chief Economist Shane Oliver highlights several warning signs that have raised eyebrows:
• Strong market gains: The US market is up 35% since mid-2022, with global and Australian shares also delivering double-digit annual returns.
• High valuations: The US forward price-to-earnings (PE) ratio sits around 23.6 times — not far from the 1999–2000 tech boom peak of 26 times.
• Narrow market leadership: The Magnificent Seven (Apple, Microsoft, Alphabet, Amazon, Nvidia, Meta, and Tesla) have driven more than half of the S&P 500’s gains since 2023, leaving markets vulnerable if those stocks stumble.
• AI hype vs. reality: Many companies are still in the experimental phase with AI. While the technology is promising, the financial payoff isn’t yet clear.
• Speculative signs: Gold and Bitcoin have also surged, suggesting some investors are leaning into “risk-on” behaviour.

Why This Time Might Be Different

While these factors sound bubble-like, several fundamental differences set today apart from the late 1990s:

1. Real Profits, Not Just Promises

   • The dot-com boom was fuelled by unprofitable companies with sky-high valuations.
   • Today’s tech leaders are highly profitable — the Magnificent Seven have grown earnings by around 30% year-on-year, with the broader US tech sector growing at 17%.

2. Lower Interest Rates Improve Valuations

   • While share valuations are elevated, bond yields remain far lower than in 2000 (then above 6%). This means the equity risk premium — the extra return investors earn over bonds — is still healthier than it was back then.
   

3. AI’s Tangible Productivity Potential

   • Unlike past tech fads, AI is already showing clear use cases — from automation and data analysis to productivity gains across industries.
   • The rise of large language models requires massive investment in data centres, chips, and energy — creating a real-world economic multiplier effect.

4. Economic Backdrop Still Solid

   • Global business surveys (PMIs) show steady, if slowing, growth — no signs yet of an imminent recession.
   

5. Investor Sentiment Not Yet Euphoric

   • Sentiment indicators suggest optimism, but not mania. Interestingly, rising Google searches for “AI bubble” could be a contrarian signal — when investors start worrying about a bubble, it often means we’re not in one yet.

What Investors Should Watch For

Even if fundamentals are stronger this time, investors should remain alert:

• Concentration risk: A small number of tech stocks dominate performance. Diversifying across sectors and regions remains crucial.

• Valuation risk: If earnings disappoint or interest rates rise, high-priced stocks could correct sharply.

• Speculative spillover: Keep an eye on Bitcoin, gold, and other speculative assets — they can indicate when excess enthusiasm starts to spill into broader markets.

The Takeaway

Yes, AI enthusiasm may have run ahead of itself in the short term, but unlike the dot-com era, this boom has real profits, real applications, and a stronger economic foundation.

The lesson?

Don’t try to time the next correction. Even if shares pull back, history shows that markets reward patience. The key is to stick with a well-diversified, long-term investment strategy aligned with your goals and risk tolerance.
