An estimated $1.3 trillion has been wiped from global markets as investors suddenly reassess the extraordinary valuations attached to artificial intelligence. In her latest World Affairs In Context podcast, Lena Petrova argues that the AI boom is entering a critical new phase as markets begin asking tougher questions about profits, valuations and economic reality.
ELOCAL REPORT
For almost three years, artificial intelligence has been the hottest investment theme on the planet.
Since the launch of ChatGPT in late 2022, investors have poured money into semiconductor companies, cloud computing firms, data centre operators and virtually any business with a connection to artificial intelligence.
The logic was straightforward.
AI was expected to transform healthcare, finance, manufacturing, transportation, defence, logistics and countless other industries. Investors rushed to secure positions in what many believed would become the defining technology revolution of the twenty-first century.
Now, according to Lena Petrova, markets are experiencing their first major reality check.
$1.3 Trillion Disappears
Petrova points to a sudden global sell-off that erased approximately $1.3 trillion in market value.
The trigger was a stronger-than-expected US employment report which forced investors to rethink expectations surrounding Federal Reserve interest rates.
Instead of anticipating lower rates, markets began pricing in the possibility that rates could remain higher for longer.
That matters enormously for technology stocks.
Many AI companies derive their valuations from earnings expected years into the future. Higher interest rates reduce the present value of those future earnings, causing investors to reassess what they are willing to pay today.
The result was a rapid sell-off across technology markets.
Semiconductor Stocks Hammered
According to Petrova, semiconductor companies were among the hardest hit.
The Philadelphia Semiconductor Index fell approximately 10 percent as investors questioned whether AI-related valuations had become excessive.
For many market participants, the correction served as a reminder that even revolutionary technologies can become overvalued when investor enthusiasm outruns financial reality.
South Korea Suffers One Of Its Worst Sell-Offs
One of the most dramatic market reactions occurred in South Korea.
The country's benchmark KOSPI Index plunged more than 8 percent in a single session, triggering market circuit breakers and temporarily halting trading.
Major technology companies suffered heavy losses.
Samsung Electronics fell more than 10 percent.
SK Hynix, one of the world's most important suppliers of advanced AI memory chips, also recorded substantial declines.
Petrova notes that South Korea sits at the centre of the global AI supply chain, making it particularly vulnerable when sentiment turns against technology stocks.
The AI Boom Meets Economic Reality
Petrova argues that what investors are now witnessing follows a familiar historical pattern.
Railways.
Electricity.
The internet.
Each technological revolution transformed society.
Each also experienced periods of speculative excess where investors became convinced that future profits would justify almost any valuation.
Artificial intelligence may now be encountering the same challenge.
Three Major Warning Signs
Petrova identifies several developments that have fuelled growing anxiety.
Valuations Have Run Far Ahead Of Earnings
Many AI-linked companies have experienced stock price growth that bears little resemblance to actual profit growth.
Investors have been pricing in years of uninterrupted expansion and near-perfect execution.
Market Gains Became Increasingly Concentrated
A relatively small number of technology companies generated much of the market's recent gains.
When investor sentiment shifted, those same stocks became vulnerable to rapid declines.
Massive Spending Requires Massive Returns
Technology companies have invested hundreds of billions of dollars in:
- Data centres
- Semiconductor manufacturing
- Computing infrastructure
- AI development platforms
Petrova notes that investors are increasingly demanding evidence that these investments can generate profits large enough to justify the extraordinary spending.
Demand Remains Strong
Despite the sell-off, Petrova stresses that the AI revolution itself is far from over.
Demand for computing power remains enormous.
Data centres continue to be built around the world.
Technology giants remain locked in intense competition to develop more advanced AI systems.
Semiconductor shortages continue to affect portions of the supply chain, reflecting the strength of underlying demand.
The technology remains transformative.
What has changed is investor psychology.
Blind Optimism Is Fading
Petrova believes the market is moving beyond the phase where simply mentioning artificial intelligence was enough to attract investment.
Investors are becoming more selective.
The questions now being asked are no longer about whether AI will change the world.
The questions are:
- Can AI generate enough profits to justify current valuations?
- Can technology companies maintain their explosive growth rates?
- Have investors become too optimistic about how quickly commercial adoption will occur?
These questions are increasingly shaping market behaviour.
Federal Reserve Still Holds The Keys
Petrova believes inflation data and Federal Reserve policy will play a major role in determining what happens next.
If inflation remains elevated and interest rates stay high, technology stocks could face additional pressure.
If AI companies continue producing strong earnings and demonstrate clear returns on investment, confidence could recover rapidly.
A New Chapter For Artificial Intelligence
Petrova argues that the AI revolution is not ending.
Instead, it is entering a new stage.
The era of speculative enthusiasm is giving way to a period where profitability, cash flow and economic performance matter far more than promises.
Artificial intelligence remains one of the most important technological developments of modern times.
The debate now centres on whether markets have correctly priced its future.
Conclusion
For nearly three years, artificial intelligence has driven one of the largest investment booms in modern financial history.
The latest correction suggests investors are finally beginning to scrutinise the assumptions underpinning that boom.
Whether this proves to be a temporary correction or the beginning of a larger market adjustment will depend on how quickly AI companies can convert enormous investment spending into sustainable profits.
According to Lena Petrova, the AI story is far from finished.
But the easy money phase may be over.
