LONDON: Artificial intelligence is transforming industries and attracting enormous investment worldwide. But as technology companies pour billions into chips, data centres and advanced models, concerns are growing that financial expectations may be rising faster than actual profits.

Recent market turbulence has intensified a central question: Is artificial intelligence creating sustainable economic value, or are investors inflating another technology bubble?

What Is the AI Bubble?

An investment bubble develops when asset prices rise far beyond levels justified by earnings, revenue and realistic expectations of future growth.

In artificial intelligence, investors are betting that the technology will revolutionise businesses, increase productivity and generate substantial profits.

Companies developing AI models, manufacturing semiconductors and building data centres have consequently attracted extraordinary valuations.

However, high valuations become vulnerable when anticipated earnings fail to materialise.

Why Are Companies Spending Billions?

The AI race requires enormous computing power, specialised chips, electricity and infrastructure.

Meta announced plans on Monday to raise up to $95 billion to finance its expansion, despite holding approximately $82 billion in cash and marketable securities.

The company has also projected annual capital expenditure of $135 billion to $145 billion.

Such spending illustrates the financial commitment required to compete in an increasingly expensive industry.

Yet investors are questioning whether future AI revenues can justify these investments.

What Could Trigger a Collapse?

An AI bubble could burst if companies report disappointing profits, demand weakens or investors lose confidence in future returns.

Rising borrowing costs, restrictions on semiconductor exports and excessive competition could accelerate a downturn.

China offers a recent warning. Its technology-heavy STAR50 index has fallen approximately 40 percent from July highs, erasing an estimated $480 billion in market value.

Meanwhile, US technology stocks have also experienced selling pressure, although declines have been considerably smaller.

Would AI Technology Disappear?

A stock market collapse would not necessarily mean artificial intelligence had failed.

The dot-com crash demonstrated that technological innovation can continue even after speculative valuations collapse.

AI already supports software development, healthcare research, customer services and industrial operations.

The critical question is whether companies can turn these applications into sustainable earnings.

Who Would Be Affected?

A sharp correction could hurt shareholders, pension funds, technology start-ups and companies dependent on continued investment.

Expensive infrastructure projects could face delays, while weaker businesses might struggle to secure financing.

Nevertheless, more realistic valuations could redirect capital towards commercially viable applications.

Ultimately, the distinction between AI’s technological potential and its financial valuation will determine whether today’s investment boom produces lasting prosperity or painful market losses.
