Young investors love AI stocks. Are they falling into a debt trap?

During one trading week, investors wiped more than US$1 trillion from 20 major AI and semiconductor companies. By the following week, many had rebounded, showing the sector’s sharp swings.

The sell-off was a sudden drop in the value of leading technology shares, followed by a quick recovery. It matters because AI companies remain unpredictable, while investors question whether their expensive growth can continue.

CoreWeave shows the pressure behind the volatility. Its debt rose from about US$30 billion last year to US$52 billion by the second quarter. Rising US interest rates make that borrowing more expensive, especially while the company remains unprofitable. Its shares fell 30% in one month, and its valuation dropped to about US$34 billion. The quick rebound did not remove the risks. Analysts still see a strong AI industry but recommend caution because spending may be unsustainable.

An AI stock is a share in one company that develops, supplies, or supports artificial intelligence. Its price depends on that company’s profits, debt, management, and delivery—not simply on AI’s overall promise. Investing in the industry means spreading exposure across many AI-related businesses, often through several shares or a fund.

CoreWeave shows the difference. It operates cloud computing and data centres for companies building AI, and its debt grew from about US$30 billion to US$52 billion. Rising US interest rates made borrowing more expensive, while CoreWeave remained unprofitable. Its shares fell 30 per cent in one month, despite strong enthusiasm for AI.

An industry-wide investment can still fall if AI spending slows or promises disappoint. Deutsche Bank warned current AI spending may be unsustainable, while RBC recommended reducing technology holdings. The practical lesson is that AI’s growth does not guarantee every AI stock will rise; research, diversification, and risk tolerance remain essential.

The sell-off erased more than US$1 trillion from the market value of shares in one week. It hit 20 of the world’s biggest semiconductor and AI companies, showing how quickly this sector can swing.

CoreWeave illustrates the pressure: its shares fell 30% in the month, while its valuation dropped to about US$34 billion. The company relies on debt, which became more expensive as US interest rates and Treasury yields rose.

The decline was dramatic, but many affected shares rebounded during the following week. The episode matters because AI spending remains uncertain, and analysts warn that slowing investment could cause wider economic damage. That rebound did not erase the warning about concentrated risk. For investors, the scale supports researching risks rather than assuming industry growth guarantees returns.

Young investors are drawn by AI’s huge promise and the chance to enter a rapidly growing industry early. They also have decades for their portfolios to recover from setbacks, making potential rewards seem worth the volatility.

The upcoming IPOs of Paradox and Axiom add excitement because investors may soon buy shares in highly visible AI leaders. CoreWeave shows the appeal: its March 2025 IPO was the biggest tech debut since 2021, and its value reached US$90 billion by June.

But these companies are selling future potential, not always proven profits. CoreWeave carried US$30 billion in debt and liabilities last year, rising to US$52 billion by the second quarter, while its shares fell 30 percent this month. The attraction is real, but rising rates and heavy borrowing can quickly turn early enthusiasm into losses.

Heavy borrowing makes an AI company more exposed to rising interest rates because loan payments become more expensive. That can drain cash needed for expansion, especially when the business is not yet profitable.

CoreWeave shows the danger. By its second quarter, CoreWeave’s debt had grown from about US$30 billion to US$52 billion. As US rates and Treasury yields rose, its borrowing became costlier, while weak profits made repayment harder.

CoreWeave shares fell 30 percent in one month, and its valuation dropped to about US$34 billion. Its bond yields also reached levels that generally signal financial distress. Investors should remember that strong AI demand does not guarantee safe returns. If spending slows before promised results arrive, heavily indebted companies could face even greater pressure.

Investors may reduce technology holdings because AI stocks are unusually volatile and many companies depend heavily on borrowing. Rising US interest rates make that debt more expensive, threatening profits and growth.

CoreWeave shows the risk. Its debt grew from about US$30 billion last year to US$52 billion by the second quarter of this year. Its shares fell 30 per cent in one month, while its valuation dropped to about US$34 billion. Higher rates pushed its bond yields toward distress levels, as the company remained unprofitable.

That is why RBC Capital Markets downgraded technology from “overweight” to “market weight”. It suggested safer sectors such as healthcare, whose demand remains steadier because people still need medicine and medical care. This does not mean AI is failing: Deutsche Bank said AI spending is supporting the US economy. However, investors may prefer balance and reduced downside while the sector’s future remains uncertain.

Rising interest rates make company debt more expensive, especially for businesses borrowing heavily to expand. They can also reduce valuations. Investors often pay less for profits expected years ahead when safer assets offer better returns.

CoreWeave shows the risk: its debt grew from about US$30 billion last year to US$52 billion in the second quarter. Higher interest costs squeeze cash, and expensive borrowing makes future growth less attractive. CoreWeave’s shares fell 30 percent in one month, while its valuation dropped from about US$90 billion to US$34 billion.

That pressure is now shaping broader expectations. Deutsche Bank warned last month that current AI spending is unsustainable and could cause economic havoc if it slows prematurely. RBC Capital Markets cut its technology recommendation from “overweight” to “market weight”, favouring safer sectors such as healthcare.
