AI Spending Fears Hit Tech Stocks

The latest market pullback is exposing a tougher question for the artificial intelligence boom: how quickly can enormous investments in computing infrastructure translate into sustainable cash flow and returns for shareholders?

The pressure was visible across US markets on Thursday, 22 October, when the Nasdaq Composite fell 2.6% in its steepest daily decline since early June. The Philadelphia Semiconductor Index dropped 6.7%, while the S&P 500 lost approximately 1.2%. The Dow Jones Industrial Average proved more resilient, edging slightly higher.

At the same time, gold was heading toward its steepest weekly decline in more than four months. Spot prices fell to around $4,016 per ounce early on Friday, 23 October, down approximately 3.5% for the week. Rising oil prices were reviving inflation concerns and complicating expectations for interest-rate cuts.

Together, the two moves reveal a market reassessing both the cost of future growth and the interest-rate environment in which that growth must be financed.

AI Spending Becomes the Central Question

The sell-off followed a fresh round of corporate earnings that shifted attention away from AI’s long-term potential and toward the immediate financial burden of building it.

Meta Platforms reported quarterly revenue above expectations, but its shares fell 7% as investors focused on rising infrastructure commitments and plans to issue non-voting shares to help finance its expansion. The company raised the lower end of its 2026 capital expenditure outlook to $135 billion, leaving the upper end at $145 billion. It also reported negative free cash flow of $2.12 billion for the quarter, compared with positive free cash flow of $10.63 billion a year earlier.

The numbers illustrate the scale of the investment cycle. AI infrastructure requires data centres, advanced processors, networking equipment, energy capacity and long-term financing. These costs are incurred before the full commercial value of new AI products and services is necessarily visible in reported earnings.

For investors, the distinction between revenue growth and profitable growth is becoming increasingly important. Strong demand for AI services can support a company’s sales, but the financial outcome depends on the cost of delivering those services, the useful life of its infrastructure and the extent to which customers are willing to pay for increasingly capable models.

Semiconductor Stocks Under Pressure

The weakness extended beyond individual technology companies. The Philadelphia Semiconductor Index fell 6.7%, its largest daily percentage decline since 23 June, reflecting the market’s sensitivity to changes in expectations for AI-related investment.

Chipmakers have benefited from demand for the processors required to train and operate AI systems. Their valuations, however, also depend on expectations that current demand will persist and that customers’ infrastructure spending will continue to expand.

A reassessment of capital expenditure can therefore affect several layers of the industry simultaneously: chip designers, semiconductor equipment manufacturers, data-centre operators and businesses providing cloud computing capacity.

The pressure was not limited to semiconductor stocks. Tesla fell 3.1% on Thursday, while the broader technology sell-off contributed to declines in major US equity indices. US Treasury prices rose as investors sought relative safety, pushing yields lower.

Gold Faces a Different Challenge

Gold’s decline over the same period reflects a separate but connected concern: the possibility that inflation will remain persistent enough to delay monetary easing.

Spot gold traded around $4,016.27 per ounce early on Friday, 23 October, after touching its lowest level since 20 July. The metal was down approximately 3.5% for the week, putting it on course for its steepest weekly fall in more than four months.

Oil prices were a major part of the equation. Brent crude rose to a five-month high after attacks on Saudi targets heightened concerns about disruption to energy supplies. More expensive energy can feed into transport, production and consumer prices, potentially making inflation more difficult for central banks to bring under control.

That creates a difficult environment for gold. Although the metal is often viewed as a store of value during periods of uncertainty, it does not pay interest. When markets anticipate higher interest rates for longer, interest-bearing assets can become more competitive, increasing the opportunity cost of holding bullion.

The result is a divergence between traditional safe-haven narratives and short-term market pricing. Geopolitical risk and inflation uncertainty may support demand for gold over time, but near-term interest-rate expectations can still exert substantial downward pressure.

The Federal Reserve in Focus

Investors are looking toward the Federal Reserve’s 27–28 October policy meeting and the next release of the personal consumption expenditures price index, a key measure of US inflation.

Market attention is increasingly focused on whether elevated energy prices will complicate the inflation outlook and limit the central bank’s room to ease policy. Expectations for future rates can influence both equity valuations and the relative attractiveness of gold, even before the Fed announces a decision.

For technology companies, financing conditions matter because AI infrastructure is capital-intensive and often requires investment years before the full return becomes measurable. Higher borrowing costs can make expansion more expensive, while equity issuance can dilute existing shareholders. Companies with strong cash generation may be better positioned to fund investment internally, but even those businesses face scrutiny when spending accelerates faster than near-term cash returns.

Markets Demand Evidence of Returns

The latest moves do not, by themselves, establish that the AI investment cycle is ending. They do show that investors are becoming more selective about how its costs and benefits are distributed.

The next phase of the AI trade may depend less on broad announcements of spending and more on evidence that those investments can generate durable revenue, protect margins and deliver acceptable returns on capital. Companies that can demonstrate those results may be treated differently from those whose growth depends on increasingly expensive infrastructure and continued access to financing.

Meanwhile, the gold market is responding to a separate macroeconomic test: whether energy-driven inflation will keep interest rates elevated for longer than investors had anticipated.

Both developments point to the same underlying market discipline. Growth expectations remain important, but their value depends on the cost of capital, the durability of cash flows and the timing of returns.
