Trump Iran Threat Erases Nearly $1 Trillion From Big Tech

U.S. stocks recorded their worst daily decline in a month on July 23. Oil crossed $100 as the conflict involving Iran widened.

The S&P 500 fell 1.2% to 7,408.30, Associated Press data showed. The Nasdaq Composite lost 2.2%, while the Dow Jones Industrial Average dropped 1%.

The Magnificent Seven companies lost about $938.7 billion in combined market capitalization. MarketWatch described it as their second-largest one-day loss on record.

President Donald Trump added to market concerns by threatening further attacks against Iranian infrastructure.

Trump said the U.S. would destroy bridges or power plants after attacks on vessels. His comments also raised the possibility of targeting infrastructure near Tehran.

US Stocks Fall as Oil Crosses $100

Brent crude climbed 7% to $100.71 during July 23 trading. It crossed $100 for the first time since late May.

West Texas Intermediate crude rose 6% to $92.01. Both contracts extended their gains for a fifth consecutive session.

The rise followed reported attacks against two Saudi oil tankers. Yemen’s Iran-aligned Houthis claimed responsibility for the strikes.

The group identified the vessels as Encelia and Layla. A maritime security source said a missile struck Encelia near Saudi Arabia’s Jizan port.

The Houthis had announced a naval blockade on Saudi shipments. Their attacks raised concerns about disruption near the Bab el-Mandeb Strait.

The route became more important after the disruption around the Strait of Hormuz. Saudi Arabia had redirected some crude shipments through the Red Sea.

The Bab el-Mandeb route handled about 2.5 million barrels of Saudi oil daily. Ships avoiding the area would face longer routes around southern Africa.

Higher transport and insurance costs could place further pressure on energy prices. Rising oil prices also increased concerns about renewed U.S. inflation.

Treasury yields climbed as traders reconsidered expectations for lower interest rates. Higher yields added pressure across technology stocks and crypto assets.

Big Tech Losses Drive US Stocks Lower

The Magnificent Seven group comprises Alphabet, Amazon, Apple, Meta Platforms, Microsoft, Nvidia and Tesla. The group’s $938.7 billion loss approached $1 trillion.

Tesla shares fell about 14%, while Alphabet lost nearly 7%. Both companies faced investor concerns about artificial intelligence spending.

Other major technology stocks also declined. Consumer discretionary, communication services and technology ranked among the weakest S&P 500 sectors.

The sell-off showed investors were becoming less tolerant of rising capital expenditure. Companies now face pressure to show faster returns from artificial intelligence projects.

Alphabet Cash Burn Raises AI Spending Concerns

Alphabet reported negative free cash flow of $5.9 billion during the second quarter.

The result marked the Google parent’s first recorded cash burn. Its cloud revenue still increased 82% from the previous year.

Alphabet raised its 2026 capital expenditure forecast to between $195 billion and $205 billion. The company had previously projected spending of about $190 billion.

Second-quarter capital expenditure reached approximately $45 billion. Much of that spending supported data centers and artificial intelligence infrastructure.

Strong revenue growth failed to offset investor concerns about cash generation. Alphabet shares fell as traders questioned the timing of returns.

Chief Financial Officer Anat Ashkenazi also warned that 2027 spending would rise further. That outlook increased concerns about pressure on future profit margins.

Tesla Reports First Cash Burn in Two Years

Tesla reported negative free cash flow of $1.1 billion during the second quarter.

It marked the electric vehicle company’s first quarterly cash burn in over two years. Tesla accelerated spending on artificial intelligence, batteries, robotaxis and manufacturing.

Capital expenditure rose 142% from the previous year to $5.8 billion. Tesla expected annual artificial intelligence investment to exceed $25 billion.

Chief Executive Officer Elon Musk defended the spending during the company’s earnings call. He said Tesla should expand artificial intelligence investment rapidly.

However, investors focused on weaker cash flow and missed profit expectations. Tesla’s 14% decline added heavily to the wider technology sell-off.

Crypto Market Falls With US Stocks

Bitcoin also fell as traders reduced exposure to higher-risk assets.

The cryptocurrency declined toward $64,000 during the wider market sell-off. Ether, Solana and XRP recorded steeper percentage losses.

Higher Treasury yields reduced demand for assets that produce no interest income. Oil-driven inflation concerns also weakened expectations for monetary easing.

However, Trump’s statement did not cause every market decline alone. Big Tech earnings and artificial intelligence spending concerns played major roles.

US Stocks Face Several Market Pressures

The July 23 decline reflected geopolitical, energy and corporate pressures.

Trump’s Iran threat raised fears of further military escalation. Houthi tanker attacks created risks near another major oil transit route.

Alphabet and Tesla then intensified the sell-off through weaker cash-flow results. Their declines raised wider questions about returns from artificial intelligence spending.

The Magnificent Seven lost $938.7 billion during the session. That verified figure supports describing the loss as nearly $1 trillion.
