Tesla and Alphabet plunge as AI spending fears wipe out ~$500 billion
Tesla and Alphabet plunged after signaling higher AI spending, erasing ~$500 billion and rattling the bonds of the biggest tech borrowers.
In Brief
- Tesla closed down 14.52 percent and Alphabet fell 6.89 percent, together erasing roughly $500 billion in market value after both signaled higher AI spending.
- The Nasdaq 100 dropped nearly 2 percent as the Magnificent Seven posted their biggest one-day decline since April 2025, while tech bonds sold off on AI debt fears.
- Investors pulled $7.1 billion from US high-grade bond funds in a week — the most since April 2020 — as oil above $100 a barrel added an inflation shock to the AI capex anxiety.
Wall Street delivered its sharpest rebuke yet to the AI spending boom. Tesla stock closed down 14.52 percent and Alphabet fell 6.89 percent on Thursday after both companies signaled increased spending and reported negative free cash flow for the second quarter, wiping out roughly $200 billion and $300 billion in market value respectively, according to CNBC. Nvidia was dragged down too, losing 4.6 percent and about $120 billion in market cap.
The selloff was not confined to equities. Bonds of the biggest US tech companies slid as renewed worries about the scale of the debt-fueled AI boom collided with escalating conflict in the Middle East, Bloomberg reported. With oil surging past $100 a barrel, longer-term yields climbed, threatening to raise borrowing costs for companies piling hundreds of billions into AI infrastructure.
“The market is being hit with a triple whammy of AI capex anxiety, oil shock and a rate repricing,” Tony Trzcinka, portfolio manager at Impax Asset Management, told Bloomberg. The Nasdaq 100 dropped nearly 2 percent, and the so-called Magnificent Seven suffered their biggest one-day drop since the tariff tantrum of April 2025.
Tesla and Alphabet’s Earnings Spooked Two Markets at Once
Alphabet’s quarter was the catalyst. The company raised its capital expenditure forecast to $195 billion to $205 billion for the year — up from $180 billion to $190 billion — and warned of higher figures in 2027, per CNBC. Its CFO said the increase “is primarily due to an acceleration in the delivery of capacity to meet growing demand.” The bond market’s response: yields on Alphabet’s 5.5 percent bonds due 2046 jumped about 9 basis points to 6.11 percent, Bloomberg reported.
Tesla’s numbers cut deeper. Elon Musk leaned into the spending: “This is a massive capex year. I’m confident that all the things that we’re investing in will yield incredible returns. Really, maybe the best capex returns that we’ve ever seen,” he said on the earnings call, per CNBC, touting semiconductor production and the Optimus humanoid robot as Tesla installs “the first-generation lines” for the robot.
There were genuine bright spots — Google Cloud revenue jumped 82 percent to $24.8 billion, and Tesla’s automotive revenue rose 23 percent to $20.52 billion, per CNBC — but investors fixated on the cash burn. “Investors appear to be focusing on the sharp rise in capital expenditure, alongside a weaker margin outlook,” Ben Barringer of Quilter Cheviot told CNBC.
AI Debt Fears Spread Through the Credit Market
The credit stress is broadening. Investors yanked $7.1 billion from US high-grade bond funds in the week ended Wednesday — the most since April 2020, in the early days of the pandemic — according to LSEG Lipper data cited by Bloomberg. AI-related borrowing has totaled some $350 billion this year alone.
“Tech used to be where investors hid and now hyperscalers are on pace to rival the Big Six banks as the top issuers in investment-grade,” Mark Clegg, senior fixed-income trader at Allspring Global Investments, told Bloomberg. “Even the whisper of another $20 billion deal and the whole complex reprices wider. This is supply fatigue, and it’s accelerating week by week.”
More supply is coming: BlackRock is looking to sell over $12 billion of bonds to finance a Meta data center in El Paso, and Barclays raised its 2026 US high-grade issuance forecast to $1.9 trillion from $1.6 trillion, per Bloomberg. The episode extends the pattern Frontierbeat flagged when investors began dumping Big Tech over unjustified AI spending — and it hammered chip stocks already flirting with bear-market territory.

Why did higher capex trigger such a violent reaction?

Record outflows of $7.1 billion from high-grade funds in a week, widening spreads on Alphabet debt, and roughly $350 billion in AI-related borrowing this year with more supply in the pipeline.
