Palantir stock chart showing decline amid AI bubble and hidden debt concerns
Palantir slides nearly 5% as AI bubble warnings and a $1.65 trillion hidden-debt overhang rattle the sector.

After a brief rebound early this week, AI stocks are back under pressure. Fears of a bubble and a massive hidden-debt pile at Big Tech are weighing on the sector. As of 12:30 p.m. ET Tuesday, Palantir (PLTR) was trading sharply lower.

  • PLTR intraday: At 12:30 p.m. ET, shares were at $126.44, down 4.69% (-$6.22) from Friday's close of $132.66. The session low hit $125.83.
  • AI sector rebound: On Monday, the S&P 500 rose 0.9% and the Nasdaq Composite gained 1.3%, led by AI names. Micron Technology surged 12.2%, and Nvidia added 2%.[Los Angeles Times]
  • AI bubble warning: The Atlantic notes that the market cap of AI-related companies has surged $27 trillion over the past three years — equal to 36% of the entire U.S. stock market. OpenAI CEO Sam Altman has publicly said, "We are in an AI bubble."[The Atlantic]
  • Trillion-dollar hidden debt: Per Nikkei, off-balance-sheet debt at Alphabet, Amazon, Meta, Microsoft, and Oracle has ballooned to $1.65 trillion — an eightfold increase in four years — largely to fund data-center buildouts. Morgan Stanley and Moody's have flagged the risk.[Semafor]
  • Macro backdrop: Brent crude briefly topped $91 a barrel, and the 10-year Treasury yield rose to 4.63%, reigniting inflation fears that could influence the Fed's next moves.[Los Angeles Times]

As of 12:30 p.m. ET Tuesday, Palantir (PLTR) was trading at $126.44, down 4.69% from Friday's close of $132.66, with an intraday low of $125.83. The stock failed to extend Monday's AI sector rebound, as lingering fears over an AI bubble and massive off-balance-sheet debt at tech giants weighed on sentiment.

AI Rebound Fizzles? PLTR Bucks the Trend

Monday saw a strong bounce in AI stocks. According to the Los Angeles Times, the S&P 500 rose 0.9% and the Nasdaq Composite gained 1.3%, led by AI names. Micron Technology surged 12.2%, and Nvidia added 2%, together providing the biggest boost to the S&P 500.[Los Angeles Times]

Barron's noted that the "AI trade" appeared to be back on Monday, as Wall Street briefly shook off concerns that a cheap Chinese chatbot could end the chip and memory spending boom.[Barron's]

But the rally didn't stick. PLTR dropped nearly 5% on Tuesday, making it one of the weaker names in the AI cohort. Market participants see this as a sign that deep-seated worries about AI valuations and profitability haven't gone away.

AI Bubble Warning: $27 Trillion in Market Cap and 'Optimistic' Expectations

The Atlantic published a deep-dive titled "The AI Bubble Is No Ordinary Bubble," delivering a stark warning on the current AI frenzy. It notes that the market cap of AI-related companies has surged $27 trillion over the past three years — equal to 36% of the entire U.S. stock market.[The Atlantic]

Citing Goldman Sachs strategists Dominic Wilson and Vickie Chang, the article says that while future earnings "could" justify current valuations, profit expectations require "extreme optimism" to be realized. OpenAI CEO Sam Altman has publicly said, "We are in an AI bubble." The IMF has flagged it as a major risk to financial stability, warning of potential fallout: reduced investment, tighter credit, lower consumption, and disrupted trade flows.[The Atlantic]

Still, the article notes this bubble is different from past ones: it's driven by ultra-wealthy corporations rather than retail investors, and it's occurring in a period of relatively high credit costs. That could make it "less fragile and longer-lasting," but "no less painful when it bursts."[The Atlantic]

Trillion-Dollar Hidden Debt: Big Tech's Off-Balance-Sheet Risk

Semafor reports that concerns are mounting over the "off-balance-sheet debt" of AI giants. According to Nikkei, financial statements from Alphabet, Amazon, Meta, Microsoft, and Oracle show their hidden debt has surged to $1.65 trillion — an eightfold increase in four years — largely to fund a data-center building spree.[Semafor]

While these companies expect future earnings to outpace the debt, the market "has begun to show concern." Morgan Stanley and Moody's have both highlighted the issue in their reports.[Semafor]

A Reuters commentary takes a different angle, arguing that "AI has not killed equity diversification." Despite the AI theme dominating markets, investors should still focus on a diversified portfolio.[Reuters]

Macro Headwinds Mount: Oil Breaks $91, Treasury Yields Climb

Beyond AI-specific concerns, the macro environment is adding pressure. Per the Los Angeles Times, Brent crude briefly neared $92 a barrel on Monday — a five-week high — before settling at $91.01. The rally stems from ongoing U.S.-Iran tensions, with oil surging from under $72 at the start of the month to near pre-Iran-war levels.[Los Angeles Times]

Rising oil prices threaten to reignite inflation, which had been cooling faster than economists expected. That could push the Federal Reserve and other central banks to hike rates, slowing growth and weighing on stocks and other assets. The 10-year Treasury yield has climbed from 3.97% before the Iran conflict to 4.63% on Monday.[Los Angeles Times]

Despite these headwinds, better-than-expected earnings from several large U.S. companies helped lift the market on Monday. 3M rose 7.3% after beating on both profit and revenue.[Los Angeles Times]
