AI Stocks Decline Amid Debt and Spending Concerns on Wall Street
AI stocks decline as debt and spending concerns impact Wall Street, with major indices slightly down and hyperscalers facing scrutiny.
Debt Worries Drag Down AI Stocks Amid Surging Spending Concerns
AI-related stocks faced renewed pressure as investor fears over escalating debt levels and massive capital expenditures rattled Wall Street, contributing to a slight decline in major indices like the S&P 500. On December 12, 2025, tech-heavy benchmarks tumbled, with chipmakers and hyperscalers leading the sell-off, while broader market jitters over bond yields and AI investment sustainability amplified the downturn.
Market Sell-Off Highlights AI Vulnerabilities
The S&P 500 closed marginally lower, weighed down by prominent AI plays. Key decliners included Microsoft (MSFT) and Nvidia (NVDA), both down approximately 10% from their October 29 peaks, alongside Oracle (ORCL) plunging 30% and infrastructure provider CoreWeave dropping 40%, pushing some into bear market territory. This marked the Nasdaq's biggest two-day drop in two months, with big tech names like Broadcom (AVGO) also under fire as analysts urged a rethink of overhyped AI valuations.
Debt concerns stem from the hyperscalers' aggressive AI buildout. Consensus estimates peg 2025 capital expenditures (capex) from Alphabet (GOOGL), Amazon (AMZN), Meta (META), Microsoft (MSFT), and Oracle (ORCL) at around $400 billion, a figure still accelerating despite early signs of strain. Rising bond yields exacerbated the pain, climbing alongside the retreat in chip stocks, signaling investor worries that ballooning debt could undermine profitability if AI returns disappoint.

Contrasting Performance Among AI Players
Despite the broad downdraft, not all AI stocks suffered equally. Year-to-date through December 15, 2025, standout performers included Seagate Technology Holdings (STX), up 188.98% over the past year with a "buy" rating and trading at $284.33 against a $295.23 fair value target. Palantir Technologies (PLTR) followed with a 154.18% one-year gain, market cap of $439.28 billion, and a "hold" rating at $184.30.
Micron Technology (MU) posted 132.83% growth, earning a "strong buy" with a $267.31 target versus $237.62 current price. Symbotic (SYM), specializing in AI-powered warehouse robotics for clients like Walmart and Target, rose 124.85% to $59.99. Nvidia rounded out top performers at 101.69%, with a $753.40 target on a $682.12 price, reflecting its dominant position despite recent pullbacks.
| Top-Performing AI Stocks (as of Dec 15, 2025) | Market Cap | 1-Year Performance | Analyst Rating | Current Price | Target Price |
|---|---|---|---|---|---|
| Seagate Technology (STX) | N/A | 188.98% | Buy | $284.33 | $295.23 |
| Palantir (PLTR) | $439.28B | 154.18% | Hold | $184.30 | $189.40 |
| Micron (MU) | $267.40B | 132.83% | Strong Buy | $237.62 | $267.31 |
| Symbotic (SYM) | $35.89B | 124.85% | Hold | $59.99 | $61.12 |
| Nvidia (NVDA) | $230.53B? | 101.69% | Buy | $682.12 | $753.40 |
This table underscores a bifurcated market: infrastructure and data specialists thrive, while pure-play hyperscalers grapple with capex scrutiny.

Underlying Drivers: Capex Boom Meets Debt Reality
The AI capex cycle remains a powerhouse, fueling optimism for 2026 stock gains alongside policy tailwinds. Analysts project S&P 500 earnings per share (EPS) at $325, potentially driving the index to 7,800 (13% upside) if AI delivers productivity boosts, though they assign only 25% odds to this scenario. A downside case, with 15% probability, eyes 6,200-6,300 if AI falters amid recession fears.
Market breadth has narrowed, with gains concentrated in large-cap growth names, raising durability questions. Risks include AI "bubbles" where sentiment outpaces free cash flow, sudden interest rate spikes, and geopolitical tensions. Jeremy Siegel highlighted "AI jitters," noting benchmark yields' rise coincided with the tech rout.
Smaller AI-linked firms like Workday, Qualys, RingCentral, Sprout Social, and DigitalOcean also fell sharply, amplifying sector-wide pain. Fresh Wall Street concerns focus on whether hyperscalers can justify spending without proportional revenue ramps.
Broader Implications and 2026 Outlook
This sell-off signals a maturing AI narrative: explosive growth meets fiscal accountability. While top performers like Seagate and Micron benefit from data storage and memory demands, hyperscalers face scrutiny over debt-fueled data center expansions. LPL Research emphasizes the cycle's momentum but cautions on overconcentration.
Investors now weigh productivity gains against costs. If AI hyperscalers monetize effectively, 2026 could see robust rebounds; otherwise, prolonged volatility looms, especially in a midterm election year prone to swings. Momentum stocks have outperformed low-momentum peers by 10% since September, with value stocks awakening recently.
The episode underscores AI's dual edge: transformative potential shadowed by trillion-dollar bets. As bond yields stabilize around 3.25-3.5% neutral levels, one-to-two Fed hikes could recalibrate sentiment. JPMorgan upgrades signal banking on economic resilience, but the market's narrow rally demands broader participation for sustainability.

In summary, debt worries have tempered AI euphoria, but resilient performers and ongoing capex suggest the sector's story is far from over. Wall Street watches for earnings clarity to separate winners from overextended bets.
