Wall Street Opens Lower as AI Stocks Crumble Again

 

Wall Street Opens Lower as AI Stocks Crumble Again—And $110 Oil Is Making Everything Worse

## The Short Version (For the Busy American)

Monday's relief rally didn't even make it to Tuesday afternoon.

U.S. stocks opened lower Tuesday morning as **AI-linked shares resumed their slide** and **Brent crude climbed back above $110 a barrel**. Nasdaq futures fell **0.62%**, S&P 500 futures slipped **0.2%**, while Dow futures managed a small gain—the same defensive rotation that's defined the market for weeks .

The pain was concentrated in the names that got hammered last week. **CoreWeave dropped another 4.7%** in premarket trading. **Nebius fell 4.9%**. Even **Apple and Nvidia** were in the red . The AI trade just can't catch a break.

**The punchline:** This isn't a random selloff. It's a **global repricing of AI risk**, and the trigger came from Tokyo and Seoul overnight. Japan's Nikkei fell **1.3%**, South Korea's KOSPI plunged **3.73%**, and a South Korean data-center IPO lost **a third of its value on day one** . When the AI trade breaks, it breaks everywhere.

## What's Driving Tuesday's Selloff

Let me break down the three forces pushing stocks lower, because they're all connected.

### Force #1: The AI Credit Panic Is Global

The CoreWeave contagion has spread across the Pacific.

In Tokyo, **SoftBank Group's share price plunged more than 6%**, and its five-year credit default swap premium—essentially the cost of insuring against default—surged to **432 basis points**, the highest level in four years . JPMorgan's quantitative strategist Masanari Takada put it bluntly: **"It's concerning that the credit market, which has been stable so far this year, is beginning to shake"** .

In Seoul, the KOSPI dropped **3.73%**, with **SK Hynix down 4.2%** and **Samsung Electronics down 3%** . And the day's most brutal story: **Elice Inc.**, a South Korean data-center company, **plunged more than 30% on its trading debut**—the worst opening day for a major Korean IPO on record .

Elice was supposed to be different. It's profitable. It's growing. It was **400 times oversubscribed** by retail investors. It still got destroyed.

That's the signal that matters: **the market is no longer paying any price for AI exposure**.

### Force #2: Oil Is Back Above $110

Brent crude rose to **$110.08 a barrel** Tuesday, extending Monday's gains as Iran escalated its threats over the Strait of Hormuz . Some reports pegged Brent as high as **$111**—its highest level in five months .

The mechanism is simple and brutal. Higher oil → higher inflation expectations → higher Treasury yields → lower valuations for growth stocks. The 10-year Treasury yield has been hovering around **5%**, a level that makes future earnings worth less today.

For American consumers, this means **gas stays above $4** and **diesel stays above $6**. For investors, it means the Fed has less room to cut rates—and more reason to keep them high.

### Force #3: The Earnings Test Is Here

The AI trade's fate may be decided after the closing bell.

**SpaceX reports tonight**. Analysts expect **revenue of $12.87 billion** and **adjusted EPS of $0.15**, driven by its AI compute rental business . But the key number isn't revenue—it's **capex**. Bloomberg consensus expects **$19.6 billion in capital expenditures**, with **$16.9 billion going to AI** . The market wants to know: when does the spending turn into returns?

**Netflix also reports tonight**. Analysts expect **revenue of $12.87 billion** and **EPS of $0.83** . But the real question is engagement. Average monthly viewing per subscriber has fallen from **66 hours in early 2023 to 49 hours in early 2026** . Co-CEO Ted Sarandos admitted the company **"isn't growing as fast as I'd like"** .

## The Human Touch: What This Means for Real Americans

Let me put this in terms that actually connect to your life.

### Your 401(k) Is Riding on Tonight's Earnings

If you own an S&P 500 index fund, you own SpaceX and Netflix. You also own CoreWeave, Nvidia, and every chip stock that's been getting hammered. The concentration of AI exposure in American retirement accounts is unprecedented.

Tonight's numbers will determine whether the selloff stabilizes or accelerates. If SpaceX shows strong AI revenue growth and Netflix beats on ad revenue, the market might find a floor. If they disappoint, expect another leg down.

### The Oil Inflation Squeeze

Every dollar Brent rises feeds into the same cycle that's been crushing household budgets all year. Gas at **$4.33**. Diesel at **$6.33**. Groceries that won't stop climbing.

The war with Iran isn't just a geopolitical story. It's a **line item in your monthly budget**. And with the Strait of Hormuz still disrupted, there's no relief in sight.

### The IPO Window Is Closing

Elice's 30% plunge isn't just a Korean problem. It's a warning for every AI company planning to go public—including **Anthropic**, which is targeting a **$2 trillion valuation** next month.

If a profitable data-center company can't survive its debut, what chance does a company burning billions have?

## Frequently Asked Questions

### Why did stocks open lower on Tuesday?

Three reasons. **AI stocks resumed their decline** after Monday's brief relief rally, led by CoreWeave and Nebius. **Oil climbed back above $110** as Iran escalated threats over the Strait of Hormuz. And **Asian markets sold off overnight**, with the KOSPI down 3.73% and Elice's IPO flopping, spreading fear globally .

### What happened to CoreWeave?

CoreWeave fell another **4.7%** in premarket trading, extending last week's collapse. The stock is now down roughly **23% over the past week** and trades near its **52-week low of $59.25** . The company's bonds remain under pressure, and credit markets are showing signs of stress globally.

### Why did Elice's IPO flop?

Elice, a South Korean data-center company, **plunged more than 30% on its first day of trading** despite being profitable and growing. Retail investors oversubscribed the offering **400 times**, but institutional buyers stayed away. The message: **investors are done paying any price for AI exposure** .

### What should I watch in SpaceX earnings tonight?

**AI revenue growth** and **capex guidance**. Analysts expect the AI segment to generate **$6.30 billion** in revenue, making it SpaceX's largest segment for the first time. But capex is expected to hit **$19.6 billion**, with most going to AI infrastructure. The market wants to see a path to profitability .

### What should I watch in Netflix earnings tonight?

**Ad revenue progress** and **engagement metrics**. Netflix's ad tier is growing, but average viewing per subscriber has fallen from **66 to 49 hours** since 2023. If Netflix can show that ads are driving revenue growth without further engagement declines, the stock could rally. If not, the 22% year-to-date decline could extend .

### Is this a buying opportunity?

I can't give personalized investment advice. What I can tell you is that **the market is in a "show-me" phase**. Elice's failure shows that even profitable AI companies are being punished. Tonight's earnings will provide the first real evidence of whether AI spending is translating into returns. Until that evidence arrives, the risk/reward is unclear.

### How does oil affect the AI trade?

Higher oil means higher inflation, which means higher interest rates, which means lower valuations for growth stocks. The 10-year Treasury yield is already near **5%**, and if oil keeps climbing, the Fed will have less room to cut. That's a direct headwind for AI companies that depend on cheap capital to fund their buildouts.

## The Path Forward: What to Watch

### Tonight's Earnings (After the Close)

**SpaceX and Netflix** report Q3 results. SpaceX's AI revenue and capex guidance are the key numbers for the AI trade. Netflix's ad revenue and engagement metrics are the key numbers for the streaming trade. Both reports will move markets.

### Oil and the Strait of Hormuz

Brent at **$110+** is the inflation trigger. Any escalation—or de-escalation—will move prices. Watch for attacks on tankers and Iranian naval activity .

### The Fed (October 27-28)

Markets are pricing a high probability of a **hold**. But if oil keeps rising and inflation stays hot, the Fed may be forced to act. A hike would be catastrophic for AI stocks.

### The AI IPO Pipeline

Elice's failure will make it harder for every AI company planning to go public. Watch for **Anthropic's IPO** next month—and whether the $2 trillion valuation target survives this new environment.

## Conclusion: The AI Trade Can't Find a Floor

Here's what I want you to take away from Tuesday's open.

Monday's rally was a **head fake**. The AI trade is still under pressure from every direction: rising oil, sticky inflation, hawkish Fed expectations, and—most importantly—**a global credit market that's starting to crack**.

Elice's 30% plunge in Seoul and SoftBank's surging credit default swaps are the signals that matter. They tell us that the fear isn't confined to American neoclouds. It's **global**. And it's spreading.

Tonight, SpaceX and Netflix report. If their numbers are strong, the market might stabilize. If they're weak, the selling resumes.

For American investors, the message is simple: **the easy money in AI is gone**. The next phase will be about proof—proof that the spending generates returns, proof that the debt can be serviced, proof that the growth is real.

The test begins tonight.
