Two Reasons Why Nvidia’s Stock Saw Its Biggest Weekly Surge in More Than a Year

## The chip maker recorded its largest-ever weekly increase in market capitalization, adding $562 billion in value after a major endorsement from Elon Musk and confirmation that Big Tech's AI spending spree is far from over.

### Introduction: A $562 Billion Week

Just when it seemed like the AI trade might be cooling, Nvidia delivered a performance that reminded investors why it remains the most important company in the artificial intelligence revolution. The chip maker's stock rose 11.6% for the week ending August 7, 2026—its best weekly performance since May 2025 . More remarkably, Nvidia added **$562 billion** to its market capitalization, the largest single-week gain in the company's history .

The surge lifted Nvidia's market cap to roughly **$5.36 trillion**, returning it to levels not seen since early June . What drove this historic rally? Two catalysts: a blockbuster endorsement from Elon Musk's SpaceX and the continued confirmation that hyperscalers are spending unprecedented amounts on AI infrastructure.

### Catalyst 1: Elon Musk's "Exclusive" Endorsement

The week's rally began on Tuesday, August 4, when SpaceX held its first earnings call as a public company. CEO Elon Musk used the occasion to deliver what amounted to the most powerful endorsement any chipmaker could ask for .

"We have decided to build exclusively on Nvidia" moving forward, Musk said . He called Nvidia's upcoming **Vera Rubin chip architecture** "the best AI computer" and said SpaceX "greatly value[s] our close cooperation and partnership on many levels with Nvidia" .

Musk went further. He said SpaceX expects to receive "a very significant percentage" of Nvidia's GPU output next year, when the company plans to install close to **10 gigawatts** of compute capacity . That's a staggering amount of computing power—enough to train and run some of the world's largest AI models.

BNP Paribas analyst Stefan Slowinski said Musk's commentary raises the question of whether GPU availability "could once again emerge as a key constraint on AI-infrastructure deployments" in the next 12 to 18 months . SpaceX's suggestion that memory output is growing at about 20% annually while AI demand is growing at a **200% clip** supports the view that supply is still severely lagging demand . As Slowinski noted, "Even if directionally accurate, this suggests that the current favorable pricing environment is unlikely to normalize any time soon" .

### Catalyst 2: Hyperscaler Spending Confirms Demand Is Real

While Musk's endorsement grabbed headlines, the "bigger story" is "how much the major hyperscalers are spending on AI infrastructure right now," according to Kate Leaman, chief market analyst at AvaTrade .

In the weeks leading up to Nvidia's surge, Alphabet, Amazon, and Meta all guided their capital expenditures higher for the year . Together, Big Tech firms have disclosed a combined **$650 billion** in planned AI infrastructure spending for 2026 . Amazon anchored the wave with plans for approximately $200 billion in capital investment .

Willy Lee, a principal at investment firm Neostellar, told MarketWatch that while Google's first bout of quarterly negative free cash flow spooked investors, Microsoft's "more measured approach" to capex and its accelerating cloud growth showed investors a more positive view of all that spending .

Nvidia also secured a $1.5 billion multi-year agreement with Amkor Technology to expand advanced chip packaging and test capacity in the U.S., deepening an existing relationship that helps lock down capacity before the next wave of AI demand arrives .

### The Sovereign AI Tailwind

Beyond hyperscalers, Nvidia is also benefiting from the rise of **sovereign AI**—nation-state investments in domestic AI infrastructure. According to Counterpoint Research, **92% of sovereign AI models** are trained using Nvidia chips . Revenue from sovereign AI has more than tripled year-over-year, surpassing $30 billion .

Nvidia is using its dominant position to secure multi-billion-dollar partnership agreements across the globe, positioning itself for the next wave of AI expansion .

### What This Means for Investors

The $562 billion weekly gain brings Nvidia stock to roughly **$221**, up about 17% in 2026 . The stock trades at a forward P/E of about 22 times fiscal 2026 earnings and below 16 times next year's consensus of $12.89 .

The next major catalyst is Nvidia's own earnings report, due **August 26** . Wall Street expects revenue of roughly **$91.8 billion** and EPS around **$2.08**—both slightly above management's guidance of about $91 billion in revenue . Leaman noted that "some traders are clearly positioning ahead of that" report . But with expectations already high, a pullback is possible .

### Key Catalysts to Watch:

- **August 26 Earnings Report**: Revenue expected ~$91.8 billion, EPS ~$2.08

- **Vera Rubin rollout**: Nvidia's next-generation architecture, delivering 10x performance per watt

- **HBM supply constraints**: Nvidia testing lower-HBM configurations of Rubin Ultra to address global memory shortages 

- **Regulatory risk**: U.S. officials investigating Chinese AI access through overseas data centers

### Conclusion: The AI King Remains on the Throne

Nvidia's record-breaking week is a powerful reminder that the AI infrastructure buildout is still in its early innings. The combination of hyperscaler spending, sovereign AI investments, and a deepening relationship with companies like SpaceX paints a picture of demand that shows no signs of slowing.

As Nvidia prepares to report earnings on August 26, the question isn't whether demand is strong—it's whether the market has already priced in the good news. With the stock trading at its highest level since June, investors will be watching for any sign that the growth narrative is intact. Given the spending commitments from Big Tech and Musk's endorsement, the case for Nvidia's continued dominance remains as compelling as ever.
