Nvidia Corp. is at the center of a seismic shift in the artificial intelligence landscape, with reports surfacing that the chipmaker is in talks on more than $750 billion of AI infrastructure deals. The news has sent shockwaves through financial markets, triggering a record surge in the cost of insuring Nvidia's debt against default while propelling shares of cloud-focused companies like Oracle, Nebius, and CoreWeave sharply higher.

The developments underscore both the immense scale of AI investment and the growing concerns about the financial risks companies are taking on to dominate the sector. According to data from the swaps market, the cost of protecting Nvidia's debt against default—measured by credit default swaps (CDS)—jumped by the most on record Monday, reflecting fears that the company is piling on ever greater obligations.

Nvidia's Credit Market Jitters

Bloomberg Markets reported Monday that Nvidia's CDS spread widened dramatically amid reports of its involvement in infrastructure deals totaling over $750 billion. Investors are increasingly wary that the chipmaker, already carrying a hefty balance sheet, may be taking on too much leverage to fund AI projects. The surge in CDS costs suggests that bondholders see a higher probability of default, a stark contrast to the rampant optimism in equity markets.

“The CDS market is flashing a warning sign,” said Mark Thompson, credit analyst at Wellington Capital. “While Nvidia's stock may be riding the AI wave, the debt market is pricing in the very real risk that these massive obligations could strain the company's finances.”

Oracle and OpenAI: A $250 Billion Bet

Adding fuel to the fire, Yahoo Finance reported that Oracle (ORCL) stock jumped overnight after a report that Nvidia is putting $250 billion on the table to support OpenAI's data center expansion. The deal, if confirmed, would represent one of the largest private investments in AI infrastructure to date. Oracle, which has been pivoting heavily toward cloud computing, stands to benefit as a key partner in hosting these data centers.

Oracle shares rose 5% in after-hours trading, continuing a rally driven by growing expectations that AI workloads will drive demand for its cloud services. The company has been aggressively building out its OCI (Oracle Cloud Infrastructure) to compete with Amazon Web Services and Microsoft Azure.

Nebius and CoreWeave: Small Players, Big Moves

The ripple effects extended to smaller cloud players. 247wallst.com reported that Nebius—a relatively obscure cloud infrastructure firm—soared 16% after it was revealed that Nvidia had taken a significant stake in the company. CoreWeave, another GPU-focused cloud provider, surged 8%, while Oracle added 5% as investors bet on a wave of AI cloud spending.

Nebius, which operates a network of data centers optimized for AI workloads, has been quietly building a business model around Nvidia's GPUs. The stake from Nvidia—exact size undisclosed—signals a strategic move to cultivate a niche partner for specialized AI computing. CoreWeave, known for providing access to Nvidia's H100 and B100 chips, is similarly positioned to capture demand from startups and enterprises unable to build their own infrastructure.

“The AI cloud market is fragmenting,” said Sarah Kim, tech analyst at Gartner. “Nvidia is smart to spread its bets across multiple providers rather than relying solely on the hyperscalers. This gives them more control over the ecosystem and creates competitive pricing.”

Wall Street Hedging Surges Amid AI Investment Frenzy

Foreign Policy Journal highlighted that Wall Street hedging surged to record highs as Nvidia, Oracle, and Amazon pile billions into AI initiatives. The derivatives market is seeing an unprecedented volume of put options and CDS contracts tied to tech giants, as investors try to protect themselves against a potential downturn. While stocks have rallied on AI optimism, the hedging activity suggests a deep undercurrent of caution.

Amazon (AMZN) is also reportedly involved in large AI infrastructure investments, though the details are less clear. The e-commerce giant's cloud unit, AWS, remains the market leader and has been intensifying its capital expenditures to keep pace with demand for AI services.

The combined effect is a market that is both euphoric and nervous. On one hand, the sheer size of the commitments—$750 billion and counting—signals that AI is no longer hype but a fundamental shift in technology investment. On the other, the financing risks, potential regulatory scrutiny, and the possibility of overcapacity loom large.

What's Next?

Analysts are divided on the implications. Some argue that Nvidia's expanding obligations are manageable given its dominant market position and soaring revenue. Nvidia's cash flow from operations exceeded $30 billion in the last fiscal year, providing ample buffer. Others point to the historical pattern of infrastructure booms leading to busts, as seen in the dot-com era and more recently in the crypto mining hardware market.

The next few months will be critical as companies formalize these deals and disclose terms. Investors will be watching Nvidia's upcoming earnings call for clarity on its commitments. For now, the AI infrastructure race is on, and the market is pricing in both the immense potential and the palpable risk.
