Nvidia's Twin Engines of Growth: Orbital AI Ambitions Meet a $250 Billion Balance-Sheet Question

Nvidia partners with SpaceX for orbital AI, but a $250B OpenAI lease guarantee raises circular financing concerns amid AMD's decline.

The artificial intelligence trade has a new geography. Nvidia's grip on the sector now extends from terrestrial data centers to low-Earth orbit, yet even as the company secures its most futuristic partnership yet, a more terrestrial financial question is quietly moving to the center of investor attention.

Shares of the chipmaker climbed 4.06 percent on Wednesday to EUR 191.12 after Elon Musk confirmed that SpaceX will exclusively use Nvidia processors for its forthcoming AI systems. The "Vera Rubin" architecture will anchor the partnership, which spans ground-based installations and an ambitious plan for an orbital data center. The stock has now advanced 15.06 percent over seven trading days, though it remains 5.62 percent below its 52-week high of EUR 202.50. Since the start of the year, the gain stands at 19.24 percent, with the company's market capitalization at EUR 4.342 trillion.

The SpaceX pact is not merely another contract win. It represents an attempt to transplant Nvidia's dominance from Earth into space before the first "Starmind AI1" satellites — equipped with Rubin GPUs and Vera CPUs — have even launched. Those orbital modules are slated for deployment next year and are expected to handle significantly heavier AI workloads than the H100 generation. SpaceX's own investment trajectory underscores the scale of the commitment: in the second quarter of 2026, roughly 86 percent of its USD 18.4 billion capital expenditure budget went into AI infrastructure, with compute capacity slated to grow from 2 gigawatts at the end of 2026 to 10 gigawatts by the end of 2027.

The market's reaction to the deal has been starkly binary. While Nvidia surged, AMD shares tumbled roughly 8 percent in early trading despite solid data-center growth of its own — a sign that investors increasingly view the AI chip race as a winner-take-most contest. Nvidia's competitors may fight for conventional cloud contracts, but the orbital moat now forming looks difficult to breach.

Yet for all the enthusiasm generated by the space gambit, a separate narrative is competing for investors' attention. Bloomberg and the Wall Street Journal have reported that Nvidia is negotiating a financial guarantee of up to USD 250 billion to back a ten-gigawatt data-center lease for OpenAI in Ohio. The deal remains in negotiation, with no final decision made, but its implications are already reverberating through analyst circles.

The concern centers on what some describe as "circular financing" — Nvidia effectively underwriting the very demand for its own chips. A guarantee of this magnitude would blur the line between supplier and financier, exposing the company's balance sheet to counterparty risk in ways that extend far beyond traditional supply-chain exposure. Should the OpenAI project falter or the tenant's creditworthiness deteriorate, the consequences could flow directly back to Nvidia. Analysts are now asking whether such structures represent a sustainable ecosystem or an inflated demand chain.

The timing is consequential. Nvidia trades at EUR 189.78 as of Wednesday, roughly 6.28 percent beneath its 52-week high, having gained 12.08 percent over seven sessions. The market continues to price in growth optimism, but the capital-structure question remains unresolved.

Supporters of the stock point to the breadth of partnerships Nvidia is building in parallel. Late July brought a long-term strategic alliance with Safe Superintelligence Inc., accompanied by an investment of approximately USD 5 billion and access to the forthcoming Vera Rubin platform. The company also expanded its collaboration with SK Group on next-generation AI factories and memory solutions, and agreed with NAVER and Brookfield to develop national AI infrastructure in South Korea. These deals suggest demand is being carried by multiple independent actors, not a single dominant customer.

The analyst community has taken notice. Bernstein's Varun Govindaraj reaffirmed a buy rating in early August, lifting his price target to USD 315 on the potential to break out of current trading ranges. Days earlier, Citigroup upgraded the stock to "Buy," citing an attractive risk-reward profile ahead of the quarterly report. The product pipeline — from the new cuFile storage technology to partner offerings like ASUS's MGX GPU server and cooling solutions for the Rubin architecture — continues to widen the company's technological footprint.

Skeptics see the deepening integration as the problem rather than the solution. A USD 250 billion guarantee for a single customer's leasing project would expose Nvidia's balance sheet at an unprecedented scale. Regulatory pressure adds another layer: Jensen Huang met with US Commerce Secretary Howard Lutnick in late July to discuss the ongoing review of AI chip exports to China — a matter that remains unresolved and could weigh on international demand. Insider selling has also drawn attention, with company insiders reportedly disposing of more than USD 1.8 billion worth of shares in the twelve months through July.

The stock's recent recovery has been anything but smooth. The annualized volatility over the past 30 days stands at 39.20 percent — a reminder that owning Nvidia means accepting a measure of turbulence. The next concrete test arrives on August 26, when the company reports second-quarter results. The consensus calls for revenue of approximately USD 91.8 billion and earnings per share of USD 2.08 — figures that will reveal whether demand continues to justify the mounting financial complexity.

Huang's Washington meetings underscore a role that now transcends the chip business. Nvidia operates as a strategic asset of the US economy, balancing commercial expansion against national security imperatives. The company is fighting to maintain access to global markets, particularly for its H200 chips, even as export controls remain in flux.

The SpaceX deal and the OpenAI guarantee question represent two sides of the same coin: a company aggressively securing its future while taking on risks that would have been unthinkable for a conventional supplier. If the partnership portfolio remains diversified and no single project becomes a point of failure, the circular-financing debate may stay a marginal concern. But if the USD 250 billion guarantee materializes at that scale and doubts emerge about the counterparty, the valuation could face pressure far beyond what the current proximity to the yearly high suggests. For now, the market watches both the stars and the balance sheet.
