SpaceX has earned a higher credit rating than Tesla, not because rockets are inherently safer investments, but because the company has built a rapidly growing cash-generating business that can fund its most ambitious bets. Fitch Ratings assigned SpaceX a BBB+ rating in June, one notch above Tesla's BBB rating, a distinction that reveals how creditors evaluate Elon Musk's two capital-intensive empires.

What's Driving the Credit Rating Gap?

The difference comes down to predictable cash flows and what each company is asking creditors to fund. Tesla is spending heavily on artificial intelligence (AI) compute, robotaxi development, the Optimus humanoid robot, semiconductor manufacturing, and other expansion projects. The company's 2026 capital expenditures are expected to exceed $25 billion, roughly three times its 2025 spending.

Fitch expects this spending to push Tesla into negative free cash flow territory for at least the next several years, despite the company holding $43.5 billion in cash and marketable securities as of June 30. Tesla also said it could secure up to $30 billion in debt facilities to accelerate those investments, adding to the financial uncertainty that creditors must evaluate.

SpaceX, by contrast, has something Tesla is still building: a rapidly growing recurring-revenue engine. Starlink, the company's satellite internet service, reported 12 million subscribers at the end of the second quarter, with connectivity revenue reaching $4.3 billion, up 66 percent year over year. During that same quarter, connectivity generated $2.6 billion in adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA), giving SpaceX a growing cash-generating business alongside its launch operations.

"SpaceX can pursue ambitious projects such as Starship and AI infrastructure while leaning on an established connectivity business that is already generating significant cash earnings," noted Fitch in its rating analysis.

That distinction matters enormously to creditors. SpaceX reported more than $90 billion in pro forma liquidity and expects EBITDA growth to keep leverage at or below management's 2 to 3 times target range. The company's commercial launch business is also well-established, with SpaceX launching 170 rockets in 2025 alone, making it the world's most active launch provider.

How Does Starlink Support SpaceX's Ambitious Goals?

Starlink's financial contribution is crucial to understanding why SpaceX can pursue expensive projects like Starship, its fully reusable super-heavy-lift launch vehicle. SpaceX is preparing for Flight 14, the 14th full-stack test of Starship, which is scheduled to launch during a 75-minute window opening at 8:15 a.m. EDT on September 28. This mission represents Starship's first attempt at reaching orbit, a major milestone for the launch vehicle that has been in development for 10 years.

If successful, Flight 14 will deploy 26 Starlink Version 3 (V3) satellites, the first in a constellation that Musk hopes to grow to more than 100,000. The larger, more powerful V3 satellites will eventually replace the existing Starlink network and, according to Musk, will occupy low Earth orbit alongside an even larger network of more than 1 million AI data center satellites, pending regulatory approval.

The financial model is straightforward: Starlink's current revenue stream funds the development and testing of Starship, which in turn will deploy the next generation of Starlink satellites. This creates a self-reinforcing cycle that creditors find more predictable than Tesla's approach, where the company is asking investors to finance a dramatic expansion into physical AI, autonomy, and robotics while its core auto business faces margin pressure.

Key Factors Behind the Rating Difference

• Revenue Predictability: SpaceX's Starlink service has 12 million subscribers generating $4.3 billion in annual revenue with 66 percent year-over-year growth, providing a stable foundation for investment in new projects.
• Capital Efficiency: SpaceX's EBITDA margins from connectivity operations reached $2.6 billion in a single quarter, allowing the company to fund Starship development without depleting cash reserves or requiring massive debt facilities.
• Business Diversification: SpaceX operates two distinct revenue streams, commercial launches and satellite internet, whereas Tesla is concentrating capital on unproven technologies like robotaxis and humanoid robots.
• Leverage Management: Fitch expects SpaceX to maintain leverage at or below 2 to 3 times EBITDA, a conservative range that suggests the company can manage debt while pursuing ambitious projects.

Tesla, meanwhile, faces a different challenge. The company's EBITDA margins have remained in the mid-teens in recent years, and while the company has strong liquidity, the sheer scale of its planned spending creates uncertainty for creditors. The company is asking investors to believe that robotaxis, Optimus robots, and AI compute infrastructure will eventually generate returns comparable to or exceeding its current automotive business, but those businesses are not yet generating revenue.

What Does This Mean for Investors and Creditors?

The one-notch gap between Tesla's BBB and SpaceX's BBB+ rating offers a useful snapshot of how creditors view Musk's two capital-intensive empires. Both companies are betting billions on futuristic technologies, but SpaceX has a proven, growing business that can absorb the risk of those bets. Tesla is asking creditors to finance a dramatic transformation while its core business faces margin pressure from increased competition and slowing electric vehicle adoption.

For SpaceX, the rating reflects confidence that the company can continue launching rockets, growing Starlink's subscriber base, and developing Starship without jeopardizing its financial stability. For Tesla, the rating reflects the uncertainty created by the size and scope of its AI and robotics spending relative to its current cash generation.

As SpaceX prepares for Starship's orbital debut and continues expanding Starlink's global footprint, the company's financial model appears increasingly attractive to creditors. Tesla, by contrast, will need to demonstrate that its investments in robotaxis and humanoid robots can generate returns comparable to its automotive business before creditors become more confident in its long-term financial trajectory.
