SpaceX has crossed a significant financial milestone: both S&P Global Ratings and Moody's assigned the company investment-grade credit ratings on June 18, 2026, following the completion of its IPO. S&P landed at BBB with a stable outlook; Moody's came in at Baa1 — also stable. For a company that spent years operating as a privately funded rocket builder, the dual ratings mark a new chapter in how Wall Street views the Elon Musk-led space enterprise.
Moody's reasoning centers on SpaceX's position as the world's leading orbital launch provider and its ownership of Starlink — the largest low Earth orbit satellite broadband network on the planet. The agency specifically called out Starlink as the primary cash flow generator, crediting it with supporting margin expansion and reducing dependence on launch revenue alone. The Baa1 rating sits two notches above Tesla's own Moody's rating of Baa3, which Tesla received in March 2023.
S&P's BBB rating takes a slightly more cautious framing. The agency acknowledged the solid foundation of SpaceX's launch and connectivity businesses while flagging the risks tied to its nascent AI ambitions and the company's aggressive capital investment requirements — which are expected to produce significantly negative free cash flow in the near term. S&P said it expects SpaceX to maintain adjusted leverage below 2.0x, a threshold the company itself committed to in its IPO filing, where it explicitly stated a goal to maintain an investment-grade credit rating.
Investment-grade status matters beyond prestige. It opens access to broader pools of institutional debt capital at lower interest rates, which is consequential for a company with the infrastructure ambitions SpaceX has — from Starship development to continued Starlink constellation expansion. The ratings also signal to institutional investors that SpaceX's financial governance has matured to public-company standards, something Moody's explicitly cited in its rationale alongside the company's balanced financial policies.
