SpaceX has informed investors it secured top-tier credit ratings, a critical milestone as the company barrels toward what could become the largest IPO in history. The company is set to price shares at roughly $135 each on June 11, with trading on Nasdaq expected to begin the following day under the ticker SPCX.

If the valuation holds near the targeted $1.75 trillion, SpaceX would debut as one of the most valuable companies on any public exchange.

The $20 billion bridge loan and what it signals

The credit ratings don’t exist in a vacuum. They’re directly tied to a $20 billion bridge loan SpaceX secured in May 2026, a pre-IPO financing vehicle designed with a clever incentive structure.

The loan carries SOFR-based interest margins that decline as SpaceX’s credit ratings improve. Specifically, the terms call for achieving a Single A rating from at least two of the three major agencies: Moody’s, S&P Global, or Fitch. Hit that threshold, and the interest margins drop significantly.
