Only a few months have passed since SpaceX went to the public bond market for the first time with a $25 billion issuance, but the company is already looking at new ways to borrow more money to fund its stratospheric ambitions.

"There are a number of available pools of debt capital that we are talking to at the moment, related to funding this incredible growth," chief financial officer Bret Johnsen said Tuesday during the earnings call with analysts and investors.

Johnsen called SpaceX's investment grade bond rating an advantage. The bonds of a shakier "neocloud" company, CoreWeave, sold off last week.
