SpaceX is preparing its first bond issuance to raise $25 billion to test fixed-income investor appetite for Elon Musk’s vision for the company. Bonds would span 5- to 30-year maturities. Banks view the deal as a bellwether for further fundraising; a buy-side source said SpaceX could return in the next few years seeking roughly $10 billion more in refinancing. The planned sale comes amid a renewed large-cap tech selloff and market concern over high valuations and a rising-rate outlook.
