There is this fairly sparse press-release on the SpaceX website:<p><pre><code> Space Exploration Technologies (SpaceX) has raised a billion dollars in a
financing round with two new investors, Google and Fidelity.
They join existing investors Founders Fund, Draper Fisher Jurvetson,
Valor Equity Partners and Capricorn. Google and Fidelity will collectively
own just under 10% of the company.
SpaceX designs, manufactures, and launches the world's most advanced
rockets and spacecraft. This funding will be used to support continued
innovation in the areas of space transport, reusability, and satellite
manufacturing.
