SpaceX so far has spent roughly a billion dollars developing the Falcon 1, Falcon 9, and the unmanned Dragon capsule. They will spend a bit more developing the manned Dragon (a few hundred million) and are continuing to develop other hardware such as revisions of the Falcon 9 launcher (Block 2, and an upgraded version 1.1 with considerably greater payload), the Falcon Heavy launcher (with over 50 tonnes of payload, based on the Falcon 9 1.1 core), and a fully reusable Falcon 9 launcher as well as Dragon capsule.
