(Reuters) - Billionaire Elon Musk's SpaceX is poised to become the most valuable U.S. startup as its valuation rose to over $125 billion in an ongoing share sale in the secondary market, sources familiar with the matter told Reuters.

The shares, which are marketed at about $72, jumped in valuation from last October, when SpaceX's shares were sold at $56 apiece after a 10-1 split and valued the rocket company at $100 billion.
