Republican defeat depresses Tesla shares Coinciding with the electoral defeat of the Republicans in America, Tesla shares fell 5% and SpaceX 6.9% in pre-open trading. Musk, who has spent about $450 million to support Republicans, now faces the prospect of tougher artificial intelligence laws, restrictions on government contracts and uncertainty over Tesla and SpaceX's planned merger. On the other hand, SpaceX's dependence on multibillion-dollar contracts from the US government and Musk's reliance on future-oriented projects such as self-driving cars and artificial intelligence have fueled investor concerns. - link.
