Tesla hopes to raise $2 billion by selling new shares.

The car manufacturer said it would issue new shares to raise up to $2.3 billion in capital, just weeks after Elon Musk said it "doesn't make sense to raise money."

Musk has now said he'll personally buy $10 million worth of stock in the new offering. Tesla's shares have risen over 83% so far this year, though they fell by 4% following Thursday morning's news.
