Elon Musk has secured about $7.1 billion of new financing commitments, including from billionaire Larry Ellison, a Saudi Prince, and Sequoia Capital, to help fund his proposed $44 billion takeover of Twitter Inc. The equity commitments from 19 investors come as the Tesla Inc. billionaire marshals capital to bankroll one of the biggest tech industry takeovers. Musk had originally said he planned to fund the deal in part with a $12.5 billion loan against his shares in Tesla, the electric-vehicle company he runs.
