Tesla Motors was incorporated in July 2003 by Martin Eberhard and Marc Tarpenning, who financed the company until the Series A round of funding. Both men played active roles in the company's early development prior to Elon Musk's involvement.
Responding to a screenshot of a CNN headline that read, “2% of Elon Musk’s wealth could help solve world hunger, says director of UN food scarcity organization,” Musk tweeted that if the U.N. World Food Program “can describe on this Twitter thread exactly how $6B will solve world hunger, I will sell Tesla stock right now and do it.”
WFP director David Beasley called his bluff, and actually outlined how the organization would use the $6.6 billion. Musk, who is worth approximately $239.2 billion, never responded to Beasley.
