On the heels of the Fourth of July -- and amid his feud with President Donald Trump and congressional Republicans over the president's tax policy bill -- tech billionaire Elon Musk announced plans for a brand new political party, dubbed "America Party," to represent what he called "the 80% in the middle."

Elon Musk's net worth has taken a $15.3 billion hit after the Tesla CEO announced he was to form a new political party. The news sent ripples through financial markets and spooked investors concerned about Musk's political ambitions and possible implications for Tesla's brand and business operations.

Musk said he wants to form the America Party. A third party has never won the presidency, but they have influenced elections, experts say — mostly as spoilers.
