How did Tesla become the most polarizing company in stock market history? In this episode of "The Big Story," Grant Williams explores the fierce debate between those who believe in Elon Musk's vision, and the obsessive community of short sellers who sees massive corporate fraud. The lines are drawn and the battle sometimes gets personal in a story that encapsulates the divides that define the 21st century. Tesla is more than just an electric car company — it represents our obsession with Silicon Valley and celebrity culture, the promise of green energy and AI, the corrosive impact of social media, and a roaring stock market that could soon come crashing down. Filmed from August 2018 to March 2019 in New York, San Francisco, Los Angeles and other locations.
