on Thursday after a public feud between President Donald Trump and CEO Elon Musk led to the stock's biggest single-day drop ever. The gains from betting against the EV maker were the second biggest, data from analytics firm Ortex showed. Traders had pocketed $5.4 billion from a selloff on September 8, 2020, after the firm was looked over for inclusion into the S&P 500 index.

The stock closed down 14.3% on Thursday and lost about $150 billion in market value.

With short sellers up $7.5 billion on their bet against Tesla, it remains the most profitable trade for the bearish investors among the "Magnificent 7" stocks this year. Apple stands second at $7.3 billion, according to Ortex.
