Tesla boss Elon Musk has sold shares worth around $4 billion in total in the electric car maker, going by filings with the regulator.
About 4.4 million shares were offloaded on Tuesday and Wednesday, the filings with the Securities and Exchange Commission revealed.
Tesla CEO said no further sales have been planned. "No further TSLA sales planned after today," Musk said in a tweet.
This comes as reports say Musk's initial nine percent stake purchase in Twitter is being probed by the Federal Trade Commission (FTC).
