Heston, who said he was paid $300,000 to $350,000 for his work in the case, demurred on trying to make a concrete estimate on the investor damages, saying that was a job for the jurors.

The crux of the case hinges on an Aug. 7, 2018, tweet in which Musk declared “funding secured ” to take Tesla private. Musk abruptly posted the tweet minutes before boarding his private jet after being alerted that the Financial Times was about to publish a story that Saudi Arabia’s Public Investment Fund had spent about $2 billion buying a 5% stake in Tesla to diversify its interests beyond oil, according to his testimony.

Amid widespread confusion about whether Musk’s Twitter account had been hacked or he was joking, Musk followed up a few hours later with another tweet suggesting a deal was imminent.
