Elon Musk has claimed that Apple boss Tim Cook snubbed talks of a Tesla takeover in 2017.
The car manufacturer's founder insisted he contacted the tech giant's chief executive during the firm's "darkest days".
He tweeted: "During the darkest days of the Model 3 program, I reached out to Tim Cook to discuss the possibility of Apple acquiring Tesla (for 1/10 of our current value).
"He refused to take the meeting."
At the time, Tesla was valued at $45 billion ($60 billion), but it is now worth 10 times that amount.
Elon wanted to discuss a potential sale to Apple at the time, as it was struggling financially during the production of the Model 3 electric car.
