A few years ago, Elon Musk tried to interest Apple CEO Tim Cook in buying Tesla, Musk said in a Tuesday tweet . "He refused to take the meeting," Musk added.

According to Musk, this occurred in the "darkest days of the Model 3 program"—most likely some time in late 2017 or early 2018. Musk recently revealed that at one point early in the Model 3 manufacturing process, Tesla was "about a month" away from bankruptcy

"The Model 3 ramp was extreme stress & pain for a long time — from mid 2017 to mid 2019," Musk wrote in November . "Production & logistics hell."

Tesla is planning to raise another $5 billion from Wall Street, the company announced in a Tuesday morning filing with the Securities and Exchange Commission. It will be the company's third round of fundraising this year and will bring its 2020 fundraising to $12 billion.

It's a good time for Tesla to raise money because Tesla's stock price hit a record high of $640 on Tuesday—a more than seven-fold increase since the start of 2020. Tesla's market capitalization is now around $600 billion, which means that Tesla's existing shareholders will give up less than 1 percent of their stake from the stock sale.

Still, investors didn't seem thrilled at the news, with Tesla's share price down a little more than 1 percent in morning trading.
