Elon Musk, the CEO of Tesla, claims to have donated approximately $1.95 billion (£1.6 billion) worth of company shares to charity last year.
In a filing with US regulators, the donation of 11.6 million shares was referred to as “a bona fide gift.”
The donation’s recipient or recipients were not identified in the filing.
Also on Wednesday, Mr. Musk stated that it would be “good time” to find a replacement for him as Twitter’s CEO towards the end of the year.
The document submitted to the US Securities and Exchange Commission states that the donation was made between August and December of last year.
A BBC request for comment has received no immediate response from Tesla.
It is not the first time Mr. Musk has given Tesla stock to charity. He donated around $5.74 billion worth of shares in 2021, according to a regulatory filing.
He also said on Twitter that year, that he planned to donate $20m to schools in Cameron County and $10m to the Brownsville city in Texas, US for “downtown revitalization”.
Mr Musk has also hinted that he plans to find his successor as chief executive of Twitter by the end of 2023.
“I’m guessing probably towards the end of this year would be good timing to find someone else to run the company, because I think it should be in a stable position around, you know, at the end of this year,” he said.
“I think I need to stabilise the organisation and just make sure it’s in a financially healthy place and that the product roadmap is clearly laid out,” he said on a video link at the World Government Summit in Dubai.
The multibillionaire businessman bought the social media platform last year for $44 billion. He has since said the company was close to bankruptcy.
However, he has been criticised by some Tesla investors for spending too much of his time focussing on trying to turn around Twitter.
In November, addressing the G20 Summit in Bali, Indonesia, Mr Musk said he is working too much as he juggles his responsibilities as Twitter, Tesla, and his rocket company SpaceX.
“My workload has recently increased quite a lot,” Mr Musk said. “I have too much work on my plate, that is for sure,” he added.
