CEO Elon Musk has indicated that he will personally buy $25 million of Tesla shares.
The news caused the company's share price to climb by more than three percent in after-hours trading.
Just last month Musk hinted at the capital raising saying Tesla was "close to the edge" in terms of its cash needs.
Tesla had $3.39 billion in cash and cash equivalents at the end of 2016 but has indicated that it plans to spend up to $2.5 billion in the first half of this year before beginning production of the Model 3.
