SpaceX is raising yet another round of funding, a month after completing its second fundraising of the year.

The latest round, filed on Monday, seeks to raise $314.2 million at a price of $214 a share, according to a document seen by CNBC. The new equity would bring SpaceX's total 2019 fundraising to $1.33 billion once completed.

The company declined to immediately comment on the filing.

Part, if not all, of the investment in SpaceX is from the Ontario Teachers' Pension Plan, which has $191.1 billion in assets under management. The investment is the first by a new technology fund that Ontario Teachers' launched in April.

"SpaceX is the world's leading private space launch provider, and we are excited to work with the company in the next phase of its growth as it rolls out its Starlink satellite network," Teachers' Innovation Platform fund senior managing director Olivia Steedman said in a statement.

Ontario Teachers' said that SpaceX was seen as a "a compelling investment opportunity" for the fund because of "its proven track record of technology disruption in the launch space and significant future growth potential in the satellite broadband market."

SpaceX raised equity rounds of $486 million and $536 million earlier this year. Before this latest round, SpaceX's valuation had risen to $33.3 billion, people familiar told CNBC in May.

Elon Musk's company is bankrolling two capital intensive projects: Starlink, a network of thousands of small internet satellites, and Starship, a massive rocket to send people and cargo to Mars.
