Investing.com -- Tesla Inc. received government clearance to convert its investment in Elon Musk's xAI into a stake in SpaceX, according to filings with the US Federal Trade Commission dated Wednesday.

The filings list Tesla as the acquirer of a stake in SpaceX from Musk, who serves as chief executive officer of both companies. The documents also show Musk selling holdings to investors including Valor Equity Partners and DFJ Growth.

While the filings are required for transactions valued at more than $133.9 million, the size of the stakes was not disclosed.

The Tesla filings relate to its previously announced $2 billion investment in xAI, which is being rolled over into SpaceX following the recent merger of the AI firm with the space-launch company, Bloomberg reported Thursday. That investment would equate to a stake for Tesla of less than 1%.

The conversion formalizes the financial ties between Musk's two biggest businesses ahead of the rocket maker's planned initial public offering.
