SpaceX said Thursday that its stake in Elon Musk's The Boring Co. produced a $561 million investment gain in the third quarter, a result the company disclosed in its quarterly financial filing with the Securities and Exchange Commission.
The gain accounted for more than half of SpaceX's "other income" for the period and helped push net income to just over $4 billion, the filing showed.
What Boring Co. does
Boring Co. was created inside SpaceX in 2017 and spun out a year later. It describes its mission as to "revolutionize transportation" by building underground tunnels with stations where passengers can board and exit.
Last month the tunneling company raised $3 billion at a $23 billion valuation, with backing from the United Arab Emirates and a roster of other longtime Musk supporters.
Projects and scrutiny
Boring Co. has announced about a dozen city projects, but its only tunnels currently open for public use are in Las Vegas. There, passengers travel in Tesla vehicles between the downtown convention center and various casino resorts using the Las Vegas Convention Center Loop.
In July of last year, the company struck a deal to build about 20 miles of tunnels in Nashville, Tennessee. Known as the Music City Loop, the project is being designed to carry paying passengers between downtown and the airport in Tesla vehicles. The fast-tracked project sparked a partisan feud when it was greenlit and has drawn new safety concerns this week over sinkhole risks.
In the UAE, Boring Co. plans to build over 150 kilometers (93 miles) of tunnels, including the Dubai Loop announced in February of last year.
Tesla ties and merger talk
SpaceX also said in the filing that it purchased $151 million worth of Tesla's Megapack energy storage systems during the quarter.
On SpaceX's earnings call Tuesday, Musk said he thinks it would be a "good idea" for the two companies to merge, and said they have both created special committees to discuss a potential transaction.
Musk has expanded a number of his companies within Texas, including Tesla, SpaceX, Boring Co. and Neuralink. Tesla broke ground on a lithium refinery in Texas earlier this year, with Governor Greg Abbott in attendance.
