SpaceX recorded an investment gain of $561 million from its stake in The Boring Co. during the third quarter, accounting for more than half of the aerospace company's other income in the period. SpaceX's net income reached just over $4 billion, directly boosted by this return.
For Tesla shareholders, the implication is straightforward: Musk's capital allocation discipline extends beyond his core holdings. The Boring Co. operates in urban tunneling and infrastructure—distinct from SpaceX's space launch and satellite services—yet generated a nine-figure gain. At $374.58 per share, Tesla trades as a proxy for confidence in Musk's execution across his portfolio. Proof of value creation at private ventures reduces perceived operational and financial risk for TSLA shareholders, supporting multiple expansion.
The Boring Co.'s ability to deliver a half-billion-dollar return on Musk's capital suggests the company is moving toward profitability in cost-effective tunneling. If automated transport systems scale, Tesla could benefit from infrastructure tailwinds in urban mobility. More immediately, this gain validates Musk's thesis that technological synergies across disparate businesses create durable competitive edges—a thesis that directly supports Tesla's long-term valuation case.
