Elon Musk's Boring Company Reportedly in Talks to Raise $4B at $20B Valuation

The Boring Company founder Elon Musk

The Boring Company, the tunneling and underground transportation startup founded by Elon Musk in 2016 and led day-to-day by president Steve Davis, is reportedly in talks to raise approximately US$4 billion in new funding at a US$20 billion valuation, according to a Wall Street Journal report cited by TechCrunch on July 25. The deal has not closed, and terms could still change before it does; neither the company nor Musk has publicly commented on the report. If finalized at that price, the valuation would be more than triple the roughly US$5.7 billion investors assigned the company in its last confirmed funding round, a US$675 million Series C led by Vy Capital and Sequoia Capital in April 2022.

Spun out of SpaceX, The Boring Company builds tunneling machines and operates underground transportation systems using Tesla vehicles. Its flagship project, the Las Vegas Convention Center Loop, has carried roughly 3.5 million riders since opening in spring 2021 and currently spans about 4 miles of tunnels, with a station serving Harry Reid International Airport targeted for early 2026; the company's long-term plan calls for 68 miles of tunnels and 104 stations capable of moving 90,000 people an hour. The company is also building a Dubai tunnel network, whose first 6.4-kilometer phase broke ground in February 2026 and is expected to open in 2027, and has announced a Nashville airport-to-downtown project, while earlier pitches for Chicago, Baltimore, and Los Angeles have stalled or been abandoned.

Market Context

The reported valuation jump comes as tunneling costs remain a central challenge for the company: Boring Company currently spends roughly US$10 million per mile of tunnel, with an internal goal of cutting that to US$3 million to US$4 million per mile within two to five years, a cost reduction central to the company's pitch that underground transit can be built far more cheaply than traditional subway systems. The company has also faced regulatory scrutiny, including nearly 800 alleged environmental violations reported by Nevada regulators in 2025 and prior citations from Texas environmental regulators at its Bastrop headquarters, along with reports of serious injuries among tunnel workers.

The fundraising talks also land amid heightened attention on Musk's broader corporate empire: sister company SpaceX completed the largest initial public offering on record in June 2026 at US$135 a share, though its stock has since declined significantly. A valuation near US$20 billion for a company that, nearly a decade after its founding, still operates a single fully realized passenger loop in Las Vegas would represent a striking bet by investors on Musk-affiliated infrastructure ventures, even as some of his other companies face public market volatility.

The Number

$20 billion. That is the valuation The Boring Company is reportedly seeking, more than triple the roughly $5.7 billion it was assigned in its last confirmed funding round in 2022, for a company that, after nearly a decade, has fully built out just one operational passenger tunnel loop.

Regional Relevance

For the United States: A funding round at this scale would reinforce investor confidence in privately funded alternatives to traditional public transit infrastructure at a moment when many US cities continue to struggle with the cost and pace of building new subway and rail systems. Nevada, in particular, remains the company's proving ground, and the pace and safety record of the Las Vegas Loop's expansion, including regulatory violations already on record, will likely shape how other US cities weigh future Boring Company pitches after Chicago, Baltimore, and Los Angeles proposals previously stalled.

For Dubai and the company's international expansion: The Dubai tunnel project, now under construction with an expected 2027 opening, represents Boring Company's most concrete bet outside the United States, and a higher valuation could accelerate its ability to fund that and future international projects. For Gulf-region policymakers investing heavily in futuristic infrastructure, a successful Dubai Loop would offer a real-world test of whether Boring Company's tunneling technology can scale reliably outside the more permissive regulatory environment it has enjoyed in Nevada and Texas.

The Other Side

Does a single operational tunnel loop after nearly a decade justify a $20 billion valuation? The company has canceled or stalled proposed projects in Chicago, Baltimore, Los Angeles, Fort Lauderdale, and San Antonio, and its only fully built-out system remains the Las Vegas Loop; investors betting on this valuation are pricing in future execution across Nashville, Dubai, and further Vegas expansion that has not yet been delivered.

Do the reported safety and environmental issues raise questions about the pace of expansion? Nevada regulators have alleged nearly 800 environmental violations in a single year, and workers have reportedly suffered serious injuries during tunneling operations; a valuation jump that assumes rapid buildout to 68 miles of tunnels raises the question of whether the company can scale construction without compounding those problems.

How much of this valuation reflects Boring Company's own fundamentals versus broader enthusiasm for Musk-affiliated ventures? The report surfaces just weeks after SpaceX's record IPO, and skeptics could argue that investor appetite for Musk's private companies, rather than Boring Company's standalone financial or operational progress, is driving the number, a distinction that will only become clear if and when the round actually closes on the terms reported.
