Elon Musk's Boring Company Raises $3 Billion in Series D Funding for UAE Expansion

The Boring Company and Dubai’s Roads and Transport Authority signed a preliminary agreement for the Dubai Loop in 2025, establishing a formal basis for the project’s development.
The Series D is The Boring Company’s largest capital raise to date, according to the company’s announcement and follow-up reporting.
Before the new expansion plans, the company was primarily known for operating a single 1.7-mile tunnel beneath the Las Vegas Convention Center.
The Boring Company was founded by Elon Musk in 2017 after he criticized traffic congestion and began proposing underground transportation networks.
Elon Musk's Boring Company has raised $3 billion in a Series D funding round led by the United Arab Emirates, pushing the tunneling startup's valuation to $23 billion TipRanks. The massive capital infusion—the company's largest to date—will fund over 150 kilometers of underground transportation infrastructure across the UAE, with the Dubai Loop project taking center stage VentureBurn.
The funding round marks a dramatic jump from the company's $5.7 billion valuation in 2022. Major investors include Sequoia Capital, Andreessen Horowitz, Temasek, Vy Capital, and Valor Equity Partners TipRanks. The Boring Company plans to expand its Las Vegas and Nashville Loop projects and hire aggressively across engineering, production, and operations roles VentureBurn.
The Boring Company started small. In 2017, Elon Musk founded the company after criticizing traffic congestion in Los Angeles. For years, its only operational project was a 1.7-mile tunnel beneath the Las Vegas Convention Center VentureBurn. That single tunnel proved the concept worked. Now the company is ready to scale globally.
The Boring Company and Dubai's Roads and Transport Authority signed a preliminary agreement in 2025 to build the Dubai Loop, establishing the formal foundation for development TipRanks. The network will span more than 150 kilometers of underground transport tunnels across the UAE's most congested urban areas. The project represents a massive leap in scope compared to the company's previous work.
The funding consortium reads like a who's who of Silicon Valley. Sequoia Capital, Andreessen Horowitz, and Vy Capital all joined the round, alongside strategic investors Temasek, Shamal Holding, and Baron Capital TipRanks. The enthusiasm signals growing confidence that underground tunneling can solve urban congestion at scale—a bet venture capitalists were reluctant to make just five years ago VentureBurn.
With $3 billion in hand, the Boring Company is hiring across engineering, production, and operations TipRanks. The company plans to expand Loop projects not just in Dubai but also in Las Vegas and Nashville. These new roles will support tunnel design, construction equipment development, and project management across all three markets.
