Boring Company in talks for $4 billion funding round at $20 billion valuation
The Wall Street Journal reports the company is seeking to raise capital amidst regulatory scrutiny and operational challenges, though the deal remains unclosed.

Elon Musk’s tunneling venture, The Boring Company, is reportedly in discussions to secure a $4 billion funding round that would value the firm at $20 billion. According to a report by The Wall Street Journal, the proposed valuation represents a substantial increase from the company’s $5.7 billion valuation recorded in 2022. The transaction has not yet been finalised, and the WSJ notes that terms are subject to change as negotiations continue.
The startup, which spun out of SpaceX in 2018, currently operates a network of tunnels beneath Las Vegas, utilising Teslas to transport passengers between stations. Beyond its existing operations, the company has announced plans to construct tunnel networks in Nashville and Dubai. The Wall Street Journal further reports that the firm has pitched similar infrastructure projects in Baltimore, Chicago, and Los Angeles, signalling an aggressive expansion strategy for its underground transit solutions.
Despite its growth ambitions, the company has faced significant operational and regulatory headwinds. Nevada regulators cited The Boring Company for nearly 800 environmental regulation violations last year. Additionally, reports indicate that tunnel workers have previously suffered serious injuries during operations, raising questions about safety protocols as the firm scales its activities.
The funding discussions occur against a backdrop of broader market volatility within Musk’s wider business ecosystem. SpaceX recently completed the largest initial public offering in history, although its share price has experienced a notable decline since the listing. While the Boring Company remains a separate entity, its valuation trajectory is often viewed in the context of the broader performance and investor sentiment surrounding Musk’s ventures.
Analysts and investors will be watching closely to see if the proposed $20 billion valuation holds as the deal progresses. The gap between the current $5.7 billion figure and the new target suggests a high level of confidence in the company’s future revenue streams from its international and domestic expansion plans. However, the unclosed status of the deal means that the final terms may differ significantly from current reports.
The Boring Company’s ability to secure this capital will be critical for funding its announced projects in Nashville and Dubai, as well as pursuing opportunities in major US cities. The company must also navigate the regulatory landscape, particularly in Nevada, where it has previously encountered strict scrutiny over environmental compliance.
