Analysis
Elon Musk's tunneling company, The Boring Company, is in talks to raise approximately $4 billion in new funding at a valuation of roughly $20 billion, according to the Wall Street Journal -- more than triple its last publicly known valuation of $5.7 billion from 2022. The deal has not closed, and people familiar with the discussions caution that terms could still change before any round is finalized.
The Boring Company builds underground tunnel systems for cars and, eventually, other transit, with its most visible project being the Vegas Loop system beneath the Las Vegas Convention Center and surrounding areas. Unlike most of Musk's other ventures, Boring has historically disclosed almost nothing about revenue, contract backlog or unit economics, making a valuation jump of this size difficult to underwrite from public information alone.
The raise lands amid a broader pattern across Musk's company portfolio in 2026: SpaceX completed its IPO, xAI merged with SpaceX in a deal reportedly valued near $250 billion, and Neuralink has been raising at escalating valuations of its own. Investors backing any one of these entities are increasingly making a bet on Musk's overall execution and capital-allocation discipline across a sprawling set of companies simultaneously, rather than underwriting any single business's standalone fundamentals.
For infrastructure and deep-tech investors, Boring's valuation jump is a useful signal that capital is willing to flow into unglamorous, capital-intensive physical infrastructure plays if they carry a recognizable enough name attached -- a dynamic that smaller, non-Musk-affiliated tunneling and infrastructure startups will likely struggle to replicate on their own merits.
What to watch: whether the $4 billion round actually closes at the reported terms, whether Boring discloses any real revenue or contract figures as part of the raise, and whether other Musk-affiliated entities raise at similarly steep multiples this year.
