Elon Musk’s tunneling play, The Boring Company, has raised a $3 billion Series D funding round that pushes its valuation to $23 billion.
The round was led by the United Arab Emirates. The Boring Company said Thursday that it now plans to dig more than 150 kilometers of tunnels in the Middle Eastern country. Andreessen Horowitz, Sequoia Capital, Human Capital, Vy Capital, and Valor Equity partners also participated.
