Elon Musk's tunneling startup, The Boring Company, is reportedly in talks to raise a $4 billion funding round at an impressive $20 billion valuation. This would mark a significant leap from its $5.7 billion valuation in 2022.

The company has already dug under Las Vegas, where Teslas shuttle eager passengers between stations, but the project hasn't been without issues: tunnel workers have faced serious injuries and regulators have cited nearly 800 environmental violations by The Boring Company last year alone.

With plans to expand into Nashville, Dubai, Baltimore, Chicago and Los Angeles, The Boring Company seems set on transforming urban landscapes. However, the success of these ambitious projects remains contingent on overcoming regulatory hurdles and public safety concerns.

Meanwhile, SpaceX recently went through its largest IPO ever but has seen a sharp decline in stock price since then. Could Musk’s focus shift or will The Boring Company continue to thrive amidst financial turbulence?
