Tesla chief executive Elon Musk is close to getting a windfall that would dwarf any payday for star Silicon Valley executives as the electric-car maker predicts it could reach a key milestone within months.

As FN’s sister-publication MarketWatch reported in January, as part of a performance-award agreement in Musk’s 2018 compensation package, the Tesla CEO stands to receive options to purchase shares if Tesla reaches certain benchmarks, an important one being a market capitalisation averaging $100bn for six months.
