Elon Musk’s estimated net worth rose by approximately US$61 billion in a single trading day as shares in SpaceX and Tesla advanced, bringing his fortune close to the US$1 trillion mark, according to Forbes’ Real-Time Billionaires List.
Forbes reported on October 2 that Musk’s estimated wealth reached US$979.7 billion at approximately 2:15 p.m. Eastern Daylight Time, representing a 6.64 per cent increase from the previous day’s estimate.
The increase was linked to gains in the market value of his business interests, rather than a cash payment of US$61 billion to Musk.
SpaceX and Tesla shares climb
SpaceX shares were up more than seven per cent at the time of Forbes’ report, following several successful launches within a 24-hour period.
Tesla shares also rose by around five per cent after the electric-vehicle company reported third-quarter deliveries of 486,532 vehicles, exceeding analysts’ expectations, according to the report.
The movements in both companies’ share prices contributed to the sharp increase in Musk’s estimated wealth.
Because a substantial portion of his fortune is tied to company equity and related assets, changes in share prices can produce large daily fluctuations in estimates of his net worth.
Nearing the trillion-dollar threshold
Musk remained at the top of Forbes’ real-time billionaire rankings in the report, with his estimated wealth approaching US$1 trillion.
The figure was an estimate taken at a specific time on October 2 and should not be treated as a fixed or cash-equivalent valuation. Billionaire rankings can change as market prices move and as valuation methods or assumptions are updated.
The reported rise also illustrates the influence of investor expectations surrounding major technology companies, including businesses operating in electric vehicles, space launches and satellite services.
Market valuations can change quickly
Tesla’s reported delivery figures provided one factor affecting investor sentiment, while SpaceX’s launch activity coincided with an increase in its share price.
However, a one-day rise in market value does not by itself establish a company’s long-term financial performance. Share prices can rise or fall as investors reassess business results, future prospects, market conditions and risks.
Musk’s reported US$61 billion gain therefore represents a change in estimated wealth tied to market valuations, rather than a realised cash gain of the same amount.
