According to the Bloomberg Billionaires Index, on 5 October 2026, Elon Musk’s fortune once again exceeded $1 trillion, reaching $1.04 trillion. Over the course of the day, the estimated value of his assets rose by approximately $65 billion, driven by gains in the share prices of SpaceX and Tesla.
Briefly about the main points
- Bloomberg estimated Musk’s net worth at $1.04 trillion as at 5 October.
- Over the course of the day, the estimated value of his capital rose by approximately $65 billion.
- Musk’s assets in SpaceX and Tesla account for over 98% of the valuation.
- SpaceX has rebounded by approximately 58% from its August low.
Market valuation, not the money in the accounts
The Bloomberg Billionaires Index reflects the estimated value of an entrepreneur’s assets at current market prices. Over 98% of this valuation is attributable to his assets in SpaceX and Tesla, so fluctuations in these companies’ share prices can cause their market capitalisation to shift by tens of billions of dollars in a single trading session.
The current return to above the one-trillion mark came roughly three months after the first such figure was recorded. In June Elon Musk It crossed this threshold for the first time following SpaceX’s flotation.
SpaceX’s recovery following its IPO
Pros. data According to Bloomberg, SpaceX shares have risen by approximately 13% since the start of October and have recovered by around 58% from their August low. Earlier, following the company’s stock market debut, Musk’s net worth had fallen by more than $600 billion from its peak.
SpaceX IPO took place on 11–12 June 2026. The placement raised approximately $75 billion and valued the company at $1.77 trillion at the IPO price, whilst its market capitalisation exceeded $2 trillion following the start of trading.
Analysts at Morgan Stanley have highlighted SpaceX’s potential in the space sector, satellite communications and AI. Following its merger with xAI, the company’s business now encompasses space launches, Starlink and artificial intelligence; its consolidated revenue for 2025 stood at $18.67 billion, whilst the company remained loss-making.
Tesla’s contribution to the return to one trillion
Tesla’s share price has risen by 6.7% since the start of October. On 2 October, the company announced that it had delivered 486,532 vehicles and produced 464,391 in the third quarter of 2026.
A separate indicator of demand was the rise in Tesla registrations in Europe in September: in France, they increased by 61.9% year-on-year; in Sweden, by 38.4%; and in Spain by 24.8%. Registrations are not identical to global deliveries, but they reflect trends in individual markets.
As the valuation of Musk’s wealth depends largely on the value of his shareholdings in SpaceX and Tesla, his trillionaire status could change again in line with fluctuations in their share prices — without him having to sell any of these assets.
