Elon Musk has once again rewritten the record books, becoming the first person in history to surpass a $600 billion net worth.

According to Forbes, Musk’s fortune stood at an estimated $677 billion by midday Monday, a staggering leap powered primarily by a dramatic revaluation of his private aerospace giant SpaceX.

The surge follows SpaceX’s latest tender offer earlier this month, which valued the company at $800 billion—double its August 2025 valuation of $400 billion. Musk’s estimated 42% stake translates to roughly $336 billion, now his most valuable asset, eclipsing his Tesla holdings (about 12% stake worth $197 billion).

Additional boosts to Musk’s fortune include:

• xAI Holdings: Valued at $230 billion in ongoing funding rounds, with Musk’s ~53% share worth $60 billion.
• Tesla stock options: From his disputed 2018 performance award, conservatively valued at $69 billion pending a Delaware Supreme Court appeal.

The gap between Musk and the world’s second-richest individual, Google co-founder Larry Page, now stands at $425 billion—placing Musk closer to the $700 billion mark than losing his top spot.

Musk’s wealth trajectory has been meteoric. He crossed $100 billion in 2020, $200 billion in 2021, and briefly touched $300 billion later that year before volatility struck amid Tesla struggles and his Twitter acquisition. The rebound in 2025, driven by AI and space sector booms, has propelled him into unprecedented territory.

Analysts project Musk could become the world’s first trillionaire by 2026–2027 if SpaceX proceeds with a rumored IPO at a $1.5 trillion valuation and if xAI and Tesla sustain hyper-growth. Unlike many billionaires, Musk is known for eschewing superyachts and lavish estates, instead channeling his wealth into ventures such as Neuralink and The Boring Company.

The milestone underscores Musk’s dominance in transformative industries—electric vehicles, space exploration, and artificial intelligence—while reigniting debates about wealth concentration and inequality in a world where billions struggle with basic needs.
