The hierarchy of the world’s wealthiest is shifting. This weekend, Donald Trump announced that he would escalate hostilities in Iran, a move that could exacerbate an already fragile situation for luxury giants. The world of billionaires is thus being turned upside down, with French billionaires feeling the impact firsthand.
The publication of the Forbes list in early March 2026 confirms this and thus proves to be a strong indicator of the upheavals underway in the global wealth hierarchy. Behind an apparent stability (more than 3,400 billionaires with a record combined net worth of $20.1 trillion), sectoral gaps are widening sharply. The case of Bernard Arnault is the most striking illustration of this: the LVMH CEO has seen his fortune decline by approximately $50 billion since the start of the year, penalized by the slowdown in the luxury sector.

He now ranks 8th on the Forbes list with an estimated fortune of $146 billion. Conversely, Elon Musk is solidifying his position at the top of the global rankings. His wealth is driven by the valuation of his technology assets, particularly in artificial intelligence, the automotive sector, and space exploration.
Elon Musk, at the Top of the Forbes Global Ranking
In a fragmented world, where digital power is a major asset for countries’ security and influence, these sectors now appear more strategic than ever, attracting public and private capital as well as political support. Between January 1 and early April, the South African-born billionaire’s fortune rose from $726 billion to $813 billion.
This divergence highlights a deep divide. The luxury sector, historically driven by globalization and the rise of the middle classes, depends on a climate of confidence and stability. Conversely, tech thrives in an uncertain environment, as it addresses issues of sovereignty, security, and power.
France’s major fortunes, heavily concentrated in luxury, thus appear more exposed than their American counterparts. This specialization heightens their vulnerability to external shocks.
The Rise of Fortunes Linked to AI Development
By 2026, fortunes will thus be built less on “desire capitalism”—that is, the economic model based on envy, dreams, and “aspirational consumption.” The economic system now places greater emphasis on what confers power in an uncertain geopolitical environment: technology, infrastructure, and artificial intelligence.
In the coming months, several trajectories remain possible. An escalation of international tensions could continue to weigh on the luxury sector and cause fortunes linked to AI development to grow exponentially. Conversely, a geopolitical de-escalation or a rebound in Asian consumption could quickly reverse the trend and restore balance.
The unpredictability of the Trump administration’s foreign policy strategy will nonetheless remain a factor that is likely to act as a constant brake on potential growth in the luxury sector.
Key Points:
• The hierarchy of major fortunes is shifting, with wealth moving from the luxury sector toward technology, as illustrated by Bernard Arnault’s decline relative to Elon Musk’s rise.
• In a tense international climate, sectors linked to power (technology, infrastructure) are favored, while those dependent on consumer confidence—such as luxury—are weakened.
• Artificial intelligence is emerging as a key driver of wealth creation by attracting massive investments and strategic support.
• France’s wealthiest individuals, whose fortunes are heavily concentrated in the luxury sector, appear more vulnerable to economic and geopolitical shocks than those with more diversified portfolios.
