The AI revolution has unleashed a $1.8 trillion windfall for global billionaires, propelling their collective wealth by a staggering 25 per cent in 2025 alone. This monumental growth spurt, driven by tech-driven market rallies and the emergence of new billionaires, now sees nearly 400 new entrants to the billionaire club worldwide, according to UBS's latest analysis. Meanwhile, average UK household wealth has been steadily eroded over the same period.
The numbers tell a stark tale: total billionaire wealth surged ahead by 13 per cent year-on-year, dwarfing the 10.8 per cent rise in global average wealth. This chasm is largely attributed to super-rich investors' significant stakes in burgeoning AI and technology sectors. Notably, Elon Musk's SpaceX IPO briefly catapulted him into trillionaire territory, valuing the rocket maker at a record-breaking $1.8 trillion on its market debut – although this status was fleeting.
The UK, however, has been largely left out of this wealth bonanza. The UBS report warns that British residents have suffered the largest decline in overall wealth levels since the pandemic among developed economies. Average household wealth has declined by over a fifth in real terms over the past five years, surpassing all other 36 countries assessed by the bank – despite some facing severe economic challenges.
A key factor behind the UK's dwindling wealth is its reliance on property holdings, which have largely failed to keep pace with rising living costs and above-target inflation. In fact, billionaire wealth within Britain itself is also in decline, as evidenced by the Sunday Times Rich List's findings that one in six individuals featured in 2024's edition were absent from this year's list due to reportedly relocating to jurisdictions with lower tax rates.
