great wealth transfer

An estimated US$124 trillion in wealth will change hands by 2048, according to Cerulli Associates — and roughly US$62 trillion of it, about half the total, will pass from high-net-worth and ultra-high-net-worth households that represent just 2% of all families. As this generational handover accelerates, a quieter shift is underway inside the family office: artificial intelligence is moving from back-office curiosity to a central tool in how the wealthy model, structure, and transfer their estates.

Key Takeaways

• Cerulli projects US$124 trillion in wealth will transfer through 2048, with high-net-worth and ultra-high-net-worth households accounting for roughly US$62 trillion — about half the total.
• AI adoption has reached 86% among large family businesses, according to Deloitte, though dedicated family-office use trails at around 22%.
• AI is increasingly applied to scenario modelling, tax and succession planning, and document-heavy estate administration.
• Next-generation heirs expect technology-driven, transparent and highly personalised wealth services.
• Human advisers, governance and data privacy remain decisive; AI augments fiduciary judgment rather than replacing it.

The Largest Wealth Transfer in History Meets Machine Intelligence

Cerulli Associates estimates that US$124 trillion will move between generations through 2048, with US$105 trillion flowing to heirs and US$18 trillion to charity. Crucially for private wealth, around US$62 trillion — half of all transfers — will originate from HNW and UHNW households, even though they make up only 2% of families. Baby boomers and older Americans alone are expected to pass on roughly US$79 trillion. The scale reflects a pandemic-era surge in asset prices, with equities and real estate climbing sharply between 2020 and 2023. For families navigating this handover, the planning challenge — tax exposure, succession structures, cross-border residency and philanthropy — has rarely been more complex.

Where AI Is Actually Being Deployed

Adoption is no longer experimental. Deloitte’s 2025 study of more than 1,500 large family businesses found an 86% AI adoption rate, with the leading use cases being process efficiency (40%), risk mitigation (39%) and client relationship management (39%). Among family offices specifically, uptake is lower but accelerating — roughly 22% now use AI for operational tasks or investment analysis, up from 13% a year earlier. In an estate-planning context, that translates into AI-assisted scenario modelling for trust and gifting structures, faster review of dense legal documentation, consolidated multi-entity reporting, and data-driven philanthropic planning. Just over half of family businesses (52%) report a fully integrated technology strategy, a prerequisite for deploying these tools at scale.

What This Means for HNWIs

For HNWIs and family offices, the practical priority is readiness rather than novelty. Begin by auditing data quality and integration, since AI is only as reliable as the records it draws on. Use AI to stress-test succession and tax scenarios across jurisdictions, but keep qualified legal and tax counsel firmly in the loop on every binding decision. Those weighing the broader picture should also revisit the technological transformation of wealth management, which laid many of the foundations now enabling AI-led estate planning. Above all, treat governance and data privacy as first-order concerns, not afterthoughts.

Family Office Adoption at a Glance

The gap between intent and capability defines the current market. While 86% of large family businesses report using AI and 68% cite productivity gains, only around one in five family offices have moved decisively into investment-grade applications. The most advanced offices pair AI tooling with a documented technology strategy and dedicated talent; the laggards risk handing a generational transfer to heirs who, surveys show, increasingly expect seamless, technology-native service. The differentiator is not access to models but the discipline to govern them.

Risks and Considerations

AI introduces real hazards in a fiduciary setting. Generative models can produce confident but inaccurate output — unacceptable when applied to tax or trust language. Data privacy is a particular flashpoint for ultra-wealthy families wary of exposing sensitive financial information to third-party systems. Over-reliance, cybersecurity exposure and an unsettled regulatory backdrop round out the risk picture. The prudent path treats AI as a supervised assistant whose work is always validated by experienced human advisers.

The Bottom Line

As US$124 trillion begins its move between generations, AI is becoming part of the estate-planning toolkit for HNWIs and family offices — but its value depends entirely on governance, data discipline and expert human oversight. The families who benefit most will be those who adopt deliberately, not reflexively.
