Global AUM Growth and 2030 Outlook
The industry’s two most-cited surveys tell the same growth story from slightly different anchor points:
- Boston Consulting Group puts global assets under management at $147 trillion in 2025 and notes that more than 80% of revenue growth came from market performance.
- PwC anchors the industry at $139 trillion in 2024 and projects it will reach $200 trillion by 2030 at a 6.2% compound annual rate.
- Total investable wealth worldwide is expected to exceed $481 trillion by 2030.
The gap between total investable wealth and AUM is the retail-plus-defined-contribution runway that BCG points to as the industry’s most reliable source of new assets over the next five years.
Recent Developments

Active vs Passive: The Flow Story
The active-versus-passive scoreboard tells three data-points-at-once story:
- Passive strategies now account for 39.0% of the top-500 total, a 6.1% increase in share.
- At year-end 2025, index mutual funds and index ETFs combined for the majority, 52%, of long-term US fund assets, with ETF net share issuance of $1.5 trillion in 2025 while mutual funds saw net outflows of $552 billion.
- US-listed ETFs added over $1.3 trillion in net inflows through early December 2025, already past 2024’s record, with Q4 alone contributing $341 billion.
- A record 1,000+ new ETFs launched in 2025 for the first time, and 84% of the year’s new products were actively managed.
The reconciliation is straightforward: Active launches cluster in fixed income and thematic slots that carry higher fees while broad-market beta concentrates in the largest index shops. Active fixed-income ETFs captured a record 38% of total FI inflows in 2025, taking in $146 billion.
Is active or passive investing winning?
Passive holds 39.0% of top-500 AUM while 84% of the new US ETFs launched in 2025 were actively managed. Both trends can hold at once; the passive core keeps growing while active competes on the margin.
Private Markets and the 2030 Revenue Mix
The revenue-mix shift is where the industry’s forward story lives:
- PwC projects private markets revenue at $432.2 billion by 2030, growing at an 8.2% compound annual rate and delivering more than half of total asset management industry revenues.
- Passive AUM is projected to rise at a 10% compound annual rate, reaching $70 trillion by 2030.
- Tokenised fund AUM is projected to grow from $90 billion in 2024 to $715 billion by 2030 at a 41% CAGR (per the same PwC dataset).
Private-market AUM stays a minority of the total pool even by 2030, but the fee-per-dollar arithmetic means the revenue split flips first.
BCG projects that the value of tokenized real-world assets will reach $14 trillion by 2030 and $55 trillion by 2035. That trajectory is one of the largest cross-industry runways for asset managers. The Private equity segment pulls the largest share of that alternatives budget.
AUM ≠ investment recommendation: These AUM figures describe industry scale, not endorsement of any specific product or manager. Regulatory disclosures, expense ratios, and manager selection remain the reader’s job; CoinLaw is informational only.
US Industry Composition
The US market is where the industry earns its “global” label:
- At year-end 2025, US-registered investment companies held $45.1 trillion in total net assets, with mutual funds at $31.4 trillion and ETFs at $13.4 trillion.
- Index mutual funds and index ETFs together accounted for 52% of long-term fund assets at year-end 2025.
| US registered investment company assets | Year-end 2025 |
|---|---|
| Total net assets | $45.1 trillion |
| Mutual funds | $31.4 trillion |
| Exchange-traded funds | $13.4 trillion |
| Index share of long-term funds | 52% |
| ETF net share issuance (2025) | $1.5 trillion |
| Mutual fund net outflows (2025) | $552 billion |

Regional concentration reads through cleanly at the manager level:
- 15 US managers make up the top 20 by AUM, accounting for 83.9% of the top-20 pool, with the remaining five slots held by European firms.
- North America accounted for $88.2 trillion, or 63%, of top-500 AUM at the end of 2024, with regional AUM growing 13% year over year.
Japan’s managers saw their AUM decline 9.5% in 2024, a significant regional pullback among the top-500 constituents. The gap between North America and everyone else widened again in 2024, reversing several years of directional convergence.
AUM vs AUA: Fidelity’s headline $17.9 trillion figure is Assets Under Administration, while its Managed Assets number (formerly called Discretionary Assets) was $7.0 trillion at March 31, 2026. The two definitions leak into industry copy interchangeably, and the difference matters when comparing firms to peers that report AUM.
AI, Costs, and Where Margins Are Going
Industry cost structures are the next chapter:
- BCG estimates asset managers could reduce costs by 25% to 35% over the next three to five years by applying AI across research and client coverage.
- Industry profit margins have stayed broadly flat at around 30%.
Read those two numbers together as a margin-defense budget, not a growth budget: the AI cost-out ratchet is the industry’s primary tool to hold margin when a market cycle turns.
Applied machine learning work in the compliance and coverage layer is the most visible category to date; back-office cost programs sit alongside it.
Key finding: BCG’s 25% to 35% cost-out band is available to the industry in the same window that market-performance revenue growth stalls, meaning the tool arrives when it will be most needed.
Who is the largest asset management firm in the world?
BlackRock ended Q1 2026 with Assets Under Management of $13.9 trillion at March 31, 2026, and has held the top slot since 2009. Vanguard reports more than 50 million investors worldwide as of December 31, 2025, and Fidelity reports $7.0 trillion in Managed Assets and $17.9 trillion in Assets Under Administration at March 31, 2026.
How much AUM will private markets manage by 2030?
Private-markets AUM stays a minority of the industry pool by 2030, but the revenue share flips first. PwC’s baseline projects industry-wide AUM at $200 trillion by 2030 with private markets revenue of $432.2 billion, more than half of total industry revenue.
Conclusion
Global assets under management crossed $147 trillion in 2025 and are projected to reach $200 trillion by 2030, but the underlying story is concentration rather than pure growth. Twenty firms already control 47.0% of top-500 AUM, and 15 US managers make up 83.9% of that top-20 pool; the top ten passive providers took more than 90% of net inflows across the past decade.
The passive share continues to climb, active product finds intake at the fixed-income and thematic ends of the shelf, and AI-driven cost-out is the primary lever managers have to defend margin. BCG’s cost-out band of 25% to 35% on the AI side lands during a period when profit margins have stayed roughly flat at 30%.
