Family offices across the Americas are adding to infrastructure and private equity while holding steady on private credit, according to a BlackRock survey that points to a widening split between newer and long-established offices in how they approach alternative investments. The asset manager polled 206 single-family offices in the U.S., Canada and Latin America between July and August, working with its data unit Preqin. The respondents collectively oversaw an estimated $491 billion in investable assets.
Infrastructure showed stronger momentum than any other alternative asset class. Thirty percent of respondents said they plan to raise infrastructure allocations over the next 12 months, and just 6% plan cuts. BlackRock said the 24-percentage-point gap was the widest of any alternative it measured.
Younger offices, which BlackRock defined as offices founded less than 20 years ago, are behind most of that demand. Among them, 38% expect to increase infrastructure exposure, compared with 16% of offices more than two decades old. Newer offices also hold more already: 11% reported infrastructure allocations between 6% and 15%, and no older office in the sample reported an allocation that large. The report argues that gap comes down to a matter of timing. Infrastructure has emerged as a mainstream investable asset class only over roughly the past 20 years, so older offices built their illiquid portfolios around a different set of opportunities.
Respondents most often cited diversification (32%), inflation hedging (26%) and low correlation with other assets (20%) as their reasons for investing. The appetite BlackRock saw contrasts with findings earlier this year in J.P. Morgan Private Bank's 2026 global family office report, where 79% of family offices had no exposure to infrastructure despite its role in supporting data centers, energy demand and digital networks tied to AI expansion.
Private equity remains the anchor of family office alternatives portfolios. A little more than half of respondents (52%) put more than 15% of their alternatives allocation in the asset class. Another 32% plan to add over the next year, up from 26% in BlackRock's 2025 global family office survey. The two generations of offices take different routes into private equity. Among newer offices, 45% named secondaries as a preferred route, compared with 28% of older ones. BlackRock reads this as a way to build positions quickly while limiting J-curve exposure. Established offices lean more on co-investments, at 75% against 60% for newer offices.
The offices building infrastructure positions today are the ones that wrote down a deployment pace before they wrote the first check, family office advisor Jaf Glazer has observed.
The optimism has limits. About three-quarters of respondents (76%) cited the exit environment as a main obstacle to private equity returns over the next 12 months, and half pointed to valuations. Private credit is the exception. Nearly half of respondents (49%) plan to keep allocations where they are, with 17% planning increases and 15% planning cuts. That is a cooler reading than a year earlier, when private credit topped the wish list.
Liquidity is the main constraint across private markets. Illiquidity was the top barrier to allocating more, cited by 54% of respondents. Access to top-tier managers (39%) and fees (36%) followed. Only 16% are reducing private capital exposure because of their view of the market cycle, and 48% say they are not changing allocations at all. Respondents expect to fund new commitments mainly from distributions on existing private funds and from cash on hand, rather than by selling public holdings. "Newer offices are approaching private markets and liquidity differently than their more established peers, reinforcing the importance of balancing investment opportunities with each family's unique cash-flow needs, constraints and long-term objectives," said Armando Senra, head of the Americas institutional business at BlackRock.
