Largest BlackRock alternative asset funds worldwide in June 2026, by net assets

Leading alternative asset funds owned by BlackRock globally as of June 17, 2026, by net assets under management

BlackRock is the worlds largest asset manager, and in recent years it has pushed hard into alternative assets such as private credit, infrastructure and real estate. This report ranks the largest BlackRock alternative asset funds worldwide in June 2026 by net assets, a business built largely through major acquisitions. Global Infrastructure Partners was founded in 2006 and HPS Investment Partners traces its roots to the early 2000s, yet both became part of BlackRock only recently, instantly turning the firm into one of the largest alternatives managers in the world.

At the top sit the firm flagship infrastructure funds and its biggest private credit vehicle, each around 25 billion dollars. This sits alongside our largest BlackRock equity mutual funds ranking and our largest BlackRock equity ETFs analysis, completing the picture across the firm fund range.

A few giants on top: the HPS Corporate Lending Fund and the Global Infrastructure Partners flagship funds lead, each around 25 billion dollars, well ahead of the smaller real estate and credit funds further down the list.

BlackRock alternatives business grew enormously after it bought Global Infrastructure Partners in 2024 and the private credit manager HPS Investment Partners in 2025, deals detailed in our BlackRock acquisitions overview.

A note on the data. Alternative funds report size in different ways, mixing committed capital, fund net asset value and assets under management, so the figures here are approximate and not strictly comparable. They are drawn from BlackRock, GIP and HPS disclosures and industry data. Private funds also draw down capital over time, so a fund can have large commitments but a smaller amount actually invested at any moment, another reason the figures here are presented as careful approximations rather than precise, comparable numbers.

How BlackRock Built Its Alternatives Platform

BlackRock did not build its alternatives platform slowly. It assembled around 450 billion dollars in alternative assets largely by acquisition, buying Global Infrastructure Partners in 2024 and the private credit manager HPS in 2025, then adding smaller deals on top. For perspective, BlackRock manages around 14 trillion dollars in total, of which roughly two thirds sits in low-cost index strategies, so even a 450 billion dollar alternatives platform is a small fraction of the firm, despite being one of the largest of its kind.

Each acquisition added a large block of assets at once. GIP brought a major infrastructure business, HPS brought private credit, and ElmTree added net-lease real estate, together transforming a modest platform into one of the largest in the world, as our BlackRock AUM by asset class breakdown shows.

Built by deals: the waterfall shows how the platform reached around 450 billion dollars, with the GIP and HPS acquisitions adding the two biggest blocks, alongside ElmTree, other deals and market growth.

The contrast shows why BlackRock has pushed so hard into private markets. Alternatives are a small slice of its assets but a large source of fee income, which is why it spent more than 25 billion dollars buying its way into infrastructure and private credit. The economics explain the strategy: a private credit or infrastructure fund can earn many times the fee of an index ETF on each dollar, so even a modest share of assets in alternatives can contribute an outsized share of the firm fee revenue and profit growth.

Largest BlackRock Alternative Asset Funds by Net Assets

The table lists the largest BlackRock alternative asset funds by size in 2026, with each fund as a share of the top ten total. It shows how the flagship infrastructure and private credit funds dominate, while real estate funds are smaller. Sorting any column reveals the full order. The flagship Global Infrastructure Partners funds and the HPS Corporate Lending Fund are the anchors of the list, each holding more than 20 billion dollars, while the remaining real estate and smaller credit funds hold only single-digit billions apiece.

Largest BlackRock Alternative Funds by Asset Class

By asset class, the largest BlackRock alternative funds split into three main groups: infrastructure, private credit and real estate. Infrastructure leads, powered by the Global Infrastructure Partners flagship funds, followed by private credit and then real estate. Infrastructure covers energy, transport, digital infrastructure such as data centres and fibre, and water and waste, while private credit lends directly to companies and real estate spans property equity and debt, giving the platform exposure across very different private markets.

The infrastructure funds come from Global Infrastructure Partners, bought in 2024, while the private credit funds come largely from HPS Investment Partners, bought in 2025. The real estate funds, including the net-lease specialist ElmTree, are covered in our BlackRock real estate holdings overview.

Infrastructure first: among the top ten funds, infrastructure holds the most assets, powered by the Global Infrastructure Partners funds, followed by private credit from HPS and then real estate.

This mix reflects where BlackRock saw the biggest opportunities. Infrastructure and private credit are forecast to be among the fastest-growing parts of private markets, which is why the firm built its alternatives platform around those two areas through large acquisitions. In 2025 BlackRock, GIP, Microsoft and the technology investor MGX launched a partnership aiming to mobilise up to 100 billion dollars for data centres and power, a sign of how central infrastructure has become to the firm vision of where private capital will flow next.

The Newest Funds Are the Biggest

The largest alternative funds vary widely in age and structure. Some are recent vintages raised in the past few years, while others, such as the older infrastructure funds, date back to the 2010s but remain large as they continue to hold and manage assets. The HPS Corporate Lending Fund, a non-traded business development company, reported more than 23 billion dollars of investments at fair value in 2025, making it one of the largest private credit vehicles of its kind anywhere in the market.

Plotting each fund size against its vintage shows that the biggest funds are mostly recent, reflecting how quickly private markets have grown. The newest infrastructure and private credit funds are the largest, a trend tracked across our leading fund managers ranking.

Newest are biggest: each bubble is a fund, placed by vintage and size. The largest funds are mostly recent, reflecting how fast private credit and infrastructure have grown over the past few years.

This pattern shows the momentum behind private markets. Each new flagship fund tends to be larger than the last, as investors pour money into infrastructure and private credit in search of higher yields and returns that do not move in step with public stock markets, a search for yield reflected across our leading BlackRock funds by NAV return analysis. Private credit and infrastructure have boomed as investors hunt for income and inflation protection, with the wider private credit market alone estimated at around 2.2 trillion dollars, of which retail wealth vehicles such as business development companies make up roughly 550 billion.

How the GIP Flagship Funds Have Grown

The Global Infrastructure Partners flagship funds have grown with each vintage. From around 5.6 billion dollars in the first fund to 25.2 billion in the fifth, each fund has been larger than the one before, building a powerful infrastructure franchise. The first GIP fund raised around 5.6 billion dollars in 2006, with founding investors including Credit Suisse and General Electric, and the funds have grown with nearly every vintage to reach 25.2 billion dollars by the fifth, one of the largest infrastructure funds ever closed.

Taken together, the GIP flagship funds have raised well over 70 billion dollars across five vintages, making them among the largest infrastructure funds in the world. This steady growth is part of why BlackRock paid so much to acquire the firm, as our BlackRock assets under management overview explains.

Growing every vintage: the bars show each GIP flagship fund size and the line shows the cumulative total. From 5.6 billion dollars in the first fund to 25.2 billion in the fifth, each has been larger than the last.

The rising fund sizes show how infrastructure has moved from a niche to a mainstream asset class. Demand for investment in energy, transport, digital infrastructure and water has surged, and the GIP funds have grown to meet it, fund after fund. GIP portfolio companies have included major airports such as Gatwick and Edinburgh, alongside ports, pipelines and power assets, and together they employ around a hundred thousand people, underlining the scale and real-world reach of the infrastructure the funds own.

How Acquisitions Built the Platform

BlackRock alternatives assets jumped sharply after its two big acquisitions. Comparing 2024 with 2026 shows private credit and infrastructure assets multiplying, driven not by slow organic growth but by buying established managers outright. The leap was driven by acquisitions rather than slow fundraising: BlackRock bought GIP in 2024 and HPS in 2025 for more than 25 billion dollars combined, and also acquired the data provider Preqin and the net-lease real estate specialist ElmTree to round out the platform.

Private credit assets rose from around 38 billion dollars at the end of 2024 to around 203 billion by the end of 2025, after the HPS deal, while infrastructure assets climbed past 189 billion. This acquisition-led leap is tracked through the firm risk platform in our BlackRock Aladdin platform overview.

An acquisition leap: comparing 2024 with 2026, private credit assets jumped from around 38 to 203 billion dollars after the HPS deal, while infrastructure and the total platform also climbed sharply.

The pattern shows a deliberate strategy: rather than build private markets slowly from scratch, BlackRock bought its way to scale, acquiring GIP and HPS to become one of the five largest alternatives managers in the world almost overnight. By the end of 2025 the combined private credit franchise held around 220 billion dollars in client assets, while infrastructure assets under management reached around 189 billion, figures that would have taken many years to build organically from a standing start.

How Concentrated the Assets Are

BlackRock largest alternative funds are concentrated at the top. The biggest private credit and infrastructure funds, each around 25 billion dollars, together make up a large share of the top ten, while the smaller funds trail well behind. The top funds are so large because flagship private credit and infrastructure vehicles attract enormous single commitments from pension funds, insurers and sovereign wealth funds, which prefer to write large cheques to a few trusted managers rather than spread money thinly.

This concentration shows how a few flagship funds anchor the platform. The HPS private credit fund and the GIP infrastructure funds carry most of the weight, a pattern that echoes the wider fund industry covered in our number of BlackRock funds overview.

Top-heavy: the two biggest funds alone make up around 40 percent of the top ten, and the top three more than half. A handful of flagship funds anchor the whole platform.

The result is that BlackRock alternatives business rests on a handful of very large funds. Outside the top few, the funds are far smaller, underlining how much the platform depends on its flagship infrastructure and private credit vehicles. Several smaller funds on the list, including the real estate and infrastructure credit vehicles, hold only a few billion dollars each, modest by the standards of a firm of BlackRock size and a reminder that the platform leans heavily on its handful of giant funds.

The Whole Alternatives Platform by Type

Grouping the top funds by asset class shows where the money sits. Infrastructure holds the most, led by the Global Infrastructure Partners funds, followed by private credit from HPS and BlackRock direct lending, then real estate. Across the whole platform, private credit and infrastructure are by far the largest pieces, at around 203 billion and 189 billion dollars respectively, with real estate, private equity and hedge fund strategies making up the smaller remainder of the alternatives business.

The strength of infrastructure reflects the scale of the GIP funds, while private credit shows the impact of the HPS acquisition. Real estate, though smaller, remains an important part of the mix, as our asset manager statistics overview describes.

A lopsided profile: across the five main types, private credit and infrastructure dominate at around 203 and 189 billion dollars, while real estate, private equity and hedge funds are much smaller.

This segment view captures both the concentration and the breadth of the platform. Infrastructure and private credit dominate, but BlackRock runs sizable funds across real estate and other private markets, giving it a broad alternatives franchise. BlackRock also runs liquid alternatives and systematic hedge fund strategies, which saw steady retail inflows in 2026, showing that the platform spans both illiquid private funds and more liquid vehicles that ordinary investors can more easily buy and sell.

The Rise of the Alternatives Platform

BlackRock alternatives platform has grown rapidly, mostly through acquisitions. From around 120 billion dollars in 2020, total alternative assets climbed past 450 billion by 2026, with the biggest jumps coming after the GIP and HPS deals. The platform growth came in steps rather than a smooth curve, with the sharpest jumps in 2024 and 2025 as the GIP and HPS deals closed, each adding a large block of assets and capabilities to the firm in a single transaction.

The sharp rises in 2024 and 2025 mark the GIP and HPS acquisitions, which added infrastructure and private credit assets at a stroke. This rapid, deal-driven growth stands in contrast to the slower path of the firm older businesses, as our BlackRock AUM by asset class analysis shows.

Built by deals: the platform grew from around 120 billion dollars in 2020 to more than 450 billion by 2026, with the sharpest jumps in 2024 and 2025 as the GIP and HPS acquisitions closed.

The platform steep climb shows how seriously BlackRock has taken private markets. In just a few years it has gone from a modest alternatives player to one of the largest in the world, reshaping its business around higher-fee private assets. BlackRock chief executive Larry Fink has repeatedly described private markets as central to the firm future, arguing that the line between public and private investing is blurring and that clients increasingly want both inside a single portfolio managed by one provider.

The Cost of Private Markets

The defining feature of these funds is that they charge far higher fees than index products. Alternative funds typically charge management fees of around 1 to 2 percent plus a share of profits, against just 0.03 percent on the largest iShares ETF. A typical private fund charges a management fee of around 1 to 2 percent of assets each year, far above the roughly 0.03 percent on the largest index ETFs, and many also keep a performance fee, leaving investors with a much higher total cost for active private exposure.

Private credit and infrastructure funds often charge a performance fee, or carried interest, of around 20 percent of gains above a hurdle, on top of the management fee. These rich economics are why BlackRock pushed into alternatives, as our largest asset managers coverage notes.

The two and twenty load: private funds stack a management fee of around 1 to 1.5 percent on top of a performance fee, so total annual costs can reach 2 to over 3 percent, many times the fee on an index ETF.

These higher fees are the price of access to private, less liquid assets that aim for higher returns. For BlackRock, they make alternatives far more profitable per dollar than index funds, even though the alternatives platform is a small share of total assets. Even after these fees, investors have flocked to alternatives in search of returns above public markets and income that does not move in step with stocks and bonds, which is why BlackRock and its rivals have competed so fiercely to build private markets scale.

Big Funds in a Bigger Firm

Even the largest BlackRock alternative funds are modest next to its index business. The biggest, at around 25 billion dollars, is large for a private fund, but the firm largest equity ETF holds around 800 billion, more than thirty times as much. The contrast is stark: the entire alternatives platform, at around 450 billion dollars, is smaller than a single one of the firm largest index ETFs, yet it generates a far larger share of fees, which is precisely why BlackRock has invested so heavily to build it.

This matters because it shows the different roles the businesses play. The index ETFs provide vast scale at low cost, while the alternative funds provide high fees and growth, a balance our asset management overview coverage underlines.

Size and strategy go together here. The alternative funds are smaller because private markets are less liquid and harder to scale, but they are far more profitable per dollar, which is exactly why BlackRock has invested so heavily in building them. Private markets are also harder to scale because deals take time to source and capital is committed for years, so alternatives will likely always be smaller than index funds in asset terms even as they grow into a much larger share of the firm overall revenue.

Largest BlackRock Alternative Funds: The Big Picture

Taken together, the largest BlackRock alternative funds show a clear pattern: a few flagship infrastructure and private credit funds dominate, each around 25 billion dollars, built largely through acquisitions rather than slow organic growth. The ranking also shows how quickly the alternatives landscape can shift, with a firm that was a modest private markets player only a few years ago now sitting among the five largest alternatives managers in the world, almost entirely through bold, expensive acquisitions.

These funds are central to BlackRock push into private markets, even though they are a small share of its total assets. The contrast with the trillion-dollar iShares range is stark, a divide also seen across our iShares ETF coverage.

For BlackRock, alternatives are a growth engine rather than a legacy. They serve investors seeking higher returns and income from private assets, and they generate far higher fees than index funds, which is why the firm has made them a strategic priority.

Taken together, the data shows that BlackRock alternative fund assets are concentrated in a few flagship funds, led by its biggest private credit and infrastructure vehicles at around 25 billion dollars each. Real estate and smaller credit funds fill out the rest of the top ten, with the firm multi-asset range covered in our leading BlackRock multi-asset funds report.

Whether measured by size, growth or fees, the largest BlackRock alternative funds tell the same story: a fast-growing, acquisition-built private markets business that has propelled the firm into the top ranks of global alternatives. From flagship infrastructure funds to a giant private credit vehicle, the platform now stands among the market leaders tracked in our biggest companies by market value overview.
