Two bundles of cables going in different directions
2026 MIDYEAR INVESTMENT OUTLOOK

Scarcity vs. abundance

Could AI accelerate innovation and lift economic growth, ushering the world into a new era of abundance? Or will scarcity in power, labor, capital and materials dominate? Our 2026 Midyear Global Outlook looks at the big calls investors can’t avoid — and how the possibility of multiple, very different economic outcomes demand a portfolio rethink.

Investment themes

  • 01

    AI scarcity

    The AI buildout is accelerating, raising questions about bubbles, costs and who captures value. But whichever model wins, AI needs power, memory, chips and data centers — scarce inputs that are likely to shape investment opportunities.

  • 02

    Durable income

    Yields have reset higher globally, making income an opportunity again. The key is how investors earn it. We prefer short- and medium-term Treasuries and credit where income is supported by clear cash flows, lender protections and recovery values.

  • 03

    Beyond labels

    Investors may need to look beyond traditional asset-class labels to get the exposures they want. Thematic exposures don’t fit neatly into portfolio buckets: the same theme can appear across public and private markets, and across debt and equity. That makes the choice of vehicle part of the investment decision.

Scarcity now, abundance later?

We’re in a world of scarcity. Strengthening mega forces are putting increasing pressure on labor, energy, infrastructure, capital and materials. These supply-side constraints are shaping growth, inflation and market pricing. Meanwhile, AI raises the prospect of a permanent growth breakout by accelerating innovation itself. Yet the route to abundance, if we get there, runs through scarcity. A similar tension is playing out across other investment themes — and reshaping portfolios.

Investors face big macro calls that could lead to polyfurcated outcomes: multiple plausible paths and very different worlds. That means uncertainty across incompatible regimes, not just around a base case. Our Outlook focuses on six big calls: AI-led growth, AI cost, interest rates, debt, geopolitical chokepoints and U.S. leadership. Each contains competing narratives, and the calls are tightly linked: a view on one often implies a view on the others. Investors should understand which calls are embedded in their portfolios, size them deliberately and consider portfolio solutions that neutralize unwanted macro exposure.

Portfolio rethink needed

The new market dynamics are challenging the standard portfolio approach, and investors should think beyond asset-class labels.

Diversified exposure to the entire investable universe is a natural starting point for many portfolios. From there, investors can express views through deliberate exposures to themes and risks that cut across traditional asset classes. The final step is choosing the appropriate implementation vehicle, whether through active strategies, broad market indexes or subsets thereof, public or private markets, debt or equity, or other structures.

Granular approach raises potential payoff

Additional return with 20% more growth exposure than a 60/40 portfolio

The chart shows two sets of bars, one set shows the impact of adding 20% more exposure to economic growth by using an asset class approach, and the other shows the impact by using a granular lens.

These do not represent actual portfolios and do not constitute investment advice. The figures shown relate to simulated performance. Index returns do not reflect management fees, transaction costs or expenses. One cannot invest directly in an index.

Source: BlackRock Investment Institute with data from LSEG Datastream, June 2026. Note: The chart illustrates the hypothetical pickup in annualized returns from increasing a hypothetical 60/40 portfolio’s exposure to economic growth by 20% either by: upping allocation to U.S. equities by 20%, and getting that exposure by allocating to sectors with perfect foresight. Index proxies used are: MSCI USA for U.S. equities, Bloomberg US Treasury Index for U.S. bonds and S&P 500 Information Technology, Consumer Discretionary, Communication Services, Material, Financials, Health Care, Consumer Staples, Utilities, Industrials and Energy indexes for sectors. This analysis is done with the benefit of hindsight.

AI scarcity

The AI buildout is accelerating, bringing three unresolved questions into focus. First, is AI becoming a bubble? Outsized gains leave little room for disappointment, making earnings and margin delivery critical for U.S. equities. Second, how costly will AI be? Models may become cheaper and speed up adoption, yet we still do not have enough compute to meet demand. Third, who will capture the value? Model builders, cloud and chip providers, power and data-center owners may all capture part of the economics. AI could also create new pools of revenue beyond the technology sector, and we don’t yet know where those will accrue.

The answers to these questions depend in large part on the constraints that will shape AI costs, adoption and value capture.

Dispersion across the AI value chain

Total return ranges and averages in AI value-chain layers, 2023-26

The chart shows the total return range and averages of some custom AI equity baskets.

The figures shown relate to past performance. Past performance is not a reliable indicator of current or future results.

Source: BlackRock Investment Institute with data from Bloomberg, June 2026. Notes: Bars show the range between the highest and lowest three-year total returns within each AI value-chain layer; black markers show the average return. Hyperscalers are represented by Amazon, Alphabet, Meta and Microsoft. Data centres include data-centre operators, REITs and related service providers. Chips & semis include semiconductor companies only and exclude equipment manufacturers and design software firms. Software apps include enterprise AI software and AI productivity companies.

We seek broad exposure to the AI buildout through an overweight in U.S. equities. Even if the ultimate winners are unclear, many are likely to be found there. Second, we turn to active investing as returns diverge across the AI value chain, creating widening gaps between winners and losers. See the chart. Some opportunities sit outside the U.S., including EM and small caps. Third, we focus on AI scarcity. We do not need to know which AI model wins to know AI requires power, memory, chips and data-center infrastructure.

Durable income

We see higher interest rates as a defining feature of the new regime. With yields steadily resetting higher around the world, income is an opportunity again.

Scarcity keeps inflation sticky in both the long and short term, due to tight labor markets and demand for scarce resources. That makes the Fed less likely to cut rates soon. And markets have moved away from the rate-cut expectations that prevailed earlier this year.

Long bonds face an additional challenge. Heavy debt issuance and mounting debt loads mean investors are likely to demand a higher term premium — the extra yield for holding long-term bonds. They can still rally when stocks drop on concerns about the strength of consumption or bubble risk. But they no longer carry the ballast investors came to expect because of sticky inflation from supply shocks. This makes long bonds a risk that needs to be sized deliberately rather than treated as a default hedge. All this creates an opportunity in short- and medium-term Treasuries. They carry a much higher yield relative to volatility, as the chart shows.

Chart shows the risk-adjusted yields of selected fixed income.

The figure shown relates to past performance. Past performance is not a reliable indicator of future results. Index performance returns do not reflect any management fees, transaction costs or expenses. Indices are unmanaged and one cannot invest directly in an index.

Source: BlackRock Investment Institute with data from LSEG Datastream and Lincoln, June 2026. Note: Yield per unit of volatility is calculated as yield divided by the full-sample annualized standard deviation of monthly total returns for public market bonds and quarterly for private credit. Index proxies used: Bloomberg U.S. Treasury 1–3 Year Index for short-term U.S. Treasures, Bloomberg U.S. Treasury Non-Callable 10+ Year Index for Long-term U.S. Treasuries, JPMorgan GBI-EM Diversified for local-currency emerging market debt, and Lincoln Senior Debt for private credit.

We focus on credit where income is supported by clear cash flows, lender protections and recovery values across public and private markets. Infrastructure also belongs in the income toolkit as it offers regulated or contracted cash flows, often linked to inflation.

Beyond labels

In a world of scarcity, investors need to go beyond labels to get the exposures they want. Infrastructure is the clearest proof point: it sits at the intersection of AI demand, energy constraints and inflation-linked cash flows.

AI is increasing demand for data centers, power and grids. Geopolitical fragmentation is raising the value of domestic capacity, including ports.  And the energy transition requires new generation, storage and networks. Together, these forces give infrastructure exposure to scarce capacity, inflation-linked income and multiple mega forces simultaneously. But these thematic exposures don’t fit neatly into traditional portfolio buckets. The same exposure can appear across public and private markets and across debt and equity.

Raising infrastructure exposure

Hypothetical portfolio allocations to infrastructure

Source: BlackRock Investment Institute, Preqin, Bloomberg. January 2026. Note: The chart shows what recommended portfolio allocations to infrastructure could look like under various scenarios, with the two main variables being (1) the general level of illiquidity tolerance and therefore appetite for private assets, and (2) the willingness to take on deliberate infrastructure exposure over and above what is implicitly baked-in major asset classes.

Asset class implications

Key investment views

Our highest conviction views, June 2026

Driver What we think Portfolio expression
Growth and AI scarcity The AI buildout is speeding up, making bottlenecks binding. Overweight U.S. equities; focus on AI bottleneck opportunities: power, chips and data centers.
Duration and diversification Long bonds carry high rate sensitivity and are less reliable diversifiers. Prefer short- and medium-term government bonds over long bonds for income.
Credit spreads and liquidity Selectivity is crucial amid tight spreads and uneven fundamentals. Credit with clear cash flows, lender protections and recovery value; higher-rated high yield.
Inflation and  scarcity Scarcity, secure supply and power demand carry inflation risks. Infrastructure, energy bottlenecks, EM local debt and real-asset-linked exposures.
Alpha opportunity Wider dispersion and macro uncertainty raise value of active skill. Macro hedge funds, venture capital, market-neutral strategies, and selected private credit and non-U.S. alpha.
