Since we last took stock of the AI mega force in our 2026 Global Outlook, several shifts have increased our conviction that it’s even more powerful now. And some of those shifts give the U.S. a competitive edge on AI.

Title slide: A supercharged mega force

Since we last took stock of the AI mega force in our 2026 Global Outlook, several shifts have increased our conviction that it’s even more powerful now. And some of those shifts give the U.S. a competitive edge on AI.

1. AI spending accelerates

Spending for the AI buildout – already historic – is accelerating even faster than expected, especially for the 'hyperscalers' or mega cap tech companies leading the buildout. Just since October, their capital expenditure estimates out to 2030 are up 25%.

2. Energy and political constraints

In our outlook, we laid out three constraining forces on the buildout: physical, political and financial.

Firstly, physical. The spike in gas prices since the start of the Middle East conflict enhances the U.S. and China’s AI edge. Data centers in Europe and other parts of Asia rely on grids powered by Middle East gas. China relies on such grids only minimally and the U.S. is a net energy exporter.

3. Financing and market implications

The back-loaded revenue gains from the massive AI spend has seen companies take on more debt. Funding from private markets has also played a role. Some major IPOs for companies like OpenAI and Anthropic could test appetite in equity markets. But bond issuance from 'hyperscaler' tech companies has been well-absorbed. That depth of capital markets in the U.S. is another advantage in the AI theme.

Outro: Here’s our Market take

We stay overweight to U.S. and EM stocks after last week’s upgrade. We see larger-than-expected investment supercharging the AI mega force and focus on its beneficiaries.

A supercharged mega force

We view AI as a supercharged mega force as buildout spending is rising from already-historic levels, supporting our overweight U.S. and EM stocks.

Market backdrop

Oil fell as Iran pledged to open the Strait of Hormuz during the Lebanon ceasefire. Both the S&P 500 and the Nasdaq hit new record highs.

Week ahead

We watch global flash PMIs for signs of any growth drag, supply chain disruptions and price pressures from the Middle East conflict.

U.S.-Iran talks to end the Middle East conflict have boosted stocks to new record highs. Tech has helped drive the gains – and what’s becoming clearer is the building strength of the AI theme. Our conviction in the AI transformation grows as we see broad gains in revenues and already-historic capital spending even as U.S. tech valuations are back on par with the overall market. This reinforces our U.S. equity overweight and preference for AI thematic opportunities.

Even bigger spending
Hyperscaler capital spending consensus estimates, 2026-30

The chart shows that consensus estimates for hyperscaler mega cap tech company spending on AI is climbing from already-historic levels.

Equity markets have rebounded on hopes for a resolution to the Middle East conflict, with the S&P 500 hitting a new record high. Tech stocks and the AI theme have led the gains, with the U.S. tech sector up 11% so far this month. We are seeing broad improvements in the drivers of the AI theme across capital spending and revenues after a notable drop in valuations. First, we had already expected the fastest capital spending buildout in history as we laid out in our 2026 Global Outlook – and consensus expectations have only risen since then, with “hyperscaler” mega cap tech companies’ estimates for 2026 to 2030 up over 25% since October. See the chart. Second, we are seeing rapid revenue gains for some AI model builders. And third, U.S. tech valuations are now in line with the broader S&P 500 even as tech earnings expectations have risen sharply, as we noted last week.

In our 2026 Outlook, we identified three potential constraints on the AI buildout: power, politics and financing. The energy constraint is front and center and is starting to bind – but we have seen some improvements. “Behind the meter” power generation solutions – which generate power without a grid connection, help avoid potential delays from connecting to the grid and can limit impacts on local electricity prices – are set to move from being a marginal source to powering about 25-30% of new U.S. data centers in coming years, our compilation of equipment company estimates and Sightline Climate Data show. Yet supply disruptions from the Middle East conflict have caused a sharp spike in natural gas prices – a key source for powering AI data centers. The impact is regional in nature: Europe and larger Asian economies feel the disruptions more, while the U.S. is a net exporter with much lower prices. We think this, combined with “behind the meter” solutions, gives the U.S. an edge on AI. China’s diversified energy mix and nuclear and renewable energy leadership means it is also less affected.

Watching political constraints

On the U.S. political front, anti-AI data center sentiment is rising and creating pressures that could constrain the AI buildout. Maine’s legislature passed a temporary ban on large new data centers – a first among states in a new trend. At least 12 other states are looking to pause further AI data center building. We are monitoring the impact of these potential restrictions and their scale heading into U.S. elections later this year.

The AI buildout financing has played out as we explained in our Outlook’s leveraging up theme. Demand for bonds from hyperscalers has been strong, with an Amazon sale seeing demand quadruple the total amount sold. We view this leverage as necessary to get over the hump between front-loaded investment and backloaded revenues – and think it’s healthy so far. Upcoming new listings of key AI model builders and players will test this financing in equity markets. The rapid revenue gains of some model builders should be supportive, such as Claude model-maker Anthropic reporting a tripling of revenue to over $30 billion since the end of 2025. The depth of U.S. capital markets is another edge in the AI transformation.

Our bottom line

We stay overweight to U.S. and EM stocks, and see the AI mega force accelerating. Recent developments including energy disruptions reinforce the U.S. edge in AI. We also like AI thematic opportunities in power and infrastructure.

Market backdrop

Oil prices fell as Iran declared that the Strait of Hormuz would be open throughout the 10-day Lebanon ceasefire, ending the week at about $90. Both the S&P 500 and the Nasdaq hit record highs, with the latter posting its longest winning streak since 1992. Solid U.S. corporate earnings and a potential peace deal could buoy them further, in our view. U.S. 10-year Treasury yields dipped to 4.25%, but are still up more than 20 basis points since the conflict began.

We watch global flash PMIs for signs of any drag on growth from the supply chain disruptions tied to the Middle East conflict. We also watch Japan’s CPI and PPI to see if the Bank of Japan can look through conflict-driven cost pressures and stay on track to achieve 2% inflation by the end of 2027. UK unemployment hovers around its post-pandemic peak, so next week’s unemployment and inflation data – the first since the conflict began – will highlight the Bank of England’s inflation-growth trade-off.

Big calls

Our highest conviction views on six- to 12-month (tactical) and over five-year (strategic) horizons, April 2026

  Reasons
Tactical  
Favor AI beneficiaries We favor infrastructure and equipment supporting the AI buildout – like semiconductors, power and data center assets – that we think stand to benefit no matter the winners or losers. We see the AI theme lifting U.S. earnings, underpinning our U.S. equity overweight.
Select international exposures We like hard-currency EM debt on economic resilience, disciplined fiscal and monetary policy and a high ratio of commodities exporters. We like EM equities too, preferring commodity exporters and AI beneficiaries. In Europe, we favor equity sectors like infrastructure.
Evolving diversifiers We suggest looking for a “plan B” portfolio hedge as long-term U.S. Treasuries no longer provide portfolio ballast. We like gold as a tactical play with idiosyncratic drivers, but we think it has become more unreliable as the diversification mirage grows.
Strategic  
Portfolio construction We favor a scenario-based approach as AI winners and losers emerge. We lean on private markets and hedge funds for idiosyncratic return and to anchor portfolios in mega forces.
Infrastructure equity and private credit We find infrastructure equity valuations attractive and mega forces underpinning structural demand. We still like private credit but see dispersion ahead – highlighting the importance of manager selection.
Beyond market-cap benchmarks We get granular in public markets. We favor DM government bonds outside the U.S. Within equities, we favor EM over DM yet get selective in both. In EM, we like India which sits at the intersection of mega forces. In DM, we like Japan as mild inflation and corporate reforms brighten the outlook.
