A brighter productivity outlook for the AI era
In brief
- We believe artificial intelligence (AI) will drive a meaningful, durable uplift to productivity over our 10- to 15-year forecast horizon, adding to our growth and return expectations.
- We have incrementally incorporated AI’s potential into our Long-Term Capital Market Assumptions since 2023, but the dramatic acceleration in capabilities and investment now requires more sophisticated analysis. This year, we have rebuilt our methodology to capture both the efficiency gains from scaling AI and the capital deepening required to deploy it.
- AI adoption remains early and uneven. Only 6% of U.S. work hours are AI-assisted today, even as two-thirds of tasks may be theoretically exposed. We expect adoption to reach 40% of today’s tasks by 2040 as AI shifts to more agentic, and even robotic, workflows and spreads from knowledge-intensive industries to routine work across sectors.
- Our base case estimates that AI will boost U.S. total factor productivity (TFP) growth by roughly 40 basis points (bps) above the pre-AI norm, to 1.2% annually, and lift U.S. capital stock growth by about 30bps, to 2.3% per year. Together, these gains raise our U.S. labor productivity forecast by 50bps over the same period, to 2.2%. In our forecast, improved productivity is the main force behind U.S. GDP growth returning to a 2%-plus pace over the coming decade.
- The pace of AI diffusion and the resulting productivity boost are likely to be gradual, with the most significant gains emerging in the 2030s and beyond. This is an important premise of our macroeconomic and asset class assumptions. Steady uptake should limit rapid, economy-wide job displacement while giving supply chains time to adapt.
- The U.S. looks well positioned to lead AI adoption. It registers the largest AI-driven TFP increase in our forecast universe, reflecting the economy’s robust technology ecosystem and supportive institutions. Europe, Asia and emerging markets stand to see material benefits while facing varying constraints based on industry mix, regulation, infrastructure and cultural and workplace norms.
- We don’t think markets fully appreciate the economy-wide potential of AI, but selectivity and thoughtful diversification are key to investing in this space. We believe portfolios can best capture AI’s opportunity by balancing exposure across the AI value chain and funding cycle, spanning public and private markets.
AI’s promise is becoming real. As the technology races forward, trillions of dollars are flowing into semiconductors, data centers and power suppliers – the new AI ecosystem. But will AI make the economy more productive and, if so, by how much, how quickly and for whom?
No force has a greater impact on our Long-Term Capital Market Assumptions (LTCMAs) than productivity growth, the pace at which an economy turns its labor and capital into more output. Productivity underpins economic growth, living standards, corporate earnings, inflation and interest rates. As the economist Paul Krugman once said, “Productivity isn’t everything, but in the long run, it is almost everything.”
We believe AI will raise productivity meaningfully and durably over our 10- to 15-year horizon, reshaping the nature of work and patterns of investment. While we have incrementally incorporated AI’s potential into our LTCMAs since 2023, the dramatic acceleration in capabilities and investment now requires more sophisticated analysis. To capture that shift, we have rebuilt our AI methodology and embedded it within our macroeconomic building blocks. Anchored around a Cobb-Douglas production function, it attributes an economy’s output to its labor and capital, and how efficiently those are used (see Methodology Handbook).
In that framework, AI lifts labor productivity, measured as output per hour worked, through two channels. First, it makes existing work more efficient, enabling the same people and machines to produce more (total factor productivity, or TFP). Second, it equips workers with improved tools, systems and infrastructure as investment scales (capital deepening).[1] Here, we present our new methodology and the insight it delivers.
AI capability has outrun adoption

Building our LTCMA base case
What might lie ahead? Forecasting productivity is difficult even in ordinary times, and profound technological change makes the challenge even greater. Our updated methodology should offer a solid framework from which to reason and refine as new evidence develops.
For total factor productivity, we focus on the specific tasks AI can perform, and how efficiently. We then map those gains across the economy, an approach grounded in Hulten’s theorem as applied by Daron Acemoglu and others.[6] We estimate capital deepening by projecting how AI-related investment affects the economy’s productive capital stock, net of depreciation and “crowding out” (displacing other productive investments).
By 2040, we believe, AI adoption will have shifted to more embedded agentic,[7] and even robotic, workflows, spreading beyond knowledge-intensive early users to routine work across sectors.
But diffusion will be gradual. We expect a slow start, with adoption accelerating in the early 2030s and then tapering as remaining use cases become harder or less economically attractive. Scaling AI will require integrating with legacy systems and redesigning operating models. Friction may be most acute where oversight and liability management require human involvement, particularly where AI missteps could prove costly.
This gradual pace is an important premise of our macroeconomic and asset class assumptions. Steady uptake should limit rapid, economy-wide job displacement and keep broad inflation contained, even as the build-out strains supply chains in the near term.
In our base case, AI boosts U.S. TFP growth above its pre-AI trend by roughly 40bps, to 1.2% annually,[8] and it lifts U.S. capital stock growth by about 30bps, to 2.3% per year. Together, this raises our total U.S. labor productivity forecast by 50bps vs. our pre-AI baseline, to 2.2%. Small gains compound: A sustained 50bps boost over 15 years would make the U.S. economy 7%–8% larger than it otherwise would have been. Given this is our fourth year incorporating AI into our assumptions, this year’s incremental productivity lift vs. last year is 20bps.
Relative to other forecasts, our view appears cautiously optimistic. The 40bps AI-driven TFP uplift exceeds the Congressional Budget Office’s more conservative 10bps estimate while landing in the lower half of the OECD’s 27bps to 85bps scenario range.[9]
Against that backdrop, our analysis first builds a baseline forecast for the U.S., then extends it globally, accounting for regional variation.
TFP: How does task automation become economy-wide productivity?
1. AI exposure
2. Effective penetration
3. Gain per task
4. Labor share of the economy
Capital deepening: How much AI investment will prove productive?
Beyond TFP, our outlook hinges on how much the surge in AI spending ultimately increases productivity.
Since 2023, AI demand and enthusiasm have driven U.S. hyperscalers to cumulatively invest close to USD 1.6 trillion in capex, spanning data centers, power, semiconductors and networking. Globally, the total exceeds USD 2 trillion over the same period.[13]
Our outlook for capital deepening builds on four factors: the path of AI spending, its composition, the rate of depreciation and the extent to which it crowds out other productive capex. Broadly, the first two variables are additive to growth, while the latter two detract.
1. Spending path
2. Spending composition
3. Depreciation
4. Crowding out
A rising tide lifts economies unevenly
Developed markets appear better positioned to deploy AI at scale, given their large service sectors, strong digital infrastructure and supportive institutions. Where workforces are shrinking – from Japan and China to the U.S., Germany and Italy – firms will have a greater incentive to use AI to help offset demographic challenges.
But economic gains will vary between AI enablers, which supply key inputs for the build-out, and adopters, which successfully integrate AI (Exhibit 2). The two can be mutually reinforcing: Better tools and infrastructure can speed up adoption, and durable monetization can incentivize further investment.
The U.S. leads as both an enabler and an adopter, registering the largest AI-driven TFP boost in our forecast universe. Its concentration of frontier model developers, hyperscalers and software platforms is unmatched. Corporate America also has the financial strength and appetite to sustain the AI build-out, supported by a flexible, innovation-oriented business environment.
Meanwhile, Europe’s early AI gains skew toward a few key enablers in areas where it has outsize global influence, notably semiconductor manufacturing equipment and power grid and infrastructure. Broader gains should follow as AI diffuses across Europe’s services-heavy economies (several of which are more AI-exposed than the U.S.). However, its fragmentated single market, legal and regulatory burdens, labor constraints and energy supply vulnerabilities may slow AI’s rollout.
China is building a parallel AI ecosystem, with homegrown models, domestic chip production and a push into robotics. China’s cost competitiveness may prove an advantage, while deployment of AI (which is often state-mandated) across industrial and consumer sectors could drive economy-level productivity gains. Chinese models are also gaining traction globally, recently overtaking U.S. models in token usage on OpenRouter, a widely used developer gateway. Still, weaker monetization by Chinese firms and export controls on advanced U.S. chips should restrain investment and development.
Taiwan and South Korea should continue to benefit from their central role in global tech supply chains, notably in advanced semiconductor manufacturing. Both economies rank among the largest upward revisions to our GDP growth assumptions. That competitive position is a strength but also a risk, as economic nationalism and geopolitical uncertainty drive the U.S. and China toward onshore alternatives. Finally, Japan arguably has the strongest incentive to adopt AI, given its aging workforce, but long-tenure norms may hinder diffusion.
Multiple paths ahead
Our base case is just one plausible path among many alternate scenarios (Exhibits 3A and 3B).
AI could disappoint if regulation or social backlash restrains adoption, or if capex resets more sharply due to obsolescence, margin pressure, tighter financing or power constraints. Even with broad diffusion, AI may still underdeliver if oversight adds more work, time savings shift to leisure rather than new tasks, or skill gaps and worker preferences become binding constraints. Such a downside scenario could see AI reach only a quarter of tasks by 2040 (vs. 40% in our base case) and annual TFP growth settle below 1%.
We expect stronger TFP growth and sustained capital investment, but a range of outcomes could unfold
From productivity to portfolios
Despite the profound impact AI has already had on markets, we don’t think its potential is fully appreciated.
Investors will seek to identify where value accrues, whether through profit growth, risk premia or pricing power. We believe portfolios can best capture that potential by balancing exposure across the AI value chain and funding cycle, spanning public and private markets. That calls for strategic discipline and tactical flexibility.
Returns have so far favored the AI enablers. But the set of beneficiaries already extends beyond hyperscalers and semiconductors into infrastructure and power. As adoption spreads, more sectors should participate. This expectation underpins our view that equities will deliver stronger, broader earnings growth and sustain structurally higher margins and valuations than they would have in a world without AI.
Value should shift toward adopters deploying AI, in areas such as predictive analytics, speed to market, product fit and supply chain management. Financial services, health care, retail and logistics firms are among such early adopters and tend to rank higher in measures of AI exposure and labor intensity (Exhibit 4).
The U.S. remains at the core of global allocations, offering exposure to a vibrant culture of innovation, tech-heavy indices and deep capital markets. It ranks among the highest in profit margins in our forecast universe. In Europe, value stands to remain concentrated in “pick-and-shovel” enablers until adoption broadens. And while Asian companies should remain essential to tech supply chains, the strength of the current capex wave may have pulled forward some revenue and margin gains, making stock selection crucial after recent investor optimism.
We anticipate that the capex build-out will contribute to our outlook for higher real rates, elevated term premia and steeper yield curves, even if AI produces disinflationary effects over time. Credit issuance is rising as hyperscalers become a more pronounced presence in debt markets, lifting index quality despite biasing spreads wider. Investors may find relative value in issuers that can fund investment without stretching balance sheets, though complex financing structures and off-balance sheet obligations warrant scrutiny. Because the AI ecosystem is so interconnected, cross-asset correlations may shift in ways that make traditional diversification less reliable.[18]
Alternative assets can reach parts of the AI value chain that public markets cannot, potentially improving portfolio diversification. Commodities supply key inputs. Infrastructure and real estate add critical capacity across power, cooling, transmission and storage, and offer inflation resilience via contracted cash flows. But risk profiles vary widely, from regulated grid power to data centers and on-site generation, and warrant specialized underwriting.
Private equity managers can enhance value creation and improve operating efficiency by deploying AI across portfolio companies. Meanwhile, venture capital backs many of the AI-native companies now growing to unprecedented scale in private markets, albeit with highly skewed outcomes. Private credit in turn finances parts of the AI build-out, though deal terms will need to evolve in tandem, given direct lending’s meaningful exposure to software and technology. And as disruption accelerates, hedge funds may capitalize on dislocations. Above all, manager selection will be critical, as outcomes may vary considerably by exposure, vintage and strategy.
As we model the world in 2040, we believe the AI ecosystem will evolve in ways that prove transformative. This should drive efficiency gains, support margin resilience and unlock new growth opportunities that extend well beyond the tech sector. But the path of adoption and diffusion won’t be smooth, bringing higher volatility and wider dispersion that necessitate a disciplined, diversified approach. Investors should build AI exposure intentionally and prepare to shift course as a new era of innovation and value creation unfolds.

Early signals of AI-driven productivity gains have been ambiguous, consistent with past technological shifts where productivity often lags during early adoption (the “productivity J-curve”). As such, the recent firming in U.S. productivity may better reflect supply-side shocks than AI. See Stephanie Aliaga, “Is AI already driving productivity growth?” J.P. Morgan Asset Management, March 11, 2026.

More discernible signs of AI’s productivity impact are emerging in the information sector, where output per hour has grown roughly 9% annualized since late 2022. That is about three times the pace of nonfinancial corporates, reflecting the information sector’s early role in building and deploying AI.

We anchor our U.S. AI capex assumption to the current and projected spend by the five largest hyperscalers (Alphabet, Meta, Amazon, Microsoft and Oracle). We restrict our analysis to U.S.-located investment, which we then scale up to reflect capex by neoclouds, enterprises and governments.

Projecting AI spending is inherently difficult, and the outlook has shifted considerably in just the past year. This trajectory reflects the best estimate from the LTCMA research and investment teams, and we will revise as conditions evolve.

We allocate AI capex across three categories and assume the mix shifts over time. We estimate that equipment (GPUs, servers, memory and networking) falls from just over 40% of AI capex in 2026 to 30% by 2040. At the same time, structures (data centers and power infrastructure) rise from 30% to 40% and intellectual property products (software and R&D) increase from about 25% to 30%.

KEY RISKS
Diversification and asset allocation does not ensure a profit or protect against loss.
Private investment funds (including, without limitation, hedge funds, funds of hedge funds, private equity funds, real estate funds, etc.) are subject to special risks, including risk of loss of the entire investment and is suitable only for investors with sufficient knowledge and sophistication to evaluate the merits and risks of such investments. As a reminder, private investment funds often engage in leveraging and other speculative investment practices that may increase the risk of investment loss. These investments can be highly illiquid, and may not be required to provide periodic pricing or valuation information to investors, and may involve complex tax structures and delays in distributing important tax information. Distributions are not guaranteed and may be modified at the Fund Board’s discretion. These investments are not subject to the same regulatory requirements as mutual funds; and often charge high fees (performance fees in addition to management fees). Further, any number of conflicts of interest may exist in the context of the management and/or operation of any such fund.
