In an era defined by rapid technological advancement and geopolitical shifts, thematic investing has emerged as a powerful strategy to harness long-term growth drivers.

Megatrends such as economic security and energy transition are set to redefine investment paradigms in 2026, offering compelling avenues for portfolio diversification and resilience.

This approach allows investors to align their capital with structural changes shaping economies, from AI expansion to sustainable solutions.

By focusing on themes rather than short-term fluctuations, investors can build positions in companies poised to thrive amid disruption.

Thematic funds provide exposure to these trends through various asset classes, including public equities, private markets, and fixed income.

Understanding the core themes and practical opportunities is essential for navigating this dynamic landscape and achieving sustainable returns.

Economic Security: Fortifying Global Foundations

Economic security is a critical theme driven by geopolitical tensions and supply chain vulnerabilities.

It emphasizes resilient supply chains and critical resources, such as semiconductors and LNG exports, to enhance national defense and energy independence.

Key opportunities arise in companies that bolster infrastructure and reduce dependencies, with active managers able to pick winners.

Data centers now consume 3% of US power, projected to rise to 8% by 2030, highlighting surging energy demands.

Over 750,000 new power workers will be needed by 2030 in the US and Europe, addressing an aging workforce.

• Focus on resilient supply chains and critical mineral resources.
• Emphasis on national defense and LNG export capabilities.
• Opportunities in semiconductors and resource security initiatives.
• Driven by tariffs, geopolitics, and reindustrialization efforts.

Sustainable Investing and Energy Transition: Maturing for Performance

Sustainable investing is evolving beyond labels to prioritize cost-saving solutions and performance metrics.

Renewables, grids, and energy storage represent mature sub-themes with rising investment, while hydrogen and carbon capture face declining interest.

Higher inflation favors technologies that offer scale and efficiency, making "pick-and-shovel" companies in the value chain attractive.

Physical risks, such as $1 trillion in US disaster recovery costs in one year, underscore the need for adaptation investments.

The circular economy, including waste recycling and resource depletion solutions, addresses infrastructure gaps from landfill closures.

• Prioritize renewables, grids, and energy storage for robust returns.
• Avoid hydrogen and carbon capture due to investment declines.
• Focus on cost-saving solutions amid inflationary pressures.
• Address physical risks through climate adaptation measures.
• Explore circular economy opportunities in waste management.

AI and Power Demand: Broadening the Investment Trade

The AI revolution is expanding from semiconductor builders to beneficiaries across industries like healthcare and logistics.

Fear of being outbid or outbuilt drives second-wave capex, fueling growth in software, industrials, and financial services.

Energy security becomes paramount, with fossil fuels, nuclear, and grids coexisting with renewables to meet surging power demand.

Uranium, utilities, and oil/gas sectors offer investment opportunities as data centers accelerate energy needs.

Speed to power favors near-term renewable solutions over gas and nuclear constraints.

• From AI builders to beneficiaries in diverse sectors.
• Energy security integrating multiple power sources.
• Surging power demand from AI and data centers.
• Investment in uranium and utility infrastructure.

Policy and Macro Shifts: Navigating Monetary and Fiscal Changes

Monetary policy shifts towards accommodation, with rate cuts and easing conditions, favor growth equities and emerging markets.

Fiscal policies fill growth gaps, supporting quality tech in the US, EU, and Japan through targeted investments.

Investors should consider rotating into value, cyclicals, and real assets like financials and materials for diversification.

Volatile two-way markets from policy and geopolitics offer tactical plays for agile investors.

• Monetary easing benefits growth equities and long-duration assets.
• Fiscal support enhances tech and cyclical sectors.
• Rotation into value, cyclicals, and real assets.
• Tactical opportunities in policy-driven volatility.

Asset Class Opportunities: Diversifying Across Markets

Thematic investing spans multiple asset classes, each offering unique exposure to growth trends.

In public markets, ETFs and active funds provide targeted access through diversified portfolios.

The table below highlights key ETFs and funds for various thematic opportunities in 2026.

Private markets, including private equity and credit, offer middle-market sustainability investments with non-dilutive financing.

Private equity focuses on waste, materials, and sustainable food, targeting profitable firms with efficient solutions.

Private credit addresses an imbalance, with $61 billion raised since 2014 versus $781 billion for private equity.

Infrastructure projects in AI, energy, and circular economy benefit from government withdrawals and value-add opportunities.

Fixed income includes securitized assets, municipal bonds, and green bonds for diversification and steady returns.

Green bonds are growing as a diversified market with sector differences from conventional bonds.

Key Questions and Risks for Investors

While thematic investing offers promise, it requires vigilance on risks and broader market context.

Investors should monitor emerging themes like circular economy and adaptation solutions for physical risks.

Risks include slower AI productivity and policy shocks, which could impact returns and stability in volatile markets.

Overbuild in capex, inflation persistence, and growth rollovers pose challenges that demand careful analysis.

Currency and political noise add complexity, emphasizing the need for high-quality stock selection over macro trends.

• Monitor circular economy, food, agriculture, and water themes.
• Assess physical risk and adaptation costs from climate events.
• Beware of overbuild in capital expenditure and inflation risks.
• Navigate policy shifts and potential growth slowdowns.
• Consider currency fluctuations and geopolitical uncertainties.
