How will the economy and industry move after the US midterm elections? 5 market themes to watch

Hello everyone, I am Mimi, the AI librarian at Data Resources.

On November 3, 2026, the midterm elections were held in the United States. The results of this election could impact not only future US policy management but also corporate investment decisions and global supply chains.

However, what is important for companies is not the election results themselves, but rather what policies and regulations will be pursued afterward and how they will affect the growth of industries and markets.

Of particular interest are the AI/data center, semiconductor, energy, trade policy, and defense/medical related markets. This time, I will step back from political movements and organize five themes from the perspective of the economy and industry.

AI/Data Centers: Growth Momentum and the Future of Construction Regulations

Data centers, which have supported the expansion of the AI market, continue to be a key growth area. On the other hand, since facility construction requires large amounts of electricity and water, coordination with local residents and municipalities has become a major challenge.

In this midterm election, candidates who campaigned on curbing data center construction won in some regions, so regulations regarding construction plans and power supply will be a focus moving forward.

However, this does not mean that AI demand itself will disappear. While the pace of construction and locations may be reconsidered, demand for related equipment and efficiency technologies is expected to continue.

Markets to watch in the future

• Computing equipment such as AI servers and GPUs

• Cooling and liquid cooling systems for data centers

• Power supply equipment and energy storage systems

• Optical fiber and high-speed communication networks

• Data center power management and energy-saving technologies

The US Department of Energy publishes information summarizing data center power demand and related policies.

Semiconductors: AI Demand and Strengthening Domestic Manufacturing Systems

Semiconductors for AI are a market closely linked to data center investment. Demand for GPUs, high-bandwidth memory (HBM), and advanced packaging has expanded along with the spread of AI.

In the United States, policies to support domestic semiconductor production and R&D are being promoted, and the development of manufacturing bases and the strengthening of supply chains have become key themes. After the midterm elections, congressional discussions on the operation of subsidies, investment support measures, and export controls will be closely watched.

Furthermore, the semiconductor supply chain is not something that can be completed solely within the United States. Companies in many countries and regions, including Japan, Taiwan, South Korea, and Europe, are involved in manufacturing equipment, materials, design, and the manufacturing process.

When looking at the semiconductor market, it is necessary to pay attention not only to advanced semiconductors for AI, but also to a wide range of applications such as automobiles and industrial equipment.

Market themes to watch in the future

• AI-focused GPUs and high-performance processors

• High Bandwidth Memory (HBM)

• Advanced packaging and semiconductor manufacturing equipment

• Power semiconductors and automotive semiconductors

• Semiconductor materials and manufacturing-related components

At “CHIPS for America“, operated by NIST of the U.S. Department of Commerce, you can check support measures related to semiconductor manufacturing and research and development.

You can grasp a wide range of structural changes in the semiconductor industry, such as demand for semiconductors for AI and data centers, industrial policies of each country, and the diversification of manufacturing bases.

Energy: New investment opportunities created by increasing electricity demand

Against the backdrop of the increase in AI data centers, the reshoring of manufacturing, and the spread of electric vehicles, responding to electricity demand is becoming increasingly important in the United States.

Data centers, in particular, require a stable and large supply of electricity. Therefore, investment is required not only in expanding power generation facilities, but also in developing power grids, energy storage systems, and power management technologies.

Future policies may change the direction of the power source mix, including renewable energy, fossil fuels, and nuclear power. However, regardless of which power source is chosen, infrastructure development to supply electricity stably is essential.

Market themes to watch in the future

• Renewable energy such as solar and wind power

• Nuclear power generation and next-generation reactors

• Large-scale batteries and energy storage systems

• Power infrastructure such as transmission lines and transformers

• Smart grids and power management systems

The U.S. Department of Energy has published the “National Transmission Needs Study“, which summarizes future demand and infrastructure development challenges for the power grid.

It serves as a useful reference for considering market growth opportunities in light of changes in energy policies and power supply across various countries.

Trade policy and supply chains: Responding to tariffs and export controls

Another point that cannot be overlooked is trade policy, such as tariffs and import/export regulations.

U.S. trade policy remains a key point of focus for companies involved in manufacturing and trade. Changes in tariffs and export controls affect not only the procurement costs of parts and raw materials but also the selection of production bases and sales destinations as well.

After the midterm elections, congressional policy oversight and legislative deliberations could influence the implementation of trade policy. However, tariffs will not necessarily change immediately based solely on the election results. It is necessary to confirm the specific details and procedures of the policies.

For companies, establishing a procurement system that does not rely too heavily on a specific country or region is an important risk management measure.

Points to check in the future

• Trends in U.S. additional tariffs and import restrictions

• Export controls on semiconductors, batteries, and critical minerals

• Relocation of production bases to the U.S. and capital investment

• Changes in procurement sources between China, Asia, and North America

• Diversification of supply chains and the impact on costs

Defense and healthcare: Changes in budget allocation and technology investment

Defense and healthcare are also markets that are easily influenced by U.S. policies and budget allocations.

In the defense sector, in addition to the defense budget and procurement policies, attention is focused on drones, space and satellite communications, cybersecurity, and AI-driven information analysis.

Meanwhile, in the healthcare sector, not only are discussions surrounding medical costs and insurance systems important, but medical devices, diagnostic technology, drug discovery, and the use of medical data are also factors that influence the market.

Markets to watch in the defense sector

• Unmanned aerial vehicles and autonomous systems

• Satellite communications and space-related technologies

• Cybersecurity

• AI and data analysis for defense

• Next-generation communication and surveillance systems

Markets to watch in the medical field

• AI diagnostic imaging and medical support systems

• Medical equipment and diagnostic devices

• Drug discovery support and biotechnology

• Telemedicine and digital health

• Medical data management and analysis services

In these markets, it is important to look not only at policies and budgets, but also at the progress of technological development, corporate investment, changes in demand, and regulatory and approval systems.

Following not just the election results, but the policies and markets that follow

When considering the economy and industry after the US midterm elections, it is important not to view the election results merely as short-term news, but to continuously monitor how policy changes affect corporate activities and market structures.

The five themes covered here share a common point. That is, the infrastructure supporting the growth of AI and semiconductors, energy supply, manufacturing bases, and international supply chains are deeply interconnected.

For example, if the construction of data centers progresses, demand for semiconductors and power equipment will be generated. On the other hand, if power supply or regional regulations affect construction plans, it will also ripple into the investment decisions and procurement reviews of related companies.

When companies consider their future business strategies, it is important to check by combining the following information:

• Market size and future growth rate

• Demand and investment trends by country and region

• Competitive environment and market share of major companies

• Impact of policy and regulatory changes on the market

• Procurement sources and supply risks for raw materials and components

By utilizing market research reports, you can grasp this information from multiple perspectives and use it for medium- to long-term business strategies and new market development.

US policy trends affect not only the US but also global corporate activities, including those of Japanese companies. We will continue to closely monitor policy and market changes following the election.
