The World's Fastest-Growing Industries in 2026

Discover the industries experiencing rapid growth in 2026, from artificial intelligence and data centers to renewable energy, cybersecurity, robotics, electric vehicles and digital services.

The global economy is changing quickly.

Artificial intelligence is creating enormous demand for computing infrastructure. Renewable energy is expanding at record levels. Electric vehicles are moving into mainstream markets. Robotics is spreading through factories and warehouses. Cybersecurity is becoming increasingly important as businesses become more digital.

At the same time, digital commerce, cloud computing, advanced manufacturing and other technology-driven industries are continuing to reshape how companies operate.

The overall global economy is still growing at a much slower rate than some individual industries. The IMF's July 2026 outlook projects global economic growth of 3.0% in 2026, with technology-related investment helping support activity even as geopolitical and energy risks weigh on the outlook.

That contrast is important.

An industry can grow rapidly even when the overall economy is expanding moderately.

Here are some of the sectors showing particularly strong momentum in 2026.

1. Artificial Intelligence

Artificial intelligence is one of the most rapidly expanding areas of the global economy.

The AI industry is no longer limited to research laboratories and experimental consumer applications. Companies are integrating AI into software, customer service, marketing, finance, healthcare, manufacturing, logistics and professional services.

Gartner forecasts worldwide AI spending of approximately $2.7 trillion in 2026, representing a 49.5% increase from 2025. AI infrastructure remains the largest component of this spending, driven by demand for computing capacity, AI-optimized servers, networking and other infrastructure.

The expansion is happening across several layers:

• AI models

• AI software

• AI services

• AI agents

• AI infrastructure

• AI chips

• AI-enabled applications

• AI cybersecurity

• Data and machine-learning platforms

This makes AI less like a single industry and more like a technology layer spreading throughout the economy.

2. Data Centers and AI Infrastructure

The growth of AI is creating another rapidly expanding industry: data-center infrastructure.

Every AI model requires computing power.

That means demand is increasing for:

• Data centers

• AI servers

• Advanced processors

• Networking equipment

• Cooling systems

• Storage

• Cloud infrastructure

• Backup power

• Electricity generation

Gartner estimates that worldwide IT spending will reach $6.37 trillion in 2026, up 14.2% from 2025, with data-center systems and infrastructure-as-a-service among the major growth drivers.

An earlier 2026 Gartner forecast projected data-center spending growth of 31.7%, illustrating how rapidly infrastructure investment has been accelerating.

The data-center boom is therefore becoming an economic story in its own right.

3. Cybersecurity

As more companies move their operations online, protecting digital systems becomes increasingly important.

Cybersecurity spending is expanding because businesses must defend against ransomware, identity theft, data breaches, supply-chain attacks and increasingly sophisticated digital threats.

Gartner forecasts worldwide information-security spending of about $244 billion in 2026, representing 11.6% constant-currency growth.

AI is also creating an entirely new cybersecurity market.

Organizations now need to protect AI models, AI applications and autonomous AI agents as well as traditional networks and devices.

Gartner forecasts spending on technologies specifically designed to secure AI at about $2.84 billion in 2026, with the market projected to grow rapidly into 2027.

Cybersecurity is therefore expanding both because of digital transformation and because AI is creating new categories of risk.

4. Renewable Energy

Renewable energy continues to be one of the world's fastest-expanding energy industries.

Solar and wind power are driving much of the growth.

The IEA reports that global renewable capacity additions reached a record 800 gigawatts in 2025, up 16% from the previous year. Solar PV accounted for more than three-quarters of new renewable capacity, while wind accounted for about 20%.

Solar PV additions alone exceeded 600 GW in 2025.

The scale is significant because renewable energy is no longer a small alternative segment of the electricity market.

It is becoming one of the main sources of new global power capacity.

5. Battery Storage

Renewable energy growth is also creating a rapidly expanding market for batteries.

Solar and wind generation can fluctuate, while electricity demand continues throughout the day and night.

Battery storage helps electricity systems manage that variability.

According to the IEA, battery storage was the fastest-growing power technology in 2025, with capacity additions increasing by around 40% to nearly 110 GW.

Demand is being driven by several markets:

• Utility-scale batteries

• Solar-plus-storage systems

• Electric vehicles

• Home energy storage

• Commercial backup systems

• Grid stabilization

As electricity systems become more dependent on variable renewable generation, storage is becoming increasingly important infrastructure.

6. Electric Vehicles

The electric-vehicle industry continues to expand despite differences between individual markets.

The IEA reports that global electric-car sales exceeded 20 million vehicles in 2025, increasing about 20% from 2024 and representing roughly one-quarter of new car sales worldwide.

The 2026 outlook also points to continued expansion.

The IEA expects global electric-car sales to reach approximately 23 million in 2026, representing around 28% of total car sales. It forecasts particularly strong growth in Asia-Pacific markets outside China and Latin America.

The EV industry extends far beyond automobiles.

It is creating demand for:

• Batteries

• Charging infrastructure

• Power electronics

• Electric motors

• Battery materials

• Software

• Fleet-management systems

• Electric buses

• Electric trucks

• Electric two- and three-wheelers

The transition is therefore creating an entire industrial ecosystem.

7. Robotics and Automation

Factories are becoming increasingly automated.

Robots are being used for manufacturing, assembly, packaging, logistics, warehousing, inspection and other industrial tasks.

The latest World Robotics data from the International Federation of Robotics show that the global operational stock of industrial robots reached approximately 5.08 million units in 2025, up 9% from the previous year.

Annual installations exceeded 603,000 units, an 11% increase.

The growth is particularly visible in Asia.

China alone installed approximately 354,000 industrial robots in 2025, with annual installations increasing 20% year over year.

The next phase of industrial automation is increasingly connected to AI.

Machines are becoming better at interpreting visual information, responding to changing environments and working alongside human operators.

8. Cloud Computing

Cloud computing remains a foundational part of the digital economy.

Businesses increasingly depend on cloud infrastructure for:

• Data storage

• Software

• AI

• Business applications

• Cybersecurity

• Analytics

• Collaboration

• E-commerce

The rapid expansion of AI is adding another layer of demand.

AI workloads require enormous computing capacity, and many businesses access that capacity through cloud platforms.

This means AI and cloud computing are increasingly interconnected industries rather than separate technology trends.

9. Semiconductors

The semiconductor industry sits underneath many of the world's fastest-growing technologies.

AI systems require advanced processors.

Electric vehicles use sophisticated electronics.

Modern smartphones depend on semiconductor components.

Robots, data centers, medical equipment, communications infrastructure and industrial systems all rely on chips.

The AI infrastructure boom is therefore creating strong demand for advanced processors and related semiconductor manufacturing equipment.

The semiconductor industry is also becoming increasingly important to national industrial strategies as companies and governments seek more resilient supply chains.

10. Digital Commerce

E-commerce has evolved from an alternative shopping channel into a core part of global retail.

UN Trade and Development reported in July 2026 that global e-commerce exceeds $28 trillion, while digitally deliverable services account for 56% of global services exports.

The growth of digital commerce includes much more than online shopping.

It encompasses:

• Digital marketplaces

• Online services

• Mobile commerce

• Digital advertising

• Social commerce

• Online subscriptions

• Cross-border commerce

• Digital business services

The expansion of smartphones and digital payments is helping bring more consumers into the digital economy.

11. Digital Financial Services

Financial services are also becoming increasingly digital.

Consumers can increasingly open accounts, send money, make payments, borrow, invest and manage businesses through smartphones and online platforms.

The expansion of digital finance is particularly significant in emerging markets, where mobile technology can allow consumers and businesses to access financial services without relying entirely on traditional banking infrastructure.

Digital payments are also becoming increasingly important to international commerce.

For businesses, this creates opportunities in:

• Payment processing

• Digital wallets

• Merchant platforms

• Cross-border payments

• Fraud prevention

• Digital banking

• Financial software

The industry is increasingly connected to the broader growth of e-commerce.

12. Advanced Manufacturing

Manufacturing is entering a new phase driven by automation, artificial intelligence, robotics, advanced materials and increasingly sophisticated software.

Factories are becoming more connected.

Machines can generate data about production processes.

AI can help identify patterns and potential quality problems.

Robots can automate repetitive tasks.

Digital systems can help companies monitor supply chains and production in real time.

This combination is often described as smart manufacturing or Industry 4.0.

It is creating new opportunities for companies that can combine physical production with software and data.

13. Biotechnology and Life Sciences

Biotechnology remains another major area of investment and innovation.

Advances in genetics, molecular biology, drug discovery, diagnostics and computational biology are creating new opportunities across healthcare and life sciences.

AI is also beginning to influence drug discovery and biological research by helping researchers analyze large datasets and identify potential relationships.

Unlike some digital industries, biotechnology generally requires longer development cycles and significant regulatory approval.

Its growth therefore tends to be measured differently from software or consumer technology.

Nevertheless, the sector remains an important part of the global innovation economy.

14. Digital Health

Healthcare is also becoming increasingly digital.

Telemedicine, remote monitoring, health software, digital diagnostics and AI-assisted medical tools are changing how healthcare services can be delivered.

Digital health can help connect patients with healthcare providers without requiring every interaction to take place in a hospital or clinic.

The opportunity is particularly significant in countries where healthcare resources are unevenly distributed.

However, healthcare technology faces higher regulatory and safety requirements than many consumer applications.

Growth therefore depends not only on technology but also on evidence, regulation and trust.

15. Space Technology

The space economy is expanding beyond traditional government-led programs.

Private companies are developing launch systems, satellites, communications networks, Earth-observation technologies and other commercial services.

Satellite connectivity is also becoming increasingly important for remote communities, transportation, maritime industries and businesses operating in areas without reliable terrestrial infrastructure.

The broader space industry includes:

• Satellite communications

• Earth observation

• Launch services

• Space manufacturing

• Navigation

• Remote sensing

• Commercial research

As launch costs and satellite technology evolve, more businesses are finding ways to participate in the space economy.

16. The Creator and Digital Media Economy

The global creator economy continues to expand as individuals build businesses around video, music, newsletters, podcasts, social media, education and digital products.

AI is accelerating this trend by lowering the cost of producing content.

A small team can now produce writing, images, video, audio and marketing materials at a scale that previously required much larger organizations.

This creates opportunities for independent publishers, influencers, educators, entertainers and niche media companies.

It also means competition for audience attention is increasing.

17. Why These Industries Are Growing

Although these industries are very different, several forces connect them.

Artificial Intelligence

AI is becoming a general-purpose technology affecting software, manufacturing, healthcare, finance, media and energy.

Electrification

Cars, buildings, industrial systems and other technologies are increasingly using electricity rather than direct fossil-fuel combustion.

Digitalization

Businesses continue moving operations, transactions and customer interactions online.

Automation

Companies are using machines and software to increase productivity and manage labor constraints.

Climate and Energy Investment

Renewable power, storage, electric vehicles and grid infrastructure are receiving significant investment.

Global Connectivity

The internet allows businesses to reach customers and partners across borders.

These forces reinforce one another.

AI increases demand for data centers.

Data centers increase electricity demand.

Electricity demand increases interest in new generation and storage.

Manufacturing more advanced equipment requires robotics and semiconductors.

Digital businesses require cybersecurity.

The result is a connected ecosystem rather than a collection of isolated industries.

The New Geography of Growth

Growth is also becoming more geographically distributed.

Asia remains central to manufacturing, electronics, electric vehicles, renewable energy and robotics.

North America remains a major center for AI, software, cloud computing and technology investment.

Europe is investing heavily in renewable energy, electrification, industrial technology and digital transformation.

Emerging markets are becoming increasingly important in digital commerce, mobile services, electric mobility and renewable energy.

The IEA reported that renewable capacity additions in sub-Saharan Africa and the Middle East and North Africa each doubled in 2025 to around 12 GW.

Meanwhile, the IEA found that electric-car sales in emerging and developing economies outside China increased by around 80% in 2025, reaching nearly 1.2 million vehicles.

This means the next phase of global industrial growth is unlikely to be concentrated in only a few traditional economic centers.

What Businesses Should Watch

Companies operating in almost every sector are being affected by these trends.

A retailer may need digital commerce and AI.

A manufacturer may need robotics.

A financial company may need digital payments and cybersecurity.

A logistics company may need automation and electric vehicles.

A media company may need AI-assisted production and digital distribution.

An energy company may need renewable generation, storage and grid technology.

The boundary between industries is becoming less clear.

Technology is increasingly becoming part of the operating model of traditional businesses.

The Risks Behind Rapid Growth

Fast-growing industries also face major challenges.

AI requires enormous amounts of computing power and electricity.

Renewable energy requires investment in grids and storage.

Electric vehicles depend on battery supply chains.

Cybersecurity companies must keep pace with rapidly evolving threats.

Robotics can require significant upfront investment.

Digital businesses face regulatory and privacy concerns.

The IMF's 2026 outlook also highlights uncertainty from geopolitical conflict, financial-market repricing and the possibility that expected technology-driven productivity gains may not fully materialize.

Rapid growth does not guarantee that every company or investment within an industry will succeed.

The Industries to Watch Through the Rest of the Decade

Several of the strongest 2026 trends are likely to remain important beyond this year.

AI infrastructure could continue expanding as businesses deploy increasingly sophisticated models and AI agents.

Renewable energy and battery storage could continue reshaping electricity systems.

Electric vehicles could capture a larger share of new vehicle sales.

Robotics could become increasingly integrated with AI.

Cybersecurity could become more important as businesses become more dependent on digital systems.

And digital commerce could continue expanding across emerging markets.

The most interesting developments may happen where these industries overlap.

The Bigger Picture

The world's fastest-growing industries in 2026 are being shaped by a small number of powerful forces: AI, electrification, automation, digitalization, connectivity and the transition toward new energy systems.

Artificial intelligence spending is forecast to approach $2.7 trillion this year, while renewable energy added a record 800 GW of capacity in 2025. Electric-car sales exceeded 20 million globally, and the world's industrial robot stock surpassed five million units.

These numbers tell a broader story.

The global economy is not changing through one technology or one industry.

It is changing through multiple industries reinforcing one another.

AI needs chips and data centers.

Data centers need electricity.

Electricity systems need generation, grids and storage.

Manufacturing needs automation.

Digital businesses need cybersecurity.

Consumers need digital payments and connected services.

That interconnected growth is likely to define much of the global economy through the rest of the 2020s.

For businesses, investors, workers and entrepreneurs, understanding these connections may be just as important as understanding the individual industries themselves.
