The Looming Semiconductor Crunch: AI’s Growing Appetite for Chips

As artificial intelligence accelerates across industries, the demand for semiconductors is surging. From graphics processing units (GPUs) powering data centers to advanced chips enabling AI in personal devices, the semiconductor supply chain is facing unprecedented pressure. This next wave of demand, fueled by AI adoption and bolstered by innovations in devices like PCs and smartphones, could result in a new semiconductor shortage—one that businesses can’t afford to ignore.

The AI Impact on Semiconductor Demand

AI-Driven Data Center Growth

The rise of generative AI, particularly large language models (LLMs), has sparked a surge in data center investments. GPUs are critical for training and operating these models, driving exponential demand for advanced chips and components. Key insights include:

• Doubling GPU Demand: By 2026, GPU demand for AI training could double, requiring upstream component suppliers to boost output by 30% or more.

• Pull-Through Demand: Growth in AI workloads necessitates increased production in advanced packaging (e.g., chip-on-wafer-on-substrate or CoWoS) and high-bandwidth memory.

• Supply Chain Complexity: Scaling AI infrastructure involves not just GPUs but also electricity, cooling systems, and networking equipment, each with significant lead times and investment needs.

AI-Enabled Devices

AI is transforming personal devices like PCs and smartphones, embedding advanced neural processing capabilities directly into hardware. As AI applications become integral to user experiences, consumers are likely to upgrade their devices sooner than anticipated.

• Increased Silicon Area: AI-enhanced processors in notebooks and smartphones have grown in size by 5% and 16%, respectively.

• Pandemic-Like Uptick: Similar to the pandemic’s surge in PC demand, AI applications could trigger a 31% increase in PC sales and 15% growth in smartphones between 2023 and 2026.

• Bleeding-Edge Fabs: Meeting this demand will require four to five new fabs, costing $40 billion to $75 billion.

The Risks Ahead: Supply Chain Vulnerabilities

The semiconductor industry operates within a fragile ecosystem. Any disruption, whether geopolitical, environmental, or logistical, can ripple through the supply chain. Here are the key risks:

1. Geopolitical Tensions

• Trade Restrictions: Ongoing decoupling of supply chains from China adds layers of complexity and uncertainty.

• Tariffs and Regulations: These factors could delay access to critical materials and impact global chip supply.

2. Supply Chain Chokepoints

• Advanced Packaging: CoWoS capabilities remain a bottleneck, with limited suppliers able to scale production.

• High-Bandwidth Memory: Surging demand for AI workloads will test the limits of current memory production.

3. Environmental and Labor Challenges

• Construction Delays: Building fabs and advanced packaging facilities takes years, with labor shortages adding to the timeline.

• Energy Strain: Expanding semiconductor fabs and data centers will compete with rising electricity demands from other sectors like EVs and manufacturing.

How Companies Can Prepare

Proactive measures are essential to avoid being caught off guard by the next semiconductor shortage. Here’s how businesses can reinforce their supply chains:

1. Secure Long-Term Agreements

Lock in long-term purchase contracts with suppliers to ensure access to critical components. Sharing demand forecasts with suppliers will help them align capacity planning with market needs.

2. Diversify Supply Chains

Reduce dependency on single regions or suppliers by diversifying procurement strategies. Identify alternative sources for advanced packaging, memory, and substrate components.

3. Adopt Resilient Inventory Strategies

Move from “just-in-time” to “just-in-case” inventory models, maintaining higher stock levels to weather supply disruptions. This may involve rethinking cost structures to prioritize resilience over short-term savings.

4. Focus on Standardization

Design products to use industry-standard semiconductors where possible, reducing reliance on custom chips that can be harder to source during shortages.

5. Monitor Emerging Risks

Keep a close eye on geopolitical developments, environmental risks, and supply chain dynamics. Early identification of potential disruptions can enable faster responses.

Case in Point: Lessons from the Pandemic

The pandemic-induced semiconductor shortage left industries reeling, with automakers unable to complete vehicles due to missing chips. This experience underscores the importance of planning ahead:

• Visibility Across Tiers: Gain a deeper understanding of not just direct suppliers but also their upstream networks.

• Invest in Resilience: Allocate resources to buffer against external shocks, including building relationships with multiple suppliers and investing in supply chain technology.

The Path Forward: Navigating the AI Boom

AI is driving a transformative shift in the semiconductor market, with demand surging across data centers, PCs, smartphones, and beyond. While the challenges are significant, so are the opportunities for companies that take a proactive approach.

Executives must recognize the signs of an impending supply crunch and act swiftly to strengthen their supply chains. With the right strategies in place—long-term agreements, diversification, and resilient inventory models—businesses can position themselves to thrive in an increasingly AI-driven world.

The next semiconductor shortage is not a question of if but when. The time to prepare is now.
