or decades, semiconductors quietly powered every major tech breakthrough—from personal computing to smartphones to AI. But today, they’ve become more than just the muscle behind machines. They’re now central to global power struggles, economic security, and national sovereignty. In short, chips are no longer just about hardware—they’re about hegemony.
As the U.S. and China enter a new phase of technological competition, venture capitalists are zeroing in on semiconductors as a high-stakes frontier. Whether it’s AI accelerators, photonic chips, or fabless design platforms, the semiconductor space is undergoing a renaissance—and VCs are once again part of the story.
A Cold War Over Chips
Semiconductors are foundational to everything from cloud computing to AI, defense systems to autonomous vehicles. They’re the infrastructure of the digital economy—and control over their production is becoming a geopolitical flashpoint.
The U.S. wants to reshore production and retain control over chip design. China, under pressure from sanctions, is rapidly building its own domestic supply chain. Both countries are investing billions. For VCs, this tug-of-war is creating a flood of demand—and a massive funding gap that startups are rushing to fill.
Why Semiconductors Are Having a Moment
The global semiconductor market is projected to triple from $681B in 2024 to over $2T by 2032. While legacy players like Intel, Nvidia, and TSMC dominate headlines, the real innovation is happening in startups building next-generation infrastructure, tools, and materials.
Drivers of VC interest include:
- AI infrastructure demand: Generative AI models need custom chips for training and inference.
- New architectures: Chiplets, photonics, and quantum-adjacent technologies are unlocking new design paradigms.
- Resilience + independence: National governments are hungry for domestic solutions, and they’re willing to fund them.
Venture capital’s role in this industry is nothing new—early backers of Intel and Nvidia helped define Silicon Valley. But today’s bets are even bigger, with geopolitical relevance and multi-billion dollar addressable markets.
Photonics, Not Just Electrons
One of the most exciting sub-sectors for VCs is photonic semiconductors—chips that use light instead of electricity. Photons move faster, waste less energy, and can transmit data over longer distances. That’s a game-changer for AI, cloud computing, and large-scale data centers.
Recent highlights:
- Lightmatter raised $400M to build light-based AI data centers.
- Ayar Labs secured $130M for optical I/O tech, removing bandwidth bottlenecks.
- Xscape, iPronics, and PhotonDelta are reimagining the chip stack with energy-efficient, high-throughput photonics.
Meanwhile, China is doubling down. In 2024, researchers successfully integrated a laser light source into a silicon-based chip—solving a critical bottleneck. Their photonic pilot lines are already targeting 10,000 wafer capacity annually.
AI Is Fueling the Fire
AI is not only a use case—it’s a catalyst.
Today’s AI infrastructure can’t scale on off-the-shelf chips. Startups are raising hundreds of millions to build purpose-built semiconductors optimized for training, inference, or edge deployment.
Notable examples:
- Recogni: Raised $102M to develop inference chips for AI and automotive.
- Tenstorrent: Received $300M from Samsung and others to compete with Nvidia.
- Eliyan: Developing interconnect solutions that support chiplet designs—another growing trend.
As demand for AI compute grows, so does the market for custom semiconductors that balance performance, power, and price.
Follow the Capital: Where VCs Are Placing Their Bets
The semiconductor space isn’t just capital-intensive—it’s science-intensive. As a result, some of the most successful funds in the space combine deep tech expertise with long-term investing timelines.
Key players include:
- Silicon Catalyst Ventures: A rare VC + accelerator combo solely focused on semiconductor startups.
- NCI Waterstart (Europe): Invests in Series B companies like Scalinx, building power-efficient mixed-signal ICs.
- OMERS Ventures: Active in the UK and Silicon Valley, investing across seed to growth rounds.
- Earlybird VC (Germany): Invested in Quantum Diamonds, a quantum sensing platform applicable to semiconductor manufacturing.
Government funding is also flowing. In the U.S., the CHIPS Act is injecting $52B into the domestic semiconductor sector, though some argue it favours large incumbents. Meanwhile, China’s $40B national IC fund is catalyzing early-stage chip development at an unprecedented scale.
What This Means for VCs
Semiconductors may seem like old-school tech, but they’re now a critical enabler of everything investors care about: AI, data infrastructure, defense, energy efficiency, and national competitiveness. In a market where deep tech meets deep pockets, the opportunity is massive.
For venture investors, success will come from:
- Backing photonics and alternative architectures early
- Partnering with government grant programs and cross-border LPs
- Betting on startups that design (not just manufacture) chips tailored to frontier technologies
Just as every AI boom has its chip supplier, every next-gen tech wave will have its own silicon layer. And where there’s infrastructure being rebuilt, there’s room for venture capital to shape the future.
