AI Infrastructure Investment 'Polarization'… VC Runs Experiments, PE Controls Data Centers

Some analyses indicate that as the AI industry expands from software-centric to physical infrastructure such as data centers, power, and chips, the investment structure is restructuring into a division of labor between venture capital and private equity funds.

On the 17th, PitchBook released the report “Trends in Private Equity and Venture Capital in Advanced Computing,” which states that in the fourth quarter, venture capital (VC) accounted for 86% of total deals in the advanced computing sector, but only 16% of the investment amount. This is significantly below the past average of 29%, with most of the remaining funding coming from private equity (PE) investments.

The report diagnoses that this trend reflects the rapid expansion of AI infrastructure development. It explains that investment demand has surpassed purely software or large language models, extending into large-scale investments in physical infrastructure such as data centers, semiconductor manufacturing, and network equipment, transforming into structures requiring billions of dollars in capital. Based on this analysis, the role of PE investors capable of handling large-scale capital and long-term returns is expanding.

In the fourth quarter, VC investments in advanced computing totaled $53.5 billion, reaching the highest level in nearly five years. However, the number of deals was 293, slightly down from 304 in the previous quarter. Of these, 251 were VC deals, and only 42 were PE deals, but the total invested amount reached $44.9 billion, overwhelmingly dominating the funding landscape.

Particularly, data centers led the surge in investment. The report notes that PE investors are pouring large sums into this sector, with data center investments reaching $48.1 billion in the fourth quarter, a significant increase from $13.2 billion in the previous quarter, also marking a five-year high.

Large deals continued to occur. In October, an investor consortium including BlackRock and Abu Dhabi’s sovereign wealth fund MGX announced a $40 billion acquisition of data center operator Aligned Data Centers, focusing on AI workloads. Subsequently, in November, Blackstone invested $1.2 billion in Wolf Summit Energy, a company building power plants to meet data center demand.

On the other hand, the analysis suggests that VC continues to conduct technological experiments and service development in relatively smaller-scale fields. For example, Lambda, an AI GPU cloud service provider, raised $1.5 billion in November to offer specialized computing services based on limited-scale facilities.

The report comments that this trend is reshaping the market into a dual structure. It explains that one structure is emerging: VC leading experimental and service innovation, while PE plays the role of providing large-scale capital for physical infrastructure such as data centers.

The report concludes that AI is becoming an independent asset class for infrastructure, and this is the clearest signal that private market investors are actively participating in this sector.
