Data center operator Switch raises $2 billion with Andreessen Horowitz

American data center operator Switch Inc. has begun raising a private funding round of approximately $2 billion, which is led by venture capital fund Andreessen Horowitz (a16z). This was reported on July 17, 2026 by Bloomberg, citing sources familiar with the deal.

What is known about the round

Details of the deal — Switch's final valuation, the composition of other investors, and the timeline for closing the round — are not yet being disclosed. Bloomberg sources describe the amount as an estimate: it could change following negotiations.

• Target round volume — approximately $2 billion
• The round is led by Andreessen Horowitz (a16z)
• Switch Inc. is an operator of large hyperscale data center campuses in the United States
• The deal is in its early stages, the company has not made official comments

Why investors are investing in data centers

Switch is known for large hyperscale data center campuses, including the SUPERNAP complex in Las Vegas, and has already undergone a change in ownership structure: in 2022, the company was taken private by investors DigitalBridge and IFM Investors for approximately $11 billion. Demand for computing power for training and inference of artificial intelligence models has grown sharply in recent years, and data center operators have become one of the most sought-after categories for venture capital and infrastructure investors — alongside chip manufacturers and energy companies.

Andreessen Horowitz actively invests in AI infrastructure — from chips to cloud platforms — and the fund's participation in the Switch round fits into this strategy: without sufficient data center capacity, further growth of the AI industry is physically limited by electricity, cooling, and space for servers.

What this means

The Switch round is another signal that money for AI infrastructure continues to flow as actively as into the models themselves: without data centers and energy, scaling AI services will come to a halt.
