VAST Data says 14 customers committed USD $10 billion

VAST Data says 14 of its customers have made aggregate commitments of more than USD $10 billion for its software and related hardware. Four of those customers each committed more than USD $1 billion.

The commitments were made in the first three quarters of VAST's current fiscal year by a small subset of the more than 1,000 organisations it serves. Each of the 14 customers committed more than USD $100 million to VAST Data-based system buildouts.

The disclosure provides a measure of spending now flowing into data infrastructure for artificial intelligence training and inference. It also offers fresh detail on customer concentration at a company valued at USD $30 billion after a Series F funding round earlier this year that included NVIDIA.

VAST sells software for large-scale data environments, with platform hardware included in customer deployments. Its systems now support nine of the top 10 frontier AI labs, according to the company.

Supply planning

VAST also said it had structured agreements with supply chain partners to align more than 200 exabytes of flash capacity through 2029. The arrangements are intended to match expected demand from its largest customers and help users plan infrastructure purchases amid pressure on NAND flash supply.

NAND flash is a core component in enterprise storage systems used in data centres. Bringing new supply to market can take years because of the investment required in fabrication plants, making long-range planning important for suppliers and buyers when demand rises sharply.

According to VAST, the data capacity being delivered by its partners now represents a significant share of global NAND flash output for enterprise data centres. It did not disclose the financial terms of the supply agreements or identify the manufacturers involved.

Renen Hallak, founder and chief executive officer of VAST Data, linked the spending to broader changes in how AI infrastructure is being built. "Growth at this scale only happens when an entire industry is rebuilding at once. That's what the new AI stack is. It's being built for models and agents, not people and applications, and data sits at the centre of it. The companies building it at the largest scale, for people, agents and now robots, are choosing VAST to anchor it," Hallak said.

The latest figures come as investors and technology groups continue to channel large sums into AI-related computing, networking and storage. While graphics processing units have drawn much of the attention, storage and data systems are also seeing strong demand as companies assemble the infrastructure needed to train models, run inference workloads and manage growing volumes of data.

That has increased pressure across the semiconductor supply chain. Flash storage is widely used in data-intensive environments because operators need fast access to large datasets, and supply constraints can have knock-on effects on deployment timetables for cloud providers, AI labs, enterprises and public sector users.

Jeff Denworth, co-founder of VAST Data, said the company's supply planning was tied to customer requirements. "Planning for hundreds of exabytes isn't only about protecting our customers' growth projections. It's about keeping flash available to hundreds of clouds, so that every AI builder, not just the largest, has the capacity it needs to build and compete," Denworth said.

VAST did not name the 14 customers behind the commitments or break out how much of the aggregate total related to software versus hardware. It also did not say how much of the committed spending had already been converted into recognised revenue.

Even so, the figures point to a small number of buyers placing very large bets on storage and data architecture as AI infrastructure scales up. The largest disclosed group alone accounts for more than USD $10 billion in planned spending tied to VAST systems.
