What Is a Neocloud? The GPU Clouds Powering the AI Boom

Training and running modern AI models takes a huge amount of computing power, almost all of it from graphics processing units (GPUs). For most of the past decade, renting servers meant going to one of the "hyperscalers": Amazon Web Services, Microsoft Azure or Google Cloud. When the ChatGPT boom set off a scramble for GPUs, a new kind of company stepped in to meet the demand. These are the neoclouds.

Neoclouds are specialist cloud providers that do one thing: rent out GPU capacity for AI training and inference (running a trained model to answer requests). They have gone from unknown startups to listed companies with contracts worth billions of dollars, and their roots in crypto run deep. CoreWeave began as an Ethereum miner, and a wave of Bitcoin miners is now turning its power-hungry sites into AI data centers.

This guide covers what neoclouds are, how they work, who the main players are, and why their shares were sold off hard in October 2026.

What is a neocloud?

A neocloud is an AI-focused infrastructure-as-a-service (IaaS) provider. A hyperscaler sells hundreds of services, from databases to email hosting. A neocloud mostly sells access to large clusters of high-end GPUs, plus the networking, storage and software needed to run AI workloads on them. CNBC describes them as businesses that offer access to the GPUs powering artificial intelligence as a service.

The best-known neoclouds are:

• CoreWeave (Nasdaq: CRWV): backed by Nvidia, and the largest pure-play neocloud. It listed in March 2025.
• Nebius Group (Nasdaq: NBIS): based in Amsterdam, and formed from the international business of Russian tech giant Yandex.
• Lambda, Crusoe and Fluidstack: privately held GPU cloud providers, though Lambda is raising a final funding round ahead of a planned IPO.
• IREN: a Bitcoin miner turned AI host that now runs its own AI cloud.

Neoclouds are companies, not blockchains, so they don't issue a native token. Their shares trade on traditional stock exchanges.

How does a neocloud work?

The neocloud model comes down to three scarce resources: chips, power and capital.

1. 𓇲 Chips. Neoclouds buy large numbers of Nvidia GPUs and network them into clusters built for AI. Being first in line for new Nvidia systems is a big selling point.
2. 🔋 Power and space. AI clusters need hundreds of megawatts of electricity plus liquid cooling. Neoclouds either build their own data centers or lease "powered shells" from site owners, including Bitcoin miners turned AI hosts.
3. 💰 Capital. GPUs are expensive and lose value quickly. Neoclouds usually pay for them with debt, often backed by the chips themselves and by long-term customer contracts.

Customers such as AI labs, Big Tech firms and startups sign multi-year agreements for reserved capacity, or pay by the hour on demand. The neocloud earns the difference between what the GPUs bring in and what they cost to buy, power and finance.

The weak point is depreciation. In its second-quarter 2026 results, CoreWeave reported depreciation and amortization of nearly $1.4 billion against revenue of about $2.6 billion, while Nebius booked about $260 million against revenue of $582 million.

What's so special about neoclouds?

Neoclouds compete on speed and focus. Hyperscalers split their GPUs between many services, including their own AI products. Neoclouds can deliver large, dedicated clusters quickly, and they tune their software for AI rather than general-purpose computing. Some of their biggest customers are the hyperscalers themselves, which rent neocloud capacity when their own data centers can't keep up.

The sector also gives Bitcoin miners a second life. In the two years to July 2026, miners contracted roughly 7 gigawatts of power capacity across 19 deals worth more than $135 billion to hyperscalers, neoclouds and chipmakers, according to Bernstein. That is less than a quarter of the 30 GW the miners have in their planned power pipeline. The asset that matters is power: miners already had land, grid connections and permits, which can take years to obtain.

Who's working with neoclouds?

• 🤖 Microsoft: a major buyer of neocloud capacity, including a roughly $9.7 billion, five-year GPU cloud contract with IREN.
• ☁️ Amazon Web Services: signed a 15-year, roughly $5.5 billion lease with Cipher, a Bitcoin miner turned AI host, for AI capacity.
• 🔍 Google: guarantees Fluidstack's lease payments on sites run by TeraWulf and Cipher.
• 🧠 Anthropic: an AI lab leasing capacity from TeraWulf and, via Fluidstack, from Hut 8.
• 🎮 Nvidia: the main chip supplier to neoclouds, and an investor in CoreWeave.

Is there a neocloud token?

No. Neoclouds are conventional companies. The closest crypto equivalent is decentralized physical infrastructure networks (DePIN) such as Render, Akash and io.net. These use tokens to pay for GPU compute and to reward the people who provide it. They aim at the same market but run on a peer-to-peer model instead of company-owned data centers.

Where to buy neocloud stocks

CoreWeave (CRWV), Nebius (NBIS) and IREN (IREN) trade on the Nasdaq and are available through mainstream brokerages. Several other listed Bitcoin miners turned AI hosts, including TeraWulf, Cipher, Hut 8 and Core Scientific, give exposure to the AI hosting side of the business. Crypto-native compute tokens such as Render (RENDER) trade on major exchanges. Treat all of these as high-risk, volatile assets.

The future of neoclouds

The sector is under heavy pressure. On October 14, 2026, Gartner predicted that "cost pressure and a lack of a differentiating business model" will force more than 80% of neocloud providers to stop operating independently by 2030. It also estimated that more than $3.5 trillion of AI infrastructure spending could be exposed to impairment by the end of 2030 if AI providers keep spending at their current pace.

Credit markets have grown nervous too. By October 21, 2026, CoreWeave's unsecured debt was yielding about 15%, and the cost of insuring its bonds against default had risen 30% in a month. Its shares were down 29% for October, leaving the company valued at about $34 billion, against a peak of about $90 billion in 2025. Nebius fell 27% over the same period, even though it carries far less net debt, and IREN fell 32%.

The bull case is still alive. CoreWeave co-founder Brannin McBee said nearly all of the company's 2027 capacity is already sold, with contracts running into 2028 and beyond. Whether neoclouds stay independent or end up owned by bigger players, demand for AI compute remains high. The open question is whether these companies can earn enough from it to pay back their debts.
