Lambda Seeks $4 Billion as SpaceX Pursues $40 Billion Nvidia Financing for AI Compute Expansion

AI infrastructure companies are turning to increasingly large pools of capital to secure the computing power needed for the next phase of artificial intelligence. Lambda is reportedly seeking up to $4 billion in a private funding round ahead of a potential 2027 IPO, while SpaceX is reportedly negotiating about $40 billion in financing to purchase Nvidia AI chips for its expanding computing infrastructure.

AI’s Next Bottleneck Is Becoming a Financing Problem

The race to build increasingly capable AI systems is no longer only about developing better models. It is increasingly about securing enough GPUs, data-center capacity, electricity, cooling and networking infrastructure to run those models at scale.

That shift is now producing financing deals measured in billions of dollars.

Two developments reported this week illustrate the scale of the capital being committed to AI infrastructure. Lambda, a specialized AI cloud provider, is seeking up to $4 billion in what could be its final private funding round before a planned public listing. At the same time, SpaceX is reportedly pursuing approximately $40 billion in debt financing to purchase Nvidia chips for its growing AI-computing operations.

The two companies are taking different financing routes, but both point toward the same underlying trend: access to advanced computing capacity is becoming a strategic asset.

Lambda Targets $4 Billion Before a Potential IPO

Lambda is reportedly seeking as much as $4 billion at a pre-money valuation of approximately $14.5 billion, according to reporting based on people familiar with the financing.

Blackstone and Coatue Management are reported to be leading the round. Lambda is targeting a 2027 IPO, although the timing remains dependent on execution and market conditions.

The proposed financing comes after a rapid expansion in Lambda’s infrastructure business.

According to investor information reviewed by The Wall Street Journal and reported by Reuters, Lambda’s backlog of unfilled orders increased from approximately $15 billion in June to $50 billion in September. A large portion of that increase appears to be associated with a $35 billion commitment from Anthropic.

That distinction matters. A large backlog indicates contracted or expected future demand, but it is not the same as revenue already recognized by the company.

Lambda has also been building a financing model around the physical infrastructure required to fulfill those commitments.

On October 1, the company announced a $1 billion investment-grade delayed-draw term loan designed to finance GPU infrastructure supporting three committed customer deployments across multiple data centers. The company said the financing is backed by contracted cash flows from two investment-grade customers.

Lambda’s investor materials say the company has raised more than $1.5 billion in equity and is developing AI infrastructure ranging from 5–75 MW sites to larger 75 MW-plus campuses.

SpaceX Is Taking the Debt Route

SpaceX’s reported financing plan is substantially larger.

According to Reuters, the company is negotiating to raise approximately $40 billion to purchase Nvidia AI chips. The proposed package is expected to include roughly $10 billion in bank loans and $30 billion in investment-grade debt, with Apollo Global Management expected to spearhead the financing and PIMCO among the institutions involved in discussions.

The financing reportedly remains under discussion, meaning the final amount, structure and terms could change.

The proposed borrowing reflects SpaceX’s increasingly large AI-computing ambitions.

SpaceX’s own materials now describe the company as developing orbital AI compute, while its broader AI infrastructure strategy includes large terrestrial data centers.

Nvidia has also publicly identified SpaceXAI as a major customer of its accelerated-computing platforms. In August, Nvidia announced that SpaceXAI would deploy its Vera CPU and Vera Rubin architecture as it scales toward gigawatts of AI-computing capacity.

Why Nvidia Chips Are at the Center

The financing stories are ultimately tied to one scarce resource: advanced computing hardware.

Modern AI training and inference require large clusters of accelerators capable of processing enormous numbers of mathematical operations in parallel. Nvidia’s GPUs and related computing platforms have become a central part of this infrastructure.

For companies such as Lambda and SpaceX, purchasing or deploying these systems is not equivalent to buying ordinary computer equipment.

The chips have to operate inside complete AI factories that also require power delivery, high-speed networking, storage, cooling systems, buildings and specialized operations.

That makes AI infrastructure highly capital-intensive.

Lambda’s recent financing demonstrates this directly. Its October $1 billion facility was structured so that capital can be drawn as infrastructure reaches commissioning milestones, matching financing with the deployment of physical computing capacity.

Compute Leasing Changes the Economics

The emerging model is also changing how AI companies obtain computing power.

Instead of every AI developer building its own massive data center, specialized infrastructure providers can purchase GPUs and lease computing capacity to AI companies.

Lambda operates within this model as an AI cloud provider. SpaceX is also expanding its computing business, with reports describing a growing strategy of selling or leasing AI compute capacity.

This creates an infrastructure-financing loop.

Investors and lenders provide capital → companies purchase GPUs and build data centers → AI customers commit to computing capacity → those contracts can help support further financing.

The model resembles infrastructure finance more than traditional software startup financing.

The Scale of Capital Is Becoming the Story

The proposed $4 billion Lambda round and $40 billion SpaceX financing also highlight how dramatically the economics of AI infrastructure have changed.

Software companies historically could scale without building enormous physical assets. Frontier AI requires something very different.

Each new generation of AI systems can require more computing power, while the infrastructure needed to provide that power can take years of planning, equipment procurement and energy development.

Morgan Stanley has estimated that AI infrastructure could require about $1.5 trillion of external financing by 2028, according to Reuters.

That figure illustrates why banks, private-equity firms, institutional investors and public markets are increasingly becoming part of the AI infrastructure ecosystem.

The Risk Behind the AI Infrastructure Boom

Large financing packages also create new financial risks.

A company that borrows heavily to purchase GPUs must generate enough cash flow from those assets to service its debt. That becomes particularly important because AI hardware evolves rapidly.

A data center financed around one generation of processors may eventually need substantial additional investment to remain competitive as newer accelerators deliver higher performance.

Demand is another variable.

Lambda’s reported $50 billion backlog demonstrates strong interest in AI computing, but its dependence on large customers also shows why infrastructure providers need financially durable customers and long-term contracts.

For SpaceX, the scale of the proposed financing creates an even larger balance-sheet question. The company would be using debt to acquire computing assets while simultaneously investing heavily in its broader AI and space ambitions.

From AI Models to AI Infrastructure

The latest financing activity suggests that the AI industry is entering a different phase.

The early wave of generative AI was dominated by model development, consumer applications and software platforms. The next stage increasingly depends on physical infrastructure: processors, data centers, electricity, cooling systems and networks.

Lambda’s planned financing and SpaceX’s reported Nvidia-chip financing therefore represent more than two isolated corporate fundraising stories.

They show how access to computing capacity itself is becoming an economic and strategic advantage.

The companies that can secure capital, power and advanced processors at scale may have an important advantage in determining how quickly they can expand AI services.

But the same scale creates a tougher question for investors and lenders: whether future AI demand will grow quickly enough to justify the enormous infrastructure commitments being made today.

For now, the capital race is accelerating alongside the computing race.

What Comes Next

Lambda’s proposed $4 billion round still needs to be completed, and its potential 2027 IPO remains subject to market conditions. SpaceX’s $40 billion financing is likewise a reported proposal rather than a completed transaction.

What is already clear is that AI infrastructure is moving into a capital-intensive era.

The competition is no longer simply to build the smartest model.

It is increasingly about who can secure the machines, energy, facilities and financing required to run intelligence at enormous scale.
