Cerebras’ IPO filings show that G42 was far more than an investor. The Abu Dhabi-based AI group was simultaneously a major Cerebras customer, infrastructure-services buyer, prepayment provider, proposed equity investor and source of U.S. national-security scrutiny.
That relationship helped Cerebras finance and deploy large AI-computing systems, but it also created customer-concentration, accounting, ownership and geopolitical risks. Later filings show that G42’s share of revenue fell sharply, although Cerebras remained dependent on a small number of strategic counterparties.
The relationship was bigger than an investment
Cerebras is a U.S. AI-computing company built around wafer-scale processing technology. G42 is an Abu Dhabi-based AI and technology group with interests including cloud computing, data centers, AI services and research.

Cerebras’ original September 2024 S-1 described a relationship spanning several different categories:
#1 Best Overall
- A USB accessory that brings machine learning inferencing to existing systems. Works with Raspberry Pi and other Linux systems
- Performs high-speed ML inferencing: the on-board edge TPU Coprocessor is capable of performing 4 trillion operations (tera-operations) per second (tops), using 0.5 watts for each tops (2 tops per watt). For example, it can execute state-of-the-art mobile vision models such as mobilenet V2 AT 400 FPS, in a power efficient manner
- Works with Debian Linux: connects to any debian-based Linux system with an included USB 3.0 Type-C cable
- Supports tensorflow Lite: no need to build models from the ground up. Tensorflow Lite models can be compiled to run on the edge TPE
- Supports automl vision edge: easily build and deploy fast, high-accuracy custom image classification models to your device with automl vision edge
- Customer: G42 agreed to purchase Cerebras computing systems and related products.
- Infrastructure partner: G42 also contracted for power, space, communications, operation and management services.
- Prepayment provider: G42 advanced $300 million to support manufacturing and infrastructure procurement.
- Proposed investor: An affiliated entity planned to purchase approximately $335 million of Cerebras preferred stock, subject to regulatory approval.
- Regulatory counterparty: The proposed investment became the subject of a joint voluntary review by the Committee on Foreign Investment in the United States, or CFIUS.
The filings therefore describe a commercial and financial connection—not proof that G42 controlled Cerebras or misused its technology.
What G42 agreed to buy
The headline figures refer to several agreements and should not be treated as one simple payment or as revenue already recognized by Cerebras.
| Arrangement | Disclosed amount | What it covered |
|---|---|---|
| September 2023 framework agreement | Approximately $389 million | Purchase orders for high-performance computing systems, installation, support and software updates. |
| September 2023 master-services agreement | Approximately $88.8 million | Power, space, communications, operation and management of systems purchased by G42. |
| April 2024 letter of award | At least $300 million | Additional intended purchases of Cerebras products and services. |
| May 2024 agreement | Approximately $1.43 billion | A broader aggregate commitment for products and services, according to the 2024 S-1. |
A purchase commitment is not the same as cash received, units delivered or revenue recognized. Actual revenue can depend on manufacturing, installation, acceptance, deployment schedules, service periods and other contractual conditions.

G42’s $300 million prepayment, received in May 2024, was particularly important because it helped Cerebras fund the physical expansion of its business. Cerebras said it would use the money to pay third-party vendors manufacturing infrastructure.
The arrangement also contained protections and risks:
Rank #2
- High-Performance AI Processing: The MX3 is designed to handle the most demanding AI computer vision workloads, delivering exceptional performance and efficiency.
- Flexible Integration: The MX3 can be easily integrated into your existing systems via its M.2 M-key form factor and support for Linux operating systems.
- Energy Efficient: The MX3 is designed to provide high performance while minimizing power consumption.
- Comprehensive Software Development Kit (SDK): The MX3 is supported by a comprehensive SDK that simplifies development and deployment.
- Hardware compatability: The MX3 is compatible with the PCI-SIG M.2 M-key 2280 Specification. It can be used with the Raspberry Pi 5 with a M-key 2280 HAT.
- If G42 failed to issue the expected purchase orders, any unspent amount was payable to G42 on demand.
- Rights to inventory purchased with the prepayment would transfer to G42.
- Cerebras gained funding for production and deployment without relying entirely on its own balance sheet.
- Cerebras also took on execution, delivery and potential repayment risk if planned deployments did not proceed.
This makes the prepayment different from ordinary equity financing. It was tied to a commercial transaction, but it still helped bridge the capital requirements of producing and deploying unusually large AI systems.
The proposed equity investment and the ownership questions
The original arrangement contemplated an approximately $335 million purchase of Cerebras preferred stock by an entity affiliated with Group 42 Holding Ltd. The agreement also gave G42 an option to buy preferred shares at a 17.5% discount if it purchased between $500 million and $5 billion of additional products and services.
Those terms must be separated from other forms of exposure:
- Proposed shares: The $335 million preferred-stock purchase required regulatory approval and was not simply the same as completed ownership.
- Commercial commitments: The $1.43 billion figure represented products and services, not equity.
- Options: An option creates a right to buy securities, not necessarily an immediate shareholding.
- Warrants: Warrants can result in shares only when exercised and should not automatically be counted as existing common-stock ownership.
- Non-voting securities: A later restructuring involving non-voting preferred stock could limit governance rights without eliminating economic or regulatory significance.
Cerebras’ later filing says the parties agreed in principle during the first quarter of 2025 to remove G42 as a party to the original preferred-stock agreement and pursue a new arrangement involving non-voting preferred stock if the purchase occurred. The filing also says the original transaction could terminate if it did not close by April 15, 2025.
Why CFIUS became involved
Cerebras and G42 filed a joint voluntary notice with CFIUS in July 2024 concerning the planned equity purchase. The 2024 filing said the review remained pending through the end of that year, contributing to uncertainty around the transaction and Cerebras’ IPO timetable.
The relevant concern was not merely that a foreign company might own shares. Cerebras sells advanced AI-computing systems, while G42 operates in a strategically sensitive AI ecosystem in the United Arab Emirates. The proposed relationship also involved access to systems, data-center deployment, infrastructure and operational services.
U.S. scrutiny of advanced semiconductors and AI infrastructure makes that combination politically and strategically significant. However, the filings do not establish that G42 misused Cerebras technology, violated national-security rules or was formally blocked by CFIUS. The defensible description is that the transaction was reviewed, remained unresolved for a period and was later restructured in filings that contemplated non-voting securities.
The accounting effect: a $401.3 million remeasurement loss
The financial consequences of the arrangement were also significant. Cerebras’ May 2026 S-1/A reported:
- $237.8 million net income in 2025
- $481.6 million net loss in 2024
- $401.3 million of remeasurement loss in 2024 related to the G42 forward-contract liability
The filing reported no comparable remeasurement loss for 2025. A fair-value remeasurement can materially change reported profit or loss even when it is not the same as an operating cash expense in the period being discussed.
That does not make the accounting treatment “fake” or fraudulent. It means readers should separate operating performance from changes in the value of financing-related instruments. Cerebras’ sharp swing from a 2024 loss to 2025 income should not be interpreted as a pure measure of recurring operating profitability without examining these effects.
Rank #4
G42’s revenue importance declined—but concentration did not disappear
The 2026 filing materially changes the picture presented by the original IPO paperwork. G42 accounted for 85% of Cerebras’ revenue in 2024, but its share fell to 24% in 2025.
That is an important reduction in dependence on G42 specifically. It is not, however, the same as broad diversification. MBZUAI accounted for 62% of Cerebras’ 2025 revenue, meaning a different strategic customer became the largest disclosed source of revenue.
The practical lesson is that concentration may have shifted rather than vanished. Investors should examine:
- How many customers generate most of the company’s revenue.
- Whether contracts are recurring or tied to one-time deployments.
- Payment terms, acceptance milestones and cancellation rights.
- Whether customers also provide financing, infrastructure or other support.
- How quickly Cerebras can replace a large customer if a deployment is delayed or cancelled.
A customer can be commercially valuable while still creating counterparty and regulatory risk. Conversely, a lower percentage can reflect growth from another large customer rather than a broad base of independent buyers.

G42 received and exercised warrants
Cerebras disclosed a warrant for up to 1,857,516 Class N shares, issued in December 2025 and exercised in January 2026. It also disclosed another warrant for up to 1,655,975 shares, issued and exercised in April 2026.
These instruments should be analyzed separately from the original proposed preferred-stock investment. The filings establish the warrant amounts and exercise dates, but the numbers alone do not establish what percentage of Cerebras G42 owned without reference to the applicable share-count tables.
OpenAI became another major counterparty
Cerebras also disclosed major OpenAI-related arrangements, including a master relationship agreement effective December 24, 2025. The disclosed plan called for OpenAI-related capacity to reach 750 megawatts by the end of 2028, subject to the agreement’s conditions and deployment schedule.
Do these 3 things before closing this tab:

It does, however, show why the 2026 story is broader than the original G42 headline: Cerebras was building relationships with additional major AI customers and infrastructure partners.
The business benefits and risks of the G42 model
Why the relationship helped Cerebras
- It provided an early anchor customer for large-scale deployments.
- The prepayment helped fund manufacturing and infrastructure procurement.
- It created a route into Gulf-region AI and data-center markets.
- It potentially accelerated real-world utilization of Cerebras systems.
- It reduced the need for Cerebras to finance every deployment independently.
Why the structure was risky
- Customer concentration: G42 represented 85% of revenue in 2024.
- Counterparty concentration: One organization was connected to purchases, investment, prepayments and infrastructure services.
- Regulatory exposure: The proposed equity transaction drew CFIUS scrutiny.
- Execution risk: Large commitments depended on deployment schedules, capacity, financing and acceptance milestones.
- Accounting volatility: The forward-contract liability produced a $401.3 million remeasurement loss in 2024.
- Pricing and bargaining risk: A strategically important customer with financing influence may receive favorable pricing or securities terms.
- Geopolitical exposure: Cerebras’ growth became linked to U.S.–UAE technology policy and export-control concerns.
What investors should take from the filings
The most important question is not simply whether G42 invested in Cerebras. It is how Cerebras’ growth model worked.
The filings show a company using large strategic relationships to coordinate demand, financing, infrastructure and deployment. That can accelerate growth in a capital-intensive AI market. It can also make the company vulnerable when one relationship changes, when regulators intervene or when accounting values move sharply.
By 2025, Cerebras had reduced its revenue dependence on G42 and added significant OpenAI-related business. That is constructive, but the 62% MBZUAI figure shows that the company still relied heavily on a small number of counterparties. The central risk therefore evolved from “dependence on G42” to a broader question: can Cerebras build a sufficiently wide and recurring customer base beyond a handful of strategic AI organizations?
