Sam Altman told OpenAI employees during a town hall meeting on February 27, 2026, that the company was negotiating an agreement with the U.S. Department of Defense to deploy its AI models and tools. The critical aspect is not just the headline but the operational detail: OpenAI seeks to maintain its own "safety stack"—that is, technical, policy, and human controls between the model and end use—while also preventing the client from overriding model denials for specific tasks. Fortune reported that the contract was not finalized or signed yet, according to a source present at the meeting and a summary reviewed by the outlet.

This negotiation comes after a public fallout between the Pentagon and Anthropic. According to the same report, Anthropic refused to remove safeguards in its Claude model that restricted domestic mass surveillance and fully autonomous weapons, against pressures to enable use "for all legal purposes." Meanwhile, President Donald Trump ordered federal agencies to stop using Anthropic’s technology, providing a six-month exit window, and Secretary of Defense Pete Hegseth announced that the Department of Defense would designate Anthropic as a supply chain risk to national security, amplifying the impact beyond the government.

Hours later, Altman posted on X that OpenAI reached an agreement with the Department of Defense to deploy within its classified network, emphasizing two points: a ban on domestic mass surveillance and human accountability over the use of force, including autonomous weapons. The competitive clash is evident, but my reading is more measured: this episode reveals that in advanced AI, safeguards are no longer an ethical gesture, but rather a product control clause that defines who captures the margin, who assumes reputational risk, and who gets trapped in compliance costs.
When a Client Asks You to "Remove the Brakes", They’re Actually Seeking Control of the Margin
In high-risk services—and defense is by definition one—clients do not just purchase capability. They also buy responsibilities, and when they try to push usage limits, they are attempting to reconfigure the distribution of those responsibilities. In Anthropic’s case, the conflict reported by Fortune centered on the demand to lift safeguards related to domestic surveillance and autonomous weapons, while the Pentagon insisted on availability for "legal purposes." The consequence was twofold: a threat over a contract of up to $200 million and ultimately a political escalation ordering Anthropic out of federal agencies and designating it as a supply chain risk. (https://fortune.com/2026/02/27/openai-in-talks-with-pentagon-after-anthropic-blowup/)
From a financial architecture standpoint, I translate this as follows: if a client manages to pressure the provider into removing product limits, the provider shifts from selling a tool to subcontracting the risk. And risk, sooner or later, translates into cost. Legal cost, compliance cost, internal security cost, talent cost, insurance premium cost, and commercial cost in other segments. No need to invent figures: just understand the mechanics. In AI, the dominant variable cost is computation. If uncertain costs are added due to extreme or politically sensitive uses, the margin stops being a number and becomes a bet.
Thus lies the relevance of Altman’s message to the staff: OpenAI negotiates to maintain its "safety stack" and prevent the client from imposing overrides on model denials. This serves as a way of telling the buyer: the service is provided under technical conditions that preserve the product’s perimeter. This protects the company but also stabilizes the economics of the contract by reducing the likelihood of the agreement devolving into ad hoc requirements, operational exceptions, and escalating human support that erodes margins.
Defense as Anchor Client: Predictable Flow in Exchange for Strict Restrictions
OpenAI comes to this table within a context where the sector seeks to monetize foundational models that are capital and compute-intensive. When the product has high variable costs, the typical temptation is to pursue volume. However, in government and defense, volume doesn’t resemble mass consumption: it looks like contracts with large tickets, slow purchasing cycles, and security demands that convert part of the cost into fixed.
The decisive point of Fortune’s briefing is that Altman reportedly specified deployment limits, including that the use would be in cloud environments and not on edge systems like planes or drones. Additionally, the agreement mentioned on X would focus on deployment within a classified network. (https://fortune.com/2026/02/27/openai-in-talks-with-pentagon-after-anthropic-blowup/) This scope matters as it defines the cost curve. Deploying in a classified network is not trivial, but delineating the perimeter reduces combinatorial issues: fewer extreme integrations, less need for critical latency scenarios, and reduced necessity for certifications associated with operational hardware.
From a financial perspective, a defense anchor client can play two roles. First, it provides recurring high-quality revenues, typically less sensitive to the economic cycle than a consumer segment. Second, it acts as a validator for regulated B2B sales. But the hidden cost is the risk of being captured by requirements that expand fixed costs: dedicated teams, audits, incident response, and rigid contractual governance.
Thus, it is crucial for OpenAI to seek to maintain its "safety stack". This is its way of limiting “scope creep” and protecting its cost structure. A large contract that grows in complexity faster than revenue is a contract that makes you appear large while making you fragile.
The Void Left by Anthropic is Not Just Commercial: It’s a Power Reordering
Until this episode, Anthropic was, according to Fortune, the only major commercial provider with approved models for Pentagon use through an alliance with Palantir. (https://fortune.com/2026/02/27/openai-in-talks-with-pentagon-after-anthropic-blowup/) This gave it an asymmetric advantage: being “the authorized” within a buyer with enormous budgets.
The political intervention changes the playing field. The presidential order to cease the use of Anthropic and the threat of designation as a supply chain risk create a secondary effect: they increase the opportunity cost for any entity that partners commercially with Anthropic in defense-related realms. I need not speculate about the legal outcome; simply observing the incentive is sufficient: the public buyer seeks to discipline the private provider.
In this context, OpenAI emerges as the natural substitute, but with a strategic difference: it enters the segment with an explicit message of mutual “respect” for AI security principles, including prohibitions on domestic mass surveillance and the requirement for human responsibility in the use of force. (https://fortune.com/2026/02/27/openai-in-talks-with-pentagon-after-anthropic-blowup/) Translated into negotiation terms, this means construing a contract where the company retains part of product control, and the client maintains mission control, but without making AI an unrestricted system.
This balance has a competitive reading: if the government accepts that OpenAI can maintain its security layer, then “capacity” ceases to be the sole criterion. It moves to importance who can offer capacity within a framework of control that the buyer can tolerate politically. In regulated markets, that tolerance ultimately defines the real size of the accessible market.
The Simple Math Behind the "Safety Stack": Protecting the Margin by Protecting the Perimeter
A financial leader should not remain only in the abstract debate. The operational question is what variable is being attempted to control.
In an AI modeling business, the marginal cost per use moves with computation, and the quality cost moves with security, monitoring, and support. If the client can demand exceptions and override denials, two effects unfold:
1) Increased support cost: more incidents, more human escalation, more policy revisions, and more internal audits.
2) Degradation of future sales: a single episode can close doors in corporate sectors that also pay well and do not wish to be associated with controversial uses.
From this logic, maintaining the "safety stack" is a way to convert part of the risk into a product rule. It’s not altruism; it’s control of cost variability. And controlling variability is, at its core, defending margin.
The figure of $200 million for the contract in dispute with Anthropic also provides a scale. (https://fortune.com/2026/02/27/openai-in-talks-with-pentagon-after-anthropic-blowup/) Such an agreement can finance infrastructure, security, and dedicated teams. However, it is only good business if it doesn’t become a pit of rising costs due to scope changes. The risk from government contracts isn’t that they pay little; it’s that they pay well while demanding you operate as if your structure were that of a traditional defense contractor.
OpenAI’s move suggests learning: negotiating from the outset the deployment perimeter, the control of safeguards, and the non-obligation to override denials. That written “no” in the contract is the financial equivalent of setting limits on variable costs and reputational costs.
The Direction is Clear: Win the Contract Without Selling the Product’s Steering Wheel
This episode leaves a useful signal for any CEO or CFO selling critical mission technology to large institutional buyers. The negotiation is not defined solely by price and volume but by who controls the operating system.
Anthropic, according to the report, defended red lines and now faces a federal exit process and a potential designation as a supply chain risk, which they announced they would contest in court. (https://fortune.com/2026/02/27/openai-in-talks-with-pentagon-after-anthropic-blowup/) OpenAI, on the other hand, positions itself to capture the vacant space while attempting to preserve its own controls and limit deployment to contexts where operational complexity is manageable.
Financially, the lesson is clear. A large contract only strengthens the company if it comes with limits that preserve margin and reduce cost variance. The ideal agreement is not the one that makes the most headlines but the one that defines the usage perimeter, avoids exceptions, and converts risk into operational rules. In the end, the company that maintains control is the one that can finance itself with real and repeatable revenues, as client money remains the only validation ensuring the company’s survival and control.
