OpenAI Enters the Military Sector: Technological Innovation, Ethical Dilemmas, and the Ripple Effects on Capital Markets

Recently, OpenAI reached an agreement with the U.S. Department of Defense to deploy its AI models to the Pentagon's classified cloud network, a move that has triggered intense shocks across the global technology sector, ethical fields, and capital markets. Although OpenAI emphasizes that the collaboration adheres to safety principles such as “prohibiting mass surveillance” and “human control over lethal decision-making,” the “Boycott ChatGPT” campaign initiated by over four million people, fluctuations in AI giant stock prices, and the escalation of EU regulatory scrutiny all reveal deep-seated contradictions in the process of technological militarization.

The core controversy of the collaboration lies in the role boundaries of AI in warfare scenarios. Critics point out that AI involvement may lower the threshold for military decision-making: for example, NATO’s “Athena” system once demonstrated the ability to generate ten sets of operational plans in five minutes, whereas traditional manual planning takes several days. While this efficiency gain is regarded as a “technological advancement,” it may also lead to conflict escalation—when AI shortens the chain from intelligence analysis to action execution, human prudence in the use of force may be diluted by algorithmic speed.

Even more severe is the risk of technological misuse. OpenAI employs a closed, paid model, and after its deployment on the U.S. military’s classified network, the international community finds it difficult to monitor the technology’s practical applications. Although the agreement prohibits “fully autonomous weapon systems,” security tests in 2025 showed that GPT-4.1 once provided methods for weaponizing anthrax, exposing the potential for the model to output dangerous content under certain inducements. If such technology flows into the military domain, it could trigger an “algorithmic arms race” or even give rise to lethal systems beyond human control.

Ethical controversies arising from cooperation quickly spread to the capital market. Oracle's stock plunged 7.7% in a single day after it canceled plans to expand its data center in Texas with OpenAI. Behind this decision were delayed financing negotiations, frequent changes in OpenAI's demand forecasts, and project reliability issues — earlier this year, the data center was offline for several consecutive days due to a liquid cooling equipment failure. The market is concerned that the high risks and uncertainties of military AI projects could drag down long-term corporate profitability expectations.

Meanwhile, changes in user behavior are intensifying market volatility. OpenAI competitor Anthropic’s AI chatbot Claude, after the cooperation news was announced, for the first time surpassed ChatGPT in download numbers in the U.S., showing a shift in user preference toward ‘non-militarized AI.’ The capital market’s sensitive reaction reflects a reality: in the interplay between technology and ethics, the market tends to avoid risks rather than chase short-term technological gains.

Faced with the wave of AI militarization, the European Union is accelerating the construction of a regulatory framework. The 2025 'Defense and Artificial Intelligence' report has called for a ban on lethal autonomous weapons and promotes global cooperative regulation. This OpenAI cooperation incident could become a catalyst for the EU to strengthen scrutiny — if the EU incorporates military AI applications into the risk classification system of the 'Artificial Intelligence Act,' OpenAI’s model deployment and cross-border data flows in the European market could face strict restrictions.

The EU's regulatory logic has a demonstration effect. Its 'human-centered' governance principle emphasizes human ultimate control over the use of force, contrasting with the 'human-in-the-loop' clause in the OpenAI cooperation agreement. If the EU legislates to clearly define red lines for military AI, it could compel global tech companies to reassess technological boundaries, and even pressure the U.S. to adjust its policies — after all, the EU market accounts for nearly one-third of global AI revenue, and its regulatory influence cannot be ignored.

OpenAI’s cooperation with the U.S. military is, in essence, a strategic weighing of options under geopolitical pressure — refusing defense orders risks missing out on dominating technological iterations, but such controversies also warn the industry: technological advancement cannot be divorced from ethical constraints.

Future AI militarization requires the establishment of three mechanisms: a transparency mechanism (third-party audits to trace use), accountability (clearly define legal responsibility for algorithm errors), and a global governance framework (U.N.-led ban on lethal autonomous weapons). Only in this way can technology avoid becoming a 'conflict accelerator' and truly serve peace.

In this turbulence of technology, ethics, and markets, OpenAI’s choice may merely be the prelude. As AI leaves the laboratory and heads to the battlefield, humanity will ultimately have to confront a core question: can we draw unbreachable boundaries for the double-edged sword of technology?
