Senate Bill Targets Pentagon Cloud and AI Vendor Lock-In

Why the bill was introduced

The Department of Defense (DoD) has been leaning heavily on commercial cloud providers through multi-billion-dollar initiatives such as the Joint Warfighting Cloud Capability (JWCC), according to the analysis, written by Syona Kadidal of Purdue University's Governance and Responsible AI Lab (GRAIL) as part of the AI Policy Corner series.

Senators Elizabeth Warren and Eric Schmitt first introduced the Protecting AI and Cloud Competition in Defense Act of 2024 (S.5436) to counter dependence on a single vendor and to open procurement to emerging startups. The article says momentum grew the following year, when the White House issued directives to drive efficient acquisition of artificial intelligence while explicitly warning federal agencies against costly dependencies on a single vendor. The bill was reintroduced in both chambers on May 15, 2025.

What the bill would require

The bill mandates a strictly competitive award process for any cloud computing, data infrastructure or foundation model provider that has entered into DoD contracts totaling $50 million or more over the previous five fiscal years. The article says this would help small businesses and new startups enter the defense market.

• Multi-cloud and open systems: department leaders would be directed to prioritize multi-cloud technology and modular open-systems approaches to improve competition and cost efficiency.
• Interconnectivity: by restricting single-vendor dependence, the DoD aims to let smaller tech companies integrate their tools directly into the military's network, so they are not boxed out by Big Tech companies.
• Data protection: the Pentagon's Chief Digital and Artificial Intelligence Office (CDAO) would have to update the Defense Federal Acquisition Regulation Supplement (DFARS) so that government-related data provided for AI development is not disclosed or used without authorization. Military data stored on a vendor's system must also be strictly protected.
• Penalties: vendors that fail to comply would face fines, penalties or termination of contract.

Concerns about market concentration

The author argues the bill may face structural limits. The broader cloud computing market is a $600 billion industry dominated by three private companies: Amazon, Microsoft and Alphabet. Because the DoD buys from the same commercial market, the article says, it faces the same anti-competitive barriers as any consumer. Tech giants charge penalty fees to move data and make switching systems difficult.

Exclusivity contracts are another risk. They may constrain AI developers to a single cloud provider and prevent them from offering their models on rival platforms, which could undermine the bill's push for open competition and interconnectivity. The article also notes that partnerships between major cloud providers and AI developers often function as "de facto mergers." A 2025 Federal Trade Commission report stated that these arrangements allow Big Tech companies to consolidate talent and resources while bypassing traditional antitrust scrutiny, according to the analysis.

Legislative status and what it means

Warren and Schmitt continue to lead the effort in the Senate. Representatives Pat Fallon, Sara Jacobs and Chris Deluzio introduced the companion bill in the House. The source does not report any vote or further progress.

The author calls the act a strong effort to keep the DoD from significant and costly dependencies on one technology vendor. Yet she concludes that mandating competitive bidding for contracts exceeding $50 million might not be a complete fix. In her view, procurement reforms must keep contending with data-transfer penalties, opaque pricing and the vertical integration of today's cloud computing market.
