AI Concentration Crisis: When Model Providers Become Systemic Risks

A brief public suggestion in late 2025 that a prominent AI company might seek a formal partnership with government agencies forced a candid conversation about the sector’s growing systemic weight. That moment revealed an industry trajectory many warned about: rapid winner-take-most dynamics driven by network effects and concentrated investment. Unlike prior platform disputes where users could switch apps, modern AI models are being woven into the fabric of business processes, research, and public services, making displacement an infrastructural challenge rather than a product choice. The magnitude of spending is staggering: global AI infrastructure expenditures hit roughly $1.5 trillion in 2025 and are projected to expand by about $500 billion the following year, directing vast resources through a small set of providers. By contrast, decentralized and alternative projects attracted roughly $436 million in 2024, a tiny fraction of centralized flows and insufficient to guarantee competitive parity. Technical obstacles compound the market problem: decentralized systems must close performance gaps while delivering sufficient coordination, governance, and reliability for enterprise and regulatory use. Historical antitrust playbooks offer limited guidance because breaking up consumer-facing services is different from disentangling embedded infrastructure and standards adopted across industries. Consumer and organizational demand for privacy-focused options exists, but adoption curves show recapturing dominant share can take many years, if it happens at all. The upshot is a policy and engineering race: build interoperable protocols, fund alternative compute and data layers, and clarify regulatory thresholds before one or two architectures become de facto global standards. If policymakers delay, remedies will be technically blunt and politically fraught, leaving regulators reactive rather than preventive. The analysis points to immediate priorities: accelerate public investments in open infrastructure, mandate portability and auditability where feasible, and treat infrastructure concentration as a systemic risk with cross-sector consequences.
