AI Markets Group (AIMG) published a Special Report sizing the AI governance platforms market at $3.6 billion in 2027, rising to $12.5 billion by 2030, a 51% CAGR, with enforcement rather than policy as the binding constraint. According to the report, 96.5% of large US public companies have adopted AI governance policies, yet 46.3% of senior AI executives report bypasses; 98% of organizations maintain AI data-access policies, while 86% of IT leaders saw AI tools or agents access sensitive data beyond their intended scope last year. AIMG Chair Peyman Mestchian said governance is becoming a control plane and vendors that own the enforcement points will capture most of the value. Key findings include that most spend is embedded, with stand-alone platforms reaching $1.57 billion by 2030 and the rest bought within hyperscaler, security and identity platforms; agent governance and non-human identity grows fastest at 81% a year; the EU Digital Omnibus delayed high-risk deadlines to December 2027 and August 2028 but did not remove them; AIMG expects most stand-alone specialists to be acquired or merged by 2028; and spend per enterprise more than doubles from $1.5 million in 2027 to $3.4 million by 2030 for adopting Global 2000 firms.
