Every AI Subscription Is a Ticking Time Bomb for Enterprise
AI subscriptions are currently subsidized, creating a significant gap between what enterprises pay and the actual costs, which will lead to financial shocks when prices adjust. Major providers like OpenAI and Anthropic are operating at a loss to capture market share, with reports indicating that companies could face bills between $15,000 and $40,000 a month for AI usage that currently costs only $1,000 at subscription rates.
