By every measure, U.S. companies are winning on AI adoption—but a series of high-profile snafus shows they’re getting pummeled by costs

U.S. firms are rapidly adopting AI—around half of U.S. workers now use AI tools—but rising usage is producing hefty, sometimes unexpected costs that are weighing on corporate budgets and near-term returns. Companies from startups to tech giants are incurring large token bills, proprietary platform fees and costly deployment mistakes (e.g., Uber burning through its 2026 AI coding budget early), prompting some firms to ration or tighten AI usage. While research shows modest productivity gains and potential long-run economic upside, measurable ROI remains limited, leaving investors to weigh stronger AI-driven demand for technology (supporting the US Tech 100) against pressure on corporate margins and possible short-term cost-driven headwinds.
