Microsoft and Uber are grappling with AI budget overruns due to extensive use of Anthropic's Claude Code, according to BeInCrypto. Microsoft has canceled most internal Claude Code licenses, with its Experiences and Devices division ending access by June 30, 2026, after unsustainable token-based billing. Uber's Chief Technology Officer, Praveen Neppalli Naga, revealed the company exhausted its 2026 AI budget by April, deploying Claude Code to 5,000 engineers. Industry data shows 85% of companies miss AI cost forecasts, highlighting a broader financial squeeze.
