Abstract:
OpenAI is initiating a strategic realignment focused on capturing increased enterprise market share in 2026, driven by significant usage share erosion to competitors. This push is underpinned by a leadership change, appointing former executive Barret Zoph to head the enterprise sales effort. Despite being an early entrant with its ChatGPT Enterprise product (2023) and claiming over 5 million users, OpenAI's market share in enterprise Large Language Model (LLM) usage plummeted from 50% in 2023 to 27% by the end of 2025. Competitor Anthropic currently holds the dominant position with 40% market share, while Google's Gemini maintains stable adoption at 21%. This focus on enterprise growth is explicit company strategy, as confirmed by CFO Sarah Friar and evidenced by a recently expanded partnership with ServiceNow.
