OpenAI slashes prices up to 90% to poach Anthropic customers

OpenAI is trading margins for market share, offering aggressive discounts to pull Anthropic's enterprise customers—and the strategy is working. Rippling, Replit, and DataCamp have shifted workloads, with reported cost cuts of 80–90%, while Anthropic's growth slowed from Q2 to Q3. Both vendors have cut list prices up to 80% since June, driven by efficiency gains and competitive pressure from Chinese rivals like DeepSeek.

• Rippling moved its coding workload from 16% OpenAI / 57% Anthropic to 52% OpenAI / 18% Anthropic.
• Replit switched after OpenAI offered more than 30% off a contract worth over $100 million annually.
• DataCamp CEO Jonathan Cornelissen reported 80–90% cost reductions; a US bank got ChatGPT seats doubled to 500 users at under $7 per seat instead of $20+.
• OpenAI cut GPT-5.6 Luna pricing by 80% on July 30, 2026, lowering input costs to $0.20/MTok.
• Anthropic launched Claude Sonnet 5 at $2/MTok input on June 30 and Claude Opus 5 at $5/MTok on July 24.

Bottom line If you're evaluating LLM vendors, lock in pricing now—this price war creates leverage for negotiation but may not last.
