According to The Information, OpenAI’s 80% price cut on Luna led to a roughly 10–13x increase in usage. The report links this result to Anthropic’s prospects: its attractiveness to investors partly depends on the ability to sustain high prices while growing revenue quickly. Cheaper models from competitors could increase pressure on Anthropic’s pricing and make it harder to maintain high margins ahead of its planned IPO.

Anthropic filed confidentially for its IPO in June 2026, with a listing expected in October. OpenAI’s aggressive pricing strategy, particularly on its cheapest model Luna, could erode the perceived pricing power that underpins Anthropic’s revenue growth narrative.
