OpenAI Is Buying the Enterprise Market at Up to 90% Off, and Anthropic Is Bleeding Share

The enterprise AI market has entered its discount-war phase, per The Information’s October reporting via The Decoder: OpenAI is offering discounts of up to 90% to poach Anthropic’s largest customers. The named examples are concrete. A US bank with over $7 billion in assets had its ChatGPT seats doubled to 500 employees at no extra charge, paying under $7 per user against the usual $20 or more. Replit moved most of its AI spend to OpenAI after a discount of more than 30% on a contract worth over $100 million a year, the same shift Replit’s CEO had telegraphed when cost complaints surfaced last week. DataCut’s chief executive said OpenAI’s pricing cut his costs by 80 to 90%.

The Rippling numbers are the ones to memorize

The single most revealing data point comes from Rippling CEO Parker Conrad: OpenAI’s share of his company’s coding workload jumped from 16% to 52%, while Anthropic’s fell from 57% to 18%, a swap driven substantially by price. That is not a trial; that is production workload migration at a company with every incentive to keep the best model, and it says the quality gap has closed enough for money to decide. OpenAI is partly buying market share at the expense of its own margins, but The Decoder’s reporting notes the discounting rests on real cost reductions: the Sol and Luna model lines cut inference costs through more efficient models and infrastructure, which is what makes 90%-off sustainable in a way last year’s discounting was not. The competitive floor is also rising from below, with cheaper Chinese models like DeepSeek and Kimi squeezing both American labs’ list prices; Moonshot’s K3.1 Pro release landed the same week.

What this does to Anthropic’s IPO math

The timing collides with Anthropic’s listing: Q3 revenue hit $16.8 billion with growth decelerating from Q2’s pace, per the investor memo The Decoder cites, ahead of a planned November IPO that investors have already repriced from $2 trillion toward $1.5 trillion on deceleration fears. A competitor systematically buying your largest customers at negative margins is the strongest possible argument for the deceleration case, and Anthropic’s response so far has been to end its own discount program, effectively conceding the price war while defending margin. The strategic bet is that coding and agent workloads stay quality-elastic: that teams like Rippling will return to the best model once the discount expires. OpenAI’s bet is that they will not, that Sol-and-Luna-class quality at a third of the price is the new definition of best.

What to watch

Three signals will show who is winning. First, whether the discounted contracts renew at full price: the bank’s 500 free seats and Replit’s 30% are teaser economics, and the first batch of renewals in 2027 is the real referendum. Second, Anthropic’s Q4 revenue quality: watch whether the deceleration steepens (price-driven churn) or flattens (quality-locked retention), because the IPO prospectus will have to disclose it either way. Third, whether the discounting reaches the usage-based API market or stays in seats-and-contracts, since per-token prices are where Chinese competition bites hardest and where OpenAI’s infrastructure cost cuts matter most. The enterprise AI market spent 2025 proving customers would pay almost anything; October 2025 is when it started proving they wouldn’t.
