OpenRouter: the share of business spending between OpenAI and Anthropic models was roughly even in September, vs. Anthropic commanding a 75% share in January (Angel Au-Yeung/Wall Street Journal)

OpenRouter data suggests enterprise spending on OpenAI and Anthropic models has shifted from a strong Anthropic lead to near parity in just a few months, signaling a fast-moving and highly competitive market for AI workloads. For CIOs and IT leaders, this means model selection is becoming a strategic procurement decision rather than a long-term single-vendor bet, with room to optimize for cost, performance, safety, and workload fit as vendors compete for durable enterprise revenue ahead of IPOs. IT organizations should expect continued pricing and product churn, and build governance that supports multi-model adoption and rapid vendor switching.
