Madrona’s IA40 showing 45 private AI companies with $410B raised—and 92% of that concentrated in Anthropic, OpenAI, and Databricks—confirms a barbell market: a few capital magnets and a long tail.

If you’re building on open models, assume your cost and latency advantage will be competed away—start benchmarking against specialized optimizers now.
