Quick answer
May 2026 AI valuations: Nvidia $5 trillion (more than Apple). OpenAI $500B (private). Anthropic $200B (private). Microsoft AI revenue run-rate $30B/year. Investors are pouring money in because AI tooling is becoming the new "tech stack" — every company eventually needs it. The risk: valuations price in massive future growth that may not materialise on schedule.
The AI boom is the biggest tech wealth creation event since the smartphone era. Some of the valuations are eye-watering. Here is how investors are thinking about them.
The current valuation snapshot
- Nvidia — $5T (largest company in the world)
- OpenAI — $500B private (only Stripe and ByteDance close it)
- Anthropic — $200B private
- xAI (Elon) — $80B private
- Mistral — $30B private
- Hugging Face — $5B private
- AI software companies (CrowdStrike, Palantir, etc.) — combined $1T+
The bull case for these valuations
Bulls argue AI is comparable to the early internet or smartphone era. If AI eventually represents 5-10% of all economic activity, current "AI infrastructure" companies are still cheap. Microsoft, Google, Amazon all betting tens of billions per quarter that AI is permanent infrastructure.
The bear case
Bears point to: Nvidia depending on capex from a handful of customers (Microsoft, Meta, Google); OpenAI losing billions on inference even at $500B valuation; AI capability gains slowing (no GPT-5 → GPT-6 leap predicted in 2026); open source eating margins (DeepSeek). If any of these break, the valuations correct hard.
Historical reference: Cisco hit $500B in 2000 building internet infrastructure. It was correct that the internet was huge. It was wrong that Cisco specifically would capture all the value. Some current AI valuations may follow the same pattern.
What investors are betting on
Nvidia bet: AI compute demand stays exponential. OpenAI bet: ChatGPT becomes everyone's default AI; API revenue scales. Anthropic bet: Enterprise prefers safety-focused Claude; B2B revenue dominates. All three bets could be partially right and still leave room for the others to grow.

Bottom line
AI valuations are eye-watering but defensible IF AI continues to grow. The risk is concentration — a handful of customers and a handful of models drive most value. Watch quarterly capex reports from Microsoft and Google for the real signal.
