OpenAI has crossed $25 billion in annualized revenue and is reportedly taking early steps toward a public listing — potentially before the end of 2026.

Anthropic is not far behind, approaching $19 billion in annualized revenue. Both numbers represent growth that would have seemed implausible two years ago.

For context: OpenAI’s revenue in 2023 was around $1.6 billion. The AI model market has compressed a decade of typical SaaS scaling into about 24 months. That’s not organic enterprise adoption — it’s a platform shift, and the numbers are reflecting that.

OpenAI has passed $25 billion in annualized revenue and is reportedly taking early steps toward a public listing, potentially as soon as late 2026. The company is currently valued at $852 billion — not a typo. Rival Anthropic is approaching $19 billion in annualized revenue.

An OpenAI IPO would be unlike anything the public markets have processed in years. The valuation, the opacity of the business model, the nonprofit-to-capped-profit structure, and the political entanglement — Greg Brockman and other executives have donated heavily to Trump-aligned super PACs — all make this a strange animal for traditional equity analysis.

Reports say SpaceX is quietly positioning for what could be the largest IPO ever. No timeline confirmed. But the groundwork is being laid.

SpaceX is profitable. Has government contracts. Dominates commercial launch. Has Starlink. And has never needed public capital — which means when it does list, it’s doing so from a position of strength rather than necessity.

The valuation conversation when this actually happens is going to be something.
