Who they are
xAI is a frontier lab based in the United States, documented at x.ai. Current models are API-served; older Grok weights have been released under Apache-2.0.
How they are funded
Subsidiary of a listed parent. No longer independent. Merged with X Corp in 2025, then acquired by SpaceX in an all-stock deal announced February 2026 that valued xAI at $250bn; SpaceX itself listed on Nasdaq (SPCX) in June 2026, so xAI is now a division of a public company. The Gulf sovereign capital from its earlier rounds did not go away — in an all-stock deal it converted into equity of the listed parent, which is why those funders are still listed below.
| SpaceX (Nasdaq: SPCX) | United States |
| Kingdom Holding | Saudi Arabia |
| Qatar Investment Authority | Qatar |
| Valor Equity Partners | United States |
| Sequoia Capital | United States |
| Andreessen Horowitz | United States |
Unverified. Ownership and funding are compiled from public reporting as of 2026-08. Unlike the hashes and signatures in this registry, Sovereign Frontier cannot attest any of it, and private-company funding changes faster than this page does. Treat it as a starting point for your own due diligence, not as evidence.
