xAI — Total Funding Raised: $12 billion

Note: The source URL returns a 404 error with no actual article content. While the URL title suggests it discusses xAI's $6B funding round (which would be relevant to the claim about $12B total across Series A and B), the actual page content is inaccessible. Without access to the source material, the claim cannot be verified, contradicted, or confirmed. The claim mentions approximately $12B across Series A and Series B rounds, and the URL suggests a $6B round in December 2024, which could be consistent with the claim if there was an earlier Series A round of ~$6B, but this cannot be verified from the unavailable source.
