xAI — Total Funding Raised: $26.0 billion

Note: The source text confirms that xAI raised $20B in Series E as of January 2026, but it does not explicitly state the total cumulative funding across all rounds. The claim references 'Over $26B total raised across all rounds,' but this specific statement does not appear in the provided source text excerpt. While the $20B Series E round is confirmed, the total funding figure of $26B+ cannot be verified from the source text provided. To confirm the claim, the source would need to explicitly state total cumulative funding across all rounds.
