Fact fund-008
Adding every headline number gives about $1.81 billion: $1.5M pre-seed, about $19M seed, $130M Series A, $450M in March 2026 ($340M equity, $110M debt), the $1B Series B and a $200M credit facility, plus $5M of TriplePoint loans (fund-002 to fund-009). That sum double-counts. TechCrunch's sources said part of the $1 billion had been raised earlier at the lower valuation (fund-006, fund-007), and the Series B post does not say whether the March equity is inside the $1 billion; the credit facility's relation to the March debt is not stated either. The research firm Sacra's share-class table points the same way: it lists Series B-2 and B-3 preferred shares issued in March 2026 and Series B-1 and B-4 in August 2026 (fund-023), which would put the March equity inside the Series B; its source documents sit behind a login and were not read. Equity alone is therefore between about $1.15 billion (if the March $340M is part of the $1B, as the reporting and Sacra's table suggest) and about $1.49 billion (if it is separate). Sacra's page text, which describes rounds only through March 2026, puts 'total reported lifetime funding' at about $600.5 million, matching $150.5M plus $450M, while the same page's header shows $580 million; the last total the company announced, as reported, was 'more than $150 million' (November 2025, fund-004). Borrowed money is a promise to repay, not ownership, and a credit facility is a ceiling that may not have been drawn. Valar files no Form D (fund-010) and publishes no accounts, so no public record gives an authoritative total as of 29 Sept 2026. Confidence is 'reported' because the March figures rest on one Bloomberg report.
