Fact orig-057
Rounds as announced or reported, in order: (1) $1.5 million pre-seed from Riot Ventures, announced late 2023 (company homepage, April 2024; orig-050). (2) $19 million seed led by Riot Ventures with AlleyCorp, Initialized Capital, Day One Ventures and Steel Atlas, February 2025 (TechCrunch; Initialized's own post says $18 million; orig-020). (3) $130 million Series A, November 2025, led by Snowpoint, Day One and Dream per ANS (orig-049). (4) March 2026: $450 million, of which $340 million equity and $110 million debt, at a $2 billion valuation, per a Bloomberg report cited by TechCrunch (Bloomberg not read). (5) August 2026: $1 billion Series B led by Sequoia plus a $200 million credit facility led by Erebor Bank and J.P. Morgan (company post; orig-014). TechCrunch says the company did not disclose a valuation and that Bloomberg put it at $6 billion; its July report says part of the new capital had been raised earlier at the lower valuation, so the amounts should not simply be added. Also on record: a growth capital loan and warrants from TriplePoint Venture Growth as of December 31, 2025 (orig-037) and about $8.1 million sold through nine investment pools (orig-056). No financial statements are public; the only federal award is $0 (orig-055); Utah approved up to $106.7 million in post-performance tax credits in July 2026 (csite-024).
