Valar Atomics pro rata feud

Business · Heat 1.2 / 10 · 2 shows · 12m airtime

On October 9, 2026, Valar Atomics founder Isaiah Taylor posted that all investors except Day One Ventures agreed to waive pro rata rights. Valar has since sued Day One over an amendment removing spring-back rights made the day before its $1 billion Series B closed. Day One has retained a law firm and is fighting the suit. The terms of the litigation remain unstated, and it is not yet established which side the amendment favored or how the other investors' waivers bear on the case.
