ZeroStack, a crypto firm whose treasury is dominated by the AI token 0G, reported a steep decline in the fair‑value of its digital assets, dropping from $163.3 million to $15.17 million as of June 30, and said it will rely on staking rewards to sustain operations. The company disclosed in its July 31 Form 10‑Q for the quarter ended June 30 that cash on hand was $2.6 million, working capital was negative $600,000, and it posted a $61.3 million net loss for the first half of 2026, with an $82.5 million unrealized loss from remeasuring its digital assets. ZeroStack held 75.1 million 0G tokens with a recorded cost of $163.33 million but a fair value of $15.17 million; including a small Bitcoin position, total digital assets were valued at $15.21 million. The firm recognized $3.78 million in revenue from staking 6.62 million 0G tokens, of which $2.4 million in proceeds were realized from sales of 4.94 million tokens, while cash used for operations totaled $2.47 million. Management said it may monetize staking rewards and, if needed, sell underlying token holdings, but noted that reward rates could fall and sales depend on market conditions, leaving uncertainty about cash availability for the coming year. The filing indicates substantial going‑concern doubt but does not constitute a formal insolvency declaration.
