Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Business	Organization and Business Sphere 3D Corp. was incorporated under the Business Corporations Act (Ontario) on May 2, 2007 as T.B. Mining Ventures Inc. On March 24, 2015, the Company completed a short-form amalgamation with a wholly-owned subsidiary. In connection with the short-form amalgamation, the Company changed its name to “Sphere 3D Corp.” Any reference to the “Company”, “Sphere 3D”, “we”, “our”, “us”, or similar terms refers to Sphere 3D Corp. and its subsidiaries. In January 2022, the Company commenced operations of its Bitcoin mining business. On June 1, 2026, the Company consummated the Combination (as defined below). Following the Combination, the Company is dedicated to becoming a leader as a digital infrastructure company focused on operating and expanding scalable power and data center assets for high-performance computing, artificial intelligence (“AI”) workloads, and digital asset infrastructure. Business Combination On March 5, 2026, the Company and Cathedra Bitcoin Inc. (“Cathedra”), entered into a definitive agreement to combine the two companies in an all-stock transaction (the “Arrangement Agreement”). On June 1, 2026, the business combination was effected by way of a plan of arrangement under the Business Corporations Act (British Columbia), pursuant to which S3D Acquisition Corp., the Company’s wholly-owned subsidiary, acquired all of the issued and outstanding shares of Cathedra in a share-for-share transaction, and Cathedra became a wholly-owned subsidiary of the Company (the “Combination”). As a result of the Combination, the Company has expanded beyond proprietary Bitcoin mining into a vertically integrated data center infrastructure platform, combining our mining fleet and capital markets access with Cathedra’s energy and power infrastructure assets and data center development capabilities. Share Consolidation On February 9, 2026, the Company filed an Articles of Amendment to effect a share consolidation (also known as a reverse stock split) of its issued and outstanding common shares in the ratio of 1-for-10. The share consolidation was effective on February 9, 2026. The Company’s common shares began trading on an adjusted basis on the Nasdaq Capital Market (“Nasdaq”) at the opening of trading on February 10, 2026. All share and per share amounts have been restated for all periods presented to reflect the share consolidation.
Substantial Doubt about Going Concern	Going Concern Management has projected that based on our recurring losses, negative cash flows from operating activities, and our hashing rate at June 30, 2026, cash on hand may not be sufficient to allow the Company to continue operations and there is substantial doubt about our ability to continue as a going concern within 12 months from the date of issuance of our financial statements if we are unable to raise additional funding for operations. We expect our working capital needs to increase in the future as we continue to expand and enhance our operations. Our ability to raise additional funds for working capital through equity or debt financings or other sources may depend on the financial success of our business and successful implementation of our key strategic initiatives, financial, economic and market conditions and other factors, some of which are beyond our control. We require additional capital and if we are unsuccessful in raising that capital at a reasonable cost and at the required times, or at all, we may not be able to continue our business operations in the cryptocurrency mining industry or we may be unable to advance our growth initiatives, either of which could adversely impact our business, financial condition and results of operations. To mitigate these risks we are taking steps to reduce our cost of mining, have refreshed our mining fleet to improve our mining efficiency, and expect that recently contracted hosting agreements should further support these efforts. Significant changes from our current forecasts, including but not limited to: (i) shortfalls from projected earnings; (ii) increases in operating costs; (iii) decreases in the value of cryptocurrency; and (iv) if we do not maintain compliance with the requirements of Nasdaq and/or we do not maintain our listing with Nasdaq, it could have a material adverse impact on our ability to access the level of funding necessary to continue operations at current levels. These factors, among others, should they occur may result in our inability to continue as a going concern within 12 months from the date of issuance of our financial statements. The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business and do not include any adjustments that might result from the outcome of this uncertainty.
