Class of Stock Disclosures [Abstract]
Preferred Stock	Preferred Shares Series H Preferred Shares On October 1, 2021, the Company filed articles of amendment to create a series of preferred shares, being, an unlimited number of Series H Preferred Shares and to provide for the rights, privileges, restrictions and conditions attaching thereto. The Series H Preferred Shares are convertible provided (and only if and to the extent) that prior shareholder approval of the issuance of all Sphere 3D common shares issuable upon conversion of the Series H Preferred Shares has been obtained in accordance with the rules of the Nasdaq Stock Market, at any time from time to time, at the option of the holder thereof, into 142.857 Sphere 3D common shares for every Series H Preferred Share. Each holder of the Series H Preferred Shares, may, subject to prior shareholder approval, convert all or any part of the Series H Preferred Shares provided that after such conversion the common shares issuable, together with all the common shares held by the shareholder in the aggregate would not exceed 9.99% of the total number of outstanding common shares of the Company. Each Series H Preferred Share has a stated value of $1,000. The Series H Preferred Shares are non-voting and do not accrue dividends. These features include, in the event of the liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, deemed liquidation or any other distribution of the assets of the Company among its shareholders for the purpose of winding-up its affairs, the Series H Preferred Shares shall entitle each of the holders thereof to receive an amount equal to the Series H subscription price per Series H Preferred Share, as defined in the agreement, to be paid before any amount is paid or any assets of the Company are distributed to the holders of its common shares. In November 2022, the Company entered into the Modified Hertford Agreement. The Modified Hertford Agreement provides for certain resale restrictions applicable to the common shares that are issuable upon the conversion of the remaining Series H Preferred Shares during the two-year period ending on December 31, 2024, which are different from the restrictions contained in the Hertford Agreement. Commencing January 1, 2024 and terminating on December 31, 2024, holders of Series H Preferred Shares are permitted to (a) convert Series H Preferred Shares in an aggregate amount up to or equal to 10.0% of the aggregate number of Series H Preferred Shares outstanding on the first day of each such month and (b) sell the resulting number (and no greater number) of such converted common shares within such month. In August 2023, the Company entered into an Amended and Restated Agreement (the “Hertford Amendment”) with Hertford Advisors Ltd. and certain other parties listed in the Hertford Amendment (together, the “Hertford Group”), which amends and restates in its entirety the purchase agreement between the Company and Hertford Advisors Ltd. dated July 31, 2021, as modified by the amendment to such agreement dated November 7, 2022 (together, the “Original Hertford Agreement”). As an inducement to enter into the Hertford Amendment, the Company issued to Hertford 1,376 Series H Preferred Shares and 800,000 warrants with an aggregate fair value of $1.0 million. Pursuant to the Hertford Amendment, Hertford exchanged 14,980 Series H Preferred Shares for Series H Preferred Shares held by other persons (the “Exchanged Series H Preferred Shares”). The Hertford Group shall not be permitted to sell more than that number of common shares equal to 20% of the previous trading day's volume for common shares traded on the principal exchange upon which the common shares are listed and, for any subsequent trading day, the shares sold by the Hertford Group on the previous trading day shall be excluded when calculating the day's volume. Beginning on January 1, 2025, the Hertford Group shall not be prohibited, restrained or otherwise limited from converting its Series H Preferred Shares or selling any common shares converted from Series H Preferred Shares, subject to applicable laws, exchange requirements and the terms and conditions of the Series H Preferred Shares. In August 2023, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) pursuant to which the Company issued to two investors a total of 13,764 of the Company’s Series H Preferred Shares and a total of 1,966,293 common share purchase warrants (the “Warrants”), each of which entitled the holder to purchase one common share of the Company (the “Warrant Shares”). Pursuant to the terms of the Purchase Agreement, the Company received gross proceeds of $3.0 million. The Company issued a total of 1,377 Series H Preferred Shares and 196,629 warrants as a finder’s fee for the transaction with an aggregate fair value of $0.5 million. Pursuant to the terms of the Purchase Agreement, the Company will reserve for issuance the maximum aggregate number of common shares that are issuable upon exercise in full of the Warrants at any time. The Warrants issued in connection with the Hertford Amendment and the Purchase Agreement are exercisable beginning February 12, 2024 and February 23, 2024, respectively, at an initial exercise price of $2.75 per share and have a term of three years from the date of issuance. The exercise price of the Warrants are subject to adjustment for certain stock splits, stock combinations and dilutive share issuances. In accordance with the authoritative guidance for distinguishing liabilities from equity, the Company has determined that its Series H preferred shares carry certain redemption features beyond the control of the Company. Accordingly, the Series H Preferred Shares are presented as temporary equity. For the six months ended June 30, 2024 and 2023, the Company issued 4,043,850 and 1,431,283 common shares for the conversion of 28,307 and 10,019 Series H Preferred Shares, respectively.
