Organization, Consolidation and Presentation of Financial Statements [Abstract]
Future operations and going concern	Note 2. Future operations and going concern The Group recorded a loss from operations in this reporting period and the accompanying consolidated financial statements have been prepared assuming that the Group will continue as a going concern. The Group incurred a net operating loss of USD 4.1 million in the year 2023 and had positive working capital of USD 9.8 million as at December 31, 2023, calculated as the difference between current assets and current liabilities. Based on the Group’s cash projections up to March 31, 2025, SEALSQ has sufficient liquidity to fund operations. We note that, historically, the Group has been dependent on financing from its parent, WISeKey International Holding Ltd or other investors, to augment the operating cash flow to cover its cash requirements. Based on the foregoing, Management believe it is correct to present these figures on a going concern basis.

The entire disclosure when substantial doubt is raised about the ability to continue as a going concern. Includes, but is not limited to, principal conditions or events that raised substantial doubt about the ability to continue as a going concern, management's evaluation of the significance of those conditions or events in relation to the ability to meet its obligations, and management's plans that alleviated or are intended to mitigate the conditions or events that raise substantial doubt about the ability to continue as a going concern.
