Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	Note 24. Commitments and contingencies Commitments As of September 30, 2026 and June 30, 2026, the Group had commitments of $18,947 million and $13,810 million, respectively. These commitments include committed capital expenditure on AI hardware and infrastructure related to site development and construction. Certain of the Group’s purchase commitments provide cancellation flexibility, subject to contractual terms that may include cancellation charges or reimbursement of supplier costs. Cancellation rights vary by supplier, agreement and stage of order fulfilment. Legal and regulatory matters The Group is subject at times to various claims, lawsuits and governmental proceedings relating to the Group’s business and transactions arising in the ordinary course of business. The Group cannot predict the final outcome of such proceedings. Where appropriate, the Group vigorously defends such claims, lawsuits and proceedings. Some of these claims, lawsuits and proceedings seek damages, including, consequential, exemplary or punitive damages, in amounts that could, if awarded, be significant. Certain of the claims, lawsuits and proceedings arising in the ordinary course of business are covered by the Group’s insurance program. The Group maintains property and various types of liability insurance in an effort to protect the Group from such claims. In terms of any matters where there is no insurance coverage available to the Group, or where coverage is available and the Group maintains a retention or deductible associated with such insurance, the Group may establish an accrual for such loss, retention or deductible based on currently available information. In accordance with accounting guidance, if it is probable that a liability has been incurred as of the date of the financial statements, and the amount of loss is reasonably estimable, then an accrual for the cost to resolve or settle these claims is recorded by the Group in the accompanying Condensed Consolidated Balance Sheets. Expenses related to the defense of such claims are recorded by the Group as incurred and included in the accompanying Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). Management, with the assistance of outside counsel, may from time to time adjust such accruals according to new developments in the matter, court rulings, or changes in the strategy affecting the Group’s defense of such matters. On the basis of current information, the Group does not believe there is a reasonable possibility that any material loss will result from any claims, lawsuits and proceedings to which the Group is subject either individually or in the aggregate. Contingencies U.S. importation tariff In April 2025, the Group received a Notice of Action (“NOA”) from U.S. Customs and Border Protection (“CBP”) challenging the country of origin of mining hardware imported by the Group to the U.S. between April 2024 and February 2025. The NOA asserted that the country of origin of the mining hardware is China and notified the Group of an assessment of a U.S. importation tariff of 25%. The seller has represented to the Group that the country of origin of the mining hardware was not China. Certificates of origin and/or commercial invoices and shipping documents for all mining hardware shipments assessed in the NOA have been provided to the Group to support this claim. The Group had contested the NOA and the associated tariff cost of approximately $100 million. No loss contingency had been recognized in respect of this assessment. In October 2026, CBP approved the Group’s protests and accepted the declared country of origin of the mining hardware covered by those protests. Accordingly, no additional tariff, administrative fee or interest is payable in respect of the above matter. Non-Refundable Sales Tax The Canada Revenue Agency (“CRA”) asserts that 5% Goods and Services Tax (“GST”) should be applied to services exported to the Australian parent under an intercompany services agreement. The CRA’s position is based on its determination that the Australian parent has a permanent establishment in Canada, thereby requiring the Canadian subsidiaries to charge and remit GST on those services. On March 31, 2025, the Group received a Notice of Confirmation from the CRA upholding this assessment. In response, the Group filed a Notice of Appeal with the Tax Court of Canada to dispute the assessment. As of September 30, 2026, the total amount of GST under dispute related to the services supplied to the Australian parent entity is approximately $28 million. Based on the current status of the dispute and the strength of the Group’s legal position, the Group has concluded that it is reasonably possible, but not probable, that an outflow of economic resources will be required as of September 30, 2026. Accordingly, the Group has not recorded a loss contingency as of September 30, 2026, in respect of this matter.
