Subsequent Events [Abstract]
Subsequent events	Note 30. Subsequent events The Group has completed an evaluation of all subsequent events after the balance sheet date up to the date that the Consolidated Financial Statements are issued. Except as described above and below, the Group has concluded no other subsequent events have occurred that require disclosure. Subsequent Equity Awards On July 1, 2026, following Board approval on June 30, 2026, the Company granted an award of 9,099,328 restricted share units to each of its Co-Chief Executive Officers under the Company’s 2025 Omnibus Plan. The awards will vest in equal annual installments over the four-year period following the grant date, subject to continued service through the applicable vesting date. In addition, following the applicable vesting date, each tranche of RSUs will be subject to an additional two-year post-vesting holding period requirement during which the Co-CEOs generally may not sell, transfer, or otherwise monetize the vested RSUs. The aggregate grant-date fair value of the awards will be recognized as share-based compensation expense over the four-year requisite service period. No related expense was recognized during the year ended June 30, 2026. Business combinations On May 4, 2026, the Company entered into a merger agreement to acquire 100% of Mirantis, Inc. (“Mirantis”), a U.S.-based cloud software and services provider. The acquisition closed on August 3, 2026. Aggregate consideration was approximately $544 million, payable through the issuance of 12.6 million Ordinary shares plus cash and restricted stock units of approximately $40 million as of closing. Because the acquisition closed after June 30, 2026, it is a non-recognized subsequent event; accordingly, no assets acquired or liabilities assumed have been recognized in these consolidated financial statements. The initial accounting for the business combination, including the allocation of consideration to the identifiable assets acquired and liabilities assumed and the measurement of goodwill and acquired intangible assets, is incomplete as of the date these financial statements were issued. The Group expects to provide the required acquisition-related disclosures in a subsequent filing once the initial accounting has been completed. August 2026 Financing Agreement On August 25, 2026, IE Mackenzie Compute Ltd. (the “Borrower”), a British Columbia corporation and wholly owned subsidiary of IREN Limited, entered into certain financing agreements (collectively, the “August 2026 Financing Agreements”) for aggregate financing of up to $2.4 billion, comprised of (i) an approximately $1.2 billion master financing and security agreement (the “MFSA”) and (ii) an approximately $1.2 billion aggregate principal amount of the Borrower’s Notes (the “Notes”) pursuant to a note purchase agreement. The August 2026 Financing Agreements finance GPU servers and ancillary equipment owned by the Borrower and located at the Mackenzie data center facilities in British Columbia, Canada, which the Borrower expects to take delivery of in stages through to December 31, 2026. Borrowings under the MFSA and issuances of Notes will be made in stages and mature 30 months after the relevant funding date. Borrowings under the MFSA and the Notes bear interest at a fixed rate of 9.0% per annum, and principal amounts outstanding amortize in accordance with applicable amortization schedules.

The Group has completed an evaluation of all subsequent events after the balance sheet date up to the date that the Consolidated Financial Statements are issued. Except as described above and below, the Group has concluded no other subsequent events have occurred that require disclosure.

On July 1, 2026, following Board approval on June 30, 2026, the Company granted an award of 9,099,328 restricted share units to each of its Co-Chief Executive Officers under the Company’s 2025 Omnibus Plan.

In addition, following the applicable vesting date, each tranche of RSUs will be subject to an additional two-year post-vesting holding period requirement during which the Co-CEOs generally may not sell, transfer, or otherwise monetize the vested RSUs.

The aggregate grant-date fair value of the awards will be recognized as share-based compensation expense over the four-year requisite service period. No related expense was recognized during the year ended June 30, 2026.
