Accounting Policies [Abstract] |
Custody and Fair Valuation of Platinum | 2.1 Custody and Fair Valuation of Platinum The Trust follows the provisions of ASC 820, Fair Value Measurements (“ASC 820”). ASC 820 provides guidance for determining fair value and requires increased disclosure regarding the inputs to valuation techniques used to measure fair value. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Platinum is held by ICBC Standard Bank Plc (the “Custodian”), on behalf of the Trust, at the Custodian’s London, United Kingdom vaulting premises. 99.81% and 99.84% of platinum is in the form of good delivery platinum bars as of June 30, 2025 and 2024, respectively. A current list of all platinum held by the Custodian is available on the sponsor’s website. The cost of platinum is determined according to the average cost method and the fair value is based on the London Bullion Market Association (“LBMA”) Platinum Price PM. LBMA Platinum Price PM is the price per troy ounce of platinum, stated in U.S. dollars, determined by the LME, following an auction process starting after 2:00 p.m. (London time), on each day that the London platinum market is open for business, and announced by the LME shortly thereafter. The per Share amount of platinum exchanged for a purchase or redemption is calculated daily by the Trustee, using the LBMA Platinum Price PM to calculate the platinum amount in respect of any liabilities for which covering platinum sales have not yet been made, and represents the per Share amount of platinum held by the Trust, after giving effect to its liabilities, to cover expenses and liabilities and any losses that may have occurred. ASC 820 establishes a hierarchy that prioritizes inputs to valuation techniques used to measure fair value. The three levels of inputs are as follows: Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities that the Trust has the ability to access. Level 2: Observable inputs other than quoted prices included in level 1 that are observable for the asset or liability either directly or indirectly. These inputs may include quoted prices for the identical instrument on an inactive market, prices for similar instruments and similar data. Level 3: Unobservable inputs for the asset or liability to the extent that relevant observable inputs are not available, representing the Trust’s own assumptions about the assumptions that a market participant would use in valuing the asset or liability, and that would be based on the best information available. The following table summarizes the Trust’s investments at fair value: Schedule of Trust Investments Fair Value

Expenses, realized gains and losses | 2.2 Expenses, realized gains and losses The Trust’s only ordinary recurring fee is expected to be the fee paid to the Sponsor, which will accrue daily at an annualized rate equal to 0.50% of the adjusted daily net asset value of the Trust, paid monthly in arrears. The Sponsor has agreed to assume administrative and marketing expenses incurred by the Trust, including the Trustee’s monthly fee and out of pocket expenses, the Custodian’s fee and the reimbursement of the Custodian’s expenses, exchange listing fees, United States Securities and Exchange Commission (the “SEC”) registration fees, printing and mailing costs, audit fees and certain legal expenses. The fees payable to the Sponsor were $29,422 as of June 30, 2025 and $17,280 as of June 30, 2024. The Sponsor’s Fee was $242,983 for the year ended June 30, 2025, or 0.50% of the Trust’s assets on an annualized basis, $187,695 for the year ended June 30, 2024, or 0.50% of the Trust’s assets on an annualized basis, and $216,715 for the year ended June 30, 2023, or 0.50% of the Trust’s assets on an annualized basis. With respect to expenses not otherwise assumed by the Sponsor, the Trustee will, at the direction of the Sponsor or in its own discretion, sell the Trust’s platinum as necessary to pay these expenses. When selling platinum to pay expenses, the Trustee will endeavor to sell the smallest amounts of platinum needed to pay these expenses in order to minimize the Trust’s holdings of assets other than platinum. Other than the Sponsor’s Fee, the Trust had no expenses during the years ended June 30, 2025, 2024 and 2023. Unless otherwise directed by the Sponsor, when selling platinum the Trustee will endeavor to sell at the price established by the LBMA PM Platinum Price. The Trustee will place orders with dealers (which may include the Custodian) through which the Trustee expects to receive the most favorable price and execution of orders. The Custodian may be the purchaser of such platinum only if the sale transaction is made at the next LBMA PM Platinum Price or such other publicly available price that the Sponsor deems fair, in each case as set following the sale order. A gain or loss is recognized based on the difference between the selling price and the cost of the platinum sold. Neither the Trustee nor the Sponsor is liable for depreciation or loss incurred by reason of any sale. Realized gains and losses result from the transfer of platinum for Share redemptions and / or to pay expenses and are recognized on a trade date basis as the difference between the fair value and cost of platinum transferred. Gain or loss on sales of platinum bullion is calculated on a trade date basis using the average cost method.
Platinum. Receivable and Payable | 2.3. Platinum. Receivable and Payable Platinum receivable or payable represents the quantity of platinum covered by contractually binding orders for the creation or redemption of Shares respectively, where the platinum has not yet been transferred to or from the Trust’s account. Generally, ownership of the platinum is transferred within two business days of the trade date.
Creations and Redemptions of Shares | 2.4. Creations and Redemptions of Shares The Trust issues and redeems in one or more blocks of 50,000 Shares (a block of 50,000 Shares is called a “Basket”) only to Authorized Participants on an ongoing basis. The creation and redemption of Baskets will only be made in exchange for the delivery to the Trust or the distribution by the Trust of the amount of platinum represented by the Baskets being created or redeemed, the amount of which will be based on the combined ounces represented by the number of shares included in the Baskets being created or redeemed determined on the day the order to create or redeem Baskets is properly received. Orders to create and redeem Baskets may be placed only by Authorized Participants. An Authorized Participant must: (1) be a registered broker-dealer or other securities market participant, such as a bank or other financial institution, which, but for an exclusion from registration, would be required to register as a broker-dealer to engage in securities transactions, (2) be a participant in DTC, and (3) must have an agreement with the Custodian establishing an unallocated account in London or have an existing unallocated account meeting the standards described herein. To become an Authorized Participant, a person must enter into an Authorized Participant Agreement with the Sponsor and the Trustee. The Authorized Participant Agreement provides the procedures for the creation and redemption of Baskets and for the delivery of the platinum required for such creations and redemptions. The Authorized Participant Agreement and the related procedures attached thereto may be amended by the Trustee and the Sponsor, without the consent of any investor or Authorized Participant. A transaction fee of $500 will be assessed on all creation and redemption transactions. Multiple Baskets may be created on the same day, provided each Basket meets the requirements described below and that the Custodian is able to allocate platinum to the Trust Allocated Account such that the Trust Unallocated Account holds no more than 192 ounces of platinum at the close of a business day. Authorized Participants who make deposits with the Trust in exchange for Baskets will receive no fees, commissions or other form of compensation or inducement of any kind from either the Sponsor or the Trust, and no such person has any obligation or responsibility to the Sponsor or the Trust to effect any sale or resale of shares.
Income Taxes | 2.5. Income Taxes The Trust is classified as a “grantor trust” for United States federal income tax purposes. As a result, the Trust itself will not be subject to United States federal income tax. Instead, the Trust’s income and expenses will “flow through” to the Shareholders, and the Trustee will report the Trust’s proceeds, income, gains, losses and deductions to the Internal Revenue Service on that basis. The Sponsor has evaluated whether or not there are uncertain tax positions that require financial statement recognition and has determined that no reserves for uncertain tax positions are required as of June 30, 2025 and June 30, 2024. The Sponsor evaluates tax positions taken or expected to be taken in the course of preparing the Trust’s tax returns to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions not deemed to meet that threshold would be recorded as an expense in the current year. The Trust is required to analyze all open tax years. Open tax years are those years that are open for examination by the relevant income taxing authority. As of June 30, 2025, the 2025, 2024, 2023 and 2022 tax years remain open for examination.
Recently Issued Accounting Pronouncement | 2.6 Recently Issued Accounting Pronouncement The Trust adopted FASB Accounting Standards Update 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures (“ASU 2023-07”). The Trust operates in one segment. The segment derives its revenues from Trust investments made in accordance with the defined investment strategy of the Trust, as prescribed in the Trust’s prospectus. The Chief Operating Decision Maker (“CODM”) is the Sponsor. The CODM monitors the operating results of the Trust. The financial information the CODM leverages to assess the segment’s performance and to make decisions for the Trust’s single segment, is consistent with that presented within the Trust’s financial statements.
