Revenue Recognition and Deferred Revenue [Abstract]
OTHER LONG-TERM DEFERRED INCOME	OTHER LONG-TERM DEFERRED INCOME Cooperative Development Agreement—In December 2023, we entered into the Third Amendment of Cooperative Development Agreement (the "CDA Amendment") with XTO Holdings, LLC ("XTO Holdings") and XTO Delaware Basin LLC, as successors in interest to BOPCO, L.P. ("XTO Delaware Basin," and together with XTO Holdings, "XTO"), with an effective date of January 1, 2024 ("Amendment Date"). The CDA Amendment further amends that certain Cooperative Development Agreement, by and between us, BOPCO, L.P. and the other parties thereto, effective as of February 28, 2011 (as amended, including by the CDA Amendment, the "CDA"), which was executed for the purpose of pursuing the cooperative development of potassium and oil and gas on certain lands. The CDA restricts and limits the rights of Intrepid and XTO, as successors in interest to BOPCO, L.P., to explore and develop their respective interests, including limitations on the locations of wells. Intrepid and XTO entered into the CDA Amendment in an effort to further the cooperation, remove the restrictions and limitations, and allow for the efficient co-development of resources within the Designated Potash Area ("DPA") consistent with the United States Secretary of the Interior Order 3324. Pursuant to the CDA Amendment, among other things, we agreed to provide support to XTO for development and operation of XTO's oil and gas interests within the DPA. As consideration under the CDA Amendment, XTO agreed to pay us an initial fee of $50.0 million (the "Initial Fee"). We received a partial payment of $5.0 million of the Initial Fee in December 2023, and we received payment of the remaining $45.0 million from XTO in January 2024. The CDA Amendment further provides that we shall receive an additional one-time payment equal to $50.0 million (the "Access Fee"), which XTO will pay within 90 days upon the earlier occurrence of (i) the approval of the first new or expanded drilling island within a specific area to be used by XTO or (ii) within seven years of the anniversary of the Amendment Date. XTO is also required to pay additional amounts to Intrepid as an "Access Realization Fee," up to a maximum of $100.0 million, (the "Access Realization Fee") in the event of certain additional drilling activities by XTO. Because the cooperative development support we are providing under the CDA is not an output of our ordinary business activities, ASC Topic 606, Revenue from Contracts with Customers ("ASC 606") does not apply to the CDA. However, we apply the principles in ASC 606 by analogy to determine amounts of other income to recognize. Under ASC 606, we are required to identify the performance obligations in the CDA and to determine the transaction price. The transaction price may include fixed consideration, variable consideration, or both. Variable consideration may only be included in the transaction price if it is probable that a significant reversal of amounts recognized will not occur (referred to as the variable consideration constraint). The Access Realization Fee is considered variable consideration. Our performance obligation under the CDA Amendment is to "stand-ready" to provide support to XTO, when and as needed, during the term of the CDA Amendment. We estimate the transaction price to be $100.0 million, which is comprised of the $50.0 million Initial Fee and the $50.0 million Access Fee. We are not including any amounts of the Access Realization Fee in the transaction price because of the variable consideration constraint. Since our performance obligation is a "stand-ready" obligation, we are recognizing the transaction price on a straight-line basis over the term of the CDA Amendment which ends on February 28, 2046. For both of the three months ended June 30, 2026, and 2025, we recorded other operating income of $1.1 million from the CDA Amendment. For both of the six months ended June 30, 2026, and 2025, we recorded other operating income of $2.3 million from the CDA Amendment. Because we have not yet been paid the Access Fee included in the transaction price, we recorded a long-term receivable for the amount of the Access Fee that we earned through June 30, 2026, of $5.6 million, which is included in "Other assets, net" on the Condensed Consolidated Balance Sheets. For the amount of the Initial Fee we earned during the three and six months ended June 30, 2026, and 2025, we reduced the "Deferred other income, long-term" liability recorded on our Condensed Consolidated Balance Sheets. As of June 30, 2026, we had $2.3 million recorded in "Other current liabilities" and $42.1 million recorded in "Deferred other income, long-term" on the Condensed Consolidated Balance Sheets for the unearned portion of the Initial Fee. As of December 31, 2025, we had $2.3 million recorded in "Other current liabilities" and $43.2 million recorded in "Deferred other income, long-term" on the Condensed Consolidated Balance Sheets.
