Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of the financial statements requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. AB Holding’s financial statements and notes should be read in conjunction with the consolidated financial statements and notes of AB, which are included in this Form 10-K. Investment in AB AB Holding records its investment in AB using the equity method of accounting. AB Holding’s investment is increased to reflect its proportionate share of income of AB and decreased to reflect its proportionate share of losses of AB and cash distributions made by AB to its Unitholders. In addition, AB Holding's investment is adjusted to reflect its proportionate share of certain capital transactions of AB. Cash Distributions AB Holding is required to distribute all of its Available Cash Flow, as defined in the Amended and Restated Agreement of Limited Partnership of AB Holding (“ AB Holding Partnership Agreement ”), to its Unitholders pro rata in accordance with their percentage interests in AB Holding. Available Cash Flow is defined as the cash distributions AB Holding receives from AB minus such amounts as the General Partner determines, in its sole discretion, should be retained by AB Holding for use in its business (such as the payment of taxes) or plus such amounts as the General Partner determines, in its sole discretion, should be released from previously retained cash flow. On February 8, 2023, the General Partner declared a distribution of $0.70 per unit, representing a distribution of Available Cash Flow for the three months ended December 31, 2022. Each general partnership unit in AB Holding is entitled to receive distributions equal to those received by each AB Holding Unit. The distribution is payable on March 16, 2023 to holders of record at the close of business on February 21, 2023. Total cash distributions per Unit paid to Unitholders during 2022, 2021 and 2020 were $3.54, $3.58 and $2.79, respectively. Long-term Incentive Compensation Plans AB maintains several unfunded, non-qualified long-term incentive compensation plans, under which the company grants awards of restricted AB Holding Units to its employees and members of the Board of Directors, who are not employed by AB or by any of AB’s affiliates (“ Eligible Directors ”). AB funds its restricted AB Holding Unit awards either by purchasing AB Holding Units on the open market or purchasing newly-issued AB Holding Units from AB Holding, and then keeping these AB Holding Units in a consolidated rabbi trust until delivering them or retiring them. In accordance with the AB Holding Partnership Agreement, when AB purchases newly-issued AB Holding Units from AB Holding, AB Holding is required to use the proceeds it receives from AB to purchase the equivalent number of newly-issued AB Units, thus increasing its percentage ownership interest in AB. AB Holding Units held in the consolidated rabbi trust are corporate assets in the name of the trust and are available to the general creditors of AB. Repurchases of AB Holding Units for the years ended December 31, 2022 and 2021 consisted of the following: Years Ended December 31 2022 2021 (in millions) Total amount of AB Holding Units Purchased (1) 5.2 5.6 Total Cash Paid for AB Holding Units Purchased (1) $ 211.8 $ 262.3 Open Market Purchases of AB Holding Units Purchased (1) 2.3 2.6 Total Cash Paid for Open Market Purchases of AB Holding Units (1) $ 92.7 $ 117.9 (1) Purchased on a trade-date basis. The difference between open-market purchases and units retained reflects the retention of AB Holding Units from employees to fulfill statutory tax withholding requirements at the time of delivery of long-term incentive compensation awards. Each quarter, AB considers whether to implement a plan to repurchase AB Holding Units pursuant to Rules 10b5-1 and 10b-18 under the Securities Exchange Act of 1934, as amended (“ Exchange Act ”). A plan of this type allows a company to repurchase its shares at times when it otherwise might be prevented from doing so because of self-imposed trading blackout periods or because it possesses material non-public information. Each broker selected by AB has the authority to repurchase AB Holding Units on AB’s behalf in accordance with the terms and limitations specified in the plan. Repurchases are subject to regulations promulgated by the U.S. Securities and Exchange Commission (“ SEC ”) as well as certain price, market volume and timing constraints specified in the plan. We did not adopt a plan during the fourth quarter of 2022. AB may adopt additional plans in the future to engage in open-market purchases of AB Holding Units to help fund anticipated obligations under its incentive compensation award program and for other corporate purposes. During 2022, AB granted to employees and Eligible Directors 4.7 million restricted AB Holding Units (including 3.8 million granted in December for 2022 year-end awards). During 2021, AB granted to employees and Eligible Directors 7.0 million restricted AB Holding Units (including 3.4 million granted in December for 2021 year-end awards). AB used AB Holding Units repurchased during the periods and newly-issued AB Holding Units to fund these awards. During 2022 and 2021, AB Holding issued 5,774 and 0.1 million AB Holding Units, respectively, upon exercise of options to buy AB Holding Units. AB Holding used the proceeds of $0.2 million and $3.4 million, respectively, received from award recipients as payment in cash for the exercise price to purchase the equivalent number of newly-issued AB Units. Subsequent Events We have evaluated subsequent events through the date that these financial statements were filed with the SEC and did not identify any subsequent events that would have required disclosure in these financial statements.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes AB Holding is a publicly-traded partnership (" PTP ") for federal tax purposes and, accordingly, is not subject to federal or state corporate income taxes. However, AB Holding is subject to the 4.0% New York City unincorporated business tax (“ UBT ”), net of credits for UBT paid by AB, and to a 3.5% federal tax on partnership gross income from the active conduct of a trade or business. AB Holding’s partnership gross income is derived from its interest in AB. The principal reasons for the difference between AB Holding’s effective tax rates and the UBT statutory tax rate of 4.0% are as follows: Years Ended December 31 2022 2021 2020 (in thousands) UBT statutory rate $ 12,220 4.0 % $ 16,653 4.0 % $ 12,336 4.0 % Federal tax on partnership gross business income 30,676 10.0 29,643 7.1 28,522 9.2 State income taxes 663 0.2 840 0.2 502 0.2 Credit for UBT paid by AB (12,220) (4.0) (16,653) (4.0) (12,336) (4.0) Income tax expense and effective tax rate $31,339 10.3 % $ 30,483 7.3 % $ 29,024 9.4 % AB Holding’s federal income tax is computed by multiplying certain AB qualifying revenues (primarily U.S. investment advisory fees, research payments and brokerage commissions) by AB Holding’s ownership interest in AB, multiplied by the 3.5% tax rate. AB Holding Units in AB’s consolidated rabbi trust are not considered outstanding for purposes of calculating AB Holding’s ownership interest in AB. Years Ended December 31 % Change 2022 2021 2020 2022-21 2021-20 (in thousands) Net income attributable to AB Unitholders $ 831,813 $ 1,148,623 $ 865,952 (27.6) % 32.6 % Multiplied by: weighted average equity ownership interest 36.7 % 36.2 % 35.6 % Equity in net income attributable to AB Unitholders $ 305,504 $ 416,326 $ 308,404 (26.6) 35.0 AB qualifying revenues $ 2,775,693 $ 2,779,281 $ 2,740,137 (0.1) 1.4 Multiplied by: weighted average equity ownership interest for calculating tax 31.6 % 30.5 % 30.1 % Multiplied by: federal tax 3.5 % 3.5 % 3.5 % Federal income taxes 30,676 29,643 28,522 State income taxes 663 840 502 Total income taxes $ 31,339 $ 30,483 $ 29,024 2.8 5.0 In order to preserve AB Holding’s status as a PTP for federal income tax purposes, management ensures that AB Holding does not directly or indirectly (through AB) enter into a substantial new line of business. If AB Holding were to lose its status as a PTP, it would be subject to corporate income tax, which would reduce materially AB Holding’s net income and its quarterly distributions to AB Holding Unitholders. We recognize the effects of a tax position in the financial statements only if, as of the reporting date, it is “more likely than not” to be sustained based on its technical merits and their applicability to the facts and circumstances of the tax position. In making this assessment, we assume that the taxing authority will examine the tax position and have full knowledge of all relevant information. Accordingly, we have no liability for unrecognized tax benefits as of December 31, 2022 and 2021.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal and regulatory matters described below pertain to AB and are included here due to their potential significance to AB Holding’s investment in AB. With respect to all significant litigation matters, we consider the likelihood of a negative outcome. If we determine the likelihood of a negative outcome is probable and the amount of the loss can be reasonably estimated, we record an estimated loss for the expected outcome of the litigation. If the likelihood of a negative outcome is reasonably possible and we are able to determine an estimate of the possible loss or range of loss in excess of amounts already accrued, if any, we disclose that fact together with the estimate of the possible loss or range of loss. However, it is often difficult to predict the outcome or estimate a possible loss or range of loss because litigation is subject to inherent uncertainties, particularly when plaintiffs allege substantial or indeterminate damages. Such is also the case when the litigation is in its early stages or when the litigation is highly complex or broad in scope. In these cases, we disclose that we are unable to predict the outcome or estimate a possible loss or range of loss. On December 14th, 2022, four individual participants in the Profit Sharing Plan for Employees of AllianceBernstein L.P., (the "Plan" ) filed a class action complaint (the “Complaint” ) in the U.S. District Court for the Southern District of New York against AB, current and former members of the Compensation Committee of the Board of Directors, and the Investment and Administrative Committees under the Plan. Plaintiffs, who seek to represent a class of all participants in the Plan from December 14, 2016 to the present, allege that defendants violated their fiduciary duties and engaged in prohibited transactions under the Employee Retirement Income Security Act of 1974, as amended (" ERISA ") by including proprietary collective investment trusts as investment options offered under the Plan. The Complaint seeks unspecified damages, disgorgement and other equitable relief. AB is prepared to defend itself vigorously against these claims. While the ultimate outcome of this matter is currently not determinable given the matter remains in its early stages, we do not believe this litigation will have a material adverse effect on our results of operations, financial condition or liquidity. AB may be involved in various other matters, including regulatory inquiries, administrative proceedings and litigation, some of which may allege significant damages. It is reasonably possible that AB could incur losses pertaining to these matters, but management cannot currently estimate any such losses. Management, after consultation with legal counsel, currently believes that the outcome of any individual matter that is pending or threatened, or all of them combined, will not have a material adverse effect on our results of operations, financial condition or liquidity. However, any inquiry, proceeding or litigation has the element of uncertainty; management cannot determine whether further developments relating to any individual matter that is pending or threatened, or all of them combined, will have a material adverse effect on our results of operations, financial condition or liquidity in any future reporting period.

Business Combination and Asset Acquisition [Abstract]
Business Combination Disclosure	Acquisition On July 1, 2022, AB Holding acquired a 100% ownership interest in CarVal Investors L.P. (“ CarVa l”), a global private alternatives investment manager primarily focused on opportunistic and distressed credit, renewable energy, infrastructure, specialty finance and transportation investments that, as of the acquisition date, constituted approximately $12.2 billion in AUM. Also on July 1, immediately following the acquisition of CarVal, AB Holding contributed 100% of its equity interests in CarVal to AB in exchange for AB Units. Post-acquisition, CarVal was rebranded AB CarVal Investors (“ AB CarVal ”). On the acquisition date, AB Holding issued approximately 3.2 million AB Holding Units (with a fair value of $132.8 million), with the remaining 12.1 million Units (with a fair value of $456.4 million) issued on November 1, 2022. The fair value of the units issued on November 1, 2022 reflects final adjustments to the estimated unit issuance recorded as of acquisition close on July 1, 2022 and as disclosed in the third quarter 2022 Form 10-Q. AB received 100% equity interest in CarVal from AB Holding and issued approximately 15.3 million AB Units (with a fair value of $589.2 million). AB also recorded a contingent consideration payable of $228.9 million (to be paid predominantly in AB Units) based on CarVal achieving certain performance objectives over a six-year period ending December 31, 2027. The AB Units, as discussed above , were issued to AB Holding; AB Holding then issued the equal amount of AB Holding Units to CarVal. The excess of the purchase price over the current fair value of identifiable net liabilities acquired of $156.1 million (net of cash acquired of $40.8 million), resulted in the recognition of $671.2 million of goodwill and the recording of $303.0 million of finite-lived intangible assets primarily relating to investment management contracts and investor relationships with useful lives ranging from 5 to 10 years. As a result of the transfer of equity to AB, AB recorded a net deferred tax asset of $5.1 million, resulting in the recognition of $666.1 million of goodwill. The goodwill recorded is not deductible for tax purposes as the CarVal acquisition was an investment in a partnership. The following table summarizes the amounts of identified assets acquired and liabilities assumed at the acquisition date (reflecting acquisition adjustments recorded in the fourth quarter of 2022), as well as the consideration transferred to acquire CarVal (in thousands): Summary of purchase consideration: Fair value of AB Holding units issued $ 589,169 Fair value of contingent consideration 228,885 Total purchase consideration 818,054 Purchase price allocation: Assets acquired: Cash and cash equivalents $ 40,777 Receivables, net 82,523 Investments - other 947 Furniture, equipment, and leasehold improvements, net 2,464 Right-of-use assets 16,482 Other assets 10,600 Intangible assets 303,000 Goodwill 671,203 Total assets acquired 1,127,996 Liabilities assumed: Accounts payable and accrued expenses (17,793) Accrued compensation and benefits (219,726) Debt (42,661) Lease liabilities (16,571) Non-redeemable non-controlling interests in consolidated entities (13,191) Total liabilities assumed (309,942) Net assets acquired $ 818,054 The CarVal acquisition did not have a significant impact on our 2022 revenues and earnings. As a result, we have not provided supplemental pro forma financial information.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of the financial statements requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. AB Holding’s financial statements and notes should be read in conjunction with the consolidated financial statements and notes of AB, which are included in this Form 10-K.
Investment in AB	Investment in AB AB Holding records its investment in AB using the equity method of accounting. AB Holding’s investment is increased to reflect its proportionate share of income of AB and decreased to reflect its proportionate share of losses of AB and cash distributions made by AB to its Unitholders. In addition, AB Holding's investment is adjusted to reflect its proportionate share of certain capital transactions of AB.
Cash Distributions	Cash Distributions AB Holding is required to distribute all of its Available Cash Flow, as defined in the Amended and Restated Agreement of Limited Partnership of AB Holding (“ AB Holding Partnership Agreement ”), to its Unitholders pro rata in accordance with their percentage interests in AB Holding. Available Cash Flow is defined as the cash distributions AB Holding receives from AB minus such amounts as the General Partner determines, in its sole discretion, should be retained by AB Holding for use in its business (such as the payment of taxes) or plus such amounts as the General Partner determines, in its sole discretion, should be released from previously retained cash flow.
Long-term Incentive Compensation Plans	Long-term Incentive Compensation Plans AB maintains several unfunded, non-qualified long-term incentive compensation plans, under which the company grants awards of restricted AB Holding Units to its employees and members of the Board of Directors, who are not employed by AB or by any of AB’s affiliates (“ Eligible Directors ”).
