 Exhibit 10.6 

PRIVATE PLACEMENT UNITS PURCHASE AGREEMENT 

This PRIVATE PLACEMENT UNITS PURCHASE AGREEMENT (this “Agreement”) is made as of the 30th day of September, 2021, by and between
Marblegate Acquisition Corp., a Delaware corporation (the “Company”) and Cantor Fitzgerald & Co. (the “Subscriber”). 

WHEREAS, the Company desires to sell to the Subscriber on a private placement basis (the “Offering”) an aggregate of 300,000 units
(the “Units”) of the Company, each Unit comprised of one share of Class A common stock of the Company, par value $0.0001 per share (“Common Stock”) and one-half of one warrant, each
whole warrant exercisable to purchase one share of Common Stock (“Warrant”), for a purchase price of $10.00 per Unit. The shares of Common Stock underlying the Warrants are hereinafter referred to as the “Warrant Shares.” The
shares of Common Stock underlying the Units (excluding the Warrant Shares) are hereinafter referred to as the “Placement Shares.” The Warrants underlying the Units are hereinafter referred to as the “Placement Warrants.” The
Units, Placement Shares, Placement Warrants and Warrant Shares, collectively, are hereinafter referred to as the “Securities.” Each whole Placement Warrant is exercisable to purchase one share of Common Stock at an exercise price of $11.50
during the period commencing on the later of (i) twelve (12) months from the date of the closing of the Company’s initial public offering of units (the “IPO”) and (ii) thirty (30) days following the consummation of
the Company’s initial business combination (the “Business Combination”), as such term is defined in the registration statement in connection with the IPO, as amended, at the time it becomes effective (the “Registration
Statement”), and expiring on the fifth (5th) anniversary of the consummation of the Business Combination (provided that so long as the Placement Warrants are held by the Subscriber or its
designees, the Subscriber or its designees will not be permitted to exercise such Placement Warrants after the five-year anniversary of the effective date of the Registration Statement); and 

WHEREAS, the Subscriber wishes to purchase 300,000 Units, and the Company wishes to accept such subscription from the Subscriber. 

NOW, THEREFORE, in consideration of the premises and the mutual covenants hereinafter set forth and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Company and Subscriber hereby agree as follows: 
 1. Agreement to Subscribe 

1.1. Purchase and Issuance of the Units. Upon the terms and subject to the conditions of this Agreement, the Subscriber hereby agrees to
purchase from the Company, and the Company hereby agrees to sell to the Subscriber, on the Closing Date (as defined below) the Units in consideration of the payment of the Purchase Price (as defined below). On the Closing Date, the Company shall, at
its option, deliver to the Subscriber the certificates representing the Securities purchased or effect such delivery in book-entry form. 

1.2. Purchase Price. As payment in full for the Units being purchased under this Agreement, the Subscriber shall pay $3,000,000 (the
“Purchase Price”) by wire transfer of immediately available funds or by such other method as may be reasonably acceptable to the Company, to the trust account (the “Trust Account”) at a financial institution to be chosen by the
Company, maintained by Continental Stock Transfer & Trust Company, acting as trustee (“Continental”), on or prior to the Closing Date. 

1.3. Closing. The closing of the purchase and sale of the Units shall take place simultaneously with the closing of the IPO (the
“Closing Date”). The closing of the purchase and sale of the Units shall take place at the offices of Ellenoff Grossman & Schole LLP, 1345 Avenue of the Americas, 11th Floor, New York, New York, 10105, or such other place as may
be agreed upon by the parties hereto. 
 1.4 Conditions to Closing. The obligation of the Subscriber to purchase and pay for the Units
as provided herein shall be subject to the satisfaction of the conditions set forth in Section 4 of the Underwriting Agreement, dated as of the date hereof, by and between the Company and the Subscriber, as representative of the underwriters
named therein (the “Underwriting Agreement”). 

  
 1 













 1.5 Termination. This Agreement and each of the obligations of the undersigned shall
be null and void and without effect if a Closing does not occur prior to December 31, 2021. 
 2. Representations and Warranties of Subscriber

 Subscriber represents and warrants to the Company that: 

2.1. No Government Recommendation or Approval. Subscriber understands that no federal or state agency has passed upon or made any
recommendation or endorsement of the Company or the Offering of the Securities. 
 2.2. Accredited Investor. Subscriber represents
that it is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”), and acknowledges that the sale contemplated hereby is being made in
reliance, among other things, on a private placement exemption to “accredited investors” under the Securities Act and similar exemptions under state law. 

2.3. Intent. Subscriber is purchasing the Securities solely for investment purposes, for Subscriber’s own account (and/or for the
account or benefit of its members or affiliates, as permitted, pursuant to the terms hereof), and not with a view to the distribution thereof. 

2.4. Restrictions on Transfer. Subscriber acknowledges and understands the Units are being offered in a transaction not involving a
public offering in the United States within the meaning of the Securities Act. The Securities have not been registered under the Securities Act and, if in the future Subscriber decides to offer, resell, pledge or otherwise transfer the Securities,
such Securities may be offered, resold, pledged or otherwise transferred only (A) pursuant to an effective registration statement filed under the Securities Act, (B) pursuant to an exemption from registration under Rule 144 promulgated
under the Securities Act, if available, or (C) pursuant to any other available exemption from the registration requirements of the Securities Act, and in each case in accordance with any applicable securities laws of any state or any other
jurisdiction. Notwithstanding the foregoing, Subscriber acknowledges and understands the Securities are subject to transfer restrictions as described in Section 8 hereof. Subscriber agrees that if any transfer of its Securities or any interest
therein is proposed to be made, as a condition precedent to any such transfer, Subscriber may be required to deliver to the Company an opinion of counsel satisfactory to the Company with respect to such transfer. Absent registration or another
available exemption from registration, Subscriber agrees it will not resell the Securities (unless otherwise permitted pursuant to the terms hereof). Subscriber further acknowledges that because the Company is a shell company, Rule 144 may not be
available to Subscriber for the resale of the Securities until the one year anniversary following consummation of the initial Business Combination of the Company, despite technical compliance with the requirements of Rule 144 and the release or
waiver of any contractual transfer restrictions. 
 2.5. Sophisticated Investor. 

(i) Subscriber is sophisticated in financial matters and is able to evaluate the risks and benefits of the investment in the
Securities. 
 (ii) Subscriber is aware that an investment in the Securities is highly speculative and subject to substantial
risks because, among other things, (a) the Securities are subject to transfer restrictions and have not been registered under the Securities Act and therefore cannot be sold unless subsequently registered under the Securities Act or an
exemption from such registration is available and (b) Subscriber has waived its redemption rights with respect to the Securities as set forth in Section 5 hereof, and the Securities held by the Subscriber are not entitled to, and have no
right, interest or claim to any monies held in the Trust Account, and accordingly Subscriber may suffer a loss of a portion or all of its investment in the Securities. Subscriber is able to bear the economic risk of its investment in the Securities
for an indefinite period of time. 
 2.6. Organization and Authority. Subscriber is duly organized, validly existing and in good
standing under the laws of its state of incorporation or formation and it possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement. 

  
 2 













 2.7. Authority. This Agreement has been validly authorized, executed and delivered by
Subscriber and is a valid and binding agreement enforceable in accordance with its terms, subject to the general principles of equity and to bankruptcy or other laws affecting the enforcement of creditors’ rights generally. 

2.8. No Conflicts. The execution, delivery and performance of this Agreement and the consummation by Subscriber of the transactions
contemplated hereby do not violate, conflict with or constitute a default under (i) Subscriber’s charter documents, (ii) any agreement or instrument to which Subscriber is a party or (iii) any law, statute, rule or regulation to
which Subscriber is subject, or any agreement, order, judgment or decree to which Subscriber is subject. 
 2.9. No Legal Advice from
Company. Subscriber acknowledges it has had the opportunity to review this Agreement and the transactions contemplated by this Agreement and the other agreements entered into between the parties hereto with Subscriber’s own legal counsel
and investment and tax advisors. Except for any statements or representations of the Company made in this Agreement and the other agreements entered into between the parties hereto, Subscriber is relying solely on such counsel and advisors and not
on any statements or representations of the Company or any of its representatives or agents for legal, tax or investment advice with respect to this investment, the transactions contemplated by this Agreement or the securities laws of any
jurisdiction. 
 2.10. Reliance on Representations and Warranties. The Subscriber understands the Units are being offered and sold to
the Subscriber in reliance on exemptions from the registration requirements under the Securities Act, and analogous provisions in the laws and regulations of various states, and that the Company is relying upon the truth and accuracy of the
representations, warranties, agreements, acknowledgments and understandings of the Subscriber set forth in this Agreement in order to determine the applicability of such provisions. 

2.11. No General Solicitation. Subscriber is not subscribing for the Units as a result of or subsequent to any general solicitation or
general advertising, including but not limited to any advertisement, article, notice or other communication published in any newspaper, magazine, or similar media or broadcast over television or radio, or presented at any seminar or meeting or in a
registration statement with respect to the IPO filed with the Securities and Exchange Commission (“SEC”). 
 2.12. Legend.
Subscriber acknowledges and agrees the certificates evidencing each of the Securities shall bear a restrictive legend (the “Legend”), in form and substance substantially as set forth in Section 4 hereof.
