Titles of Securities Being Registered:

This Post-Effective Amendment No. 323 to Registration File Nos. 002-19458/811-01136 includes the following:

EXPLANATORY NOTE

Post-Effective Amendment No. 299 ("PEA 299") was filed with the U.S. Securities and Exchange Commission ("SEC") via the EDGAR system pursuant to Rule 485(a)(2) on January 15, 2026 (Accession Number 0001193125-26-014246) to be effective 75 days after filing and was most recently delayed until June 14, 2026 by Post-Effective Amendment No. 317 filed on May 14, 2026 (Accession Number 0002071844-26-000511).

Pursuant to Rule 485(b)(1)(iii) of the Securities Act of 1933, as amended, this Post-Effective Amendment No. 323 ("PEA 323") to the Registration Statement for the Guggenheim Funds Trust (the "Registrant") is being filed solely for the purpose of delaying the effectiveness of PEA 299 relating to the Guggenheim Core Plus Bond ETF series of the Registrant. This PEA 323 relates only to the Guggenheim Core Plus Bond ETF and does not otherwise delete, amend, or supersede any information relating to any other series of the Registrant.

Accordingly, the prospectus and statement of additional information of the Registrant as filed in PEA 299 are incorporated herein by reference in their entirety into this filing. As stated on the cover page to this filing, this PEA 323 is being filed for the sole purpose of designating July 14, 2026 as the new date upon which PEA 299 shall become effective.

The Board of Trustees of the Registrant is the same as the board of certain other registrants, each of which has Guggenheim Partners Investment Management, LLC ("GPIM"), or an affiliate of GPIM, as its investment adviser. In addition, the officers of the Registrant are substantially identical to those of the other registrants. Nonetheless, the Registrant takes the position that it is not under common control with the other registrants because the power residing in the respective boards and officers arises as the result of an official position with the respective registrants.

The Trust through Guggenheim Macro Opportunities Fund, a separate series of the Trust, wholly owns and controls the Guggenheim Macro Opportunities Fund CFC ("Subsidiary"), a company organized under the laws of the Cayman Islands. The Subsidiary's financial statements will be included, on a consolidated basis, in the Fund's report on Form N-CSR.

Article VII, Section III of the Registrant's Amended and Restated Declaration of Trust, which is filed with the Registrant's Post Effective Amendment No. 282 on January 28, 2021, provides for indemnification of the Trustees, officers, employees and other agents of the Registrant who are parties pursuant to any proceeding by reason of their actions performed in their scope of service on behalf of the Trust.

A policy of insurance covering Guggenheim Funds Distributors, LLC, the Registrant and certain other registrants advised by GPIM, or an affiliate of GPIM insures the Registrant's trustees and officers against liability arising by reason of an alleged breach of duty caused by any negligent act, error or accidental omission in the scope of their duties. The independent trustees are also covered under a joint independent directors liability ("IDL") insurance policy that covers the independent trustees of the other registrants.

Insofar as indemnification for liability arising under the Securities Act of 1933, as amended ("1933 Act"), may be permitted to trustees, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a trustee, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such trustee, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

GPIM serves as investment adviser for each series of the Trust. GPIM is primarily engaged in the provision of investment advisory and management services to registered investment companies, separately managed accounts, collective investment trusts and private funds. The directors and officers of GPIM consist primarily of persons who during the past two years have been active in the investment management business. To the knowledge of the Registrant, except as set forth below, as applicable, none of the directors or executive officers of GPIM is or has been at any time during the past two fiscal years engaged in any other business, profession, vocation or employment of a substantial nature. Information as to the executive officers and directors of GPIM is included in its Form ADV as filed with the SEC (File No. 801-66786) pursuant to the Investment Advisers Act of 1940, as amended, which is incorporated herein by reference.

(a) Guggenheim Funds Distributors, LLC serves as the principal underwriter for the Registrant, Guggenheim Strategy Funds Trust, Guggenheim Variable Funds Trust, Rydex Series Funds, Rydex Variable Trust and Rydex Dynamic Funds.

(b) The following information is furnished with respect to the directors and officers of Guggenheim Funds Distributors, LLC:
