PROSPECTUS SUPPLEMENT

(To the Prospectus dated March 21, 2025)

<div align='center'>X3 Holdings Co., Ltd.

60,000,000 Class A Ordinary Shares</div>

Pursuant to this prospectus
supplement and the accompanying prospectus and a securities purchase agreement dated July 11, 2025 (the “Securities Purchase
Agreement”), we are offering 60,000,000 Class A ordinary shares of the Company, with a par value of US$$0.00003 per
share (the “Class A Ordinary Shares”), at a purchase price of US$0.43 per share to 18 individual investors (collectively referred
to as the “Investors”). For a more detailed description of our Ordinary Shares, see the section entitled “Description
Of Securities We Are Offering” on page S-21.

Our Class A Ordinary Shares
are listed on the Nasdaq Capital Market (“Nasdaq”) under the symbol “XTKG.” On July 15, 2025, the closing price
of our Class A Ordinary Shares on Nasdaq was US$1.76 per Ordinary Share.

The aggregate market value
of our outstanding Ordinary Shares held by non-affiliates, or public float, as of June 23, 2025, was approximately $79.3 million, which
was calculated based on 36,046,661 Ordinary Shares held by non-affiliates and the price of $2.20 per Ordinary Share, which was the closing
price of our Ordinary Shares on Nasdaq on June 23, 2025. We are therefore currently not subject to the limitations under General Instruction I.B.5 of Form F-3.

We are an “emerging
growth company” as defined under the applicable U.S. securities laws and are eligible for reduced public company reporting requirements.

In this prospectus supplement,
“we,” “us,” “our company,” “the Company” and “our” refer to X3 Holdings Co.,
Ltd. and its subsidiaries and consolidated affiliated entities, and in the context of describing our consolidated financial information.

Investing in our securities involves a significant degree of risk.
