On August 22, 2025, Mercurity Fintech Holding Inc. (the “Company”) published an announcement (the “Press Release”), a copy of which is attached herein as Exhibit 99.1.

This report on Form 6-K (including the exhibits hereto) shall not be deemed to be “filed” for purposes of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and shall not be incorporated by reference into any filing under the Securities Act of 1933, as amended, except as shall be expressly set forth by specific reference in such filing.

Forward-LookingStatements

This Form 6-K includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. The Company’s actual results may differ from its expectations, estimates and projections and consequently, you should not rely on these forward-looking statements as predictions of future events. Words such as “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,” “could,” “should,” “believe,” “hope,” “predict,” “potential,” “continue,” and similar expressions are intended to identify such forward-looking statements. These forward-looking statements include the Company’s expectations with respect to future performance and involve significant risks and uncertainties that could cause the actual results to differ materially from the expected results. Most of these factors are outside the Company’s control and are difficult to predict. Factors that may cause such differences include but are not limited to risks and uncertainties incorporated by reference under “Risk Factors” in the Company’s Form 20-F (SEC File No. 001-36896) filed with the SEC on April 30, 2025 and in the Company’s other filings with the SEC. The Company cautions that the foregoing list of factors is not exclusive. The Company cautions readers not to place undue reliance upon any forward-looking statements, which speak only as of the date made. The Company does not undertake or accept any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements to reflect any change in its expectations or any change in events, conditions, or circumstances on which any such statement is based.

Exhibit99.1

MercurityFintech Expands Institutional Ownership with BlackRock, State Street, and Vanguard Following Russell 2000® Inclusion

NewYork, NY, Aug. 22, 2025 (GLOBE NEWSWIRE) — Mercurity Fintech Holding Inc. (the “Company,” “we,” “us,” “our company,” or “MFH”) (Nasdaq: MFH), a blockchain-powered fintech group, today announced that a broad range of institutional investors reported holdings in MFH in their latest regulatory filings.

Recent 13F and related regulatory disclosures report institutional positions in MFH by major index and asset managers, global banks, and ETF sponsors, reflecting a larger and more diverse institutional holder base for MFH compared to prior periods. Reported filers include BlackRock, Geode Capital Management, State Street, Vanguard, Northern Trust, and others. The Company has also observed that several notable pension funds – including the California State Teachers’ Retirement System, the Police and Firemen’s Retirement System of New Jersey, and the New York State Common Retirement Fund – have also slightly increased their holdings of the Company’s stock.

Both new filers and additional positions from existing institutions contributed to the increase in institutional exposure, and largely follow the Company’s inclusion in the Russell 2000 index. Russell indexes are widely used by investment managers for index funds and are commonly employed as benchmarks for active investment strategies.

Though these index-driven acquisitions are primarily mechanical, reflecting index-related or passive investment activity, and should not be viewed as a strategic endorsement of the Company, MFH views the expanding institutional presence as a meaningful acknowledgement of its fintech and digital asset platform development.

“Having more institutional investors on board is exciting for us,” said Shi Qiu, CEO of MFH. “It not only brings more liquidity to our stock but also puts us in front of a wider investment community. While we understand much of this activity is potentially index-related, we’re confident that as we continue building out our fintech capabilities and delivering results, these relationships will deepen.”

Aboutthe filings

The summary above draws on Form 13F and related regulatory filings reported in early to mid-August 2025. Institutional holdings can change at any time, may be reported through multiple affiliated entities, and many positions are passive. References to institutional names are based solely on publicly available filings and are provided for informational purposes only.

The inclusion of MFH in institutional portfolios does not necessarily represent an investment recommendation or active investment decision. MFH does not disclose or comment on the specific size of any investor’s holdings.
