Secondary offering of up to 32,157,957 Class A ordinary shares offered by the Selling Shareholder

This Prospectus Supplement updates, amends and supplements the prospectus dated May 29, 2026 (the “Original Prospectus”), contained in our Registration Statement on Form F-1, effective as of May 29, 2026 (Registration No. 333-290527) (the “Registration Statement”), relating to the offering of up to 32,157,957 Class A ordinary shares issuable pursuant to the Ordinary Share SPA for up to an aggregate purchase price of up to $73.0 million by the Selling Shareholder (each as defined below).

The Selling Shareholder may, from time to time, sell the Class A ordinary shares offered by them described in the Original Prospectus. We will not receive any proceeds from the sale of Class A ordinary shares by the Selling Shareholder. We will bear all costs, expenses and fees in connection with the registration of the Selling Shareholder’s Class A ordinary shares. The Selling Shareholder will pay any underwriting discounts and commissions and expenses incurred by the Selling Shareholder for brokerage, accounting, tax or legal services or any other expenses incurred by the Selling Shareholder in disposing of their Class A ordinary shares.

On November 24, 2025, the parties amended the Ordinary Share SPA, to provide that at the Company’s option, the Company may sell the VWAP Purchase Shares either (i) at a price per share equal to (x) 0.95, multiplied by (y) the lower of (A) the Closing Sale Price on the applicable Trading Day and (B) the VWAP on the applicable Trading Day during a one (1)- day VWAP Purchase Valuation Period (as defined in the Ordinary Share SPA) or (ii) at a price per share equal to (x) 0.97, multiplied by (y) the lowest VWAP of the Class A ordinary shares during a three (3)- day VWAP Purchase Valuation Period.

Additionally, the VWAP Purchase Maximum Amount (as defined in the Ordinary Shares SPA) was amended to provide that the Company’s right to direct the Selling Shareholder to purchase Class A ordinary shares under the Ordinary Share SPA shall be limited to the amount of shares equal to the lower of: (i) the product (rounded up or down to the nearest whole number) obtained by multiplying (A) the daily trading volume in the Class A ordinary shares on the Trading Market (or Eligible Market, as applicable) on the applicable VWAP Purchase Exercise Date for such VWAP Purchase by (B) 0.20; and (ii) the quotient obtained by dividing (A) $2,000,000, by (B) the VWAP on the VWAP Purchase Exercise Date, and (b) respect to a VWAP Purchase made pursuant to Section 3.1 where the VWAP Purchase Valuation Period consists of three (3) Trading Days, such number of Class A ordinary shares equal to the lower of (i) the product (rounded up or down to the nearest whole number) obtained by multiplying (A) the daily trading volume in the Class A ordinary shares on the Trading Market (or Eligible Market, as applicable) on the applicable VWAP Purchase Exercise Date for such VWAP Purchase by (B) 0.40; and (ii) the quotient obtained by dividing (A) $3,000,000, by (B) the VWAP on the VWAP Purchase Exercise Date (in each case to be appropriately adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction during the applicable period); provided however, that the Selling Shareholder may waive this limit if Form F-3 is being used to register the Registrable Securities (as defined in the Registration Rights Agreement). All capitalized terms not defined in this paragraph shall have the meanings ascribed to them in the Ordinary Share SPA, as amended.

On August 29, 2025, Blue Gold Limited (the “Company”) entered into an Ordinary Share Purchase Agreement with Tumim Stone Capital LLC (the “Ordinary Share SPA”), pursuant to which the Company may, at its option, issue and sell up to an aggregate principal amount of $75 million in Class A ordinary shares, subject to certain conditions. In consideration for entering into the Ordinary Share SPA, on September 3, 2025, the Company issued 69,419 Class A ordinary shares (the “Commitment Shares”). Since such date and up to the date of this Prospectus Supplement, the Company has issued an additional 2,245,713 Class A ordinary shares pursuant to the Ordinary Share SPA. The Class A ordinary shares may be sold and issued by the Company at a price per share equal to 0.97 multiplied by the lowest daily volume-weighted average price (VWAP) of the Class A ordinary shares during the applicable VWAP Purchase Valuation Period (as defined in the Ordinary Share SPA), provided that the parties to the Ordinary Share SPA may mutually agree to a different price if a Form F-3 is being used to register the VWAP Purchase Shares (as defined below). Tumim Stone Capital LLC is referred to herein as the “Selling Shareholder.”

This Registration Statement and the related Original Prospectus and this Prospectus Supplement relates to the offer and resale from time to time of up to 32,157,957 Class A ordinary shares issuable pursuant to the Ordinary Share SPA (the “VWAP Purchase Shares”) for up to an aggregate purchase price of up to $73.0 million by the Selling Shareholder.

INFORMATION CONTAINED IN THIS REPORT

Notification of Nasdaq Listing Deficiencies

On July 24, 2026, Blue Gold Limited (the “Company”) received a written notification (the “Notification Letter”) from the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) advising the Company that, based on Nasdaq’s review of the Company’s Market Value of Publicly Held Shares (“MVPHS”) for the last 30 consecutive business days (June 10, 2026 through July 23, 2026), the Company no longer satisfies the minimum MVPHS requirement of $15,000,000 for continued listing on The Nasdaq Global Market, as required under Nasdaq Listing Rules 5450(b)(2) and 5450(b)(3)(C).

The Notification Letter does not result in the immediate delisting of the Company’s Class A Ordinary Shares (Nasdaq: BGL) from The Nasdaq Global Market. In accordance with Nasdaq Listing Rule 5810(c)(3)(D), the Company has been provided a compliance period of 180 calendar days, or until January 20, 2027, to regain compliance with the MVPHS requirement. To regain compliance, the Company’s MVPHS must close at $15,000,000 or more for a minimum of ten consecutive business days during the compliance period. Nasdaq’s staff may, in its discretion, require that the Company maintain a MVPHS of at least $15,000,000 for up to 20 consecutive business days pursuant to Nasdaq Listing Rule 5810(c)(3)(H).

Pursuant to Nasdaq Listing Rule 5810(b), the Company is required to make a public announcement disclosing receipt of the Notification Letter no later than four business days from the date of the letter. In satisfaction of this requirement, the Company is furnishing a press release, dated July 27, 2026, which is attached hereto as Exhibit 99.1 and incorporated herein by reference.

In addition, under Nasdaq Listing Rule 5505, the Company may alternatively apply to transfer its listing to The Nasdaq Capital Market, provided it meets that market’s continued listing requirements and pays the applicable application fee under Nasdaq Listing Rule 5920(a)(11). If the Company does not regain compliance before the expiration of the compliance period on January 20, 2027, the Company will receive written notification that its securities are subject to delisting, at which time the Company may appeal the delisting determination to a Nasdaq Hearings Panel.

The Company intends to actively monitor its MVPHS during the compliance period and evaluate available options to regain compliance, which may include pursuing actions to increase the market value of publicly held shares or, alternatively, applying to transfer its listing to The Nasdaq Capital Market. The Notification Letter has no immediate effect on the listing or trading of the Company’s Class A Ordinary Shares on Nasdaq, and the Company’s securities will continue to trade under the symbol “BGL.”

Exhibit 99.1

Blue Gold Announces Receipt of Nasdaq Notification Regarding Minimum Market Value of Publicly Held Shares Deficiency

NEW YORK, NY, July 27, 2026 /PRNewswire/ — Blue Gold Limited (Nasdaq: BGL) (Nasdaq: BGLWW) (“Blue Gold” or the “Company”), a gold mining company with the infrastructure to deliver gold from mine-to-wallet, today announced that the Company received a notification letter (the “Notification Letter”) from the Listing Qualifications Department of the Nasdaq Stock Market LLC (“Nasdaq”), notifying the Company that it is currently not in compliance with the minimum Market Value of Publicly Held Shares (“MVPHS”) requirement set forth under Nasdaq Listing Rule 5550(b)(2).

Nasdaq Listing Rule 5450(b)(3)(C) requires companies listed on the Nasdaq Global tier to maintain a minimum MVPHS of US$15 million and Nasdaq Listing Rule 5810(c)(3)(D) provides that a deficiency exists if a company fails to meet the minimum MVPHS requirement for a period of 30 consecutive business days. Based on the market value of the Company from June 10, 2026, to July 23, 2026, the Company no longer meets the minimum market value requirement.

The Notification Letter does not impact the Company’s listing on The Nasdaq Capital Market at this time. In accordance with Nasdaq Listing Rule 5810(c)(3)(D), the Company has been provided 180 calendar days, or until January 20, 2027, to regain compliance with Nasdaq Listing Rule 5540(b)(3)(C). To regain compliance, the Company’s MLPHS must closed at $15,000,000 or more for a minimum of 10 consecutive business days. In the event the Company does not regain compliance by January 20, 2027, the Company may be eligible for additional time to regain compliance or may face delisting. In the event of such a notification, the Nasdaq rules permit the Company an opportunity to appeal Nasdaq’s determination.

The Company’s business operations are not affected by the receipt of the Notification Letter. The Company intends to actively monitor its MVPHS and evaluate available options to regain compliance within the applicable compliance period. As part of this process, the Company currently intends to apply to transfer its listing to The Nasdaq Capital Market, subject to meeting the applicable continued listing requirements.
