SHARES OF COMMON STOCK
This
prospectus supplement supplements the prospectus dated November 6, 2024, as amended by the prospectus dated May 13, 2025 (the “Prospectus”),
which forms a part of our registration statement on Form S-1 (No. 333-282536). This prospectus supplement is being filed to update and
supplement the information in the Prospectus with the information contained in our Form 8-K, filed with the Securities and Exchange Commission
(the “SEC”) on October 3, 2025 (the “Form 8-K”). Accordingly, we have attached the Form 8-K to
this prospectus supplement.
The
Prospectus relates to the offer and resale of up to 650,000 shares of our common stock, $0.0001 per share (the “Common Stock”),
by B. Riley Principal Capital II, LLC (the “Selling Stockholder”). The shares included in this Prospectus consist
of shares of Common Stock that we have issued or that we may, in our discretion, elect to issue and sell to the Selling Stockholder,
from time to time after the date of this Prospectus, pursuant to a Common Stock Purchase Agreement we entered into with the Selling Stockholder
on October 7, 2024 (the “Purchase Agreement”), in which the Selling Stockholder has committed to purchase from us,
at our direction, up to $50,000,000 of our Common Stock, subject to terms and conditions specified in the Purchase Agreement.
Our
Common Stock is listed on The Nasdaq Global Market (“Nasdaq”) under the symbol “SDST”. On October 20,
2025, the last reported sales price of our Common Stock was $5.27 per share.
We
are an “emerging growth company” as defined under U.S. federal securities laws and, as such, have elected to comply with
reduced public company reporting requirements. The Prospectus and this prospectus supplement comply with the requirements that apply
to an issuer that is an emerging growth company. This prospectus supplement updates and supplements the information in the Prospectus
and is not complete without, and may not be delivered or utilized except in combination with, the Prospectus, including any amendments
or supplements thereto. This prospectus supplement should be read in conjunction with the Prospectus and if there is any inconsistency
between the information in the Prospectus and this prospectus supplement, you should rely on the information in this prospectus supplement.
Investing
in our securities involves a high degree of risk. You should review carefully the risks and uncertainties described in the section titled
“Risk Factors” beginning on page 7 of the Prospectus, and under similar headings in any amendments or supplements
to the Prospectus.
Neither
the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities, or passed
upon the accuracy or adequacy of the Prospectus or this prospectus supplement. Any representation to the contrary is a criminal offense.
The
date of this prospectus supplement is October 22, 2025.

Item
3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.
As
previously reported in a Current Report on Form 8-K, filed with the Securities and Exchange Commission (the “Commission”)
on April 8, 2025, Stardust Power Inc., a Delaware corporation (the “Company”) received Notice from Nasdaq indicating
that, because the market value of the Company’s Common Stock had been below $50,000,000 for 30 consecutive business days, the Company
no longer complied with the minimum market value of listed securities requirement for continued listing on the Nasdaq Global Market under
Rule 5450(b)(2)(A) of Nasdaq Listing Rules (the “MVLS Rule”).
The
Company was provided with an initial compliance period of 180 calendar days, or until September 30, 2025, to regain compliance with the
MVLS Rule. The Company did not regain compliance with the MVLS Rule during the allotted time period.
Accordingly,
on October 1, 2025, the Company received a staff delist determination letter from the Nasdaq Listing Qualifications Department, as a
result of its failure to regain compliance with the MVLS Rule.
The
Company intends to timely request a hearing before a Nasdaq Hearings Panel (the “Panel”). This hearing request will
automatically stay Nasdaq’s delisting of the Company’s common stock and warrants pending the Panel’s decision and any
extension provided by the Panel. The Company intends to present its plan of compliance, which may include a transfer to the Nasdaq Capital
Market listing tier.
As
previously reported by Stardust on March 24, 2025, the Company received deficiency letters from the Staff on March 18, 2025, and March
19, 2025, notifying the Company that it was not in compliance with (i) Nasdaq Listing Rule 5450(b)(2)(C) requiring a listed company to
maintain a minimum Market Value of Publicly Held Shares, as defined by Nasdaq, of $15 million and (ii) Nasdaq Listing Rule 5450(a)(1)
requiring a listed company to maintain a minimum bid price of $1.00 per share, respectively (such requirements, the “Listing
Requirements”). In accordance with Nasdaq rules, the Company successfully achieved compliance with these Listing Requirements
within the stipulated given period of 180 calendar days (or by/until September 15, 2025).
Forward
Looking Statements
This
current report contains forward-looking statements, including, but not limited to, the timing of the hearing and the timing of the decision
of the Panel. Such statements are subject to risks and uncertainties, and actual results may differ materially from those expressed or
implied by such forward-looking statements. In particular, the hearing may be scheduled, and the Panel may issue a decision, more quickly
than expected, which shorter timeline(s) may be unfavorable for the Company and the continued listing of the Company’s common stock
on The Nasdaq Capital Market. Investors are cautioned not to place undue reliance on these forward-looking statements, which speak only
as of the date of this report. The Company undertakes no obligation to update any forward-looking statement in this report, except as
required by law.
