This
prospectus supplement supplements the prospectus dated May 5, 2025 (the “Prospectus”), which forms a part of our registration
statement on Form S-1 (No. 333-281160). 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
21, 2025 (the “Form 8-K”). Accordingly, we have attached the Form 8-K to this prospectus supplement.
The
Prospectus and this prospectus supplement relate to the offer and resale from time to time by the selling securityholders named in this
Registration Statement or their permitted transferees (the “Selling Securityholders”) of the following:
(i)
up to 5,519,087 shares of common stock, par value $0.0001 per share (the “Common Stock”), consisting of:
| (a) |
up
to 12,777 shares of Common Stock issued to former GPAC II Public Shareholders (as defined in the Prospectus) at Closing (as defined
in the Prospectus) pursuant to certain Non-Redemption Agreements (as defined in the Prospectus); |
| |
|
| (b) |
up
to 400,000 shares of Common Stock (including 100,000 shares that are subject to forfeiture) issued to the Sponsor at Closing
in exchange for an equivalent number of Class B ordinary shares, par value $0.0001 per share,
of GPAC II that were originally purchased for approximately $0.03 per share; |
| |
|
| (c) |
up
to 107,754 shares of Common Stock issued to PIPE Investors (as defined in the Prospectus) at Closing pursuant to certain PIPE Subscription
Agreements (as defined in the Prospectus) at a purchase price of $93.50 per share; |
| |
|
| (d) |
up
to 202,498 shares of Common Stock held by holders of vested RSU awards; |
| |
|
| (e) |
up
to 4,239,390 shares of Common Stock issued to certain third parties and affiliates of Stardust Power at Closing (which in each case
were issued as consideration in the Business Combination (as defined in the Prospectus) based on a value of $100.00 per share); and |
| |
|
| (f) |
up
to 556,666 shares of Common Stock issuable upon exercise of the Private Warrants (as defined in the Prospectus); and |
(ii)
up to 5,566,667 Private Warrants, which were originally purchased at a price of $1.50 per Private Warrant.
We
will not receive any proceeds from the sale of shares of Common Stock or Warrants (as defined in the Prospectus) by the Selling Securityholders
pursuant to the Prospectus or in any supplement to the Prospectus, except upon the exercise of Warrants.
The
shares of Common Stock, not including Common Stock issuable upon exercise of the Warrants, being offered for resale pursuant to the Prospectus
or in any supplement to the Prospectus by the Selling Securityholders represent approximately 91.74% of shares of Common Stock (and assuming
the exercise of all Warrants, 93.15% of Common Stock) outstanding as of April 28, 2025. Given the substantial number of shares of Common
Stock being registered for potential resale by Selling Securityholders pursuant to the Prospectus and this prospectus supplement, the
sale of shares of Common Stock or Warrants by the Selling Securityholders, or the perception in the market that the Selling Securityholders
of a large number of holders of Common Stock or Warrants intend to sell such securities, could increase the volatility of the market
price of our Common Stock or Warrants or result in a significant decline in the public trading price of our Common Stock or Warrants.
Even if our trading price of Common Stock is significantly below $100.00 per share, the offering price for the units offered in the IPO
(as defined in the Prospectus), certain of the Selling Securityholders may still have an incentive to sell shares of Common Stock, because
they purchased the shares at prices lower than the public investors or the current trading price of our Common Stock.
We
will only receive proceeds from the exercise of Warrants if and when the holders of the Warrants choose to exercise them. The exercise
of the Warrants, and any proceeds we may receive from their exercise, are highly dependent on the price of our Common Stock and the spread
between the exercise price of the Warrants and the price of our Common Stock at the time of exercise. If the market price of our Common
Stock is less than the exercise price of a holder’s Warrants, it is unlikely that holders will choose to exercise. There can be
no assurance that the Warrants will be in the money prior to their expiration. In addition, our Warrant holders have the option to exercise
the Warrants on a cashless basis in certain circumstances. See “Description of Securities - Warrants” in the Prospectus.
As such, it is possible that we may never generate any cash proceeds from the exercise of our Warrants.
We
will bear all costs, expenses and fees in connection with the registration of the securities. The Selling Securityholders will bear all
commissions and discounts, if any, attributable to their respective sales of the securities.
Our
registration of the securities covered by the Prospectus or in any prospectus supplement does not mean that either we or the Selling
Securityholders will issue, offer or sell, as applicable, any of the Common Stock. The Selling Securityholders may offer and sell the
securities covered by the Prospectus or in any prospectus supplement in a number of different ways and at varying prices. We provide
more information about how the Selling Securityholders may sell the shares in the section entitled “Plan of Distribution”
in the Prospectus.
You
should read the Prospectus, this prospectus supplement and any prospectus supplement or amendment carefully before you invest in our
Common Stock or Warrants.
Our
Common Stock and Warrants are listed on The Nasdaq Global Market (“Nasdaq”) under the symbols “SDST” and
“SDSTW,” respectively. On October 20, 2025, the last reported sales price of our Common Stock was $5.27 per share and the
last reported sales price of our Warrants was $0.151 per Warrant.
We
are an “emerging growth company” and a “smaller reporting 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 and a smaller reporting 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 14 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.

Stardust
Power Secures Strategic North American Lithium Supply with Prairie Lithium
GREENWICH,
Conn. – October 21, 2025 – Stardust Power Inc. (NASDAQ: SDST) (“Stardust Power” or the “Company”),
an American developer of battery-grade lithium carbonate, announced today that it has executed a Letter of Intent (the “Agreement”)
with Prairie Lithium for the supply of 6,000 metric tons per annum of lithium carbonate equivalent (“LCE”) in the form of
lithium chloride (“LiCl”). The lithium chloride is sourced from the Prairie Lithium Project in Saskatchewan, Canada and will
be used as feedstock at Stardust Power’s lithium processing facility in Muskogee, Oklahoma. This Agreement marks a significant
source of supply as the Company eyes a Final Investment Decision (“FID”) and the start of major construction.
The
supply Agreement with Prairie Lithium provides a foundation for near-term feedstock that enables the Company to accelerate its business
model, strengthen customer engagement, and further de-risk the development of Phase 1. This Agreement also preserves flexibility for
future phases to incorporate multiple chlorides as production scales. A key strength of Stardust Power’s strategy lies in its large
central refinery engineered to process multiple approved lithium chloride inputs. This design enables efficient aggregation of feedstock
and scalable production of battery-grade lithium carbonate. Supporting this approach, the Company continues to work with multiple producers
and developers to bring their products to market, positioning itself as a critical hub in North America’s lithium supply chain.
Under
the Agreement, feedstock will be delivered to the Port of Muskogee’s Free Trade Zone, which offers strategic access to established
water, road, and rail networks. The Free Trade Zone designation provides potential advantages such as tariff exemptions and reduced import
duties. Initial deliveries are scheduled to begin as early as 2027, with volumes scaling up to 6,000 metric tons per annum with the opportunity
for additional volumes. Prairie Lithium’s Preliminary Economic Statement identifies up to 17,000 metric tons per annum of production
capacity. Early shipments can be stored in on-site tanks to build sufficient reserves for commissioning and ramp-up of the facility,
with ongoing storage maintained to ensure uninterrupted supply. The Agreement is non-binding and subject to negotiation and execution
of a definitive agreement. The Agreement spans an initial six-year term, with two additional six-year extension options at Stardust Power’s
discretion, enabling up to 18 years of secure, feedstock supply.
“Securing
reliable, high-quality feedstock is critical to scaling our lithium refining operations. Prairie Lithium is a valuable source that aligns
with our commitment to a secure a sustainable North American supply chain. This Agreement strengthens our ability to meet growing demand
while maintaining operational efficiency,” commented Pablo Cortegoso, Chief Technical Officer and Co-Founder of Stardust Power.
The
Prairie Project is situated in the Williston Basin of southeast Saskatchewan, Canada, a region renowned for its long history of oil and
gas production. The Project has been de-risked through the development of multiple well-pad sites and production of initial samples,
and it benefits from access to critical infrastructure, including electricity, fresh water, paved highways, and railroads, spanning approximately
350,000 acres of mineral rights.
“We
are proud to partner with Stardust Power to supply high-quality lithium feedstock for the U.S. market. It highlights the value of cooperation
between trusted strategic allies in securing a clean energy supply chain and demonstrates the strength of Prairie’s resources and
our commitment to supporting scalable, sustainable lithium production critical to North America’s energy security” said Paul
Lloyd, Managing Director of Prairie Lithium.
This
Agreement significantly strengthens Stardust Power’s commercial position, unlocking access to new financing avenues including project-level
debt and equity. It also represents a major de-risking step as the Company moves closer to full-scale construction and commissioning.
With permitting in the advanced stages, ground already broken at the Muskogee site, and an initial offtake Agreement signed, Stardust
Power is demonstrating strong operational execution and clear momentum. These milestones collectively underscore the Company’s
rapid progress from development to operations, reinforcing its ability to deliver key objectives and accelerate speed to market. Stardust
Power is well-positioned to capitalize on growing demand for domestic supply and refining of critical minerals, presenting a compelling
opportunity for long-term shareholder value creation.
