Best Penny Stocks Under 25 Cents
Prairie Lithium Ltd (OTC: AZLAF)
Overview
Prairie Lithium Ltd focuses on developing lithium projects in North America, mainly the Prairie project in Saskatchewan and the Lordsburg project in New Mexico.
Both lie in mining-friendly areas with access to infrastructure and supportive local policies for critical mineral production.
The company has been advancing Direct Lithium Extraction (DLE) technology, a cleaner and faster process than traditional methods, aiming to reduce environmental impact and improve recovery efficiency.
Its recent rebranding to Prairie Lithium Limited highlights a stronger emphasis on the Canadian project as it moves toward commercial validation.
Growth Catalysts
Global demand for lithium continues to surge as electric-vehicle and energy-storage industries expand.
Arizona Lithium is well-positioned within this trend, benefiting from the North American push to secure domestic battery-metal supply chains.
The Prairie Project’s brine resource offers scalability, while its pilot program could validate the DLE process and attract strategic partnerships.
Meanwhile, the Big Sandy site provides exposure to the growing U.S. battery corridor, potentially aligning the company with automakers seeking local lithium sources.
Conclusion
This is an early-stage, high-risk play in the lithium supply chain, but one with promising upside.
If the company can prove its DLE technology at scale and maintain disciplined development, it could evolve from explorer to producer within a strengthening market.
Execution will remain the deciding factor for long-term success.

InnerScope Hearing Technologies, Inc. (OTC: INND)
Overview
InnerScope Hearing Technologies develops affordable over-the-counter hearing aids and personal sound devices for consumers who want hearing solutions without a prescription or clinic visit.
It operates in the rapidly expanding direct-to-consumer hearing health market made possible by the FDA’s rule change that legalized over-the-counter hearing aids.
The company sells through its website and online marketplaces, offering rechargeable and Bluetooth-enabled models designed to make hearing improvement more accessible.
Growth Catalysts
Hearing loss affects tens of millions of Americans, yet many avoid treatment due to cost and stigma. InnerScope’s approach targets that gap by combining affordability with convenience.
The over-the-counter category is still young, and early movers have room to build strong brand awareness.
InnerScope is also developing digital hearing-assessment tools and subscription-based product services, aiming for recurring revenue.
As awareness grows and baby boomers continue aging into their seventies, the company’s addressable market will likely expand significantly over the next several years.
Conclusion
The business operates in a promising but competitive segment that includes both startups and large consumer-electronics companies.
While execution and marketing remain crucial, InnerScope represents a speculative yet timely play on hearing accessibility in the U.S.
If it can sustain brand growth and manage production efficiently, it could carve out a durable niche in this newly deregulated market.
SunHydrogen, Inc. (OTC: HYSR)
Overview
SunHydrogen is a clean-tech company working to transform the way hydrogen is produced.
Rather than relying on traditional steam-methane or heavy-industrial processes, it uses a solar-powered “panel” system that directly splits water into hydrogen using sunlight and proprietary catalysts.
The idea is to eventually manufacture modular units that can be deployed at scale and produce green hydrogen with minimal fossil fuel input.
The company formerly operated under a different name and has pivoted cleanly into this niche, positioning itself for a future where hydrogen is a major part of the global energy transition.
Growth Catalysts
The global hydrogen economy is expected to expand significantly over the coming decade as governments and industries aim to decarbonize.
SunHydrogen’s technology, which seeks to mimic photosynthesis and produce hydrogen from water and sunlight, taps directly into that trend.
Recently, the company showcased a larger-scale panel prototype and entered a pilot collaboration with a major university and partner to explore commercial deployment.
Because hydrogen can serve in transportation, energy storage, and industrial uses, the addressable market is broad.
If SunHydrogen’s panels prove cost-competitive with existing methods and scalable, they could attract strategic partnerships or become a component supplier to major manufacturers.
Conclusion
This is a high-speculation play with all the upside and all the risk that implies. The technology is at an early stage, and commercialization remains a big hurdle.
For an investor comfortable with highly speculative ventures and the patience to wait, SunHydrogen offers exposure to a possibly disruptive green-hydrogen technology.
But those benefits won’t come without execution, funding, and scale-up success.
Cyberlux Corp (OTCMKTS: CYBL)
Overview
Cyberlux Corp designs and delivers technology solutions for defense, security, and industrial clients.
Originally known for portable LED systems used by the U.S. military, the company has evolved into new areas such as drone technologies and tactical communication systems.
Its goal is to supply modern, lightweight, and energy-efficient products that enhance operational capabilities in both defense and commercial environments.
Growth Catalysts
Rising defense budgets and the growing role of drone technologies in national security offer an opportunity for nimble innovators.
Cyberlux is working to expand its footprint within this ecosystem by integrating its lighting and surveillance systems into drone-based applications.
The company’s efforts to develop partnerships and expand government contracts could transform it from a niche equipment provider into a broader defense-technology participant.
Additionally, its history with energy-efficient lighting gives it potential crossover opportunities in commercial and industrial markets that need sustainable, durable lighting systems.
Conclusion
This remains a microcap defense-tech story with a speculative profile, but the company’s transition toward drone integration adds modern relevance.
Success will depend on execution, government contracting wins, and technology validation.
For risk-tolerant investors, Cyberlux provides exposure to an evolving defense segment that continues to attract global attention.
Harrison Global Holdings Inc (NASDAQ: BLMZ)
Overview
Harrison Global Holdings, formerly Bloomz Inc, operates as a digital marketing and technology company that’s shifting toward AI-driven advertising solutions.
Its platform aims to help small and mid-sized businesses use artificial intelligence and analytics to improve customer engagement, automate campaigns, and maximize ad performance.
The firm’s listing on the Nasdaq provides it with a higher degree of transparency and access to capital compared to most microcaps.
Growth Catalysts
The rise of AI-powered marketing tools has changed how businesses approach customer acquisition and retention.
Harrison Global is positioning itself to serve smaller enterprises that can’t afford complex enterprise-level solutions.
By focusing on intuitive software and automation, it could benefit from the growing demand for simple, data-driven marketing tools.
Its ongoing product refinements and potential partnerships with e-commerce or social platforms could expand its visibility.
The company’s pivot from its earlier social-networking model to AI-driven marketing also reflects its adaptability in a fast-changing digital landscape.
Conclusion
Harrison Global sits at the intersection of AI and digital advertising, a space with vast long-term potential but significant competition.
Its challenge will be scaling adoption and proving that its platform can deliver measurable results.
For speculative investors, it offers an intriguing glimpse into how small tech firms are trying to carve their own path in the AI transformation wave.

Should You Buy Penny Stocks Under 25 Cents?
Penny stocks under 25 cents could be a good option for folks with a high risk tolerance.
However, penny stocks do come with their own set of challenges.
Transparency is one of the key issues with penny stocks. Many of these companies are not required to offer the same level of transparency in their financial disclosures.
This makes it much harder to gauge the performance of a company. Another challenge with penny stocks is that many are illiquid. As a result, traders may struggle to exit a position.
These are just some of the pitfalls of trading stocks under $5.
Where to Buy Cheap Penny Stocks
Robinhood is one of the most famous brokerages offering commission-free trading. If you want to buy cheap penny stocks without paying commissions, Robinhood is a reliable brokerage and a quality choice.
Another good option is Fidelity. It doesn’t offer commission-free trading like Robinhood — but at just $4.95 per trade, Fidelity is an affordable option if you don’t mind paying a small fee.
Since not all the stocks listed above appear in major exchanges, Fidelity supports OTC stocks, so you can buy and sell penny stocks that are not listed in either NASDAQ or NYSE.

Major Risks in Penny Stocks Under $0.25
Investing in ultra-cheap equities requires accepting significant uncertainty. The main challenge is liquidity, as even modest buy or sell orders can move prices sharply.
Many of these companies also rely on frequent share issuances to raise capital, which dilutes existing shareholders.
Delisting risk is another concern. Exchanges like Nasdaq require minimum price and reporting standards, and falling below them can push a company to the OTC markets where regulation is lighter.
Once there, information can be sparse, making due diligence harder.
Information quality also varies. While some microcaps maintain audited financials, others publish limited disclosures. Investors should read filings carefully, verify management backgrounds, and understand that not every “low price” equals “undervalued.”
Psychologically, these stocks can feel like lottery tickets, tempting investors to over-allocate or ignore losses. The smartest approach is to treat them as speculative side bets, interesting stories rather than core portfolio holdings.
Final Thoughts
Penny stocks under 25 cents exist on the outer edges of the market, volatile, often overlooked, but occasionally rewarding.
The five names here represent different corners of innovation: critical minerals, hearing health, sustainable materials, defense technology, and AI marketing. Each company has a story built around real trends shaping the U.S. economy.
Still, it’s crucial to remember that these trades demand caution. Due diligence, patience, and proper risk sizing are essential.
These are speculative tickets into emerging ideas, not guaranteed paths to wealth.
For folks who understand that reality and are willing to navigate the turbulence, 2025 offers no shortage of stories where a single quarter could buy a share, and maybe, just maybe, a small piece of the next breakout.
