Investing in public graphene stocks
Graphene is a one-atom-thick sheet of carbon atoms arranged in a honeycomb (hexagons or chicken-wire) crystal lattice. Graphene is the world's strongest and most conductive material, and no wonder that researchers and professionals looked into graphene's potential across many applications, including sensors, batteries, conductors, displays, electronics, energy generation, medicine and more.
The commercialization of graphene is just in its infancy, but already dozens of new companies have been established to develop graphene based materials, applications, graphene production processes and other related activities.
There are many companies directly involved with graphene. Most of these companies are either private early stage companies or large companies in which graphene is just one business segment, but some pure-play graphene companies are public. Below we will list some potential graphene stocks for investors that wish to take part in the graphene revolution. For a more in-depth analysis of the possibility of investing in graphene, and a complete public companies listing, see our Graphene Investment Guide.
Pure-play graphene companies
In the past few years several graphene producers and graphene application developers started trading in stock exchanges around the world - mostly in Australia, Canada and the UK. Here we'll list some of those companies:
Versarien (AIM:VRS) is an advanced materials group leveraging proprietary technology to create innovative engineering solutions for its clients in a diverse range of industries - focusing on graphene materials.
Haydale (AIM:HAYD) is a UK-based supplier of functionalized graphene and related technologies. Haydale is mostly involved with graphene composite solutions and graphene-based inks. In 2016 Haydale acquired ACMC, a US-based silicon carbide whisker manufacturer.
G6 Materials (TSX: GGG), formerly known as Graphene 3D Lab, focuses on development of high-performance graphene-enhanced materials.
Other graphene investment options
Several large and public companies (such as Samsung, Intel, Nokia, IBM and Sony) are involved in graphene research. These companies may be on the forefront of graphene research - especially in high-end fields such as electronics and photonics - but graphene, even if successful, will probably represent a small portion of their business.
Another option is to invest in graphene production equipment. Aixtron SE, for example, is a provider of deposition equipment to the semiconductor industry who offers CVD graphene production systems. Aixtron trades in the NASDAQ (ticker:AIXG). US-based CVD Equipment Corporation also offers graphene R&D and production equipment. CVD Equipment trades in the NASDAQ (ticker: CVV).

Haydale announces key certification for US and Canada
Haydale has provided a trading update highlighting the recent commercial progress of its JustHeat product line: a low-power, graphene-based heating system. According to Haydale, the product has now received UL certification, a critical regulatory milestone that enables the commercial sale of the JustHeat system in the US and Canada.
It was reported that there is "strong demand" in the UK for JustHeat from social landlords. To date, Haydale says it has secured commitments for over 40 pilot installations across Welsh housing providers.
GMG moves toward new 10-tonne graphene plant
Graphene Manufacturing Group (GMG) has announced that it will invest AU$900,000 (around US$578,400) ahead of commissioning a planned 10 tonne per annum graphene plant, supported by a recent capital raise. According to a statement from GMG, the board’s approval for the investment will support early works for the expected plant, to be built at the company’s existing gas-to-graphene production site at Richlands, Brisbane.
The early works expenditure was “largely included” in the proposed use of proceeds for the aforementioned financing. At the time it also said net proceeds would cover R&D on its Graphene Aluminium-Ion Battery, sales efforts, working capital, and preparations to list on “a major United States exchange”.
Solidion reports its financial results for Q1 2025, with a $3.1 million operational loss
Solidion Technology, an advanced silicon anode and battery technology materials provider, announced its financial results for the Q1 2025. The company has no revenues, and it has lost $3.1 million from its operations.
Solidion also updated that it has recently secured US patents for a proprietary technology that enables the conversion of existing lithium-ion manufacturing facilities to produce solid-state batteries through in situ solidification. The company recently announced that its Li-S batteries have achieved a cell energy density of 380 Wh/kg, with a near-term target of 450 Wh/kg.
Archer Materials enters partnership with Paragraf for Biochip development
Archer Materials, a semiconductor company advancing the quantum technology and medical diagnostics industries, has signed an agreement with UK graphene-based electronics company Paragraf to advance development of Archer’s Biochip potassium ion sensor for testing of chronic kidney disease.
The agreement will be in two stages, with each stage of work to be carried out over three months at a total estimated cost of AU$450,000 or £222,000.
The partnership will accelerate technical progress towards meeting the blood potassium sensing target product profile (TPP) using a gFET. Work performed by Paragraf with Archer will complement the activities ongoing in Sydney.
