Our expert says

"Investing in emerging industries requires understanding that both outsized gains and losses are possible. Hype can cause stock prices to soar, while losses can mount if you buy in at peak excitement and the industry soon falls out of favor. Before investing, do your research and consider the legitimate potential of the new industry, taking a long-term view as you do. Consider exchange-traded funds (ETFs) to mitigate risk through diversification and gain exposure to all key players in the space."

Frequently asked questions

• What is the best graphene company?

  Several companies specialize directly in graphene production, which are listed on global stock exchanges. Some examples are:

  • HydroGraph Clean Power (HGRAF)
  • Graphene Manufacturing Group (GMGMF)
  • Black Swan Graphene (BSWGF)
  • NanoXplore (NNXPF)
  • Haydale (HAYD)

  It's worth looking at both US-based and foreign graphene companies to compare stock returns. Just remember that if you're interested in a specific non-US stock, check if it's available through your brokerage account.

• Are graphene stocks a good investment?

  Graphene stocks offer exposure to a still-emerging materials industry, but returns have been mixed and volatile — several of the stocks in the table above are down sharply in 2026. These investments carry real risks, including market volatility, thin trading volumes on some tickers, and companies shifting away from their original graphene business models, so thorough research and cautious position sizing are essential.

• Are Avadain and Real Graphene USA publicly traded?

  No. Avadain raises capital through equity crowdfunding (Regulation Crowdfunding and Reg A+ offerings filed with the SEC) rather than trading on a public exchange, so there's no ticker symbol or share price to buy.⁽¹⁰⁾ Real Graphene USA does not appear in SEC filings and has no confirmed public listing or ticker.⁽¹¹⁾ Neither company can currently be bought through a standard brokerage account.
