Crypto tokens linked to artificial intelligence have seen a surge in interest after reports that Microsoft could invest $10 billion into ChatGPT creator OpenAI.

The rally has cooled slightly since news of the deal first broke last week, but nine coins connected to the sector have surged over 50% in the past week, according to CoinGecko. Many of the tokens are considered “small cap” with low liquidity, meaning it doesn’t take much to move the price.

ImgnAI, a token linked to an anime-based AI image generator, has been one of the top performers, rising a whopping 718% over the past week. The coin has seen transaction volume of $750,198 in the past 24 hours. Fetch.ai, a more liquid AI-related coin, saw volume of $77.6 million over the past 24 hours. It's up 65.1% over the past week.
