As the end of 2023 approaches, industry professionals in the domain name sector have analyzed the sales performance of four non-.com top-level domains. Here are some key insights:

1. For the first time, .ai achieved the highest return on investment, reaching an impressive 8.39%, followed by .io at 6.80%.
2. These data somewhat favor domain names with single common words, as they are commonly used in daily life and constitute a significant portion of non-.com domain extensions.
3. Investments in non-.com domain names carry speculative elements, and the trends in return on investment may vary significantly. For example, .xyz had a much higher return on investment in 2021, but in 2023, its return on investment is 3.10%, ranking third from the bottom.
4. Venturing beyond strong vocabulary in these extensions may result in a significant decrease in return on investment. Therefore, choosing names with a clear purpose aligned with industry trends is crucial in these extensions.
Below are the top 10 transaction amounts for .ai, .co, .io, and .xyz compiled from the NameBio website.

These are the top 10 transaction rankings for the four new top-level domains as of 2023. It's worth noting that .ai domains have shown outstanding performance, particularly after the release of ChatGPT, quickly gaining prominence. Currently, there are very few .ai domains available for purchase, including "Robot.ai," "Trader.ai," "Fund.ai," "Y.ai," and others that are still on sale. If you are interested in .ai domains, it is strongly recommended to consider seizing the opportunity.
