Crypto entrepreneur Justin Sun has held talks about selling a stake in digital-asset exchange Huobi Global, according to a person with direct knowledge of the matter.

Sun has sounded out potential investors in past weeks, said the person, who asked not to be named discussing confidential information. It wasn’t clear what valuation the 32-year-old Chinese native is seeking for the company, or how big a stake is being offered. These conversations were in the early stages and it was not clear whether any of the investors might move forward, the person said.

“We are not seeking and will not seek any buyers for Huobi,” Sun said in a message. A spokesperson for Huobi said the company has no plans to seek a new owner. Sun has previously said he became an adviser to Huobi after amassing a large position in its native token, HT.
