Amazon is in talks to buy podcast startup Wondery with a valuation of over $300 million, the Wall Street Journal reported on Wednesday citing people familiar with the matter.

Deal talks are ongoing and negotiations could still fall apart, the report said here.

Last month, Bloomberg News reported here that both Apple and Sony Music Entertainment have held talks about potentially buying Wondery, which is seeking $300 million to $400 million in a possible sale.

Amazon and Wondery did not immediately respond to Reuters requests for comment.
