Intercontinental Exchange Inc, owner of the New York Stock Exchange, has made an offer to buy eBay Inc in a deal that could value the ecommerce company at more than $30 billion.

Axar.az reports citing foreign media.

The companies aren't currently in formal talks and there is no guarantee eBay would agree to a deal, the report here said, citing people familiar with the matter.

EBay’s shares jumped 9.2% to $37.54, while ICE stock fell nearly 4% to $96.14 following the report.

ICE is primarily interested in eBay’s marketplace business, and not its classified unit, which eBay has been considering selling, the report said.

ICE declined to comment, while eBay did not immediately respond to Reuters’ request for comment on the WSJ report.

Earlier in the day, activist shareholder Starboard Value LP piled more pressure on eBay to sell the classifieds business, saying the company had not made enough progress to improve shareholder value.

“To achieve the optimal outcome, we believe Classifieds must be separated, and a more comprehensive and aggressive operating plan must be put in place to drive profitable growth in the core Marketplace business,” Starboard said in a letter to eBay’s board.
