Yelp Inc, the operator of consumer review website Yelp.com, is exploring a sale that could fetch more than $3.5 billion, the Wall Street Journal reported, citing people familiar with the matter.
Yelp's shares rose as much as 16 percent on Thursday.

Yelp, which went public in 2012, had a market value of about $2.86 billion as of Wednesday, according to Thomson Reuters data.
The company, whose subscriber growth has been slowing in an increasingly competitive U.S. market, has been trying to expand in other markets and diversify into restaurant bookings, event management and payments.
A deal isn't imminent, the Journal cited one of the people as saying, and it's possible Yelp will decide against a sale.
Yelp declined to comment.
Suitors could include Google Inc, Yahoo Inc and even Microsoft Corp, FBN Securities analyst Shebly Seyrafi told Reuters.
This is not the first time rumors of Yelp being a takeover target have surfaced.
Speculations of Google, Yahoo and Priceline being possible suitors have done the rounds.
CNBC's Jim Cramer said in 2013 that Apple Inc should buy Yelp at $75 per share. (http://cnb.cx/1AI5Sy5)
