The Sun had suggested a £200 million takeover was on the cards
West Ham say there is no truth in a newspaper report that suggested drinks giant Red Bull wants to buy the club.
The Premier League side say they have had no contact from outside parties and co-owners David Sullivan and David Gold do not want to sell according to BBC and Sky Sports sources.
The initial story appeared in The Sun on St Stephen's Day.
The paper claimed that the Hammers were being considered for a £200 million (€235 million) bid from Red Bull.
Red Bull are involved in a number of football clubs around the world.
Major League Soccer side New York Red Bulls is owned by the drinks company, as well as Red Bull Salzbug in Austria.
In Germany, newly promoted high flyers RB Leipzig were founded by Red Bull in 2009 after taking control of fifth division side SSV Markranstädt.
Red Bull also run a lower division Brazilian side and until 2014 had a team in Ghana for six years.
They also own and operate the Red Bull Formula 1 team and its feeder team Toro Rosso.
