  • The rumor was replicated by profiles with a blue paid badge, confusing users and the press.
  • The account “Walter Bloomberg” also spread the information, unrelated to the Bloomberg agency.
  • Reuters and CNBC reported it the alleged measure, but they deleted the posts minutes later.

According to Dow Jones Market Data, the global market lost $2,4 trillion in market value shortly after the rumor spread.

  • Declines in American and European stock markets
  • Abrupt swing in the dollar and commodities
  • Institutional investors were affected

The White House denied it officially the information still on Monday afternoon, but the damage was already done.

In 2023, the streamer Zealand did an experiment:

  • Created a player transfer rumor Ismaila Sarr to Everton.
  • Verified accounts spread the false information.
  • Betting sites have adjusted the odds in more than 300% in a few minutes.

"I was disturbed by how easy it was to manipulate the system.”, said Zealand, after seeing his test go viral globally.
