Futures for the S&P 500 and Nasdaq each fell 0.4% before the opening bell, while futures for the Dow Jones Industrial Average sank 0.6%.

Shares in Block, formerly known as Square, shot up more than 20% after markets closed following Dorsey’s comments about laying off about 4,000 of its 10,000 employees.

“We believe Block will be significantly more valuable as a smaller, faster, intelligence-native company. Everything we do from here is in service of that,” Dorsey wrote in a letter to shareholders.

Dorsey “just did what most CEOs have only whispered about in boardrooms,” Stephen Innes of SPI Asset Management wrote in a commentary.

“For years we’ve debated whether AI would dent jobs at the margin. Now we have a public case study where the CEO explicitly says intelligence tools have changed what it means to build and run a company,” he said.

Shares in streaming giant Netflix jumped 7.3% in premarket trading after it walked away from its bid to buy Warner Bros. Discovery’s studio and streaming business. That put Skydance-owned Paramount in a position to take over its Hollywood rival. Paramount Skydance shares climbed 7.9% before trading opened Friday.

Netflix said the price required to buy Warner after its board announced that Paramount’s offer was superior would make it a deal that is “no longer financially attractive.”

Warner Bros. shares fell 1.4% overnight. On Thursday, the entertainment giant reported a $252 million loss for the fourth quarter.

A peaceful solution would lessen the threat of war, which could disrupt the global flow of oil and drive prices higher.
