The technology sector jumped about 3%, powered by a 10.6% jump in Intel shares (INTC) after U.S. President Donald Trump said that Apple Inc. (AAPL) had agreed to use Intel’s foundry services. The development marks a major win for the government-backed chipmaker and appears to confirm months of deal speculation.

Robert Conzo, chief executive officer at The Wealth Alliance, told CNBC in an interview that he believes there’s “more bullishness around companies working together because of [artificial intelligence] infrastructure and the effects of AI within many, many different competing industries.” He also said, “I think Apple-Intel was a little proxy for what you could see happening in the future.” 

Oil prices also dipped, with Brent and WTI futures trading below $80 per barrel, supported by a US-Iran peace deal.

Donald Trump and Iranian President Masoud Pezeshkian signed a preliminary agreement on Wednesday in a bid to end the conflict between the two countries and reopen the Strait of Hormuz, a move that could increase global oil supplies.

As part of the deal, the U.S. will begin lifting its naval blockade of Iran and restore pre-war military deployments within 30 days. Iran, in turn, will facilitate the reopening of the Strait of Hormuz, allowing commercial shipping to resume without transit fees. The deal outlined a 60-day negotiation period, which can be extended, to finalize a broader settlement. 

However, according to a BBC report, U.S. Defense Secretary Pete Hegseth said Washington remains prepared to “reimpose an ironclad blockade” and other measures if Iran fails to comply with the terms of the agreement.
