Apple slid more than 6% in late trading Wednesday and led a broader decline in tech stocks after President Donald Trump announced new tariffs of between 10% and 49% on imported goods.

The majority of Apple’s revenue comes from devices manufactured primarily in China and a handful of other Asian countries. Nvidia, which manufactures new chips in Taiwan and assembles its artificial intelligence systems in Mexico and elsewhere, fell about 4%, while electric vehicle company Tesla dropped 4.5%.

Across the rest of the megacap universe, Alphabet, Amazon and Meta all dropped between 2.5% and 5%, and Microsoft was down by almost 2%.

If Apple’s postmarket loss is matched in regular trading Thursday, it would be the steepest decline for the stock since September 2020.

Trump on Wednesday afternoon said the new taxes on imported goods would be a “declaration of economic independence” for the country. He announced a 10% blanket tariff on all imports, and higher duties for specific countries, including 34% for China, 20% for European nations, and 24% for Japanese imports, based on what tariffs they charge on U.S. exports, Trump said.

“We will supercharge our domestic industrial base, we will pry open foreign markets and break down foreign trade barriers,” Trump said during his speech. “Ultimately, more production at home will mean stronger competition and lower prices for consumers.”

Stocks broadly got hit by Trump’s announcements. An exchange-traded fund tracking the S&P 500 slid 2.8%, while an ETF following the Nasdaq 100 lost more than 3%.

During his speech, Trump praised Apple, Meta, and Nvidia for spending money and investing in the United States.

“Apple is going to spend $500 billion, they never spent money like that here,” Trump said. “They’re going to build their plants here.”

The Nasdaq just wrapped up its worst quarter since 2022, dropping 10% in the first three months of the year, though the tech-heavy index rose in each of the first two days of the second quarter.

Amazon submitted a bid to the White House to purchase the social media app TikTok from its Chinese owners, CNBC has confirmed.

The company sent its proposal in a letter this week to Vice President JD Vance and Commerce Secretary Howard Lutnick, according to a source familiar with the matter who asked not to be named because the discussions are confidential. The parties aren’t treating the bid seriously, however, given that it was submitted just days before a deadline staving off a U.S. ban is set to expire, the person said.

Amazon declined to comment.

The e-commerce company’s offer, which was first reported by The New York Times, comes as TikTok’s fate in the U.S. is up in the air. The short-form video app faces another potential shutdown in the U.S. on April 5 if ByteDance, its parent company, can’t reach a deal to divest TikTok’s American operations. Lawmakers passed a bill last year setting a Jan. 19 deadline for the sale, but Trump signed an executive order granting a 75-day extension for a potential deal.

Trump could announce a decision on TikTok’s fate in the U.S. as soon as Wednesday, sources familiar with the situation told CNBC’s David Faber. Mobile technology company AppLovin has also made a bid for TikTok, Faber reported separately, citing sources familiar with the matter.

TikTok has emerged as a major hub for e-commerce as it has poured money into growing its online marketplace, called TikTok Shop. TikTok’s lucrative marketplace, coupled with the app’s more than 170 million users, could be an attractive asset for Amazon. Following TikTok’s success, Amazon launched and then shuttered a short-form video service of its own.

Last August, the two companies formed a partnership that allowed TikTok users to link their account with Amazon and make purchases from the site without leaving the app. The deal attracted scrutiny from lawmakers who were concerned about its potential national security risks.

Tesla shares rose Wednesday after Politico reported that Elon Musk could leave his post at the so-called Department of Government Efficiency, paving the way for the CEO to return his focus on the struggling EV maker.

The White House later called the report “garbage.”

The stock was last up about 5%. At its session lows, it had dropped as much as 6.4% on the back of weaker-than-expected vehicle deliveries for the first quarter.

The report — which cites Trump insiders — noted that, while President Donald Trump is pleased with Musk and the DOGE spending cuts that have been pushed through, the two decided in recent days that the billionaire would soon return to his businesses. NBC News is reporting that Trump told the cabinet Musk could leave in the coming months.

Wednesday’s report comes during a tough stretch for Tesla. Despite Wednesday’s gains, the stock has dropped more than 5% over the past month. Year to date, it has tumbled more than 31%. Shares also shed 36% in the first quarter, marking their biggest quarterly drop since 2022.

Musk’s role in the White House is one factor weighing on Tesla’s stock. It has sparked waves of protests, boycotts and violent attacks on Tesla stores and vehicles around the world. Trump’s automotive tariffs are also a concern as they involve Tesla’s key suppliers — notably in Mexico and China.

“My Tesla stock and the stock of everyone who holds Tesla has gone, went roughly in half,” Musk said on Sunday night at a rally he held in Green Bay, Wisconsin, to promote a Republican judge he backed in Tuesday’s state supreme court election, Brad Schimel. “This is a very expensive job is what I’m saying.”

In addition to holding the rally in Wisconsin, Musk spent millions and frequently posted about the race on his social network X. Judge Susan Crawford, who won the seat on the Wisconsin Supreme Court, was backed by Democrats and progressive groups who criticized Musk, his money and influence on the race as well as his DOGE work in their campaigns.

Separately, New York City Comptroller Brad Lander urged the city to sue Tesla on behalf of NYC pension funds citing Musk’s work for the White House.

In a Tuesday statement, Lander’s office said: “The basis of the potential litigation are the material misstatements from Tesla claiming that CEO Elon Musk spends significant time on the company and is highly active in its management, despite his helming the Trump Administration’s DOGE initiative, spending little of his time actually managing Tesla, and promoting policies that are actively harmful to Tesla’s business.”

CNBC reached out to the White House for comment.
