A few months ago, Silicon Valley’s leaders were sitting next to each other with wide smiles as Donald Trump was swearing. They were the ones who supported his election campaign and who visited him one after another at Mar -A -Lago. Today, however, just three months later, these people see their wallets empty rapidly due to the policies of the US president.

Companies established or run by its CEO of Meta, Mark Zuckerbergits chief executive Apple, Tim Cookits chief executive Google Sundar Pitsai, CEO of Tesla, Sun Mask and its founder Amazon, Jeff Bezoscumulatively lost almost $ 1.8 trillion in value since the beginning of this year, even after market recovery on Wednesday due to many planned duties. As a result, The personal property of these businessmen has shrunk, in accordance with Cnn.

All of them hoped to reap some business benefits from the election of Trump – such as fewer regulations or reduced antitrust pressure. Trump, for his part, was willing to expand the imprint of the US technology industry and to consolidate America as a leader in artificial intelligence. However, losses in Big Tech show that Silicon Valley will also face a series of new challenges In the wake of uncertainty about the US president’s tariff plans, which are largely targeting the supply chains in Asia, where technology companies supply components and assemble products.

Duties are an immediate challenge for technological giants and their financial impacts could also have negative consequences if consumers and advertisers tighten their wallet.

Analysts had warned that long -term mutual duties and the consequent financial uncertainty could shrink up to 25%technology, according to a UBS report on Sunday. This would mean a great shift from the relatively stable profits and prices of the shares enjoyed by Big Tech in recent years thanks to artificial intelligence.

On Monday, Wedbush Securities analyst Dan Avs described Trump’s tariff policy as a “Armageddon” for the technological sector, adding that “it makes the investment landscape in technology the hardest I have seen in the last 25 years.”

For ΄Ilon Mask The losses from Trump’s policies are huge. Despite the donation of at least $ 290 million to support Trump’s re -election and his participation in the Ministry of Government Efficiency, the wealthiest man’s fortune has fallen $ 143 billion since the beginning of 2025, according to Bloomberg Billionaires Index.

Tesla’s shares They fell 28% and its capitalization fell $ 376.6 billion since the beginning of this year, from the closure of the market on April 9, having largely deleted its post -election profits. Musk said the duties could have a “significant” impact on Tesla.

While Musk may be at the center of his proximity to Trump, he is not the only prominent technological personality that has seen his fortune significantly shrink.

Meta was one of the first big companies to promise to donate $ 1 million to Trump’s opening fund and Zuckerberg has repeatedly met with Trump, both before and after taking up his duties, to discuss policy priorities. Zuckerberg also made many Trump -friendly changes in his business, including the highlight of a prominent Republican to the company’s top policy position, the cutting of data control professionals and the addition of the Trump Allies and UFC head, Dana White to the Meta Board of Directors.

However, Zuckerberg’s net property decreased by 26.5 billion dollars since the beginning of 2025. Meta’s share price has fallen almost 2.25% since the beginning of the year to date, dragging the company’s valuation by $ 35.8 billion.

THE Jeff Bezos He hastened to congratulate Trump on his electoral victory in November, describing it as “excellent political return” and Amazon donated $ 1 million to Trump’s inaugural fund. Today, however, its net property has declined by $ 47.2 billion since the beginning of this year, according to Bloomberg. Amazon’s shares decreased by 13% from year to year, reducing the company’s total valuation by $ 316.8 billion since the beginning of this year.

OR Google donated $ 1 million At Trump’s opening fund and broadcast live the event on YouTube. And Pitsai participated in the parade of CEOs who visited the Mar- Lago in the weeks after the election. However, Google’s stock has now fallen by 16.2% and its valuation decreased by $ 386.7 billion since the beginning of this year.

THE Tim Cook He also donated $ 1 million to Trump’s inaugural fund, Axios said in January. Apple also gave Trump a political victory earlier this year, when it announced a $ 500 billion investment in US facilities over the next four years. Although some of these plans were likely to be in force before Trump’s duties were taken, the president claimed the credit for the movement, saying he showed “faith in what we do”.

However, Apple, which produces many of its gadgets in foreign markets such as China, Vietnam and India, is expected to be particularly hit by Trump’s duties. Its stock has dropped 18.5% since the beginning of this year and $ 684 billion has made wings from its stock market value.

During Trump’s first term, many large technology companies have been pressured for exemptions from Trump’s duties. This time, however, the situation is more uncertain, something that Moody’s Ratings have pointed out in a recent research note.

“Although it is difficult to appreciate the effects,” analysts wrote, “we believe that no sub -sector will be left untouched.”
