After heavy losses in share prices in US stock markets on Wednesday, there is no other technology -related companies who have beaten late.
From the concerns of AI profitability, from the tariff to the supply of chains to the political uncertainty on everything and a comprehensive conversation on whether the evaluation in any case had become very high, many of the world’s largest companies such as Tesla and NVDia have already seen their evaluation in 2025.
It has also been a case for broad markets, in the negative area for the year so far with both Nasdac Composite and S&P 500.
And as a result, important shareholders of those companies have lost in turn that most of us will consider a full fate – with the top ten US -based technology owners this year looking at their value by a combined $ 217BN (£ 168bn) so far this year.

Of the ten, only two are so far in green for 2025, while one, Tesla’s chief Elon Musk has lost $ 113BN (£ 87bn) even after Tesla’s back of Tesla in Wednesday’s business in Wednesday’s trading.
It includes Mr. Musk to lose $ 29bn (£ 22bn) on Monday, as the shares declined rapidly, while Benzinga reported that the top ten owners lost a joint $ 67BN (£ 51.7bn) that day, because a group of companies known as those companies is known as about 780BN (£ 602BN).
Bloomberg Billionaire Index (BBI) tracks the fate of the richest people on the planet on a daily basis, with a significant part of their value based on the stock market prices of companies established by them, they work or invest for – and in many cases, all three.
Despite the decline in Shri Musk’s year over the year, he lives on top of the pile with a total assets of $ 319BN (£ 246bn)-some $ 100BN of Amazon founder Jeff Bezos clear, which ranks second.
Mr. Bezos has lost $ 19.3BN this year, while Google’s co-founder Larry Page and Sergei Brin are below $ 17.5BN and $ 16.4bn respectively.
