Apple Siri deal drives Google past historic trillion-dollar milestone: Big tech gets even bigger

On Monday, Apple announced a huge new deal with Google — the AI version of Siri will be powered by Google Gemini. Not long after, Google achieved something very few other Big Tech companies have.

Specifically, Google's parent company Alphabet became just the fourth company to hit a $4 trillion stock market valuation, following Nvidia, Apple, and Microsoft, per CNBC.

The other three companies all reached that threshold less than a year ago, so this is a recent phenomenon in the stock market. It should be noted that Apple and Microsoft are both back below the $4 trillion line, so Google could easily lose this honor at any time, for any reason.

So, how much money is four trillion dollars?

If you were to convert the $4 trillion into one dollar bills and stack them on a football field, the resulting pile would be about half a mile high, roughly equivalent to the Burj Khalifa in Dubai. If you were to simply stack one bill on top of the other, the resulting pile would reach far past the moon.

The news comes just hours after Google announced a multi-year collaboration with Apple that will make Google's Gemini AI model the backbone for Apple's future AI efforts. As CNBC noted, Alphabet's shares went up by about 1 percent after the news dropped, so it seems like that was more of a "the fly that broke the camel's back" situation than something monumental that got Alphabet to $4 trillion by itself.

Anyway, between Google's continued search dominance and its growing AI and hardware businesses, it seems like Alphabet is doing just fine.
