Imagine the ultimate tech showdown, where Microsoft and Apple jostle for the title of the world’s biggest company, not in a boxing ring, but on the stock market floor! Microsoft, riding the wave of AI enthusiasm, momentarily snagged the crown from Apple, with its market value peaking at USD2.87 trillion, thanks to its tight relationship with OpenAI and the frenzy around AI tech like ChatGPT. Apple, momentarily dethroned, didn’t let that sit for long, bouncing back to a market value of USD2.89 trillion by the day's end, despite some hiccups with iPhone sales and a less enthusiastic embrace of the AI hype train. This isn't the first time these two giants have traded punches; they've been at it since the '80s, with Apple once accusing Microsoft of mimicry, only to later lose the PC battle. Fast forward to the era of smartphones, and Apple managed to leap ahead, thanks to the iPhone. However, with AI on its side, Microsoft is proving to be a formidable contender yet again, hinting at an exciting next chapter in this decades-long rivalry. Meanwhile, Nvidia, an AI chipmaker, is quietly sneaking up on Amazon, proving that the tech world’s leaderboard is as dynamic as ever. And amidst this thrilling battle, both companies are eyeing the future, with Microsoft betting big on AI and Apple hoping its new Vision Pro headset will redefine computing once again.
