Apple Inc. has surged to a record valuation of $3.3 trillion, overtaking Microsoft to become the world's most valuable company. This significant rise in market capitalization, which saw Apple add approximately $300 billion in just two days, is largely attributed to its recent focus on artificial intelligence (AI). The company's shares rose by over 12%, including a 2.5% increase, following announcements at the Worldwide Developers Conference (WWDC), where Apple unveiled new AI features expected to boost iPhone sales. This marks Apple's return to the top spot for the first time since January, driven by investor enthusiasm, a robust buyback program, and a Nasdaq record high amid signs of cooling inflation.
