Amazon has hit a $2 trillion market valuation, driven by a nearly 4% stock surge and significant investments in AI. The company's stock has risen 52% over the past year, with AI and cloud computing playing crucial roles in this growth. AWS is projected to reach $100 billion in annual revenue, aided by AI capabilities. Amazon has invested $4 billion in AI company Anthropic and is developing its AI chips. Amazon's revenue and profits have grown, bolstering investor confidence. Potential challenges, like an FTC antitrust lawsuit, are seen as distant concerns by investors.
