Amazon reported a 17% increase in Q1 revenue, reaching $181.5 billion, surpassing Wall Street's expectation of $177.3 billion. Earnings per share (EPS) were $2.78, exceeding forecasts of $1.64, driven by a $16.8 billion pre-tax gain from its investment in Anthropic. Excluding this gain, adjusted EPS was $1.61, slightly below expectations. AWS revenue grew 28% to $37.59 billion, marking its fastest growth in 15 quarters. CEO Andy Jassy highlighted that Amazon's in-house chip business has surpassed $20 billion in annualized revenue, with significant growth in AI chip deployment. Despite strong revenue, Amazon's stock fell over 3% in after-hours trading. The company provided Q2 revenue guidance of $194 to $199 billion, above analyst expectations, and announced Prime Day will be moved to June.
