Alphabet shares closed near $343.50 on October 2 amid a recent Gemini 4 Argon launch that bolstered perceptions of competitive AI positioning against OpenAI and Anthropic. Google Cloud revenue surged 82% year-over-year in Q2 to $24.8 billion with a $514 billion backlog, supporting trader optimism, though elevated 2026 capex guidance of $195–205 billion pressured free cash flow and contributed to the stock trading 16% below its May high. With Q3 results due October 28 and no immediate catalysts in the Oct 5 week, market-implied odds cluster around the $335–355 range, reflecting balanced views on near-term momentum versus infrastructure spending and broader tech sentiment.
