Alphabet (GOOGL) shares opened September 30, 2026, near $344 and traded up roughly 2.5% intraday to the $349–$352 range, supported by broader technology-sector gains and positive AI-related sentiment, including company participation in a White House AI safety accord. The stock closed September 29 at $340.92 after a volatile September that saw a mid-month peak near $364 before profit-taking. Google Cloud revenue growth of 82% in the latest quarter, a substantial contract backlog, and strong overall margins continue to underpin fundamentals, though elevated capital spending and ongoing EU regulatory scrutiny remain watchpoints. Next quarterly results are scheduled for late October. Trader positioning for the September 30 close reflects these near-term catalysts and broader risk appetite.
