Amazon's share price closed the week of September 28, 2026, near $248–$250 after fluctuating between intraday lows of $244.73 and highs near $252.44 amid mixed daily moves. Primary drivers included sustained AWS momentum, with Q2 revenue growth accelerating to 37% year-over-year on AI infrastructure demand and a $220 billion 2026 capex plan showing early returns through triple-digit growth in AI and chip segments. Broader tech sector rotation and profit-taking from September highs near $258–$267 weighed on sentiment, while Q3 guidance of $197–202 billion in net sales and upcoming October 28 earnings release remain key near-term catalysts. Trader positioning reflects ongoing debate over whether AI investment returns will sustain valuation multiples near 20 times forward earnings amid elevated capital spending.
