NVIDIA shares advanced more than 2% intraday on September 28, 2026, to trade near $230 after the company authorized an additional $150 billion in share repurchases, expanding the remaining program to a record $235 billion through fiscal 2028. The announcement, the largest buyback expansion in U.S. corporate history, underscored robust free-cash-flow generation from AI-driven data-center demand while providing direct support for the share price amid a broader Nasdaq decline. Recent quarterly results showed data-center revenue exceeding $89 billion with 117% year-over-year growth, though supply constraints and elevated valuations remain key variables. Traders are monitoring closing levels against recent highs near $236 and the prior session close of $225.07, with no major economic releases or company events scheduled before the bell.
