The Nasdaq Composite rose 0.82% to 26,169 on Oct. 26, 2026, driven by renewed optimism in the artificial intelligence sector following the initial public offering filing by Anthropic. The S&P 500 gained 0.70% to 7,677, while the Dow Jones Industrial Average edged up 0.28% to 52,362, marking a divergence from the previous day's energy-focused trading as oil prices retreated.
Anthropic, which filed its S-1 prospectus to list on the Nasdaq under the ticker "ANT," provided the catalyst for the tech rally.
