Magnite is trading 4.4% down today at $19.03 as part of a broader tech and AI-related sell-off hitting U.S. markets.
- The move follows a wider market retreat, with the Nasdaq and S&P 500 both sliding more than 1%.
- With no fresh company-specific earnings or news today, the decline appears driven by sector-wide pressure and profit-taking in volatile ad-tech and growth names.
