Magnite jumps 5% as DOJ's Google ad tech ruling favors independent sell-side platforms

The U.S. Justice Department's antitrust ruling against Google has boosted supply-side ad tech stocks, with Magnite rising 5% and PubMatic up 6%. Craig-Hallum raised Magnite's price target to $32, citing the ruling's benefits for independent sell-side platforms competing with Google. The ruling requires Google to improve interoperability between its ad exchange and rival platforms, but demand-side companies like The Trade Desk saw little impact. Investors should watch for the final judgment in early October, which will finalize the details and enforcement of these remedies over six years.

As of Sep 17, 2026 21:27 WIB, PubMatic shares on Pluang have risen 4.75% to USD 17.65, reflecting strong investor interest following the antitrust ruling against Google. Meanwhile, The Trade Desk shows a slight decline of 0.21% at USD 14.46, indicating a more muted market response. Alphabet Inc Class A, Google's parent company, is up 1.18% to USD 346.90, with a market cap of $4.17 trillion, highlighting its dominant position despite regulatory challenges.
