Roku Stock Surges 9% on Amazon CTV Advertising Partnership

Roku shares rallied sharply in pre-market trading after announcing a strategic advertising alliance with Amazon. The collaboration enables Amazon''s demand-side platform (DSP) to access Roku''s connected TV inventory, creating the largest verified CTV audience in the U.S. market.

Early tests demonstrate compelling efficiency gains - advertisers achieved 40% greater unique reach without budget increases while cutting ad repetition by nearly 30%. The deal effectively triples media value by combining Roku''s 80 million CTV households with Amazon''s Fire TV ecosystem.

This partnership arrives as streaming platforms aggressively monetize viewership through targeted advertising. Roku''s stock performance reflects growing investor confidence in its ability to compete against tech giants in the digital ad space.
