Ad Tech Stocks Rebound Over 5% Amid Earnings Report

Shares of Nasdaq-listed ad tech firm The Trade Desk Inc. (TTD) surged 5.49% today, closing at $22.45. Volume climbed to 13.86 million shares, and market capitalization increased by about $564 million to roughly $9.7 billion (approximately ₩13.6 trillion).

The stock had recently plunged double digits after Publicis, one of the world’s top three advertising groups, labeled The Trade Desk an “unrecommended” demand-side platform (DSP) for clients amid fee and billing transparency concerns. Omnicom has also initiated a separate audit, prolonging tensions with agencies. Earlier this month, CEO Jeff Green purchased approximately $148 million (around ₩210 billion) in company stock, and reports of ad partnership negotiations with OpenAI fueled a short-term rebound.

Founded in 2009 by Jeff Green, The Trade Desk provides advertisers and agencies with a platform to buy ads in real time across web, mobile, and connected TV channels. By 2025, annual revenue had grown to about $2.9 billion (near ₩4 trillion). Yet conflicts of interest with big tech firms and leading ad agencies, alongside questions over fee transparency, have emerged as key factors that could shape its future growth trajectory and valuation as it expands its AI-powered platform, Kokai.
