When the Auction Moves Overnight: Media Buying in a Temu/Shein Market

In this episode of Shift Happens, host Nasser Sahlool is joined by Felicia Delvecchio, Vice President of Media at DAC, to explore how fast-moving advertisers like Temu and Shein are reshaping media auctions in 2026 — not just through scale, but through the speed at which they ramp spend up or pull it back. 

They unpack why today’s challenge is less about permanently rising media costs and more about volatility, how that pressure shows up first in high-intent channels like search, shopping, and social, and why marketers can no longer rely on static annual plans or top-line reporting. The core message: success in 2026 depends on disciplined, panic-free decision-making, granular market visibility, and agile “if-then” playbooks that help brands respond to shifting auction dynamics without overcorrecting.
