Good Morning!

The M&A hangover is officially here. If you thought the "synergies" slide in that pitch deck was just corporate speak, 4,000 folks at Omnicom would like a word. It’s a brutal reminder that in adtech math, 1 + 1 rarely equals 2—it usually equals 1.5 and a lot of severance packages.

Here are the 7 things you missed today:

The "efficiencies" have arrived. Following its acquisition of Interpublic Group, Omnicom announced today it is cutting approximately 4,000 roles. It’s the classic post-merger playbook: consolidate the back office, merge the media buying arms, and pray the clients don't notice the chaos. For the rest of the holding companies, this is the new baseline for "lean."

Forget "cloud computing"—AWS wants to build you an AI factory.

At re:Invent today, Amazon unveiled its new Trainium3 UltraServers and the "AI Factory" concept, allowing enterprises to deploy massive AI infrastructure inside their own data centers (managed by AWS, of course).

They're basically selling the shovels, the pickaxes, and the land for the AI gold rush.

If you're still reporting on ROAS based on who clicked last, you might as well be navigating with a sextant.

The integration of Nielsen segments into Amazon Ads (see below) highlights exactly why we need incrementality testing. When you can target based on actual TV viewing habits and shopping data, you realize that the "search" ad didn't drive the sale—it just took credit for the 30 impressions that happened beforehand.

Stop letting Google Search claim credit for the work your brand team did three months ago.

The walled gardens are getting a little window. Nielsen’s audience segments are now available directly in the Amazon Ads marketplace. This means you can finally target Amazon shoppers based on their verified media consumption outside of the Amazon ecosystem.

It’s a massive step for unified planning, and frankly, it’s about time Amazon let some third-party truth into their ecosystem.

Prediction markets aren't just for election betting anymore. Kalshi has raised a massive $1B Series E to scale its regulated exchange. Why does this matter to marketers? Because "sentiment analysis" is fluffy, but money on the line is real.

Expect to see brands using prediction markets to hedge against bad PR or gauge real consumer confidence faster than any focus group.

We might finally be free from the "Accept All" tyranny.

The European Commission is pushing a new "Cookie Pledge" initiative that would centralize consent in the browser, effectively killing those annoying pop-ups. It’s great for user experience but a potential nightmare for publishers relying on "consent fatigue" to get you to click yes. If this passes, your first-party data strategy just went from "important" to "existential."

If you’re looking for a low-lift, high-engagement format, this is it.

The "Our Version Of..." trend—where brands show their unique spin on common activities (e.g., "Our version of a coffee break" = chaos in the sample room)—is dominating feeds. It’s authentic, barely produced, and lets you show off company culture without the cringe of a scripted "About Us" video.
