Marketers trust fewer channels than they think, and this concentration of trust determines where budgets go.
This is one of the clearest signals from the Haus 2026 Decision Trust Index. When looking at how marketers measure performance today, trust is not evenly distributed. It’s concentrated. And that focus is starting to dictate investment decisions in a way that should sound familiar to anyone who has participated in a budget review with finance.
Confidence in metrics is a marketer’s ability to clearly explain and defend a channel’s impact on revenue.
If you ask marketers which channels they can confidently champion from a measurement and ROI perspective, the list is surprisingly short. Google Search and YouTube came out on top, each with 57% of respondents feeling confident in defending these investments. When combined, that jumps to 75%.
After that, there is a noticeable drop. TikTok and Meta are in the low to mid 40% range, and everything else falls further behind. Even more significant are influencer partnerships, brand activations and newer formats like connected TV.
It’s not just a ranking. This reflects a structural shift in how marketers evaluate channels.
Marketers don’t just choose channels based on performance. They choose based on how well they perform in a room where someone asks, “Can you prove this worked?” The more confident you are in the answer, the more secure the budget seems.
And right now, that trust is concentrated around a small set of established platforms.
Budgets track channels marketers can champion
The concentration of trust does not remain theoretical for long. This appears directly in the investment plans.
The channels that marketers believe they are most confident in defending are those expected to see the biggest budget increases in 2026. Google Search leads the pack, with around 80% of respondents expecting increased investment. YouTube follows at 72%, followed closely by Meta at 71%.
The pattern is hard to miss. Trust → defensibility → investment.
There is a practical reason for this. In an environment where monitoring is rigorous and measurement is becoming increasingly difficult, marketers are under pressure to justify every dollar spent. The easiest channels to explain win by default.
This does not necessarily mean that they are always the most effective. This means they are the easiest to defend.

Budgets are concentrated in a comfort zone of measurement
This concentration of confidence creates a comfort zone of measurement. Budgets are routed through channels where attribution is clearer, historical performance is well understood, and internal stakeholders feel confident to approve.
Everything else is outside this zone.
This includes channels that marketers are actively interested in. YouTube and TikTok rank high in terms of future exploration, along with influencer partnerships and podcasts. There is curiosity and an intention to experiment, but this intention does not always translate into immediate budget changes.
For what? Because exploration is harder to defend than optimization.
It’s one thing to say, “We’re increasing spending on paid search because we know it works.” » It’s another to say, “We’re testing a newer channel where the metrics are less clear.” » One of these conversations happens much more easily during a financial review.
So even as marketers look for growth in new formats, they still anchor their spending in channels they can explain.
Confidence in measurements becomes strategy
The takeaway here is not that marketers should only invest in Google and YouTube. This is because confidence in measurements becomes the main driver of strategy.
If a channel is performing well but cannot be clearly defended, it is in danger. If a channel is easy to defend, it is more likely to grow, even if its progressive impact is more difficult to isolate.
This dynamic will shape the way media plans are constructed over the coming years. This also raises a larger question: are we optimizing for performance or for defensibility?
Because right now, those two things aren’t always the same.
And until marketers close this gap, budgets will continue to focus where they seem safest to explain, not necessarily those with the most benefit.
Key takeaways
- Marketers trust a small set of channels, led by Google Search and YouTube.
- Budget increases focus on channels that marketers can most easily defend.
- Confidence in metrics influences investment decisions as much as performance.
- Newer and emerging channels face slower adoption because they are harder to justify.
- Marketing strategy is increasingly focused on defensibility, not just effectiveness.
