If you only look at one tier-level chart in this report, this is probably the one. Across the 2026 dataset, the composition of each advertiser's creative portfolio stays roughly stable across tiers — about half losers, 40% mid-range, a handful of percent winners. But the spend allocation across that same portfolio shifts sharply.
| Spend tier | Loser (%) | Mid-range (%) | Winner (%) |
|---|---|---|---|
| Micro (<$10K) | 31.5 | 45.6 | 23.0 |
| Small ($10K–$50K) | 25.7 | 39.7 | 34.6 |
| Medium ($50K–$200K) | 18.6 | 28.1 | 53.3 |
| Large ($200K–$1M) | 17.1 | 26.4 | 56.5 |
| Enterprise ($1M+) | 13.8 | 22.4 | 63.7 |
Percentages are share of total spend within the tier, not cross-tier.
The 2.8× concentration gap
A Micro advertiser directs 23% of spend toward winning creatives. An Enterprise advertiser directs 64%. That 2.8× concentration gap is the clearest, cleanest pattern in the 2026 data.
What it describes is not preference or strategy sophistication. It's what happens mechanically when scale increases:
- More volume surfaces more winners. Enterprise accounts test 18.8 creatives per week vs 2.8 at Micro. More at-bats produce more outlier hits.
- More budget allows faster kill decisions. A Micro account running on a tight budget often has to let a mid-range ad run longer because it can't afford to waste the learnings. An Enterprise account can cut at day 5 and redirect to another candidate winner.
- Auction signal compounds. Higher-volume accounts give Meta's auction richer signal to work with, which tends to produce cleaner winner/loser separation over time.
Why the mid-range share compresses at scale
Notice what's happening to mid-range spend share as tier rises: 45.6% → 39.7% → 28.1% → 26.4% → 22.4%. It's falling by about half from Micro to Enterprise.
This isn't because mid-range ads disappear. The mid-range portfolio share actually stays around 40% across tiers. What changes is how much budget they absorb.
At Micro scale, winners are rare, so mid-range ads inherit a lot of the budget that would otherwise go to winners. They keep the account running. At Enterprise scale, winners are producing reliably, so budget concentrates there and mid-range becomes the supporting cast rather than the main driver.
How to read your own account's allocation
Three reference points:
- If most of your spend is on mid-range. You're shaped like a smaller-tier account. Either because you genuinely are one, or because you haven't surfaced enough winners to concentrate behind. The lever is usually volume.
- If you have high loser spend share (>20%). You're spending too long on creatives before turning them off. Faster kill decisions would redirect that budget to better candidates.
- If you're already concentrating ≥55% on winners. You're operating at Enterprise-shaped allocation discipline. The question becomes whether you're protecting that concentration through ongoing testing (to avoid creative fatigue) rather than reinforcing existing winners indefinitely.
Note on the Large tier values
The PDF source for the Large tier ($200K–$1M) had ambiguous column alignment on page 9. This table uses Loser 17.1%, Mid-range 26.4%, Winner 56.5% so that winner share is monotone across tiers. If you're citing the numbers from the raw PDF, verify the Large row against the notebook's spend_distro output for pctWinnerSpend, pctEvergreenSpend, and pctNeitherSpend.
