Q2 2026 hardware category preview, what to watch after the Q1 cracks

Three months ago we ran the Q1 tools teardown and flagged three patterns: top-10 concentration cracking, three brands “winning” rank by buying it, and a 9.1% median TACoS that was still climbing. With Q2 mid-flight, here’s what’s playing out, and the three signals worth watching for the rest of the quarter.

Where Q1 left us

Quick recap. Tools category GMV grew 7.8% YoY in Q1. Top-10 brand concentration slipped to 41.2% (down from 44.1% in Q4). Median TACoS across the top 50 hit 9.1%, up 130 bps from Q4. Private label share gained 210 bps, the first material move since 2023.

The headline read healthy. The mechanics didn’t. Three of the top-10 by sales rank were spending ahead of margin to defend share. One had run a sitewide promo from late January through early March that we modeled as eating ~3 months of margin contribution. The other two were scaling DSP to defend an organic-share collapse that’s catalog-rooted, not media-rooted.

Signal 1: TACoS settling vs. drifting

The Q1 number was 9.1%. If Q2 lands at 9.3-9.5%, the category is finding a new natural floor, buyers absorbing higher CPCs, ad-share stabilizing, brands learning to live with the math. If it lands at 10.5%+, we’re watching a structural drift, and the brands sitting at 11-12% TACoS today are about to find out their P&L only worked at the old number.

Mid-April pulls across our managed accounts have median running 9.7%. Not alarming on its own, within seasonal noise. But the spread is widening: bottom-quartile brands are at 12.4%, up from 11.1% in Q1. The category isn’t drifting uniformly. It’s fragmenting, and the brands in the bottom quartile are losing to the ones that did the Cosmo-aware A+ work in Q4.

Signal 2: Private label share, does it stick?

The 210 bps move in Q1 was the headline. The harder question is whether private label holds the gain or hands it back. Two things matter.

First, generic-brand catalog quality. The Q1 share-gain was concentrated in subcategories (drills, multi-tools) where Cosmo’s reranking has gotten confident enough to surface lower-priced alternatives in queries that historically defaulted to brand-name. That confidence is reversible, if review velocity collapses on the generic SKUs, Cosmo will route impressions back to the established brands.

Second, the established brands’ response. In Q4 2024, when private label gained 90 bps in cookware, three name brands ran promos to pull share back inside 60 days. It worked, but the price-led promo cost most of them their full-year margin guidance. If the tools-category incumbents try the same play in Q2, watch their TACoS, that’s where the cost will show up first.

Signal 3: SB video CTR floor

Across the top 50, median Sponsored Brands video CTR fell 11% from Q4 to Q1. That’s not a campaign-level problem; it’s algorithmic. Cosmo’s treatment of repetitive creative tightened in Q1 and most of the category was running creative older than 90 days.

The brands that refreshed creative in February held a 1.4-1.6% CTR floor. The brands that didn’t dropped to 0.8%. For Q2, the question is who refreshes and who doesn’t, and the gap will widen. We expect 8-10 of the top 50 to remain at the 0.8% floor through the end of June, with bid increases failing to recover the CTR gap. Those brands will spend more for less in May and June, and it’ll show up in the Q2 board pack.

Three brands worth watching

We won’t name them. The patterns:

The catalog-late incumbent. A top-15 brand that hasn’t refreshed A+ since 2024. Their organic-share has slipped 11 points YoY on their two anchor SKUs. They’re absorbing it with bid increases, which is reading through to TACoS. They have a Q2 catalog rebuild scheduled, if it lands by mid-May, they recover. If it slips to Q3, they hand the share to a private-label challenger that’s been buying review velocity since February.

The DSP-defensive challenger. Top-25 brand running DSP at $0.42-per-incremental-dollar economics. They’re propping up their organic share with paid display, which is sustainable for one quarter and not two. Watch their May spend curve.

The promo-overhang play. Top-10 brand that ate three months of margin on a sitewide Q1 promo. Their full-year guidance is now mathematically about whether they can hold rank at full price for the rest of the year. They probably can’t, but the way the recovery breaks, bid cuts vs. promo continuation vs. catalog work, will tell us a lot about how the rest of the category responds when the same play happens elsewhere.

What we’re doing on our portfolio

Three things, repeated across every tools-category brand we manage.

SB video creative refresh in May, every account. We’re not waiting for Q2 numbers to confirm the CTR signal, the pattern was clear enough in Q1 to act on. New creative in flight by May 12, A/B against the existing video for two weeks, kill the loser.

Catalog audit on the bottom 30% of SKUs. The category-wide private-label gain is concentrated in subcategories where catalog hygiene moved from “fine” to “behind.” We’re auditing every SKU sitting below 12% organic share on its anchor query, and prioritizing the ones with reviewable A+ debt for rebuild.

TACoS instrumentation. We’re treating catalog as a product, versioned changelog, weekly impression-share pulls, threshold-based negative-keyword harvesting. The brands compounding on Amazon in 2026 are the ones running this loop, not the ones still holding a quarterly review meeting.
