Tracking coverage over H1 2026
These are price change events, not daily snapshots. Volume reflects how much of the catalog was in active sync during the window.
In our set, prices climbed more often than they fell
Among quality-filtered products with enough history, 5,868 ended H1 at least 20% higher than their first observed price, vs 2,313 that fell 20%+. Average swing across the set: 31.7%. This is an observational signal from our tracked catalog — not a measure of inflation.
Merchant pricing pressure
A constructed index from median swing, share of volatile SKUs, and deep temporary dips that later recovered — a rough proxy for aggressive promotional / list-price gymnastics. Not a claim about any merchant's financial health.
Walmart is first-party only (189 SKUs; 4,395 marketplace listings excluded). That keeps marketplace noise out and improves merchant diversity elsewhere.
Callouts worth a look
Hand-picked from filtered lists — drops, climbs, yo-yos, checkout gaps, and the occasional “on sale” that wasn't actually cheap.

Methodology
- Window: H1 2026 (2026-01-01 → 2026-07-01). Period key:
h1-2026. - Source: LMK
price_historychange events (≥ $0.01 delta), not daily price snapshots. - Quality filter: published products, ≥3 observations, prices between $15 and $2,000, title hygiene (excludes used/pre-owned/etc.).
- Walmart: first-party sellers only (
metadata.seller_party = first). Marketplace / unset / unknown excluded — 4,395 Walmart products left out of this window's qualified set. - Checkout gaps require 2+ merchants on the same UPC/EAN/GTIN with overlapping title tokens.
- Merchant pressure is a constructed index (median swing + volatility share + deep-dip recoveries), not audited financial data.
- Snapshot version h1-2026-v1, generated Tue, 14 Jul 2026 16:08:10 GMT.
Based on LMK's tracked catalog of price-change events in H1 2026. This is not a scientific study, not CPI, and not representative of all retail. Selection bias, coverage ramp, and merchant mix apply. Walmart listings are limited to first-party sellers only.
