# Buy-Box Win Rate, Walmart Marketplace

> Buy-Box Win Rate for Walmart Marketplace stores. Tracked live in Vortex IQ Nerve Centre. How to read it, why it matters, and how to act on it.

**Card class:** [Hero](/nerve-centre/overview#card-classes-explained)  •  **Category:** [Marketplace](/nerve-centre/connectors#connectors-by-type)

## At a glance

> This card shows how often your offers win the Walmart Buy Box, the default add-to-cart spot on a shared product page. Walmart often awards the Buy Box to the lowest-price seller, including WFS offers and Walmart first-party, so a drop here usually means you have been undercut on price or fulfilment promise. Sellers watch it because Buy Box ownership is where the vast majority of marketplace sales actually happen.

| **What it counts**    | The percentage of eligible offers where your listing holds the Walmart Buy Box.                                       |
| **Sample type**       | Backend API data from Walmart Marketplace, refreshed on the standard data refresh.                                    |
| **Why it matters**    | The Buy Box captures most sales on a shared listing, so a falling win rate directly cuts your conversion and revenue. |
| **Reading the value** | Higher is better; a reading below the alert threshold signals you are losing the Buy Box on too many offers.          |
| **Currency**          | percent                                                                                                               |
| **Time window**       | `30D vsP`                                                                                                             |
| **Alert trigger**     | `<70%`                                                                                                                |

## Calculation

Vortex IQ measures the share of your eligible offers that currently hold the Buy Box across the selected window and compares it against the prior period to show direction. The result is rendered as a gauge so you can see at a glance how close you are to the threshold. As the At a glance summary notes, Walmart's Buy Box logic leans heavily on price and fulfilment promise; the worked example below shows how a competitor's repricing move can pull this figure down quickly.

## Worked example

*A representative reading of **Buy-Box Win Rate** for a typical merchant on Walmart Marketplace.* Over the 30 days to 12 Mar 26 a seller sees Buy-Box Win Rate fall from a representative 84% to 66%, below the threshold and down versus the prior period. Checking competing offers shows a rival has begun undercutting on several shared SKUs, and a WFS competitor is winning on delivery promise for others. The reading means price and fulfilment competitiveness have slipped, so the action is to reprice the affected SKUs and weigh moving high-velocity items into WFS to match the delivery promise. For deeper investigation, use Vortex Mind to trace upstream causes; for natural-language exploration, ask Ask Viq.

| ------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------- |
| [`wal_xc_price_parity`](/nerve-centre/kpi-cards/walmart-marketplace/skus-priced-differently-vs-amazon) | Price gaps versus Amazon often explain Buy Box losses on shared SKUs.        |
| [`wal_wfs_vs_seller`](/nerve-centre/kpi-cards/walmart-marketplace/wfs-vs-seller-fulfilled-revenue-mix) | Shows how much of your revenue rides on WFS, which strengthens Buy Box odds. |
| [`wal_total_revenue`](/nerve-centre/kpi-cards/walmart-marketplace/total-revenue)                       | Links Buy Box ownership to the revenue it ultimately drives.                 |
| [`wal_top_listings`](/nerve-centre/kpi-cards/walmart-marketplace/top-listings-by-revenue)              | Identifies which high-value listings most need to hold the Buy Box.          |
| [`wal_avg_lqs`](/nerve-centre/kpi-cards/walmart-marketplace/listing-quality-score)                     | Higher listing quality supports Buy Box eligibility alongside price.         |

## Reconciling against Walmart Seller Center

**Where to look in Walmart Seller Center:**

Check the Listing Quality or Buy Box reporting where Walmart indicates Buy Box ownership and offer competitiveness, and review item-level price and shipping detail for affected SKUs. Repricing and competitive-price signals also live in the Item or Catalog area.

**Why the Vortex IQ value may legitimately differ:**

| Reason                                                                                                         | Direction | What to do               |
| -------------------------------------------------------------------------------------------------------------- | --------- | ------------------------ |
| **Period boundary.** Vortex IQ uses 30D vsP rolling by default; Seller Center may use calendar periods.        | Variable  | Match the period range.  |
| **Time zone.** Seller Center uses the account time zone; Vortex IQ aligns to the merchant reporting time zone. | Marginal  | Confirm time zone match. |
| **Filter scope.** Profile-level filters (fulfilment type, test orders) may narrow the Vortex IQ view.          | Variable  | Match filter settings.   |

**Cross-connector reconciliation:** complement with sibling cards in the same category for the full diagnostic picture. For divergence investigations, use Vortex Mind.

## Known limitations / merchant FAQs

**Q: How often does Buy-Box Win Rate update?**
The card refreshes on the standard data refresh (typically every 30-60 minutes for live integrations). For real-time signals, force a manual refresh from the dashboard.

**Q: Why does my Walmart Seller Center show a different number?**
Buy Box ownership changes continuously as competitors reprice, so Seller Center and Vortex IQ can sample slightly different moments, and the two may use different period boundaries. Filter scope (fulfilment type or test orders) can also change which offers are included.

**Q: Why am I losing the Buy Box even when my listing is high quality?**
Walmart weights price and fulfilment promise heavily, so a lower-priced rival or a WFS offer with a faster delivery estimate can take the Buy Box even when your listing quality is strong; compare against the price parity and WFS sibling cards.

**Q: Can I customise the alert threshold?**
Yes, sensitivity thresholds are configurable per profile in the Sensitivity tab. Adjust to match your business baseline rather than relying on the generic default.
