The lift isn't uniform — bigger sellers spike harder

Daily units ordered — July 2025 (US)

The 4-day spike (Jul 8–11) is unmistakable in aggregate. But that 3.0× blend is carried by deal-featured hero ASINs; the long tail barely moved.

Per-ASIN lift model

ASIN-level history isn't retrievable through the connector, so lift is assigned by volume tier — reflecting the pattern that top sellers get deal badges & placement (big lift) while the tail does not. Calibrated so the volume-weighted blend = 3.05×, reproducing last year's observed 3.0×.

Methodology & assumptions. Aggregate lift from Amazon Sales & Traffic (by date), US: Prime Day 2025 (Jul 8–11) averaged 3,231 units/day vs 1,072/day the prior week = 3.01× blended; peak day Jul 8 = 3.98×. Per-ASIN units history for last Prime Day could not be retrieved (the connector's ASIN-level report and order-line export both time out upstream), so per-ASIN lift is modeled by volume tier rather than measured — top sellers receive deal placement and lift hardest (~3.3×), the long tail much less (~1.1–1.3×). Tiers are calibrated so the current-catalog volume-weighted blend (3.05×) reproduces the observed 3.0× aggregate. Run-rate, sellable quantity, inbound and days-of-supply are current snapshots from the FBA Restock & Manage-Inventory reports. "Available now" = FBA fulfillable; reserved/in-transit-to-customer units excluded. Inbound = working + shipped not yet receivable; not all of it will check in before the event. Several current hero SKUs (Classic Chicken, the "EB" variety pack, the collagen drink mixes) launched after July 2025 and had no Prime Day history regardless. SKUs you place into actual Prime Day deals should be bumped a tier — use the scenario slider or treat them as Hero. Units unless noted.
