Post-Black Friday 2025: What the Data Showed

BF 2025 moved R$ 9.7 billion in 5 days (Neotrust/Confi, Dec/25), with nominal growth of 4.3% over 2024 — but average depth landed at 32%, below the 35-40% the market had projected. Stackable coupons dominated the mechanics and redefined what “aggressive promotion” means.

BF 2025 came out different from what was expected

Three signals broke with the pattern of the last 4 years:

3 competitive patterns that repeated

1. The “Rising” curve in 3 stages

Large stores followed a clear staggered curve: 20% (warm-up week) → 30% (BF week) → 40% (Friday + Cyber Monday). Whoever calibrated against this pattern avoided reacting too early.

2. Aggressive “Flat” curve

Mid-sized stores opened with 35-40% straight from Monday of BF week. A fast-capture strategy — anyone who reacted only on Thursday missed the window.

3. The “stackable coupon”

It replaced the single high-depth coupon. It combines a 10% coupon + free shipping + 12× interest-free installments. Perceived value without burning margin in a single layer. It was the most common mechanic among stores with 50-200 active SKUs.

What this sets up for 2026

1. The stackable coupon will become the baseline. Anyone still planning BF 2026 with an aggressive single coupon is already playing last year’s game.
2. Universal free shipping is in decline. It will be replaced by conditional free shipping above R$ 199-249.
3. The useful reaction window shrank. Whoever captures a change in ≤2h is 3.2× more likely to hold the sale than at 8h+ (McKinsey, 2023).

The early signal to map right now

Start mapping which of your competitors experimented with stackable coupons in 2025. Those will be the benchmark in 2026 — they will probably scale and refine the mechanic.
