01 — A World Cup window everyone was discounting into.

Forme® Science makes premium posture and recovery apparel. A tournament-sized moment was coming, and the default play was a tournament-sized sale.

They wanted the attention without teaching their customers to wait for a markdown.

02 — 100% back if the USA reached the Final.

Shop Forme with code TEAMUSA through the July 1 cutoff, and if the U.S. Men’s National Team reached the 2026 World Cup Final, the entire product subtotal came back as cashback. No claim forms, no hoops, and the gear shipped either way.

03 — The payout was hedged on Kalshi.

Playably priced the odds of that result on Kalshi and carried the position, which made this the first e-commerce promotion hedged on a prediction market. Forme sold at full price and never took on the exposure. Nothing was bought to promote it, and nothing on the site pointed to it. The offer page was unlisted, with no homepage banner and no navigation link, so shoppers reached it only from the link shared on social and in Forme’s own SMS and email. Every paid campaign running that week was always-on prospecting that pre-dated the promotion and never mentioned it.

04 — The outcome: no payout, and a category first.

The USA did not reach the Final. Peak-day sales ran 36% higher than the same weekday the week before, traffic to the men’s hero product ran nearly 20×, men’s share of the cart doubled (11.7% vs. a 5.6% baseline) and baskets were 17% bigger. Every enrolled order stayed at full price, the campaign email drove 2.3× the revenue of Forme’s average recent send with zero discount, $0 of cashback was owed, and the mechanic itself carried the story onto Modern Retail, PRNewswire, EQS, ADVFN and USA Today’s press section.

Why it worked

Four reasons this beats a World Cup sale.

A

Stakes, not markdowns.

Shoppers paid full price for premium posture apparel and got a real shot at every dollar back. Nothing was discounted to create the urgency, and the campaign email still drove 2.3× the revenue of Forme’s average recent send.

B

The risk sat on a market.

Playably priced the payout on Kalshi and carried it. Forme’s margin was never exposed to the result of a football match.

C

A missed trigger is the product working.

The USA did not reach the Final, so $0 of cashback was owed and Forme kept full-price revenue on every enrolled order.

D

The mechanic earned the coverage.

A category first earned coverage from Modern Retail, PRNewswire, EQS, ADVFN and USA Today’s press section without a media buy behind it.
