Steak 'n Shake boosts Bitcoin reserve and reports 18% 2026 sales growth after May 2025 rollout

Steak 'n Shake reports that same-store sales climbed 18% in 2026 after it began accepting Bitcoin payments in May 2025 and building a dedicated Bitcoin reserve. The fast-food chain says it now holds about $15 million in Bitcoin, has nearly halved its transaction fees compared to credit cards, and plans to launch a vesting Bitcoin bonus for hourly staff while expanding into El Salvador.
