$BTC Bitcoin is coming to the drive-thru.

American fast food chain Steak ‘n Shake said Thursday it will begin accepting the world’s largest crypto at all of its U.S. locations starting May 16, giving its more than 100 million customers the option to pay for milkshakes and burgers in BTC.

“The movement is just beginning,” the company posted on X.

Unlike high-margin retailers, fast food chains run on thin margins and high volume, making Steak ‘n Shake’s Bitcoin rollout a real-world stress test for the crypto’s speed, cost, and usability at scale.

The integration was initially teased in March, when the chain posed a question on social media: “Should Steak ‘n Shake accept Bitcoin?” which drew engagement from figures like former Twitter CEO Jack Dorsey.

Since then, the company has built momentum around crypto-curious marketing, culminating in Thursday’s formal announcement.

Steak ‘n Shake has also leaned into Bitcoin’s cultural iconography, previously tweeting an image of a Mars-bound cargo ship stamped with the Bitcoin logo in reference to Robert F. Kennedy Jr.’s vocal promotion of beef tallow and Tesla CEO Elon Musk’s interplanetary aspirations.$BTC
