The price of Bitcoin rose on Monday as McDonald’s prepared for the McRib’s return in the U.S., mirroring momentum seen alongside the sandwich’s showing last year.

For several years, the sandwich’s availability has been informally linked to periods of strength for the leading digital asset by market cap, as well as stock indices like the S&P 500.

The dynamic was referenced by McDonald’s Senior Marketing Director Guillaume Huin, who said on X on Monday that the barbecue-flavored fan favorite “has recently found new meaning on [the] internet within the trading and crypto community.”

“Some claim Bitcoin and S&P 500 tend to perform well after the McRib makes a comeback, particularly in 2017, 2020, 2021,” Guillaume said. “Coincidentally, when the McRib returned to stores in December 2024, Bitcoin hit a new all-time high.”

Last year, the McRib returned as U.S. President Donald Trump’s reelection unleashed animal spirits in the crypto market, pushing Bitcoin above the $100,000 mark for the first time. This year, the sandwich returns as a 40-day government shutdown shows signs of potentially ending, leading to a rise in the price of Bitcoin and other top assets on Sunday..

According to Huin, McRib is set to return to restaurants nationwide starting on Tuesday, but it will only be available for a limited amount of time, as it has been since Americans got their first taste of BBQ sauce, pickles, onions, and pork in 1981.

The correlation between the McRib’s reintroduction and Bitcoin gains may be savory for some, but the trend is far from solid. In 2018 and 2022, the saucy sandwich’s return preceded a steep decline in Bitcoin’s price to $3,250 and $15,500, respectively.

If the McRib’s return is correlated with anything, it’s likely related to a decline in bulk pork prices, according to an informal study published in 2011 called “A Conspiracy of Hogs.”

Within the cryptosphere, the significance of the McRib’s return has been popularized by a pseudonymous X user named Internbrah, who works on the Monad blockchain team.

Last year, Internbrah posited to Decrypt that the sandwich only moves markets when it returns to the U.S., as the McRib returned to restaurants in the UK for the first time in nearly a decade.

Although the McRib was slated to return on Tuesday, there were already sightings of the sandwich across the U.S., according to McRib Locator. Because the sandwich’s availability is not guaranteed, the website tells users to always call ahead.

Bitcoin changed hands around $105,600 on Monday, a 1% increase over the past day, according to crypto data provider CoinGecko. That meant Bitcoin’s price had increased 6% from $98,800, the mark from the last time that so-called McRib SZN officially started.
