The Golden Arches just stopped planning its entire drink menu around one partner, and that handshake from 1955 suddenly looks a lot less exclusive.
McDonald’s is loosening its 70-year grip-and-grin with Coca-Cola, rolling out custom sodas, refreshers, and a Red Bull energy line because U.S. burger growth has stalled and rivals proved drinks alone can mint billions. Coke still supplies the fountain, but it is no longer the only name at the table.
Picture a Coke executive named Waddy Pratt pulling into a scrappy hamburger stand in Des Plaines, Illinois, in 1955, watching a guy named Ray Kroc hose down the parking lot. A handshake later, two brands became “attached at the sip,” as Coke put it on LinkedIn last year. Seven decades on, the marriage is still intact. It is just no longer monogamous.
What Happened
McDonald’s this spring introduced its own custom sodas and refreshers, and it is gearing up to launch a line of energy drinks anchored by Red Bull, a first for the Golden Arches. Coke executives are publicly fine with it and privately hustling to keep up. New CEO Henrique Braun, who took the top job in March, called the partnership “fantastic” while making clear Coke wants to stay the number one beverage provider “for all consumers.” Translation: the keeper of the handshake now has competition inside its own biggest account.
The Backstory
That 1955 deal was a masterclass in standardization. Pratt and Kroc figured uniform products meant uniform quality and bigger purchasing power, so Coke built an entire internal unit, The McDonald’s Division, just to service the account. Coke bumped 7UP off the fountains with Sprite in the 1980s. Franchisees installed filtration gear and chilled syrup just above freezing to trap more fizz. Coke even pitched the extra value meal in the 1980s, the sandwich-soda-fries bundle that became fast-food gospel. For decades, the relationship printed money for both sides.
Then tastes shifted. McDonald’s moved to an a la carte dollar menu in late 2002 that sidelined Coke combos. Soda sales slid. Younger drinkers chased exotic flavors and TikTok-ready colors. Coke’s own attempts to innovate at McDonald’s, from the Freestyle self-mix dispenser to bottled Vitaminwater, mostly sputtered.
The Plan
McDonald’s CEO Chris Kempczinski, a former PepsiCo executive who arrived in 2015, has been eyeing the drink aisle for years. The global beverage market nearly doubled over 15 years to $100 billion, and he wants a real slice. The 2023 CosMc’s spin-off concept flamed out, with its five locations closing roughly 18 months later, but McDonald’s harvested the lessons and put the CosMc’s leader in charge of beverage development in 2025. The new lineup includes six specialty drinks like Strawberry Hot Honey Lemonade and a Sprite Lunar Splash, plus the Red Bull energy push tested in Colorado and Wisconsin. Coke is still in the mix, helping concoct the brightly colored dirty sodas with Sprite and syrups. But Red Bull, as one TikTok reviewer put it, “stole the show.”
The Business Model Angle
This is a single-supplier dependency quietly turning into a portfolio. For 70 years McDonald’s outsourced its entire drink strategy to one partner, which is efficient until the partner’s category stops growing. The lesson for operators: your most reliable vendor relationship can become your biggest blind spot. Starbucks turned cold foam and Refreshers into a $2 billion brand. Taco Bell and PepsiCo built Baja Blast into a $1 billion-a-year hit. Those numbers showed McDonald’s that beverages are not a side dish to burgers, they are a high-margin product line worth owning. When a category you depend on goes flat, the smart move is not to abandon the partner but to widen the bench, keep the proven supplier for the core, and add specialists where they create new revenue.
The Risk
Diversifying sounds clean on a slide and gets messy in 45,700 restaurants, including 13,730 in the U.S. More suppliers means more complexity, more equipment, and franchisees who already found bottled drinks less profitable than fountain soda the last time around. Cannibalization is the quiet threat too: McDonald’s says early tests show new drinks pulling from sweet tea and lemonade rather than soda specifically, but novelty drinks can fade fast, and CosMc’s is a fresh reminder that splashy concepts do not always stick. Coke, with $47.9 billion in annual revenue, is not going to roll over either. It is now showing off rainbow frozen energy drinks and pink concoctions before the term sheets are even signed, which one Coke executive admitted is “a little uncomfortable for us.”
Quick Questions
Is McDonald’s dropping Coca-Cola?
No. McDonald’s says it is committed to the longtime partnership and Coke still supplies the fountain. It is just adding other beverage suppliers and brands alongside Coke for the first time at this scale.
Why is McDonald’s adding Red Bull?
U.S. burger sales growth slowed, and energy drinks are a fast-growing, high-margin category. The Red Bull line is the first energy-drink push for the Golden Arches and tested well enough that customers called it addictive.
How big is the McDonald’s beverage opportunity?
Kempczinski has pointed to a global beverage market that nearly doubled in 15 years to $100 billion. Rivals proved the upside: Starbucks Refreshers became a $2 billion brand and Baja Blast tops $1 billion a year.
What happened to CosMc’s?
McDonald’s launched the drink-focused CosMc’s concept in 2023, but its five locations closed about 18 months later. The company kept what it learned and folded those lessons into its current beverage strategy.
The Business Model Analyst Take
The McDonald’s and Coke story is a reminder that loyalty and strategy are not the same thing. A partnership can be genuinely great and still hold you back if you let it define your entire category. McDonald’s is not divorcing Coke, it is refusing to let one relationship decide what it sells. For founders and operators, the takeaway is sharp: audit the dependencies you have stopped questioning, because the supplier you have trusted for decades may be quietly capping your upside. Keep what works, add what grows, and never outsource your whole strategy to someone else’s product road map.
