If you have ever ordered a bucket of KFC chicken with an ice-cold Pepsi, your usual meal pairing is about to get a serious shake-up. After nearly four decades of serving PepsiCo beverages, KFC is preparing to make one of its biggest drink menu changes in years. The fried chicken giant is switching to Coca-Cola across its U.S. restaurants, bringing a familiar fast-food rivalry straight to the drive-thru window. But there’s a catch. One fan-favorite Mountain Dew flavor is also preparing to leave, and some customers are already disappointed. Here’s what is changing, when it happens, and what it means for your next KFC run.
KFC Is Saying Goodbye to Pepsi After Nearly 40 Years

On October 15, 2026, KFC officially announced a new partnership with Coca-Cola, ending its long-standing relationship with PepsiCo in the United States.
The transition will begin in January 2027, with Coca-Cola beverages expected to reach all U.S. KFC restaurants by spring 2027.
The change will affect approximately 3,600 restaurants nationwide, according to Coca-Cola. However, customers shouldn’t expect to walk into their neighborhood KFC tomorrow and find everything changed overnight.
The rollout is still a few months away, and individual restaurants may transition at different times.
For longtime customers, this is a significant adjustment. Pepsi has been closely associated with KFC since 1986, when PepsiCo purchased the chicken chain.
Interestingly, Coca-Cola actually had a substantial relationship with KFC before that acquisition. So, in a way, this move is less about introducing something completely new and more about bringing back an old partnership.
One Popular Mountain Dew Flavor Is Leaving KFC

Here’s where things get a little disappointing for fans of unusual soft drinks.
Mountain Dew Sweet Lightning, the peach-and-honey-flavored soda created specifically for KFC, is expected to disappear from the chain’s menu at the end of 2026.
Introduced in 2019, Sweet Lightning became one of KFC’s most distinctive beverage offerings. Unlike regular Mountain Dew, this exclusive flavor wasn’t something customers could simply grab at their neighborhood grocery store.
According to October reporting on a statement from PepsiCo, Sweet Lightning will remain available at KFC through December 31, 2026.
After that, its future becomes less certain.
PepsiCo has indicated that it intends to explore other ways for customers to enjoy Sweet Lightning. However, no replacement restaurant partner, retail launch, or alternative distribution plan has been confirmed.
So, if Sweet Lightning is your go-to drink whenever you order fried chicken, you may want to enjoy it during its remaining time at KFC.
The good news? The flavor hasn’t been confirmed as permanently discontinued everywhere.
What Coca-Cola Drinks Will KFC Serve?

Naturally, one of the biggest questions is what customers will actually find at the soda fountain once Coca-Cola takes over.
Although the supplier change has been confirmed, KFC hasn’t released a complete nationwide beverage lineup.
That means it’s too early to say exactly which Coca-Cola products will be available at every participating location.
Customers might be wondering about familiar drinks such as Sprite, Diet Coke, or Coca-Cola Zero Sugar, but their inclusion hasn’t been officially confirmed in the partnership announcements.
The company also hasn’t announced new drink prices, cup sizes, or special promotional offers connected to the transition.
For now, the certainty is that Coca-Cola will become KFC’s new beverage partner across the United States.
The exact menu choices should become clearer as the rollout approaches.
KFC Is Thinking Beyond Traditional Fountain Drinks
There’s another interesting detail behind this partnership.
KFC isn’t simply swapping one cola supplier for another to put different logos on its drink machines.
The company also wants to explore new beverages and give customers additional reasons to visit.
One example is KFC’s Open House restaurant in McKinney, Texas, where the chain has introduced specialty beverages, including iced lattes, boba refreshers, and Krunch shakes.
That doesn’t mean every KFC restaurant will suddenly start selling boba drinks or specialty coffee.
The McKinney restaurant serves as an example of KFC’s broader experimentation, not proof of a nationwide specialty-drink launch.
Still, it’s an interesting direction for a brand traditionally associated with fried chicken, mashed potatoes, biscuits, and family buckets.
KFC appears interested in becoming a destination for snacks and drinks as well as traditional meals.
The Chain Is Also Introducing Smaller Snack Options
The beverage announcement isn’t the only recent development at KFC.
Earlier in October, the company introduced Go Buckets, a smaller snack offering with a starting price of $3.49 at participating restaurants.
Customers can choose four chicken nuggets, two chicken wings, or one chicken tender.
Each option comes with a choice of individual fries or potato wedges, creating six possible combinations.
The packaging is also part of the appeal. KFC describes Go Buckets as its first bucket designed to fit inside a standard car cupholder.
That’s a practical idea for customers looking for something smaller than a traditional chicken meal.
However, Go Buckets don’t include a drink in the announced offer, and prices and availability vary by location.
Combined with the upcoming beverage changes, the new snack format shows how KFC is exploring different ways to attract customers.
Why Is KFC Making So Many Changes?
Behind these menu updates is a much larger business goal.
KFC has been working to strengthen its position in the competitive American fast-food market.
According to Yum! Brands’ financial reporting, KFC’s U.S. system sales declined 2% during the second quarter of 2026 compared with the same period a year earlier.
That doesn’t mean the entire global business is struggling. KFC’s worldwide system sales increased 6%, excluding foreign exchange effects, during the same quarter.
The challenge is particularly important in the United States, where customers have plenty of chicken restaurants competing for their money.
Chains such as Chick-fil-A and Popeyes make competition especially intense.
KFC’s broader turnaround effort, which the company calls its “Kentucky Fried Comeback,” includes menu innovation, new product formats, and a renewed focus on customer experience.
The Coca-Cola partnership is another piece of that strategy.
Of course, switching beverage suppliers doesn’t automatically mean more customers will start buying chicken.
The real test will be how shoppers respond once the new drinks arrive.
Not Everyone Is Celebrating the Switch
As you might expect, Coca-Cola and Pepsi fans have different opinions about the announcement.
Some customers welcome the change, especially those who prefer Coca-Cola products.
Others have expressed disappointment about losing PepsiCo beverages, particularly Mountain Dew Sweet Lightning.
Allrecipes reported mixed social media reactions following the announcement, including excitement about Coca-Cola’s arrival and frustration over the departure of familiar drinks.
These individual comments don’t establish how most KFC customers feel, but they show why a seemingly simple soda switch can become a surprisingly personal issue.
For some people, a particular drink is part of the entire fast-food experience.
What Customers Should Know Before Their Next KFC Visit
The biggest thing to remember is that KFC’s drink menu hasn’t switched nationwide yet.
PepsiCo beverages remain part of the current transition period, with Coca-Cola’s rollout scheduled to begin in January 2027.
Sweet Lightning is expected to remain at KFC through December 31, 2026, although availability may vary at individual restaurants.
Meanwhile, KFC’s familiar fried chicken offerings aren’t being discontinued as part of this beverage announcement.
For regular customers, the change might be as simple as getting a Coke instead of a Pepsi with their next chicken bucket.
For loyal Sweet Lightning fans, however, losing an exclusive favorite could be harder to swallow.
Either way, after nearly 40 years of Pepsi at KFC, America’s fried chicken-and-soda routine is about to look a little different.
