Carbonated Soft Drinks (CSD)

Carbonated Soft Drinks (CSDs) encompass traditional legacy sodas, diet sodas, and energy drinks (such as monster-energy). Historically dominated by heritage FMCG giants like coca-cola and pepsico, CSDs represent a $1.3 trillion global market. The category is characterized by a high-volume, low-margin business model relying on cheap, highly scalable ingredients like high-fructose corn syrup and basic carbonated water, resulting in highly optimized and low Cost of Goods Sold (COGS).

Once viewed as a distinct category from alcohol, CSDs are currently facing severe disruption and direct cannibalization from shifting consumer health trends, the rise of non-alcoholic (NA) beer, functional beverages, and the widespread adoption of glp-1-medications.

Structural Market Shift and Generational Decline

The CSD category is facing a structural market shift driven by consumer concerns over obesity, diabetes, and overall health. Consumers are pivoting toward wellness-oriented adult-soft-drinks and functional beverages that offer low or zero sugar alongside active health benefits.

This decline is heavily driven by generational shifts. Gen Z consumers are planning significant reductions in traditional soft drink spending—projecting up to a 9% drop—pivoting instead toward sparkling waters, seltzers, and NA alternatives.

Health Trends and Functional Disruption

Traditional CSDs and energy drinks face severe headwinds from health-conscious consumers migrating toward products that offer functional-premiumization. This shift is exposing major vulnerabilities in both full-sugar and diet CSDs.

The Sugar Deficit

On the full-sugar front, CSDs are losing occasions to NA beers. A typical non-alcoholic beer contains 8 to 10 times less sugar than standard CSDs, positioning NA beer as a “better-for-you” alternative that still provides carbonation and flavor without the severe glycemic spike.

The Diet Soda Paradox

Historically, diet and zero-calorie sodas served as a safe harbor for weight-conscious consumers. However, this is changing rapidly due to the-diet-soda-paradox driven by the rise of glp-1-medications. Because GLP-1 users have suppressed appetites, they require high nutrient density in small volumes. Diet sodas provide zero nutritional benefits and contain artificial sweeteners (like sucralose and aspartame) that may increase insulin resistance and stimulate appetite, directly counteracting metabolic goals.

As a result, traditional diet sodas are losing market share to functional, prebiotic sodas (such as olipop and poppi) that actively support gut health, offer mental focus benefits, and mitigate the gastrointestinal side effects of weight-loss medications.

Unit Economics and Legacy Response

Unlike traditional CSDs, functional beverages operate on a low-volume, high-margin model driven by functional-premiumization. While CSDs benefit from massive economies of scale, functional beverages face elevated COGS due to premium raw materials, complex manufacturing (like aseptic filling and probiotic viability), and heavy R&D required for taste masking.

To defend their market share against this disruption, legacy CSD manufacturers are executing massive M&A activity (e.g., PepsiCo’s $1.95 billion acquisition of poppi) and heavy internal R&D investments to develop their own functional formulas.

Social Signaling and NA Beer Cannibalization

As major brewers execute a multi-beverage-strategy, they are actively positioning NA beers as adult-soft-drinks to capture volume directly from the CSD category.

In social settings, standard CSDs like Diet Coke lack the cultural cachet of alcohol. NA beers mimic the visual and cultural cues of drinking, providing a sense of inclusion and sophistication that traditional CSDs cannot match.

The Pricing Paradox

While NA beers and functional beverages are functionally substituting CSDs for many consumers, a significant tension exists in pricing. CSDs are generally priced as commodities, whereas NA beers and functional sodas rely heavily on premiumization, commanding craft-beer prices.

This dynamic feeds into the-rip-off-paradox, raising questions about whether consumers will continue to substitute cheap CSDs with expensive NA alternatives for at-home, solo consumption occasions where social signaling is irrelevant.
