2026 Pharmacy Benefit Trends: What Employers Need to Know
The pharmacy market has been on a steady growth trajectory for years, so it’s no surprise that prescription drug spending continues to rise. But beneath the surface, something more significant is happening. The structure of the pharmacy ecosystem itself is shifting.
A recent review of the 2026 Economic Report on U.S. Pharmacies and Pharmacy Benefit Managers from the Drug Channels Institute highlights several trends that signal a market in transformation. While costs remain a concern, these changes could create new opportunities for employers to rethink how they purchase and manage pharmacy benefits.
Below are the key takeaways from the report.

The Pharmacy Market Is Changing Faster Than Many Employers Realize
For many employers, pharmacy benefits have historically felt like a black box—complex contracts, opaque pricing, and limited visibility into how medications move through the system.
But the pharmacy market is beginning to shift. Pricing models are evolving, new purchasing channels are emerging, and employers are demanding greater transparency from the organizations managing their pharmacy benefits.
Understanding these structural changes is becoming increasingly important as pharmacy spending continues to play a larger role in overall healthcare costs.
Prescription Drug Spending Is Growing, But the Drivers Are Concentrated
Prescription drug spending continues to rise, but the growth is becoming more concentrated among a smaller number of therapies.
In 2025, total pharmacy dispensing revenue reached approximately $751 billion, with GLP-1 medications responsible for nearly two-thirds of the increase in spending. These drugs ,commonly used for diabetes and weight management, have quickly become some of the most talked-about medications in the healthcare market.
This dynamic means that a small number of high-impact therapies are driving a significant share of prescription drug spending. For employers managing health plans, that concentration makes pharmacy benefit strategy more important than ever.
Coverage decisions, formulary design, and pharmacy benefit management all play a role in how organizations manage the impact of these rapidly growing drug categories.
The Traditional PBM Rebate Model Is Beginning to Shift
For decades, the pharmacy supply chain has relied heavily on a rebate-driven pricing model.
Drug manufacturers often set high list prices, while pharmacy benefit managers negotiate rebates in exchange for favorable formulary placement. While those rebates can offset costs for health plans, they have also created a system where the true price of medications can be difficult to understand.
That model is beginning to shift. Increasingly, net pricing—what plans actually pay after rebates—is becoming the primary point of competition.
Analysts describe this change as the emergence of a net-pricing drug channel, where transparency and direct pricing may gradually replace the traditional rebate-heavy system. For employers seeking more clarity around pharmacy benefits, this shift could lead to a more transparent marketplace.
PBM Market Concentration Is Still Dominant
Despite ongoing calls for reform, the pharmacy benefit manager market remains highly concentrated.
The three largest PBMs (CVS Caremark, Express Scripts, and OptumRx) continue to process roughly 80% of all prescription drug claims in the United States.
However, the environment around PBMs is changing. Policymakers are increasing scrutiny around pricing transparency and rebate structures, while employers are asking more detailed questions about contract terms, spread pricing, and overall pharmacy benefit strategy.
As transparency expectations grow, the relationship between employers, PBMs, and pharmacy benefit consultants may evolve as well.
Retail Pharmacies Are Facing New Economic Pressures
The traditional retail pharmacy model is also undergoing significant change.
Over the past several years, major pharmacy chains have closed thousands of store locations as operating margins tighten and reimbursement structures evolve.
At the same time, alternative purchasing models are gaining traction. Cash-payment pharmacies, discount card platforms, and direct-to-consumer drug channels are expanding rapidly and offering patients new ways to access medications.
These emerging models could reshape how prescriptions are purchased and distributed in the future, adding more competition to the pharmacy ecosystem.
What These Pharmacy Trends Mean for Employers
Taken together, these trends highlight a broader transformation in the pharmacy market.
Prescription drug spending is rising, but it is also becoming more concentrated among certain therapies. Pricing structures are evolving as the industry shifts away from traditional rebate models. Meanwhile, new pharmacy distribution channels are beginning to challenge long-standing systems.
The big takeaway is clear: the pharmacy market isn’t just getting bigger…it’s being rebuilt.
For employers, this transformation creates an opportunity to rethink how pharmacy benefits are structured and purchased. Organizations that stay informed about pharmacy benefit trends and actively engage in the conversation will be better positioned to control costs while ensuring employees maintain access to the medications they need.
As the pharmacy landscape continues to evolve, thoughtful pharmacy benefit strategy will become an increasingly important part of managing employer health plans.
