Centene Corporation CNC is rebuilding its Marketplace business after a difficult 2025, with better pricing, moderating medical costs and improved underwriting dynamics supporting a sharp improvement in profitability. The recovery is becoming an important contributor to Centene’s broader margin-restoration strategy.
The Marketplace health benefits ratio improved to 79.2% in the second quarter of 2026 from 90.6% a year ago. The improvement reflected better medical cost trends and risk-adjustment dynamics. Centene also benefited from a $180 million favorable 2025 CMS risk-adjustment reconciliation during the quarter.
Importantly, the improvement is not dependent solely on membership expansion. Marketplace membership stood at around 3.5 million at the end of June 2026, down substantially from 5.9 million a year ago. However, the business is now expected to generate a 4.5%-5% pretax margin in 2026, compared with the previous 3% outlook. This suggests that tighter pricing and a more favorable risk profile are helping Centene prioritize profitability over volume.
The key challenge now is sustaining those gains as eligibility reviews could cause further membership attrition in the second half of 2026. Centene’s 6.9% adjusted SG&A expense ratio in the second quarter of 2026, which improved from 7.1% a year ago, and increased use of technology, automation and AI could provide another layer of support. If these trends hold, the Marketplace business could provide a more dependable earnings contribution and support Centene’s overall profit growth over time.
How Are Competitors Faring?
Some of CNC’s major competitors in the healthcare service provider space are UnitedHealth Group Incorporated UNH and Elevance Health, Inc. ELV.
UnitedHealth is taking a more selective approach to its individual exchange business, with pricing and benefit adjustments aimed at better aligning premiums with medical costs. UNH’s medical care ratio improved to 86.7% in the second quarter of 2026 from 89.4% a year ago.
Elevance is also working to improve Individual ACA profitability through tighter pricing and plan repositioning. ELV is also investing in clinical oversight, payment integrity and value-based care to improve cost management and support more consistent margins.
