Oscar Health said it will report a loss from operations of about $230 million and a net loss of roughly $228 million for the quarter ended 30 June, according to preliminary figures released ahead of its scheduled earnings report on 6 August. Despite the second-quarter shortfall, the New York-based insurer raised its full-year 2025 revenue forecast to $12.0 billion–$12.2 billion from $11.2 billion–$11.3 billion. It now expects a full-year operating loss of $200 million to $300 million and a medical loss ratio of 86%–87%, reflecting higher claims costs in its Affordable Care Act plans. Oscar attributed the revised outlook to new risk-adjustment data showing greater morbidity in ACA marketplaces and continued elevated utilisation by its 2 million members. The company said it will resubmit 2026 premium rate filings in states representing about 98% of its membership to account for the higher risk profile, joining other insurers confronting rising costs in the individual market.
