Minnesota is announcing double-digit premium increases next year for people who buy health insurance on their own, including bigger jumps than what insurers originally proposed in July. The premium increases are for "Obamacare" plans purchased through the state's health insurance marketplace, MNsure. "Health insurance rates for 2026 are going up, and the numbers are alarming," Minnesota Commerce Commissioner Grace Arnold said during a news conference at the State Capitol on Wednesday. Employers of all sizes are bracing for higher health insurance costs. The Minnesota Council of Health Plans, a trade group for the state's nonprofit health insurers, said health care service use has accelerated significantly as medical cost inflation continues to outpace general inflation.
