Costco Is Getting Into Medicare — Here’s What Its New Health Insurance Plans Could Mean for Seniors

Aug 18, 2026, 12:48 PM UTC · Primary ticker $COST

Costco is expanding its services by partnering with SCAN Group to offer co-branded Medicare Advantage and Medicare supplement plans in a limited rollout. This move diversifies Costco's revenue streams and leverages its brand recognition to enter the competitive healthcare market, potentially impacting existing Medicare Advantage providers.

Costco is making a strategic move into the Medicare insurance market through a partnership with SCAN Group, initially offering co-branded Medicare Advantage and supplement plans in a limited number of states. This represents a significant diversification for Costco beyond its traditional retail and ancillary services, aiming to leverage its strong brand loyalty and potentially integrate with its existing offerings like prescription drugs and vision. For Costco, this is a long-term opportunity to tap into the large and growing senior healthcare market, potentially boosting membership engagement and revenue. For incumbent Medicare Advantage providers like Humana, UnitedHealth, and CVS Health, this introduces a new, well-capitalized competitor, adding pressure to an already scrutinized market facing rising costs and regulatory changes. The short-term impact on these incumbents might be minimal due to the limited rollout, but long-term, it signals increased competition and potential market share shifts.
