Medicare Advantage Plans Are Set to Collect $13 Billion in Quality Bonuses — UnitedHealth and Humana Lead the Queue

Who cashes in: UnitedHealth Group UNH runs the largest Medicare Advantage enrollment base in the country and historically captures the largest share of star-rating bonuses — more enrolled members in high-rated plans means more bonus dollars, which flow directly to operating income. Humana HUM derives roughly 90% of its revenue from Medicare Advantage and has been aggressively managing its star ratings; a strong bonus cycle is a direct earnings tailwind at a time when the company has been under margin pressure. CVS Health CVS through its Aetna subsidiary is the third major MA operator and benefits from the same dynamic, though its pharmacy and PBM businesses dilute the direct impact. Smaller pure-plays like Alignment Healthcare ALHC are higher-beta to the bonus cycle because MA is their entire business.

Who's exposed: Plans that slipped below four stars in the 2026 ratings cycle lose bonus eligibility and face a competitive disadvantage in the next enrollment period — members can and do switch plans based on star ratings. Centene CNC has historically had more exposure to lower-rated plans and Medicaid, making it less of a direct beneficiary of the MA bonus cycle. The broader risk is political: a $13 billion bonus payout to private insurers will attract scrutiny from both parties, and any CMS methodology change that tightens star-rating criteria would compress future payouts.

Watch the CMS final payment notice for 2027 MA rates, expected in early 2027 — that's when the next bonus cycle gets set. Any change to the star-rating methodology or bonus payment caps would be the most significant policy risk to this thesis.
