Should You Enroll in Medicare in 2026?

Individuals turning 65 in 2026 can enroll in Medicare beginning three months before their birthday; Part A is typically premium-free while Part B carries a monthly premium. The piece notes that those with employer-sponsored group coverage (generally plans with 20+ employees) or active HSA contributions may benefit from delaying Medicare to avoid losing HSA contribution eligibility and potentially incurring late-enrollment penalties, and reminds readers that HSAs convert to IRA-like treatment for non-medical withdrawals after age 65.

Analysis

Market structure: Short-term behavioral shifts (many 65-year-olds delaying Medicare enrollment to keep HSA contributions) favor HSA custodians/asset managers (e.g., HealthEquity HQY) and employer-plan insurers that retain premium-paying members. Medicare Advantage incumbents (UnitedHealth UNH, Humana HUM, Elevance ELV) keep long-term demand from aging demographics, but marginal MA membership growth could be damped over the next 12 months, pressuring near-term enrollment-driven revenue recognition. Pricing power shifts to custodians and asset managers who capture recurring fee income on rising HSA AUM; small supplemental insurers face slower intake.

Risk assessment: Tail risks include legislative moves to curtail HSA tax benefits or expand Medicare buy-in—either would be high-impact within 6–18 months; operational risks include employer-plan redesigns that change the 20-employee exemption and trigger enrollment waves. Immediate (days–weeks): watch year-end enrollment deadlines (Dec 31 window) and Q4 guidance; short-term (3–12 months): AUM/membership trends; long-term (1–5 years): secular aging supports MA and HSA demand. Hidden dependency: employer size thresholds and corporate benefit strategies are the gating variables that create lumpy flows.

Trade implications: Direct plays—overweight HQY (HSA AUM sensitivity) and selective MA names (UNH/HUM) where MA penetration remains >30% and combined ratio risk is manageable; underweight small-cap Medicare supplement writers (e.g., CNO Financial CNO). Options: use 9–12 month calls on HQY/UNH to express upside with limited capital, or buy protective puts on small-cap supplement names. Entry: initiate positions now–Q1 2026; exits or rebalancing on quarterly AUM membership beats/falls >5% q/q or any legislative proposal within 30–90 days.

Contrarian angles: Consensus underappreciates that marginally delayed Medicare enrollment boosts taxable payroll deferral benefits and HSA AUM growth for 12–36 months, not just a one-quarter effect—this underprices HQY-like custodians. Conversely, MA names are priced for uninterrupted membership expansion; a 2–4% shortfall in new enrollees over the next year could compress forward multiples 5–10%. Historical parallel: prior policy noise in 2018–2020 created temporary sentiment drawdowns but sustained secular tailwinds restored multiples; watch for unintended employer benefit shifts that could reverse the trade.

Key Decisions for Investors

• Initiate a 2.5% long position in HealthEquity (HQY) now with a 9–12 month target upside of 20–30% if HSA AUM growth >5% quarter-over-quarter; set a 12% stop-loss and add half-size on two consecutive AUM beats.
• Allocate a 2–3% core long split (1.25% UNH, 1.25% HUM) targeting +15% in 12 months; use 12-month calls (≈25% out) if seeking leverage and implement an 8% cash stop-loss on the equity leg.
• Establish a 1.5% pair trade: long HQY (1%) / short CNO Financial (CNO) (0.5%) expecting CNO membership flow weakness; close pair if CNO outperforms by >7% relative or HQY AUM growth misses by >5% q/q.
• Rebalance sector exposure: reduce small-cap Medicare supplement and hospital-focused healthcare exposure by 3–5% and rotate into HSA custodians and MA leaders through Q1 2026; re-evaluate after Q1 earnings or any congressional HSA reform proposal within 30–90 days.
