The majority of this report was derived from the 2026 Midyear Devenir HSA Market Survey. This survey was conducted to shed light on the rapidly growing and evolving Health Savings Account (HSA) market. The survey was carried out in the summer of 2026, with data requested for the period ending on June 30th, 2026.

Key Findings

  • Asset growth remained strong as account growth picked up. At midyear 2026, HSAs held nearly $192 billion across 42.6 million accounts. Assets increased 20% year-over-year, while account growth accelerated modestly to 7%.
  • Investments became the majority of HSA assets. HSA investment assets reached $100 billion at midyear 2026, up 37% year-over-year and representing 52% of all HSA assets. About 4.7 million accounts, or 11% of all HSAs, held invested assets.
  • High-balance HSAs continued their long-term expansion. The number of accounts holding at least $10,000 reached 4.4 million, six times the level a decade ago. Nearly 1.9 million accounts now hold $25,000 or more, a fourteenfold increase over the same period
  • HSAs retained more than $11 billion in the first half of 2026. Account holders contributed $35.2 billion and withdrew $23.8 billion, retaining $11.5 billion during the period. Recently opened accounts remained particularly strong net contributors, with 2026 accounts contributing more than four dollars for every dollar withdrawn.

Devenir projects that the HSA market will exceed 49 million accounts and $246 billion in assets by the end of 2028.
