More Americans Can Contribute to an HSA Under the OBBB -- Are You Eligible?

The 2025 tax bill (the OBBB) expanded Health Savings Account (HSA) eligibility effective Jan. 1, 2026, making ACA Marketplace Bronze plans and about 54,000 catastrophic plans HSA-compatible and allowing certain direct primary-care arrangements to qualify. High-deductible thresholds remain defined for 2026 ($1,700 individual / $3,400 family); Bronze plans comprised roughly 30% of 2025 Marketplace selections, and the White House estimates the changes could add about 3 million newly eligible people (raising additional HSA-eligible plans to 10 million). The rule change could materially broaden the base of HSA accounts and associated investable balances, benefitting HSA custodians, wealth managers, and healthcare finance participants over time.

Analysis

Market structure: The OBBB expansion converts a large tranche of ACA Bronze/catastrophic enrollees into HSA-eligible users, creating direct beneficiaries: HSA administrators/custodians, asset managers, and payroll processors. Conservative estimate: +3M new accounts could translate into $5–20bn incremental investable HSA assets over 1–3 years, boosting fee income for specialists while shifting short-term deposits away from legacy regional banks.

Risk assessment: Key tail risks are regulatory reversal or adverse IRS guidance within 30–180 days, and weak consumer take-up (if <30% of newly eligible enroll), which would cut flows materially. Near-term market reaction likely muted (days-weeks); the meaningful revenue cadence appears over 2–12 quarters as enrollments convert and custodial partnerships are signed.

Trade implications: Direct plays favor publicly listed HSA/platform providers (HealthEquity HQY), big custodians/asset managers (SCHW/BLK) and payroll processors (ADP/PAYX); insurers selling Bronze plans (CNC, ANTM, UNH) see modest premium tailwinds. Options: use 3–9 month call spreads on HQY/SCHW to capture accelerating fee flows while limiting downside.

Contrarian angles: Consensus assumes full monetization; reality depends on employer integrations and consumer behavior—many HSAs remain cash-only. Historical parallels (401(k) auto-enrollment rollouts) show slow but persistent asset accumulation over multiple years; short-term mispricings likely in small custodial competitors and regional banks exposed to deposit outflows.

Key Decisions for Investors

• Establish a 2–3% long position in HealthEquity (HQY) with a 12-month target +25–35% and stop-loss at -12%; complement with a 6–9 month call spread (debit spread) to lever upside while capping premium risk.
• Add a 1–2% core position in UnitedHealth (UNH) for 12–24 months to capture Optum distribution/banking synergies; trim if management fails to announce HSA product rollouts or partnership wins within 90 days.
• Initiate a 1% long position in ADP (ADP) or PAYX for exposure to increased payroll-deduction flows, with a 6–12 month horizon; consider buying 3–6 month calls if implied vol is low (<25%).
• Implement a relative-value pair: long HQY (2%) / short KRE (SPDR Regional Banks ETF) (1%) for 6–12 months to express custody/fee winners vs. regional bank deposit pressure; if HQY quarterly 'new accounts' >500k or 'total HSA assets' growth >10% QoQ, scale long to 4%.
• Monitor IRS/DoH guidance and Q1–Q2 2026 filings: if federal guidance clarifies implementation windows beyond Jan 2026 or enrollment adoption lags (new HSA activations <200k in first quarter), reduce exposure to custodial plays by 50% within 30–60 days.
