**Proposition 44 would require nonprofit federally qualified health centers to spend at least 90 percent of revenue on program services and patient care, with penalties redirecting shortfalls to state accounts.** The measure, sponsored by SEIU-UHW and qualified via petition signatures for the November 3, 2026 ballot, faces coordinated opposition from the California Primary Care Association and other clinic groups. These opponents highlight independent analyses projecting up to $1.7 billion in first-year penalties, potential clinic closures or service reductions, and claims that the rules conflict with federal funding requirements. A federal lawsuit alleging preemption remains active, while major medical associations have aligned against the initiative. Traders assign a 73 percent implied probability to rejection, reflecting these structural and institutional barriers more than polling data at this stage.
