California is facing another massive budget shortfall tied to its ambitious expansion of Medi-Cal, the state’s healthcare program for low-income residents. Governor Gavin Newsom’s administration initially projected the cost of providing coverage to undocumented immigrants at $3.5 billion, but that number has ballooned to $8.5 billion annually—a staggering $5 billion miscalculation.

In a year when California’s budget is already stretched thin, Newsom’s administration plans to borrow $3.4 billion from the state’s general fund to cover unexpected costs. What remains unclear is how or when the state intends to repay that money.

The state attributes the budget shortfall to higher-than-expected enrollment in Medi-Cal and underestimating the costs associated with expanding coverage to undocumented immigrants. While the aim of providing healthcare access to vulnerable populations is commendable, the financial reality is shaping up to be much more complicated than lawmakers initially anticipated.

With nearly 15 million people now enrolled in Medi-Cal, the program has become one of the largest expenditures in California’s budget. Expanding coverage to undocumented immigrants, a move championed by some California lawmakers was sold as a manageable cost—but the revised budget figures now paint a different picture.

The administration’s decision to pull $3.4 billion from the state’s general fund raises serious concerns about long-term fiscal responsibility. Unlike a temporary emergency expense, the Medi-Cal expansion represents a permanent cost that will continue growing as more people enroll. Borrowing from the general fund may plug the hole this year, but what happens when the next shortfall arises? Will California continue raiding other budget areas or eventually cut services elsewhere to compensate?

The sharp increase in Medi-Cal costs comes as California struggles with budget deficits and economic uncertainty. The state has been forced to slash spending in other areas, including infrastructure and public safety, while pushing for costly social programs.

As Newsom’s administration scrambles to cover the unexpected costs, lawmakers must grapple with a difficult question: How much can California afford to spend on programs that serve an unlimited number of people, regardless of legal status, without jeopardizing other essential services?
