California high-speed rail authority faces cash exhaustion by December 2027, inspector general warns

California's high-speed rail project - the 171-mile Merced-to-Bakersfield corridor under active construction in the Central Valley - could exhaust all available funding by December 2027, according to a July 31 report from Inspector General Benjamin Belnap^[1]. The warning, addressed to the governor and legislative leaders, lands as state lawmakers face an end-of-session deadline of 31 August to begin addressing the shortfall.

A $9.5 billion gap that peaks before the money arrives

The High-Speed Rail Authority has identified $39.3 billion in total long-term funding for the Merced-to-Bakersfield segment, including $1 billion annually from the state's Cap-and-Invest program through 2046. The problem is timing: those revenues arrive too slowly to cover expenses during peak construction years, leaving the authority facing a $9.5 billion financing gap between fiscal years 2027-28 and 2031-32^[1].

The immediate cliff is steep. The authority would need $2.2 billion in fiscal year 2027-28 alone to keep construction on schedule, according to the OIG's review of the authority's own cash-flow analysis. To bridge the gap, officials are weighing internal state borrowing, revenue-backed bonds, and private financing - but each option carries a cost the authority has not publicly foregrounded. Borrowing would add between $3.6 billion and $6.6 billion in interest charges, none of which are included in the authority's official $35.7 billion cost estimate for the segment.

The inspector general also flagged a second, fuller cost figure buried in a risk-management appendix rather than the business plan's main cost section: $47.7 billion - roughly $12 billion above the headline estimate - once financing costs and a roughly $1.7 billion settlement with the city of Shafter are included.

Schedule slippage the business plan did not clearly disclose

The funding crisis compounds a schedule problem the OIG says the authority has not adequately communicated. Between August 2025 and March 2026, the Merced-to-Bakersfield construction schedule slipped nine months. The authority's internal statistical risk analysis - which it is required to conduct - identified September 2034 as the 65th-percentile confidence date for completing the segment, meaning there is only a 65% probability of finishing by that date under current conditions.

The authority's CEO letter in the 2026 Business Plan still described the project as on pace for completion "in 2032-2033." The OIG found that framing "could mislead stakeholders about schedule risk," given that the authority's own risk model had extended the window to 2034. Even that date, Belnap noted, assumes legislative actions outside the authority's control.

Federal funding gone, train contract still unsigned

The cash-flow problem is inseparable from the collapse of federal support. The Federal Railroad Administration terminated approximately $4.2 billion in federal grants in July 2025, citing nine compliance failures including missed deadlines, budget shortfalls, and the authority's failure to execute a trainset procurement contract. The Trump administration declared there was "no viable path" to completion.

California sued to reverse the decision, but the state quietly dropped the lawsuit on 23 December 2025 - two days before Christmas, with no press release - after the authority missed a second self-imposed deadline to execute the train contract that it had promised in sworn federal court filings.

As of early August 2026, no trainset contract has been executed. The authority's procurement page lists the award date as "to be determined." In an 6 August procurement notice, the authority confirmed it had modified the contract to remove provisions that had been federally required - and cut the initial order from six trainsets to three.

The authority disputed the inspector general's findings in a written response included in the report, saying they reflect "differences in interpretation rather than gaps in information." The OIG stood by its conclusions.

What to watch

California lawmakers must act before the 31 August legislative session deadline to begin addressing the financing structure. The authority says it will provide more detail on funding options in its 2027 Project Update Report. Whether the state can borrow against future Cap-and-Invest revenues - similar to how New York's congestion pricing program enables its transit authority to leverage future income - will be the central question. Until a financing mechanism is locked in and a trainset contract is signed, the December 2027 cash deadline remains the project's most immediate construction risk.
