California High-Speed Rail Faces December 2027 Funding Risk

USA: California’s high-speed rail project could exhaust the cash needed to stay on its planned Merced–Bakersfield construction schedule by December 2027 unless financing is secured, according to the project’s inspector general.

The warning is primarily a cash-flow timing problem rather than a finding that the project has no long-term revenue. The Inspector General’s review says the Authority has identified $39.3 billion in available funding, including a fixed $1 billion annual Cap-and-Invest appropriation authorized through 2045, while its reduced-scope Merced–Bakersfield estimate is $35.7 billion.

Peak construction spending arrives before much of that future revenue. An Authority cash-flow schedule provided to the Office of the Inspector General shows a $2.198 billion funding gap in fiscal year 2027–28 and a cumulative $9.556 billion gap through 2031–32 if the project follows the planned spending schedule.

Funding Gaps Total $9.56 Billion Through 2031–32

The Inspector General published the following cash-flow schedule, with figures in millions of dollars:

Without financing, the Authority’s pay-as-you-go scenario would postpone the start of the Merced extension to fiscal year 2032–33 and the Bakersfield extension to fiscal year 2038–39 so annual Cap-and-Invest revenue could accumulate. Those dates are a modeled scenario, not a confirmed construction schedule.

The funding pressure comes after the project lost about $4 billion in federal support. The Authority’s current funding structure therefore relies heavily on state sources while it explores ways to convert future revenue into capital available during the peak construction years.

Three Financing Paths Add Billions in Modeled Costs

The 2026 Business Plan considers three broad approaches to bridge the timing gap: borrowing from internal state resources, issuing revenue bonds backed by future revenues, or using private-sector financing. The Inspector General says none of the modeled options is cost-free and that potential financing costs are not included in the Merced–Bakersfield capital estimate.

The revenue-bond and private-financing models assume the Authority finds additional revenue that has not yet been identified; the Inspector General says financing costs could be higher without it. Revenue bonds would also require non-impairment language in state law and an opinion from the California Attorney General that the Authority is eligible to use them.

Private investment is also still prospective. The Authority’s June 2026 co-development agreement with Momentum Alliance Partners is evaluating private investment and public-private partnership structures for future expansion beyond the active Merced–Bakersfield segment; it is not a disclosed commitment to cover the December 2027 cash-flow need.

In its response to the Inspector General, the Authority said financing costs depend on future policy choices, including how much is borrowed, when borrowing occurs and which mechanism is authorized. The near-term issue is therefore not only how much long-term revenue the project has, but whether California can put a financing mechanism in place soon enough to keep that revenue available when construction bills come due.
