California High-Speed Rail needs $126 billion to connect San Francisco to Los Angeles. It has $39.3 billion.
That’s an $87 billion hole, and the authority’s 2026 business plan doesn’t pretend otherwise. Its only guaranteed money is a state commitment of $1 billion a year through 2045 from cap-and-invest. Meanwhile the Federal Railroad Administration, under Secretary Sean Duffy, terminated roughly $4 billion in unspent federal grants.
So the authority is doing what everyone eventually does. It’s calling investors.
A $25 million agreement to look for money
In late June the authority signed a co-development agreement with a consortium of high-speed rail, infrastructure and investment firms, referred to as Momentum Alliance Partners. The deal is worth $25 million over an initial 30-month term. The consortium spends the next six months “identifying viable strategies” to fund construction beyond the current 119-mile Merced-to-Bakersfield phase.
An authority spokesman called it a partnership “to evaluate accelerated delivery, private investment, and public partnership opportunities.”
Baruch Feigenbaum of the Reason Foundation reads it differently, calling the arrangement “a standard engineering contract paid for by taxpayers.” His broader objection is harder to dismiss: “If they could have gotten private sector investment, they would have gotten it already.”
The private model isn’t going well either
The counterexample was supposed to be Brightline West, the 200-mph Las Vegas-to-Southern California line backed by Fortress Investment Group. Private money, private discipline, no federal dithering.
Its projected cost went from $12 billion to $21.5 billion. Completion slipped from 2028 to 2029. It promised to raise $400 million by March 31, 2026 and didn’t. Las Vegas station work is underway; most of the rest of the alignment is still geotechnical borings, utility potholing and land surveying.
Brightline Florida, from the same sponsor, faced default if it couldn’t restructure debt obligations due July 1, 2026.
Alon Levy of NYU’s Marron Institute is skeptical of the whole framing: “Private-sector plans aren’t really workable, and I expect Brightline West to pivot to expecting even more federal funds.” His structural point is the one that should worry investors. Private infrastructure deals are usually built to limit the downside and keep the upside. Governments won’t bail out a railroad that doesn’t turn a profit, so the downside here is real.
What actually got built this year
Track installation at a Kern County railhead staging hub is complete. The authority approved installation of track, overhead contact system, train control and communications along the 119-mile Central Valley segment. It opened an RFQ to extend the line to Madera, a $2.4 billion job.
That is genuine construction, and the Central Valley segment will carry trains. The question was never whether California can build 119 miles of railroad. It’s whether anyone will pay for the 400 miles that make it useful.
Florencia Cirigliano of RedCoach summed up the moment: “Brightline deserves credit for trying, but the challenges they’re facing aren’t surprising. I think what we’re seeing now is reality catching up with ambition.” The authority’s release has the consortium details. For a transit project that did finish, see CTA’s RPM Phase One, delivered for $2.1 billion with a signed federal grant agreement behind it.
