Tesla lines up $30B in credit from Citibank and Wells Fargo to scale Cybercab, Optimus and Semi

Tesla has arranged $30 billion in fresh credit lines, money the company says could support the scale-up of the three programmes now sitting at the centre of its roadmap: the Cybercab robotaxi, the Optimus robot and the Tesla Semi.

The financing, in pieces

According to TechCrunch, Tesla announced the package on Tuesday. Citibank has agreed to a $20 billion term loan facility with a three-year term, structured as a delayed-draw deal — meaning Tesla can take the funds down in stages over the life of the agreement instead of receiving the full amount on day one. Wells Fargo supplies the remainder through two revolving facilities: an $8 billion line running five years and a $2 billion line with a 364-day term.

The structure splits the commitment across horizons. A term loan locks in long-dated funding capacity, while revolvers behave more like corporate credit lines, letting a borrower draw, repay and redraw within the limit while the facility stays open.

Nothing gets drawn this year

TechCrunch reports that Tesla told regulators in a filing that it does not plan to tap any of these facilities before the year is out. That frames the arrangement as standby capacity rather than money the company needs immediately.

The wider financial picture explains the buffer. Tesla has already guided to capital expenditures of at least $25 billion for 2026, and it finished the second quarter carrying roughly $9 billion in debt against more than $40 billion in cash and investments. The new lines therefore add committed borrowing capacity that, on its own, exceeds the company's stated capex plan for the year — and they do so while Tesla is still funding its spending from a cash-rich position.

Factories behind the products

Each of the three programmes brings heavy manufacturing demands. TechCrunch notes that all three products have required new production lines, and that for the Semi and the Optimus robot, Tesla has gone further and built out entirely new dedicated factories.

That distinction matters. New lines inside existing plants are one order of cost; stand-alone factories — construction, tooling, staffing — are another, and they are typically where industrial-scale capital spending concentrates. The Optimus programme in particular implies tooling up for a product category with no established mass-production playbook.

Why it matters

The size of the commitment is the headline. Thirty billion dollars in fresh credit, arranged while the company already holds more than $40 billion in liquid assets, signals that Tesla expects its next wave of spending to be unusually large and sustained — and driven not by the existing car business but by autonomy and robotics.

For the broader AI sector, the deal underlines that moving from working prototypes to volume production is a financing problem as much as an engineering one. Robotaxis and humanoid robots need factories, supply chains and tooling built at industrial scale, and tens of billions in committed bank credit is what underwriting that transition looks like.

It also gives Tesla room to absorb cost overruns or delays across the Cybercab, Optimus and Semi programmes without having to raise capital on short notice. Whether those bets pay off remains unproven, but the company now has the cash pile — and the credit — to keep building while it finds out.
