Riot Platforms’ Anthropic Deal: 20-Year Rockdale Lease, Bridge-Loan Timing Risk

The deal and the awkward timing

Riot Platforms locked in a 20-year lease for 191 megawatts of data-center capacity at its Rockdale, Texas campus with a high-profile AI tenant (widely reported as Anthropic). The lease is set up in two waves: the first 96 MW due in December 2027 and the remaining 95 MW expected by June 2028. Riot projects that initial payments from this deal could total roughly $9.1 billion through mid-2048, with options that could stretch the contract value even higher over time.

Sounds huge, right? Here’s the rub: Riot arranged an interim financing facility that lets it draw up to $573 million for early equipment and construction costs, but that bridge loan matures on December 31, 2026 — about a year before the first machines start producing rent. In plain English: Riot has temporary credit to get tools and dirt in place, but that loan expires well before the tenant actually starts paying.

The money, the risks, and what could happen next

The interim facility is a delayed-draw structure, which means Riot didn’t take the cash all at once; it has the borrowing capacity available as needed. The rate on the borrowings follows adjusted term SOFR plus 2.75%, or a defined base rate plus 1.75%, plus normal fees. The debt is secured mostly by the project’s assets and credit parties, and generally doesn’t come with full recourse to Riot Platforms itself.

But $573 million is just the opening act. Riot estimates the whole Rockdale buildout will cost between $2.1 billion and $2.3 billion. Their math assumes debt will finance roughly 80%–90% of that cost — so expect total project debt needs in a neighborhood of $1.7 billion to $2.1 billion. That means Riot will need to secure a longer-term financing backstop or another lender to take the baton before the bridge loan runs out.

What makes this interesting (read: nail-biting) is the timing and execution risk. The bridge gives Riot time to start work, but it also creates a hard deadline to line up substantial, investment-grade financing or other committed capital. If the replacement financing isn’t in place before the bridge matures, Riot could find itself racing to refinance or reshuffling project plans — neither of which is fun when big AI servers and concrete timelines are involved.

On the asset side, the disclosed collateral appears to be project-specific rather than a broad claim on Riot’s whole balance sheet. Riot also holds a notable stash of Bitcoin — roughly 11,380 BTC — which markets track closely, but the bridge’s primary security is tied to the Rockdale project itself.

Bottom line: this is a blockbuster long-term lease that turns into a short-term funding puzzle. If Riot nails the financing handoff, the company could be sitting on a very lucrative, multi-decade revenue stream. If not, the clock on that $573 million bridge could get uncomfortably loud.
