MARA PLEDGES 18,750 BTC FOR $600M AT 7.56% — 505MW OHIO GAS PLANT, MAINTENANCE-RATIO KEPT DARK
"MARA pledged 53% of its Bitcoin treasury — roughly $1.2 billion in BTC — as collateral for $600 million in new credit at a 7.56% weighted rate." — TFTC Newsdesk.
The Cap-structure read. MARA disclosed a $600M credit facility structured against 18,750 BTC pledged as collateral — 53% of the treasury stack. Counterparties: Coinbase Credit and Two Prime. Weighted rate: 7.56%. Use of proceeds: a 505MW natural-gas power plant in Ohio. The transaction is the miner-as-vertically-integrated-power-plus-compute-company thesis converting from slide-deck to cap-structure. The BTC is the collateral. The gas plant is the point.
The rate context. 7.56% weighted is inside the high-yield universe. Comparable unrated corporate credit at MARA's size would typically clear at 9-10% or higher without meaningful collateral. The BTC pledge takes ~200-250bps off the rate. That is the market's current pricing of Bitcoin as investment-grade-adjacent collateral, even without a rating. This is what BTC-as-collateral is starting to look like when it stops being theoretical.
The disclosure gap. MARA has not published the maintenance ratio — the BTC-price level at which the loan gets margin-called and the collateral gets forced into the market. This is the number the operator class needs, and it is the number MARA is keeping dark. Without it, a reader cannot model the second-order tail risk: how much BTC does the market absorb if MARA gets margined at $52K, at $48K, at $40K? A disclosure gap in a collateralized-loan structure is a decision. It's the wrong decision.
The thesis frame. This is the second half of the treasury-company thesis showing up in public. The first half was "buy Bitcoin with cheap capital" — Strategy's original wrapper move. The second half is "borrow against Bitcoin to buy the power and compute." MARA is not the only one running this play. Cleanspark, Riot, Hut8, Bitdeer are all somewhere on the same arc. The wrapper class is starting to look like a Bitcoin bank — not by title, but by mechanic. Treasury on the asset side. Secured lending on the liability side. Real assets as use of proceeds.
What to watch. (1) MARA follow-on 8-K in the next two weeks for the maintenance ratio — if it stays undisclosed past 30 days, treat that as a signal, not an omission. (2) Cleanspark and Riot's response — if either announces a similarly structured facility inside 60 days, the miner-as-bank arc is confirmed as a category, not a MARA-specific move. (3) Coinbase Credit balance-sheet disclosures next quarter — a $600M miner-backed loan is a real book event for their credit business.
THE MARA CREDIT, IN THREE LINES
STRUCTURE: 18,750 BTC pledged (53% of stack, ~$1.2B), $600M facility at 7.56% weighted, Coinbase Credit + Two Prime.
USE OF PROCEEDS: 505MW natural-gas plant in Ohio — vertically integrated power + compute.
DISCLOSURE GAP: maintenance ratio not published. Operator class needs it. MARA is keeping it dark.
