MARA’s Bitcoin stash fell 34% to under 36,000 BTC in H1

MARA Bitcoin holdings shrank sharply in the first half of 2026, leaving the miner with a smaller reserve balance as investors parse its latest quarterly reporting package.

MARA’s June 30, 2026 SEC filing and its second-quarter 2026 results release are the primary documents attached to this update, and the reporting tied to those materials points to the company’s treasury falling 34% to under 36,000 BTC in H1 2026.

What the current MARA documents establish

For a listed miner, held bitcoin is the portion of production the company kept rather than sold, so a move to under 36,000 BTC changes the balance-sheet signal attached to MARA’s latest results release.

That is why treasury moves at miners are watched closely. Coinlive’s recent coverage of Riot, MARA, and Nakamoto Bitcoin Sales in Q1: Full Breakdown and Bitcoin miners sold 15K BTC since October on hashprice slide shows reserve changes are already a live part of the sector discussion, and MARA’s H1 reserve figure adds another concrete data point.

What the evidence does not prove yet

MARA’s own documents support the fact of a smaller reserve, but they do not, on the face of the current filing and release, let this article pin the move on a single driver such as weaker production or a deliberate sale program. In treasury terms, mined BTC, sold BTC, and held BTC are different measures, and the June 30, 2026 filing is the anchor for the held-BTC figure used in this story.

Benzinga’s report on MARA’s Q2 highlights framed the quarter around bitcoin mining and AI power, which shows investors were also being asked to read the update as a broader operating report. That broader framing also lines up with Coinlive’s recent look at how Bitcoin miners diverge as AI pivot reshapes halving costs, while the reserve number itself still comes back to MARA’s company disclosure.

What readers should watch next

The next practical check is whether MARA’s next filing keeps holdings around the sub-36,000 BTC level or shows a rebuild after H1 2026. Because the headline move was 34%, the next disclosure matters more than any broader sentiment claim that falls outside MARA’s current company reporting.

Investors also need to read the reserve number alongside the rest of MARA’s official reporting, not in isolation. The company’s investor relations site, the Q2 2026 results release, and the related SEC filing are the authoritative places to watch for follow-through on this reserve change.
