Corporate Bitcoin treasuries have now topped 1 million BTC as more companies quietly and publicly build crypto reserves.

Reports show that from September 1 to September 6, companies announced fresh allocations of nearly 9,800 BTC — roughly 1 billion at current prices — pushing the corporate total past the seven-figure mark.

All-In On Bitcoin

Three new corporate treasuries appeared during the week. A Dutch firm opened with 1,000 BTC after raising about 147 million, according to crypto analyst @btcNLNico.

China-listed CIMG Inc started with 500 BTC, while US-based Hyperscale Data put in an initial 3.6 BTC via an early program.

Those new entries together accounted for about 1,503 BTC — small in headline size but important for the expanding roster of corporate holders.

Alongside those fresh entries, a broad set of firms added smaller but meaningful amounts. Mining and infrastructure companies chipped in:

Cipher Mining bought 195 BTC, CleanSpark added 124 BTC, and Convano and Cango took 155 BTC and 150 BTC, respectively.

Big Treasury Names, Big Appetite

These purchases were part of a larger pattern — 24 companies lifted holdings by about 8,339 BTC over the week. Spread across many names, these smaller allocations added real momentum to the dataset and highlighted wider participation beyond the marquee buyers.

Big treasury names kept buying, too. Michael Saylor’s Strategy made sizable buys that keep its total north of 636,500 BTC. Miner Marathon Digital added 1,838 BTC during the week, while Metaplanet purchased 1,009 BTC, pushing its stash past 20,000 BTC.

American Bitcoin increased its holdings by 502 BTC as part of a steady build. Those single-company moves made a substantial dent in the weekly total and underscored that both miners and non-miners are taking sizable positions.

Corporate activity was not limited to spot purchases. Several firms unveiled large purchase plans and funding approvals.

Metaplanet secured an expansion approval that could involve as much as ¥555 billion (about $3.8 billion). S-Science raised its buying limit to ¥9.6 billion (roughly $65.3 million). The Smarter Web Company agreed a subscription worth about £24 million (around $32.4 million).

A Growing Base

Meanwhile, Hyperscale Data plans to buy 20 million in Bitcoin through an ATM program and Convano pledged ¥2.5 billion ($17 million).

Other notable moves include Sora Ventures launching a 1 billion Bitcoin treasury fund, American Bitcoin preparing to list on Nasdaq as ABTC, and DDC Enterprise working with Gemini on treasury allocations.

Institutional flow also showed up in broader markets. BlackRock’s recent 290 million Bitcoin purchase was singled out among institutional moves, reflecting growing mainstream interest in building crypto exposure at scale.

The week’s story is both concentration and diffusion: a handful of massive treasuries keep growing, but dozens of smaller buys and new entrants are widening the base.

Together they pushed corporate Bitcoin holdings over the 1 million BTC mark — a milestone that shows companies are increasingly treating Bitcoin as part of corporate finance playbooks.
