Methodology
Data coverage & methodology
How CorpStacking sources, reads, and verifies corporate Bitcoin, Ethereum, and Solana treasury data.
We publish this page so you can audit us before you trust us. Treasury data has a credibility problem — aggregators go stale for weeks, mistakes quietly overwrite real holdings, and nobody shows their work. The sections below trace every number on the site back to its primary source and disclose every known limit. If we’re wrong about an entity, you should be able to tell from this page how to spot it.
Methodology last reviewed 2026-05-23
179 public companies · 58 ETFs · 32 private companies · 9 governments. 93 entities cited to SEC EDGAR filings. Cross-source reconciliation < 1h ago.
Sources
We split sources by role. Primarysources are legally authoritative — SEC filings, government press releases, official company disclosures. Cross-check sources are third-party aggregators we reconcile against daily. When the two disagree, the primary source wins and we document the divergence on the entity page.
| Role | Source | Cadence |
|---|---|---|
| Primary | SEC EDGAR | Near real-time |
| Primary | Company IR & press releases | Event-driven |
| Primary | Government & agency press releases | Event-driven |
| Cross-check | bitbo.io | Daily |
| Cross-check | CoinGecko public treasury | Daily |
| Pricing | Licensed equity market data | Real-time |
| Pricing | Token price reference | Daily |
| Sentiment | alternative.me | Daily |
| Sentiment | cfgi.io | Near real-time |

Per-event data sources
Each entity carries a small coverage badge next to the ticker showing where the per-purchase data comes from. Some companies file every move with the SEC the same day; others disclose quarterly, by press release, or only through aggregators. The badge tells you which one applies before you read the numbers.
Wallet ingestion. Every transfer is visible at the block level with a transaction hash. The gold standard for self-custodied crypto-native treasuries.
Three or more SEC event filings parsed. Every purchase links directly to its official SEC filing. Audit-grade, near-real-time coverage for US public companies.
Official quarterly and annual balance disclosures filed with the SEC. Per-quarter holdings are authoritative; we derive per-event detail by comparing successive filings.
Discrete purchases announced via BusinessWire / Globe Newswire / PR Newswire and manually cited. Common for ETH/SOL treasuries that disclose through investor-relations channels rather than standalone SEC event filings.
Holdings figure from a third-party aggregator (CoinGecko, bitcointreasuries) with no per-event audit trail. Common for international entities, governments, and small private holders. Use the “Verified events only” filter on the leaderboard to hide these.
Entity is tracked by ticker but no holdings or events are currently sourced. On the list for future backfill.
Tiers auto-upgrade. The moment an entity flips from press release to full SEC coverage, the badge follows. The classifier runs every night against the live data so this is never manually managed.

Primary sources take precedence over aggregators
Daily cross-source reconciliation
- Within 5% — consistent; no change.
- 5–10% drift — flagged for operator review.
- Greater than 10% — escalated for same-day review.

Per-token coverage breakdown
Every active holding is classified daily based on how many independent references agree with our number. The same classification is exposed on the public treasuries API for programmatic access. Numbers below are live from the most recent run.
| Token | Verified 2+ references agree | Strong 1 reference agrees | Primary only no third-party reference | Pending awaiting first check |
|---|---|---|---|---|
| BTC(232) | 66 | 76 | 73 | 17 |
| ETH(38) | 14 | 17 | 6 | 1 |
| SOL(29) | 10 | 13 | 4 | 2 |
“Primary only” is not lower confidence in our number. It means the entity is confirmed by a primary filing (SEC, sponsor disclosure, IR release) but no third-party aggregator covers it — common for foreign-listed issuers, recent IPOs, and small-cap entities. Pending means the daily reconciliation hasn’t produced a verdict yet, typically because the entity was added in the last twenty-four hours.
References used. Bitcoin reconciliation draws on bitbo, CoinGecko, and bitcointreasuries.net. Ethereum and Solana reconciliation draws on CoinGecko. The 5% agreement threshold accommodates intra-day price moves and reference-snapshot lag without ignoring real drift.
Recently verified against SEC filings
The most recent disclosures ingested into the dataset, one row per entity. Some filing dates may be historic — those reflect backfills where the entity was added or re-verified recently. Every accession number is live in SEC EDGAR; copy any one of them into the EDGAR full-text search to verify the filing yourself.

What we don’t claim
Three categories of data have inherent limits. We surface them rather than paper over them.
Government holdings are inherently approximate
Government entities are sourced from court filings, DOJ press releases, and on-chain wallet attribution. We cross-check against bitcointreasuries.net and Arkham, but none of these are audited balance sheets — sovereign accounting for seized Bitcoin is opaque by design.
Foreign-listed companies may show dashes for debt and cash
Non-US issuers (Metaplanet, Sol Strategies, Phoenix Group, and similar) may render dashes in the debt-to-token and cash columns. Our equity-data providers cover US venues comprehensively but not every foreign exchange. When we can't independently verify a balance-sheet line item, we render a dash rather than publish a number we can't stand behind.
Aggregators sometimes disagree
When two third-party aggregators disagree, or when our SEC-derived figure diverges from both, we surface our primary-source figure and document why on the entity page. The /treasuries/[slug] page links the filing so you can verify in one click.
Pre-2020 holdings have approximate purchase dates
Companies that disclosed Bitcoin holdings before we began reading SEC filings live (most of pre-2020) have aggregate holdings verified against current filings, but individual purchase-by-purchase timelines may use approximate dates. Affected rows are flagged as estimated in the public API and labelled accordingly on the entity page so you can tell at a glance which dates come from the original filing versus a reconstructed period-end balance.
