Research notes across crypto equity, filings, insider activity, ETF wrappers, and market context, written from the records outward.
Susan Li, Javier Olivan, and Andrew Bosworth all filed S-code sales between May 15 and May 18, 2026. That is not a single-officer filing. That is a cluster.
Todd Duchene's $231,000 Form 4 cluster at Core Scientific is small against a stock up 59% year to date and reads as ordinary disposition near a local high.
Five senior insiders filed F-code transactions on the same day. That is vesting mechanics, not anyone's view on the stock.
ORCL filed a May 12 Item 7.01 disclosure as the stock claws back from an April low. The timing points to an investor communication, not a surprise.
Todd Duchene's May 11 Form 4 filing shows a modest S-code sale against a stock that has more than doubled in a year.
Frederick Thiel and Zabi Nowaid each filed Form 4s on May 18, and the transaction code tells most of the story.
A same-day Form 4 cluster from three MARA insiders totals about $621,000, a modest sum against the company's recent 90-day run.
Director Jarrod Patten filed two S-coded Form 4 transactions on May 14, totaling roughly $286,000 in proceeds, a small cluster that fits his established selling cadence rather than signaling a directional view.
A 21-transaction Form 4 cluster at ServiceNow on May 15 is wide in headcount but narrow in mechanics, pointing toward compensation-linked tax withholding rather than discretionary selling.
Tien Bor-Zen filed a P-code purchase at TSM on May 19, a discretionary open-market buy made while the stock sat within striking distance of its recent peak.
Spot ETF wrappers, treasury holders, miners, and exchanges each carry different risk structures, and treating them as interchangeable Bitcoin beta obscures the most important information in their filings.
ARK 21Shares Bitcoin ETF filed an 8-K disclosing entry into a material definitive agreement, a structural event that deserves more attention than the fund's flat short-term price action suggests.
ARK 21Shares Bitcoin ETF filed its inaugural 10-K on March 26, 2024, covering the year ended December 31, 2023, and the document set the disclosure baseline for a product category that had no annual-report precedent.
ARK 21Shares Bitcoin ETF filed its June 2024 quarterly on August 9, 2024. The filing matters for what it codifies about spot Bitcoin ETF wrappers, not for any period metric.
ARK 21Shares Bitcoin ETF filed its June 30 quarterly report on August 13. The filing is the floor of disclosure. The real ARKB story sits in peer flows and Bitcoin price.
ARK 21Shares Bitcoin ETF filed its quarterly report in November 2025. The document's value is in what it reveals about how spot Bitcoin ETF wrappers get tracked, not in financials that do not exist.
The ARK 21Shares Bitcoin ETF filed its 2025 annual report in March. The document is thin by design and useful as a category baseline.
ARK 21Shares Bitcoin ETF filed its March 31 quarterly report on May 8. The filing is simpler than most 10-Qs in the Bitcoin-equity universe by design.
Four categories, four tapes. The treasury holder is flat on the month, the exchange is down sharply, the miner leads the 90-day, and the ETF wrapper tracks Bitcoin tight.
CEO Lisa T. Su and director Paul Darren Grasby filed 23 Form 4 sales between May 8 and May 13, totaling roughly $66.52 million.
Riot Platforms filed its fiscal 2025 annual report with the equity nearly tripled off its 52-week low. The operating leverage story lives or dies on what the filing says about power economics and production capacity.
The accounting rule change effective for fiscal years beginning after December 15, 2024 forces a hard distinction between treasury holders, miners, exchanges, and ETF wrappers that most investors still treat as interchangeable Bitcoin beta.
CLSK's May 10-Q puts $813.22 million of Bitcoin on the books as of March 31. The miner underneath is still 44% below last October's high.
IBIT, FBTC, and ARKB created a clean Bitcoin benchmark. That benchmark forces every miner, treasury holder, and exchange to justify what they add on top.
