Catalog BESTIES-v1, reviewed Oct 18, 2026. 38 relationships among 16 companies; 26 rest on SEC filings.

How to read it

Four kinds of dependence, one rule for evidence

Investment dependence

An investor, holder or guarantor puts capital or credit behind a company: shares, notes, warrants, guarantees. The investee relies on it; the investor is exposed to its value.

Customer dependence

A seller depends on a buyer. When OpenAI pays CoreWeave for capacity, CoreWeave has a customer dependence on OpenAI.

Supplier dependence

A buyer depends on a maker of chips, parts or wafers, as NVIDIA, AMD and Broadcom do on TSMC.

Infrastructure dependence

A company runs on another’s compute, cloud, data centers or power, as OpenAI does on Azure, AWS, Oracle and CoreWeave.

Evidence rule

A link is included only when an SEC filing or an official release of one of the two companies supports it, quoted word for word. Press reports and the post that inspired this tool are never enough. Confidence says which: filed with the SEC, stated by both companies, or by one. Excerpts are re-read every week where the site allows automated reads, and each source shows the date of its last check.

Materiality stays unknown unless stated

A deal size is not materiality. Boostio shows how much a relationship matters to a company only when a source says so, such as a filed revenue figure or a share of revenue. Everywhere else it says “unknown”; it never estimates a percentage.

Connected events

Every filing, and who it reaches

SEC filings of the 12 listed companies, last 120 days, checked Oct 23, 2026

When a company in the network files results, a material agreement or a financing, these are the companies directly tied to it on that date, through sourced relationships only. For a what-if (a spending pullback, a funding squeeze, a supply disruption or a value drop), pick the company on the map and open “What if”.

Research question

Do linked stocks react late to each other's news?

Collecting

A classic finding (Cohen and Frazzini, 2008) is that stock prices of suppliers did not promptly reflect news about their main customers. Whether that holds for this network today is unproven, so Boostio tests it forward, on paper, with rules fixed before the first event: LEADLAG-1. Collecting since Oct 19, 2026: day 4.

Events recorded

results or material agreements since the start

Measured

of 30 needed for a first read

Waiting for prices

five sessions must close first

Earliest read

Jan 17, 2027

and only with 30+ measured events

No statistic is shown before the read rule is met. Then the page will show the average delayed move of linked companies against the market and against unlinked peers, after costs, with its 95% interval, including if it is negative.

Events: 8-K results (Item 2.02) or material agreements (Item 1.01) from a listed company in the network, timed by the SEC acceptance time.
Linked companies: listed companies with a sourced relationship to the filer known before the filing; frozen when the event is recorded, never back-filled.
Measure: the filer's move on the event day (1% or more beyond the market), then each linked stock's move over the next 5 sessions in the same direction, beyond the market (SPY) and beyond unlinked peers, minus 0.12% of trading costs.
Paper research only: it opens no position and sends no alert. Amazon has no listed links in this network, so its filings are not part of the study.

Boundaries

What is not on the map, and why

The idea source, not evidence

An Instagram carousel arguing that investment into AI developers and their purchases from chip and cloud providers form circular funding dependencies, with shared downside if funding or demand slows. Instagram post by Derek and Dakota

Its network chart gives no source, date or size for any relationship and no legend for its arrows, and it ends by promoting the authors’ own business, not a trading system. Boostio used it as an idea only and rebuilt every link from primary sources.

Reported, but not confirmed by a primary source

NVIDIA invested $30 billion in OpenAI’s 2026 funding round. Reported by the press in March 2026. NVIDIA’s 10-K (February 2026) said it was still finalizing an investment and partnership agreement with OpenAI, with no assurance of completion, and its 10-Q for the quarter to July 26, 2026 names no OpenAI investment. OpenAI’s own announcement could not be read from Boostio’s server. Not shown until a primary source can be read.
Oracle’s large cloud contracts include about $300 billion from OpenAI. Press reports only. Oracle reports remaining performance obligations ($455 billion in its September 9, 2025 results) without naming customers, so no amount is attributed to OpenAI.
OpenAI and Broadcom agreed on 10 gigawatts of custom accelerators (October 2025). The October 13, 2025 release is on Broadcom’s investor site, which did not answer Boostio’s server, and OpenAI’s site blocks automated reads. The relationship is included from the June 24, 2026 joint release, which gives no amount.
Google owns a stake in Anthropic. No primary source reviewed here states it, and Alphabet’s 2025 to 2026 filings checked do not name Anthropic. Only the compute relationship is included.
Other verified AI compute deals, such as Anthropic’s May 2026 agreement to use SpaceX’s Colossus 1 data center or CoreWeave’s contract with Jane Street. Outside this first network, which covers the funding and compute circle around OpenAI and Anthropic. They are left for a later version.
The idea source’s revenue, IPO timing, valuation, crash-analogy and "fake demand" claims. Not verified (see the review of the post). Capital that circulates between investors, AI developers and suppliers is not by itself evidence of fake demand or wrongdoing.

Method and data

Rules written before the first run

Sources

SEC EDGAR filings (10-K, 10-Q, 8-K and exhibits, S-1) and the companies' own newsrooms. 37 sources, each read in full; the excerpt that supports a link is stored word for word and searched again every week. A changed source is flagged and waits for a reviewed catalog version.

Events and prices

Filing events come from SEC EDGAR, timed by the acceptance time on each filing's index page. Daily closes for the forward study come from Nasdaq.com, counted only once final (8 pm New York). Prices through Oct 22, 2026.

What it is not

Not a trading system, not a forecast and not advice. Exposure means a sourced connection, not a predicted loss. No broker, no order, no position, no real money. Rules: BESTIES-v1 and LEADLAG-1, versioned and dated.

Questions

Stock Besties, answered

What is Stock Besties?

A research map of business dependencies in the AI build-out: who invests in whom, who buys from whom, who supplies whom and who runs on whose data centers. Every link is backed by an SEC filing or the companies’ own releases, shown with a verbatim excerpt, its date and a link.

How is it different from Stock Trade Twins?

Stock Trade Twins looks for rival stocks whose prices move together. Stock Besties maps companies that depend on each other’s business. The two questions are separate: a business link is not price correlation, and a price relationship says nothing about who depends on whom.

If two companies are linked, will one stock follow the other?

Not necessarily. Economic linkage is not a promise that prices move together or converge. Whether linked companies react to each other’s news with a delay is an open research question: Boostio is measuring it forward from October 19, 2026 (LEADLAG-1) and shows no statistic until there are at least 30 measured events and 90 days of evidence.

Does money going in circles mean AI demand is fake?

No. Investment-funded purchases are legitimate business, and capital moving between investors, AI developers and suppliers is not evidence of fake demand or wrongdoing. The map shows it as what it is: shared exposure, where trouble at one company would reach the others through sourced relationships.

Why do OpenAI and Anthropic have no ticker?

They are private companies. They appear as information nodes so their partners’ exposure is visible, but they have no listed shares, so Boostio shows no price or market value for them and they cannot be picked as holdings.

How much does each relationship matter?

Only as much as a source says. When a filing states a share (for example, CoreWeave reporting that Microsoft was about 67% of its 2025 revenue) Boostio quotes it; otherwise it says "unknown". Boostio never estimates exposure percentages.

Related: Stock Trade Twins, rival stocks whose prices move together, and the AI Bottleneck Radar, where the AI build-out could run short. Companies: OpenAI, Anthropic, Microsoft, Amazon, Alphabet (Google), Oracle, CoreWeave, SB Energy, Meta Platforms, NVIDIA, AMD, Broadcom, Intel, Micron, TSMC, SoftBank Group.
