Zero of 83: The Superinvestors Aren't in IREN

October 8, 2026

GetCoattail Research — IREN is the market's loudest AI-infrastructure story: a $9.7 billion Microsoft contract, an NVIDIA partnership, analyst targets near twice the price. We ran it through every filing lens we maintain. The cohorts whose buying usually validates a story like this are not there — and that absence, measured precisely, is the story.

Start with the narrative, because it is a good one. IREN, the former bitcoin miner Iris Energy, is rebuilding itself as an AI cloud. It signed a five-year, $9.7 billion GPU cloud contract with Microsoft in November 2025, deploying NVIDIA GPUs at its Childress, Texas campus — and a $3.4 billion AI cloud agreement with NVIDIA itself. Management targets more than $4 billion of contracted annual recurring revenue operational by the end of December 2026, against roughly $1 billion operating in late August. JPMorgan flipped from underweight to overweight in September 2026 and raised its target to $65; published consensus averages sit between roughly $78 and $81. The stock trades around $40 in early October 2026, with a market value near $16.4 billion.

Now the filings. GetCoattail tracks the portfolios, trades and disclosures of the investors with the most information about any given company: concentrated superinvestors, institutions as a whole, corporate insiders, members of Congress, and 5% holders. For IREN, those lenses return an unusual pattern — breadth without conviction.

Lens 1: the superinvestors — zero

We track 83 large, mostly long-only managers whose 13F portfolios we collect directly from SEC EDGAR — the concentrated, long-horizon cohort this site is built around. As of June 30, 2026, the number holding IREN was zero. It was also zero at March 31, 2026. This is not a small-sample quirk: across the same managers' portfolios, a $16 billion company with a contracted-revenue story is exactly the kind of name that shows up somewhere. It shows up nowhere.

Absence is not a verdict, and we do not present it as one. This cohort leans toward profitable compounders, and IREN is not one yet: for the fiscal year ended June 30, 2026, it reported revenue of $707.0 million and a net loss of $702.6 million — most of it $638.8 million of non-cash impairments on retired bitcoin-mining equipment — while AI cloud revenue grew from $16.4 million to $128.8 million. A manager can admire the contracts and still wait for the income statement. What the zero establishes is narrower and still useful: the re-rating so far has happened without a single one of the 83.

Congress: full Senate and House PTR record. 13D/G: filings through Sep 30, 2026. Short interest: FINRA biweekly settlement data through Sep 15, 2026.

Lens 2: institutions — breadth, arriving fast

Zoom out to the whole 13F market and the picture flips. At June 30, 2026, 696 institutions reported long positions in IREN, up from 499 at March 31 — a 39% jump in one quarter. Reported positions totalled 211,372,822 shares, and the dataset's reported aggregate value rose from $9.98 billion to $17.70 billion (+77%). By filer count, IREN went from a niche holding to a standard one in a single quarter.

Institutional breadth, 2026Q1 to 2026Q2
Chart 2: Institutions reporting a long IREN position and the reported aggregate value of those positions, 2026Q1 (n = 499 filers) vs. 2026Q2 (n = 696 filers), period ends Mar 31 and Jun 30, 2026. One caution, detailed in the methodology: for this foreign-domiciled CUSIP (Q4982L109) the dataset's reported value implies a per-share figure well above the market price, so we treat filer counts and share counts as the reliable series and the dollar aggregate as reported-but-unverified. Source: SEC Form 13F Data Sets, full-market aggregation.

Breadth like this is real demand — but it is not the same animal as conviction buying. A filer count in the high hundreds for a stock of IREN's size is what index inclusion, ETF baskets and market-making inventory produce mechanically. The next lens shows which kind of holder sits at the top of the register.

Lens 3: the 5% register — desks, not activists

Thirteen SC 13D/G filings cover IREN, and all thirteen are 13G — the passive form. There is not one 13D, the filing an investor uses when it wants something from management. The largest reporter is the Goldman Sachs Group at 9.4% (33,642,054 shares, as of June 30, 2026), followed by Bank of America at 5.8% (21,027,180 shares). The most recent filing, on September 30, 2026, is Citadel Securities at 4.5%. The other large names are of the same type — Susquehanna and Jane Street are market-making firms — and their recent direction is down: Susquehanna reported 7.0% at September 30, 2025 and 4.2% at December 31, 2025; Jane Street went from 6.4% to 4.7% over the same dates. Banks and trading desks hold inventory for many reasons, client facilitation among them; a 13G from a desk is evidence of activity, not of a view.

Lens 4: insiders — grants in, nothing bought

The Form 4 record is the cleanest lens of the six, because insiders are the people who know. Across IREN's entire parsed Form 4 record — 18 filings, with coverage reaching back to 2021 — there is not one open-market purchase by any insider, at any price, including the $29.31 closing low of July 29, 2026. What the record contains instead is selling and granting. In September 2025 the two co-CEOs, Daniel and William Roberts, each reported the sale of 1,000,000 shares at $33.131 — the same jointly held position reported by both, so counted once it is roughly $33.1 million — alongside derivative sales over 500,000 underlying shares on each of September 3 and 4, 2025. Director Christopher Guzowski sold 11,958 shares at $36.32 on September 16, 2025. On July 1, 2026, each co-CEO received grants totalling 9,651,525 shares at $0, the CFO received 26,968, and four directors received between 6,657 and 8,369 each. Grants are compensation, not purchases; they cost the insider nothing and say nothing about what insiders would pay. In the 90 days through October 2, 2026, insiders filed nothing at all.

Lens 5: Congress — zero

Across the full Senate and House transaction record we maintain, members of Congress have reported no trades in IREN — no buys, no sells. For a stock at the centre of the AI-infrastructure debate, the political-money lens is simply dark.

Lens 6: short interest — the one crowded position

The last lens now has its number. As of September 15, 2026 — the most recent FINRA settlement date — 83,089,334 IREN shares were sold short: roughly 23% of the 357,378,674 shares IREN has most recently reported outstanding to the SEC.

The build was steep. Short interest stood at 20,586,418 shares on January 31, 2025 and has roughly quadrupled since, up 168% in the twelve months to September 15, 2026. It peaked on July 31, 2026 at 98,219,154 shares, and has since fallen at three consecutive settlements — 94,246,133, then 93,610,835, then 83,089,334 — down 11.2% in the latest period and 15.4% from the peak.

One calibration: days-to-cover is 2.32. IREN trades tens of millions of shares a day, so a short equal to nearly a quarter of the reported share count is still only about 2.3 days of average volume — the crowding is in the share count, not in the exit. Set against the long side, the balance of this audit is complete: breadth without a single conviction buyer in the filing record, and a large, deliberate position on the short side — one that has been shrinking since July.

What would change the picture

We do not issue a view on IREN. We publish the checklist that would change the description above, in the order the data will arrive:

Until one of those prints, the filing record describes a stock owned by almost everybody's index and almost nobody's conviction.

80% Overlap, No Copycat Signal: Congress vs. the Superinvestors
Four of five congressional stock buys land in a stock the superinvestors hold — 688 shared names. But ticker by ticker, how often Congress buys a stock has almost nothing to do with how many managers hold it (ρ = 0.099), and the shared names did not pay better.

The median Senate stock trade is disclosed in 32 days — but 77.3% of the trades filed past day 45 belong to just three senators, and the slowest disclosure in the record took 953 days.
