The Control Is His Own Paperwork
This dispatch continues The Mountain Pass Trades. That piece documented the pattern around MP Materials — the rare-earth miner holding the only operating REE mine in America and a 10-year Department of Defense offtake deal — through early June. What it could not yet say is what the filings themselves now show when you read the metadata instead of the dollar amounts.
Every SEC Form 4 filed since 2023 carries a structured yes/no field: was this transaction made under a Rule 10b5-1 trading plan? A marked checkbox is the filer telling the SEC these sales were pre-scheduled — locked in before the seller had whatever information the market later got. James Litinsky, MP's Chairman and CEO, uses that checkbox correctly. His January 7–8 sales ($19.25M) and his April 17–20 sales ($19.21M) both carry it, each with the same footnote: sales "effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person on September 16, 2025." Two tranches, three months apart, nearly identical size. That is what a plan looks like. View Dashboard →
Then May happens, and the paperwork changes.
What Changed in May
The May 12–13 tranche is 300,000 shares — the exact share count of the plan tranches, filed without the plan label. Then the structure breaks entirely: 400,000 shares over three days in late May, another 185,167 on June 3, and silence since.
Then Beijing Moved
Twenty-five days separate the last unmarked sale from Beijing's move. And inside the same window, MP's own Chief Operating Officer was doing the opposite — buying $1.5M of stock at $54–57 while his CEO sold $58.7M at $64–71. Two insiders at the same company, reading the same moment, trading against each other. View Dashboard →
Why the Checkbox Matters More Than the Dollars
This project just ran the opposite test on an NVIDIA director: a $445.6M liquidation that looked event-timed until his 2024–2025 filing history showed the same selling every year, unmarked checkbox and all — his standard practice, case downgraded within 24 hours of opening. Investigations →
Litinsky fails that same test in the other direction. His own 2026 filings prove he marks the checkbox and footnotes the plan when sales are plan sales. The absence in May is not his standard practice — it is a change in his standard practice, on his own paperwork, coinciding with a tripling of pace and preceding an adverse policy event by three weeks. The same instrument that cleared Stevens indicts the May filings here. That is what a control group is for.
What Has Not Been Shown
No document shows Litinsky knew Beijing's entity-listing decision was coming. China's move responds to MP's DoD deal, which has been public since 2025 — anyone could reason that retaliation was possible, and reasoning from public facts is not insider trading. It is also genuinely unclear that the listing is net-bad for MP: the company's value proposition is precisely that it is the non-Chinese supplier, and Beijing cutting it off arguably strengthens the DoD relationship that pays it. No post-June-28 MP price data is in this dataset yet.
An unmarked checkbox is the filer's representation, not independent proof the sales were discretionary. A second, newer trading plan could exist — though under the SEC's post-2023 rules those sales should still be checkbox-marked, so if a plan covered May, the filings are defective in a way that is itself reportable. A Form 4/A amendment asserting a plan for the May–June sales would materially change this dispatch and will be published here if it appears.
The COO's purchases cut against a company-wide-knowledge story: if MP's leadership knew something adverse was coming, Rosenthal bought into it twice. Either the two men read the same facts differently, or neither trade is informed. Both readings remain open. CFO Ryan Corbett ($4.26M sold Mar–May) and General Counsel Elliot Hoops ($1.89M sold Jan–May) also appear in the H1 record at much smaller scale.
Open Threads
Whether a Form 4/A appears asserting a plan for the May–June sales. What MP's first post-listing trading window shows — any insider activity after June 28 lands in the July scrape. Whether the Sept 16, 2025 plan was terminated (plan terminations are not required to be disclosed, but their footprint — the label vanishing — is exactly what these filings show). And the standing question from Part One: the same-day CRML Tanbreez trade of April 17 and the COO's timing relative to China's earlier REE export controls. Dashboard →
Behind the curtain, no wizard to find. Just a thunder organ, a wallet, and scaffolding left behind.
The noise is the point. The scaffolding is the story.
