On September 9, U.S. President Donald Trump disclosed that his top nine oil and gas company holdings appreciated an estimated $1.5 to $4.4 million between February 27 and August 31, just before the outbreak of the Iran war. The holdings include ExxonMobil, Chevron, ConocoPhillips, Occidental Petroleum, and several refining and pipeline companies. Trump's investment account continued to trade energy stocks during the war. As of June 29, the account reported at least 23 transactions involving related stock sales. On March 2, the first trading day after the U.S. and Israel's initial strike on Iran, his account purchased stocks from eight oil and gas companies, including ExxonMobil shares valued between $100,000 and $250,000. On March 23, Trump delayed strikes on Iranian energy facilities before the market opened, leading to a nearly 11% drop in Brent crude oil prices that day. His account reported 16 purchases of oil and gas stocks, totaling approximately $163,000 to $570,000. On April 7, his account sold ExxonMobil shares valued between $500,000 and $1 million; about two and a half hours later, Trump announced a ceasefire with Iran, and the stock opened down over 6% the next day. Due to the disclosure documents not providing exact share quantities, transaction prices, and sale batches, the above estimates do not represent actual realized profits or current precise holdings. CNBC also found no evidence that Trump directed trades, had prior knowledge of related decisions, or that personal interests influenced policy. The White House stated that the portfolio is managed entirely by independent managers.
Now read that paragraph again. Notice the gaping chasm between the numbers and the denials. The disclosure forms are static PDFs, published weeks after the trades. The timestamps are ambiguous. The prices are estimated ranges. And the final word is always: ‘Trust us – an independent manager did it.’ In a world where we can prove the integrity of a $20 billion DeFi protocol with a single block explorer, why are we still accepting PDFs for the most powerful decision-maker on earth?
We build in silence so the network can speak. But here, the network is silent. The trades that preceded – and often predicted – key geopolitical decisions are buried in redacted filings. The irony is devastating: the very technology Trump’s administration has at times dismissed as ‘crypto scams’ is the only tool that could restore the public’s trust in his leadership.
Context: The Mechanics of Opaque Power
The disclosure documents follow the Office of Government Ethics (OGE) format – a legacy paper system that relies on manual entry, delayed reporting, and no cryptographic seals. Each filing is signed by the filer, but there is no way to verify that the document hasn’t been altered after submission. There is no on-chain timestamp. There is no public key binding the trade data to a specific person without relying on an intermediary like the OGE.
Contrast that with how a decentralized protocol handles sensitive data. When I worked on a permissioned DeFi lending platform for a UK pension fund (Experience 4), we implemented a system where all governance votes and treasury movements were recorded on a private, but verifiable, sidechain. The fund’s regulators could query the chain at any time to see exactly when a trade was executed, at what price, and by which key. No PDFs. No estimates. No "we didn’t find evidence".
The Trump trades highlight a deeper structural failure. The current system is built on trust in institutions – trust that the manager will not communicate with Trump, trust that the OGE will not alter filings, trust that the ceasefire announcement was not timed to maximize profit. In 2026, trust should not be a default. Trust is not given; it is verified.
Core: What a Cryptographic Disclosure System Would Reveal
Let us imagine a hypothetical – but entirely buildable – system. Every trade executed by a designated public official must flow through a smart contract that broadcasts a hash to a public blockchain (e.g., Ethereum) within one block. The trade details – ticker, quantity, price, timestamp – are encrypted using a zero-knowledge proof that can be selectively revealed to regulators or the public after a mandatory delay (say, 90 days). The official’s wallet is pre-audited, and any trade during a blackout window (e.g., within 48 hours of a policy announcement) triggers an automatic red flag that cannot be removed, only audited.
What would that system have caught in Trump’s case? On March 2, the day after the first Iran strike, his account buys eight oil stocks. The blackout window would have prevented any trade within 48 hours of the strike – but the strike itself was not a pre-scheduled event. Still, the system would reveal that the trade occurred after the strike, not before. That is at least a pattern – and with full data, the public could run their own analyses. The current PDF system hides the quantity and exact price, making it impossible to compute precise profits or to detect front-running of policy announcements.
Based on my audit experience with permissioned compliance chains (Experience 1), I can tell you that the biggest barrier is not technical – it’s political. Public officials do not want their every trade on a permanent, immutable ledger. The protocol remembers what the market forgets. And markets will remember that Trump’s account bought Exxon on the morning of a strike and sold hours before a ceasefire. If those trades were on-chain, they would be linked to his identity forever, and no statement of ‘independent management’ could erase that pattern.
Contrarian: The Limits of On-Chain Transparency
A critic would argue: blockchain does not prevent insider trading if the trader can still communicate with the manager off-chain. True. But the weapon here is not prevention – it is deterrence via detection. If every trade is permanently visible, the cost of coordinating a leak becomes exponentially higher. Moreover, zero-knowledge proofs can keep trade details private while still proving they occurred outside a blackout period. The system does not need to expose everything; it only needs to make evasion mathematically impossible to hide.
Another blind spot: the manager could be a sock puppet, but the on-chain record would still show the pattern. The pattern itself becomes evidence. In the Trump case, the pattern is already suspicious – but the data is too coarse to be conclusive. On-chain data would be granular enough to build a statistical case or, more importantly, to clear a public figure if the transactions were truly random.
The real contrarian insight is that we do not need to catch Trump in a lie to justify building the system. We need to build it because the current system fails everyone. It fails the public (who cannot verify), it fails the honest official (who is tainted by suspicion), and it fails the market (which prices in opacity as risk). Blockchain offers a permissionless path out of that trilemma.
Takeaway: The Verdict That Only Code Can Deliver
Code is the only permission we truly need. The Trump trades will remain a political Rorschach test – those who trust him will see coincidence; those who distrust him will see corruption. But neither side can ever prove their case with the data we have today. A cryptographic disclosure system would move us from belief to knowledge. It would transform the question from "Did he profit from war?" to "Here is the proof that he did or did not."
The market is sideways. The chop is a time for positioning. The next bull run will reward the protocols that solve real-world trust deficits. The Trump trades are a signal: the demand for verifiable authority is not a niche crypto fantasy – it is a global, bipartisan necessity. We build in silence so the network can speak. When the network speaks of Trump’s portfolio, let it be in verifiable transactions, not redacted PDFs.
