The White House Management Office issued an internal email on March 24, 2026 (before the Iran ceasefire event) warning executive branch staff that using privileged government information to place prediction market bets is a criminal offense. The email reminded staffers that placing wagers using privileged information "for the private benefit of an employee or any other third party" violates federal ethics regulations.

The warning was issued in response to suspicious trading around geopolitical events. Context cited in reports:
- Roughly 15 minutes before Trump's de-escalation announcement on Truth Social, $760M+ in oil futures changed hands (not just prediction markets)
- "Magamyman" account: $87K bet → $553K profit betting on Iran strikes 71 minutes before news became public
- Three Polymarket ceasefire accounts: ~$600K profit in hours before announcement
- Bubblemaps: 6 suspected insider accounts, $1.2M collectively on Iran strikes

The warning was first reported April 10, 2026, after the ceasefire trading incident became public.

The House Democrats letter to CFTC (April 7) specifically cited "recent high-profile instances of alleged insider trading on prediction market platforms relating to U.S. government actions — including the military's intervention in Venezuela and our recent attack on Iran." Response requested by April 15.

A bipartisan bill (PREDICT Act — Preventing Real-time Exploitation and Deceptive Insider Congressional Trading Act) was introduced March 25 to ban members of Congress, the President, and executive branch officials and their families from trading on political-event prediction markets.

## Agent Notes

**Why this matters:** The White House warning is the most important institutional signal this session. It means the executive branch simultaneously (a) suing states to protect prediction markets as CFTC-regulated financial instruments AND (b) issuing internal warnings that its own staff cannot trade on these same markets because of insider trading risk. The two positions are not contradictory but they reveal a tension: prediction markets are legitimate financial instruments when used by civilians aggregating dispersed knowledge, but they are insider trading vectors when used by government officials with nonpublic information.

**What surprised me:** The warning was issued March 24 — before the most dramatic ceasefire trading incident. The administration had already internally acknowledged the insider trading pattern. The March 24 warning + April ceasefire trading is a sequence that shows the warning was either ineffective or didn't reach the relevant actors.

**What I expected but didn't find:** Whether any White House official or staffer was actually investigated or disciplined following the March trading incidents. The warning is preventive, but there's no reporting on enforcement.

**KB connections:**
- `information-aggregation-through-incentives-rather-than-crowds` — institutional acknowledgment that the mechanism is being exploited for insider trading
- `congressional-insider-trading-legislation-for-prediction-markets-treats-them-as-financial-instruments-not-gambling-strengthening-dcm-regulatory-legitimacy` — PREDICT Act extends this thread; the legislative response is treating prediction markets as financial instruments (insider trading law applies), which strengthens the DCM legitimacy claim

**Extraction hints:** Primary claim: White House internal insider trading warning on prediction markets constitutes institutional acknowledgment that the information aggregation mechanism is being exploited by government insiders, creating a state-as-insider dynamic that prediction market information aggregation theory does not anticipate. The PREDICT Act is a secondary claim — bipartisan legislation applying insider trading law to prediction markets strengthens the "financial instrument, not gambling" framing.

**Context:** The White House issued this warning while simultaneously suing states to protect prediction markets as CFTC-regulated financial instruments. The two positions coexist: prediction markets are legitimate financial instruments AND government officials cannot use nonpublic information to trade on them.

## Curator Notes

PRIMARY CONNECTION: `information-aggregation-through-incentives-rather-than-crowds`
WHY ARCHIVED: White House institutional warning (March 24, before ceasefire) is the most direct acknowledgment that prediction markets are insider trading vectors when information is concentrated in government actors; issued by same administration defending these markets in federal court
EXTRACTION HINT: The claim is about the structural tension between prediction markets' "aggregation tool" function and their "insider trading vector" function — both are real, they apply to different epistemic populations; write this as scope qualifier on existing aggregation claim
