Newsom Signs Order Banning Prediction Market Insider Trading

Gavin Newsom executive order signed on Friday takes direct aim at political insiders who've been quietly cashing in on prediction markets — using government secrets as their edge. The California governor expanded state ethics rules to bar gubernatorial appointees from trading on platforms like Polymarket when the bets involve events they can influence or have privileged access to. It's a narrower move than what's happening in Congress, but it's the most concrete action any state executive has taken on this issue so far.

What the Executive Order Actually Covers

The order targets a specific class of state officials — those directly appointed by the governor, referred to as 'gubernatorial appointees.' Under the new rules, these individuals are prohibited from using 'confidential or non-public information' obtained through their official duties to place bets on prediction market insider trading platforms tied to political or economic outcomes they're in a position to shape.

The scope goes further than most people probably expect. The ban isn't limited to the officials themselves — it covers their spouses, family members, and former business partners as well. In other words, you can't sidestep the rule by having your wife place the bet. That's a meaningful detail that gets buried in most coverage of this story, and it suggests Newsom's team thought carefully about the obvious workarounds.

Newsom's announcement cited real examples of why this matters. His office listed six suspected political insiders who allegedly profited from US strikes on Iran by trading on prediction markets before the strikes became public knowledge. That's not a hypothetical — those are alleged cases of government employees or their associates treating classified operational information like a stock tip.

Public service should not be a get-rich-quick scheme.

The $410,000 Polymarket Bet That Everyone Noticed

One of the more striking examples Newsom's office pointed to happened in January 2026. A trader on Polymarket — the crypto-based prediction platform — placed a bet that the US would arrest former Venezuelan leader Nicolás Maduro. The bet paid out $410,000. The part that raised red flags: the trade was placed just hours before Maduro's capture became public information.

Nobody's been charged in that case — at least not publicly. But the timing is the kind of coincidence that's hard to explain away. Prediction markets are designed to aggregate public expectations. When someone with access to non-public government intelligence uses that edge on a public platform, they're not just bending rules — they're potentially compromising sensitive operations by creating a paper trail of informed bets that adversaries can monitor.

That national security angle is what's been driving congressional attention to this issue, and it's more alarming than the financial fraud dimension alone. If foreign intelligence services can watch American prediction markets and infer when a US government action is imminent based on unusual betting patterns, that's a genuine problem — one that goes well beyond whether an appointee pocketed some extra cash.

What Is the BETS OFF Act?

What does the BETS OFF Act prohibit?

The BETS OFF Act — short for Banning Event Trading on Sensitive Operations and Federal Functions — is the federal-level response to the same problem Newsom is addressing at the state level. Texas Congressman Greg Casar and Connecticut Senator Chris Murphy introduced the BETS OFF Act in March 2026, targeting prediction market bets tied specifically to war or death — the most sensitive categories of government action.

A separate bill, the PREDICT Act — Preventing Real-time Exploitation and Deceptive Insider Congressional Trading — was introduced in the same month by Representative Adrian Smith and Representative Nikki Budzinski. That one casts a wider net, prohibiting the US President, members of Congress, and other high-ranking officials from betting on prediction markets at all, regardless of the event category.

Two bills, same month, different chambers — that's not a coincidence. There's clearly enough political momentum to push something through, though whether either bill survives the legislative gauntlet is a different question entirely. The STOCK Act took years to pass and still has significant enforcement gaps. Prediction market regulation faces the same institutional inertia.

• BETS OFF Act: Bans government insiders from betting on markets tied to war or death
• PREDICT Act: Bans the President, lawmakers, and senior officials from all prediction market betting
• Newsom's executive order: Bars California gubernatorial appointees and their families from using non-public info to trade

Why Does Prediction Market Regulation Matter for Crypto?

Polymarket — built on the Polygon blockchain — is the most prominent platform caught in the middle of all this. It doesn't operate in the US officially; American users are geo-blocked following a $1.4 million CFTC settlement the platform reached in 2022. Yet the insider trading allegations being cited by Newsom's office and Congress are largely happening there anyway, through VPNs or non-US accounts.

That's the regulatory paradox prediction markets now face. The platforms moved offshore partly to escape US oversight. But the activity Newsom and Congress are targeting — American government officials using American classified information to trade — doesn't stop happening just because the platform is technically offshore. Jurisdiction follows the person making the bet, not just the server hosting it.

For the broader crypto space, this legislative push matters because it frames prediction markets as a governance and national security issue — not just a consumer protection one. That framing tends to generate faster, harsher regulatory responses. If the Gavin Newsom executive order becomes a template other states adopt, platform operators will face a patchwork of state-level restrictions on top of whatever federal rules emerge — a compliance nightmare that could reshape how these markets operate entirely.
