War bets and coincidences

Paulo Coutinho

There is something deeply unsettling about markets that move before the world does. Not the usual anticipatory twitch of traders reading signals, but the kind of movement that looks less like foresight and more like foreknowledge. When bombs fall hours after bets are placed, the line between speculation and exploitation blurs – fast.

As gaming law expert I. Nelson Rose has argued, “insider trading is illegal – in securities trading and regulated sports betting.” Yet the architecture of certain prediction markets creates an uncomfortable paradox: systems designed to aggregate information may also reward those who already possess it.

Rose himself highlighted what appears to be troubling activity on platforms such as Polymarket and Kalshi. There were, in his words, “suspicious increases” in bets tied to U.S. airstrikes on Iran – placed mere hours before the attacks occurred. At least six accounts reportedly opened in late February and concentrated almost exclusively on contracts predicting the precise date the strikes would begin.

According to Bloomberg, Polymarket recorded $529 million in trades linked to the timing of the airstrikes. Much of the money clustered around February 28, with contracts priced as low as ten cents paying out a dollar if correct.

The platform also saw unusual betting on whether Iran’s Supreme Leader, Ali Khamenei, would no longer be in power by the end of March. Before February 28 had even concluded, it was announced that Khamenei had been killed. Again, markets appeared to move not with events, but ahead of them.

“It is ethically repulsive,” Rose wrote bluntly on his blog Gambling and the Law. And he is right. Turning war into a financial instrument is already morally fraught. Doing so with what appears to be insider knowledge crosses from discomfort into something far more corrosive.

The regulatory picture does little to reassure. As The Capitol Forum has reported, companies like Sporttrade have struggled to fit exchange-style models into existing U.S. gambling laws. Sporttrade’s concept – allowing users to buy and sell event-based contracts like financial assets – ran headfirst into a patchwork of state regulations. Years of lobbying and compliance yielded approval in only a handful of jurisdictions and, even then, in a diluted form, the Capitol Forum asserts.

At the same time, federally overseen prediction markets have pursued a different path, seeking legitimacy through commodities regulation rather than gambling law. The result is a structural mismatch: similar products, different rulebooks, and gaps wide enough for questionable behavior to slip through.

Markets are supposed to price risk, not privileged access. But when outcomes tied to war, geopolitics, and leadership are traded with uncanny precision, the suspicion becomes unavoidable – someone, somewhere, may be trading on more than probability.

Sound familiar? Macau has long lived with its own version of information asymmetry. Not at the gaming tables themselves, but in the financial markets orbiting the casino industry – in Hong Kong and New York, where shares of the Big Six rise and fall.

Across decades, fortunes have been built on well-timed positions linked to gaming cycles, regulatory shifts, and policy signals that were not always evenly distributed.

The mechanics differ, but the principle is the same: there are no coincidences.
