’Abhorrent’: the inside story of the Polymarket gamblers betting millions on war

A new kind of market — and a new kind of moral test

A Guardian investigation reveals a sobering picture: thousands of people are treating armed conflict like a futures market. There is more than $500,000 staked on whether Russia will capture Kostyantynivka this year, $280m on a US‑Iran ceasefire, and $7.5m wagered on whether the US will invade Iran. Some gamblers complain the Institute for the Study of War’s front‑line maps are “a disjointed, incoherent mess” because the maps don’t settle their bets neatly. The result? Real human suffering becomes a scoreboard. Who finds that abhorrent? Many do.

How the platform grew — and how it defends itself

Polymarket bills itself as a prediction market that turns collective wagers into signals about the future. In mid‑2024 the site reported about $400m traded that year; it now sometimes trades roughly that amount in a single day. Longtime users say it increasingly feels like a casino where anything can be monetised — geopolitical shocks, celebrity gossip, existential bets. It has been reported that Polymarket posted a “Note on Middle East Markets,” arguing prediction markets can answer questions TV and social media cannot. It has also been reported that the platform allegedly hosted insider bets on US strikes, a charge that has intensified scrutiny.

Why critics and lawmakers are alarmed

Across Discord channels and X profiles, users openly discuss scenarios that could move markets — and, in some cases, it has been reported that they appear to be coordinating to influence how events are recorded. It has been reported that gamblers threatened an Israeli journalist to try to change a story so a bet would pay out. Critics call the behaviour immoral; US senators are pressing for regulation. Experts warn manipulation of high‑liquidity markets like this could ripple into broader financial systems, affecting institutions and even pension funds. That’s the rub: a crowd’s “wisdom” here could become a weapon.

The stakes are more than money

Polymarket insists it can supply “truth” where news cycles fail, but others see a moral and regulatory gap. As volumes and headline‑making wagers climb, the debate is no longer abstract: it’s about whether markets should be allowed to monetise the recording and even the course of violent events. Regulation? Transparency? A new code of conduct? The questions are urgent — and the consequences, as the investigation shows, could be grave.
