Polymarket shelves nuclear detonation markets after outcryMarkets

What to know:

  • Polymarket has removed long-running markets that let users bet on the likelihood of a nuclear weapon detonating, amid the current conflict with Iran and criticism over war-related insider trading.
  • The nuclear-detonation contracts, which at times implied risks as high as 19 percent and drew millions of dollars in volume, have renewed concerns that insiders could profit from advance knowledge of military actions.
  • The controversy comes as the Commodity Futures Trading Commission weighs rules that would bar regulated exchanges from listing event contracts tied to war, terrorism, assassination and other activities deemed contrary to the public interest.

For a while, people have been betting on the possibility of a nuclear weapon being used on Polymarket. However, with the current tensions involving Iran and concerns about people using private information to profit from the conflict, the platform has now taken those betting options down.

Polymarket has launched a betting market focused on the possibility of a nuclear attack, raising worries that individuals with influence over military choices may be involved in placing these bets.

For years, prediction markets on Polymarket have asked people to estimate the likelihood of a nuclear weapon exploding by certain dates. These markets have consistently shown that users believe a detonation is unlikely, with results historically confirming ‘No’.

The contracts are being re-examined as prediction markets are facing scrutiny. A trader recently made over $400,000 by betting on the removal of Venezuelan leader Nicolás Maduro just before his capture by U.S. forces. This raises concerns that people with inside information could use these platforms to profit from events like wars – including the current conflict with Iran – and other military operations.

Historical trading suggests the contracts occasionally priced meaningful risk.

In 2023, predictions on the Polymarket platform briefly indicated about a 19% probability of a nuclear weapon being used before the year’s end.

A later market expiring in June 2025 traded near 12%.

Trading was brisk in the markets. The 2025 contract saw over $1.7 million in trading volume, and the 2023 contract had nearly $700,000 in wagers.

All this comes as U.S. regulators consider how to oversee prediction markets.

In 2024, the agency that oversees futures trading, the Commodity Futures Trading Commission, suggested new rules to prevent exchanges from offering bets on events like wars, terrorist attacks, or assassinations. These types of contracts would be prohibited because they are considered harmful to the public good.

According to Chairman Mike Selig, the Commission will soon release more detailed instructions regarding prediction markets.
