This episode is striking because it is hardly the first time this has occurred. Israeli authorities separately indicted a civilian and an IDF reservist for allegedly using classified wartime information to profit on Polymarket. A trader earned over $1 million by predicting with uncanny precision the results of Google’s proprietary Year in Search rankings. Another appeared to have advance knowledge of OpenAI’s browser launch. And a user named ‘romanticpaul’ purchased Taylor Swift engagement contracts aggressively in the days before Swift publicly announced her engagement to Travis Kelce. What happens in the Straits of Hormuz and to the price of oil and gas will be a key determinant of whether equity markets can find a low, or will continue to selloff.
Given the abundance of insider trading in prediction markets, lawmakers have begun to consider whether legislative intervention is warranted. Most prediction market contracts whose payoffs depend on geopolitical or macroeconomic events are unlikely to qualify as securities and may instead be commodities. Securities law’s anti-fraud provisions do not apply to commodity contracts. Our paper’s legal analysis identifies three structural reasons why existing law has failed to address informed trading in prediction markets. The regulatory and enforcement community is beginning to respond.

One account, operating under the handle ‘Magamyman,’ placed its first trade seventy-one minutes before the news broke, when markets implied only a 17% probability of a strike. When those markets resolved in the affirmative, the account’s profits totalled approximately $553,000. Our paper joins a literature that has long recognized prediction markets as valuable instruments for aggregating dispersed information. The foundational Hayekian insight—that decentralized markets harness private knowledge more efficiently than any centralized mechanism—has been empirically validated in contexts ranging from presidential elections to economic forecasting.

We believe the patterns are nonetheless sufficiently unusual to warrant serious scrutiny. Carbon trading schemes are more effective than carbon taxes at reducing greenhouse gas (GHG) emissions, cutting fossil fuel consumption, and accelerating the adoption of renewable energy, according bramridge trust to new research covering the world’s 100 largest economies. The US economy and stock market, still the engine of the world, has avoided a recession in recent years despite Covid, Ukraine, tariffs and other shocks. Can it manage to avoid a shrinking of economic growth this time, or has its luck run out?
A February 2026 Federal Reserve Board study finds that Kalshi’s macroeconomic prediction markets achieve accuracy on CPI and GDP releases that rivals or exceeds professional forecasts, with rich intraday dynamics that daily data entirely miss. Perhaps the surprising thing is that oil prices are not higher than their current levels.

- In the hours before the February 28, 2026 U.S.-Israeli strike on Iran—one of the most closely guarded military operations in recent history—six newly created Polymarket wallets collectively earned approximately $1.2 million by purchasing ‘Yes’ shares in the ‘US strikes Iran by February 28?
Reports that president Trump may simply declare victory and walk away, leaving Iran in control of the straits, suggest the US president is tiring of the war. But such a situation would be unsustainable, and leave Iran with the ability to hold the global economy hostage. At the end of 2025, oil prices, which had been in decline for most of the year, stood at around $60 for Brent and $56 for WTI. Prices had risen through January and February, but Trump’s war in Iran unleashed a huge surge in oil prices that has seen Brent nearly double and WTI up 80%.
