Prediction markets rapidly re‑priced the odds of U.S. escalation in the Iran crisis, giving traders a near‑real‑time gauge of geopolitical risk. Markets on platforms such as Polymarket and Kalshi shifted as President Donald Trump combined new threats with signs of possible talks, and Bitcoin jumped more than 3.5% on Monday amid the moves.
Fabian Dori, chief investment officer at Sygnum Bank, says these crypto prediction venues have outgrown the “sideshow” label during geopolitical shocks. Increasingly, professional trading desks treat them as an input for macro risk assessment. Because prediction markets put real capital behind explicit, named outcomes—war, sanctions, ceasefires, regulatory rulings or protocol upgrades—they produce a clear, continuously updated probability signal that can complement price and flow metrics.
Dori noted that during the Iran tensions, markets pricing de‑escalation shifted ahead of mainstream reporting and showed a direct relationship with Bitcoin’s price action. That behaviour has encouraged some institutional teams to add event odds to their standard toolkits.
How institutions use prediction markets
Some desks now run prediction market feeds alongside traditional indicators such as funding rates, options surfaces and trade flows. ARK Invest’s adoption of Kalshi data into its process is an example of event odds being folded into institutional workflows.
In regulated operations, prediction markets are being treated less as buy/sell triggers and more as a contextual layer to frame scenario planning. The objective, Dori says, is to form a response before an event occurs; capital‑weighted, continuously updated probabilities help teams decide how to position for named outcomes.
Scale, scrutiny and integration
Activity in the space has surged to a level institutions can no longer dismiss as purely retail noise. In March, prediction market transactions reached roughly 191 million—an increase of about 2,838% year‑on‑year—with monthly notional volume near $23.9 billion.
Traditional exchange operators are taking notice: Intercontinental Exchange, owner of the New York Stock Exchange, completed a roughly $600 million investment in Polymarket on March 27, signaling confidence in the market model.
The challenge for professionals is to integrate these signals in ways that add analytical value rather than extra noise. At the same time, the growth of the sector has raised questions about fairness and market integrity. Reports that six Polymarket traders collectively netted about $1 million betting on the timing of U.S. strikes on Iran in late February sparked insider‑trading concerns. The platform also removed a market on a missing U.S. pilot after public backlash over related wagers.
