Prediction Markets Shift Ahead of Key Events: Trump Surges, Ceasefire Speculation Grows

Prediction markets have been buzzing this week with sharp swings across several major platforms. At Polymarket, the top contract by volume remains the U.S. Presidential race, with over 13 million dollars traded on whether Joe Biden or Donald Trump will win in November. As of this morning, Trump has pulled ahead, trading at 57 cents to Biden's 38. That’s a five-point jump for Trump in just under 48 hours, driven by increasing attention on economic indicators and persistent concerns around Biden's age and debate readiness. The surprise came not from the shift itself, but the speed. As recently as Monday, Trump was at 52 cents, with Biden trailing only slightly closer. The sharp uptick suggests a broader reassessment of Biden’s viability heading into the first debate scheduled for late June.

Over at PredictIt, a similar trend is emerging, though the moves are slightly more conservative. Trump’s contract for the GOP nomination is now trading at 84 cents, a full 10 points ahead of where it stood last week. Interestingly, despite legal uncertainty, Ron DeSantis saw a small resurgence, jumping from 4 to 7 cents overnight. That bump coincided with a high-profile media appearance and renewed speculation about a possible brokered convention, even if such a scenario remains unlikely.

Metaculus, which aggregates forecasts from a more analytically driven crowd, still has Biden slightly favored in terms of electoral vote modeling. Their community gives Biden a 51 percent chance of winning the electoral college, down from 55 percent three days ago. That shift, while more moderated, still reflects realignment in forecasting sentiment following new polling out of Michigan and Pennsylvania.

One of the most surprising movements comes from a niche but rapidly growing area: markets around a potential ceasefire between Israel and Hamas. On Polymarket, the “Will a ceasefire be announced by June 30” market surged from 22 to 44 cents on Tuesday alone, after Axios reported breakthrough talks involving Qatari intermediaries. That doubling in implied probability was eye-catching, especially given how stagnant the market had been previously. But as of today, it's trickled back down to 36 cents, suggesting traders are still skeptical about a long-term agreement.

Another shift worth watching has played out on the Metaculus front, where forecasts for an AGI—artificial general intelligence—deployment by 2030 have inched back up to 19 percent from last week's 15. While that number might still seem low, it reflects a growing interest following recent statements from executives at OpenAI and Anthropic hinting at more aggressive development timelines.

An emerging pattern to keep your eye on is increased volume on non-political markets. The recent boom in sports betting integrations and entertainment markets—like “Will Dune: Part Two win Best Picture”—is beginning to draw the kind of liquidity typically reserved for electoral events. While still early days, platforms are actively expanding to tap into this broader spectrum of collective forecasting.
