BRUSSELS — Dispatch from a continent watching its flanks: prediction markets give a 16% probability that the European Union will shed a member state before the decade closes, according to Kalshi exchange. The odds favour cohesion, but one-in-six is no statistical footnote — it is the sound of boots pacing outside the exit door.

The stakes could scarcely be higher. Brexit cost Britain years of parliamentary bedlam and the EU a significant economy; a second departure would shake the bloc's foundational claim that membership, once granted, is a one-way gate. Market consensus at 84% still backs unity prevailing, yet the mere liquidity of this contract — $18,657 traded in a single day — confirms that investors are placing real money on the question, not merely philosophising over café tables.

A surge in Eurosceptic governments, an acute economic shock, or a constitutional crisis in a smaller member state could rapidly reprice those odds upward. Conversely, deeper fiscal integration or a common security threat has historically tightened the Union's ranks.
