LONDON — The dispatches from tomorrow's trading floors carry a message of relative calm: no further nation, according to the oracles of Kalshi Exchange, is likely to follow Britain's turbulent example and quit the European Union before the close of this decade. At a mere eight per cent probability, the markets have rendered their verdict — the great continental experiment, battered though it may be, shall endure. The stakes are considerable. Since Britain's bruising departure, eurosceptic movements have stirred in France, Italy, and sundry corners of the bloc, each threatening to unravel decades of painstaking economic and political integration. Yet market consensus, drawing on some four thousand dollars in daily wagers, finds these movements wanting — loud in the street, perhaps, but unlikely to reach the ballot box with decisive force. Should a snap referendum be called in Rome or Paris, however, prediction markets would revise their figures with considerable haste.
