The French weather service has alerted police to suspected tampering with weather sensors, leading to a probe after a surge of bets on Polymarket related to unusual temperature spikes in Paris. Reports suggest that a trader may have used a hairdryer to artificially manipulate temperature readings, resulting in significant winnings, with payouts reportedly reaching up to $37,000. The bizarre claims have prompted official investigations into potential fraud, raising questions about the integrity of prediction markets. Prominent figures, including Vitalik Buterin, have called for the adoption of multi-source verification mechanisms to prevent such incidents in the future.
