Traders on Polymarket are capitalizing on weather predictions to earn substantial profits. A trader known as neobrother has accumulated over $20,000 by focusing on weather markets, particularly the daily high temperatures of major cities like Buenos Aires and New York. Utilizing a "temperature laddering" strategy, neobrother places low-cost bets across a range of temperatures, achieving high returns when the actual temperature falls within this range. Another trader, Hans323, employs a different approach, betting heavily on low-probability events with asymmetric risk-reward ratios. Hans323 made a notable profit of $1.11 million from a single $92,000 bet on London's weather, despite only an 8% chance of success. Both traders leverage data-driven strategies and real-time weather models to maximize their returns in these niche markets.
