Kalshi traders flip from bearish to bullish on September Bitcoin price
Kalshi traders have repriced September Bitcoin contracts from bearish to bullish as the cryptocurrency recovered from a dip below $80,000. The platform now shows strong odds Bitcoin hits $85,000 this month and 53% odds it drops below $72,500, reflecting volatile sentiment on the regulated prediction market. Multiple crypto-linked event contracts are active, including year-end price levels. The rapid repricing follows a 40% surge from July lows and a brief correction that tested the $80,000 support level.
The speed of Kalshi's sentiment reversal exposes how thin its crypto books amplify price swings. Traders who bought the dip below $80,000 now face a compressed window before month-end resolution locks capital for weeks. The 85% $85,000 pricing leaves minimal edge for late entrants unless spot continues climbing.
This creates a direct arbitrage with Polymarket's year-end $80,000 contract, which holds more optimistic odds on the same price action. Sophisticated traders will exploit the venue divergence rather than bet on direction alone. For Kalshi, the volatility is a double bind: it attracts flow but trains users to expect rapid repricing that its liquidity cannot support without slippage.
