Polymarket reforms Bitcoin settlement design as Binance trading spikes drop

Prediction market platform Polymarket has reformed its Bitcoin settlement mechanism, leading to an immediate drop in trading spikes on Binance, CryptoSlate reported on Oct. 27, 2026. A study by Guangzhe Wang indicated that earlier aggressive trading patterns on Binance subsided after the platform implemented a 60-second averaging process for opening and closing benchmarks. [1]

The operational adjustments followed an August reform intended to alter financial incentives associated with moving settlement prices, CryptoSlate reported. Polymarket sampled five-minute Bitcoin contracts on Oct. 27 using the new averaged benchmarks, replacing a single-snapshot rule examined in historical research. The original single-snapshot framework enabled 821 digital wallets to generate an estimated $8.2 million during earlier market cycles. [1]

Separately, TokenPost and Pluang reported that the probability of Bitcoin reaching $82,500 in October fell to 36% on Polymarket on Oct. 27. On the same day, Blockchain News reported that a cryptocurrency whale withdrew 11,330 Bitcoin from the Binance exchange platform. [2][3][5]

Polymarket operates as a decentralized, peer-to-peer prediction market utilizing blockchain technology, where share prices between $0.01 and $1.00 reflect event probabilities. Meanwhile, Bitcoin relies on a proof-of-work mechanism with a total capped supply of 21 million units. [9][10]

The platform continues to navigate regulatory scrutiny alongside its structural revisions. Bitcoin Magazine reported on Oct. 27 that the Commodity Futures Trading Commission reopened questions concerning Polymarket's commitment to exclude users located in the United States from trading. [4]
