[Polymarket Withdraws NFL Player Participation Contracts, Certifies Bitcoin, Ethereum, and Solana Price Contracts on the Same Day] Odaily Planet Daily News: Prediction market platform Polymarket US withdrew two NFL player participation contract filings on August 26. The platform had completed certification with the U.S. Commodity Futures Trading Commission (CFTC) the previous day and planned to launch related products no earlier than August 27. On the same day, Polymarket US certified Bitcoin, Ethereum, and Solana price contracts. These three types of contracts were submitted in paired formats and categorized as swap contracts under the binary options subcategory. Both the NFL contracts and cryptocurrency contracts involve related classifications. A separate confidentiality request was submitted for the NFL compliance analysis documents, with Polymarket US requesting permanent non-disclosure on the grounds that public disclosure would reveal trade secrets and provide competitors with an unfair advantage. As of the time of record, another NFL American football starting eligibility contract remains in certified status. (Bitcoin.com News)
