According to Barron's, sports contracts accounted for 83% of Kalshi's trading volume in July. Kalshi is currently facing increasing legal challenges, with New Jersey having submitted the dispute to the U.S. Supreme Court, and Michigan authorities continuing to seek to block its operations.In terms of restricted jurisdictions, Canada brought about 450,000 visits to the Kalshi website in July, a significant increase from about 50,000 in August 2025; traffic from the UK also rose from 31,000 to 296,000.

first_img Robinhood Chain's daily gas fees surged 82 times in 11 days, surpassing all other chains

According to DeFiLlama data, the daily Gas fees of Robinhood's Ethereum Layer 2 network, Robinhood Chain, surged approximately 82 times within 11 days, surpassing all other blockchain networks to become the chain with the highest daily Gas fees. This network is built on the Arbitrum Orbit technology stack and has been live for only about two months.Data shows that the average daily Gas fees of Robinhood Chain climbed from about $56,000 on August 23 to approximately $3.75 million on September 1, continuously breaking historical records for several days. The fee surge is primarily driven by speculative trading of Meme coins, with the weekly trading volume on the on-chain DEX exceeding $1 billion at one point, where the token issuance platform Pons contributed the majority of the trading volume. As of September 1, the average transaction fee on this chain rose to $0.33, while Base was only about $0.0026 and Solana was about $0.013 during the same period.The high fees have also brought considerable revenue to Robinhood Chain. According to the protocol agreement, 10% of its net revenue must be allocated to the Arbitrum ecosystem, with 80% going to the Arbitrum DAO and 20% to the developer fund; in comparison, Arbitrum One's Gas fees on the same day were less than $15,000. The official Robinhood wallet still offers Gas subsidies for eligible transactions, which will continue until September 29.
