The SEI ecosystem is experiencing significant growth with several key developments in December. CoinShares has launched its Staked SEI ETP on Interactive Brokers, marking the first time SEI products are available through a major global brokerage platform. This move allows institutional clients to invest in SEI's on-chain yield products directly through their brokerage accounts, representing a milestone in compliant financial infrastructure. Kalshi, a CFTC-registered prediction market, has integrated SEI and USDC for event execution, enabling real-time settlement of events such as politics and macroeconomics. This integration signifies the first deep collaboration between a regulated event market and a Layer 1 blockchain. Additionally, Vanguard has included SEI in its DIME ETF, positioning SEI as a long-term asset for qualified investors. SEI's inclusion in Coinbase's COIN50 index further solidifies its status as a mainstream digital asset. Meanwhile, exchanges like OKX and MEXC are expanding SEI's reach, and AI initiatives by Allora and Cambrian are enhancing SEI's DeFi capabilities, establishing it as a hub for AI-driven blockchain applications.
