On Tuesday, South Korean AI services firm Elice Group saw its stock price plunge 28% on its debut trading day. A sharp cooling of investment sentiment in the sector has since derailed IPO plans for multiple companies. Elice raised 201.1 billion won (approximately $150 million) in its initial public offering (IPO). The company provides AI cloud services, AI-powered education and business software, and planned to allocate most of the IPO proceeds to launch portable modular data centers and related infrastructure. Against the backdrop of high inflation keeping borrowing costs elevated, investors are increasingly questioning whether massive capital invested in the AI sector can deliver short-term returns. Kim Hak-joon, an analyst at Seoul-based Kiwoom Securities, stated: "The market is concerned that such companies may fail to secure follow-on funding from investors." Elice’s latest stock price is 65,300 won, down from its IPO price of 90,500 won. According to relevant filing documents, the company received institutional subscription orders 388.84 times the number of shares available for subscription during its IPO.

Citi Research has released a report stating that it is no longer sufficient to view Aave solely as a crypto-native lending protocol. As tokenized assets, stablecoins, and institutional participation gradually integrate into mainstream finance, Aave is poised to be positioned as a decentralized collateral liquidity protocol. Projects including Aave V4, Horizon, and GHO all point to the intersection of collateral, liquidity, and financing. The report notes that if tokenization determines which assets enter on-chain ecosystems, and stablecoins become the default settlement base, Aave could help shape how these assets are financed, leveraged, used as collateral, and integrated into capital markets. Citi argues that as tokenization expands beyond stablecoins to money market funds, private credit, Treasuries, and even future equities, collateral circulation may eventually emerge as one of the most important use cases of tokenization. Aave provides a practical case study showing how tokenized assets can be used for collateralized borrowing, financing, and re-collateralization within the digital financial system, while also offering insights into the future of tokenized capital markets, securities financing, and even prime brokerage.
