4E: US regulators investigate insider trading, Citigroup raises stablecoin forecast, Solana ecosystem breakthrough

ChainCatcher news reports that, according to 4E observations, the SEC and FINRA have launched investigations into certain cryptocurrency strategic reserve companies, focusing on unusual trading volumes and stock prices days before announcements. Officials warn that related companies may violate the Fair Disclosure Rules, and lawyers say such letters often indicate the beginning of an in-depth investigation into insider trading. Since the beginning of this year, there has been a surge in treasury companies mimicking the Strategy (MSTR.O) model, heavily buying Bitcoin and other tokens through equity and debt financing.
Citibank has raised its forecast for global stablecoin issuance in 2030 to $1.9 trillion (baseline scenario), with a potential peak of $4 trillion in a bull market, corresponding to an annual trading volume of $200 trillion. However, the report emphasizes that bank token trading volumes may surpass this, expected to exceed $100 trillion by 2030, with stablecoins, bank tokens, and CBDCs coexisting in the long term.
On the ecological front, Solana's stablecoin supply surpassed $30 billion this week, and the ecosystem's TVL exceeded $40 billion. Industry insiders believe that the explosion of RWA and stablecoin business is driving Solana to become a new generation of mainstream funding platform.
In terms of corporate movements, SharpLink (SBET) announced a partnership with Superstate to issue tokenized SBET stock on Ethereum, becoming the first publicly traded company to attempt this. Future compliance trading may be realized in AMM and DeFi protocols.
4E reminds investors: regulatory tightening coexists with new business models, and market opportunities and risks are also expanding. Investors should pay attention to the progress of U.S. investigations and policy directions, while also being wary of valuation bubbles and compliance pressures arising from rapid industry expansion.
