PreStocksFi has launched on the Solana blockchain, allowing investors to buy and sell tokenized shares of closely held companies such as SpaceX, OpenAI, Stripe, Discord and Kraken. The platform, branded as PreStocks, brings a pre-IPO market to crypto traders by issuing tokens that represent an economic interest in the underlying private-company equity. Liquidity on the new venue is currently thin, the project’s backers said, warning that limited order depth could lead to large price swings until trading activity scales up. The development adds to a growing effort across crypto networks to package real-world assets into on-chain instruments, offering 24-hour trading and fractional ownership. Separately, Robinhood added the Floki memecoin to its trading roster, extending the retail broker’s lineup of digital-asset offerings.
