Circle, the company behind the USDC stablecoin, completed its IPO in the U.S., raising $1.05 billion by selling 34 million shares at $31 each. On its first day on the stock market, shares rose nearly 169%, reaching a valuation of $18.4 billion. This IPO is one of the largest in the crypto sector since Coinbase in 2021.

Its success reflects the growing institutional interest in crypto and could pave the way for future IPOs from other fintech companies.
