Now, Block Inc will replace US energy company Hess Corp in the S&P 500, upon its acquisition by Chevron. 

It will also become the second crypto-orientated company to join the benchmark index in recent weeks, and comes roughly two months after leading US crypto exchange Coinbase entered the S&P 500.
