Nuclear startup X-energy began its IPO roadshow Wednesday with a target price of $16-$19 per share, potentially raising $814.3 million. Amazon backed a $500 million Series C-1 round and committed to purchasing five gigawatts of nuclear power by 2039. X-energy develops high-temperature, gas-cooled reactors using TRISO fuel. The company faces a patent dispute with Standard Nuclear. Small modular reactor startups aim to overcome traditional nuclear development delays and costs.
