Tech stocks rose on Monday after the US and Iran agreed to a ceasefire, buoying overall markets on optimism that the four-month-long war that has weighed on the global economy could begin to wind down.

Following its blockbuster public debut on Friday, investors will be closely watching how SpaceX (SPCX) shares open and trade throughout this holiday-shortened week for further bullish signs. SpaceX's IPO was the largest in history, making the rocketry and satellite company more valuable than Tesla (TSLA) and making Elon Musk the world's first trillionaire.

It also sets the stage for two other high-profile IPOs that could come as early as this year, from the dominant AI startups OpenAI (OPAI.PVT) and Anthropic (ANTH.PVT). Both have confidentially filed paperwork to go public, setting up a showdown between the rivals.
