Tech stocks rose to start the holiday-shortened week as investors looked to the latest mega IPOs and continued to assess what Nvidia’s latest earnings mean for the artificial intelligence trade.

Last week, Elon Musk’s rocket company SpaceX (SPAX.PVT) filed its S-1 IPO prospectus, revealing details of its financials. ChatGPT creator OpenAI (OPAI.PVT) is also reportedly planning to file for an initial public offering in the coming weeks, and its competitor Anthropic (ANTH.PVT) is expected to follow soon with an IPO as early as this fall.

The three mega IPOs are expected to take the artificial intelligence trade on Wall Street to new heights and test the limits of investors’ appetite for the tech theme, while the rivalry between OpenAI and Anthropic will play out in a new arena.

The AI trade got a boost last week after industry leader Nvidia (NVDA) reported quarterly results that beat Wall Street expectations and delivered a better-than-expected second quarter outlook.

While first quarter earnings season has mostly wound down, a handful of tech companies report results this week, including Zscaler (ZS), Marvell Technology (MRVL), Salesforce (CRM), and Dell Technologies (DELL).

Yahoo Finance’s Jared Blikre reports:

Mega initial public offerings from SpaceX (SPAX.PVT) and OpenAI (OPAI.PVT) could push the artificial intelligence trade deeper into bubble territory — just as rising yields make investors more demanding about growth that may take years to arrive.

Bank of America’s Michael Hartnett estimated that adding mega IPOs to today’s AI leaders could push market concentration from 40% currently toward 48% of US market cap, above the peaks of the Roaring ’20s, Nifty Fifty, Japan ’80s, and dot-com bubble — though still below the railroad boom of the 1880s.

That is where the bond market comes in. SpaceX and OpenAI would ask investors to pay for growth years into the future, while rising yields make that wait more expensive.

The inflation backdrop is already close to BofA’s danger zone.

Yahoo Finance’s Ines Ferre reports:

SpaceX is striking while the AI boom is hot, and its IPO is taking up all the space.

Wall Street digested the $2 trillion valuation that the Elon Musk-led rocket and satellite company seeks after filing its IPO prospectus last week.

The company's ambitions span from colonizing Mars to creating a network of orbital AI data centers. It sees a total addressable market of $28.5 trillion, mostly coming from AI.

"This is a company that is investing very heavily, very heavy capex spend into AI infrastructure and into their Starship vehicle, which is going to enable all of these future businesses," said Chad Anderson, Space Capital founder and CEO. The venture capital firm's largest holding is SpaceX (SPAX.PVT).

Nancy Tengler, CEO of Laffer Tengler Investments, which invests in Tesla (TSLA), said her firm is interested in SpaceX, as one of her funds also owns Planet Labs (PL) and Rocket Lab (RKLB).

"We see it as additive," she said. "I think ultimately SpaceX and Tesla merge."
