Space Stocks Are Ripping Higher After Spacex's Ipo Filing

• Space stocks have been in full focus this week after Elon Musk's SpaceX filed for an IPO.
• The news has driven sharp gains over the last two days for other space-tech companies.
• Planet Labs and Intuitive Machines have been among the biggest winners.

Wall Street has been buzzing since Elon Musk's SpaceX confidentially filed for an IPO on Wednesday.

That's lifted smaller space-tech names across the market over the last two days, with SpaceX's lofty valuation and public debut giving a boost to sentiment.

"On balance I would expect that a publicly traded SpaceX will result in greater appreciation for the business strength of SpaceX's assets, while also catalyzing increased awareness and appreciation of a broader growing space ecosystem," Daniel Hanson, a senior portfolio manager at Neuberger Berman, told Business Insider.

Here are some of the biggest two-day movers:

• Planet Labs: +24%
• Intuitive Machines: +24%
• York Space Systems: +18%
• Firefly Aerospace: +14%

• Viasat: +13%

The benchmark S&P 500 index is up just 0.6% over the same period.

But for all the momentum it has sparked for space stocks, the SpaceX IPO has also generated some controversy with other finance pros raising concerns.

As Apollo Global Capital chief economist Torsten Slok noted, the mega-IPOs expected from SpaceX, OpenAI and Anthropic, could lead to a significant concentration risk in the S&P 500. These high-profile companies going public could exacerbate what he sees as a growing problem.

Meanwhile, the Nasdaq's decision to implement a listing rule change to allow SpaceX to list quickly has been criticized by 'Big Short' investor Michael Burry and Wall Street veteran George Noble, who stated that the waiting period for companies is too important to bypass.
