SpaceX Going Public: What Risks for Tesla and Opportunities for the French Investor?

SpaceX, Elon Musk's space company, is preparing to go public, opening a new investment avenue for individuals who want to bet on the entrepreneur's futuristic vision. Until now, Tesla was the only accessible gateway for investors to benefit from Musk's momentum. This development, revealed by Bloomberg Markets, could however weaken Tesla's position in the markets.

SpaceX: a public offering that disrupts access to the Musk universe

For several years, Tesla Inc. has remained the main vehicle to invest indirectly in Elon Musk's projects, thanks to the explosive growth of the electric car manufacturer. But the upcoming arrival of SpaceX on the stock market will create a new listed stock, offering investors direct access to a cutting-edge technology company specialized in aerospace and satellite launches.

This novelty fundamentally changes the landscape of Musk-related investments. According to Bloomberg, this IPO (initial public offering) will offer an unprecedented financial product, but potentially competing with Tesla to capture the attention and capital of retail and institutional investors.

Indeed, SpaceX could attract part of the capital traditionally directed towards Tesla, thus limiting the potential upside of the automotive stock. This phenomenon raises the question of diversification of investments within the Musk universe and portfolio management in light of this new offering.

Why this IPO represents a major challenge for Tesla and the markets

The public offering of such an innovative private company as SpaceX is a rare event that generates strong anticipation. According to Bloomberg, investors see in SpaceX a unique opportunity to participate in the space revolution, a rapidly expanding sector with strategic applications in telecommunications and defense.

However, this Musk duality – with two high-potential listed stocks – can also fragment the audience and financial flows. Tesla, valued at several hundred billion dollars, could see its stock less supported by investors who may prefer to spread their capital between the two companies, or even favor SpaceX for its novelty and exponential growth prospects.

This situation is all the more sensitive as Tesla is already facing strong competition in the automotive sector and must continue to innovate to maintain its lead. The SpaceX IPO thus adds to a market context where the valuation of technology companies is scrutinized closely.

Practical consequences for the French investor: how to adapt?

For French investors, this new Musk offering raises concrete questions, notably regarding taxation and investment vehicles. Tesla is accessible via the PEA, which allows benefiting from favorable taxation in France, whereas SpaceX, by entering the American stock market, will very likely be outside the PEA, thus accessible only through a standard securities account (CTO).

Here are some recommendations to integrate this development into an investment strategy:

  • Balance PEA and CTO: continue to hold Tesla in the PEA to benefit from optimized taxation while considering an investment in SpaceX via the CTO to diversify the portfolio.
  • Favor thematic ETFs: to limit specific risk, investors can look at technological or innovative ETFs, such as the MSCI World CW8 ETF, which could include both Tesla and, eventually, SpaceX or its competitors.
  • Monitor valuation: SpaceX being a previously unlisted company, its IPO must be analyzed carefully, especially the issue price and post-IPO dynamics, before taking a position.

Finally, it is recommended to use recognized platforms such as Trade Republic or Degiro to easily access the American markets and benefit from competitive fees.

Medium-term prospects for Tesla and SpaceX

The launch of SpaceX on the stock market does not mean the end of Tesla as Elon Musk's flagship stock, but marks a new stage in the diversification of his entrepreneurial empire. Tesla will have to continue innovating to retain investors and justify its valuation, while SpaceX will have to demonstrate its ability to generate stable and growing revenues in a competitive aerospace market.

For the markets, this IPO is a sign of maturity in the private space sector and could accelerate investments in space technologies. For French investors, it opens new opportunities but also new challenges in terms of portfolio management and tax optimization.

Impact for the French investor

The SpaceX IPO is excellent news for diversifying a portfolio focused on American technology stocks, but it requires strategic adaptation. French investors should:

  • Keep Tesla in their PEA to benefit from tax advantages, while using the CTO to access SpaceX, which will not be eligible for the PEA.
  • Carefully evaluate SpaceX's price and prospects before taking a position, considering the potential volatility of a tech IPO.
  • Consider integrating diversified ETFs such as the MSCI World CW8 ETF to reduce the specific risk related to a single Musk company.

Finally, staying informed about French regulatory and tax developments related to international investments is key to optimizing profitability and risk management.
