How can I invest in them?

---

Buy MSFT who plans to buy 20-30% of Open AI.

Or, just buy the AI suppliers for probably more upside:
CRWV
IREN
NBIS

Robinhood announced this year they're going to be introducing PE options. Of course, you won't actually own any OpenAI but you'll be invested in something that does.

Nvidia

There are a number of mutual funds that seem to offer exposure to private shares purchased in the secondary market.

The question is - why would you want to?

I'm not sure I understand your question. I want to because I think the value of those stocks will go up. Why wouldn't I want to?

Neither OpenAI nor xAI is publicly traded as of February 2026. This means you cannot buy their shares on a regular stock exchange like the NYSE or NASDAQ through a standard brokerage account (e.g., no ticker symbols for direct purchase).Investing in OpenAIOpenAI remains a private company, with recent valuations in the hundreds of billions (reports mention figures around $500B–$830B in late 2025/early 2026 fundraising and secondary sales). It has no confirmed IPO date yet, though discussions point to a possible Q4 2026 or later public offering, potentially at a $1T+ valuation, contingent on factors like achieving AGI milestones or restructuring.Direct investment options (for accredited investors only):Accredited investors (generally those with $200K+ annual income, $300K+ joint, or $1M+ net worth excluding primary residence) can access shares via secondary/pre-IPO marketplaces. These include platforms like:Forge Global
Hiive
EquityZen
Others like Nasdaq Private Market or specialized brokers (e.g., TSG Invest affiliates).

These involve buying from existing shareholders (e.g., employees or early investors) often through special-purpose vehicles (SPVs) due to OpenAI's share transfer rules. Availability fluctuates, and minimums can be high.

Indirect exposure (available to all investors):Invest in Microsoft (MSFT) — OpenAI's largest partner and shareholder, with a major stake, profit-sharing agreement, and deep integration (e.g., Azure powers much of OpenAI's compute).
Other public companies benefiting from AI growth or OpenAI ties: Nvidia (NVDA), Amazon (AMZN), or Google (Alphabet/GOOGL), as hyperscalers provide infrastructure.
AI-focused funds or ETFs: Examples include ARK Venture Fund (offers some private exposure including OpenAI), Fundrise Innovation Fund (accessible to non-accredited investors with low minimums), or others like Destiny Tech100 (DXYZ) that hold pre-IPO stakes.
These provide partial or proxy exposure but not direct ownership.

OpenAI is actively raising massive private rounds (e.g., talks of $100B+ at high valuations), often led by SoftBank, Thrive Capital, and others, but these are typically closed to retail investors.Investing in xAIxAI (the company behind Grok) was acquired by SpaceX in early February 2026 (around February 2–3). It is no longer an independent entity, so direct xAI shares are no longer tradable separately on pre-IPO markets.Current status:xAI is now part of SpaceX, which remains a private company (no public trading).
SpaceX has been gearing up for a potential IPO later in 2026 (some reports suggest mid-year, like July, at enormous valuations potentially $1T+ for the combined entity).
If/when SpaceX goes public, that would effectively bring xAI (along with elements of X/Twitter from prior mergers) into the public markets indirectly.

Direct investment options (limited/accredited only):Pre-acquisition, platforms like Hiive, EquityZen, Forge, or Nasdaq Private Market offered xAI shares to accredited investors — but post-acquisition, these are no longer available for standalone xAI.
Exposure now ties to SpaceX private shares (if available via secondary markets for accredited investors) or waiting for a potential SpaceX IPO.

Indirect exposure (available to all investors):Invest in public AI-related companies that compete or align with xAI's goals (e.g., Tesla (TSLA) for Elon Musk ecosystem ties, or broader AI plays like Nvidia).
Some publicly traded funds or ETFs hold pre-IPO/private AI stakes (e.g., ARK Venture Fund or similar vehicles that may include SpaceX/xAI exposure indirectly).
No straightforward public proxy exists specifically for xAI yet, beyond waiting for SpaceX developments.

Key notes for both:Private investments carry high risk (illiquidity, valuation volatility, no guaranteed returns) and are restricted for non-accredited investors.
Always verify your accreditation status and consult a financial advisor or platform directly, as opportunities change rapidly.
For broader AI exposure without direct access, public stocks like Microsoft, Nvidia, or AI-themed ETFs remain the most accessible route.

The AI sector is moving fast, with massive fundraising and IPO speculation — monitor official announcements from the companies for updates.
