TAE Technologies is a private fusion-energy company developing field-reversed-configuration reactors using hydrogen-boron fuel, along with power-management and life-sciences subsidiaries.
TAE raised more than $150 million in June 2025 and later signed an all-stock merger with Trump Media & Technology Group valued above $6 billion. The merger remains pending, so TAE is still private and the transaction value is not a completed funding round.
What Is TAE Technologies?
Founded in 1998, TAE has built a series of experimental fusion machines and is developing a commercial reactor concept intended to use hydrogen-boron fuel with lower neutron production than many alternatives.
Business Model and Key Products
TAE also operates power and life-science businesses. The central investment case remains the technical, regulatory, capital, and schedule path from experimental milestones to an economical power plant.
TAE Technologies Funding and Valuation History
TAE states that it has raised more than $1.3 billion in equity. A reconciled selected history groups approximately $140 million of earlier financing, $500 million in 2016, $280 million in 2021, $250 million in 2022, and more than $150 million in 2025.

Investment Case
The investment case depends on TAE Technologies converting its product position into durable growth while managing execution, competition, financing, and private-market constraints.
Long Research Record
TAE has advanced through multiple generations of fusion experiments.
Hydrogen-Boron Approach
The fuel cycle could offer operational and waste advantages if commercial performance is achieved.
Strategic Partners
Google and energy investors provide technical collaboration and capital.
Related Technology Businesses
Power and life-science subsidiaries may create intermediate commercial value.
Key Risks
Scientific Risk
Commercially useful net fusion power has not yet been demonstrated by TAE.
Capital and Schedule
Fusion development requires large, uncertain, long-duration financing.
Merger and Governance
The proposed transaction may be delayed, altered, rejected, or create governance and reputational complexity.
Commercialization Risk
Plant siting, regulation, supply chains, offtake, and economics remain unproven.
Valuation and Information Risk
The latest disclosed financing may be stale, and private-company financial information can be limited. The offered price may differ materially from both the last preferred round and current fundamentals.
Liquidity and Transaction Risk
Interests in TAE Technologies may be scarce, restricted, difficult to resell, and offered through an SPV whose fees and rights differ from direct preferred shares.
How to Buy TAE Technologies Pre-IPO Shares
- Confirm that TAE Technologies remains private. Check for an SEC registration statement, a confirmed listing, or a material corporate transaction before pursuing private shares.
- Confirm your eligibility. Many late-stage secondary offerings use Regulation D and are limited to accredited investors. Individuals may qualify through net worth, income, or specified professional criteria.
- Find a live opportunity. Search registered private-market platforms or work with a qualified broker. A platform’s inclusion here does not mean it currently lists TAE Technologies.
- Review the security and vehicle. Determine whether the offer provides direct company shares or an interest in an SPV. Review share class, liquidation preferences, voting rights, information rights, and the investment manager.
- Evaluate price and fees. Compare the offered price and implied valuation with the latest financing while accounting for platform fees, carried interest, SPV expenses, and security rights.
- Review transfer and exit restrictions. Examine company consent requirements, rights of first refusal, holding periods, and what happens if an IPO or acquisition never occurs.
Accredited-investor criteria: Under current SEC criteria, an individual may qualify through net worth above $1 million excluding the primary residence; income above $200,000 individually or $300,000 with a spouse or partner in each of the prior two years with a reasonable expectation of the same; or certain professional criteria. Review the SEC criteria.

TAE Technologies Valuation and IPO Outlook
TMTG and TAE said in June 2026 that they were targeting a closing in the fourth quarter of 2026 or sooner. An August update still described the merger as pending.
Investors should review the eventual registration statement, exchange ratio, closing conditions, dilution, governance, cash commitments, and technical milestone disclosures.
Investing in TAE Technologies Pre-IPO Shares | Conclusion
TAE Technologies offers differentiated exposure to hydrogen-boron fusion energy and related power technologies.
The opportunity should be weighed against execution, competition, valuation, information, dilution, and liquidity risks. Investors should verify current operating data and underwrite the exact security rather than relying on an assumed IPO.
