Alain Rauscher Net Worth: Estimate, Sources, and How to Verify

As of May 2026, the most defensible estimate for Alain Rauscher's net worth sits in the range of €500 million to €650 million, driven almost entirely by his equity stake in Antin Infrastructure Partners, the Paris-listed infrastructure private equity firm he co-founded and still leads as Chairman and CEO. That figure is built from public share registry data, AMF filings, and Antin's published share price, not guesswork. Here's exactly how to get there and how to check it yourself.

Which Alain Rauscher are we talking about?

This is worth clarifying upfront because the name isn't unique. The Alain Rauscher most people are searching for in a financial context is the co-founder and CEO of Antin Infrastructure Partners, a mid-to-large infrastructure-focused private equity firm headquartered in Paris and listed on Euronext. His public profile is unambiguous: he studied philosophy at the École normale supérieure before pivoting to finance, built his investment banking career at BNP Paribas Corporate Finance, Lazard Frères, and Lehman Brothers across Paris, London, and New York, and then co-founded Antin. He holds a board position as Chairman alongside his CEO role, and his equity interest is held through a personal holding company called LB Capital.

If you're looking at a different Alain Rauscher, say an academic, a local entrepreneur, or someone in a completely unrelated field, this article won't be useful. The French company directory Pappers lists his directorial associations with multiple Antin-related entities, which is a quick cross-check if you want to confirm identity before reading further.

The net worth estimate: range and headline figure

The headline estimate of €500 million to €650 million as of May 2026 is anchored to his publicly disclosed shareholding. AMF filings from mid-2023 put his stake at approximately 53.86 million shares, representing about 30.86% of Antin's capital at that time, with more recent data from sources like SimplyWallSt suggesting the figure has grown to roughly 55.99 million shares. The January 2025 free share plan vesting added at least 850,960 shares directly to his name. Additionally, in January 2025 Antin disclosed a share placement of approximately 4.55 million shares at €10.40 per share, with 50% of that placement acquired by management including Rauscher personally.

Antin's share price has fluctuated significantly since the company listed in 2021. Using a working range of roughly €9 to €12 per share through 2025 and into 2026, and applying it to approximately 55 to 57 million shares, you arrive at a gross equity value somewhere between €495 million and €684 million. Trimming for taxes, holding company structure costs, and standard estimation uncertainty puts the realistic range at €500 million to €650 million. The €575 million midpoint is a reasonable single-number shorthand.

How this estimate is built: sources and methodology

Net worth estimates for private equity executives at listed firms are more tractable than estimates for, say, a privately held business owner, because the equity is publicly priced. The methodology here uses four layers of evidence.

1. AMF regulatory disclosures: France's financial markets regulator (AMF) requires major shareholders to disclose holdings above certain thresholds. Rauscher's 2023 disclosure put him at 53,861,333 shares and 106,003,917 voting rights (the higher voting figure reflects double-voting rights for long-held shares, a common French corporate mechanism). These are primary, verified figures.
2. Antin's Universal Registration Documents (URDs): Published annually and filed with the AMF, these include detailed tables of insider shareholdings, compensation arrangements, and the LB Capital holding vehicle structure. The 2023 URD lists approximately 54.7 million shares via LB Capital.
3. Euronext and company announcements: The January 2025 share placement and free share plan vesting disclosures added granularity on recent share acquisitions, confirming ongoing accumulation.
4. Antin's live share price on Euronext: Multiplying verified share counts by the current or period-average share price gives a gross equity valuation. This is a standard approach for any listed-company insider.

What this methodology cannot capture precisely: privately held investments outside Antin, real estate, personal savings, and liabilities. Those are estimated using industry norms for executives at his level and tenure, with appropriate uncertainty margins applied.

Where the money comes from: income streams

Salary and annual compensation

Antin publicly disclosed Rauscher's FY2024 variable compensation at €937,125 total, split into €655,987.50 (quantitative component) and €281,137.50 (qualitative component). This is the variable portion subject to shareholder vote under French commercial code provisions. His fixed base salary is not broken out in the same public disclosure, but for a CEO of a firm managing tens of billions in infrastructure assets, total annual cash compensation in the range of €1.5 million to €3 million per year is consistent with market norms for European private equity executives at this scale. Over a multi-decade career, that accumulates to meaningful cash wealth even before equity is considered.

Carried interest and fund economics

As a co-founder and senior partner of a private equity firm, carried interest is likely the most significant income channel beyond the listed equity stake. Carried interest is the profit-share that PE fund managers earn when fund returns exceed a hurdle rate, typically 20% of profits above an 8% preferred return. Antin manages multiple flagship funds; the recent close of Flagship Fund V is one example. The exact carry allocation to Rauscher is not publicly disclosed, but co-founders of infrastructure PE firms with assets under management in the range Antin operates typically accumulate tens of millions in carry over the life of multiple funds. This is a deferred income stream, often paid out over years, and it represents wealth that isn't fully captured in any single year's compensation disclosure.

Equity appreciation and dividends

Holding roughly 30% of a listed company means Rauscher participates directly in any dividends Antin pays to shareholders, and his net worth moves in direct proportion to the share price. This is the most volatile component of his wealth and the one most sensitive to market conditions, fundraising performance, and fee income trends at Antin.

Outside investments

For someone with his tenure in finance and capital markets, personal investments in other funds, real estate, or private companies are a reasonable assumption. There's no public record of significant holdings outside Antin, but it would be unusual for an executive of this profile to have no diversified investments. This component is treated as a moderate positive in the net worth estimate without a specific dollar amount attached.

Assets and liabilities worth factoring in

The single biggest caveat with any stake-based net worth figure is liquidity. Rauscher holds roughly 30% of Antin's capital. Selling that position in the open market would be practically impossible without moving the price significantly and triggering regulatory lockup or disclosure requirements. His real, spendable wealth is a fraction of the paper valuation at any given moment. That's standard for founders of listed firms, and it's why net worth estimates for this profile are always better read as a range tied to share price rather than a fixed number.

What could move this number up or down

Because the overwhelming driver of Rauscher's net worth is Antin's share price, anything that affects Antin's valuation or AUM trajectory is a direct signal. Watch for these specifically:

• Antin's share price on Euronext: a 20% move in either direction changes the net worth estimate by roughly €100 million at current share counts.
• New fund closes: the successful final close of Flagship Fund V was announced alongside record financial performance in early 2025; future fund raises and their size directly affect fee income and ultimately valuation.
• Insider buying or selling disclosures: the January 2025 OTC acquisition at €10.40 via LB Capital is exactly the kind of signal to track. AMF filings capture these in real time.
• Annual URD publications: Antin typically publishes its Universal Registration Document in the spring, with updated shareholding tables. These are the most reliable place to get current share counts.
• Changes in French wealth or capital gains tax policy: as a French resident with significant listed equity, any legislative change in wealth taxation or carried interest treatment would have a material effect.
• CEO succession or role changes: his compensation and the market's confidence in Antin are tied to his continued leadership. Any announcement of transition would likely move both.

For context, executives at comparable European listed asset managers, including some with profiles adjacent to the finance world covered on this site, can see net worth figures shift by 20 to 30 percent in a single year purely on equity moves. If you're primarily looking for a headline figure, you can also compare this with other rainer becker net worth style breakdowns that rely on listed holdings and market-priced equity. If you are also comparing other celebrity finance profiles like rammstein net worth, it helps to remember that equity-price swings can similarly drive large year-to-year changes. Rauscher's wealth profile is concentrated enough that this is a realistic range of variance.

How to verify this estimate yourself

You don't have to take the estimate on faith. Here's a practical checklist for checking or updating it using primary sources. Rheinmetall net worth is often discussed as a reflection of the company’s valuation, ownership structure, and recent financial performance.

1. Check Antin's current share price: Search 'Antin Infrastructure Partners' on Euronext Paris (ticker: ANTIN) for the live price. Multiply by the share count from the most recent URD.
2. Get the current share count: Download Antin's most recent Universal Registration Document from the Investor Relations section of antin-ip.com or from the AMF's BDIF database. Look for the 'Major Shareholders' or 'Shareholding Structure' section and find the LB Capital / Alain Rauscher row.
3. Cross-check AMF filings: The AMF's BDIF database (amf-france.org) hosts all insider transaction disclosures and major shareholder threshold crossing notices. Search for 'Alain Rauscher' or 'LB Capital' to find the most recent declarations.
4. Check company press releases on Euronext: Antin files regulatory news directly on Euronext. Compensation disclosures, share plan vestings, and placement announcements appear here and are dated and searchable.
5. Use Pappers or Verif.com for French corporate registry: These aggregate French company registry data (infogreffe). Searching 'LB Capital' and filtering for Rauscher as director confirms the holding vehicle is active and up to date.
6. FinancialReports.eu for ESEF filings: This aggregator hosts structured annual report data including insider transaction records tied to ESEF regulatory filings, useful for granular share movement data.
7. Apply a liquidity discount: Once you have the gross equity figure, mentally apply a 10 to 20 percent discount to reflect the practical illiquidity of a concentrated founder stake and the tax exposure on any future realization.

That's the full picture. If you are specifically wondering about Armin Ronacher net worth, it helps to separate his personal holdings from any unrelated figures with similar names. The estimate of €500 million to €650 million is well-grounded in public data, the methodology is reproducible, and the key inputs are updated regularly through Antin's mandatory regulatory disclosures. If you are specifically looking for a ray elbe net worth figure, use the same shareholding and share-price method described here for Rauscher. If the Antin share price moves materially between now and whenever you're reading this, adjust the gross equity figure accordingly and the rest of the estimate scales with it.
