Wall Street's private wealth divisions are deploying a classic relationship-banking strategy: extending loans today against illiquid private stock to founders and early employees at leading AI and tech companies, betting that these borrowers will become extraordinarily wealthy clients once their firms go public.

The approach is delivering measurable results. Goldman Sachs reported that its private wealth management loan balances in San Francisco have climbed 50% since 2023. JPMorgan has recorded a tenfold increase in global demand for private bank lending in recent months. These credit facilities are not opportunistic consumer lending — they are strategic positions designed to capture underwriting mandates and wealth management relationships when borrower companies pursue public listings, anchoring what is shaping up to be the largest wave of US IPOs since 2021.

The Loan-to-IPO Pipeline

Founders and early employees at private companies frequently face a structural financial challenge: substantial net worth on paper, limited cash in practice. Their wealth is tied up in shares they cannot readily sell, while mortgages, tax obligations, and expiring stock options create ongoing liquidity needs.

Banks address this by extending credit against illiquid shares through instruments such as short-term unsecured loans and share-pledge facilities. The founder obtains liquidity without diluting equity. The bank secures a relationship that positions it favorably for underwriting roles and wealth management engagements when the company eventually lists.

Share-backed lending to pre-IPO founders is not new — major banks have offered such facilities for years. What has changed is the scale and concentration of exposure in AI companies, where private valuations have reached levels previously seen only among public megacaps. The pool of borrowers sitting on nine- and ten-figure paper stakes has grown substantially as companies like OpenAI, Anthropic, and SpaceX have raised unprecedented private rounds at escalating valuations.

Morgan Stanley illustrated the potential returns from this model, generating over $70 billion in net new assets from IPOs in Q2 2026 alone, driven primarily by SpaceX.

A Historic IPO Window

US IPO activity in 2026 has reached exceptional levels. Listings excluding SPACs and financial vehicles have raised approximately $230 billion year-to-date, a level not seen since the bull market conditions of 2021.

The surge follows a prolonged public-markets drought. Rising interest rates and valuation compression through 2022 and 2023 effectively shuttered the IPO window for most technology companies, creating a backlog of maturing private firms that had delayed listings. The 2026 wave represents a partial unwinding of that backlog, now amplified by AI-sector enthusiasm that has pushed private valuations to record highs.

SpaceX's anticipated $75 billion IPO, launched in June, has been the dominant story. Anthropic, now valued at $965 billion, may pursue an IPO as early as October 2026. OpenAI has already confidentially filed for its own public listing.

Law firm Addleshaw Goddard reported that its stock-backed lending deals doubled between December 2025 and July 2026, indicating that the infrastructure supporting these transactions is scaling rapidly across the financial system.

Implications for Crypto and DeFi

The mechanism of share-backed lending parallels a core function of decentralized finance: enabling holders of volatile or illiquid assets to borrow against them without triggering a sale. The distinction is that Wall Street is applying this model to private equity stakes rather than to ETH or BTC.

The influx of AI IPO capital carries direct implications for crypto markets. With roughly $230 billion flowing into new tech listings, that capital competes with digital assets for portfolio allocation.

The trend also establishes precedent for tokenized equity and on-chain lending. Traditional finance is effectively recreating, in a bespoke and costly form, what DeFi protocols such as Aave and Compound execute programmatically. If private stock could be tokenized and deployed as collateral in DeFi protocols, the efficiency gains would be substantial. Several startups are already developing solutions in this area, though the regulatory path for tokenized private securities remains unresolved in most major jurisdictions.

Risk Factors

The lending boom carries notable risk. Banks are extending credit against assets with no public market, no daily price discovery, and limited liquidity. If the IPO window closes — whether due to a macroeconomic shock, regulatory change, or market fatigue — those loans become significantly more difficult to value and potentially harder to recover.

In 2022, when technology valuations collapsed, share-backed loans to founders became problematic across multiple institutions. The current concentration of lending in AI companies adds a layer of sector-specific risk that warrants scrutiny, particularly because private AI valuations have in some cases exceeded those of established public technology companies with comparable or greater revenue.
