Anthropic filed confidentially for its IPO in June 2026, targeting a valuation of approximately $965 billion — one of the largest technology listings in history. For the engineers, researchers, and operations staff who joined Anthropic early, this moment represents the culmination of years of work and deferred compensation. For many, it also raises an urgent question: how do you buy a home in San Francisco or Marin before, during, or after the IPO lockup — without selling the stock that is still appreciating?

This guide is written specifically for Anthropic employees navigating that decision.

What the Anthropic IPO Means for Your Equity

Anthropic raised a $30 billion Series G in February 2026 at a $380 billion valuation, followed by a $65 billion Series H-1 in May 2026 at a $965 billion valuation. The company also launched a $5–6 billion employee tender offer at a $350 billion pre-money valuation, giving early staff some liquidity ahead of the public listing.

At IPO, Anthropic will almost certainly impose a 180-day lockup period during which employees cannot sell shares. If you plan to buy a home near the IPO date — and with SF homes averaging just 18 days on market, the window is narrow — you need a financing approach that does not require selling locked-up shares.

Mortgage Strategies for Anthropic Employees

1. RSU Income Qualification

If you have been receiving and selling Anthropic RSUs through tender offers for at least two years, most jumbo lenders will average that income and count it toward your qualifying income alongside your W-2 salary. The key requirements are: two years of documented RSU income on your tax returns, a current equity grant letter showing at least three more years of vesting, and a lender experienced in equity compensation underwriting.

Example: An Anthropic senior researcher with a $350,000 base salary and a two-year average of $500,000 in RSU income might qualify for a purchase price of $5–6 million depending on debt-to-income ratios and down payment.

2. Pledged Asset Mortgage — Buy Without Selling

A pledged asset program allows you to use your investment portfolio — including vested Anthropic shares from prior tender offers, plus any publicly traded diversified holdings — as collateral for the down payment. You do not sell the shares. They remain in your account, continue to appreciate, and you avoid triggering a capital gains event.

Structure: Most programs require pledging 125–150% of the required down payment amount. On a $4 million home requiring $800,000 down, you would pledge roughly $1 million to $1.2 million in qualifying securities. California capital gains tax of up to 13.3% plus federal tax of 23.8% means this approach could save you $370,000 or more in taxes on a $1 million stock pledge vs. selling outright.

3. Asset Depletion Qualification

If your salary alone does not fully qualify you for the loan you need, an asset depletion program converts your liquid investment portfolio into a calculated monthly income. A lender will divide your total eligible assets — including stock from Anthropic tender offers, publicly traded holdings, and cash — by a set amortization period, typically 60 to 84 months. A $2 million liquid portfolio might generate $25,000 to $33,000 per month in qualifying income under this method.

Understanding the Bay Area Jumbo Market in 2026

The 2026 conforming loan limit in San Francisco and Marin County is $1,249,125. Alameda, Contra Costa, and Santa Clara counties are at $1,209,750. The neighborhoods closest to Anthropic’s offices — SoMa, Mission, Noe Valley, Castro, Potrero Hill — routinely see purchase prices between $2 million and $6 million. Marin County, favored by many Anthropic staff for its schools and lifestyle, averages $3–5 million for single-family homes.

Jumbo lenders are more sophisticated about equity compensation than conventional lenders. They understand RSU vesting schedules, deferred compensation, and pledged asset structures. The key is working with a mortgage broker who has relationships with these lenders and knows how to present your financial profile in the way that produces the best outcome.

Timing: Before, During, and After the Lockup

Before the IPO: Your RSU income from prior tender offers can qualify now. A pledged asset mortgage using publicly traded securities in your brokerage account is available immediately. Get pre-approved now so you are positioned to act.

During the lockup (first 180 days post-IPO): You cannot sell Anthropic shares, but you can still qualify using salary, prior RSU income history, and any public market holdings. A pledged asset mortgage is ideal here — you pledge what you have without triggering a sale event.

After lockup expiry: You have maximum flexibility, but prices may be higher and competition more intense. Starting early means you can close when the right home appears rather than when your lockup expires.

The SF Real Estate Window Is Open Now

In the first half of 2026, San Francisco home prices rose 22.2% year-over-year and 144 homes sold for $1 million or more over asking. The buyers driving those overbids are largely colleagues with the same equity structure you have. Waiting is not a neutral choice — it means competing against more buyers, paying higher prices, or both.
