Why Equity Holders Participate

The Matching Program: One of the Best Deals in Corporate Philanthropy

Anthropic's employee matching program is the primary reason equity enters DAFs — and for good reason. Under the historical terms, the economics are extraordinary for anyone with charitable intent of any kind:

Anthropic Careers

This means an early employee who wanted to donate $500K to their alma mater over their lifetime could instead direct $2M there through the matching program. An employee planning to support their local hospital could triple their impact. The financial benefit is cause-agnostic — you don't have to give to AI safety or EA-aligned charities to benefit from the match.

For employees with any charitable intent at all, not participating in the matching program means leaving substantial value on the table. The match is "free money" from Anthropic directed to charities of the employee's choice.

The Tax Case for Donating Stock (At Any Time)

Separate from the matching program, there's a straightforward tax case for donating appreciated stock rather than selling it and donating cash. This applies to any charity, any stock, and at any time — pre or post-IPO:

The combined California capital gains rate (20% federal + 3.8% NIIT + 13.3% state ≈ 37%) means that for every dollar of stock sold rather than donated directly, ≈37 cents go to taxes. For an employee with $10M in equity who plans to give $2M to charity over their lifetime, donating stock directly saves ≈$740K versus selling first.

This is standard wealth management advice for anyone holding appreciated stock with charitable plans.

What's Special About Pre-IPO?

The tax case for donating stock applies equally pre- and post-IPO. The pre-IPO-specific advantages are structural and behavioral:

1. The matching program window is NOW. The matching terms are set at the time of participation. Employees who joined under the 3:1 program got far better terms than those joining under 1:1. The program could theoretically be further reduced or eliminated. Participating sooner captures better terms.

2. Behavioral pre-commitment before liquidity. Behavioral economics research consistently shows that commitment is easier before resources feel "real." Pre-IPO, equity is paper wealth — committing a percentage feels costless. Post-IPO, the same equity shows up as a dollar amount in a brokerage account, and giving feels like a loss.

3. The 409A discount makes pre-IPO deductions smaller. Pre-IPO, the IRS values private company common stock using 409A valuations, which are typically 50-70% below the latest preferred stock price. This means the tax deduction for a pre-IPO stock donation is smaller than the deduction for the same shares donated post-IPO at full market price. In terms of deduction value alone, post-IPO donation is slightly better — the pre-IPO advantage is the behavioral commitment, not the tax treatment.

4. Valuation expectations don't change the calculus much. Whether you expect the stock to rise or fall post-IPO, the capital gains avoided by donating stock directly is the same. Higher future valuations mean bigger future deductions (arguing for patience), while uncertainty argues for acting now. For most donors, these second-order timing effects are dwarfed by the matching program benefit and the behavioral commitment value.

How Much Is Already in DAFs?

Employee Equity: $20-40B Already Committed

The employee equity pool is estimated at 12-18% of Anthropic ($42-63B at $350B). EA Forum Participation in the matching program varies significantly by cohort:

Central estimate: $20-40B already committed to DAFs through employee matching.

Key facts:

• These commitments are legally binding — equity has been irrevocably transferred to DAFs
• Participation rates are higher among early employees (who had better matching terms and stronger EA connections)
• Some employees may make additional voluntary transfers beyond the matching program, estimated at $1-5B
• The matching source may come from company reserves or a pre-allocated pool, which could overlap with founder equity estimates

Founder Equity: Uncertain but Estimated at $1-8B

All seven co-founders have pledged to donate 80% of their wealth (non-binding). Fortune Their individual equity stakes are uncertain:

Fortune EA Forum

The financial case for founder DAF transfers is the same as for employees (stock donation avoids capital gains, commitment before liquidity reduces behavioral drift). But founders face additional friction: time constraints of running a rapidly scaling company, potential signaling effects to investors, and reasonable preference for flexibility on vehicle choice and cause allocation.

Central estimate: $1-8B in pre-IPO founder DAF transfers (EV ≈$4B). The 90% confidence interval extends from $0 to $15B+. All dollar amounts carry 2-3x uncertainty from the equity stake estimates alone.

Combined Estimate

Employees vs. Founders

Employee capital is both larger and more certain than founder capital. The matching program created a structured financial incentive that made participation rational for employees with any charitable intent, while founders retained full flexibility.

Important Limitations of DAFs

"In a DAF" is not the same as "going to high-impact causes" or even "being deployed soon." The same IPS report cited for Giving Pledge fulfillment data also criticizes DAFs as vehicles:

• No minimum payout requirement. Unlike foundations (5% annual distribution), DAFs can hold assets indefinitely. Money can sit growing tax-free for decades with no obligation to grant it.
• Full donor discretion. DAF donors choose which 501(c)(3)s receive grants. The capital could go to AI safety research, or to the donor's alma mater, or sit idle. There's no mechanism to ensure alignment with any particular cause.
• 501(c)(3) restriction. DAFs can only fund tax-exempt charities — not lobbying organizations, political campaigns, or 501(c)(4) policy organizations like ARI. This excludes a significant fraction of AI governance work.
• Immediate deduction, deferred impact. Donors receive full tax deductions upon transfer, creating a public subsidy for charitable capital that may not reach working organizations for years.

DAF transfers are better than non-binding pledges (the commitment is irrevocable) but weaker than direct grants (immediate deployment to a specific cause). From the EA community's perspective, the $20-40B in employee DAFs is a large pool of capital that is legally committed to charity but not committed to any particular cause or timeline.

Giving Pledge Context

The Giving PledgeOrganizationGiving PledgeThe Giving Pledge, while attracting 250+ billionaire signatories since 2010, has a disappointing track record with only 36% of deceased pledgers actually meeting their commitments and living pledge...Quality: 68/100 provides the closest historical analogy for founder pledges, with an important threshold difference: Giving Pledge signatories commit to 50% of wealth, while Anthropic founders committed to 80%. Fulfillment at the higher threshold would likely be even lower. IPS

Among 22 deceased Giving Pledge signatories, only 8 (36%) met even the 50% threshold. Living original pledgers have grown 166% wealthier in inflation-adjusted terms since 2010. These figures suggest non-binding pledges face serious fulfillment risk, especially for younger donors.

The employee matching program effectively bypasses this risk through structure: by making participation financially attractive (matching) and irrevocable (DAF transfer), it achieves high commitment rates without relying on personal willpower over decades. This structural approach — making good behavior the easy, financially rational choice — is more reliable than moral exhortation.
