$503 billion. That's what Biden's Treasury said its 25% minimum tax on the very rich, unrealized gains included, would raise over 10 years. Marc Andreessen called it "the final straw" and backed Trump. It never passed.
This PolicyBomb grades the policies Andreessen, Ben Horowitz and Elon Musk named, not the people.
So what was in the tax? Net wealth over $100 million. And a carve-out: founders whose tradeable assets were under 20% of their wealth could defer, with the charge capped at 10% of gains, and private stock was valued at the last funding round, not a yearly appraisal. The claim it would "absolutely kill" startups and venture capital: Overstated.
Crypto: Biden's SEC brought a record 47 crypto cases in 2023 and 33 in 2024. But $4.55 billion of the $6.05 billion recovered in the Gensler era came from one collapse, Terraform Labs. Real fraud. Congress voted to overturn the SEC's SAB 121 custody rule, 228 to 182 in the House and 60 to 38 in the Senate. Biden vetoed it, and the override failed 228 to 184. "Brutal assault": Partly substantiated.
AI: Biden's order made developers of models trained above 1026 operations report to Commerce. Reports, not licenses. "OPEC of AI": Overstated. Andreessen's account that officials said they would "classify any area of math" comes from private meetings and is Unverified. The order was rescinded on Jan 20, 2025.
Musk said California's AB 1955, a school gender identity notification law, was his "final straw," moved SpaceX and X to Texas, and spent $277 million backing Trump and Republicans, $239 million of it to America PAC (FEC filings, via CBS News). This PolicyBomb does not grade AB 1955 itself.
What they got: a stablecoin law, the GENIUS Act, 68 to 30 in the Senate and 308 to 122 in the House, signed July 18, 2025. What came with it: a $100,000 payment on new H-1B petitions and a 2025 tax and spending law CBO says adds $3.4 trillion to the debt (CBO estimate as reported by ABC News). It passed the House 218 to 214, with Republicans Thomas Massie and Brian Fitzpatrick voting no, after Vice President JD Vance broke the Senate tie. Musk's word for it: "a disgusting abomination."
Verdict: MIXED. Real grievances, oversold threats, and a bill that came due.

Executive finding
In July 2024 Marc Andreessen and Ben Horowitz endorsed Donald Trump on three stated grounds: taxes, AI and crypto. [1,2] Elon Musk, separately, called California's AB 1955 "the final straw" and moved SpaceX and X headquarters to Texas, then spent $277 million backing Trump and Republicans. [3,12] Tested against official text and data, the grievances were real on paper but the threats were oversold. The tax Andreessen called "the final straw" was a Treasury proposal worth $502.7 billion over ten years that Congress never enacted, and it already contained an "illiquid" election for founders. [5] Crypto enforcement did hit a record in 2023, but most of the money recovered came from one collapse, Terraform Labs. [11] After the 2024 election their side delivered on AI and crypto, and also enacted a law CBO says adds $3.4 trillion to the debt, which Musk called "a disgusting abomination." [13,14] Verdict: MIXED.
1. What is the policy?
This PolicyBomb examines the specific policies Andreessen, Horowitz and Musk cited, not a single bill.
Policy A: Minimum income tax on the wealthiest taxpayers (Treasury FY2025 Green Book)
- A 25% minimum tax on "total income, generally inclusive of unrealized capital gains," for taxpayers with net wealth above $100 million, fully phased in above $200 million. [5]
- First-year liability payable in nine annual installments; later years in five. [5]
- Tradable assets valued at year-end market prices. Non-tradable assets valued at the greater of cost basis or "the last valuation event from investment, borrowing, or financial statements," growing between valuations at the five-year Treasury rate plus two points. [5]
- Taxpayers whose tradeable assets are under 20% of wealth may be treated as "illiquid" and include only gains on tradeable assets; non-tradeable gains then bear a deferral charge at realization that "would not exceed ten percent of unrealized gains." [5]
- Treasury revenue estimate: $502,668 million over FY2025 to 2034. [5]
- Status: budget proposal; not enacted.
Policy B: SEC crypto enforcement and SAB 121
- SEC Staff Accounting Bulletin 121 required custodians to book client crypto as a liability, which critics said blocked bank custody. H.J.Res.109 (sponsor Rep. Mike Flood, R-NE) disapproved it: House 228 to 182 (May 8, 2024), Senate 60 to 38 (May 16, 2024), vetoed May 31, 2024; override failed 228 to 184 (July 11, 2024). [6]
- Enforcement counts (Cornerstone Research via The D&O Diary): 47 crypto actions in 2023 (record), 33 in 2024; 125 under Chair Gary Gensler vs 70 under Chair Jay Clayton. [11]
Policy C: AI Executive Order 14110 (Oct 30, 2023)
- Section 4.2 required developers to report to Commerce on models trained with more than 1026 operations (1023 for biological sequence data) and on large computing clusters, including red-team results. [9]
- Rescinded by EO 14148 on January 20, 2025. [10]
Policy D: California AB 1955 (Musk)
- Musk on X, July 2024: "This is the final straw. Because of this law and the many others that preceded it, attacking both families and companies, SpaceX will now move its HQ from Hawthorne, California to Starbase, Texas." He added X would move to Austin. [3]
- This pack records the stated reason and the move; it does not evaluate AB 1955 itself (Unverified here).
Other Musk positions
Fortune (Nov 6, 2024) documents Musk's areas of agreement and difference with Trump, including tariffs: he criticized tariffs on Chinese EVs in May 2024 and later said Tesla needs tariffs to compete. [4]
2. Why do these policies exist?
Stated reasons
- Treasury: preferential treatment of unrealized gains "provides many high-wealth taxpayers with a lower effective tax rate than many low- and middle-income taxpayers" and creates lock-in. [5]
- SEC: case-by-case enforcement under existing securities law, since Congress had not passed a crypto statute. [11]
- EO 14110: safety reporting on the largest frontier models. [9]
The critics' stated reasons
- Little Tech Agenda: regulation written by incumbents ("regulatory capture") hurts startups; unrealized gains tax "would absolutely kill both startups and the venture capital industry that funds them"; call for more high-skilled immigration. [1]
- Andreessen on the tax: founders' wealth is illiquid but the tax is due in cash, so they would be "forced to repeatedly sell off slices of equity," per Fortune's paraphrase; "This makes startups completely implausible." [2]
- On crypto: "a brutal assault on a nascent industry." On AI: "an OPEC of AI." [2]
3. What has it actually done?
Testing the claims
| Claim | Test | Finding |
|---|---|---|
| Unrealized gains tax would kill startups and VC [1] | Green Book text: illiquid election, deferral charge cap 10%, valuation at last funding round, installments [5] | Overstated. Real valuation and cash costs for founders above $100 million, but the forced-sale scenario is softened by the text; never enacted |
| Tax was a threat to "founders" broadly [2] | Threshold $100 million net wealth, full at $200 million [5] | Partly substantiated. Hits only very wealthy founders; count of affected founders Unverified |
| "Brutal assault" on crypto [2] | 47 actions in 2023 (record); 125 Gensler vs 70 Clayton [11] | Partly substantiated. Volume rose; $4.55 billion of $6.05 billion recoveries came from Terraform Labs, a real investor loss case [11] |
| Biden blocked bipartisan crypto custody fix [2] | H.J.Res.109 passed both chambers, vetoed, override failed [6] | Substantiated |
| "OPEC of AI" [2] | EO 14110 required reporting above 1026 operations, no licensing [9] | Overstated as to the order's text |
| "We will classify any area of math" [2] | Andreessen's account of private meetings | Unverified |
What changed after the 2024 election
- AI: EO 14110 rescinded January 20, 2025. [10]
- Crypto: GENIUS Act (S.1582, sponsor Sen. Bill Hagerty, R-TN) passed the Senate 68 to 30 (June 17, 2025) and House 308 to 122 (July 17, 2025); signed July 18, 2025 as Public Law 119-27. [7,8] SEC crypto action counts for 2025: Unverified (a Cornerstone 2025 update could not be retrieved).
- Banking: Executive Order "Guaranteeing Fair Banking for All Americans" (August 2025) addresses "Reputation Risk and Politicized or Unlawful Debanking" and cites "Operation Chokepoint." [17] Number of debanked founders: Unverified.
- Immigration: a September 2025 proclamation requires a $100,000 payment with new H-1B petitions, subject to exceptions. [16] This runs against the Little Tech Agenda's high-skilled immigration plank. [1]
- Fiscal: the 2025 tax and spending law passed the House 218 to 214; CBO estimated it adds $3.4 trillion to a $36.2 trillion debt (CBO estimate as reported by ABC News). [14,15] Musk, June 3, 2025: "This massive, outrageous, pork-filled Congressional spending bill is a disgusting abomination." [13]
Unintended consequences
- The minimum tax was never enacted, so its claimed harm to startups never occurred; startup formation effects are therefore untestable.
- The 2025 tax and spending law that followed adds $3.4 trillion to the debt, per CBO as reported by ABC News, and was not offset. [14] That is a separate law measured on a separate basis from the Treasury revenue estimate for the never-enacted minimum tax. [5]
Eligibility groups
The H-1B payment applies to new nonimmigrant specialty occupation petitions; it does not affect citizens or lawful permanent residents directly. [16] The minimum tax would have applied to U.S. taxpayers above the wealth threshold. [5]
4. Is it good or bad for society?
The strongest case for the critics
They named real policies with real text: a written proposal to tax unrealized gains above $100 million, a record enforcement year without a statute, and a vetoed bipartisan fix. [5,6,11] Moving crypto into a statute passed with bipartisan votes is a better rule of law outcome than case-by-case enforcement. [7,8]
The strongest case against
The headline threats were bigger than the documents. The tax had a founder carve-out and never passed. [5] Most crypto recoveries came from a fraud collapse. [11] The AI order required reports, not licenses. [9] And the agenda they backed delivered a $100,000 H-1B charge and $3.4 trillion more debt. [14,16]
Direct verdict
MIXED. Grievances: real. Threats: oversold. Results: wins on AI and crypto, losses on immigration and debt.
Fiscal and integrity notes
- Fiscal sustainability: CBO's $3.4 trillion estimate is the largest number in this file. [14]
- Fraud, waste and abuse: Terraform Labs accounts for $4.55 billion of Gensler-era recoveries. [11] The use of $40.5 million paid by America PAC to an entity tied to Musk is described as unclear by CBS; no wrongdoing is alleged here. [12]
Named politicians and parties
| Person | Party | Position | Source |
|---|---|---|---|
| Joe Biden | D | Proposed minimum tax; vetoed H.J.Res.109 | [5,6] |

| Kirsten Gillibrand, Angela Alsobrooks | D | Yes, GENIUS Act | [8] |
| Elizabeth Warren, Bernie Sanders | D, I | No, GENIUS Act | [8] |
| Josh Hawley, Rand Paul | R | No, GENIUS Act | [8] |
| Thomas Massie, Brian Fitzpatrick | R | No, 2025 tax and spending law (House 218 to 214) | [15] |
| JD Vance | R | Senate tie-breaking vote for the 2025 law | [14] |
Note: the Senate roll call page lists senators by surname; first names and party labels for Lummis and Moran were added by PolicyBombs.
What a good policy would include
- Taxing the very wealthy without annual private appraisals. Tax gains at death or apply a capped deferral charge at sale for private stock, as the Green Book's illiquid election already does. [5] Revenue for a narrower design: Unverified (no CBO or JCT score fetched).
- Crypto by statute. Extend the GENIUS Act approach to market structure; keep fraud enforcement on Terraform-type cases. [7,11] Cost: Unverified.
- AI transparency by statute. Public, reviewed reporting thresholds like the 1026 operations line, set by Congress rather than by executive order that the next president can rescind. [9,10]
- High-skilled immigration with fees tied to wages, not a flat $100,000. [16] Effect on petitions: Unverified.
- Pay for tax cuts. The 2025 law's $3.4 trillion addition to debt was not offset. [14]
Gaps and Unverified items
- 2025 SEC crypto enforcement counts (a Cornerstone 2025 update could not be retrieved).
- "Classify any area of math" quote (private meeting account).
- Number of founders above $100 million net wealth; number of debanked tech founders.
- Andreessen's own political spending in 2024: not reviewed in this PolicyBomb.
- Effects of AB 1955: not evaluated.

Accountability Scorecard
MixedPolicy #79 grade: Mixed. MIXED. Real grievances, oversold threats, and a bill that came due. The $503 billion unrealized gains tax never passed and already let founders defer; the 2023 crypto enforcement record was real, and so was the Terraform fraud; the 2025 tax and spending law adds $3.4 trillion to the debt per CBO (as reported by ABC News).
Measured outcome: $503 billion: Treasury FY2025 10-year estimate ($502,668 million, FY2025 to 2034) for a 25% minimum tax on income including unrealized gains, wealth over $100 million. Never enacted.

How we grade
Grades come from the "good or bad for society" verdict (question 4) in each PolicyBomb research pack and rest on measured outcomes, not motives. Harmful means the research found net harm, Mixed means real benefits and real costs, Helpful means net benefit. Every name is tied to a documented action (an authored bill, a signature, a recorded vote, a filed donation, an order or a public statement) with a linked source. Only full scorecard rows count toward a person's Harmful, Mixed and Helpful tally; positions listed from the research are shown with their source but are not tallied yet.
