Greg Brockman and his wife donated $50 million to two politically opposed super PACs in one filing day last September — but the macro story is the AI employee donor class that's outpacing Google, Facebook, and Airbnb before a single lab has gone public.

OpenAI President Greg Brockman and his wife Anna donated $12.5 million each to two super PACs on September 12, 2025 — one to MAGA Inc., Donald Trump's principal super PAC, and one to Leading the Future, a bipartisan PAC organized to oppose state AI regulation — bringing their household total to $50 million in a single filing day, per FEC records. Brockman listed his employer as OpenAI on both itemized contributions. His entire federal giving prior to that date on record: $2,700 to Hillary Clinton in 2016, per Notus.

Those two filings sit at the megadonor end of an AI political money map that turns out to be much wider. The structural story is the Anthropic employee — four levels below the C-suite, giving the campaign maximum — doing it at rates that would make any party operative's ears prick up.

An analysis by The San Francisco Standard, published Friday and based on FEC itemized contributions through July 15, 2026 and California state filings through the June primary, puts Anthropic employees at a federal donor participation rate of roughly 59 per 1,000 workers — nearly triple Airbnb's 21.9 per 1,000 in its first post-IPO midterm cycle, and more than four times Google's 10.2 and Facebook's 13.4 in their equivalent periods. OpenAI's rate of 23 per 1,000 still clears all three historical benchmarks. Inflation-adjusted, AI-lab employees are outgiving those prior cohorts more than threefold, even excluding Brockman's contributions. (Employee headcounts used as denominators: OpenAI at approximately 4,000, per the Wall Street Journal; Anthropic at approximately 3,000, per the New York Times.)

The intensity matches the breadth. Nearly 39% of Anthropic's federal donors have given the legal maximum to at least one candidate, more than double Airbnb's comparable share in its first post-IPO cycle, per the Standard's analysis. In one documented transaction from last fall, 28 Anthropic and OpenAI employees gave congressional candidate Alex Bores a combined $173,000 in a single day — 24 of the 28 writing the $7,000 campaign maximum. Two days later, 17 of those same donors contributed to California State Sen. Scott Wiener's congressional campaign, per the Standard.

Leading the Future — the anti-regulation PAC that received half of Brockman's $25 million in his own name — reported $50.3 million in total receipts and $39.3 million in cash on hand as of December 31, 2025, per FEC filings. Marc Andreessen and Ben Horowitz each put another $25 million into the same PAC, per Transformer News AI's analysis of FEC data. The PAC has spent on congressional primaries across both parties and run advertising against state AI legislation. An affiliated 501(c)(4), Build American AI, was caught operating anonymous social-media accounts, a scheme reported by journalist Taylor Lorenz and the Midas Project; OpenAI denied funding the group. That denial was contradicted on the record by Build American AI's own executive director, Nathan Leamer, who named OpenAI as one of four corporate funders, per Transformer News AI.

At the other end of the map: Anthropic CEO Dario Amodei donated $1 million personally to Public First PAC (FEC ID: C00930503), an AI-safety-aligned super PAC, on May 4, 2026, per FEC filings first reported by Politico.

None of this has touched IPO liquidity. Anthropic and OpenAI have not filed S-1s as of this writing. The donor rates documented through July 15 are built entirely on salaries and tender-offer proceeds — not the equity wave the market is waiting on. What happens to these figures when employees can actually sell their shares is the variable this analysis, by design, cannot yet measure.
