Byron Donalds wants to be Florida's next governor, and he wants you to know he's serious about taxes. On Thursday, Americans for Tax Reform announced Donalds had become the first candidate in the Florida governor's race to sign Grover Norquist's Taxpayer Protection Pledge, the sacred document of supply-side orthodoxy that has ended careers and launched primaries for thirty-odd years. That's the news. Here's what else is on the public record.
The Pledge, the Race, and the Positioning
Donalds is running for the seat Rick Scott vacated when Scott ran for Senate. Florida governors can't raise taxes under the pledge's terms. Signing first is a smart play in a Republican primary where the base treats any whiff of tax flexibility as a disqualifying offense.
On Bluesky, the conversation around Donalds this week has been less about the pledge and more about his other positions: defending hyperscale data centers against local protests, calling small-business state grants a "moral hazard" and a "never-ending cycle" he'd wind down, and the familiar story of right-wing money flowing into his race. The pledge just handed him a clean news cycle. He'll take it.
Here's What Blind Trust Knows About His Financial Record
Three trades filed in the last 90 days. Per the disclosure record on Blind Trust, Donalds purchased Zoetis ($ZTS, $1,001-$15,000) on June 9, then sold Cadence Design Systems ($CDNS, $1,001-$15,000) and Monolithic Power Systems ($MPWR, $1,001-$15,000) on June 5. All three in the same narrow dollar band that tells you the range but not the actual number. That's how congressional disclosures work: you get the bracket, not the receipt.
Zoetis makes animal-health drugs. Cadence makes chip-design software. Monolithic Power makes power-management semiconductors. Three different sectors. No obvious thematic thread. No vote-trade overlaps in the public data for any of these positions.
The Broader Alpha Record
Blind Trust has scored 30 of Donalds's trades for 30-day alpha against the S&P 500. The record: 12 positive, 18 negative. Mean 30-day alpha across the full sample is negative one percent. Not a winning streak. Closer to random with some drag.
The best single trade in the scored sample was a purchase of Marvell Technology ($MRVL) on April 2, 2026, in the $1,000-$15,000 range, which posted 46.6% alpha over the following 30 days. That one belongs in the committee-overlap column: Donalds sits on the House Financial Services Committee's Digital Assets, Financial Technology, and Artificial Intelligence subcommittee, and Marvell is squarely a semiconductor and AI-infrastructure play. The committee overlap is real. What you make of it's your business.
The second-best committee-overlap trade: a purchase of ServiceNow ($NOW) on February 10, 2026, tagged to the same Technology overlap, at plus 11.7% alpha. PayPal ($PYPL) shows up twice in the committee-overlap trades: a sale in February 2026 (minus 0.3% alpha) and a purchase in March 2026 (plus 1.5% alpha). He sold, then bought the same stock a month later. The net result on PayPal rounds to flat, which is at least consistent.
The worst trades: selling The Trade Desk ($TTD) on January 8, 2026 (minus 27.9% alpha), selling it again on March 20, 2026 (minus 21.4% alpha), and selling Intuit ($INTU) on April 2, 2026 (minus 17.8% alpha). Selling a stock twice and watching it run both times is not a great look for the portfolio, but it's also well within what the data calls random noise at these bracket sizes.
Twelve out of thirty is the number. That's the record. The receipts are public.
The Votes
Donalds has been on the floor. Recent votes include a Yea on the Main Street Capital Access Act (passed July 21), a Yea on the Protecting Privacy in Purchases Act (passed July 14), and a full slate of National Defense Authorization Act amendment votes on July 22.
The Main Street Capital Access Act carries an 80 market-relevance score in the data. Donalds sits on Financial Services, which is exactly the committee whose remit covers capital-access legislation for small businesses. He voted Yea. The bill passed. No trade in the disclosure record sits close enough in time to that vote to create a legible overlap in the data.
On the NDAA, he voted Yea on the final bill and on amendments covering military chaplain protections and a ban on automated speed cameras on military installations, and Nay on an amendment expanding investor-access provisions under the NDAA framework. The Nay is the interesting one: an amendment to let more cleared investors into certain program opportunities, which he voted against, and which failed. He's on the Oversight Committee's Military and Foreign Affairs subcommittee, so the NDAA votes sit closer to his committee world than most floor business. Still not a trade-overlap situation by the data.
The Bigger Picture on the Governor's Race
Donalds has been explicit about the data-center question: he told protesters that yes, some hyperscale That's a position with direct implications for energy infrastructure companies, utilities, and the semiconductor supply chain he's been buying into. It's also just Florida development politics, which has its own long tradition of elected officials holding views convenient to the industries building things in their state.
He's also on record wanting to end state small-business grant programs, calling them a moral hazard. The Main Street Capital Access Act he voted for this month works in the opposite direction: expanding capital access for small businesses through federal programs. Whether those two positions are in tension or just operating on different levels of government is a question he'll have to answer on the campaign trail, not here.
The Taxpayer Protection Pledge locks him in on the tax side. The financial disclosure record shows where his personal money has been sitting. Neither tells you what kind of governor he'd be. Both are public documents. The full record is on Blind Trust. Make of it what you make of it.
