Mike Brock

Chief Executive Officer of TBD, Block

Search every verified Mike Brock interview, podcast appearance, and on-the-record quote — each transcript cross-checked by AI and human review to confirm speaker identity. Mike Brock, the former CEO of TBD at Block, has become a full-time political writer and commentator on his Substack, "Notes from the Circus," and through frequent appearances on other podcasts and live streams. In late 2025, he has been a vocal critic of the Trump administration, describing its actions as lawless and accusing figures like Donald Trump and JD Vance of undermining democratic institutions. He has characterized the political right as a coalition that includes what he calls fascists and has called Republican members of Congress who do not oppose the administration "cowards." Brock has also commented on specific events, such as the shooting of two National Guardsmen near the White House, which he described as a potential rallying cry for political repression. In his professional capacity, Brock has continued to advocate for Bitcoin as an "open protocol for money" and a tool for pricing political risk. At Block's Investor Day in December 2025, he discussed the company's strategy for entering the Bitcoin mining hardware market, arguing that the current market is dangerously centralized and that Block's expertise in hardware design gives it a competitive advantage. He has also expressed skepticism about the idea that Bitcoin will replace state currencies, stating that he believes some elasticity in money supplies is important for advanced economies. Brock has described himself as a liberal and a proponent of democracy, and has stated that he left his role in the crypto industry because staying would have meant surrendering his values.

Notable quotes

“Government is the greatest social institution that humans have ever created, right? It is the basis of civilization, right?”

“I don't think we should get rid of debt backed money like I think that's an insane proposition. Um I think John Maynard Kanes was correct actually in his in his rebuttal.”

“We've created an economy that's functioning — humans are adaptive. People have figured out ways to survive by engaging in the gig economy, driving for Uber and DoorDash, but that's not going to last very much longer with these self-driving cars.”

“These guys are attempting a regime change in full public view. They want to bring on 20,000 masked thugs and deploy them across the United States and disappear people, kick down doors without individualized warrants in violation of the Fourth Amendment of our Constitution's Bill of Rights.”

“What we are seeing is an attempted slow-motion coup perpetrated by the current occupant of the executive branch — Donald J. Trump, his vice president JD Vance, and assorted oligarchs. They represent an existential threat to the republic.”

“The idea that we should have immutable algorithms that define the contours of our economy or law — things nobody can change — is epistemically authoritarianism; what if we're wrong about 21 million bitcoins and then we can't change it?”
