PRAGUE — In 2007, a group of Czech guerrilla artists scaled a transmitter tower belonging to the country’s national television station and hacked into a live webcam of the Krkonoše mountain range typically used during the weather segment. In the midst of a live broadcast on June 17 of that year, the rebel collective — dubbed Ztohoven — faked a nuclear bomb detonation. Viewers watched as a camera shot panning across the landscape flashed white and revealed a mushroom cloud in the distance, reminiscent of a war-era newsreel threatening Armageddon.
The stunt was a signature move for the consortium of Bohemian subversives, one among many disruptive pranks over the course of decades designed to provoke onlookers and foster a sense of resistance and revolt against prescribed societal norms. Ztohoven has since added the banner of crypto anarchy to its mantle, embracing the hackers and provocateurs who helped mobilize themovement since its inception.
Today, that union of minds finds refuge in Prague in a retrofitted factory building called Paralelní Polis, or “parallel world.” The name pays homage to Czech philosopher and dissident, Václav Benda, who coined the phrase in the 1970s as a way to describe an emerging underground counterculture quietly subverting the ruling communist regime.
Ztohoven’s parallel world offers a different kind of anarchy. The space functions as a living example of how the world could look — a crucible for decentralized and defiant technologies designed to operate beyond the reach of governments, laws, and central banks.
It’s a place where cryptography replaces control, cryptocurrency supplants fiat, and controversial concepts aren’t just discussed, but are lived ideologies binding people together.
For more than two years, Dan Ligocký has been working from Polis three to five days a week. Ligocký, who is an event producer with deep ties to the ethereum community, tells CNBC that the space has served as a catalyst for innovation and the exploration of decentralized technologies.
“Its commitment to privacy, freedom, and self-sovereignty aligns with the core principles of the Web3 movement,” continued Ligocký. “We’re here to support the ecosystem and are open to collaborating with anyone whose ethos aligns with ours.”
Indeed, the vast factory-turned-forum pulses with the collective energy of digital rights activists, privacy-obsessed cypherpunks, and crypto-faithful ideologues. Its diverse denizens ranging from transient visitors like the Czech prince William Lobkowicz, to ethereum co-founder Vitalik Buterin.
Polis is a place where technology, philosophy, and activism converge.

A tale of two castles
The Czech Republic’s den of crypto anarchy sits in the heart of Holešovice — a district bound by the left bank of the Vltava River to the east and Letná Hill to the west. The neighborhood was once the epicenter of industrial Prague, synonymous with slaughterhouses and steam mills, but today is home to art galleries and ateliers.
At the opposite end of the city in a district called Hradčany — about three-and-a-half miles south-west of Polis — is a 750,000 square foot castle complex that appears frozen in a Renaissance-era alternate dimension. Its imposing Gothic spires loom over the Czech capital — a vestige of a time when inherited nobility meant something quite different to the people of Prague.

Once the seat of Bohemian kings and Holy Roman emperors, Czech presidents now occupy the castle complex — a sprawling massof palaces, churches, towers, hidden passageways, and gardens.
Two young nobles, William and Ileana Lobkowicz, sometimes holdcrypto-centric events there. Neither live at the palace, but they use the stately halls and manors once inhabited by their ancestors for industry working groups on digital assets.
A multi-day annual conference called Non-Fungible Castle is their banner event, and the siblings have also spent the last few years tinkering with using NFTs as a way to fund restoration projects — an ambition that appears to have faded during the bear market as NFT sales and prices plummet.
This summer, however, the Lobkowicz family expanded their crypto outreach efforts by hosting some of the most established coders in the ethereum ecosystem for a one-day working session. The workshops were followed by a private tour of the castle and a multi-course gala dinner in the Imperial Hall at Lobkowicz Palace — an event where the conversation effortlessly shifted from Europe’s groundbreaking new crypto law to the convergence of generative AI and blockchain tech.

The easiest way to get to the palace from Polis is to walk three minutes to the Maniny station, where Tram 25 stops every ten minutes before sweeping passengers up the hill to Prašný Most, which borders the castle grounds. The intricate web of trolley rails traces Prague’s cobblestoned streets, a pattern of steel tracks etched into the old-world urban landscape, while the stoic steel and glass trams serve as a moving tableau of life in Prague.
Although only 25 minutes apart, the two locations represent the split personality of the Czech people.
One side is the storybook Prague most people associate with the city — soaring towers, grand chandeliers, and original frescoes. The other is the secret Bohemian underground that has spent decades thwarting authoritarian regimes. For centuries, the Czech capital has been caught between historic powers with a bent toward world domination, which has helped the populace develop a thick skin and the knowhow to fight back against the world’s biggest villains.

“Czechs are naturally skeptical of authority, a result of the tough 20th century during which Czechs experienced monarchy, Nazi occupation, and communist rule,” said Josef Tětek, a crypto economist and bitcoin analyst at hardware wallet provider, Trezor.
“A prime example of this skepticism is the fact that the Czech Republic never adopted the euro, even though it has been a member of the European Union since 2004,” Tětek added.
Call it the ultimate anti-fairytale.
In this story, the main character isn’t a prince in a high castle, but a decentralized collective of shadowy coders and hackers living in pockets across Prague who sometimes converge on Polis to swap trade secrets and sound a call to action.
The dark stucco of Polis’ Prague headquarters is an outlier among the ornate, brightly-colored buildings that tower over it. The interior of this deceptively nondescript structure is a honeycomb of winding,labyrinthinecorridors and castle-like passageways that stretch endlessly higher and deeper into its fortress-like belly.

The ‘parallel world’ concept is sticky.
Franchises of Polis have sprung up in Vienna, Barcelona, and two Slovak cities — a testament to the enduring allure of anarchy. The Vienna branch goes so far as to self-describe as a living example of how “the Paralelní Polis cryptoliberation virus is spreading.”
These hubs share certain physical features — there are co-working tables for hire, conference halls for hackathons and blockchain-specific meet-ups, as well as spaces dedicated to experimental tech, where you can dabble with 3D printing and laser cuts.
In addition to hosting regular bitcoin and ethereum meetups, the Bratislava chapter also holds sessions dedicated to biohacking — or augmenting the human body with tech custom-engineered to create a new breed of superhumans. On the other side of Slovakia, in Košice, the Polis offers formal lectures and technical support, where locals can drop by for impromptu consultations on how blockchain and cryptocurrencies can support their business.
Another common fixture across these chapters is the so-called Institute of Cryptoanarchy, a sort of sub-franchise that provides free educational resources and classes to people keen to learn more about the unregulated internet, as well as the anonymous tools — blockchain-based virtual currencies and anti-spyware encryption protocols — that can help power a decentralized economy.

The crypto schooling helps with spurring adoption and enlisting more troops to the cause.
Today’s enemy is a little different than the communist and Nazi occupiers of the 20th century. Instead of a military-powered regime, these coders see their rival as a more insidious villain. The Austrian hub characterizes the threat not as a “distant dictatorial world,” but as the way current governments attempt to control the flow of information.
“States and their security agencies globally control access to information and use the protection of intellectual property as an excuse to apply total censorship to control the available resources,” reads part of the mission statement on their website.
Crypto fans descend on Prague
As the U.S. crypto scene is imploding and companies dealing in digital assets face growing scrutiny from regulators, much of the developer community has flocked to international tech hubs like the Czech Republic to seek like-minded coders with a view to stick it to the man — or to at least steer clear of the establishment.
One reason why Prague has become the center of gravity for the industry has to do with its roots in the Austrian school of economics, a concept born out of 19th-century Vienna that remains quite popular in the Czech Republic today.
Carl Menger and Friedrich Hayek helped birth this particular brand of classical economic liberalism — not to be confused with the American concept of political liberalism. It holds independent individuals acting in their best economic self-interest is the optimal way to run a society and create a thriving economy, rather than centralized control or the heavy hand of state intervention.

“Adherents of this school of thought have been writing articles and books on bitcoin for the Czech audience since 2016,” Tětek told CNBC, who went on to note some of the natural synergies between bitcoin believers and economists schooled in Austrian economics.
“The Austrian school is very compatible with bitcoin adoption,” he said. “A central aspect is the call for a separation of money and state.”
Adherents of both worlds do not think the Federal Reserve can rescue the economy. Tětek added that bitcoin as an alternative independent monetary instrument thrives in this environment.
It helps that Prague has a long track record of drawing the sector’s top talent. The Czech capital is home to the world’s first hardware wallet and the first bitcoin mining pool. Bitcoin is accepted in Alza, one of the largest retail chains in the country, as well as in hundreds of other smaller businesses. The city also plays host to major international conferences drawing thousands to Bohemia each year.
“Overall, the bitcoin community in the Czech Republic is very strong, especially when measured per-capita,” said Tětek. “There are around 10 million Czech speakers. The most popular Czech bitcoin YouTuber boasts 90k subscribers, while the annual Czech-only bitcoin conference called Chaincamp attracts around 2000 visitors, even during the bear market.”

“Czechs are natural-born tinkerers; the early bitcoin projects such as Trezor and General Bytes emerged in the Prague hacker scene,” said Tětek, who has a background in Austrian economics and political philosophy. General Bytes is one of the larger bitcoin and crypto ATM manufacturers, which also provides software for Bitcoin ATM operators.
This summer, ETHPrague and BTCPrague held major summits in the capital over the same one-week window. The ethereum event organizers rented out space from Polis, while the bitcoiners descended on Prague’s jumbo-sized expo center at the outskirts of town.
BTCPrague talked a big game on event stats — 100+ speakers across four stages, 100+ companies and open-source projects at the expo, and 10,000+ attendees from all across Europe and beyond. While the venue was sprawling and packed on its first day, CNBC cannot independently confirm attendance numbers.
Some of the most notable names in the bitcoin ecosystem were there, including Microstrategy’s Michael Saylor, suspected Satoshi cryptographer and cypherpunk Adam Back, and best-selling economist and author Saifedean Ammous.

Ancillary events complementing the dual crypto conferences took place across the city.
One was hosted in the private dining room of a steakhouse in Old Town where the merits of bitcoin — and its imminent threats — were debated until midnight. One point in contention: Whether Securities and Exchange Commission Chairman Gary Gensler is a closeted bitcoin maximalist, given it is the one digital asset that he has explicitly omitted from his concerted campaign to police and dismantle the ecosystem.
Meanwhile, ethereum enthusiasts descended on a modern houseboat in Holešovice for a beer tasting by the Czech Craft brewery Václav, where the Czech classic 12° Pils Vaclav and the buttery IPA 17° Sexy Hafanana were both on tap.
Another side event took place one morning at Trezor’s office, a modest space in the SatoshiLabs building located in a remote, residential suburb two miles north-east of Polis. The session included some of Prague’s top bitcoin founders — Matěj Žák, the CEO of Trezor; Jan Čapek, co-founder of Braiins, which proclaims to be the first company to introduce the concept of bitcoin mining pools; Christoph Kassas of General Bytes; and prominent Bitcoin YouTuber Jakub Vejmola. The discussion was more of a lecture-style format, with each of the leaders talking about current expansion efforts during the bear market.
The Braiins team also spoke about how they are bracing for imminent regulation in the space. The team described a protocol in development now that would make it so that pools are not capable of choosing the transactions that comprise each block — that way, they would avoid being blamed for violating any impending rules from the U.S. Treasury restricting the exchange of cryptocurrency.
“This extension to the protocol is essentially managed so that miners can choose their own work templates being approved by the pool, but then basically, the pool as a legal entity is out of the game, in terms of not being responsible for selecting the transaction,” explained Čapek.
A look around the room revealed an audience of a couple dozen people, filled with some of today’s most influential bitcoiners, including technologist and software engineer Jameson Lopp, a cypherpunk and co-founder of bitcoin security provider Casa, as well as the popular podcast hosts Stephan Livera and hedge fund manager-turned-bitcoiner Robert Breedlove.
Across town at Polis, Duct Tape Production put on ETHPrague, in coordination with the Ethereum Foundation.

The multi-day conference drew in the most influential thinkers in the space — including Buterin, one of the most prominent coders on the planet, and Stani Kulechov, founder and CEO of Aave and Lens.
Programming consisted of a mix of lectures and panels on everything from MiCA and self-regulation within decentralized finance, to the nuances of layer two protocols being built on top of ethereum. These working sessions brought together technologists, lawyers, and politicians from across the continent to discuss next steps for the industry.
“I was genuinely surprised at how helpful and friendly the participants were, how much altruism and reciprocity could be felt in their views and presentations, and the fact that they are close to the ‘build homes, not empires’ vision,” said Ondrej Polak, executive director of the newly-founded Czech Blockchain Association, who also describes himself as a practicing technology optimist and AI advocate.

Ligocky had a similar reaction to ETHPrague, saying it reaffirmed his belief that “the future of the internet is being reshaped by a vibrant global community of visionaries, developers, and entrepreneurs.”
“The sense of community and shared purpose was truly inspiring, as we collectively strive to unlock the limitless possibilities that lie ahead in this decentralized frontier,” continued Ligocky.
“ETHPrague is just the beginning,” he said, adding that they’re working on more events across Europe for teams that share the same vision.
Anthropic and Google officially announced their cloud partnership Thursday, a deal that gives the artificial intelligence company access to up to one million of Google’s custom-designed Tensor Processing Units, or TPUs.
The deal, which is worth tens of billions of dollars, is the company’s largest TPU commitment yet and is expected to bring well over a gigawatt of AI compute capacity online in 2026.
Industry estimates peg the cost of a 1-gigawatt data center at around $50 billion, with roughly $35 billion of that typically allocated to chips.
While competitors tout even loftier projections — OpenAI’s 33-gigawatt “Stargate” chief among them — Anthropic’s move is a quiet power play rooted in execution, not spectacle.
Founded by former OpenAI researchers, the company has deliberately adopted a slower, steadier ethos, one that is efficient, diversified, and laser-focused on the enterprise market.
A key to Anthropic’s infrastructure strategy is its multi-cloud architecture.
The company’s Claude family of language models runs across Google’s TPUs, Amazon’s custom Trainium chips, and Nvidia’s GPUs, with each platform assigned to specialized workloads like training, inference, and research.
Google said the TPUs offer Anthropic “strong price-performance and efficiency.”
“Anthropic and Google have a longstanding partnership and this latest expansion will help us continue to grow the compute we need to define the frontier of AI,” said Anthropic CFO Krishna Rao in a release.
Anthropic’s ability to spread workloads across vendors lets it fine-tune for price, performance, and power constraints.
According to a person familiar with the company’s infrastructure strategy, every dollar of compute stretches further under this model than those locked into single-vendor architectures.
Google, for its part, is leaning into the partnership.
“Anthropic’s choice to significantly expand its usage of TPUs reflects the strong price-performance and efficiency its teams have seen with TPUs for several years,” said Google Cloud CEO Thomas Kurian in a release, touting the company’s seventh-generation “Ironwood” accelerator as part of a maturing portfolio.
Claude’s breakneck revenue growth
Anthropic’s escalating compute demand reflects its explosive business growth.
The company’s annual revenue run rate is now approaching $7 billion, and Claude powers more than 300,000 businesses — a staggering 300× increase over the past two years. The number of large customers, each contributing more than $100,000 in run-rate revenue, has grown nearly sevenfold in the past year.
Claude Code, the company’s agentic coding assistant, generated $500 million in annualized revenue within just two months of launch, which Anthropic claims makes it the “fastest-growing product” in history.
While Google is powering Anthropic’s next phase of compute expansion, Amazon remains its most deeply embedded partner.
The retail and cloud giant has invested $8 billion in Anthropic to date, more than double Google’s confirmed $3 billion in equity.
Still, AWS is considered Anthropic’s chief cloud provider, making its influence structural and not just financial.
Its custom-built supercomputer for Claude, known as Project Rainier, runs on Amazon’s Trainium 2 chips. That shift matters not just for speed, but for cost: Trainium avoids the premium margins of other chips, enabling more compute per dollar spent.
Wall Street is already seeing results.
Rothschild & Co Redburn analyst Alex Haissl estimated that Anthropic added one to two percentage points to AWS’s growth in last year’s fourth quarter and this year’s first, with its contribution expected to exceed five points in the second half of 2025.
Wedbush’s Scott Devitt previously told CNBC that once Claude becomes a default tool for enterprise developers, that usage flows directly into AWS revenue — a dynamic he believes will drive AWS growth for “many, many years.”
Google, meanwhile, continues to play a pivotal role. In January, the company agreed to a new $1 billion investment in Anthropic, adding to its previous $2 billion and 10% equity stake.
Critically, Anthropic’s multicloud approach proved resilient during Monday’s AWS outage, which did not impact Claude thanks to its diversified architecture.
Still, Anthropic isn’t playing favorites. The company maintains control over model weights, pricing, and customer data — and has no exclusivity with any cloud provider. That neutral stance could prove key as competition among hyperscalers intensifies.
Redwood Materials, founded by former Tesla CTO and cofounder JB Straubel, has raised $350 million in new funding to scale its US-made battery storage systems and critical materials operations. The company is ramping up to meet surging demand from AI data centers and the clean energy sector.
The oversubscribed Series E round was led by Eclipse, with participation from NVentures, NVIDIA’s venture capital arm, and other new strategic investors.
As global supplies tighten, the US is racing to secure domestic production of critical materials like lithium, nickel, cobalt, and copper. In July, Redwood and GM signed a non-binding memorandum of understanding to turn new and second-life GM batteries into energy storage systems. Redwood launched a new venture in June called Redwood Energy that repurposes both new and used EV battery packs into fast and cost-effective energy storage systems.
Redwood says large-scale battery storage is the fastest and most scalable way to enable new AI data center rollout while unlocking stranded generation capacity and stabilizing the grid. Battery storage also helps industrial facilities electrify and balance renewable energy output. The company aims to deliver a new generation of affordable, US-built energy storage systems designed to serve the grid, heavy industry, and AI data centers, reducing dependence on imported Lithium Iron Phosphate batteries.

Redwood will use the new capital to expand energy storage deployments, refining and materials production capacity, and its engineering and operations teams.

A report this morning detailed American EV automaker Rivian’s plans to lay off a portion of its current workforce as it tries to conserve cash while gearing up for the launch of its newest model, the R2, next year.
Update 10/23/25: As promised, Rivian followed up with more details of this morning’s report regarding layoffs. The following letter from Rivian founder and CEO, RJ Scaringe, was sent out to the automaker’s workforce moments ago:
Hi Team,
I am writing to share a difficult update.
With the launch of R2 in front of us and the need to profitably scale our business, we have made the very difficult decision to make a number of structural adjustments to our teams. These changes result in a reduction in the size of our team by roughly 4.5%.
These are not changes that were made lightly. With the changing operating backdrop, we had to rethink how we are scaling our go-to-market functions. This news is challenging to hear, and the hard work and contributions of the team members who are leaving are greatly appreciated.
To ensure we move forward with clarity, I want to summarize the areas most impacted.
Streamlining the Customer Journey: To provide a seamless experience for our customers, we are integrating the Vehicle Operations workstreams into the Service organization to create fewer customer handoffs and clearer ownership. We are also integrating the Delivery and Mobile Operations into the Sales organization to ensure the purchase experience is as seamless as possible with a single touchpoint throughout the entire sales process and to delivery.
Elevating Our Marketing Efforts: Historically we have had multiple functions that collectively capture what would typically be housed in a single marketing organization. We have made the decision to form a single marketing organization, and while we recruit our first Chief Marketing Officer (CMO), I will be acting as Interim CMO. Our Marketing Experiences team, led by Denise Cherry, and the Creative Studio team, led by Matt Soldan, will both report directly to me for now.
These changes are being made to ensure we can deliver on our potential by scaling efficiently towards building a healthy and profitable business. I am incredibly confident in R2 and the hard work of our teams to deliver and ramp this incredible product.
Thanks again everyone.
RJ
Not much backstory here, so we’ll get right into it.
A report from the Wall Street Journal this morning shared brief details of Rivian’s layoff plans, which could affect approximately 4% of the current staff. At the end of 2024, Rivian’s workforce tally sat around 15,000 people, so the reported layoff could affect as many as 600 individuals, possibly more.

Other outlets have pointed out that EV automakers like Rivian have faced a tougher market following the end of the $7,500 federal tax incentive. While that may be true to a certain extent, most of Rivian’s R1 variants didn’t qualify, unless it was a lease, and the automaker has deployed its own incentive programs.
In fact, Rivian’s Q3 2025 deliveries exceeded expectations. It remains speculative at this point until we receive an official statement from Rivian explaining the plans to lay off staff, but this could be a preemptive decision based on market forecasts.
Furthermore, Rivian is closer than ever to launching R2 in 2026, which has the makings of becoming a bestseller in the EV industry if sales match a mere portion of the hype surrounding it. The layoffs could also be a lean-down to conserve funds through the home stretch of that development process before beefing back up again in 2026 or 2027 when demand is (ideally) higher.
We really do not and will not know the reasoning behind the decision until Rivian shares more information.
We reached out to Rivian for comment and were told the automaker will have more to share this afternoon. We will update this story as new information becomes available.
