Locals blindsided by Trump's secretive plans for public lands: 'Unholy alliance'

Locals blindsided by Trump's secretive plans for public lands: 'Unholy alliance' September 18, 2026 7:23AM ET The Trump administration is quietly working to hand over vast stretches of America's public lands to billionaires and technology companies - and the scale is bigger than known, according to a Friday investigation by The Washington Sun. According to locals who would be affected, they have been kept completely in the dark. The Bureau of Land Management is reviewing at least "12 data center and infrastructure proposals covering more than 17,600 acres" across six Western states - Arizona, Idaho, Nevada, Oregon, Utah and Wyoming - the outlet reported, citing public right-of-way records. Many of the proposals have never been publicly disclosed and aren't easily found on BLM's own website. In Utah, nuclear startup Valar Atomics is reportedly pushing two data centers powered by small nuclear reactors, including a sprawling 10,200-acre site near Green River. Arizona has four proposed projects that could gobble up more than 3,000 acres of public land. The catch: local officials in several states told the Sun they had no idea the deals were even on the table, raising transparency concerns among conservation advocates. According to Lexi Tuddenham, executive director of HEAL Utah, an environmental advocacy group, no one saw this coming. "It's really, really hard to find information about this stuff, and I think it's representative of the way the industry in general is operating with a lack of transparency that I think is really deeply concerning," she told the Sun. "Both the AI industry and the nuclear industry, which seem to be in this unholy alliance right now." "If there are places where communities think it is appropriate to build data centers, focus on those," Aaron Weiss, director of the Center for Western Priorities, told the Sun. "The Trump administration needs to stop cutting the public out of public land management. The solution is more public notice and more opportunities for stakeholders to shape projects on the front end." It's the latest flashpoint in Trump's AI infrastructure push, which has already sparked fury after the administration moved to gut public comment periods on data center pollution permits. Polling shows 70% of Americans oppose data centers landing in their backyards, yet the buildout barrels forward, often in the dark. For customer support contact [email protected].

Utah's deep-tech companies take center stage.

Utah's deep-tech companies take center stage. Recent deals in AI, robotics, medtech and nuclear are pushing the state well beyond its software roots. // Sept 4, 2026 This story appears in the September 2026 issue of Utah Business. Subscribe. Utah's technology landscape continues to move beyond its traditional software roots, with recent investment activity highlighting the state's growing presence in artificial intelligence, robotics, healthcare technology, entertainment software and advanced nuclear energy. Xenter raises $58.25M to accelerate TechMed platform. Draper-based Xenter closed a $58.25 million Series B financing on June 30, which the company announced in July. The company is developing what it calls a TechMed platform at the intersection of medical devices, healthcare data, wireless connectivity and artificial intelligence. The financing attracted existing shareholders, family offices and healthcare-focused investors. The company plans to use the new capital to support the commercial launch of its diagnostics business, expand manufacturing, advance clinical and regulatory initiatives and continue development of its Physical Intelligence platform. Quantizr raises $5M to bring AI to live entertainment. Park City-based Quantizr announced a $5 million seed round led by TTV Capital, with participation from music industry veterans Jonathan Azu, Chris Kappy and Andy Levine. Quantizr is building an AI-powered financial operations platform for the live entertainment industry, automating many of the manual processes involved in managing tours, budgets, expenses, contracts and settlements. The company's approach is notable in an industry where much of the AI conversation has focused on concerns about replacing creative work. Rather than using AI to replace artists, Quantizr is applying the technology to the business infrastructure surrounding them, which allows managers and teams to spend less time on administrative work and more time supporting artists and live experiences. Peppy raises pre-seed to make robotics more accessible. Salt Lake City robotics startup Peppy closed a pre-seed financing led by Element Ventures, with participation from Rock Creek Capital, Mana Ventures and Colin Gardiner of Yonder. The company did not disclose the size of the round. Peppy is developing what its founders call the "Lovable for Robotics," a platform designed to make robotic programming dramatically more accessible. Users can provide text prompts and generate working robotic code that can be tested in simulation and deployed in the physical world. Fluidx Medical Technology advances next-generation embolics. Salt Lake City-based Fluidx Medical Technology also announced the closing of a financing to support development and growth across its medical-device portfolio. The company did not disclose the size of the financing. Fluidx is developing embolic technologies for vascular and neurovascular applications. The new capital follows completion of the GPX IDE clinical trial and continued advancement of its ULTRA platform, while supporting development of IMPASS, a next-generation neurovascular embolic technology. Valar Atomics brings $1B nuclear bet to Utah. The biggest announcement with a significant Utah connection came from Valar Atomics, which closed a $1 billion Series B led by Sequoia Capital, alongside a $200 million credit facility led by Erebor Bank and supported by J.P. Morgan, Crescent Cove and Hercules Capital. Valar is headquartered in El Segundo, California, but its second campus and first small modular nuclear reactor are located in Orangeville, Utah, at the San Rafael Energy Labs. The company is pursuing a vertically integrated approach to nuclear power and recently achieved the first active SMR outside of a national lab at its Ward 250 reactor in Orangeville in June. Valar has also demonstrated the reactor generating electricity to power an NVIDIA Blackwell system and announced plans with NVIDIA for a waterless 30 MW AI factory. Deep tech on the rise. August's activity reinforces a broader shift in Utah's technology economy, but the sector mix is particularly interesting. The state's innovation story is increasingly moving from software alone to the intersection of software, AI, physical technology, energy and life sciences. AI is showing up as an enabling technology across different industries rather than as a standalone category, while life sciences and advanced technologies are attracting larger pools of capital. Particularly of note is the Valar raise. While this article series strives to capture deals headquartered in Utah, the Valar deal is flowing large amounts of capital into the state, putting us at the cutting edge of energy development and making us a leader in nuclear development. Angela Smith is the COO of the Nucleus Institute, Utah's hub for innovation.

Valar raises $1B - A critical reactor still has to prove it can make power.

Valar raises $1B - A critical reactor still has to prove it can make power. On August 4, Valar Atomics disclosed that it had closed a $1 billion Series B led by Sequoia Capital, alongside a $200 million credit facility. The company's financing announcement said the equity would support a shift from demonstrating one integrated reactor system to manufacturing and operating fleets. In its August 4 newsletter, Axios reported a $6 billion post-money valuation and named Atreides Management, Point72 and Snowpoint Ventures among the participating investors. That valuation prices expectations about repeatable reactor production and commercial energy sales - not merely the nuclear-physics milestone Valar has already reached. The round is confirmed; the valuation remains externally reported. The financing itself now has independent confirmation. TechCrunch reported the $1 billion equity round, Sequoia partner Shaun Maguire's appointment to Valar's board and the $200 million credit line. It also noted that Valar did not disclose its valuation, making the $6 billion figure a reported term rather than a number published by the company. The distinction matters because equity and debt finance different parts of the buildout. The Series B gives Valar risk capital for engineering, manufacturing and deployment, while the credit facility adds borrowing capacity. Neither amount establishes that future reactors can be produced on schedule, operated economically or converted into a dependable revenue-generating fleet. Criticality proved the chain reaction, not a power business. Ward 250 reached a precise and important milestone on June 18 at the San Rafael Energy Lab in Emery County, Utah. The Department of Energy described the test as a zero-power fueled criticality demonstration: the reactor sustained a controlled nuclear chain reaction, a condition that must be achieved before power generation. Zero-power criticality is evidence about the reactor core's neutron behavior. It shows that the fueled system can become self-sustaining and controlled under test conditions. It does not, by itself, demonstrate sustained thermal output, efficient conversion of heat into electricity, reliable operation at a specified capacity or delivery of power under a commercial contract. Ward 250 subsequently moved beyond the zero-power test. During a July 1 demonstration in Utah, the reactor generated what Bloomberg described as a trickle of electricity to run an Nvidia AI computer and temporarily host a website. That result answers the narrow question of whether the system can produce any electrical current, but it does not yet prove sustained or commercially useful generation. The technical gap is now duration, output and integration. The next challenge is not another label for the same experiment. Valar must demonstrate that a reactor and its associated heat-conversion equipment can operate for meaningful periods at a defined output, respond safely to changing conditions and produce usable electricity with repeatable performance. Public reporting on the July demonstration does not provide a sustained electrical-output figure, operating duration, capacity factor or independently validated cost of generation. Those omissions do not invalidate the demonstration; they define its limits. Powering one computer is a visible proof of conversion from fission heat to electricity. Supplying an AI facility requires a complete generating system, including thermal management, electrical equipment, controls, maintenance procedures and an arrangement for delivering dependable power to the customer. The $6 billion bet extends beyond reactor physics. Valar's business thesis depends on manufacturing economics: standardized reactors produced repeatedly rather than one-off plants assembled through bespoke megaprojects. Investors are therefore funding execution across several linked problems - reactor performance, fuel supply, factory production, site preparation, safety authorization, financing and long-term operation. A successful prototype cannot establish the cost or schedule of a fleet. Valar still needs evidence that later units can be built consistently, that qualified components and fuel will be available in volume, and that operating data from Ward 250 can be translated into designs suitable for customers. Each step introduces constraints that a short electricity demonstration was not designed to resolve. Regulatory status is another boundary. Ward 250 operated through the Energy Department's pilot framework at a federal demonstration site; that does not automatically authorize commercial reactors at customer locations. Future projects will require the applicable federal, state and local approvals, as well as site-specific decisions about construction and operation. What the financing changes - and what it does not. The new capital gives Valar substantially more room to address these engineering and deployment tasks. It also raises the standard by which progress will be judged: after a $1 billion equity round at a reported $6 billion valuation, the relevant evidence is no longer criticality alone or a momentary electrical load. As of the August 4 financing disclosure, Ward 250 has sustained a controlled chain reaction and produced a small amount of electricity. What remains unproven publicly is dependable power at a meaningful output, followed by repeatable construction and commercial operation. The financing buys Valar time and capacity to pursue that transition; it does not demonstrate that the transition has already occurred.
