Oklo $OKLO: Compact Reactors Aim to Meet AI Data Centre Demand by 2028

The surge in artificial intelligence (AI) applications has created an unprecedented demand for energy, particularly for data centres that underpin these technologies. Amidst this backdrop, Oklo Inc, a company developing compact nuclear reactors, emerges as a potential solution to a pressing problem. Unlike traditional nuclear plants that require decades to build, Oklo’s innovative approach promises rapid deployment and the use of recycled fuel, positioning it as a contender to meet the urgent power needs of tech-driven industries. This analysis explores the viability of Oklo’s technology, its deployment timeline, and its relevance to the data centre energy crisis as of mid-2025.

The Energy Challenge of AI Data Centres

Data centres, especially those supporting AI workloads, are voracious consumers of electricity. Industry estimates suggest that global data centre power consumption could reach 1,000 terawatt-hours annually by 2030, driven largely by AI training and inference tasks. In 2025, reports indicate that major tech firms are already grappling with power supply constraints, with some delaying new facilities due to grid limitations. Oklo’s proposition of small, modular nuclear reactors offers a theoretical fix: clean, high-density energy that can be deployed closer to demand centres, bypassing the bottlenecks of traditional grid infrastructure.

Oklo’s Technology and Deployment Edge

Oklo’s flagship product, the Aurora reactor, is a liquid metal-cooled fast reactor designed to generate up to 75 megawatts (MW) of power, a capacity increase from the 50 MW initially planned for 2025. This scalability reflects the company’s response to accelerating demand from large customers, particularly in the data centre sector. The reactors are engineered for off-grid applications, making them suitable for remote or high-demand locations such as industrial sites or tech hubs. A key differentiator is the use of recycled nuclear fuel, which not only addresses waste concerns but also reduces dependency on fresh uranium supplies.

Deployment speed is another critical factor. While conventional nuclear plants often take 10 to 20 years from planning to operation, Oklo targets a timeline of mere months for site preparation and installation once regulatory hurdles are cleared. As of Q2 2025 (April to June), the company has made strides with an Interface Agreement signed with Idaho National Laboratory (INL), aiming for commercial operations of its Aurora-INL reactor by late 2027 or early 2028. Pre-construction activities are slated to begin later in 2025, marking a significant step towards realising this ambitious timeline.

Market Positioning and Customer Pipeline

Oklo’s order book underscores growing interest in small modular reactors (SMRs). As of mid-2025, the company has secured Letters of Intent to supply approximately 2,100 MW of nuclear power, including 750 MW specifically earmarked for two data centre operators. This pipeline reflects a broader trend: tech companies are increasingly exploring nuclear options to secure stable, carbon-neutral energy sources. For context, a single hyperscale data centre can require 100 to 300 MW of power, meaning Oklo’s commitments could support several large-scale facilities if executed as planned.

The following table outlines Oklo’s current customer commitments as reported in Q2 2025:

Regulatory and Operational Risks

Despite the promise, significant challenges remain. Nuclear energy, even on a small scale, faces stringent regulatory oversight. While Oklo has made progress with siting agreements, full licensing and safety approvals are pending as of Q2 2025. Any delays could push deployment beyond the 2027 target, a risk not uncommon in the nuclear sector. Moreover, while the concept of rapid deployment sounds appealing, real-world execution—especially in supply chain logistics and site-specific adaptations—could temper the pace.

Financially, Oklo’s path to profitability is untested. Building and deploying reactors require substantial capital expenditure, and the company must balance this against revenue generation timelines. Investors, while optimistic as seen in various online discussions including posts on platforms like X under handles such as Mindset for Money, CPA, should remain cautious of overblown expectations in a field where delays are historically commonplace.

Broader Implications for the Energy Sector

Oklo’s potential extends beyond data centres. Its technology could serve remote communities, military bases, and industrial sites, diversifying its market reach. Additionally, the ability to produce radioisotopes through fuel recycling opens ancillary revenue streams in medical and industrial applications. If successful, Oklo could redefine perceptions of nuclear power as not just a large-scale, centralised solution but a nimble, localised one.

However, competition in the SMR space is heating up. Other firms are also racing to deploy compact reactors, and Oklo must maintain its first-mover advantage. The broader energy transition context adds another layer: while nuclear offers carbon-free power, it must compete with rapidly advancing renewables like solar and wind, which benefit from shorter deployment times and lower regulatory barriers.

In conclusion, Oklo Inc stands at a pivotal juncture in 2025. Its compact nuclear reactors address a genuine and escalating need for reliable, high-density power in the AI-driven data centre boom. The technology and deployment strategy show promise, but execution risks and regulatory timelines will be decisive. For now, Oklo represents a calculated bet on the future of energy—one that could pay off handsomely if the stars align, or fizzle out if the complexities of nuclear innovation prove too cumbersome. The next two years will be telling.
