Three Countries Now Mine Three-Quarters of the World's Uranium

Three Countries Now Mine Three-Quarters of the World's Uranium New 2026 production data confirm Kazakhstan, Canada and Namibia dominate mine supply just as nuclear demand forecasts climb, leaving buyers exposed to a thin roster of sources. Around three-quarters of the world's mined uranium now comes from just three countries, and the top five producers account for close to 90% of global mine output in the latest data, according to a ranking published by ceoworld.biz on Friday (2026-06-13).⁶ For utilities and traders sourcing nuclear fuel, that concentration sets the boundary of the market. Global mine production runs at roughly 50,000 to 55,000 tonnes of uranium a year, broadly matched to reactor demand, with the balance filled by secondary supply such as stockpiles and re-enriched tails.⁶ Kazakhstan, Canada and Namibia together supply nearly three-quarters of mine output.⁶ Add Australia and Uzbekistan and the top five approach 90% of global supply.⁶ Kazakhstan alone consistently delivers around 40% to 45% of mined uranium, a share that gives its state producer leverage over the fuel chain that few commodity suppliers of comparable scale enjoy.⁶ That single-country weight sits against demand forecast to rise sharply. The World Nuclear Association expects uranium demand to climb about 28% by 2030 and more than double by 2040.³ The United States alone wants to quadruple nuclear capacity, from roughly 100 gigawatts in 2024 to 400 gigawatts by 2050.³ If those targets hold, the call on a narrow producer base grows year by year.³ Markets have already begun to price the squeeze. The Global X Uranium ETF stood at $45.52, up 1.16% in its latest session.⁶ Citi analysts have forecast spot uranium rising as high as $125 per pound this year as nuclear interest pulls demand past supply.² That is a forecast, not a settled price, and one bank's call should be weighed against the secondary supply that has capped earlier rallies.² Canada is where the supply response is clearest. The Canadian Nuclear Safety Commission has granted federal approval to two new uranium mines in Saskatchewan, the first since Cameco's Cigar Lake, according to a report on ca.news.yahoo.com dated 2026-05-28.⁵ Analysts cited in that report argue shifting geopolitical conditions will strengthen Saskatchewan's position further.⁵ Cameco anchors that position. Its Cigar Lake operation produces the world's highest-grade uranium and has yielded more than 155 million pounds since starting up in 2015, while its McArthur River complex has produced 567.9 million pounds over its life, the Motley Fool reported on 2026-05-21.¹ In 2024 the company mined about 17% of global uranium, second only to Kazakhstan's Kazatomprom at 21%.³ The gap to the rest of the field is wide. Orano, the next closest producer, accounted for roughly 11%, leaving Cameco and Kazatomprom as the two names that set the tone for Western buyers.³ Cameco also holds a 49% stake in Westinghouse, which is designing a small modular reactor, tying the producer to demand as well as supply.³ Analysts expect that to feed earnings. From 2025 to 2028, Cameco's revenue and adjusted EBITDA are forecast to grow at compound annual rates of 8% and 12% respectively, the Motley Fool reported.² Those numbers assume the demand curve holds and new Saskatchewan tonnes arrive on schedule.² The geopolitics sharpen the case for diversification. The Economist, writing on 2026-05-19, described the Kremlin's dominance of the cross-border trade in nuclear fuel and enrichment technology as a chokehold on the world.⁴ Mine output is only one link; enrichment and conversion remain heavily concentrated in Russia, which is why Western utilities have pushed to rebuild supply closer to home.⁴ What is harder to see is whether the new mines close the gap or merely keep pace with demand. Two Saskatchewan approvals do not offset Kazakhstan's 40%-plus share, and the secondary supply that has plugged the deficit for years is finite.⁶ The next markers are whether spot uranium tests Citi's $125 forecast and whether the Saskatchewan projects move from approval to first production on the timeline their backers promise.^2,5
