The Artificial Sun

Fusion, the reaction that powers the sun, and the great dream of limitless clean energy, is a field where China now spends and builds harder than anyone. Its flagship, the EAST tokamak in Hefei, nicknamed the “artificial sun,” sustained a high-confinement plasma for 1,066 seconds in January 2025, shattering its own previous record of 403 seconds and holding superheated plasma stable for the kind of duration that continuous power would demand.^[1]

The commitment behind that number is serious. China is building a new burning-plasma machine, BEST, targeted for completion around 2027, and planning the larger CFETR beyond it.^[2] On money, one 2025 injection put roughly $2.1 billion into a new state fusion company, on the order of two-and-a-half times the entire annual US public fusion budget, and China leads the world in fusion patents.^[3][4] Even its private sector moves fast: the startup Energy Singularity built HH70, billed as the first tokamak with high-temperature superconducting magnets, in about two years.

A thousand seconds of plasma is a genuine record. It is also not a single watt of electricity, and that distinction is the whole story.

The reality behind the record

Here the honesty has to be relentless, because fusion attracts hype like no other field. None of these machines produces net electricity; EAST’s 1,066 seconds is a plasma-confinement duration record, not energy gain.^[1] The record was itself beaten weeks later by France’s WEST tokamak, at 1,337 seconds — a reminder that this is incremental, international progress, not a Chinese finish line.^[1] And the budget comparisons mix one-off capital injections with annual research spending, so the “double the US” framing is directional, not exact.

The signal underneath

Fusion is the ultimate long-duration bet, and China is positioning to be the country that runs hardest at it, more money, more machines, more patents, and a private sector willing to move. That is strategically significant even though commercial fusion is, on the mainstream scientific view, unlikely before around 2050. For investors the discipline is to hold both truths at once: China’s fusion program is a genuine and widening lead in capability and investment, and it is decades from a power bill. We treat it as a national-capability signal and a source of spillover science, superconducting magnets, materials, plasma control, rather than an investable energy business this decade. The sun is hard to bottle; China is simply spending the most to try.
