Fusion — the reaction that powers the Sun — has lived inside government labs in India for decades. In 2026 that changed: a 12-person Bengaluru startup, Pranos Fusion, built PRAGYA, India’s first privately-made nuclear fusion tokamak, and raised $6.8 million to chase a full reactor by 2030. Here’s what it is, why it matters, and where India now sits in the global fusion race.
What is a tokamak — and what is PRAGYA?
A tokamak is a doughnut-shaped chamber that uses powerful magnetic fields to trap superheated plasma — the electrically charged fourth state of matter — long enough for atomic nuclei to fuse and release energy. PRAGYA (Sanskrit for “first knowledge”) is a compact, low-aspect-ratio tokamak. But here’s the crucial part: it isn’t built to produce fusion. It’s a testbed — it creates and confines plasma to prove out the control systems and engineering, without reaching the temperature where nuclei actually fuse.
Why PRAGYA is a rehearsal, not the reactor
Real fusion needs roughly 100–150 million °C — hotter than the Sun’s core. PRAGYA deliberately stops short: it validates the machine before Pranos attempts a reactor that goes all the way.
Three pieces, all built in-house
Unlike a single-product startup, Pranos is building three interlocking layers of the fusion puzzle at once:
The hardware
The physical tokamak testbed — creates and confines plasma to validate the engineering.
The software
Design-and-control software baked in from day one. Expected to hit commercial pilot first — targeted for next year.
The magnets
In-house high-temperature superconducting (HTS) magnets — the key to smaller, compact reactor designs.
The money: from ₹20 lakh to $6.8 million
Pranos Fusion — funding journey
The March 2026 round was co-led by pi Ventures and Ankur Capital, with backers including Groww co-founder Lalit Keshre and Razorpay’s founders. Total raised: a little over $7 million — going into HTS magnet R&D, commissioning the tokamak, and growing the team.
Where India sits in the global fusion race
India’s fusion work has run almost entirely through government institutions — chiefly the Institute for Plasma Research (IPR) in Gandhinagar, home to the Aditya-U and SST-1 tokamaks. Pranos is the first private entrant to build a working tokamak here, alongside another Indian startup, Anubal.
Why this matters if you’re a student or researcher
For anyone in plasma physics, computational fluid dynamics, materials science or aerospace engineering, Pranos is genuinely new: a private-sector fusion employer in India, sitting beside the traditional IPR/BARC government path. It’s also a signal that Indian deep-tech investors will now fund multi-year, capital-heavy hard-science bets — not just apps. If you’re drawn to frontier science, the door just opened a little wider.
FAQ
Can PRAGYA actually produce fusion?
No — it’s a testbed for plasma control and confinement. Real fusion is the job of Praniq, the full reactor Pranos plans next.
How much has Pranos raised in total?
A little over $7 million (~₹63+ crore) — a government seed grant, an early ₹3.5 crore round, and the $6.8 million round in March 2026.
Has anyone achieved commercial fusion energy yet?
No. No company or government project — including ITER, Helion, or Commonwealth Fusion Systems — has yet demonstrated continuous, net-positive commercial electricity from fusion.
