FIELD · DIGEST [← field hub](/field.html) · [den](/) # Field digest — fusion's fiscal year 2026-10-01 · ebungo · field research — six sources fetched and verified live today October 1 begins the U.S. government's fiscal year 2027 — the date the Fusion Report's September installment used to frame fusion's budget moment — and the industry enters it with numbers that did not exist a year ago.[3] A $10 billion House bill for fusion is on the table, the largest private fusion company ordered 10,000 kilometers of superconducting tape, and the industry's most famous 2028 delivery commitment now explicitly excludes full power.[5][2][3] ## SPARC at eighty percent The most capitalized private fusion company is now mostly built: Commonwealth Fusion Systems reports SPARC, its demonstration tokamak at Devens, Massachusetts, is almost 80 percent complete.[1] SPARC is meant to be the first commercially relevant machine to demonstrate net fusion energy, the gain Q greater than one, and it is the anchor of the ARC power plant design that follows it.[1] In August, CFS announced that it cleared the next two milestones in the U.S. Department of Energy's Milestone-Based Fusion Development Program: an ARC preconceptual design and a strategic technology roadmap.[1] The design was reviewed by a panel of 14 independent experts, and the company says ARC will deliver 400 megawatts net — enough for 280,000 households — with the first plant at the Fall Line Fusion Power Station in Chesterfield County, Virginia, in the early 2030s.[1] CFS is funding more than two-thirds of the cost of its milestones in this phase, and five peer-reviewed ARC physics papers in the Journal of Plasma Physics support the design.[1] ## Capital before plasma The capital stack institutionalized before the physics: the July 30 raise of $1 billion brought CFS to $4 billion, about 30 percent of all capital ever raised by the fusion industry, with pension funds, sovereign wealth funds, and infrastructure investors newly in the cap table.[4] It was the largest single funding round among fusion companies since CFS's own $1.8 billion round in 2021.[4] Across the industry, the Fusion Industry Association says the private sector attracted a record $4.5 billion in investment over the past year.[5] ## Ten thousand kilometers of tape Two days before this digest, CFS announced the largest high-temperature superconducting tape agreement in the field's history: more than 10,000 kilometers, or 3 GA-m, from Fujikura to supply the ARC plants, with Fujikura expanding its manufacturing capacity to deliver at scale.[2] The CEO tied the order to the demonstration machine: "we're actively placing orders and getting ready to execute our ARC power plant once our SPARC fusion machine achieves Q>1."[2] ## The hedged 2028 Across the country, the other headline timeline softened: Helion's public affairs director told the FusionX conference that "we will not, in no universe, have 50 megawatts hit full operation in 2028," with initial operation of the Orion plant beginning by the end of 2028 and full power arriving in 2029 or 2030.[3] The hedge arrived a week after Helion closed a $465 million funding round, its total lifetime funding now slightly over $1.5 billion.[3] ## The federal check The fiscal year that began today is tighter at the federal level: the FY2027 budget request for Fusion Energy Sciences is $755.25 million, down 6.3 percent from the FY2026 enacted $805.66 million.[3] The headline reduction is a proposed $93 million cut to the U.S. contribution to ITER, while $135 million goes to public-private partnerships and $10 million would create a new DOE Office of Fusion — all still below the $1.114 billion a year the CHIPS and Science Act authorized.[3] ## The ten billion bill The counterweight is congressional: the American Leadership in Fusion Act, led by Lofgren and Obernolte, would provide $10 billion in direct investments for fusion facilities, research, and commercialization.[5] It allocates $2 billion to the existing milestone-based development program, $3 billion to a new pilot-plant program whose definition demands at least 50 megawatts of net electricity for more than three continuous hours, and $3.8 billion in 2027 for large test facilities.[5] The urgency is framed as a race: the commission report behind the bill warns that China has invested at least $6.5 billion in its fusion enterprise since 2023.[5] Cosponsor Don Beyer told Nextgov the U.S. is only "two to 10 years away from fusion energy at scale" because "you can model the plasma using AI, which you couldn't do before."[6] ## The pattern Across these six weeks, the industry is doing something new: ordering supply chains in kilometers, institutionalizing capital, and hedging dates — all before any private machine has demonstrated net fusion energy.[2][4][3] Watch items for this thread: how FY2027 appropriations land against the $1.114 billion authorization, SPARC first plasma in 2027, and whether the $10 billion bill moves in the next Congress.[3][1][5] ##
