First major quantum IPO — $1.68B on Nasdaq
Reached
Quantinuum — Quantinuum priced an upsized IPO at $60/share, raising $1.68B on Nasdaq (QNT) at a ~$15.7B market value — the quantum industry's first mega-IPO. Honeywell retains ~48% voting power.
Milestone note Jun 2026
First new advanced-reactor design reaches criticality
Reached
Antares / Idaho National Lab — Antares' Mark 0 test reactor at Idaho National Laboratory achieved first criticality — a self-sustaining nuclear reaction and the first new US advanced-reactor design to cross the threshold (it is not yet generating power).

SpaceX IPO — biggest listing in history
Reached
SpaceX — SpaceX raised $75B in its IPO (555.6M shares at $135; ~$1.75T valuation), trading on Nasdaq as SPCX from 12 Jun 2026 — the largest IPO in history, dwarfing Saudi Aramco's $29.4B (2019); the book ran >2× oversubscribed (~$150B in orders).
SpaceX Milestone note Jun 2026
Axiom closes oversubscribed $525M round
Reached
Axiom Space — Axiom closed $525M+ (Feb $350M led by Type One Ventures & QIA, plus a $175M June extension joined by MUFG) to accelerate Axiom Station, spacesuits and human spaceflight — the largest station-sector raise amid NASA's CLD strategy rework.
Axiom Space Milestone note Jun 2026
Tiered safety deployment of a frontier model (Fable 5 / Mythos 5)
Reached
Anthropic — Anthropic released Claude Fable 5 — a Mythos-class model exceeding any it had made generally available — gated so ~5% of sensitive (e.g. cyber) sessions get a conservatively-tuned model, while the unrestricted Mythos 5 went only to vetted cyberdefenders via Project Glasswing with the US government. Days later the US Commerce Department export-controlled both models, barring all foreign-national access; unable to enforce that selectively in real time, Anthropic shut Fable 5 and Mythos 5 off worldwide (its other models unaffected) — the first time a deployed frontier AI model was export-controlled like a strategic technology.

Is BCI funding ahead of the medicine?
A $9B valuation for Neuralink prices in a future where brain implants are routine — but today's devices help a few dozen people in trials. Our read on the gap between capital and clinical reality. (Our opinion, not investment advice.)
Our read — labelled opinion, not investment advice.

Why "humans implanted" is the honest scoreboard
Demos and valuations are easy to inflate; people living with an implant are not. The count of humans implanted is the hardest signal that a BCI has crossed from lab to clinic — and Synchron, not the loudest name, leads it.

Waymo pauses all freeway robotaxi rides
Reached
Waymo — Waymo suspended all freeway rides (San Francisco, LA, Phoenix, Miami) to improve construction-zone handling, after recalling 3,791 vehicles over flooded-roadway incidents — a notable safety pullback on its hardest driving domain.
Waymo Milestone note May 2026
New Glenn destroyed in static-fire explosion
Reached
Blue Origin — A New Glenn first stage exploded during a static-fire test at LC-36, Cape Canaveral (28 May 2026) — destroying the booster and damaging Blue Origin's only New Glenn pad. Reported as the most powerful rocket explosion since the Soviet N1 (1969); no injuries. Blue Origin targets return to flight before end-2026, accelerating a vertical-integration redesign.
Blue Origin Milestone note May 2026
Starship V3 — debut flight of the most powerful rocket
Reached
SpaceX — SpaceX flew Starship V3 for the first time (Flight 12, 22 May 2026) — its most powerful version, built for high-rate Starlink launches and future Moon missions. The suborbital test deployed 20 mock + 2 real Starlinks and was called a success despite engine glitches and a missed booster splashdown; full orbital flight is still to come.

Recovered vs reused: what reusability really means
Landing a booster is the photo; flying the same booster again — and again — is the economics. We explain why reflights, not landings, are the metric that lowers the cost of space.

Piloted vs autonomous, long vs short hop
Air-taxi makers are not building the same vehicle. Joby and Archer bet on piloted, ~100-mile aircraft; EHang and Volocopter fly shorter, often autonomous hops. The range spec reveals the strategy.
Explainer Apr 10, 2026
Why we don't score "AGI"
There is no agreed test for general intelligence, so a single "AGI %" would be our opinion dressed as data. Instead we track objective, third-party numbers: training compute, public benchmark scores, and investment.
Explainer Apr 8, 2026
The 5 stages of air-taxi certification
An eVTOL can fly thousands of test flights and still not be allowed to carry a paying passenger. The gate is FAA type certification — a five-stage process — and it, not flashy demos, is the real finish line.
EHang Milestone note Apr 3, 2026
US FY2027 budget request for fusion lands below authorized levels
The White House's FY27 request for Fusion Energy Sciences is $755M — $50M below FY26 and well short of the $1.11B authorized by the CHIPS and Science Act — even as public-private partnership funding rises to $135M and a new Office of Fusion is proposed. A contrast with Europe, where Germany just joined a multi-billion-euro fusion IPCEI.

ARPA-E's largest-ever fusion investment ($135M)
Reached
ARPA-E (US DOE) — ARPA-E committed $135M to fusion over 18 months — more than its entire prior 12 years of fusion funding combined — launching CHADWICK (first-wall materials for a 40-year plant life) and GAMOW (market-aligned fusion) programs.
Milestone note Apr 2026
First Light — £25m first close + first amplifier sales
Reached
First Light Fusion — First Light closed a £25m first tranche (Starmaker One + UKAEA) and shipped its first VIPER III velocity amplifiers to Texas A&M — a pivot to selling its amplification tech while pursuing its FLARE inertial-fusion concept (target gain ~1,000).
First Light Fusion Milestone note Apr 2026
2:1 physical-to-logical qubit ratio (with Harvard/MIT)
Reached
QuEra / Harvard / MIT — QuEra, Harvard and MIT showed qLDPC codes encoding 1,156 logical qubits into 2,304 physical (≈2:1, >50% rate), simulated into the "teraquop" regime (~1 error per trillion ops) — versus the hundreds-to-one ratio typical today.
QuEra Milestone note Apr 2026
First power-producing Gen IV reactor breaks ground
Reached
Kairos Power — Kairos broke ground on Hermes 2 in Oak Ridge — the first power-producing Gen IV reactor with an NRC construction permit. The molten-salt-cooled plant will feed up to 50 MW to TVA, powering Google data centers.
Kairos Power Milestone note Apr 2026
China freezes new robotaxi permits after Baidu outage
Reached
China (MIIT) / Baidu — After 100+ Baidu Apollo Go robotaxis failed simultaneously in Wuhan (a cloud outage stranded riders up to two hours), China suspended all new autonomous-driving permits on 29 Apr 2026 — the first nationwide robotaxi licensing freeze.

First frontier model shipped on domestic Chinese silicon
Reached
DeepSeek / Huawei — DeepSeek's 1.6T-parameter V4 runs on Huawei Ascend (950PR), and a Huawei-led team completed full-parameter post-training on ~1,000 Ascend 910Cs — a compute-sovereignty landmark. Pre-training hardware remains undisclosed, so "trained without Nvidia" is NOT established.

Robotaxi vs driver-assist: the SAE levels
“Self-driving” spans everything from lane-keeping (Level 2) to no-human-needed robotaxis (Level 4). Waymo runs Level 4 in set areas; most consumer “autopilot” is Level 2. The gap is the whole game.

The nines: why gate fidelity matters
99.9% vs 99.99% looks like a rounding error but means 10× fewer mistakes. Error correction only pays off above a threshold near “three nines”; crossing “four nines” buys real headroom.

Scientific vs engineering breakeven
NIF passed scientific breakeven in 2022 — but the lasers drew ~300 MJ from the wall to deliver 2 MJ to the target. Engineering breakeven, where the whole plant nets energy, is the bar that matters for the grid.

Physical vs logical qubits — don't confuse them
A 6,100-qubit array and 96 logical qubits sound contradictory until you know the difference. Physical qubits are the raw, noisy hardware; logical qubits are many physical ones error-corrected into one reliable unit. The second number is the one that matters.
