Boom Supersonic, Inc.
Startup building a supersonic airliner and now gas turbines for data centers.
Boom has flown supersonic and booked billions in orders and turbine backlog, but the airliner itself is still unbuilt and uncertified eleven years in.
Boom Supersonic is working to build the first passenger plane that flies faster than the speed of sound since the Concorde retired in 2003. The company has proven it can make the physics work (they flew a test plane and showed how to cruise quietly over land), but they have not sold a single ticket or delivered an airplane yet, and they won't be allowed to fly passengers until around 2029 at the earliest if everything goes right. Big aircraft makers like Boeing and Airbus could build a supersonic plane if they wanted to, and companies like GE and Siemens that make engines have way more experience and money than Boom does. The one thing that matters most right now is whether Boom can successfully test its custom Symphony engine in the next couple of years; if that engine fails or gets delayed, the whole company probably falls apart because the entire plan depends on it working.
Symphony engine reaches full-scale core test without major slippage. Shows whether Overture's engine risk is being retired on schedule.
Superpower delivers its first turbines to Crusoe around late 2027. Shows whether Boom's turbine sideline can generate real revenue on time.
- $1.5B post-money valuation after $300M round
- Superpower turbine backlog over $1.25B
- XB-1 hit Mach 1.122, first private civil supersonic flight
- FAA final overland supersonic rule (due June 6, 2027) lands unfavorable or delayed.
- Symphony engine hits major technical wall in full-scale core testing.
- Capital gap versus $15-30B typical clean-sheet airliner certification cost against ~$1B raised.
- Superpower first turbine deliveries slip past late 2027 target.
- Narrative/investor attention shifts to Hermeus after its Mach 1.21 flight and $1B valuation.
| Rival | Direction | Evidence |
|---|---|---|
| Hermeus | contesting | Flew Quarterhorse Mk 2.1 at Mach 1.21 in May 2026, raised $350M at $1B valuation Apr 2026 |
| Boeing/Airbus | contesting | Overture aims to cannibalize long-haul first-class travel but incumbents stayed out of supersonic by choice, not barrier |
| GE Vernova, Siemens Energy, Mitsubishi Power | losing to | Unblocked turbine incumbents with scale and delivery track record vs Boom's pre-delivery Superpower unit (late 2027 target) |
| Aerion Supersonic | gaining on | Former supersonic-jet rival went defunct in 2021, removing one competitor from the field |
- Is Boom Supersonic profitable in 2026?
- No. Boom's core Overture airliner remains pre-revenue after 11 years, with certification targeted for the end of the decade. Its new Superpower turbine unit has a $1.25B+ backlog (Dec 9, 2025) but first deliveries are not expected until late 2027, so no product revenue has been recognized yet.
- Could AI replace Boom Supersonic's engineers?
- Unlikely. Boom's value sits in physical flight testing, FAA/EASA certification, and manufacturing (XB-1 flew supersonic Jan 28, 2025, Mach 1.122), none of which AI can substitute. AI is instead a demand driver for Boom's new turbine business, not a replacement threat to its core work.
- Who owns Boom Supersonic?
- Boom Supersonic (legal name Boom Technology, Inc.) is privately held and venture-backed, founded by CEO Blake Scholl in Denver on September 26, 2014. Its Dec 9, 2025 $300M round was led by Darsana Capital Partners with Altimeter, ARK Invest, Bessemer, Robinhood Ventures and Y Combinator, valuing it at $1.5 billion.
- Who is Boom Supersonic's biggest competitor?
- In supersonic flight, Hermeus is the closest peer, flying its Quarterhorse Mk 2.1 at Mach 1.21 in May 2026 and raising $350M at a $1B valuation in April 2026. In Boom's new turbine business, established players like GE Vernova, Siemens Energy, and Mitsubishi Power are unblocked incumbents with far greater delivery track records.
- Has Boom Supersonic's Overture airliner actually flown?
- Not yet. The Overture airliner itself has not flown; Boom's XB-1 demonstrator broke the sound barrier on January 28, 2025 (Mach 1.122) and completed a 2026 flight-test campaign showing 'boomless cruise' with no audible ground sonic boom, but this was a one-third-scale test vehicle, not the commercial jet.
- When will Boom Supersonic's Overture be certified?
- Boom targets certification by the end of this decade (around 2029), contingent on the FAA finalizing its supersonic overland noise rule by June 6, 2027. As of March 2026, aviation experts cited by local Greensboro reporting gave roughly 50/50 odds on Boom's stated timeline.
