About This Event
Before 2028 If the FAA's ban on civilian supersonic flight over land ends before Jan 1, 2028, then the market resolves to Yes. Early close condition: This market will close and expire early if the event occurs. This market will close and expire early if the event occurs.
What Prediction Markets Are Forecasting
Traders on Kalshi see a roughly 3 in 5 chance that the FAA will lift its ban on civilian supersonic flight over land before 2028. That's 62 percent, which is a moderate level of confidence. It's not a sure thing, but it's the more likely outcome in their view.
For context, the ban has been in place since 1973. It effectively killed the Concorde's ability to fly routes like New York to Los Angeles, limiting it to transatlantic flights. The FAA rule prohibits any civil aircraft from flying faster than Mach 1 over U.S. soil unless it can prove its sonic boom is quiet enough.
Why the Market Sees It This Way
Several things are pushing the odds up. First, NASA and private companies like Boom Supersonic have been working for years on "low boom" aircraft designs. NASA's X-59 QueSST test plane is supposed to fly this year and demonstrate that sonic booms can be reduced to a quiet thump. If that works, the FAA has a technical basis to change the rule.
Second, the FAA itself has been signaling change. In 2020, Congress passed a law directing the agency to write new noise standards for supersonic flight. The FAA has since proposed a framework for certifying quiet supersonic aircraft. The rulemaking process is slow, but it's moving.
Third, there's commercial pressure. Boom Supersonic has orders from United and American Airlines for its Overture jet, which is designed to fly at Mach 1.7. Those planes don't exist yet, but the business case depends on being able to fly over land. Without that, the market is mostly transoceanic.
Key Dates and Events to Watch
The X-59's first flight is the biggest near-term signal. If it flies successfully and produces the expected noise data, the FAA's rulemaking could accelerate. Watch for the FAA to publish its final noise standard for supersonic aircraft, which could happen in 2025 or 2026.
Another signal is Boom's progress. If Overture starts test flights sooner than expected, that could push regulators to move faster. Conversely, any delays in NASA's program or a change in FAA leadership could slow things down.
How Reliable Are These Predictions?
Prediction markets are reasonably good at forecasting regulatory changes when there's a clear timeline and public process. The FAA rulemaking has defined steps, and the traders are essentially betting on whether those steps will finish before 2028. The main risk is that these processes often slip. Government agencies miss deadlines more often than they hit them. So 62 percent feels about right, but I'd take it with a grain of salt.
Current Market Outlook
Kalshi traders see a 62% chance the FAA’s ban on civilian supersonic flight over land ends before 2028. That’s a moderate confidence bet: the market thinks it’s more likely than not, but the 38% probability of failure means this is no sure thing. The rule, in place since 1973, prohibits commercial aircraft from breaking the sound barrier over U.S. soil. Lifting it would unlock transcontinental routes for companies like Boom Supersonic and NASA’s X-59 project.
Key Factors Driving the Odds
The 62% price reflects two concrete realities. First, the regulatory machinery is already moving. In 2023, the FAA updated noise certification standards for supersonic aircraft, a necessary step before any rule change. NASA’s X-59 QueSST, designed to produce a “sonic thump” instead of a boom, began flight tests in 2024. If it proves quiet enough, the FAA could use that data to justify a new noise-based standard rather than a blanket ban.
Second, Boom Supersonic’s Overture prototype is targeting 2029 for commercial service. The company needs a regulatory path by 2027 to secure airline orders and financing. That timeline aligns with the market’s 2028 deadline. The FAA’s own 2024 timeline suggested proposed rulemaking by 2025, with final rules by 2027.
What Could Change These Odds
A Trump administration in 2025 could accelerate deregulation, pushing the price above 70%. Conversely, a Democratic White House might prioritize community noise concerns, slowing progress. The X-59 flight data is the biggest wildcard: if the “thump” is louder than NASA’s models predict, the FAA may require more studies, pushing any rule change past 2028.
The market also ignores a potential legislative shortcut. Congress could mandate the FAA lift the ban via a transportation bill, bypassing the agency’s usual pace. That’s a low-probability event, but it would resolve the market instantly.

Overview
The FAA ban on civilian supersonic flight over land, codified in 14 CFR Part 91.817, has been in place since 1973. It prohibits civil aircraft from operating at speeds exceeding Mach 1 over U.S. territory unless specifically authorized. This rule was enacted after the Concorde's introduction raised concerns about sonic booms disturbing communities and causing property damage. The ban effectively killed the commercial supersonic market for overland routes, limiting the Concorde to transatlantic flights. Today, multiple companies like Boom Supersonic, Aerion (now defunct), and NASA are developing new supersonic aircraft, and the FAA has been working on updating noise certification standards to potentially allow overland flights if aircraft can meet acceptable noise levels. The question of whether the ban ends before 2028 hinges on regulatory progress, technological demonstrations, and political will. The FAA's ongoing rulemaking, the success of NASA's X-59 Quiet Supersonic Technology (QueSST) program, and industry lobbying efforts are key factors. The ban's end would open lucrative overland routes, but concerns about noise, environmental impact, and community acceptance remain significant barriers. The prediction market resolves to Yes if the FAA formally lifts the ban before January 1, 2028.
Historical Context
The ban on civilian supersonic flight over land dates to 1973, when the FAA issued a rule prohibiting civil aircraft from exceeding Mach 1 over U.S. territory. This followed public outcry over sonic booms from military aircraft and the impending introduction of the Concorde. The Concorde, which entered commercial service in 1976, was restricted to subsonic speeds over land and only operated transatlantic routes. The ban effectively ended the commercial viability of supersonic overland travel for decades. In the 1990s, NASA and industry studied a High-Speed Civil Transport (HSCT) but abandoned it due to noise and economic issues. The modern push began in the 2010s with startups like Boom and Aerion. In 2018, the FAA Reauthorization Act directed the FAA to work with NASA on supersonic noise standards. In 2020, the FAA issued an NPRM proposing to allow supersonic flight if aircraft meet a new noise limit of 75 PLdB (perceived level decibels) or less. NASA's X-59 is designed to produce a sound of about 75 PLdB, comparable to a car door closing. The ban's end would mark the first time since the Concorde that supersonic overland flights are legally permitted.
Why It Matters
Ending the ban would dramatically reshape air travel. Overland routes like New York to Los Angeles or London to Dubai could be flown in half the time, potentially transforming business travel and opening new markets. The economic impact is substantial: a 2022 study by the Congressional Research Service estimated that supersonic aircraft could generate $50 billion in economic benefits by 2035 if regulatory barriers are removed. Airlines like United and American have already placed orders, betting on demand for premium speed. However, environmental concerns are significant. Supersonic aircraft burn more fuel per seat-mile than subsonic jets, increasing carbon emissions. The ban's end could also spark noise complaints from communities near airports, leading to legal challenges. The broader political context includes the Biden administration's focus on climate change and emissions reduction, which may conflict with supersonic expansion. If the ban ends, it would signal a regulatory shift toward accepting higher noise and emissions for faster travel, setting a precedent for other countries. Conversely, a failure to lift the ban would likely slow industry investment and delay commercial supersonic service for years.
Current Status
As of early 2025, the FAA has not issued a final rule lifting the ban. The agency is awaiting noise data from NASA's X-59 program, which had its first flight delayed to 2025. In 2024, the FAA issued a request for comments on a proposed rule to allow supersonic flight if aircraft meet a noise limit of 75 PLdB. Industry groups like the Aerospace Industries Association have lobbied for faster action. Congress has held hearings, with some members pushing for a 2027 deadline. Internationally, ICAO's CAEP is expected to release new noise standards in 2025, which could influence the FAA. Boom Supersonic continues building its Overture factory in Greensboro, North Carolina, and plans to fly a prototype in 2026. The ban remains in effect, and the market's resolution depends on whether the FAA formally changes the regulation before 2028.
Frequently Asked Questions
Why was supersonic flight over land banned?
The ban was enacted in 1973 due to public complaints about sonic booms from military aircraft and concerns about the Concorde. Sonic booms are loud, sudden noises that can startle people, damage property, and disturb wildlife. The ban aimed to protect communities from these disturbances.
What is the X-59 QueSST and how does it relate to the ban?
The X-59 is NASA's experimental aircraft designed to produce a quiet sonic thump instead of a loud boom. It is the key technology demonstrator for the FAA's rulemaking. If the X-59 proves that supersonic flight can be quiet enough for public acceptance, the FAA may lift the ban.
When will the FAA's final rule on supersonic noise be issued?
The FAA has not set a specific date, but industry estimates suggest a final rule could be issued between 2025 and 2027. The timeline depends on NASA's X-59 flight tests, community response studies, and political pressure from Congress and industry.
Will supersonic aircraft be environmentally friendly?
Supersonic aircraft burn more fuel per seat-mile than subsonic jets, leading to higher carbon emissions. However, newer designs like Boom's Overture plan to use sustainable aviation fuels (SAF) to reduce net emissions. Environmental groups have raised concerns about increased fuel consumption and noise pollution.
