Kalshi's proposed flight-cancellation contracts are encountering a significant hurdle due to a settlement data gap. The primary data source, FlightAware, has rejected the planned use, while the public backup from the Bureau of Transportation Statistics (BTS) is significantly delayed. This mismatch threatens the contracts' utility as a timely indicator of airline risk.
The contracts, designed to settle one week after each measurement period, rely on accurate and prompt data. However, FlightAware's parent company, RTX Corp (NYSE:RTX), has stated it did not authorize the planned use, warning that violators could lose access. Meanwhile, BTS's public on-time series currently only extends through May 2026, creating a lag of over six weeks as of the July 16 dateline.
For investors, the contracts aim to provide a normalized measure of airport stress, expressed as a percentage to compare airports of different sizes. The value of this signal, however, hinges on timely and trusted inputs. Without a resolution to the data issue, the contracts may serve more as an experimental stress signal than a reliable hedging tool.
Kalshi filed a self-certification with the Commodity Futures Trading Commission on July 14, outlining a source hierarchy with FlightAware as primary and BTS as backup. The settlement calculation uses cancellations divided by scheduled flights, truncated to two decimals. Notably, delays, diversions, and gate returns that later depart are excluded, making this a narrow cancellation gauge rather than a full disruption index.
The contracts could be most relevant at concentrated hubs like O'Hare, where United Airlines Holdings (NASDAQ:UAL) and American Airlines Group (NASDAQ:AAL) dominate. The FAA has maintained a 10% schedule cut at O'Hare through October 2027. Despite the data challenges, core earnings drivers for airlines remain mixed. United's third-quarter adjusted profit midpoint of $3 per share trailed the LSEG consensus of $3.60, and the company warned of nearly $6 billion in additional 2026 fuel costs.
However, United raised its full-year adjusted earnings range to $9-$11 per share, and CEO Scott Kirby stated, "United has never been in a stronger competitive position." Shares were down 2.5% at the latest quote. American's shares were 0.7% lower, while RTX was down 0.4%.
The key risks for the proposed market include potential restriction of FlightAware access, BTS reporting after contract expiry, and no trading history. Excluding delays and diversions also introduces basis risk for airline investors. Until the source issue is resolved, the contracts may function better as an experimental stress signal than a dependable hedge.
