This market resolves to the launch provider responsible for the last orbital launch attempt worldwide with a liftoff time in calendar year 2026 (UTC).
Orbital launch attempt: any launch intended to reach Earth orbit or beyond, including failures. Suborbital flights and tests not intended to reach orbit are excluded.
Launch provider: the company or agency operating the launch vehicle, classified by the country where it is headquartered. Launch site, customer and payload don’t matter. For example, a Rocket Lab Electron launch from New Zealand counts as “Other American provider”.
Source: Jonathan McDowell’s launch log (planet4589.org), with Wikipedia’s “2026 in spaceflight” as backup. If sources disagree on liftoff times, the primary source prevails.
Timing: resolution may be delayed by a few days into January 2027 to allow for confirmation of late-December launches.
