Market context
SpaceX’s thirteenth Starship flight test aborted cleanly at T‑0 on Thursday, 16 July, when several engines failed to start, triggering an automatic launch hold just before liftoff from Starbase, Texas[1][3]. The vehicle, comprising Booster 20 and Ship 40 (both Block 3), was cleared for launch after the FAA closed its investigation on 13 July, but no official cause has been confirmed yet[3][4]. A new attempt is expected “hopefully” within a few days, with the next window now listed as NET 17 July[3][4].
Historically, early Starship test flights have seen multiple T‑0 or pad‑side aborts before achieving full missions: Flight 1 suffered an engine‑out during ascent, Flight 2 lost a booster early, and Flight 3 achieved the first successful upper‑stage splashdown after earlier failures[8]. Compared with those cases, a single T‑0 abort on a mature Block 3 stack is less severe, yet the current 0 % YES implied probability on best‑prediction‑markets.co.uk diverges sharply from analyst consensus that a re‑try within days is likely, and from sportsbook lines on related “next launch” contracts that still price a 60–70 % chance of a successful Flight 13 attempt in the coming week[3][4].
Traders should monitor SpaceX’s official X feed and the launch‑schedule page for a confirmed re‑try date, the 90‑minute window opening at 22:45 UTC, and any range‑status updates[1][2]. Key catalysts include the resolution of the engine‑start anomaly, final static‑fire checks on Booster 20 and Ship 40, and any FAA or range‑clearance notes that could delay the next attempt[3][7]. The mission’s primary objectives—deploying 20 Starlink V3 satellites and testing upper‑stage splashdown in the Indian Ocean—remain unchanged pending a successful launch[2][9].
Methodology
This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Best Prediction Markets UK, which mirrors the Polymarket order book directly.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
