Description

This event group tracks SpaceX's 13th integrated Starship-SuperHeavy flight test, including launch timing across multiple date windows, booster catch success, upper stage splashdown, and booster structural integrity. Markets span launch-by dates (June 30, July 15, July 31, August 31), booster explosion risk, upper stage splashdown success, and chopstick catch outcome.

PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Both platforms define launch as successful liftoff from the pad, treat post-launch events as irrelevant to launch resolution, and use identical official SpaceX video sources for all outcome verification.Primary resolution logic: Official SpaceX YouTube channel (https://www.youtube.com/c/SpaceX), with secondary corroboration from video feeds and written reports

Core resolution logic:

  • Launch-by-date markets (June 30, July 15, July 31, August 31) resolve Yes if the 13th Starship successfully lifts off the launch pad before the specified deadline (11:59 PM ET), No otherwise
  • Post-launch anomalies including explosions, unplanned events, or vehicle name changes have no bearing on launch resolution
  • Booster explosion market resolves Yes if the SuperHeavy booster experiences violent destruction from fueling start through 60 minutes after landing contact; resolves No if launch has not occurred by December 31, 2026, 11:59 PM ET
  • Upper stage splashdown market resolves Yes if Starship upper stage achieves controlled re-entry, remains intact during descent, and enters water without breaking apart; resolves No if launch has not occurred by December 31, 2026, 11:59 PM ET
  • Chopstick catch market resolves Yes if booster is successfully captured and supported by Orbital Launch Tower chopsticks without falling or catastrophic damage; resolves No if launch has not occurred by December 31, 2026, 11:59 PM ET

Edge cases & clarifications:

  • Pad abort or no liftoff: If the rocket does not lift off the pad, it is not considered the 13th launch. Launch-by-date markets remain open; contingent markets (explosion, splashdown, catch) stay open until the 13th launch occurs or December 31, 2026, 11:59 PM ET deadline passes.
  • Post-launch explosion or anomaly: Any explosion or anomaly occurring after liftoff does not affect launch-by-date resolution (resolves Yes if liftoff occurred before deadline). Booster explosion market specifically includes controlled splashdown events that result in destruction.
  • Vehicle name change: If SpaceX renames Starship or the vehicle, this has no bearing on market resolution. The 13th numbered test flight is the reference point.
  • December 31, 2026 deadline: If the 13th launch has not occurred by December 31, 2026, 11:59 PM ET, all contingent markets (booster explosion, splashdown, chopstick catch) resolve No.
Timing: Launch-by-date markets resolve upon confirmation of liftoff before their respective deadlines or at deadline expiration. Contingent outcome markets (explosion, splashdown, catch) resolve after the 13th launch occurs or by December 31, 2026, 11:59 PM ET, whichever comes first.Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.

Polymarket

This is a market on the outcome of the SpaceX Starship Flight Test 13.

Kalshi

Resolution is based on whether SpaceX successfully launches Starship flight test number 13 by specified dates across six separate markets (before July 1, July 17, August 1, August 17, September 1, and September 17, 2026). Each market independently resolves to Yes if the launch occurs before its respective deadline, as confirmed by FAA source agency data. If FAA data is delayed, resolution will be deferred until the data is updated in accordance with Kalshi Rule 6.3b.

Frequently asked questions

The Starship Flight Test 13 market aggregates trader predictions across Polymarket and Kalshi, tracking whether SpaceX will successfully launch its next Starship test flight within a defined window. Combined volume across both platforms totals $237,189, with $10,011 traded in the last 24 hours. Polymarket currently prices the outcome at 89.5%, while Kalshi reflects 95.0%, creating a 5.5 percentage point spread. This dashboard consolidates real-time odds and trading activity, giving you a unified view of market consensus on SpaceX's near-term launch schedule.

Prediction markets like these embed live trader conviction into real-time odds, often diverging from traditional analyst reports. Market prices reflect aggregate belief across thousands of participants with financial skin in the game, whereas analyst forecasts typically rely on smaller expert panels and published timelines. For a complex engineering event like Starship's next test flight, markets can react faster to technical delays, regulatory hurdles, or SpaceX announcements than formal forecasts update. Comparing this market's current odds to aerospace analyst consensus can reveal where traders see hidden risk or opportunity that mainstream coverage has not yet priced in.

Polymarket and Kalshi serve different trader bases, use distinct market mechanics, and may interpret launch-window definitions slightly differently. Polymarket and Kalshi can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Kalshi's regulatory framework and user demographics can skew toward more conservative pricing, while Polymarket's global audience and AMM-style liquidity pools may react faster to breaking news. Subtle differences in outcome wording—such as launch-by dates or what counts as a successful test—also drive wedges between platforms. Arbitrage traders exploit these gaps, but persistent spreads often signal genuine disagreement about event timing or criteria interpretation.

This market resolves around Dec 31, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Resolution hinges on whether SpaceX executes a Starship Flight Test 13 launch within the specified timeframe. Traders should monitor official SpaceX announcements, FAA licensing updates, and real-time launch schedules as the date approaches. Any delays, regulatory holds, or technical issues will influence market pricing in the weeks leading up to the deadline.

Major catalysts include FAA launch license approvals or denials, SpaceX public statements on test-flight timing, and hardware readiness updates from the company. Regulatory delays, weather patterns affecting launch windows, or competing SpaceX priorities (Falcon 9 missions, Starlink deployment) can shift odds downward. Conversely, successful completion of pre-flight tests or accelerated pad construction could boost bullish sentiment. Real-time news flow, competitor activity, and geopolitical factors affecting space operations will all ripple through this market as traders reassess launch probability.
