Market context
Elon Musk’s wealth is being measured off a volatile mix of Tesla equity, SpaceX exposure and other private holdings, so the market outcome on 31 July will mostly reflect how those valuations settle rather than any single operating update. Bloomberg’s Billionaires Index currently shows Musk at about **$942bn**, while other trackers have been lower or higher at different points in July, underscoring how quickly his paper fortune can move with stock and private-market repricings.[2][1][12]
That history matters for reading the current **93% YES** probability: Musk has already spent parts of 2026 above the trillion-dollar mark and then back below it, with reports in July putting him anywhere from roughly **$709bn** to more than **$900bn** depending on the source and timing.[9][5][12] Bloomberg’s own profile has him at **$942bn** now, which suggests the market is pricing a continuation of that high-wealth band into the settlement point rather than an abrupt break lower.[2]
The main catalysts to watch are Tesla’s share performance into the close, any fresh repricing of SpaceX after its IPO-related gains, and whether Bloomberg updates Musk’s private-stake valuations before the resolution window shuts.[2][13][17] A large swing in either Tesla or SpaceX could move him materially across the relevant bracket, and recent reporting has shown that his net worth can change by tens of billions within days when those names re-rate.[9][17][10]

FAQ
- When do sports markets resolve?
- Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.
- Can I bet on individual matches?
- Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.
- What are live sports odds on Polymarket?
- Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
- What's the difference between match odds and outright odds?
- Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
- Can I import form data and lineups?
- This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
