Polymarket lists Ethereum price and SpaceX valuation markets for October 2026
Polymarket has listed two new prediction markets for October 2026. An Ethereum price market went live on October 18, 2026, with real-time odds available. A separate SpaceX valuation market, including a contract on whether SPCX shares reach $150, launched on October 16, 2026. Neither source disclosed trading volume, open interest, or current pricing levels for either contract. Both are short-dated binary contracts on asset prices that Polymarket has previously covered in other expiry windows.
The dual listings extend Polymarket's push to dominate short-dated crypto and pre-IPO verticals that Kalshi has not contested. For traders, the Ethereum contract overlaps with existing Bitcoin and STRC October markets, splitting already-thin crypto capital across four parallel strike structures rather than concentrating it.
The SpaceX contract feeds directly into the running Tesla-SpaceX merger narrative that traders price Tesla-SpaceX merger at 62.5% by 2027, but offers no listed volume or liquidity data, so directional bets may face wide exit spreads. Both contracts expire within weeks, which compresses the window for any price catalyst to materialize and rewards rapid position turnover over buy-and-hold structures. The platform's credit rides on whether these markets standardize into recurring monthly fixtures rather than one-off novelties.
