This market asks whether SpaceX or Tesla will have the higher valuation at the end of June 30, 2026. It is worth watching because it compares a private company and a public company using different valuation sources, so the answer depends on official price data rather than a simple headline number.
The question is which company will be valued higher on June 30, 2026: SpaceX or Tesla. For Tesla, the market uses the official closing price of its publicly listed shares on the primary exchange, multiplied by outstanding common shares; for SpaceX, it uses the final NPM Price reported by Nasdaq Private Market, LLC. The listed resolution date is July 1, 2026, with a fallback window through July 4 if NPM has not yet published the relevant data.
SpaceX and Tesla are both closely followed companies, but they are valued through very different mechanisms. Tesla’s value can change every trading day with the stock market, while SpaceX’s valuation is based on Nasdaq Private Market’s published private-company pricing, which is updated on a separate schedule and may not be available for every date in the same way. That creates a concrete uncertainty around which valuation source will end up higher on the specific date the market checks.
For Tesla, the biggest drivers are its official closing share price on June 30 and any news that changes market expectations about the company’s equity value before that date. For SpaceX, the key factor is the NPM Price published for June 30, or the most recent available NPM data if that date is not yet posted by the resolution deadline. Any change in the timing, availability, or continuation of NPM coverage could matter because the rules allow fallback resolution using the latest published data.
The current market price implies roughly a 90% chance for the leading outcome, based on live Polymarket pricing. That number is not a prediction from PredictionNinja and it is not a guarantee; it is the current crowd-priced view of the market and can change quickly when new information appears.

View marketReaders should verify the final June 30, 2026 Tesla closing price, the corresponding NPM Price for SpaceX, and whether NPM has published the June 30 data by 1:00 PM ET on July 1, 2026. If it has not, the market can remain open until 11:59 PM ET on July 4, 2026 and then resolve using the latest available information. The main ambiguity to watch is whether SpaceX remains covered by NPM and whether either company has changed status in a way that triggers the IPO or direct-listing rule.

This market is currently listed with an end date of Jul 1, 2026. Market timelines can change if the underlying event is postponed, rescheduled, or resolved early.
This market will resolve to the listed company with the larger valuation, as measured by the final NPM Price reported by Nasdaq Private Market, LLC (NPM) and the official closing price for the public company, for June 30, 2026. NPM Prices are published for trading days only and are updated once daily at 1:00 PM ET on the following calendar day. If NPM has not published relevant data for the specified date by 1:00 PM ET on July 1, 2026, this market may remain open until 11:59 PM ET on July 4, 2026. If no further data is released by that time, the market will resolve according to the latest data available. If NPM ceases publishing relevant data prior to the specified date, this market will resolve based on the NPM data published prior to the cessation of coverage, as well as applicable public market capitalization data following an IPO or direct listing. If the private company completes an IPO or direct listing before the specified date, this market will resolve according to the company's public market capitalization at the market close of the specified date or the most recent trading day. Public market capitalization will be determined using the final official regular-hours trading price published for the company's primary listed common equity on its primary exchange for the specified date or the most recent trading day, multiplied by the company's total outstanding common shares at the relevant time. If a listed company merges with or acquires another entity and remains the parent company, no change to resolution methodology applies. If a listed company is acquired, merges into another entity and is no longer the surviving parent company, or otherwise ceases to exist as an independent entity prior to the end of the period, only the NPM valuation and applicable public market capitalization achieved prior to completion of the transaction will be considered for resolution. No transaction, acquisition, or merger consideration will be considered for resolution. The resolution source for the private company is NPM data published here (https://fe.secondmarket.com/companies/company-5bc8aa2b-22b5-48cc-b54a-1310145b0a86/data?return_url=https://polymarket.com/finance/privates. The resolution source for any period following an IPO, direct listing, or relevant corporate action, will be official exchange trading data and publicly reported share counts. If SpaceX's valuation is equal to Tesla's public market capitalization at resolution, this market will resolve to 50-50. Revisions to previously published NPM data made after their initial release will not be considered, unless made to correct clearly erroneous data.
