How it resolves
Resolved by whoever created the market, at their discretion per the question's description. It's play-money (Mana) and not tied to an official source — treat it as a community forecast.
Resolution criteria
The fine tuning problem in physics is an observation that multiple fundaental physical constants seem to independently fall into relatively small intervals enabling the existence of life. The Strong Anthropic Principle is a proposed explanation for fine tuning which posits the existence of multiple universes or parts of the universe with different values of basic constants. In a multiverse like that we necessarily find ourselves in the part which support the existence of life and consciousness. Each option in this question will be resolve based on one of the following: If a poll is conducted among physicists about the most likely explanation for fine-tuning, its results are used directly. The poll should be reasonably representative. In absence of such poll, I'll try to find at least 2 professional physicists (preferably Manifold users) and ask them whether in their opinion Anthropic Principle is the preferred explanation of fine tuning among physicists. Note: I will not be asking whether they personally believe this explanation, but whether it's the preferred explanation in the field. If previous options don't resolve the question, I'm going to ask the best available at the time version of ChatGPT or another AI, whether they think Strong Anthropic Principle is accepted as most likely true in physics community. As soon as one of these methods unambiguously point to Strong Anthropic Principle being accepted, I'll resolve all remaining options to YES. Otherwise the options will resolve to NO as soon as the respective period is over. Astronomers and cosmologists count as physicists for the purposes of this question. Philosophers do not, except those that also hold a PhD in Physics or Astronomy. In case the research in Physics gets dominated by AIs, I will try to adapt the resolution criteria to gauge their opinions. If this is for some reason impossible, I might resolve some of the options as N/A. I do not bet on my own questions. Update 2026-01-07 (PST) (AI summary of creator comment): For the Strong Anthropic Principle to be accepted as the most likely solution for fine-tuning, physicists must consider it likely that we live in a multiverse with varying cosmological constants. Without assuming the existence of a multiverse, the Strong Anthropic Principle does not resolve the fine-tuning question.

Apple Announces AI Glasses by September 30, 2026
The field is moderately concentrated with the 'No' side leading at 62%, but the 45% sum for two candidates indicates significant overlap or mispricing; the biggest recent shift is Meta's June 23 launch of $299 smart glasses (Forbes, Jun 23), which likely boosted the 'No' side by making Apple's entry seem less urgent or unique.

Will Anthropic release its next Mythos-class model to the public by August 31, 2026?
Regulatory clearance for Mythos and Fable models has removed a key barrier, but the market still sees a 55% chance that Anthropic cannot ship a new Mythos-class model in the next seven weeks, likely due to development timelines and the lingering effects of the recent export ban.
Yes ≈ 46% chance
Companies to go public in 2026
The field is extremely concentrated on SpaceX and Anthropic, whose combined odds (161%) imply the market expects at least one of them to go public in 2026, but the lack of recent headlines about either company's IPO process leaves the high probabilities unexplained by concrete events.
