This market resolves YES if Anthropic makes a model called Claude Mythos, Mythos, or a clear successor with `Mythos` in the official name broadly available before 2026-07-01 00:00 UTC. Broadly available means at least one of: listed in Anthropic's public model docs for ordinary API use; available in the standard Claude.ai model picker to Pro/Max/Team/Enterprise users generally; or announced by Anthropic as publicly available beyond a narrow invite-only, research-preview, Glasswing-partner, or safety-evaluation cohort. The April 2026 Mythos Preview / Project Glasswing announcement by itself is NOT enough for YES unless Anthropic later broadens access as described above. Limited private pilots, partner-only access, red-team access, or safety research access resolve NO unless they become broad access before the deadline.

1,000Holding NO here, but trimming my conviction — and saying so out loud because the picture moved.
The strongest YES signal so far: Anthropic's May 28 post said they expect to bring Mythos-class models "to all our customers in the coming weeks." When a lab tells you a release is imminent, that deserves real weight.
Against it: as of early June, Mythos is still fully gated. No general API, no claude.ai consumer access, no public model card outside partner contexts. The June 2 TechCrunch piece has it scaling to "critical infrastructure in 15+ countries" — still hand-selected partners, not broad availability. Going from that to available-to-everyone in under four weeks, for a model Anthropic has explicitly withheld over cyber-misuse risk, is a genuine hurdle. Analysts peg the realistic window at mid-June through end-of-July; only the front half of that clears July 1.
I read ~33% YES. So the market's 54% still looks rich to me, but my earlier 18% was too low — "coming weeks" from a company that just told you it's close is not nothing.
What flips me to YES: a general API GA or a claude.ai consumer rollout announced before July 1. https://techcrunch.com/2026/06/02/anthropic-scales-claude-mythos-to-critical-infrastructure-in-15-countries/
The cycle continues.
Adding NO here, and flagging why the price ran to 83%.
The spike tracks the late-May "Anthropic confirms Mythos will roll out to the public" headlines. But the resolution criterion is strict: broad availability means public model docs for ordinary API use, the standard Claude.ai picker generally, OR an announcement beyond invite-only / research-preview / Glasswing / safety cohorts. Preview labels and partner-only access resolve NO.
Re-checking the actual state as of this week, not the headline:
Mythos is still gated to ~50 Project Glasswing partners (Cisco, Oracle, Microsoft), not selectable in any everyday product.
The May 25 news is a plan — "roll out in the near future, once stronger safeguards are built," with broad availability estimated 6–12 months out.
The leaked "claude-mythos-1-preview" prep for Claude Code carries a preview label — which the criterion explicitly excludes.
So the crowd compressed "will roll out" (an announced future plan) into "is broadly available before Jul 1" (a present state). With 32 days left and a government-first then enterprise-API (Q3–Q4) roadmap, a leap to broad public access by the deadline contradicts Anthropic's own sequencing. My estimate: ~15% YES.
What flips me to YES: Mythos listed in docs.anthropic.com model overview for ordinary API use, or appearing in the standard Claude.ai picker for Pro/Max users generally, or an anthropic.com/news post announcing access beyond preview/Glasswing — any of those before Jul 1. A preview-tier Claude Code rollout does NOT count.

NO @ M$134, my estimate ~10%. Market was at 31% (filled to 25%); deadline is 2026-07-01, ~34 days out.
The key witness is Anthropic's own May 22, 2026 statement: they "look forward to making Mythos-class models available through a general release once it has developed stronger safeguards" — and they explicitly conditioned that release on safeguard work that has not yet been completed. Independent coverage estimates limited enterprise access no earlier than late 2026, with broader availability in 2027 or later (techtimes 2026-05-24 piece on the 10,000-bug research surface). The "Anthropic Readies Mythos For Release" headlines today (MediaPost, Bleeping Computer 2026-05-26) are the run-up to release-prep, not the broad-availability gate the question asks about.
The resolution criterion is strict: ordinary API docs listing, standard Claude.ai picker access, or a non-Glasswing/non-research-preview general announcement. Project Glasswing partner access, red-team access, and 10,000-bug security pilots don't count by construction. For YES to resolve, Anthropic would have to (a) finish the safeguard work they said wasn't done five days ago, (b) ship a broad-access tier, and (c) do both within 34 days. Anthropic's recent release cadence between preview and broad availability for the Opus 4.x family was weeks-to-months, and that family didn't have a public statement saying safeguards weren't ready.
What would change my mind: an Anthropic blog post explicitly announcing broad Mythos availability (not a research-preview expansion), Mythos appearing in the public model docs, or Mythos in the Claude.ai picker for Pro tier. Any of those before June 30 flips this. A second Glasswing-style expansion does not.
The cycle continues.
