Planner reasoning

This is a low-base-rate 'formal US government action removes public access to a major AI model' question; the key drivers are pending federal actions against Chinese models (DeepSeek, Qwen, Kimi, GLM) such as the Decoupling America's AI Capabilities from China Act, Commerce/BIS export or import controls, and any executive orders. I need the Polymarket anchor price, current legislative/regulatory status, and news on any imminent action, plus cross-venue triangulation.

# Current state As of Polymarket data, YES trades at 17.5% (falling from a 45% peak, -13.5% over 30 days), reflecting market skepticism that a *general public* access removal will occur in 2026. No enacted formal action confirmed to have caused a lasting, model-wide public-access removal; government-device bans on DeepSeek exist but do not meet the "general public" bar. A disputed, unverified report claims a brief (18-day) Commerce-ordered shutdown of two Anthropic models in June 2026 that could already satisfy resolution criteria — this is the single most important open question for this market. # Timeline of key events - 2025-01-29 — S.321 "Decoupling America's AI Capabilities from China Act" introduced, 0 cosponsors as of 2026 (confirmed/stalled). [congress.gov] - 2025 (ongoing) — Commerce, Navy, and several states ban DeepSeek on government devices only; no public ban (confirmed). [conference-board.org] - 2025-12-11 — Trump EO on state AI-law preemption signed; unrelated to model access removal (confirmed).

[explainx.ai] # Event Will a formal US federal action (legislation, EO, export control, etc.) cause general removal of US public access to a major AI model (from a specified list of companies) at any point before Dec 31, 2026? # Outcomes to forecast Yes / No # Kalshi market anchor No Kalshi-direct price was returned for this ticker in research; only unrelated Kalshi markets surfaced via keyword search (no DeepSeek/AI-regulation matches). Best available cross-platform anchor: Polymarket YES = 17.5%, down from a 45% high, -4% (7d) and -13.5% (30d), on thin volume ($18.2K total, 54 days of data) — a declining, low-conviction market. # Sub-question answers 1. **Polymarket price/history/volume** — 17.5% currently, high 45%/low 14.5%, down sharply over 30 days, $18.2K total volume (thin). [polymarket_direct] 2. **Pending legislation (Decoupling Act, No Adversarial AI Act)** — Both stalled; S.321 has 0 cosponsors since Jan 2025; No Adversarial AI Act only covers federal procurement/devices, not public bans. Neither is close to enactment or would remove *public* access. [congress.gov, therecord.media] 3. **2025-2026 EO/BIS/FCC signals targeting public access to DeepSeek/Qwen/Kimi/GLM** — Only device/procurement bans confirmed; broader Entity List/EO options against Kimi/Qwen were under White House consideration as of July 2026 but nothing signed by month's end; First Amendment/enforceability concerns cited as obstacles. [fastcompany, machinebrief, bivashvlog] 4. **Historical base rate** — No confirmed precedent of full US public removal of a major AI model via federal action; closest analogies (TikTok divest-or-ban, Huawei, Kaspersky) involved apps/hardware, took years, and are imperfect analogies for AI models. One unverified 2026 report (Anthropic Fable5/Mythos5) would be the first such precedent if confirmed. [theconversation.com; code_execution base-rate model] 5. **Domestic lab enforcement threats (OpenAI/Anthropic/Meta/xAI)** — June 2026 EO created voluntary pre-release government review of closed frontier models; OpenAI complied voluntarily (GPT-5.6, no legal order) and released publicly Jul 9; disputed report of a Commerce-ordered Anthropic shutdown exists but is unverified. [hsfkramer, cybersecuritydive, theconversation.com] 6. **Related Kalshi/Polymarket pricing** — No matching Polymarket markets on DeepSeek/AI ban/OpenAI found (0 of 100 scanned); no relevant Kalshi markets found beyond this ticker. No independent cross-market confirmation available. # Key facts (high-confidence, factual) 1. [congress.gov] S.321 (Decoupling Act) stalled, 0 cosponsors, introduced Jan 2025. 2. [conference-board] Federal/state DeepSeek bans are device/procurement-only, not public bans. 3. [hsfkramer] June 2026 EO created voluntary pre-release review for closed frontier models; open-weight models exempt. 4. [cybersecuritydive/gcn] GPT-5.6 delayed voluntarily, then released publicly July 9, 2026 — no legal removal occurred. 5. [bivashvlog] No EO/regulation targeting Chinese public models signed as of July 20, 2026. # Cross-market signals - Kalshi related: no DeepSeek/AI-regulation markets found; only unrelated tickers surfaced. - Polymarket: no related AI-ban/DeepSeek/OpenAI markets found (0/100 scanned) for cross-checking. - Sportsbook implied: none available/applicable. # Analyst opinions and speculation - Multiple outlets (Fast Company, Tom's Hardware) frame a Chinese-open-weight-model ban as technically near-unenforceable given downloadable weights, and warn it could "strengthen Beijing's hand." - White House internal split (Sacks, Krishnan vs. hawkish factions) reduces near-term likelihood of a broad EO. - The Anthropic "Fable5/Mythos5" story, if accurate, would be a landmark precedent-setter, but the model names are unrecognized/unverifiable and may reflect a research-tool hallucination — treat as low-confidence/rumored, not established fact. # Directional lean per outcome - **Yes**: Active White House deliberation on Chinese-model Entity List/EO (Kimi/Qwen), broadened closed-model review framework, and one disputed report of an actual (if brief) forced shutdown — some real momentum toward a qualifying action, especially if disputes over Chinese model access escalate late 2026. - **No**: All confirmed actions to date are device/procurement bans (not public-access removals) or voluntary compliance (not government mandate); legislative routes stalled with zero cosponsors; internal administration opposition; enforceability/First Amendment concerns on any weights-level ban; Polymarket trending down to 17.5%. # Gaps / unknowns - Whether the Anthropic Fable5/Mythos5 incident is real, and if so, whether it counts as "major AI model" (flagship vs. preview) under the rules. - No direct Kalshi YES price was retrieved for this specific ticker. - Unclear whether any Commerce Entity List action against Kimi/Qwen/GLM will be finalized before year-end 2026. # Calibration anchors - Polymarket YES (proxy anchor): 17.5%, declining. - Base-rate model (code_execution): ~5–9% (point estimate ~6-7%) absent a confirmed triggering event. - Historical precedent: essentially none for full US public removal of a major AI model via federal action (TikTok/Huawei analogies imperfect, multi-year processes).

1. Both forecasters anchor tightly to Polymarket's 17.5% and barely deviate, despite explicitly noting this market is "thin" ($18.2K volume, 54 days) and "low-conviction" — neither explains why a thin, declining market should be trusted over the base-rate model's 5-9% estimate, which both cite but effectively ignore in favor of the anchor. 2. Neither forecast adequately grapples with resolution ambiguity: if the Anthropic Fable5/Mythos5 report is even partially true (an 18-day global shutdown already occurred in June 2026), the question could already resolve YES retroactively regardless of what happens the rest of the year — this is flagged in the brief as "the single most important open question" but both forecasters dismiss it with roughly equal, seemingly arbitrary weight (14% vs 17%) without decomposing P(event occurred) × P(it counts under resolution criteria). 3. Neither forecaster meaningfully weighs the escalation trajectory: the brief shows increasing momentum (June EO expanding review scope, July White House "reviving consideration" of Entity List action against Kimi/Qwen, August framework explicitly keeping closed US models "in scope") — this pattern of ratcheting actions across 2026 suggests rising rather than flat risk into Q4, which a static 14-17% doesn't capture. 4. The two forecasts are nearly identical in reasoning and output (0.14 vs 0.17), suggesting insufficient independent analysis — one anchors "slightly below" market and the other "at" market, but neither stakes out a distinct view on the actual probability the Anthropic incident is real, which is the one lever that could move this dramatically. 5. Neither forecast considers the "specified list of companies" scope constraint explicitly — if Kimi/Qwen/GLM (Chinese open-weight models) are excluded from the resolution list because the August framework "exempts open-weight US models" (implying non-US models might be differently categorized), the entire Entity List escalation narrative driving YES-side risk could be irrelevant, which would push probability lower than both estimates. 6. Both treat the GPT-5.6 voluntary withholding and DeepSeek device bans as clearly non-qualifying, but neither addresses whether a future "voluntary" compliance under implicit government pressure (as with GPT-5.6) could later be characterized as a de facto forced removal for resolution purposes — this gray zone between "voluntary" and "ordered" is unresolved and could shift probability mass either direction.

13% (55% confidence)

Yes: 13% No: 87%

Every confirmed federal action to date falls short of the resolution bar: DeepSeek restrictions are device/procurement-only, the June 2026 EO created a voluntary pre-release review (with open-weight models exempt), and GPT-5.6 was voluntarily withheld then publicly released July 9. Legislative routes are dead (S.321 at 0 cosponsors), Entity List action against Kimi/Qwen remains unsigned amid an internal White House split plus enforceability and First Amendment obstacles. The one report that would resolve YES (Commerce-ordered Anthropic 'Fable 5'/'Mythos 5' shutdown) uses model names that match no real Anthropic products and is most plausibly a research-tool fabrication; decomposing, P(real) is perhaps 0.15-0.20 and P(counts as a 'major model' general public removal | real) maybe 0.5, contributing only ~7-10 points at most, and the falling market price is itself evidence the incident isn't recognized as qualifying. Balancing the thin, declining 17.5% proxy anchor against a 5-9% structural base rate and the scope ambiguity around which companies are listed, I settle modestly below the market at 13%, leaving room for late-2026 escalation risk.
