Anthropic IPO Surges as Fed Hike and Israel-Iran Ceasefire Odds Rise

Polymarket traders pushed Anthropic IPO odds to 96.6% while December Fed hike odds climbed to 79.5%. The latest prediction market news also shows the Israel-Iran ceasefire at 67.5%.

1. Will Anthropic IPO by December 31, 2026? – S-1 Filing Turns This Into a Live Deal

The Odds: YES at $0.9660 | NO at $0.0340 (Implied Probability: 96.6% to 3.4%)

The Trend: Yes jumped +10.20 pp in 24h [ YES: 96.6% ] ███████████████████░ [ NO: 3.4% ]

The Breakdown

This market resolves Yes if Anthropic shares are listed on a public securities exchange and begin trading by December 31, 2026. A public-company acquisition of Anthropic would instead force No. At $0.9660, the contract is pricing a near-certain listing, with only a small sliver of doubt left in the market.

The move is anchored in the company’s public S-1 registration statement filed with the SEC on November 9, which shifted the story from IPO speculation to an active regulatory process. Reporting said the earliest possible trading date was November 16, after the roadshow, pricing, and regulatory clearance. That is the kind of procedural step traders can actually price, and they did.

The Catalyst

The filing sharply reduced execution uncertainty, which explains why the market repriced so aggressively toward Yes. Even with valuation questions hanging over the deal, including reported concerns around a proposed valuation near $1.5 trillion and talk of a smaller offering or delay after an AI-stock selloff, the S-1 was treated as stronger evidence of completion than those concerns were evidence of cancellation.

This is a classic example of a market reacting to process, not hype. Once the SEC filing landed, the path to a public listing became concrete, and the contract moved to reflect that reality. The remaining gap is not about whether an IPO is possible, it is about whether the timeline slips or the structure changes before year-end.

The Bettor’s Angle

At 96.6%, there is not much room left for upside unless you think the market is still underestimating a delay. That makes fresh Yes entries look thin on value unless you are specifically playing for a near-term listing confirmation. The bigger risk is paying too much for certainty after the market has already moved hard.

If you want exposure, the better read is that this is now a timing trade, not a binary belief trade. Anyone leaning No is fighting both the filing and the market’s interpretation of it, which is a rough setup. Liquidity may still allow small tactical positions, but the edge has likely narrowed sharply after the repricing.

2. Will the Fed Increase Interest Rates by 25 Bps After the December 2026 Meeting? – Hawkish Odds Keep Climbing

The Odds: YES at $0.7950 | NO at $0.2050 (Implied Probability: 79.5% to 20.5%)

The Trend: Yes rose +3.00 pp in 24h [ YES: 79.5% ] ████████████████░░░░ [ NO: 20.5% ]

The Breakdown

This contract resolves Yes if the FOMC raises the upper bound of its target federal-funds range by 25 basis points at or after the December 8-9, 2026 meeting. At $0.7950, traders are leaning heavily toward another hike, with the No side still alive but clearly secondary.

The move was not isolated. The related “another Fed rate hike in 2026” market also rose 3.0 points to 78.5%, while the “no change” market fell 3.0 points to 19.5%. That tells you the repricing is broad across the Fed curve, not just a one-off adjustment in this contract.

The Catalyst

A stronger-than-expected October employment report revived expectations for another hike after markets had trimmed those bets amid fears that the AI-led selloff could weaken growth. Reuters said traders raised the implied probability of a December hike from roughly 67% to about 80%, which lines up neatly with the Polymarket move.

The logic is straightforward, resilient employment makes it easier for the Fed to worry that inflation stays above target. If policymakers think waiting carries more inflation risk than acting does, December becomes a cleaner hike window. The contract is basically pricing that policy bias in real time.

The Bettor’s Angle

This is a more tradable market than the Anthropic one because it still leaves room for disagreement. If you think the jobs data was a one-report overreaction, the No side has some appeal. But the move in the related contracts says the market is not treating this as a narrow bet.

For hedgers, the cleanest read is that the December hike thesis is now the consensus lean, not a fringe view. That usually makes late Yes chasing less attractive. If you want a contrarian angle, it has to come from believing the labor strength will fade before the meeting, not from ignoring the current repricing.

3. Israel-Iran Ceasefire Continues Through December 31? – De-Escalation Odds Improve

The Odds: YES at $0.6750 | NO at $0.3250 (Implied Probability: 67.5% to 32.5%)

The Trend: Yes jumped +10.00 pp in 24h [ YES: 67.5% ] ██████████████░░░░░░░ [ NO: 32.5% ]

The Breakdown

This market resolves Yes if neither Israel nor Iran conducts a qualifying air strike or surface-to-surface missile strike that directly impacts the other country through December 31, 2026. The contract is narrower than a broad peace bet, because it excludes threats, cyber operations, intercepted munitions, ground incursions, and several lower-level attacks.

That narrow definition matters. It means diplomatic calm has a direct effect on resolution odds, because the market is specifically pricing the chance of the exact actions that would trigger No. At $0.6750, traders are assigning a solid majority to continued calm, but there is still meaningful room for a disruption.

The Catalyst

On November 9, President Trump said the war was “effectively over,” described renewed strikes as unlikely, and pointed to positive momentum after discussions involving Qatar. Reporting also described a ceasefire proposal linked to renewed nuclear negotiations. Those developments materially lowered the perceived near-term chance of a qualifying strike.

The move was especially large because the contract’s resolution rules are so specific. A softer diplomatic backdrop does not just improve sentiment, it directly reduces the odds of the particular missile or air strike events that would settle the market to No. Shorter-dated ceasefire markets moved the same way, with the November 15 contract up 3.75 points, the November 22 contract up 5.0 points, and the November 30 contract up 7.0 points.

The Bettor’s Angle

This is the cleanest geopolitical read of the three main markets because the catalyst maps directly onto the resolution rule. If you think the current diplomatic channel holds, Yes still has room to grind higher. If you think one provocation can break the calm, the No side remains live and liquid enough to matter.

The shorter-dated contracts confirming the move are a useful signal, because they show traders extending confidence across the curve. That usually makes fading the trend harder unless you have a specific escalation thesis. For most bettors, the market is telling you the de-escalation trade is intact, not exhausted.

4. US-Iran Final Nuclear Deal by December 31, 2026? – Process Odds Improve, but the Bar Stays High

The Odds: YES at $0.1250 | NO at $0.8750 (Implied Probability: 12.5% to 87.5%)

The Trend: Yes rose +3.00 pp in 24h [ YES: 12.5% ] ███░░░░░░░░░░░░░░░░░░ [ NO: 87.5% ]

The Breakdown

This market resolves Yes only if the United States and Iran sign or formally adopt a written final agreement containing a concrete, measurable restriction on Iran’s nuclear program by December 31, 2026. That is a much stricter standard than a ceasefire or a diplomatic opening, which is why the Yes price remains low at $0.1250.

The contract is still moving in the right direction, though. Traders are clearly assigning some value to the possibility that current diplomacy can evolve into a formal nuclear instrument, even if the jump is modest compared with the ceasefire market.

The Catalyst

Reporting described a ceasefire proposal that could create space for renewed nuclear discussions, including negotiations over Iran’s uranium stockpiles. That does not prove a final deal is near, but it does create a plausible pathway toward one if talks keep advancing.

The linked-market evidence reinforces that read. The November 30 version rose 2.75 points to 5.05%, while the US-Iran Hormuz agreement market rose 2.5 points to 16.0%. Those synchronized moves suggest traders are pricing a broader improvement in US-Iran diplomacy, even if the final-deal threshold remains difficult to clear.

The Bettor’s Angle

This is a classic low-probability, high-standards market. The Yes side can move on diplomatic progress without the underlying event being likely enough to justify a big position. That makes it more suitable for small speculative exposure than conviction betting.

If you are looking for a cleaner trade, the ceasefire market offers the more direct expression of the same geopolitical theme. The final-deal contract is the lagging version of that story, and the market is treating it that way. The No side still looks dominant, even after the positive drift.

Editor’s Takeaway

The market is rewarding three very different stories, a near-certain Anthropic IPO, a firmer expectation of another December Fed hike, and a steadier Israel-Iran ceasefire path. The first is about execution, the second is about macro data, and the third is about geopolitics narrowing toward a specific outcome. None of them are priced as neutral, and that is the point, real-money traders are leaning hard into the probabilities they think are most likely to resolve.
