How boundaries are counted

Down includes its boundary: a rate of exactly 0.8534 counts as Down.

Up includes its boundary: a rate of exactly 0.8707 counts as Up.

Within is strictly between 0.8534 and 0.8707. The three outcomes cannot overlap and always sum to 100%.

Down includes its boundary: a rate of exactly 0.8190 counts as Down.

Up includes its boundary: a rate of exactly 0.9052 counts as Up.

Within is strictly between 0.8190 and 0.9052. The three outcomes cannot overlap and always sum to 100%.

Down includes its boundary: a rate of exactly 0.7759 counts as Down.

Up includes its boundary: a rate of exactly 0.9483 counts as Up.

Within is strictly between 0.7759 and 0.9483. The three outcomes cannot overlap and always sum to 100%.

Down includes its boundary: a rate of exactly 0.4310 counts as Down.

Up includes its boundary: a rate of exactly 1.2931 counts as Up.

Within is strictly between 0.4310 and 1.2931. The three outcomes cannot overlap and always sum to 100%.

AI average for the ECB reference rate for Thursday, 31 Dec 2026, from the 0.8621 reference. Rates are euros per US dollar. All four thresholds are on this page; choosing one updates the panels above.

Within ranges exclude both boundaries. Wider thresholds always have a larger Within share: the estimates nest consistently. A 50% move in a major currency pair is extremely unlikely; the estimate is shown rather than hidden so all four thresholds stay comparable. Values shown as “<0.1%” or “>99.9%” are bounds; the underlying values sum to 100%.

AI average — method

Simple mean of the OpenAI and Claude probabilities for each outcome, rounded so the three sum to 100. Uncalibrated: it has not been adjusted using settled outcomes.

Both models receive the same evidence pack and reference price, so their estimates are not statistically independent. Averaging two runs does not double the information.

OpenAI — run details

Model: [OpenAI model ID from run metadata] · Run: 31 Oct 2026, 06:09 UTC · Evidence pack: [pack ID]

Returns a probability distribution over 26 return bins; all four thresholds are computed from it. Checked to sum to 100 and to nest across thresholds before publishing.

Claude — run details

Model: [Anthropic model ID from run metadata] · Run: 31 Oct 2026, 06:10 UTC · Evidence pack: [pack ID]

Returns a probability distribution over 26 return bins; all four thresholds are computed from it. Checked to sum to 100 and to nest across thresholds before publishing.

Statistical reference — method

Synthetic fixture: lognormal rate at the target with zero median change and 3.3% volatility over the horizon (about 8% a year).

A simple baseline from price history. It is not a market-implied (risk-neutral) estimate, and no claim is made that it is more or less accurate than the models.

Why these estimates?

Directional factors follow the quote (euros per US dollar): “higher” means USD/EUR rises. Each item says whether it is a reported fact or the model’s inference.

What could push USD/EUR higher?

  1. Firm US data Model inference

    Strong US data before the 9 Dec FOMC decision could keep US yields high and support the dollar against the euro. 3 7

  2. Weaker euro-area growth Model inference

    Soft euro-area activity data could raise expectations of further ECB easing at or after the 17 Dec meeting, weighing on the euro. 4 6

What could push it lower?

  1. Narrowing rate gap Model inference

    If the Federal Reserve cuts faster than the ECB, the interest-rate gap that favours the dollar would narrow, which tends to strengthen the euro against the dollar. 1

  2. [Reported fact] Reported fact

    [Fact quoted from source 2 with its own date, for example a published inflation figure.] 2

Prediction-market context

No matching market Related market: none Checked 31 Oct 2026, 06:05 UTC

No contract on USD/EUR settles near December 2026, and no related contract was found. Market evidence is left out rather than shown as 0%.

Options-implied (risk-neutral) estimates are a different kind of evidence and are not shown in this version. How sources are matched

What this forecast may miss

  • Moves between fixings. The ECB rate is one daily observation; market rates at other times can differ.
  • Weekend news. Anything after 31 Oct 2026, 06:12 UTC enters only with a new version.
  • Calibration. Very few USD/EUR forecasts have settled; the AI average is uncalibrated.
  • The inverse pair. EUR/USD has its own page. Its thresholds are measured on EUR/USD, so its numbers are close to, but not an exact mirror of, this page. Its history is not independent evidence of accuracy.
