To better assess where each potential outcome stands, the market can be segmented into three distinct trading tiers based on implied probability and contract pricing:

🥇 Tier 1: The Dominant Leader

• No change (82%): Currently commanding the highest probability, No change is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 82¢, signaling a high degree of market conviction. This contract alone has generated $31.7K in volume.

🥈 Tier 2: The Primary Challengers

• 25 bps increase (18.5%): Positioned as the most viable alternative, 25 bps increase maintains a 18.5% chance of resolving true. Its “Buy Yes” shares currently trade at 19¢.

The Statement on Monetary Policy for the Bank of Japan's Monetary Policy meeting for October is scheduled to be released on October 30, 2026 (https://www.boj.or.jp/en/mopo/mpmsche_minu/index.htm).

This market will resolve to the amount of basis points the upper bound of the short-term policy interest rate is changed by versus the level it was prior to the Bank of Japan's October 2026 meeting.

If the short-term policy interest rate is changed to a level not expressed in the displayed options, the change will be rounded up to the nearest 25 and will resolve to the relevant bracket. (e.g. if there's a cut/increase of 12.5 bps it will be considered to be 25 bps)

The primary resolution source for this market will be the official website of the Bank of Japan (https://www.boj.or.jp/en/mopo/mpmsche_minu/index.htm), however a consensus of credible reporting may also be used.

This market may resolve as soon as the Bank of Japan's statement for the specified meeting with relevant data is issued. If no statement is released by the end date of the next scheduled meeting, this market will resolve to the "No change" bracket.

While human consensus and speculative volume shape the broader prediction market, our quantitative algorithms offer a data-driven counter-perspective. By analyzing fundamental signals, underlying trends and historical distributions, our AI Valuation model calculates an independent “Fair Value” probability for each outcome.

Comparing this Fair Value against the current Trade Value uncovers major disparities — known as the Expected Value (EV) Gap. Contracts with a positive EV Gap represent statistically underpriced outcomes, whereas a negative EV Gap flags a potential market overreaction.

Top AI Alpha & Mispriced Arbitrage Opportunities

Based on the latest data model run, several key contracts stand out with significant deviations:

• The Most Overvalued Outcome No change currently trades at 82%, but our AI places its Fair Value at just 62.6%. This creates a large negative EV Gap of -19.4%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies 25 bps increase as the premium value opportunity on the board. While the market only assigns it a 18.5% trading probability, our AI’s Fair Value assessment sits at 19.1% — yielding an impressive +0.6% EV Gap.
