660 wallets hold a record of at least 20 resolved Science events, ranked by skill-adjusted accuracy across distinct events, so one correlated position can’t pass as a track record. The public board is free to read. The current #1 is 0x69e7…d3b0, with 20 resolved events · +10.83¢ per share over the prices paid, after the sample-size adjustment · 83.9% hit rate at its Wilson lower bound. Its Science score, calibration diagram and graded history are free to read; the complete ranking behind it is the subscription. Scores are statistical estimates over public on-chain data, and they describe wallet records rather than persons. How the scoring works →
Free preview. The #1 forecaster’s identity and real numbers are shown. The rest are hidden, not blank.

The 5-minute price is the price of the first trade on the same outcome at least five minutes after each scored fill, whichever side started it (called the follower’s price on the research page). Each record in a category is re-priced there and measured before fees against the price curve, so the favorite-longshot premium anyone could get at that price is taken out. Held up means the average sat above zero at 95% confidence over at least 20 events at that price. Didn’t hold up means an average of zero or below over at least 20 such events, with no confidence test. Anything else has too little evidence for a verdict yet, including fewer than 20 events or a positive average short of 95%. The test treats a wallet’s events as independent, and related events can make a record look stronger than it is. It does not show whether buying at that price made money, and it is not the price a copier pays. In a pre-registered run on 2026-09-28, the taker price (the first purchase at the asking price, or for a sale the first sale at the bid, five or more minutes after each fill) cost 0.33 cents a share more on average, counting any price move in between. At that price, before fees, wallet-categories whose earlier records held up came out 0.21 cents a share below the price curve on later events, though about a cent a share better than the rest. Among records the board ranks above its baseline, the ones that didn’t hold up were not shown to do worse later than the rest (a pre-registered test on 2026-09-29). Labels as of September 27, 2026. The scores beside them are rebuilt nightly. A research label, not a recommendation to buy, sell, copy, or hold. How it was tested (the research page)
Scores are statistical estimates based on public on-chain data and may be incomplete or wrong. They describe a wallet’s historical record, and they are not statements about any person’s character, honesty, or overall trading ability. Wallet owner?

Science markets price research and regulatory milestones: FDA approval decisions, rocket launches, mission outcomes, and discovery announcements with deadlines. Resolution follows official decisions and documented events.
Approval and launch questions carry published schedules, public advisory processes, and delay-prone timelines, and the market's entry price states a testable probability against each deadline. Ranked wallets here have repeatedly judged those regulatory and engineering timelines better than the consensus.
The Weekly Skill Report. Each Monday, one free email counts the positions the alert feed first flagged last week and how many have since won or lost. It names the busiest categories and the ledger’s running total, and links to every graded row.
Regulatory decisions such as FDA approvals, launch and mission outcomes, and dated discovery or publication questions. Markets resolve on the official decision or documented event.
Where does edge come from in science markets?
Advisory committee signals, trial data, launch readiness reporting, and historical slip rates are public but require domain reading. Records that beat entry prices across independent decisions suggest that reading was better than the market's.
How do delayed outcomes grade?
A market resolves as written. An approval question with a deadline resolves yes or no on that deadline. Each date on a ladder is a separate yes-or-no market and counts on its own, so one delay can settle several graded events at once. Separate decisions carry the independent evidence.
