What is Bciino?
The platform that rewards your knowledge and research
Forecast Numbers
Browse open challenges. Each one asks you to predict a specific measurable outcome — a price, score, count, or measurement.
Skill Wins
The winner is whoever submits the most accurate prediction. Do your research, analyse the data, and beat the competition.
Win Coins & Prizes
Top forecasters share the prize — play-money coins on most challenges, with real sponsored prizes on selected competitions.
How to Enter a Challenge
Four simple steps
Find a Challenge
Browse the challenge feed. Each challenge shows the question, prize pool, lock time, and official result source.
Submit Your Prediction
Enter your best estimate before the lock time. Coin challenges are free to enter — you play with coins. Sponsor-funded challenges are free to enter — the sponsor pays the prize.
Wait for the Result
After the lock time, no new entries are accepted. The official result is drawn from the source after the resolution time. Most results are confirmed by our admin team before payout.
Winners Announced
Absolute errors are calculated for all entries. Lowest error wins. The prize pool is distributed across 5 ranked places plus an accuracy pool, paid within 7 business days.
How Winners Are Decided
Pure skill. Pure math. No randomness.
Official Result Published
Each challenge specifies a question and an official source. The official result is drawn from that source after the challenge's resolution time. Most challenges are confirmed by our admin team before any payout is finalised; certain challenges may be finalised automatically from a trusted, deterministic source. All results are subject to our dispute process.
Absolute Error Calculated
For each entry: error = |your prediction − official result|. The participant with the smallest error wins first place.
Tie-Breaking Rule
If two or more participants have identical absolute errors, the participant who submitted their prediction earliest wins the higher ranking. Some formats split the prize equally among tied entrants.
Prizes Distributed
Top 5 participants are ranked, plus an accuracy pool for close predictions. Prizes sent within 7 business days. All rankings and errors published transparently after the challenge closes.
Disputes & Holds
If a result looks wrong, any participant can raise a dispute. Payouts are held for a review window after resolution so a dispute can be investigated before any prize moves. Upheld disputes void or correct the result; dismissed disputes release the payout. See our Terms of Service for the full process.
Prize Breakdown
Transparent splits, paid fast
How prizes are funded
📌 Coin challenges (most challenges): the coin entry pool is split among the top scorers — no platform fee, 100% to players
📌 Sponsor-funded challenges: no platform fee — 100% of the sponsor's prize goes to winners. A processing fee is charged to the sponsor on top of the prize to cover payment costs; it is never deducted from the prize
📌 Paid-entry challenges: 20% platform fee; the creator fee is paid from that 20%, never deducted from winners' shares. 80% of the pool goes to winners

Accuracy pool
rank 6+ within ±1%, split equally
📌 Distributable pool = prize pool − 20% platform fee (the creator fee is paid from that 20%, not added on top)
📌 2nd–5th place ranked pool split: 40% / 30% / 20% / 10% of the 25% ranked share
📌 Accuracy pool: entries ranked 6th and beyond whose error is within the accuracy band share the 15% pool equally (rank 1–5 do not share it, even if within the band)
📌 If nobody qualifies for the accuracy pool, the 15% share goes to 1st place (the closest predictor)
📌 Rounding: every share is rounded down to the cent; the leftover cents (always fewer than the winners) go one each to the shares with the largest fraction, and on a tie to the earlier entry — nothing is lost or stranded
📌 Requires 5+ participants for the full structure. With fewer entries a simpler split applies (1 entry: 100%; 2: 80/20; 3: 70/20/10; 4: 65/20/10/5)
📌 Only your best entry counts — if you enter the same challenge more than once, only your most accurate entry is eligible for a prize; your additional entries receive nothing
📌 Sponsor-funded prizes are paid from the sponsor's deposit; coin challenge prizes are the sum of coin entries
📌 Payouts processed within 7 business days of result confirmation via Stripe
Worked example
A sponsor-funded challenge with a €100.00 prize pool, 8 entrants, and 3 entrants within the accuracy band. No platform fee — 100% goes to winners.
Checks: €60.00 + €25.00 (2nd–5th) + €15.00 (accuracy) = €100.00 distributable — nothing created or lost. If nobody had been within the band, the €15.00 would go to 1st place instead (€75.00). The accuracy band is ±1% by default; a challenge may specify a different band.
