RED-PUMP-2026-v1: A public benchmark of 860,213 pump.fun token launches with survival outcomes (May–June 2026 regime)

v1.3 (2026-08-11). Corrigendum: coverage-window relabeling. An independent external audit received 2026-08-11 identified that the collector polled a top-50-newest REST endpoint on pump.fun's public API. At the observed launch rate of ~18.08 new mints per minute during the observation window, the top-50 buffer gave each mint an effective visibility of only ~2.77 minutes before newer mints displaced it. The v1 headline "24-hour pooled graduation rate = 0.198%" is therefore a ≤6-minute fast-regime rate and a lower bound on the true 24-hour rate, not an estimate. A ceiling-crossing sensitivity analysis (initial_market_cap_sol ≤ 40, final_market_cap_sol > 165.41 SOL) recovers 1,126 additional graduating mints, raising the lower-bound pooled rate to 0.333%. Feature-level effects have been re-analysed for direction-dependent bias (see corrigendum §4): has_telegram (8.94×) and the initial-market-cap-quartile effect survive as lower bounds; has_website survives unchanged; has_twitter and sum_social_flags ≥ 2 become upper bounds. Cox model concordance is 0.858 (95% bootstrap CI [0.850, 0.870]) and drops to 0.794 under the ceiling-crossing stress test. The paper's Cox discrimination therefore reflects fast-regime observation until a v2 recollection permits refitting. Raw data files (red_pump_2026_v1_launches.jsonl.gz, red_pump_2026_v1_outcomes.csv.gz) are unchanged in v1.3. Every graduation, timeout, and timestamp in the deposit reflects what the observer actually saw. See CORRIGENDUM_v1.3_2026-08-11.pdf and KNOWN_LIMITATIONS.md for full detail. A v2 dataset re-collected via a Helius bonding-curve program subscription (which eliminates the visibility window entirely) is planned within 4 to 6 weeks of this corrigendum. Dataset. RED-PUMP-2026-v1 is a public benchmark of 860,213 Solana pump.fun token launches observed continuously between 2026-05-08 and 2026-06-10 (34 days). Of these, 832,941 unique mints reached a terminal outcome within the observer's 24-hour observation window: 1,651 graduated to PumpSwap (or to Raydium for tokens preceding the PumpSwap migration) and 831,290 timed out. The pooled rate is 0.198% (Wilson 95% CI [0.189%, 0.208%]); the steady-state rate excluding a four-day tracker warm-up window and the partial last day is 0.207% (Wilson 95% CI [0.198%, 0.218%]). Both rates apply the v1.3 coverage-window relabeling above. Fields. Each launch record contains the Solana mint address, observer detection timestamp, on-chain creation timestamp, initial market capitalisation in SOL, three Boolean indicators for advertised social channels (Twitter/X, website, Telegram), and the description-character length. Each terminal-outcome record contains the outcome class, minutes-to-outcome, and the detection lag. Companion paper. Released alongside a companion preprint titled "Pump.fun Graduation Regime Windows: Survival Analysis of 832,941 Token Launches and the Social-Presence Effect" (SSRN 6915560; arXiv:2607.02823). The companion paper reports Kaplan-Meier and Cox proportional-hazards results stratified by social-channel presence and initial market-capitalisation quartile. Key findings include an 8.94× graduation-rate lift for launches advertising a Telegram channel and a multivariate Cox concordance of 0.858 (see corrigendum §5 for the coverage-limit sensitivity). Schema and reproducibility. The schema is frozen as red-pump-1.0; future monthly versions (v2, v3, etc.) will preserve all v1 fields. Reproducible analysis code (Python 3.12, lifelines 0.30.3) is included in the deposit (km_full.py, km_figures.py). Version history.* v1.0 (2026-06-11): permanent original raw-data release.
