In a nutshell: Why is Pump.fun dropping today? PUMP is falling mainly because a widely covered Bitquery investigation into Solana sandwich bots—reporting that ~96% of detected attacks hit Pump.fun’s launch curve or PumpSwap—hit sentiment amid a mild altcoin risk-off tape, not because Bitcoin crashed. At about 12:39 a.m. ET (4:39 a.m. UTC / 9:39 a.m. PKT) on October 13, 2026, PUMP traded around $0.00507, down roughly 13.3% in 24 hours, per CoinGecko.

Why Is Pump.fun Dropping Today?
The short answer to why is Pump.fun dropping today is coin-specific reputational pressure after Bitquery’s Solana sandwich-bot study, amplified by softer Solana and memecoin risk appetite—not a wholesale Bitcoin crash. At our check, Pump.fun ranked about #47 by market value (roughly $2.35 billion), with a 24-hour high near $0.00602, low near $0.00479, volume around $239 million, and price near $0.00507, per CoinGecko.
Bitcoin sat near $83,430 (about −0.4% on the day at our check), Ether near $2,515 (about −1.6%), and Solana near $108 (about −3.8%), so PUMP underperformed the majors by a wide margin (CoinGecko). That gap points to Pump.fun-specific selling after the sandwich-bot headlines, not a quiet BTC-only session.
Main Reason: Bitquery Sandwich-Bot Study Hits Pump.fun Sentiment
Bitquery’s investigation into Solana sandwich attacks (widely covered October 12) estimates bots extracted about $29.7 million gross before costs over roughly 11 months (October 30, 2025–October 7, 2026). The study counts 6,850,144 attacks by 2,545 bot wallets affecting 2,154,994 wallets, and finds that about 96% of detected attacks hit Pump.fun’s launch curve or PumpSwap.
CryptoSlate summarized those Bitquery figures for a broader audience on October 12. CoinMarketCap’s Top Story attributes PUMP’s roughly 9–11%+ slide mainly to this study’s sentiment impact amid mild altcoin risk-off. CMC AI’s Pump.fun price analysis likewise frames the move around that reputational hit rather than a single exchange outage.
Sandwich attacks are a form of MEV (maximal extractable value) where a bot trades around a victim’s swap to capture price impact. That is adjacent to how crypto arbitrage works in practice—latency and ordering matter—but sandwiching is adversarial extraction from retail flow, not a neutral price-gap trade. For how decentralized venues fit into that stack, see our what is DeFi guide.
Important context: Bitquery’s numbers are an on-chain investigation estimate (gross before costs). They are not a court finding, a platform admission of new theft, or proof that every Pump.fun user was attacked—coverage ties the price reaction to sentiment and reputation, not to a fresh protocol exploit announced today.
Other Factors Behind the PUMP Drop
- Solana / memecoin risk-off. SOL was about −3.8% at our check while BTC was only about −0.4% (CoinGecko). Pump.fun tokens often trade as high-beta Solana memecoin proxies, so a softer SOL tape can amplify selling once a negative headline lands.
- High turnover after the headline. At our check, 24-hour volume near $239 million against a ~$2.35 billion market cap (CoinGecko) shows enough liquidity for large sellers to move price quickly once the sandwich-bot story spread.
- Mild broad altcoin caution. CMC’s Top Story frames the slide as study-driven sentiment plus mild altcoin risk-off—not a Bitcoin crash. ETH’s ~−1.6% day print fits that quieter majors backdrop with selective alt weakness.
What Happens Next
- Bitquery follow-ups: Watch whether Bitquery publishes updates, methodology notes, or platform-specific follow-ons to the sandwich-attacks investigation—calendar and research facts, not a price call.
- Platform / ecosystem response: Track any public statements from Pump.fun, Solana ecosystem teams, or major venues about MEV mitigations or launch-curve protections—only if they are published; do not invent responses.
- Live tape: PUMP’s 24-hour high (~$0.00602 at our check), low (~$0.00479), volume, and rank on CoinGecko show how far the washout already ran versus BTC’s quieter day print.
These are reported figures and watch-items, not price predictions.
FAQ
Did Pump.fun get hacked today?
No evidence in the cited coverage of a fresh Pump.fun protocol hack on October 13. The main catalyst is Bitquery’s sandwich-bot investigation and the sentiment reaction to those estimates (Bitquery; CryptoSlate; CMC Top Story).
Why did PUMP fall more than Bitcoin?
PUMP is a high-beta Solana memecoin-platform token. At our check it was about −13.3% while BTC was roughly −0.4% and SOL about −3.8% (CoinGecko)—classic underperformance when a coin-specific reputation headline hits amid softer SOL/memecoin risk appetite.
What is a sandwich attack?
A sandwich attack is an MEV strategy where a bot places trades before and after a user’s swap to capture price impact. Bitquery estimates ~$29.7M gross before costs over ~11 months on Solana, with ~96% of detected attacks tied to Pump.fun’s launch curve or PumpSwap—see Bitquery and CryptoSlate for the full methodology and caveats.
