Exchange Flows Report — Week 34: Bybit Tops $1.68B as Sell-Side Pressure Grips the Market

Week 34 tracked 1,023 core flow events, with a combined 1,667 venue-level flags across ten exchanges moving $6,938.8M. Bybit's $1,679.5M led all venues on volume while Binance Futures led on event count (335); sell pressure ($3,816.4M) ran 45.4% ahead of buy pressure ($2,623.8M), even as pump volume ($477.0M) edged out dump volume ($418.8M).

📊 Exchange Flows Report — Week 34

Week 34 closed with 1,023 core flow events recorded across the tracked venue set, but the real headline sits one layer down: when every buy-pressure, sell-pressure, pump, and dump flag is added up venue-by-venue, the combined tally reaches 1,667 events across ten exchanges moving a combined $6,938.8M in flagged volume. Bybit was the single largest pool of that volume at $1,679.5M — 24.2% of everything tracked this week — even though it didn't log the most individual events. That distinction goes to Binance Futures, which fired 335 events (20.1% of the week's combined count) on $1,102.1M in volume. The gap between 'most active' and 'most volume' is the story of Week 34: a week where a small number of venues moved outsized size, and where the market's aggressive order flow leaned sell over buy by a wide enough margin to matter.

The macro backdrop reinforces that lean. Total sell pressure across the tracked market came in at $3,816.4M against $2,623.8M of buy pressure — sell-side flow ran 45.4% hotter than buy-side, a $1,192.6M gap that points to net distribution rather than accumulation this week. Yet the pump/dump split tells a slightly different story: total pump volume ($477.0M) actually edged out total dump volume ($418.8M) by $58.2M, a roughly 53/47 split in favor of pump-driven candles. Read together, the two metrics describe a market where price action skewed marginally toward upside pumps, but where the underlying aggressive flow behind those moves skewed toward sellers — the kind of divergence that shows up when rallies get sold into rather than chased, and dumps happen fast and thin rather than grinding lower. That's the structural lens for everything below: which venues carried the size, where the DEX/CEX split sat, and what to flag heading into Week 35.

🏆 Exchange Leaderboard

Ranked by combined activity, Week 34 was topped by Binance Futures on raw event count and by Bybit on raw size. Shares below are computed against the 1,667-event / $6,938.8M combined base recorded at the exchange level this week (not the 1,023 headline figure), since flow flags — buy pressure, sell pressure, pump, dump — are tallied per venue and a single move can trip more than one flag.

Three things stand out. First, Bybit converted fewer events than Binance Futures into far more volume — its average print size ($5.71M) is nearly double Binance Futures' ($3.29M), consistent with Bybit carrying a heavier share of large-ticket derivatives flow this week. Second, Hyperliquid's $9.64M average event size isn't just the largest on the board — it's more than 2.5x the blended CEX average of roughly $3.74M per event, and it got there with the fewest events of any top-tier venue (more on that below). Third, KuCoin and Exchange28 sit in a different tier entirely: mid-pack event counts but volume an order of magnitude smaller, pointing to retail-sized, high-frequency flow rather than size-driven activity. On week-over-week movement: this report doesn't carry a Week 33 leaderboard to diff against, so rather than guess at share deltas, treat this ranking as the new baseline and watch whether Bybit's volume lead and Hyperliquid's ticket-size lead hold into Week 35.

🔍 Top 3 Exchange Deep Dives

Binance Futures

Binance Futures led the board on raw activity — 335 events, the most of any venue tracked this week — on $1,102.1M in volume, an average ticket of $3.29M. That combination (highest event count, third-highest volume) is the signature of a high-frequency, breadth-driven derivatives book: as the largest perpetuals venue by open interest globally, Binance Futures typically sees flow concentrated in BTC and ETH perpetuals alongside a long tail of higher-beta altcoin pairs, and a $3.29M average ticket is consistent with a mix of programmatic and mid-size discretionary flow rather than a handful of block trades. This dataset doesn't break out per-pair volume, so exact top pairs can't be confirmed here, but the event-to-volume ratio points to breadth over concentration. On direction: the market-wide split this week was roughly 59% sell-pressure vs 41% buy-pressure ($3,816.4M vs $2,623.8M combined), and given Binance Futures' status as the single largest event-count contributor, it's a reasonable venue to look to first for where that sell-side flow concentrated — though buy/sell pressure isn't split per exchange in this dataset, so that's a directional read, not a confirmed number.

Bybit

Bybit carried the week's single largest volume pool — $1,679.5M, or 24.2% of everything flagged across the ten tracked venues — on 294 events, for an average ticket of $5.71M. That's the second-largest average print size of any CEX in the dataset, behind only OKX's $5.97M, and it means Bybit did more with less: 41 fewer events than Binance Futures but $577.4M more volume. That combination — high average ticket, strong event count, largest total pool — is consistent with Bybit's derivatives book skewing toward larger, more deliberate positioning this week rather than high-frequency small-ticket flow. As with Binance Futures, per-venue buy/sell splits aren't broken out here, so the direction of that flow can't be confirmed from this data alone — but given Bybit's outsized share of total volume, it's the venue most capable of moving the market-wide sell/buy ratio on its own.

Bitget

Bitget rounded out the top three with 205 events and $960.2M in volume — 12.3% of activity and 13.8% of volume — at a $4.68M average ticket, squarely between Binance Futures' $3.29M and Bybit's $5.71M. Bitget's profile this week reads as the most centrist of the top three: none of its metrics are the extreme in either direction, which is itself worth noting after periods where campaign-driven or copy-trading flow has pushed Bitget's numbers toward one tail or the other. No standout single-event anomaly is visible at this level of aggregation, which for a venue this size is a mildly notable 'quiet strength' data point — consistent, broad-based volume rather than a spike.

⚡ CEX vs DEX Analysis

Hyperliquid is the only DEX in this week's tracked set, and it punched well above its event count. 119 events — the fewest of any top-tier venue, just 7.1% of the combined 1,667-event tally — produced $1,147.0M in volume, or 16.5% of the week's total flow. That's a $9.64M average ticket, more than 2.5x the blended CEX average of roughly $3.74M (calculated from the remaining $5,791.8M across 1,548 CEX events). Put differently: Hyperliquid needed roughly one event for every 13 CEX events to move a comparable share of total volume.

That gap is the clearest structural signal in this week's data. On-chain perpetuals flow, by construction, tends toward larger, more deliberate positions — gas costs, on-chain slippage, and self-custody requirements filter out the smallest retail tickets that inflate CEX event counts (see KuCoin's $0.41M average and Exchange28's $0.49M average at the other extreme). Hyperliquid's $1,147.0M this week outright beat five of the nine CEXs on volume — Bitget, Binance, OKX, Bitunix, and Gate Futures all did less size — despite logging fewer events than every one of them. That's not 'volume migrating to DEX'; combined CEX volume ($5,791.8M) still dwarfs Hyperliquid more than 5-to-1. It's better read as a composition signal: the flow that does route through Hyperliquid is disproportionately large-ticket — the footprint of institutional-style positioning — while CEX volume remains the broader, more retail-inclusive base, with a size distribution stretching from $0.41M (KuCoin) up to $5.97M (OKX) average tickets.

🌏 Regional Flow Patterns

The regional read on Week 34 starts with an absence: none of the ten tracked venues this week are U.S.-domiciled, dollar-regulated spot exchanges. Coinbase and Kraken — the usual reference points for 'Western' flow — recorded zero events in this tracking set. Every venue with meaningful volume this week (Binance Futures, Bybit, Bitget, Binance, OKX, Bitunix, Gate Futures, KuCoin) is either headquartered in or primarily serves Asia-Pacific and offshore-derivatives markets, plus Hyperliquid as the sole DEX. That's a structural fact about this week's dataset, not a claim that Western flow went to zero market-wide — but it does mean this report's $6,938.8M in tracked volume is, by composition, an offshore-derivatives-and-DEX picture rather than a U.S.-regulated-spot one.

Within that offshore-heavy set, Bybit, OKX, and Bitget — the three venues most associated with Asian and Southeast Asian retail and professional derivatives desks — combined for $3,474.4M in volume across 639 events, exactly half of the week's total volume base. Binance's global, dual spot-and-futures footprint (Binance Futures at $1,102.1M plus Binance spot at $242.2M, $1,344.3M combined across 481 events) adds another 19.4% on top of that. Timezone-level attribution isn't available in this dataset — no per-event timestamps are broken out here — so specific Asia-session versus U.S.-session patterns can't be confirmed from these numbers alone. But the venue mix itself is the clearest regional signal: this was a week where offshore derivatives desks and one DEX did essentially all the tracked work.

One data-quality flag worth carrying forward: Exchange28 appears in this tracking set without a resolved display name, echoing prior mapping gaps seen with newly onboarded venues. At 83 events and $40.5M, its volume is too small to move any headline number, but its regional classification can't be confirmed until it's mapped to a named venue.

💰 Arbitrage Routes Analysis

This dataset doesn't carry live order-book or cross-exchange price-spread data, so exact basis-point spreads for Week 34 can't be quoted with confidence — any specific spread figure here would be manufactured, not measured. What the flow data does support is a structural read on which routes are best positioned to carry arbitrage size, based on where liquidity and average ticket size concentrated this week.

Execution insight for the week: venues with the smallest average tickets — KuCoin ($0.41M) and Exchange28 ($0.49M) — are the least attractive arbitrage legs of the group. Thin average size per event usually means thinner book depth at the top, so routes anchored on either would need to be sized down considerably to avoid moving the market against the trade.

📈 Market Share Shifts

Without a Week 33 exchange-level snapshot to diff against, this report can't responsibly claim confirmed share deltas — better to flag that directly than fabricate a 'gained X points, lost Y points' narrative. What Week 34 does establish is a clean baseline: Bybit holds the largest single share of tracked volume at 24.2%, Hyperliquid holds 16.5% on the back of its outsized average ticket size, and Binance Futures holds the largest share of event count at 20.1% despite sitting third on volume.

The long-term implication worth tracking is the volume-vs-events divergence itself. If Bybit continues converting fewer events into more volume than Binance Futures — as it did this week by a $577.4M margin on 41 fewer events — that's a share-of-size trend distinct from a share-of-activity trend, and the two can move in opposite directions. Similarly, if Hyperliquid's average ticket size ($9.64M this week) holds or grows relative to the CEX blended average ($3.74M), that's the metric to watch for any genuine shift toward on-chain settlement of larger positions, rather than raw Hyperliquid event count, which is likely to stay structurally lower than any major CEX simply due to on-chain transaction costs.

🔮 Next Week Watch

Sign Off

Week 34 was a week of concentration: two venues, Bybit and Hyperliquid, combined for over 40% of tracked volume on barely a quarter of tracked events, while the market's aggressive order flow leaned sell over buy by more than $1.19B — even as pump volume nudged out dump volume. Structure over noise. That's where the money actually moved this week, and it's the lens worth carrying into Week 35.
