A 36-event arbitrage scan for August 28, 2026 flags SKR, HEMI, TAC, BTR, BLESS, MOVR and COLLECT running spreads of 5.8%–9.58% across Bitunix, Binance, Binance Futures, Gate Futures, Coinbase, Bybit, KuCoin and Exchange51. Full breakdown of top spreads, exchange-pair patterns, fee math and tomorrow's watchlist.
Thirty-six arbitrage events crossed the scanner today, and the top of the board belongs to SKR, which printed a 9.58% spread between Bitunix ($0.011228 bid-side) and Binance Futures ($0.012162). That is the kind of number that gets an arb desk's attention immediately — a single-digit-billion market cap token with a near double-digit dislocation between a tier-2 spot venue and a tier-1 futures order book. Behind it, HEMI ran 8.29% between Gate Futures and Bitunix, and TAC showed up three separate times in the top ten, which on its own tells you something about how thin and reactive that order book currently is.
The set skews heavily toward low-float, recently-listed alts — SKR, HEMI, TAC, BTR, BLESS, COLLECT — names where a handful of market makers haven't fully wired price feeds across every venue yet. MOVR is the one legacy mid-cap in the mix, and its 6.12% Bybit-to-Binance spread is a reminder that even established tokens can decouple hard during a volatility spike. Nothing here is a systemic risk-free bond-style arb; every spread on this board carries execution risk, and the desk take below is written with that lens throughout.
Sorting today's ten headline spreads by venue role produces a clear structural pattern. Binance Futures is the sell-side (premium) leg in four of the ten spreads — SKR ($0.012162), BTR ($0.159400), TAC ($0.003221), and COLLECT ($0.071440) — and only appears as a buy-side leg once (BLESS, $0.011874). That's a strong signal that Binance Futures perp pricing on these small-cap alts is running consistently hot relative to spot and futures books elsewhere, likely a function of retail long positioning and funding-driven premium rather than pure inefficiency. Any desk running a repeatable strategy here should treat 'short Binance Futures, long elsewhere' as the default posture on this basket, not the exception.
Bitunix is the most frequently-appearing venue overall — showing up on six of the ten spreads, split almost evenly between buy-side (SKR #1, TAC #1) and sell-side (HEMI, TAC #2, BLESS) roles. That inconsistency, rather than being noise, tells its own story: Bitunix doesn't have a systematic bias toward being cheap or expensive, it simply has laggy, asset-specific price discovery. That makes it a good venue to watch for arb opportunities in general, but a bad venue to build a directional 'always buy here' or 'always sell here' strategy around — each asset needs to be evaluated independently. Gate Futures shows a mild discount bias (buy-side in HEMI and BTR, sell-side only in TAC #1), and Exchange51 shows a clean and repeated discount bias, appearing as the buy-side leg in both of its appearances (TAC #2, COLLECT) — that consistency makes Exchange51 worth flagging as a venue to monitor specifically for buy-side entries on newer listings.
There's a real tradeoff on this board between the tier-1-to-tier-1 spreads (SKR #2 on Coinbase/Bybit, MOVR on Bybit/Binance) and the tier-2-involved spreads (anything touching Bitunix, Gate Futures, or Exchange51). The tier-1 pairs offer deeper books, meaning you can push more size before slippage erodes the edge, but they close fast — deep liquidity means other bots and desks are watching the same gap and competing for it, so windows on names like MOVR's 6.12% Bybit/Binance spread are typically measured in seconds to low minutes. The tier-2 pairs (SKR #1 on Bitunix, HEMI, both TAC prints involving Bitunix/Gate/Exchange51) can persist longer — sometimes tens of minutes on low-attention micro-caps — but the tradeoff is thin books: pushing more than a few thousand dollars through Bitunix or Exchange51 on a sub-cent token will move the price against you well before you capture the full quoted spread.
Position sizing recommendation: for the deep-liquidity pairs (SKR #2, MOVR), size to speed — smaller, pre-positioned orders that can fire the instant the alert triggers, since the spread itself won't survive slow execution regardless of size. For the thin-liquidity pairs (SKR #1, HEMI, both TAC legs, BLESS, COLLECT via Exchange51), size to depth — test the book with a small probe order first, confirm realized slippage against the quoted price, and scale in incrementally rather than firing a single large market order. A good rule of thumb on these micro-cap venues: assume your realized spread will run 1.5–3 percentage points below the quoted spread once slippage on both legs is accounted for, and size the trade so it's still profitable under that haircut.
Walking through the SKR #1 print as the worked example — buy Bitunix $0.011228, sell Binance Futures $0.012162, gross spread 9.58%. Assume standard taker fees: 0.10% on the Bitunix spot buy and 0.05% on the Binance Futures sell, for a combined 0.15% round-trip trading cost. That alone brings the position to roughly 9.43% before anything else. If this is executed as a pre-funded, already-positioned trade (inventory sitting on both exchanges, no live transfer required), net profit lands close to 9.2%–9.4% after accounting for minor execution slippage on Bitunix's thin book. If instead the trade requires an actual on-chain transfer of SKR from Bitunix to Binance Futures' linked spot wallet, add a withdrawal fee — typically a flat token amount rather than a percentage, but on a $0.011 token even a modest flat fee can represent 0.3%–1.0% of a small-size trade — plus the price-risk of holding an open, unhedged position for however long that transfer takes to confirm. That combination easily erases 1–2 percentage points of edge and introduces directional risk the pre-funded version doesn't have.
Withdrawal delays are the single biggest killer of paper profit on this board. Micro-cap tokens like SKR, HEMI, TAC, BTR, BLESS and COLLECT are exactly the category where exchanges impose longer withdrawal review times, manual compliance holds, or temporarily suspended withdrawals during periods of high volatility — precisely the moments when arb spreads are widest. Before committing real size to any Bitunix, Gate Futures or Exchange51 leg today, manually check the deposit/withdrawal status page for that specific asset; a suspended withdrawal window can trap capital on the wrong side of a trade for hours or days.
Low liquidity is the second major flag, and it applies to essentially every leg on this board that isn't Coinbase, Bybit, or Binance spot/futures. Quoted prices on thin order books represent the best bid or ask at a single instant — they are not a guarantee of fill quality for any meaningful size. Run a small test order first. Also watch for stale quotes: a price feed on a lower-tier venue that hasn't updated in the last few seconds can show a 'spread' that's actually just latency, not a real opportunity — this is a particularly live risk on Exchange51 and Bitunix given how often they anchor both sides of today's list. Finally, futures-involved legs (Gate Futures, Binance Futures) carry funding-rate and liquidation risk on top of the base spread — don't treat a futures leg as equivalent to a spot leg when sizing risk.
TAC is the name to watch first — three separate spreads across three different venue pairs (Bitunix/Gate Futures, Exchange51/Bitunix, KuCoin/Binance Futures) in a single session is not typical, and it suggests ongoing price-discovery lag across the board rather than a one-time event. Expect TAC to keep throwing spreads until market makers fully wire up cross-venue pricing. SKR is the second name to monitor closely given both its size (9.58%) and its appearance on two completely different venue pairs (Bitunix/Binance Futures and Coinbase/Bybit) — that breadth suggests genuine fragmentation in SKR price discovery rather than a single-venue glitch.
On venue pairs specifically: keep Binance Futures on the sell-side watchlist against Bitunix, Gate Futures and Exchange51 — today's pattern of Binance Futures running at a premium on smaller alts looks structural rather than incidental, and it's worth setting standing alerts on that specific pairing across the current basket. Exchange51 also deserves a dedicated discount-side watch given its clean, repeated buy-side role in both of its appearances today. In terms of timing, thin-liquidity dislocations on these tokens have tended to cluster around low-volume overnight hours (US late night / Asia pre-market) when market-maker coverage thins out — that's the window worth having alerts armed and capital pre-positioned for.
Thirty-six spreads, one clear structural bias toward Binance Futures running hot and Exchange51 running cheap, and a top print on SKR worth doing the fee math on properly before you chase it. Trade the books you can actually verify, size to the liquidity you can actually see, and don't let a headline percentage substitute for a real order-book check. Arbitrage Hunter — August 28, 2026.
