Bybit, the world’s second-largest cryptocurrency exchange by trading volume, on July 16, 2026 released an internal Q1 2026 analysis claiming its Rapid Price Improvement mechanism cut BTC spot slippage below two unnamed rivals. The figures are Bybit’s own, the rivals anonymized and unverifiable.
Key Takeaways
- Bybit reported average BTC spot slippage of 0.01 basis points on simulated $10,000 orders, against 0.02 and 0.07 at two rivals.
- The comparison exchanges are unnamed, and Bybit published no methodology, so no outside party can reproduce the numbers.
- Rapid Price Improvement matches eligible orders against a pool of liquidity providers quoting inside the visible bid-ask spread.
- Bybit’s own documentation limits the mechanism to non-algorithmic users, excluding the API-routed flow most institutions trade through.
- Bybit said its BTC/USDT book averaged $10.4 million of executable depth within a 5 basis point spread last quarter.
What Happened?
Bybit, which describes itself as the world’s second-largest cryptocurrency exchange by trading volume, published a Q1 2026 analysis of BTC spot execution and said its Rapid Price Improvement (RPI) mechanism produced lower slippage than two competitors it declined to name.
The study covers simulated BTC/USDT trades from $10,000 to $1 million. Bybit said the execution advantage held across that full range.
| Order Size (US$) | Bybit | Exchange A | Exchange B |
|---|---|---|---|
| 10,000 | 0.01 | 0.02 | 0.07 |
| 100,000 | 0.10 | 0.49 | 0.62 |
| 1,000,000 | 1.02 | 2.35 | 4.15 |

Sean Ballard, Head of Derivatives and Institutional Business, Trading Risk at Bybit said:
The numbers are Bybit’s own
Every figure in the study comes from Bybit’s internal execution analysis, and the two benchmark venues appear only as Exchange A and Exchange B. Bybit has not released its sampling period, its trade construction, or the unrounded values behind its headline claims.
That gap matters most where Bybit converts the raw slippage figures into percentages. The release describes the $10,000 gaps as roughly 52% and 84% reductions, yet the rounded table implies closer to 50% and 86%, and the precision needed to reconcile the two is not published.
Bybit’s broader argument is that third-party liquidity rankings, which read publicly displayed order books through standard APIs, understate the liquidity its price-improvement pool actually offers. The point is self serving, but not unreasonable. It is also impossible to test from outside the exchange.
How Rapid Price Improvement works?
Rapid Price Improvement is modeled on the retail price improvement frameworks used in traditional equity markets. Eligible spot orders match against a dedicated pool of liquidity providers quoting inside the public bid ask spread, so a fill can land at a better price than the visible order book shows.
The mechanism is narrower than the “retail through institutional” framing suggests. Bybit’s own documentation states RPI orders:
- Are post-only and match only with non-algorithmic users.
- Do not execute against orders submitted through OpenAPI.
- Can be placed only by selected market-making partners.
That design excludes API-routed institutional and algorithmic flow by construction, which is precisely the segment a block-size execution claim would need to cover. Bybit says traders can view the pool through an RPI order book API, even though its documentation describes RPI orders as excluded from the standard API order book.
Liquidity depth and the February backstory
Bybit reported that its BTC/USDT market averaged $10.4 million of executable depth within a 5 basis point spread during the quarter, against $5.4 million and $1.9 million at the two rivals. At 10 basis points, it put the figures at $15.1 million versus $11.4 million and $3.6 million.
RPI has carried this weight for Bybit before. Analytics firm Block Scholes found RPI orders accounted for over half of relevant liquidity by late March 2025, after the February 2025 security breach that drained the exchange’s books. The mechanism launched on February 24, 2025, days into that recovery.
Traders weighing venues on execution can pull the RPI order book through the public API and measure their own fills before trusting a vendor study.
CoinLaw’s Takeaway
The study reads as a marketing document with real data underneath it. The slippage and depth figures point in a consistent direction, and the mechanism behind them, matching orders inside the spread, is a recognized way to lower execution cost. What the release cannot supply is independence. Anonymized competitors, an unpublished method, and percentages that do not reconcile with the printed table leave the comparison resting entirely on Bybit’s word.
The tension worth holding is between the framing and the design. Bybit sells RPI as an advantage spanning retail orders through institutional blocks, while its documentation walls the pool off from the algorithmic and API-routed flow that institutions actually use. For a reader, the durable fact is structural. The 0.01 basis point figure came out of a curated, inside-spread pool that Bybit controls and outside analysts cannot yet audit.
