Binance Pool Shuts Down: Bitcoin Mining Concentration & What It Means for BTC

 

Binance published its notice on the closure of Binance Pool services on October 13, confirming that the pool and its related products stop at 07:00 UTC on November 10, 2026. At that moment mining connections are severed and endpoints stop accepting submissions, with any hashrate or shares sent afterwards neither processed nor credited. The closure covers more than the pool itself, taking in Pool Savings, Cloud Mining, the Transaction Accelerator, Telegram hashrate alerts, email notifications and the mining API.

 

Read as a product decision, this is one exchange retiring a line of business. Read against the distribution of hashrate, it marks something else. According to CoinDesk's report, Binance Pool ran roughly 26 EH/s last December, about 2.3% of the network, and now accounts for about 9.2 EH/s, under 1% and eleventh in the rankings, a decline of roughly 65%. The same report notes that Foundry USA, AntPool and F2Pool together now hold about 64.2% of network hashrate, against 61.4% for the top three last December, when ViaBTC rather than F2Pool held third place. When a pool exits, its remaining hashrate tends to land with operators that are already large, and that is what makes this notice worth reading closely.

 

 

 

Three deadlines govern everything. The pool stops and disconnects miners at 07:00 UTC on November 10, any identity verification needed to collect remaining rewards must be completed by 23:59 UTC that same day, and the pool pages become permanently inaccessible at 07:00 UTC on November 24.

 

The hashrate left before the decision did. Falling from roughly 26 EH/s to about 9.2 EH/s pushed Binance Pool out of the top tier well before the announcement, which cites only an ongoing review of products and services and gives no financial reason.

 

The top three now sit close to two thirds. Hashrate Index pool data shows Foundry USA at roughly 261.6 EH/s for 24.98%, AntPool at 221.4 EH/s for 21.14% and F2Pool at 176.4 EH/s for 16.84%, against total network hashrate of about 1,013 EH/s.

 

What concentrates is block template authority, not just hashrate. Under the prevailing Stratum V1 model, the pool decides which transactions enter a block, while the hashrate itself belongs to miners who can redirect it at will.

 

This exit is not an isolated case. CoinDesk also notes that SBI Crypto closed its pool on July 31, OKX ended pool services in February 2024, and Poolin, once close to a fifth of global hashrate, filed for bankruptcy in July owing about $173 million.

 

The migration window is under four weeks. Miners must repoint machines before November 10 or their hashrate hits a dead endpoint, which is economically identical to switching the machines off.

 

 

 

The hard boundary is 07:00 UTC on November 10. Mining connections are cut, Stratum addresses and endpoints go dark, and submissions after that moment are not accepted, processed or credited. Shares submitted before it still count toward the final reward calculation under Binance Pool rules.

 

The second date is 23:59 UTC the same day. Any account that needs identity verification or similar steps in order to receive outstanding rewards, refunds or settlements must complete them by then. The notice adds that eligible balances are processed after the cutoff subject to product rules, account status, risk controls and compliance checks, and that no new rewards or benefits accrue past that point.

 

The third date is 07:00 UTC on November 24. Pool pages remain viewable for fourteen days after closure and then disappear for good. For miners, that fortnight is the only window to export statements, hashrate curves and settlement records, which means accounting and tax documentation has to be finished inside it.

 

Pool Savings carries one separate obligation. Positions must be actively unsubscribed or redeemed before the service ends rather than left to resolve themselves.

 

 

Binance Pool launched in April 2020 and ran for about six years. Citing Hashrate Index, CoinDesk notes it ranked ninth last December with roughly 26 EH/s and 2.3% of the network, against about 9.2 EH/s and under 1% in the latest table.

 

That decline happened against violent swings in total hashrate. TokenPost's tally traces the network from a peak near 1,160 EH/s in October 2025 down to roughly 850 EH/s by February 2026, a drop of about 27%, followed by a recovery that reached an estimated 1,075.4 EH/s on October 13. Miner economics were severely squeezed through that stretch, with hashprice hitting a record low of $27.70 per PH/s per day in June 2026. By early October, industry data compiled by MillionMiner put hashprice back near $40 per PH/s per day, with September miner revenue of $1.12 billion, about 34% above the June trough.

 

In that environment, sensitivity to settlement reliability, fees and withdrawal thresholds rises sharply, and hashrate migrates toward the largest operators faster. Binance Pool did not lose hashrate because it announced a closure. The hashrate left first, and the closure confirmed the outcome. To test where a given machine breaks even at current difficulty and price, the bitcoin mining profitability calculator is the practical tool.

 

 

 

Binance Pool ran full pay-per-share. As Spark's definition of FPPS sets out, the pool pays a fixed rate per valid share, derived from the current block subsidy plus average transaction fees across roughly the last 144 blocks with outliers stripped, divided by network difficulty, and it pays whether or not the pool finds a block in that period.

 

The point of the design is risk transfer. Under PPLNS, miners are paid only when the pool finds a block and split the actual subsidy and actual fees, so income tracks luck. FPPS hands both block-finding variance and fee volatility to the operator, giving miners something close to a daily wage in exchange for a fee of typically 2% to 4%, against 0% to 2% for PPLNS, and for giving up the upside during fee spikes.

 

That also explains why FPPS is close to standard among large pools. It requires reserves deep enough to cover extended unlucky runs, which is a balance sheet requirement rather than a technical one, and smaller operators struggle to match the same settlement experience. How fee revenue is trending within miner income can be followed through the bitcoin fee tracker guide.

 

 

One distinction gets lost in most coverage. Miners own machines and power, which is to say the hashrate itself, and pools hold none of it. Under Stratum V1, in use since 2012, miners receive a template from the pool, and the pool decides which transactions go in, in what order, and where the coinbase pays. Spark's research on block template construction describes the arrangement as one in which the entity performing the work and the entity deciding what the work commits to are completely separated.

 

So when the top three pools are said to control 60% of hashrate, the precise statement is that transaction selection for 60% of blocks sits with three operators, while ownership of that hashrate is spread across thousands of miners worldwide. The risk implications of the two readings are not the same. For why delayed or excluded transactions matter at the protocol level, the explainer on how bitcoin UTXOs work is the right starting point.

 

 

 

The latest Hashrate Index table shows Foundry USA at 24.98%, AntPool at 21.14% and F2Pool at 16.84%, close to 63% between them, with ViaBTC fourth at 11.13% taking the top four above 74%. mempool.space's weekly view is consistent, with Foundry USA at 25.35%, AntPool at 21.49%, F2Pool at 17.15% and ViaBTC at 10.18%, at a difficulty of 132.72T.

 

The number worth noting is that the top two alone are close to 47%. CoinDesk estimates that if all of Binance Pool's remaining hashrate moved to the top three, their combined share would rise to about 65%, assuming nothing else changes.

 

 

This is not purely theoretical. Bitcoin.com reported a rare two-block reorganization on March 23, 2026 around height 941880, in which Foundry USA competed against a branch backed by AntPool and ViaBTC, and the chain extended by the larger operator prevailed while the losing branch's blocks were removed and their transactions returned to the mempool. In a race, a larger share of hashrate is a structural advantage, which is concentration expressing itself at the consensus layer.

 

Transaction filtering is the other channel. The Spark research documents two cases: Marathon's compliance-oriented pool in May 2021, where block 682,170 carried only 178 transactions and roughly $2,903 in fees against about $17,500 in neighbouring blocks, and a series of F2Pool blocks between late 2023 and early 2025 in which specific transactions appeared to be filtered. Those transactions eventually confirmed in blocks from other pools, so the effect was delay rather than permanent exclusion, though delay alone undermines protocols that depend on timely settlement. Mining Pool Observer tracks exactly this, comparing node-generated templates against the blocks pools actually publish and listing missing and sanctioned transactions separately.

 

 

The fix being pursued is to return template construction to miners. Stratum V2 and its Job Declaration component let a miner run its own node, build a template and propose it to the pool, alongside lower job latency and mandatory encryption at the protocol level. OCEAN takes a different route with DATUM, where miners build templates from their own mempool through a gateway and receive coinbase payouts directly.

 

Progress is real but early. Per Spark's research, seven pools representing roughly 75% of hashrate joined the Stratum V2 Working Group in May 2026, and block 955,318 on June 25 became the first known production block built from a miner's own template under Job Declaration, yet miner-constructed templates remain under 3% of all blocks. The structural answer exists. It has not yet changed the structure.

 

 

The migration itself is straightforward. What goes wrong is leaving it to the final day. Registration and verification at a new pool come first, and both can queue during a rush. Next, every Stratum address in the miners or firmware has to be replaced, including backup entries, because keeping the old endpoint as a fallback achieves nothing once it is switched off. Third comes a check on the new pool's payout model, fee, minimum withdrawal and settlement cycle, since FPPS and PPLNS produce visibly different cash flows and small operations in particular can find earnings stranded below a withdrawal threshold.

 

Two items are easy to miss. Pool Savings positions must be redeemed actively, and all statements and hashrate records need exporting before the pages close on November 24. Separately, Binance launched a $500 million lending programme for miners in October 2022, offering secured loans of 18 to 24 months at 5% to 10%, and CoinDesk notes the closure notice neither mentions that programme nor discloses any outstanding balance, so borrowers should confirm how their contracts will be handled.

 

On pool selection, defaulting to the largest operator is not automatically the best answer. Fees, payout model, server latency, withdrawal thresholds and transparency all carry weight, and given the current distribution, routing hashrate to a pool outside the top three has a more constructive marginal effect on network structure.

The risks stack in layers. The most immediate is operational: missing November 10 means hashrate spinning against nothing, and at roughly $40 per PH/s per day, the daily cost of a 200 TH/s machine is easy to quantify. Settlement risk follows, since verification, risk controls and account status all affect when final balances arrive. Structural risk comes next, because remaining hashrate flowing to the leaders pushes the top three closer to two thirds. Market risk sits underneath all of it, with bitcoin trading near $80,747 on October 15 and down 3.18% over 24 hours per the CoinDesk price page, since price feeds directly into hashprice and therefore into how miners choose.

 

In a dispersal scenario, the orphaned hashrate spreads across ViaBTC, MARA Pool, SpiderPool, Luxor and OCEAN, the top three hold near 63%, and the structure does not deteriorate. That requires mid-tier pools to compete hard on fees and settlement quality.

 

In a concentration scenario, miners prioritising settlement stability go straight to the largest operators, the top three advance toward 65% and the top two clear 50% between them. That is not a 51% attack, because the hashrate belongs to miners and can leave at any time, but authority over block composition tightens materially.

 

In a structural improvement scenario, Stratum V2 and DATUM adoption rises as new firmware ships, and even with hashrate still pooled under a few names, template construction disperses back to miners, which blunts what the concentration figures actually mean. That path depends on engineering timelines rather than on price.

 

Four indicators are worth tracking. The share held by the top three on Hashrate Index and mempool.space after November 10 answers the central question directly. Whether total hashrate holds above 1,000 EH/s shows how willing miners are to expand. The direction of the next difficulty adjustment, currently estimated by mempool.space at about plus 5.56%, matters for margins. And the share of blocks built from miner-constructed templates shows whether the technical fix is moving beyond single digits.

 

 

For James Mitchell, the signal in this notice is not that Binance is leaving but that it reveals how steep the economies of scale in pool operation have become. FPPS requires an operator to front the variance of block luck from its own balance sheet, which makes pool operation a capital business rather than a technical one. When hashprice hit a record low of $27.70 in June, the cost of fronting that variance and miners' appetite for guaranteed settlement rose at the same time, and hashrate inevitably gravitated to the operators with the deepest reserves. The slide from 2.3% to under 1% is that mechanism running its course. The shutdown simply ratifies the result.

 

Two misreadings look likely. The first equates a 64% share for three pools with a 51% attack risk. Ownership of the hashrate sits with miners, and one poor fee decision or one trust event can move it within days, which is the critical difference between a pool and a monopoly. The real exposure is not the share figure but authority over block templates, and what US-linked pools could be compelled to do under regulatory pressure. The second treats the wave of pool exits as industry contraction. Poolin's bankruptcy, OKX's withdrawal, SBI Crypto's closure and now Binance's shutdown are a shakeout in the service layer, which does not contradict total hashrate recovering from 850 EH/s to 1,075 EH/s. The machines and the power are still there. The access points are fewer.

 

Three numbers deserve attention from here. Whether the top three settle near 65% or hold around 63% after November 10 determines whether this migration improved or worsened the structure. Whether miner-constructed templates climb from under 3% toward double digits is the only hard measure of whether the technical remedy can dilute concentration risk. And whether hashprice holds above $40 decides if mid-tier pools have the margin to compete for hashrate that currently has nowhere settled to go.

 

The cross-asset pattern is a familiar infrastructure consolidation story: subsidies fade, margins compress, service providers exit and survivors gain pricing power. In traditional industries, that stage usually precedes either regulatory intervention or a new protocol standard. What makes bitcoin unusual is that its protocol layer offers a self-correcting exit, since Stratum V2 and DATUM allow hashrate to stay pooled under a handful of names while the authority that actually matters returns to miners. Whether that path succeeds is a more consequential question than any single pool closure.

 

 

 

Per Binance's October 13 notice, Binance Pool and related services stop at 07:00 UTC on November 10, 2026, when mining connections are cut and endpoints stop accepting submissions. Machines must be repointed to another pool before that moment. Users who need identity verification or similar steps to collect remaining rewards have until 23:59 UTC the same day, and the pool pages become permanently inaccessible at 07:00 UTC on November 24.

 

 

The machines keep running, but their work is submitted to a dead endpoint, recorded by no one and compensated at zero, which amounts to paying full electricity to produce nothing. The notice states plainly that hashrate and shares submitted after the cutoff will not be accepted, processed or credited, while shares submitted before it still count toward final rewards. At a hashprice near $40 per PH/s per day, the cost of each idle day converts into a specific figure.

 

 

The notice cites an ongoing review of its products and services and offers no financial explanation. The data suggests another angle. Citing Hashrate Index, CoinDesk reports Binance Pool fell from roughly 26 EH/s and 2.3% of the network last December to about 9.2 EH/s and under 1% now, a decline near 65% that dropped it to eleventh. At that scale, carrying the capital and operational burden of an FPPS pool becomes hard to justify commercially.

 

 

Full pay-per-share pays miners a fixed rate per valid share, covering the block subsidy plus average transaction fees from roughly the last 144 blocks, regardless of whether the pool finds a block. It transfers block luck and fee volatility from miner to operator, giving miners something close to a daily wage at a typical fee of 2% to 4%, while surrendering the upside during fee spikes. Absorbing that risk requires substantial reserves, which is itself a barrier to scale.

 

 

The equation does not hold directly. Hashrate belongs to miners, with pools acting only as connection points, and miners can redirect machines at any time, which separates a pool's share from genuine control. The more realistic exposure is authority over block templates, since under Stratum V1 the pool decides what goes into a block. Documented episodes of apparent transaction filtering, and the two-block reorganization triggered by pool competition in March 2026, are how that exposure has actually surfaced.

 

 

The decisive variables are payout model, fee, server latency, minimum withdrawal and settlement cycle. FPPS suits operations that need predictable cash flow, while PPLNS charges less but tracks luck. Smaller miners should pay particular attention to withdrawal thresholds, since earnings can sit stranded inside a pool for months. From a network perspective, connecting to a pool outside the top three contributes more to dispersal, and the gap in fees and experience is usually smaller than assumed.

 

 

They target the core of it, namely returning template construction to miners. Stratum V2's Job Declaration lets a miner run its own node, build a template and propose it to the pool, while OCEAN's DATUM lets miners build from their own mempool and receive coinbase payouts directly. The direction is right but adoption is early, with the first known production block from a miner-built template arriving in June 2026 and such blocks still under 3% of the total. Scaling depends on firmware and pool engineering rather than on market conditions.
