How Many Bitcoins Are There in 2026? Supply, Mined and Remaining Statistics

About 20,045,225 Bitcoins had been mined as of June 19, 2026, according to Blockchain.com on-chain data, against the 21,000,000 BTC that will ever exist. That works out to 95.45% of the maximum supply. The headline number sounds almost finished, yet that final million trickles out for more than another century. Three correct answers fit the question of how many bitcoins are there: the fixed cap, the mined total, and the usable float after lost coins, sized with Chainalysis research.

Key Takeaways

• Roughly 20,045,225 BTC had been mined as of June 19, 2026, at block height 954,593.
• That leaves about 954,775 BTC still to be issued before the 21,000,000 maximum supply is reached.
• The network has already produced 95.45% of all bitcoin that will ever exist.
• The block reward started at 50 BTC and halves every 210,000 blocks, which is why the total converges to exactly 21,000,000.
• The reward fell to 3.125 BTC at the April 2024 halving, and the final coin is projected to be mined around the year 2140.
• At the current reward, the network issues roughly 450 BTC of new supply per day, down from about 900 BTC before the 2024 halving.
• Chainalysis estimates that between 2.78 million and 3.79 million BTC are likely lost, around 17% to 23% of the supply.

How Many Bitcoins Are There Right Now?

About 20,045,225 bitcoins existed on the network as of June 19, 2026, at block height 954,593, according to Blockchain.com on-chain data. That total represents 95.45% of the 21,000,000 BTC hard cap fixed by the Bitcoin protocol. The mined supply is the running on-chain total, updated each time miners add a block to the Bitcoin network, so the precise figure ticks upward every ten minutes or so.

• About 20,045,225 BTC existed as of June 19, 2026, at block height 954,593, per Blockchain.com.
• That is 95.45% of the 21,000,000 BTC hard cap.
• Each new block adds 3.125 BTC to the total.
• Roughly 954,775 BTC remain to be mined.
• The supply is verifiable on any public blockchain explorer, not reported by a central issuer.

Each new block currently adds 3.125 BTC to that total. Anyone can verify the live number on a public blockchain explorer, since the supply is recorded on a transparent ledger rather than reported by a central issuer.

By the numbers: Blockchain.com on-chain data shows 20,045,225 BTC mined as of June 19, 2026, against a fixed cap of 21,000,000 BTC, with about 954,775 BTC still to come. That puts the network at 95.45% of its maximum supply.

How Many Bitcoins Are Left to Mine?

About 954,775 BTC remain to be issued before the network hits its 21,000,000 maximum supply, according to Blockchain.com on-chain data for June 2026. That is roughly the final 4.55% of all bitcoin. The counterintuitive part is the timing.

• About 954,775 BTC remain before the 21,000,000 cap, per Blockchain.com (June 2026).
• That is the final 4.55% of all bitcoin.
• The last coins take until around 2140 to mine.
• Issuance halves every 210,000 blocks, so the remaining coins arrive in ever-smaller increments.

Even though most of the supply already exists, the last sliver takes until around 2140 to mine because the Bitcoin protocol keeps halving the block reward every 210,000 blocks. Each halving cuts new issuance in half, so the remaining coins arrive in ever-smaller increments. The supply curve is steep early and nearly flat at the end, which is the Final Million paradox: most coins exist, yet the last million stretches across more than a hundred years.

Why Is Bitcoin Capped at 21 Million?

The 21,000,000 ceiling is not an arbitrary round number; it falls out of the reward schedule, where the block reward starts at 50 BTC and halves every 210,000 blocks. Add up that geometric series (210,000 blocks times 50 BTC, then 25, then 12.5, and so on) and the total converges on 21,000,000 BTC. The cap is a mathematical consequence of the issuance rules, not a separate setting someone can raise.

• The cap falls out of the reward schedule: 50 BTC halving every 210,000 blocks.
• The geometric series (50 + 25 + 12.5 and so on) converges to 21,000,000.
• One satoshi equals 0.00000001 BTC, so the cap is 2.1 quadrillion satoshis.
• Once the reward rounds below one satoshi, no new coins can be created.

Because the reward halves at fixed block intervals, the issuance is fully predictable years in advance. That predictability is the design feature behind the fixed-supply argument many of Bitcoin’s proponents make. For readers tracking how digital systems handle scarcity, the contrast with elastic money supplies is the whole point of the mechanism.

How the Halving Schedule Controls New Supply

The halving is the lever that controls Bitcoin’s supply: Every 210,000 blocks, about once every four years, the reward miners receive for each new block is cut in half. The schedule has already run through four halvings, each one slowing the pace of new coins entering circulation.

• The block reward halves every 210,000 blocks, about once every four years.
• Bitcoin launched at 50 BTC per block in 2009.
• The reward fell to 25 BTC in 2012, 12.5 BTC in 2016, and 6.25 BTC in 2020.
• It dropped to 3.125 BTC at the April 2024 halving, at block height 840,000.
• Four halvings have run so far, each slowing new-coin issuance.

The reward dropped to 25 BTC in 2012, 12.5 BTC in 2016, 6.25 BTC in 2020, and 3.125 BTC at the April 2024 halving at block height 840,000. Each step roughly halves the rate at which fresh supply reaches the market. The pattern repeats until the reward becomes too small to divide, which is the mechanism that eventually ends new issuance entirely.

When Will the Last Bitcoin Be Mined?

The final bitcoin is projected to be mined around the year 2140, once the block reward rounds below one satoshi and can no longer be halved. That date is an estimate rather than a fixed calendar event, because block times vary slightly around the ten-minute target. Still, the halving math makes the rough endpoint highly predictable.

• The final bitcoin is projected to be mined around 2140.
• That is when the reward rounds below one satoshi and can no longer halve.
• After that, no new bitcoin is created, and supply becomes truly fixed.
• Issuance has run since the first block in 2009.

After that point, no new bitcoin will be created, and the protocol will have issued every coin it ever can. The supply becomes truly fixed, ending the slow drip of new issuance that has run since the first block in 2009.

Mined Supply vs Usable Supply: The Lost-Coin Gap

The spendable supply is smaller than the mined supply, because Chainalysis on-chain analysis estimates that between 2.78 million and 3.79 million BTC are likely lost or permanently unrecoverable, around 17% to 23% of the supply. That makes “how many bitcoins are there” a question with three defensible answers: the 21 million cap, the roughly 20.05 million already mined, and the smaller float that can actually move once lost coins are netted out.

• Chainalysis estimates 2.78 million to 3.79 million BTC are likely lost or unrecoverable.
• That is roughly 17% to 23% of all supply.
• Many lost coins trace back to the network’s earliest years.
• Lost keys cannot be recovered, and the ledger cannot distinguish a lost coin from a held one.

The estimate is a modelled range rather than an exact count, since the public ledger cannot reliably distinguish a deliberately held coin from a truly lost one. Many of the suspected lost coins trace back to the network’s earliest years, when each one was worth only pennies and early adopters had little reason to safeguard the keys.

The mechanics of loss are mundane rather than dramatic. A private key written on a discarded hard drive, a wallet password forgotten, or coins held by an owner who died without sharing access all produce the same outcome: the coins still appear in the supply on-chain, but no one can ever move them again. Because the lost-coin range spans more than a million BTC between its low and high estimates, the true usable float is genuinely uncertain rather than a settled figure.

How Much New Bitcoin Enters Circulation Each Day

At the post-2024 reward of 3.125 BTC and roughly 144 blocks per day, the network now issues about 450 BTC of new supply daily, down from around 900 BTC per day before the April 2024 halving. The daily figure halves alongside the block reward at each halving, so the inflow of new coins shrinks geometrically over time even as the cap stays fixed.

• At 3.125 BTC per block and about 144 blocks per day, the network issues roughly 450 BTC daily.
• That is down from around 900 BTC per day before the April 2024 halving.
• Daily issuance halves alongside the block reward at each halving.
• Against 2.78 to 3.79 million likely-lost BTC, the spendable float grows slowly.

Each future halving cuts daily issuance in half again, so the rate of new supply entering circulation keeps falling geometrically even as the cap stays fixed. The usable float therefore grows more slowly than the raw mined total suggests. The same scarcity-by-design logic shows up across digital platforms that ration a fixed resource, much as Google search statistics track a capped attention pool.

Key data point: Chainalysis pegs likely-lost bitcoin at 2.78 million to 3.79 million BTC, a modelled range, not an exact count. Set against roughly 450 BTC of new daily issuance, the figures suggest the spendable float expands far more slowly than the headline mined total implies.

What Happens to Miners After 21 Million Bitcoin?

Once issuance ends around 2140, miners will no longer receive new bitcoin and will be paid entirely through transaction fees. The fee market becomes the sole incentive for securing the network, replacing the block reward that funds mining today. How robust that fee revenue will be is an open design question, since it depends on transaction demand more than a century out.

• After issuance ends around 2140, miners earn only transaction fees.
• The fee market replaces the block reward as the security incentive.
• The 2024 halving already cut daily new issuance to about 450 BTC.
• Whether fee revenue alone can secure the network is an open research question.

Each halving shifts miner income toward fees and away from the shrinking block reward, and the same 2024 halving that cut daily issuance to about 450 BTC also halved the new-coin portion of that revenue. The fee-only endpoint is the final step of a slope the network has been climbing since 2009 rather than a cliff in 2140.

The shift matters because mining secures the ledger that records the supply in the first place. If fees alone cannot sustain enough mining, the security model that protects every coin would face pressure, which is why the post-issuance economics draw so much research attention. The strength of that security model matters to anyone studying broader cybersecurity threat data, since a well-funded mining network is what keeps the ledger tamper-resistant.

How accurate is the 95% figure for mined bitcoin?

The mined share is precise to the day it is measured. The 95.45% figure comes from dividing the mined supply of about 20,045,225 BTC on June 19, 2026, by the 21,000,000 cap. Blockchain.com on-chain data supplies the mined total, and because the running total is updated with each new block, the percentage creeps upward continuously. Any published share is therefore a snapshot rather than a static fact.

Can the 21 million bitcoin cap ever change?

Changing the cap would require near-universal agreement across the network. The 21,000,000 ceiling is enforced by the reward-halving rules baked into the protocol. In practice, the fixed supply is treated as the core promise of the system, so a change faces both technical and social resistance that makes it highly unlikely.

Conclusion

With about 20,045,225 BTC mined as of June 2026, the network has issued most of its 21,000,000 cap, leaving roughly 954,775 BTC to come. That is 95.45% of all bitcoin that will ever exist. The most useful way to read the supply is as three layers: a fixed ceiling, a mined total that climbs toward it, and a smaller spendable float once likely-lost coins are subtracted. The halving schedule stretches the issuance across more than a century, so the supply story is mostly written even though the final coin is generations away.

For anyone tracking how digital systems handle scarcity, Bitcoin’s fixed cap offers a clean case study, and the same curiosity drives interest in capped or measured systems like web browser usage statistics. The mined total will keep inching upward, but the headline answer to how many bitcoins exist is already set by math rather than markets.
