    How is bitcoin's price determined? Supply, demand and halvings

    No central bank or company sets bitcoin's price. It is set by supply and demand across many trading platforms.[1] Supply grows on a fixed schedule that halves about every four years.[2] Demand shifts with ETF flows, leverage and interest rates, so the price is volatile: bitcoin fell about 50% from its October 2025 record by February 2026.[3][4][5]

    Editor reviewedStrict sourcingUpdated CryptoMarkets and trading

    This is the starting point for our crypto markets course. It explains why bitcoin’s price moves, with dated examples from 2025 and 2026, starting from the basic fact that its value comes from supply and demand.[1] It is not financial advice, and the prices quoted are historical, not live.

    Supply and demand, with no price-setter

    Bitcoin has no company or central bank behind it that sets a price. The price is whatever buyers and sellers agree on, on trading platforms and in private trades.[1] Because it trades on many platforms around the clock, any “bitcoin price” is a snapshot. On October 9, 2026, Fortune quoted $82,413.19 at 6:45 a.m. ET.[6] A week earlier, The Block quoted about $86,626.[7]

    Funds that hold bitcoin value it with composite reference rates. These are built to resist manipulation and give a real-time, volume-weighted fair value.[8] One such index applies its algorithm to per-second prices from its constituent platforms over 24 hours and gives more weight to more liquid venues.[9]

    The supply side: a fixed schedule

    New bitcoin is created as a reward for miners, who add a block of transactions about every 10 minutes. The reward is currently 3.125 bitcoin per block.[10] Every 210,000 blocks, roughly every four years, the reward halves.[2] The total can never exceed 21 million coins. About 20.0 million existed at the end of 2025.[11]

    The fourth halving, on April 19, 2024, cut the subsidy from 6.25 to 3.125 BTC. The next is expected in mid-2028.[12][2] After the 2012, 2016 and 2020 halvings, prices rose to cycle highs of roughly 93x, 30x and 8x their halving-day levels. The rallies shrank each time.[13] Goldman Sachs cautioned in 2024 against extrapolating those cycles, because each came in different macro conditions.[14] After the October 2025 crash, some traders said the four-year pattern “has changed.”[15]

    The demand side: flows, leverage and rates

    Spot bitcoin ETFs let people buy exposure through a brokerage account. Their weekly flows can be large: about $2.4 billion went in during the week ending September 25, 2026.[3] Many traders also use borrowed money, through products such as perpetual futures.[16] When prices fall fast, exchanges force-close those bets, which pushes prices down further. On October 10, 2025, about $19 billion of such positions were wiped out as bitcoin fell from about $122,000 to $105,000.[4]

    A year after the October 2025 crash, perpetual futures remain a major part of crypto trading, and round-the-clock trading with heavy leverage made crypto the hardest-hit market in that selloff.[16] Liquidation cascades also run upward. In August 2026, a short squeeze closed nearly $3 billion of mostly bearish positions in a day.[17] Interest rates may also matter. Stifel argued in early 2026 that “hawkish” Fed cuts weighed on bitcoin. Binance Research found its correlation with US real yields at -0.31 in August 2026.[18] The Fed raised rates on September 16, 2026, but bitcoin was higher two weeks later.[19][20][7]

    Why it is so volatile

    Bitcoin’s price swings are large. It fell from about $126,000 in October 2025 to below $64,000 on February 5, 2026.[21][5] Single-day moves of more than 10% still happen.[22]

    CoinDesk measured bitcoin’s annualized volatility at about 46% in 2026, against 84% in 2018. It still counted 10 “three-sigma” days in 2026, more than in all of 2018.[22] Since 2024, bitcoin’s volatility of roughly 47% has matched Nvidia’s. Bitcoin logged 26 three-sigma days in that time, against Nvidia’s eight.[23]

    Questions readers ask

    Who sets the price of bitcoin?

    Nobody sets it. Bitcoin's value comes from supply and demand on digital asset trading platforms and in private trades.[1]

    Why is the bitcoin price different on different websites?

    Bitcoin trades on many platforms around the clock, and each quote is taken at a different moment. Funds use reference indexes that weight prices from several platforms over 24 hours.[9][8]

    Does the halving make the price go up?

    Past halvings in 2012, 2016 and 2020 were each followed by a new price high. Goldman Sachs cautioned against extrapolating those cycles, and the halving itself does not mechanically move the price.[13][14]

    How volatile is bitcoin?

    CoinDesk put bitcoin's annualized volatility at about 46% in 2026, down from 84% in 2018. It still counted 10 days with moves of at least three standard deviations in 2026, more than in all of 2018.[22]

    Fortune quoted $82,413.19 at 6:45 a.m. ET on October 9, 2026. Prices change continuously; check a live source for the current price.[6]
