Bitcoin Hashrate Drops in Q1 2026 as Miners Eye AI

Bitcoin Hashrate Posts First Q1 Decline in Six Years

Bitcoin's network hashrate has experienced a notable downturn in the first quarter of 2026, dropping approximately 4% year-to-date and slipping below 1 zettahash per second (ZH/s) for periods. 63 64 This marks the first such quarterly decline since 2020, reversing five years of double-digit growth. 48 Current levels hover around 943 EH/s to a recent recovery at 1.02 ZH/s, influenced by post-halving economics, BTC prices near $66,800, and escalating energy costs from geopolitical tensions like the Iran conflict pushing oil above $119 per barrel. 12

The shift underscores Bitcoin's adaptive difficulty mechanism at work, designed to maintain ~10-minute block times despite external shocks. Weak operators are powering down inefficient ASICs, allowing resilient miners with low-cost power to consolidate. 53

Sharp Difficulty Adjustments Signal Network Recalibration

On March 21, 2026, Bitcoin's mining difficulty plunged 7.76% to 133.79 trillion, the second-largest drop of the year after a -11.16% adjustment in February—the biggest since the 2021 China ban. 39 40 Hashrate had retreated ~20% in under a month prior, prompting this recalibration at block 941,472. 44

The next adjustment, due April 3, anticipates a +6.4% rise, potentially pressuring margins further as hashrate stabilizes. 15 CoinWarz charts show difficulty ~9.8% below late-2025 peaks, flushing marginal players. 43

Key Stats:

Q1 2026 Hashrate: ~943-1,020 EH/s (down from 1.2 ZH/s peaks).

Difficulty: 133.79T (post-March drop).

Hashprice: ~$31.60/PH/s/day, down to $28 in Feb.

Miner Operations Face Squeezed Margins

CoinShares' Q1 2026 report reveals 15-20% of miners operating at losses, with production costs ~$82,600 per BTC against spot ~$68,000—equating to ~$14,000-$19,000 shortfalls per coin mined. 13 15 Rising oil impacts 8-10% of global hashrate tied to sensitive energy markets. 12

Public miners like Bitfarms, Riot, and Hut 8 exemplify the strain, redirecting infrastructure. 17 Accumulation addresses absorbed 67K BTC as miner selling eased, signaling HODLer confidence. 57

Accelerating Pivot to AI and HPC

Miners are repurposing sites for AI compute, where margins triple BTC mining's. Public firms could derive 70% revenue from AI by year-end, up from 30%. 31 IREN initiated in 2025; others follow amid hashprice collapse. 32

This exodus—especially from North America—could stall hashrate growth, but boosts energy efficiency via waste heat reuse. 0 US holds 37.5% global hashrate (~400 EH/s) in Q1. 55

Mining Pool Concentration Raises Flags

A rare 2-block reorg at height 941,881 highlighted centralization: Foundry's chain overrode AntPool and ViaBTC post-difficulty drop. 22 Foundry also launches Zcash pool, betting on privacy coins. 21

Pool stats show distribution shifting; 4+ consecutive blocks by one pool risks history rewrites. 11 Braiins, Binance pools active amid debates.

US Policy Push for Domestic Mining

Senators Cassidy and Lummis introduced the 'Mined in America Act,' offering certifications, tax incentives, and bans on adversarial hardware (China/Russia). Ties to Trump's Bitcoin reserve, integrating mining into energy programs. 1
