Bitcoin Hashrate Slumps 17% as Miners Pivot to $26.6B AI Deals

Woofun AI reports that a strategic retreat in Bitcoin network security has emerged, driven by miners reallocating capital toward high-margin AI infrastructure deals involving Hut 8, Core Scientific, TeraWulf, and IREN.

The network's computational power has receded from its zenith, with CryptoQuant data indicating a 17% decline from peak levels. Recent estimates place the hashrate between 850 and 920 exahashes per second as of August 13, 2026. This contraction follows a drop in mining difficulty in early August, signaling that capacity has temporarily exited the network. Compounding the pressure, publicly traded miners sold more than 32,000 BTC during the first quarter, exceeding their combined sales throughout 2025.

Structurally, Bitcoin's protocol automatically adjusts mining difficulty, allowing efficient operators to survive while weaker players reduce output. Post-halving economics have forced a rigorous focus on electricity costs, hardware efficiency, and liquidity. Consequently, publicly traded miners have accelerated Bitcoin sales and slowed expansion plans to preserve capital. This operational tightening reflects a broader industry response to squeezed margins and the need for immediate cash flow.

Woofun AI data shows that the pivot to AI and HPC is the primary growth engine, with Hut 8 announcing a second 15-year, 352 MW lease at Beacon Point in July. This deal increased its contracted AI capacity to 949 MW, pushing aggregate base-term contract values to $26.6 billion. CoinShares estimates that listed miners could generate 70% of revenue from AI and HPC by the end of 2026, up from 30%. Across the public mining sector, more than $70 billion in cumulative AI and HPC contracts have been announced, highlighting the scale of this new revenue stream.

This transition offers crypto investors a new framework for evaluating mining companies. Instead of relying exclusively on Bitcoin production, firms can allocate selected sites to AI compute while retaining the option to redirect capacity toward Bitcoin when mining economics become more attractive. This flexibility marks a fundamental shift in asset allocation for the sector.
