The top 11 Bitcoin mining companies by market capitalization have achieved record monthly production levels in October, the highest since the April halving event.

Data from Farside shows that every major publicly listed miner, except Terawulf, posted month-over-month production growth. Collectively, these companies increased production by 13%, bringing total Bitcoin mined in October to 3,630 BTC.

Marathon Digital Holdings (MARA) led the production surge with 717 BTC, while CleanSpark (CLSK) followed with 655 BTC. Riot Platforms (RIOT) also saw notable gains, producing 505 BTC. Terawulf (WULF), however, experienced a slight dip, producing 150 BTC in October, down from 176 BTC in September.

These production milestones were achieved despite rising mining difficulty, which increased twice in October by an average of over 3%, according to Hashrate Index.

This trend has continued into November, with mining difficulty climbing by over 6% so far. The next adjustment, scheduled for November 18, is projected to add more than a 2% increase
