MARA Holdings (MARA) is drawing attention after reporting second quarter 2026 earnings that showed lower sales and a swing to a large net loss, alongside an expansion focused on AI and digital infrastructure.

MARA Holdings shares have been weak in the short term, with the 7 day share price return down 18.64% and the 30 day share price return down 24.13%, while the 1 year total shareholder return is down 38.95%. This suggests momentum has been fading even as the company reports large losses, reshapes its board and pursues new AI and power infrastructure projects.

After such a sharp share price fall alongside heavy losses and an AI focused build out, MARA Holdings now pits fear of catching a falling knife against the risk of missing a reset. So how does the current valuation stack up?

Most Popular Narrative: 47.3% Undervalued

The most followed narrative currently points to a fair value for MARA Holdings of $18.13, which is well above the last close of $9.56. That gap is based on a detailed view of how its energy and compute assets could be used over time.

MARA's strategic expansion into AI infrastructure and partnerships with leading AI and grid management companies positions the firm to benefit from the accelerating adoption of artificial intelligence and the growing demand for high-performance, energy-efficient compute, which is likely to unlock new, recurring revenue streams outside traditional bitcoin mining.

Want to see how that AI and power build out turns into a valuation story for MARA Holdings? The core of this narrative is a long runway for high margin compute revenue layered onto an already large energy footprint, supported by a detailed set of assumptions on future profitability and share count that sit behind the $18.13 fair value.

Result: Fair Value of $18.13 (UNDERVALUED)

However, the MARA Holdings story still carries clear risks, including heavy reliance on bitcoin mining economics and large capital needs for new power and compute projects.

Another View: MARA Holdings Through A Price To Sales Lens

The fair value narrative for MARA Holdings sits at $18.13, yet its current P/S ratio of 4.6x tells a different story. That is higher than both the US Software industry at 3.8x and the fair ratio estimate of 1.6x, which points to meaningful valuation risk if sentiment cools.

For investors weighing this against the earlier fair value argument, the question is whether MARA Holdings can grow into that richer P/S profile or whether the market could drift closer to the lower fair ratio instead.
