NextBigFuture reports SpaceX Q4 2026 capex expected to show cash-flow breakeven; Google's $920M/month workspace lease hits full rate.

SpaceX's fourth quarter of 2026 could demonstrate cashflow positive performance for its AI infrastructure business, with full details expected during the company's November 2026 earnings call. The catalyst: Google's $920 million monthly lease reaches full rate on October 1, while Anthropic and Reflection AI are already paying at committed levels. For the first time, three signed compute contracts will operate at full capacity within the same quarter, leveraging infrastructure whose capital expenditure was completed in 2025 and early 2026.

The AI segment, which posted a $2.47 billion loss on $818 million in revenue during Q1 2026, is expected to swing to operating profitability roughly two quarters later without requiring additional deals. However, opportunities exist for agreements comparable in scale to Google and Anthropic.

The traditional narrative has framed SpaceX's AI business as a construction story: build gigawatt-scale capacity, secure tenants, or monetize Grok's frontier capabilities while growing into capital investments. Epoch AI's tracking data suggests a different picture. Substantial capacity already stands operational, with more being added, and roughly half of it is leased. A key lever exists in allocation decisions between training Grok internally and selling Grok services to external customers.

According to Epoch AI's analysis, Colossus 2 reached 440,000 installed chips by July 1, 2026—110,000 B200s and 330,000 B300s, equivalent to approximately 1.112 million H100-equivalent units. These chips draw 946 megawatts of IT power and represent an estimated $35.8 billion capital investment. Of the 440,000 installed chips, approximately 223,000 operate under lease: 110,000 for Google, 95,000 for Anthropic, and 18,000 for Reflection AI.

This leaves 217,000 installed, powered, and operational chips generating no external revenue. These chips are not idle—they train Grok and Cursor—but at Google's marginal rate of approximately $8,400 per chip per month, SpaceX's internal allocation of this capacity represents roughly $22 billion annually in foregone revenue.
