Anthropic IPO Bet: Fast Growth Has to Outrun Nearly $900 Billion in Spending

Anthropic has reached adjusted operating profit just ahead of its expected public listing, but the real question for buyers is whether growth can keep pace with what the company has promised to spend.

Anthropic Profit: Adjusted vs GAAP Results

Per the prospectus, adjusted operating income turned positive in the second quarter of 2026 and stayed positive in the third, totaling $4.08 billion for nine months. That figure leaves out stock based pay, noncash charitable gifts and payments from a copyright class action settlement. Under GAAP, the operating loss was $1.26 billion. Net loss topped $104 billion against $5.6 billion of adjusted net income, largely because of a $94 billion noncash charge tied to securities issued to partners such as Google and Amazon.

What Investors Are Betting On

Anthropic’s roadshow projects compute costs settling at 45% to 50% of revenue and a long term adjusted margin near 35%. Revenue rose 1,206% year over year in the first nine months, and analysts says it must keep climbing toward hundreds of billions annually for the math to work.
