Will Anthropic’s valuation hit … by December 31?

Platform comparison

Market context

Anthropic’s private market valuation has already crossed $1.14 trillion as of July 2026, according to Nasdaq Private Market’s latest NPM Price, placing the $12% YES probability on Polymarket for a higher December 2026 target in sharp contrast to its current reality[2]. This market prices the chance that NPM will report a valuation at or above the listed amount before year-end, with settlement tied to USDC on Polygon and resolved via conditional tokens once the NPM data window closes[3].

Historically, Anthropic’s valuation has surged from $350 billion in early 2025 to $965 billion by May 2026, then jumped another 18% to $1.14 trillion in just weeks, outpacing OpenAI and becoming the world’s most valuable AI firm[6][8]. Comparable pre-IPO trajectories in tech show that once a company breaches the trillion-dollar mark, further 20–30% gains within six months are common if funding momentum persists, as seen in Anthropic’s own 20% climb over seven days to $1.2 trillion implied value[9].

Traders should monitor upcoming funding announcements, particularly the $65 billion round closed in May 2026, and any follow-on term sheets expected in Q3 2026, as these directly influence NPM updates[8]. The next NPM Price refresh occurs daily at 1:00 PM ET, and any new strategic investment from Microsoft, Nvidia, or Amazon—already committed up to $15 billion in late 2025—could push valuation past $1.5 trillion, a level currently priced at 78% by Polymarket[3][6].
