Will Anthropic’s valuation hit … by December 31?

Platform comparison

Market context

The market bets on whether Anthropic’s Nasdaq Private Market (NPM) valuation reaches a specified threshold before 31 December 2026, with current crowd-implied odds at 12% YES. This hinges on secondary-market pricing updates published daily by Nasdaq Private Market, not on headline funding rounds.

Historical precedents show NPM valuations can diverge sharply from primary round figures during late-stage private windows. Anthropic’s Series H-1 round in May 2026 set a formal $965bn post-money valuation, yet NPM data by July 2026 already priced the firm at $1.14tn, an 18% premium [2]. Comparable cases like SpaceX and OpenAI reveal similar gaps: secondary markets often front-run IPO expectations when supply is constrained, as seen when Anthropic’s on-chain pre-IPO value jumped to $1.2tn, overtaking OpenAI for the first time [7][9]. The 12% probability here implies traders doubt a further surge to the listed amount, despite the recent $1.14tn NPM print [1][2].

Key catalysts include the next NPM update cycle, any new Series H-2 or bridge financing announcements, and shifts in Claude adoption metrics that could fuel secondary demand. A recent surge in valuation from $650bn in early May to $992bn by late May underscores how quickly sentiment can move [6]. Traders should monitor Forge Global and Caplight data, where valuations have already crossed $1tn, and watch for any regulatory or IPO-timing signals that could alter liquidity dynamics [8][9]. The divergence between prediction-market odds (12%) and crypto-native markets (99% for $1tn, 95% for $1.1tn) highlights a stark split in consensus [4].
