Effective Oct 29, 2026: Polymarket Perps lists an Anthropic pre-IPO perp with up to 10x leverage. Affects: Polymarket Perps traders outside the US. Source: api.perpetuals.polymarket.com, verified Nov 3, 2026. Polymarket code dexsheet.
Polymarket Perps, the perpetual futures venue on the international polymarket.com, listed ANT-USD, a pre-IPO perpetual on Anthropic, on 29 October 2026. Polymarket's market data shows the contract going live at 16:34 UTC in a new pre-IPO category, with up to 10x leverage for positions under $500,000, hourly funding and pUSD as collateral.
Anthropic has no listed shares yet, so Polymarket says the contract follows a reference price drawn from the company's private valuation, with funding payments between longs and shorts keeping the perp near that price. Press reports say the reference comes from a Hyperliquid market and that Polymarket plans to convert ANT-USD to a standard perp after an IPO; Polymarket's pre-IPO page does not describe the conversion or what happens if no IPO takes place. The contract gives no ownership of Anthropic shares.
Leverage steps down as positions grow: 10x below $500,000 notional, then 5x, 3x and 2x, and 1x from $5 million. Polymarket's market data lists a reduced fee schedule for this market of 0.02% taker and 0.00625% maker at the base tier, half the standard Perps rates of 0.04% and 0.0125%, with no end date set. On 3 November the contract was quoted near 1,800, with open interest of about 193 contracts.
Trade[XYZ] listed its own Anthropic pre-IPO perp, xyz:ANT, on Hyperliquid on 26 October. That contract references one Anthropic share and traded near $110 on 1 November, so its price is not directly comparable with Polymarket's.
Polymarket Perps does not accept orders from the United States, Canada, Cuba, Iran, North Korea, Syria, Crimea, Donetsk or Luhansk. Polymarket US, the separate CFTC-regulated exchange for US users, does not list this contract.
