Extended FDV above … one day after launch?

Platform comparison

Market context

Extended, a blockchain application focused on conditional order execution and portfolio automation, is preparing a token launch with a publicly tradable supply. The market resolves based on whether the fully diluted valuation—calculated by multiplying total token supply by the price observed on the most liquid exchange 24 hours after public trading begins—exceeds a specified threshold. For traders building automated monitoring systems, the key technical requirement is that the token must be actively transferable and listed on a major exchange; resolution hinges on a single price snapshot at 4:00 PM ET on the day following launch, making real-time data feeds and exchange API integrations essential for position management.

Historical token launches from infrastructure-focused projects reveal substantial variance in day-one FDV outcomes. Uniswap's 2020 launch saw a $1.3bn FDV within hours before stabilising lower; Arbitrum's 2023 launch peaked at $2.6bn on day one before retracing. Projects with established user bases and clear utility tend to command higher initial valuations, whilst those dependent on speculative positioning often see sharp volatility. The 14% implied probability suggests the market is pricing in a relatively conservative launch scenario, consistent with modest initial liquidity or cautious market reception for a new automation-focused protocol.

Traders should monitor Extended's official communications for exact launch timing, initial token allocation details, and exchange listings. The settlement window closing on 1 January 2027 provides substantial runway, but early momentum typically determines day-one FDV. Watch for announcements regarding airdrop mechanics, lockup schedules, and institutional participation, as these directly influence opening-day trading volume and price discovery. Integration readiness with major DEXs and CEXs will be critical for establishing the "most liquid price source" used for resolution.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
