Will Girl with Balloon (by Banksy) sell for £500k or more at Sotheby’s?

Banksy is a pseudonymous England-based street artist, political activist, and film director whose real name and identity remain unconfirmed and the subject of speculation. Sotheby’s nearest biannual Banksy sale is open for bidding from April 20 to 26, 2022. This is a market on the final hammer price for Girl with Balloon – Colour AP (Purple) (Lot 5), to be auctioned at Sotheby’s, where bidding is scheduled to open on April 20 (9:00 AM ET) and close on April 26 (11:05 AM ET), 2022 (https://www.sothebys.com/en/buy/auction/2022/banksy/girl-with-balloon-colour-ap-purple). This market will resolve to “Yes” if the final Hammer Price at auction equals to or exceeds 500,000 GBP, and “No” otherwise. Note: this is a market on the final hammer price at the live auction, which does not include buyer’s premium, fees, or taxes, and is not equivalent to “Lot Sold” price as listed on Sotheby’s website. If, for whatever reason, Sotheby’s does not provide a live broadcast, the recording of the auction, nor the hammer price elsewhere, this market will resolve to the price listed on Sotheby's website. If the auction is cancelled altogether and will not happen by May 3, 11:59:59 PM ET, the market will resolve to "No”.
