To wit, for all of the disorientation caused by a $450m auction price, the art market is not most active and competitive at the very top. The day sales in Contemporary art were a hotbed of competitive activity and a major increase in sales volume. The rise of highly managed sales back-stopped by third-party guarantees has meant that a significant portion of the top of the art market is non-competitive. Contrast this with the day sales which achieved a sell-through rate of 88%, just three percentage points below the Evening sales, without the financial supports of third-party guarantees or irrevocable bids. Nearly 30% of the value in the Contemporary evening sales were sold at the low estimate or below. Almost 83% of the value was sold at or below the high estimate.
