Your market share estimates for the Google and TradeDesk DSPs are very close to an estimate published by the Wall Street Journal on 3/4/21 (in an article titled "Google Crushed Many Digital Ad Rivals. But a Challenger Is Rising."). You estimated 42% and 8% respectively, and they estimated 40% and 8%. So this helps to support that your estimates are in the right ballpark.
