The claim "largest single commercial launch deal" is somehow a bit marketing. A launch deal often includes multiple launches of satellite for a multiple years contract. Looking at Arianespace yearly turnover (more than 1000 MEUR in 2009) or ILS, the deal is high but still inline with existing launch deal. Arianespace made 6 launches in 2009 including ESA/research satellite... for a turnover of 1 Billion EUR. We could assume the price of a launch is around 100-200 MEUR... The SpaceX launch will include multiple satellite in one launch. So we are still at a comparable cost for the launch (especially knowing the insurance cost too...).
