Looking at Marqeta and Block's sales multiple, there's a 33% dispersion that will likely narrow if the current momentum trend continues. MQ is valued higher than Block on sales multiple, while it's expected to experience growth contraction due to 2 contract renewals that will occur in Q3 of 2026. On the other hand, Block is witnessing gross margin improvements and higher growth expectations. This dynamic presents an interesting pair trade, but a risk could be an acquisition offer for MQ.
