Splinterlands has an allocation of SPS in the whitepaper dedicated to tournaments roughly worth $35k per month at the current SPS price (after accounting for the 1% per month reduction in inflation). Looking at past tournaments, it seems they gave under $40k over the past 30 days, which makes sense give SPS was a lot higher 30 days ago. Therefore, looking at the tournament payouts it does not seem like market fees subsidize the tournament prizes much, or even at all.
I respect your right to discuss this proposal with the community but I would appreciate you not spreading misinformation.
