I have looked at the top SPS holders from the API richlist that Splinterlands provides, compared it against HIVE holders and out of the top 200 total SPS holders there is around 50 accounts that holds more than 10k total HIVE.

The top richlist of 200 starts somewhere at 500k SPS, so the data is cut out, if I manage to provide a longer list of SPS holders that will go down to 200k SPS I will update you.

Here is a screenshot for the top holders:
