Thiel's Palantir holdings have increased in value by about $3 billion since the earnings report and $2 billion since the election.
In September, S&P Global announced Palantir would join the S&P 500 stock index.
Analysts at Argus Research say the rally has pushed the stock too high given the current financials and growth projections. The analysts still have a long-term buy rating on the stock and said in a report last week that the company had a "stellar" quarter, but they downgraded their 12-month recommendation to a hold.
