7 percent inflation over a decade is one doubling, so it cuts your 100x return down to 50x. That seems like it might move some needles on valuations.
Meanwhile, the money you invest will also not create quite as much runway for the companies you invest in, so the fraction of successful exits may also decline.
If interest rates appreciate to keep up with inflation, time horizons compress -- future revenue is worth less, and today's revenue is worth more. This drops risk appetite for investors, who move from tech IPO darlings like Rivian to boring stable earners like utilities, so that will also decrease likely valuations your startups get when they IPO, potentially by another order of magnitude, dropping your 50x down to 5x.
