Not possible (unless you're talking double gzip). gzip's max compression ratio is 1032:1[1]. So 100kB can expand to at most ~103MB with single gzip.
Brotli allows much larger compression. Here's[2] a brotli bomb I created that's 81MB compressed and 100TB uncompressed. That's a 1.2M:1 compression ratio.
