To this end, the study employs the multiscale quantile\u2010on\u2010quantile correlation (MSQQC) and multiscale quantile\u2010on\u2010quantile partial correlation (MSQQPC) approaches, using daily data covering 02\/01\/2019\u201316\/06\/2025. The results indicate that BTC\u2013AI comovement is strongly state\u2010 and frequency\u2010dependent rather than stable across the joint distribution or across horizons. In the high\u2010frequency band, dependence is weak and only intermittently significant, with localised negative regions around BTC\u2009\u2248\u20090.20 with AI\u2009\u2248\u20090.30\u20130.50 and BTC\u2009\u2248\u20090.30 with AI\u2009\u2248\u20090.70. In the mid\u2010frequency band, significance concentrates in the tails, showing negative dependence under downside stress conditions such as BTC\u2009\u2248\u20090.10\u20130.30 with AI\u2009\u2248\u20090.10, alongside sign changes when BTC is in upper\u2010tail states. In the low\u2010frequency band, dependence becomes broadly positive and significant across most quantile combinations, with limited decoupling when AI is highly elevated (\u2248\u20090.80\u20130.90) and BTC is also in upper quantiles (\u2248\u20090.70\u20130.90). Importantly, conditioning on VIX and VVIX does not materially alter these patterns, suggesting that sentiment influences segments of short\u2010run dependence but does not overturn the longer\u2010run BTC\u2013AI linkage. The study derives policy recommendations from these findings.<\/jats:p>","DOI":"10.1155\/jama\/7926803","type":"journal-article","created":{"date-parts":[[2026,3,23]],"date-time":"2026-03-23T09:04:02Z","timestamp":1774256642000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Bitcoin Comovement With AI Equities Beyond Equity Risk Sentiment: Evidence From Multiscale Quantile\u2010on\u2010Quantile Partial Correlation"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0094-1778","authenticated-orcid":false,"given":"Tomiwa Sunday","family":"Adebayo","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5733-5045","authenticated-orcid":false,"given":"Dervis","family":"Kirikkaleli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,3,23]]},"reference":[{"key":"e_1_2_13_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.frl.2019.04.019"},{"key":"e_1_2_13_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.frl.2016.09.025"},{"key":"e_1_2_13_3_2","unstructured":"BIS BIS Quarterly Review December 2024 2024 https:\/\/www.bis.org\/publ\/qtrpdf\/r_qt2412.htm."},{"key":"e_1_2_13_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.physa.2024.129589"},{"key":"e_1_2_13_5_2","doi-asserted-by":"publisher","DOI":"10.3905\/jpm.2000.319728"},{"key":"e_1_2_13_6_2","doi-asserted-by":"publisher","DOI":"10.1017\/S0022109018001436"},{"key":"e_1_2_13_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.qref.2025.102006"},{"key":"e_1_2_13_8_2","article-title":"Institutional Investments in Crypto Exchange-Traded Funds on the Rise (Eco Notepad) [Working paper]","author":"Benahmed R.","year":"2025","journal-title":"Banque de France"},{"key":"e_1_2_13_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.najef.2019.03.019"},{"key":"e_1_2_13_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.frl.2019.101399"},{"key":"e_1_2_13_11_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10614-022-10318-7"},{"key":"e_1_2_13_12_2","doi-asserted-by":"publisher","DOI":"10.22201\/fca.24488410e.2023.3396"},{"key":"e_1_2_13_13_2","doi-asserted-by":"publisher","DOI":"10.3390\/e25020377"},{"key":"e_1_2_13_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclepro.2022.131089"},{"key":"e_1_2_13_15_2","doi-asserted-by":"publisher","DOI":"10.32479\/ijeep.14996"},{"key":"e_1_2_13_16_2","doi-asserted-by":"publisher","DOI":"10.3390\/jrfm16090412"},{"key":"e_1_2_13_17_2","doi-asserted-by":"publisher","DOI":"10.48550\/arXiv.2501.09911"},{"key":"e_1_2_13_18_2","volume-title":"Tail Connectedness Between Robotics and AI ETFs and Traditional Us Assets Under Different Market Conditions: A Quantile Var Approach","author":"Belhouichet F.","year":"2025"},{"key":"e_1_2_13_19_2","doi-asserted-by":"publisher","DOI":"10.1080\/00036846.2023.2167921"},{"key":"e_1_2_13_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.iref.2025.104775"},{"key":"e_1_2_13_21_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.intfin.2023.101929"},{"key":"e_1_2_13_22_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10614-025-11142-5"},{"key":"e_1_2_13_23_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jimonfin.2024.103235"},{"key":"e_1_2_13_24_2","doi-asserted-by":"crossref","unstructured":"TorresM.
