Eric Odhiambo's late equaliser ensured that Rangers failed to create their best start to a league season for 112 years with 10 wins out of 10.
Maurice Edu half-volleyed home from 16 yards as the Scottish champions looked like restoring their three-point lead.
A superb Allan McGregor save denied Richie Foran a second-half equaliser.
Ryan Esson denied John Fleck at the other end, but Odhiambo fired in after 81 minutes to preserve Caley Thistle's unbeaten away record since November.
Something had to give at Ibrox, where Rangers were looking for that historic tenth straight win to restore their Scottish Premier League lead over a Celtic side who had earlier defeated St Johnstone 3-0.
Edu broke the deadlock before being taken off injured
Inverness were protecting a record that has now added five games to a run started before their promotion from Division One.
Despite what was at stake in terms of history, Rangers manager Walter Smith rested Steven Naismith and Steven Whittaker ahead of the Champions League trip to Valencia.
Showing five changes, Smith's team was along more familiar lines from the youthful one that beat Motherwell to move into the Co-operative Insurance Cup semi-final in midweek.
But it was an Inverness side showing just one change from their league win over Kilmarnock last weekend, with Kevin McCann replacing Odhiambo, who started the more brightly.
Rangers burst to life after 11 minutes, with the breakthrough coming after Edu had made a mess of his first attempt to control the ball, but it sat up nicely for the midfielder to find the net with his half-volley from 16 yards.
Kenny Miller fired straight at goalkeeper Ryan Esson after a mazy run, while David Weir and Lee McCulloch both headed just wide as Rangers took firm control.
Edu, who had been struggling after a strong Foran challenge, and Weiss were withdrawn at half time, with Naismith and John Fleck, who was making his first appearance of the season following injury, entering the fray.
As Rangers adjusted, Caley Thistle went close to a surprise equaliser.
Referee Ian Brines waved away claims for a penalty after Weir challenged Foran and, seconds later, Nick Ross ought to have done better than volley wide.
Steven Davis sent a drive just wide as Rangers responded, but the Glasgow side had McGregor to thank for staying ahead moments later.
The Scotland goalkeeper somehow managed to scoop Foran's downward header over the crossbar and the forward somehow fired wide after making space for himself from the corner.
It was Esson's turn for heroics seconds later when he turned a Fleck effort out for a corner.
Rangers looked like seeing the match out until Kirk Broadfoot lost possession and Foran rolled the ball into the path of substitute Odhiambo to score.
Jonny Hayes missed a couple of chances for Inverness, while Kyle Lafferty went close at the other end as the game reached a thrilling finale.
It means that Rangers fell short in their aim of winning their opening 10 fixtures - last achieved in 1898/99, when the Ibrox side won all 18 of their league fixtures with William Wilton in charge.
The draw also means that their lead is now only one point from Old Firm rivals Celtic.
